Description

Mechanical Control Fluid Injection System {AUTOMATIC FLUID SPRAY SYSTEM OF MACHANICL CONTROL TYPE}

The present invention relates to a non-electric fluid automatic injection system for automatically controlling the injection of the fluid, and to a mechanically controlled fluid automatic injection system that operates mechanically by the heat energy transferred from the outside.

In general, buildings are heated by roofs and exterior walls where the most solar radiation is emitted. In these buildings, the roof, which rarely casts shadows, is heated for the longest by sunlight. Therefore, the roof is the most important factor in determining the temperature of the building.

However, these roofs act as a factor in excessively raising the temperature of the building in summer. In particular, in the case of factories, there is a problem that the air conditioner must be operated excessively in midsummer as the temperature of the building rises. Therefore, in the case of factories, excessive electricity is generated in summer.

Recently, a system for automatically injecting a fluid such as cooling water (for example, tap water or groundwater) has been developed and used. Such automatic fluid injection systems are mainly used for machining devices and lawns. In addition, the fluid automatic injection system is installed on the roof of the building as described above is also used as a device for cooling the roof (hereinafter referred to as 'roof cooling system'). In other words, the fluid automatic injection system is used as a roof cooling system.

As shown in FIG. 1, a roof cooling system using a general fluid automatic injection system is provided with a cooling water pumped from a pump P to a roof through a nozzle N of a branch pipe S branched from a pump pipe PA. Sprayed. At this time, the branch pipe (S) is injected and opened by the solenoid valve (SV) operated by the controller (CT) to spray the coolant to the roof.

Here, the controller CT operates the solenoid valve SV according to the temperature sensed by the thermal sensor HS. That is, the controller CT operates the solenoid valve SV when the temperature detected by the thermal sensor HS is high, and stops the operation of the solenoid valve SV when the temperature is high.

As described above, the thermal sensor HS is installed between the nozzles N to apply a high temperature signal to the controller CT by heat of a roof heated by sunlight. The thermal sensor HS applies a low temperature signal to the controller CT while being cooled by the coolant sprayed from the nozzles N. The thermal sensor HS is between three nozzles N in a substantially triangular shape, as shown, so as to be cooled by the coolant sprayed from at least one nozzle N among the plurality of nozzles N. Is installed on.

However, such a general roof cooling system, that is, a general fluid automatic injection system is a branch pipe (S) connected to the pumping pipe (Pa), and a wire pipe (WP) with a power line for supplying power to the solenoid valve (SV) In addition, since both the temperature sensor (HS) and the connection line pipe (CP) with built-in connection lines connected to the temperature sensor (HS) and the controller (CT) must be provided, the manufacturing cost and installation time (construction period) are extremely excessive. There is a problem.

In addition, when the power line of the solenoid valve (SV) and the connection line of the temperature sensor (HS) is disconnected, there is a problem that the operation is impossible.

In addition, when the coolant of the nozzle N is not injected to the temperature sensor HS due to external factors such as wind, the controller CT determines that the roof is continuously in a high temperature state and continues to operate in the coolant spray mode. There is also.

Hereinafter, with reference to the accompanying drawings, the machine controlled fluid automatic injection system according to the present invention will be described as follows. The attached FIG. 2 schematically shows the configuration of the machine controlled fluid automatic injection system according to an embodiment of the present invention. 3 is a longitudinal sectional view showing an enlarged view of the valve device shown in FIG. 2, and FIG. 4 is a longitudinal sectional view showing an operating state of the valve device shown in FIG.

2, the mechanically controlled fluid injection system according to an embodiment of the present invention includes a pump 110 having a pumping pipe 112 as shown; A branch pipe 120 having a nozzle 122; It includes; valve device (VA) having an intermittent valve 130 and the heat-sensitive valve 140. This mechanically controlled fluid injection system can be installed and used on the roof of a building as shown. Therefore, in the following description, the above-described mechanically controlled fluid automatic injection system will be described as an example applied to the roof of a building. In addition, the fluid to be described describes cooling water such as tap water or ground water as an example.

In the mechanically controlled fluid injection system, the coolant pumped from the pump 110 is branched to the branch pipe 120 through the pump pipe 112 and sprayed to the roof through the nozzle 122. At this time, the branch pipe 120 is opened and closed by the valve device (VA). That is, the branch pipe 120 injects the coolant when the valve device VA is opened and stops the injection of the coolant when the valve device VA is closed.

Here, the valve device (VA) described above intercepts the cooling water flowing through the branch pipe (120), if necessary, as the intermittent valve 130 opens and closes the branch pipe (120) by the heat-sensitive valve (140). At this time, the heat-sensitive valve 140 is automatically operated by the heat of the roof to control the operation of the intermittent valve 130. That is, the thermosensitive valve 140 is an element that controls the operation of the intermittent valve 130.

On the other hand, the intermittent valve 130 may be provided with the same valve seat VS having a bypass passage (BP) to be described later. The valve seat VS which has such a bypass flow path BP is mentioned later.

Accordingly, the mechanically controlled fluid injection system according to the embodiment of the present invention can maintain the roof at a constant temperature (set temperature) at all times.

Referring to Figure 3, the above-described intermittent valve 130 and the heat-sensitive valve 140 is integrally coupled to constitute a valve device (VA). At this time, the intermittent valve 130 is integrally connected to the branch pipe 120 as shown, and constitutes a part of the branch pipe 120 substantially. Here, the configuration of the intermittent valve 130 and the heat-sensitive valve 140 as described above in more detail as follows.

The intermittent valve 130 is installed in the branch pipe 120 is formed in the form of a pipe as shown. The intermittent valve 130 may flow through the cooling water of the branch pipe 120 as the connection pipe 132 to be described later is formed like a pipe. Such an intermittent valve 130 opens and closes the branch pipe 120 by the water pressure of the cooling water supplied from the branch pipe 120 as described below. Therefore, the intermittent valve 130 interrupts the cooling water of the branch pipe 120.

Here, the above-described intermittent valve 130, for example, as shown in the connecting pipe 132; Diaphragm 134; A press body 136; Case 138; can be configured to include.

As shown in the connection pipe 132 is connected to the branch pipe 120 receives the cooling water from the branch pipe (120). As shown in the connecting pipe 132, a blocking wall 132a for blocking the flow of cooling water is formed perpendicular to the inner circumferential surface. In addition, the connecting pipe 132 has a bypass hole 132b through which cooling water bypasses at an end portion of the blocking wall 132a that is blocked by the diaphragm 134 described later.

The diaphragm 134 shields the bypass hole 132b as described above. The diaphragm 134 has a communication hole 134a through which coolant is communicated as shown. As described later, the diaphragm 134 opens and closes the bypass hole 132b while being lifted by the hydraulic pressure of the coolant filled in the communication hole 134a and filled in the chamber 138a of the case 138 which will be described later. That is, the diaphragm 134 opens and closes the bypass hole 132b by the hydraulic pressure of the cooling water.

The pressing body 136 elastically pressurizes the diaphragm 134 to suppress the lifting of the diaphragm 134. The pressurizing body 136 may include, for example, a coil spring 136a disposed on the diaphragm 134 as shown; And a support plate 136b fixed to the diaphragm 134 to support an end portion of the coil spring 136a. That is, the pressing body 136 may include a coil spring 136a and a support plate 136b. Here, the support plate 136b not only firmly supports the end of the coil spring 136a but also prevents the diaphragm 134 from directly contacting the diaphragm 134 so that the diaphragm 134 is damaged by the coil spring 136a. prevent.

The case 138 has a chamber 138a in which the pressurizer 136 is embedded and at the same time the cooling water is filled as shown. As illustrated, the case 138 may be integrally provided with a valve seat VS having a bypass flow path BP communicating with the chamber 138a. Of course, the valve seat VS having the bypass flow path BP may be configured to be separate from the case 138, as illustrated. The case 138 as described above protects the diaphragm 134 while shielding the bypass hole 132b.

On the other hand, the thermosensitive valve 140 opens and closes the valve seat VS as described above while operating by external heat. The thermosensitive valve 140 opens and closes the valve seat VS to adjust the water pressure of the coolant flowing through the intermittent valve 130. Therefore, the thermosensitive valve 140 controls the operation of the control valve 130 through the water pressure of the cooling water.

That is, the case 10 may be divided into a plurality of configurations. However, the case 10 may be configured as a single cylindrical tube according to the characteristics of the parts to be embedded.

The case 10 has a case through hole 10a through which one end thereof is opened and one end of the driving member 20 penetrates as shown in the enlarged view “A”. That is, the case 10 is not integrally coupled with the driving member 20.

The driving member 20 provides a driving force by using heat energy transferred from the outside. That is, the driving member 20 generates a driving force in accordance with the temperature of the roof. Such drive member 20 includes, for example, a housing 22 connected to a rod R as shown; It may be configured to include; an expansion material for compressing the rod (R) while expanding and contracting by the heat transferred to the outside is embedded in the housing (22). That is, the driving member 20 may include a housing 22 and an expansion material.

Here, the above-mentioned expandable material may be composed of, for example, a wax 24 which is expanded while being phase-converted from a solid phase to a liquid phase in accordance with the temperature of heat that is embedded in the housing 22 and transferred from the outside. This wax 24 is expanded at a temperature of about 30 ℃ to 95 ℃ when the heat-sensitive valve 140 according to an embodiment of the present invention is applied to the roof cooling system, the building can be heated to a high temperature by radiant heat It is preferable to select and configure among the waxes which have a characteristic.

As shown, the driving member 20 shields between the wax 24 and the rod R, which are expanded materials, inside the housing 22, and expands and deforms due to the elastic force of the wax 24. Diaphragm 26 for pressing the; The diaphragm 26 and the rod (R) is filled between the pressurized oil 28 to press the rod (R) while being compressed by the pressing force of the diaphragm (26); may be configured to further include. At this time, the diaphragm 26 serves to separate the wax 24 and the pressurized oil 28 and transmits the expansion force of the wax 24 to the pressurized oil 28. Here, the reason why the pressure oil 28 is further included as described above is that since the oil has better fluidity than the wax 24, the expansion force of the wax 24 can be transmitted to the rod R more quickly. to be.

The drive member 20 is inserted into the case through hole 10a as shown in the enlarged view “A” so that the housing 22 is spaced apart from the case 10 by a gap. Therefore, the driving member 20 can be moved in the state inserted into the case through-hole (10a) if necessary.

The rod R is embedded in the case 10 as shown. This rod R is embedded in the case 10 in a state of being fitted into a cylinder 42 to be described later. The rod R is pressed by the driving force of the driving member 20. That is, the rod R is pressurized by the expansion force of the wax 24.

The movement preventing member 30 prevents the rod R from being moved while being pressed by the driving member 20. That is, the rod R may not move due to the movement preventing member 30 even when the rod R is pressed by the driving member 20.

That is, the support protrusion 32 is installed at the end of the rod (R) is seated on the step (14a) of the case (10).

And, the contact preventing means is, for example, as shown in the enlarged view "b" accommodating groove 34 that can accommodate the support protrusion 32 in a portion of the switch 50 corresponding to the support protrusion 32 in the form of a rod. It is preferable that the switch 50 is formed to be cut along the moving path of the switch 50 so that the switch 50 moves in a state in which the support protrusion 32 is accommodated in the receiving groove 34. At this time, the receiving groove 34 is preferably formed in the shielding sleeve 52 of the switch 50 to be described later, as shown enlarged.

The valve cooling member 150 includes, for example, a bypass tube 152 for bypassing the cooling water supplied from the branch pipe 120 to the thermosensitive valve 140; And a nozzle 154 for spraying coolant from the end of the bypass tube 152 to the thermosensitive valve 140. Of course, the bypass tube 152 is connected to the connecting pipe 132 of the intermittent valve 130 as shown, and receives the cooling water flowing through the branch pipe 120 through the connecting pipe 132, Cooling water is injected into the housing 22 as the end to which the nozzle 154 is coupled is adjacent to the housing 22 of the driving member 20.

Such a valve cooling member 150 needs to further include a bypass tube 152, as shown in the figure, a distance maintaining hole for maintaining a set distance with the thermosensitive valve 140. This distance holding element is an element that keeps the end of the bypass tube 152 provided with the nozzle 154 at a distance (set distance) that is always adjacent to the housing 22 of the driving member 20.

For example, as shown in FIG. 1, a distance spring is wound on one end of the bypass tube 152 to which the nozzle 154 is fastened, and a winding spring 156 wound on the other side to the thermosensitive valve 140. Can be configured. Such a winding spring 156 is secured to one side, so that one side is wound several times on one end of the bypass tube 152, as shown in the other side, the driving member 20 as shown in the enlarged view "D" ) Is wound around the housing 22 and fixed. At this time, the housing 22 is formed so that the other side of the winding spring 156 is firmly fixed, the insertion groove 22b in which the other side of the winding spring 156 is inserted in a circular direction as shown in the enlarged direction is formed along the circumferential direction desirable.

Referring to FIG. 4, when the external temperature rises, that is, the temperature of the roof increases, the wax 24 of the driving member 20 expands, the slider as shown in FIG. 40 moves (rises) along the rod R. As shown in FIG. Of course, the slider 40 is generated as the pressurized oil 28 presses the rod R while the diaphragm 26 expands and deforms due to the expansion of the wax 24 as shown in FIG. The cylinder 42 is raised by the reaction force. At this time, the cylinder 42 is raised together with the drive member 20 as shown. Of course, the drive member 20 rises to the top of the case 10 as shown.

Slider 40 ascends and pulls up and down switch 50 as shown in enlargement " bar ". That is, the cylinder 42 raises the shielding sleeve 52 of the switchgear 50 while raising. At this time, the cylinder 42 pulls up the shielding sleeve 52 as the protruding pin 46a is caught by the penetrating means 46b of the shielding sleeve 52. That is, the protruding pin 46a raises the shielding sleeve 52 while being caught by the penetrating means 46b.

On the other hand, the valve member 54 is raised together with the shielding sleeve 52 as shown in the enlarged view "bar". Of course, the valve member 54 opens the valve seat VS while being spaced apart from the valve seat VS G2 as shown in an enlarged view. Therefore, the valve member 54 opens by communicating the bypass flow path BP of the refracted shape as shown in an enlarged manner.

Thus, when the bypass flow path BP is opened, the bypass of the connection pipe 132 on the right side of the drawing centers on the blocking wall 132a of the intermittent valve 130 as shown in the enlarged view "g." Cooling water embedded in the flow path BP is supplied to the bypass flow path BP through the communication hole 134a of the diaphragm 134. In addition, the cooling water filled in the chamber 138a of the case 138 is also discharged through the bypass flow path BP. At this time, the bypass flow path BP side and the chamber 138a of the connection pipe 132 are reduced in the water pressure as the coolant is discharged through the bypass flow path BP. Accordingly, the coolant filled in the left side of the drawing centers on the blocking wall 132a of the connecting pipe 132 so as to overflow the blocking wall 132a while raising the diaphragm 134 as shown by the hydraulic pressure. It is supplied to the branch pipe 120 through). Of course, the coil spring 136a embedded in the chamber 138a is compressed.

Here, the rod R described above is not lowered when the support protrusion 32 is supported by the step of the case 10, as shown in the enlarged view "e" when pressed by the drive member 20. That is, the rod R is prevented from moving by the support protrusion 32. The support protrusion 32 forms a state accommodated in the receiving groove 34 formed in the shielding sleeve 52 of the switchgear 50 when the switchgear 50 rises by the slider 40. That is, as the support protrusion 32 is accommodated in the receiving groove 34, the contact with the shielding sleeve 52 is prevented. Therefore, the support protrusion 32 does not prevent the movement of the shielding sleeve 52.

On the other hand, when the driving member 20 is cooled by the cooling water injected from the nozzle 122 of the branch pipe 120 described above, the pressure of the rod R is stopped as the wax 24 therein contracts. Accordingly, the cylinder 42 of the slider 40 returns to its original position along with the switch 50 as shown in FIG. 3 described above by the elastic force of the elastic body SP that presses the switch 50.

At this time, the valve member 54 closes the bypass flow path BP by shielding the valve seat VS as shown in FIG. 3. Accordingly, the coolant filled in the chamber 138a of the case 138 through the communication hole 134a of the diaphragm 134 through the blocking wall 132a is not discharged to the bypass flow path BP, but the chamber ( The diaphragm 134 is pressed downward together with the coil spring 136a while being filled in the 138a. Accordingly, the diaphragm 134 again shields the bypass hole 132b located above the blocking wall 132a in a watertight state as shown in FIG. 3.

On the other hand, since the shielding sleeve 52 is lifted and lowered by the traction of the protruding pin 46a on which the other end is caught by the penetrating means 46b as described above, the enlarged view as shown in "bar". Likewise, the opening and closing time is determined by the diameter D of the penetrating means 46b. That is, when the diameter D of the through means 46b is large, the switch 50 is towed by the protruding pin 46a only after a certain time has elapsed after the protruding pin 46a of the slider 40 is raised. Is raised. On the contrary, when the diameter D of the penetrating means 46b is made small, the switch 50 is raised at the same time as the slider 40 as the protruding pin 46a is immediately caught on the upper end of the penetrating means 46b. can do. Therefore, the opening and closing time of the switch 50 is determined by the diameter D of the penetrating means 46b.

Here, the opening and closing time described above may mean the expansion temperature of the wax 24 filled in the driving member 20. In other words, when the diameter D of the penetrating means 46b is largely formed, the wax 24 is heated until the temperature becomes higher because the switch 50 rises later. This is because the wax 24 is heated to a higher temperature because the above-described nozzle 122 of the branch pipe 120 sprays cooling water late as the switch 50 rises late. However, when the diameter of the penetrating means 46b is small, the wax 24 rises quickly, so that the nozzle 122 sprays the cooling water more quickly, so that the wax 24 is heated to a lower temperature and then cooled again. Thus, the diameter of the penetrating means 46b can be used to adjust the heating temperature of the wax 24.

Meanwhile, when the valve cooling member 150 is provided as shown in the drawing, the wax 24 may be easily cooled by the coolant injected from the bypass tube 152 of the valve cooling member 150. When the valve cooling member 150 is provided with a winding spring 156 of the distance retention zone as shown, the coolant 150 always sprays the coolant to the driving member 20 regardless of external factors such as wind.

On the other hand, the above-mentioned heat collecting plate 60 needs to further include an area expansion means for expanding the area in order to improve the heat collecting performance. That is, when the area of the heat collecting plate 60 is expanded, the heat collecting performance is improved. The area expansion means may be configured to form a bend 62 in the heat collecting plate 60 as shown, for example, so that the cross-sectional area of the heat collecting plate 60 is extended by the bend 62. At this time, the above-described bend 62 is preferably formed by forming an embossing on the heat collecting plate 60 as shown.

On the other hand, Figure 5 is a longitudinal cross-sectional view showing another embodiment of the thermosensitive valve of the valve device shown in Figure 2, Figure 6 is a longitudinal section showing the opening operation of the thermosensitive valve shown in Figure 5 7 is a longitudinal cross-sectional view showing the closing operation of the thermosensitive valve shown in FIG. The thermosensitive valve according to another embodiment is configured as shown in the above-described switchgear 50 is different from the above-described thermosensitive valve. Accordingly, only these differences will be described with reference to the accompanying drawings.

Referring to FIG. 5, a thermosensitive valve according to another embodiment may include, as illustrated, a switch 50 having a through sleeve 55 penetrated at both ends thereof, for example; Stopper 56; Block 57; Auxiliary elastomer (SP2); A fixing member 58; The valve member 54; is configured to include. Referring to the components of the switch 50 in more detail as follows.

As shown in the through sleeve 55, one end is connected to the cylinder 42 of the slider 40 by a protruding pin 46a. The through sleeve 55 moves together with the slider 40 along the outer circumferential surface of the rod R embedded in the case 10 when the cylinder 42 rises. The through sleeve 55 is elastically supported by the elastic body SP embedded in the case 10 as shown.

The stopper 56 is formed in the form of a cylindrical protrusion as shown. The stopper 56 is mounted on one side of the inner circumferential surface of the through-sleeve 55 as shown and is fixed in a state protruding toward the other side of the inner circumferential surface of the through-sleeve 55. As shown in the drawing, the stopper 56 may be fixed to the inner side of the through sleeve 55 by fitting one end to an inner circumferential surface of a ring embedded in the through sleeve 55.

Block 57 is built in the other side of the inner circumferential surface of the through-sleeve 55 to form a state spaced apart from the stopper 56. The block 57 is detachably fixed to the inner circumferential surface of the through sleeve 55 by the fixing member 58 to be described later. Therefore, the block 57 moves together with the through sleeve 55 when the through sleeve 55 moves.

Secondary elastic material (SP2) is embedded in the through sleeve 55, as shown in the elastic support for the block (57). As shown in FIG. 2, the auxiliary elastic body SP2 is preferably configured such that both ends thereof are respectively fixed to the stopper 56 and a part of the block 57.

The fixing member 58 detachably fixes the block 57 to the inner circumferential surface of the through sleeve 55 as described above. Of course, the fixing member 58 detachably fixes the block 57 at a predetermined position inside the through sleeve 55. That is, the block 57 is fixed at the set position of the through sleeve 55 by the fixing member 58 or separated at the set position.

The fixing member 58 may include, for example, an inner spring 58a embedded in the block 57 to provide an elastic force; A plurality of spherical bodies 58b protruding to both sides of the block 57 while being elastically supported at both ends of the inner spring 58a; It may be configured to include; the receiving means (58c) of the groove shape is formed on the other side of the inner circumferential surface of the above-described through sleeve 55, the spherical body (58b) protruding to both sides of the block 57 is accommodated. That is, the fixing member 58 includes an inner spring 58a; Spherical body 58b; It may be configured to include; receiving means (58c).

Here, the above-described spherical body 58b may be a full spherical ball as shown, or alternatively, only the outside may be a hemispherical ball formed in a spherical shape. In addition, the above-described receiving means 58c is formed along the circumferential direction on the inner circumferential surface of the through sleeve 55. The receiving means 58c is preferably formed with the inclined surface 58c 'as shown in the enlarged view so that the spherical body 58b is easily separated to the lower end.

On the other hand, the valve member 54 described above is coupled to the lower end of the block 57 as shown, and opens and closes the valve seat VS by the movement of the block 57. This valve member 54 is configured identically to the valve member 54 of FIGS. 3 and 4 described above as shown. That is, the valve member 54 is composed of a fixture 54a and a sealing film 54b.

In the thermally sensitive valve according to another embodiment configured as described above, the opening and closing time of the switch 50 is determined by the distance between the stopper 56 and the block 57. This will be described later.

 When the wax 24 of the driving member 20 is not heated to the set temperature, the thermosensitive valve according to another embodiment maintains the valve member 54 by lowering the switch 50 as shown in the drawing. Close the valve seat VS.

Referring to FIG. 6, the thermosensitive valve according to another embodiment is illustrated by the reaction force generated by the rod R when the wax of the driving member is heated to press the rod R by the driving member. Likewise, the cylinder 42 is raised. At this time, the cylinder 42 is spaced apart (ΔH) from the end of the rod (R) as shown.

The cylinder 42 ascends and ascends while pulling the through sleeve 55 fixed to the protruding pin 46a as shown. Of course, the through sleeve 55 rises with the cylinder 42. At this time, the stopper 56 is fixed in its original position as the rod R is not moved. However, the block 57 rises together with the through sleeve 55 because the spherical body 58b of the fixing member 58 is caught by the receiving means 58c of the through sleeve 55 as shown.

Block 57 rises with valve member 54 as shown. Thus, the valve member 54 opens the valve seat VS as shown. Therefore, the intermittent valve 130 described above supplies cooling water to the branch pipe 120 (see FIG. 3).

Block 57 stops rising as the top contacts the stopper 56 as shown. At this time, the through sleeve 55 continues to rise by the cylinder 42.

Referring to FIG. 7, the spherical body 58b of the fixing member 58 is a block having the inner spring 58a embedded therein while compressing the inner spring 58a as the through sleeve 55 continuously rises. It is inserted into the interior of the 57. Therefore, the state in which the block 57 is fixed to the inner circumferential surface of the through sleeve 55 is released. At this time, the block 57 is lowered as shown by the elastic force of the secondary elastic body SP2. That is, the block 57 descends while the through sleeve 55 is raised. Of course, the valve member 54 again closes the valve seat VS as shown.

The block 57 is in late contact with the stopper 56 when the distance G3 from the stopper 56 is far. On the contrary, the block 57 is quickly in contact with the stopper 56 when the distance G3 from the stopper 56 is close. That is, the block 57 is returned to the original position later when the separation distance G3 is far, and quickly returns to the original position when the separation distance G3 is close. Therefore, the valve seat VS closes late when the separation distance G3 is far, and closes quickly when the separation distance G3 is near. In conclusion, the opening and closing time of the valve seat VS may be adjusted through the aforementioned separation distance G3.

In the mechanically controlled fluid injection system according to the embodiment of the present invention as described above, since the thermosensitive valve 140 is driven at a temperature set by the expansion force of the wax 24 filled in the driving member 20, the power supply is turned on. There is no need to automatically operate according to the outside temperature. Of course, since the power supply is not required, the wire piping and piping construction time can be shortened, and furthermore, the controller for controlling the valve can be omitted. That is, since the thermosensitive valve is operated non-electrically, there is an effect that can operate in a non-powered state.

In addition, since the cooling water can be automatically sprayed on the roof according to the external temperature, not only can the electric charge be greatly saved, but the solar energy can be efficiently used.

In addition, when the valve cooling member 150 is provided, the thermosensitive valve 140 may be accurately cooled, and thus, the roof may be partially prevented from being overheated as the valve is not cooled as in the prior art. There is also.

Since the above embodiments are merely illustrative of preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
