The compatible through-hole of the body of rod is stated, the diameter of the boss is greater than the diameter of the through-hole, and the boss is located in the main valve body.
Preferably, the adjusting screw is hand screw.
By adopting the above technical scheme, due to the setting of temperature sensing glass ball, when so that fire occurs, temperature sensing glass ball is heated swollen
Swollen speed is fast, and then faster reaches broken degree, and spool is made to lose limitation, and then valve opening.Speed is responded with faster fire
Degree.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- valve body, 2- spool, 30- spring, 4- temperature sensing glass ball, 5- inlet, 6- liquid outlet, 7- adjust screw,
8- supporting pad, 9- ball sealer, 10- peep hole, 11- main valve body, 12- auxiliary valve body.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of fire resisting damper is equipped with valve chamber, sets in valve chamber including whole valve body 1 cylindrical in valve body 1
Spool 2, spring 3 and the temperature sensing glass ball 4 for having the axial direction along valve body 1 to be sequentially distributed, the both ends of spring 3 are separately connected spool
2 upper end, temperature sensing glass ball 4 lower end, in the present embodiment, spring 3 offsets with spool 2 and spring 3 with temperature sensing glass ball 4
It connects with easy disassembly；Be additionally provided with the inlet 5 and liquid outlet 6 being connected to valve chamber on valve body 1,2 free end of spool (i.e. lower end) with
Inlet 5 is adapted to block inlet 5, and 4 free end of temperature sensing glass ball (i.e. upper end) is connected on valve body 1.
Valve body 1 includes main valve body 11 and auxiliary valve body 12, and main valve body 11 is connected through a screw thread with auxiliary valve body 12, and inlet 5 goes out
Liquid mouth 6 is arranged on auxiliary valve body 12, and spool 2, spring 3 and temperature sensing glass ball 4 are arranged in main valve body 11.
In order to adjust cracking pressure, fire resisting damper is made to be applicable in different use environments, in the present embodiment, valve body 1 is connected with edge
The adjusting screw 7 of the axial direction setting of valve body 1, adjusting screw 7 is hand screw, and 4 free end of temperature sensing glass ball is connected to tune
It saves on screw 7.In use, adjusting the deflection of 7 adjustment spring 3 of screw by screwing, and then the pressure of the unlatching of control valve core 2
Power.
In the present embodiment, branch is equipped between temperature sensing glass ball 4 and spring 3, between temperature sensing glass ball 4 and adjusting screw 7
Stake pad 8, supporting pad 8 are cheated equipped with seat compatible with temperature sensing glass ball 4.The effect of supporting pad 8 is to increase movable part
Stability.
In the present embodiment, the ball sealer 9 of steel is equipped between inlet 5 and spool 2,9 diameter of ball sealer is greater than inlet 5
Diameter to prevent ball sealer 9 from falling.
For the ease of observation, and flame temperature is facilitated quickly to be transmitted on temperature sensing glass ball 4, in the present embodiment, main valve
Body 11 is equipped with peep hole 10.
Spool 2 is fallen completely in auxiliary valve body 12 in order to prevent, and in the present embodiment, spool 2 includes the body of rod and is connected to the body of rod
On boss, main valve body 11 is equipped with through-hole compatible with the body of rod, and the diameter of boss is greater than the diameter of through-hole, and boss is located at master
In valve body 11.The body of rod of spool 2 also acts as the effect of isolation main valve body 11 and auxiliary valve body 12 simultaneously, so that dust etc. is miscellaneous when closing valve
Object will not enter auxiliary valve body 12, and liquid will not enter main valve body 11 when also ensuring valve opening.
When a fire, flame enters valve body 1,4 expanded by heating of temperature sensing glass ball and fragmentation, spring by peep hole 10
3 lose support so that it is elongated, the elastic force that spool 2 receives becomes smaller, and causes spool 2 to be not enough to block inlet 5, to make inlet
