Description of the invention (1) [Industry use field] The present invention is related to, for example, as a priming water when starting a fire pump (fire pump device) water) The vacuum pump used in the device prevents water from flowing into the used water stop valve. [Conventional technology] Turbine pumps are generally used as fire pumps for various reasons * »Although this type of turbine pump has many advantages, its lack of viscosity is that when starting, the casing and the suction pipe must be The priming operation exposed to full water, therefore, most of the priming water injection devices have vacuum pumps. Although there are various types of such vacuum pumps, they are generally used as eccentric vane type rotary pump β because they require small size and good performance for fire fighting. As such vacuum pumps, in order to eliminate road pollution caused by lubricating oil For the sake of generality, the oil circulation type and the oilless type are generally used. However, in the fire pump device, when the water injection is started by the vacuum pump, water from the fire pump and the like will flow into the vacuum pump at the initial stage of the start of the water injection. As if water flows into the vacuum pump, the oil circulation type vacuum pump or If there is no oil-feeding vacuum pump, all kinds of bad photos will occur. That is, in the oil circulation type vacuum pump, there is a problem that the oil and water are mixed in the vacuum pump to become an emulsified state. In the oilless type vacuum pump, the impeller is fragile because of the self-lubricating material, such as the manufacture of a master, etc. Then the second round may be damaged due to the rush of water. Therefore, in order to prevent the water from flowing into the vacuum pump after the injection of the starting water for the fire pump is completed, it is generally at -3- (please read the precautions on the back and then write this page).

Description of the invention (2) Suction pipe connected to the fire pump A water stop valve is installed halfway with the suction pipe of the vacuum pump. ”It is known that this type of water stop valve is shown in Figure 2, for example, a diaphragm (diaphrag in) ⑶ is inserted between the valve body ⑴ and the upper cover ⑵, and the This diaphragm (3) is connected to the opening / closing valve (4) that opens and closes the valve hole (4) formed in the valve body (1) through a movable rod (7). When the vacuum pump operates, the air in the valve body (1) becomes a vacuum state by the exhaust of the vacuum pump. The diaphragm ⑶ is attracted to the bottom, and the opening and closing valve ⑸ is also lowered to the lower side through the movable guard ⑹, and the valve hole ⑷ is opened. As a result, the air in the fire pump is also exhausted by the vacuum pump and becomes a vacuum state, so the water is sucked from the water source. It is like this. When the water is repeatedly injected into the fire pump, the water will flow from the fire pump into the vacuum pump. However, due to the pressure of water, the on-off valve ⑸ rises and the sluice closes the hole ⑷, so water is prevented from flowing into the vacuum pump. [Problems to be Solved by the Invention] However, if the vacuum pump is stopped in the structure of the above-mentioned water stop valve, the air will flow back to the fire pump and the water may flow back. At the same time, the water may flow into the vacuum pump according to the water pumping state. Therefore, in the conventional water stop valve, it is necessary to additionally install a check valve to prevent the air from flowing back to the fire pump, and an attached buoy I barrel tank that retains water leaking from the water stop valve, therefore, to prevent water from flowing into the vacuum pump. It becomes large, and not only the piping becomes complicated and the water lifting time will be slow, at the same time, according to the stop time of the vacuum pump, the tank with the float will quickly become the defect of the full tank (please read the precautions on the back and fill in this page first).

Description of the invention (3) Therefore, the purpose of the present invention is to provide a water stop valve that solves the above problems ( Please read the precautions on the back before filling in this page) Ο [Solution of the present invention] The present invention is like a water stop valve. For the purpose of achieving the above purpose, it has: Install the flow in the lower part The inlet is provided with an outlet in the upper part, and the valve body formed by forming a communication port connecting the inverted primary chamber of the inlet and the secondary chamber on the outlet side is installed in the primary chamber so as to be able to rise and fall to open and close the above communication The opening and closing valve of the hole is formed of a ball valve installed in the secondary chamber for opening and closing the communication port, and a buoy connected to the opening and closing valve in the secondary chamber. When the opening and closing valve closes the communication port with the opening and closing valve , Formed to interfere with the ball valve nested at the upper end of the communication port. [Function] According to the water stop valve according to the present invention, when the start of water injection is completed, the buoyancy of the water flowing in from the water outlet, or the water pressure buoy is pushed up, and the opening and closing valve will block the opening. After that, if the vacuum pump is stopped, it immediately sucks in air from the outflow port and presses the ball valve against the communication port with its air pressure to block it. [Embodiment] Η According to the diagram, an embodiment of the present invention is described below. Printed in the first figure of the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs, (11) the valve body, this embodiment is composed of the lower valve on the side of the primary chamber The body (12) is composed of the upper valve body (13) on the secondary chamber side. The lower valve body (12) is provided with an inflow port (14) at the lower part, and an opening / closing valve (23) to be described later is provided at the upper part to support the supporting member (15) that can be lifted up and down freely. Due to the 03 Xuanxm (CNS) Ψ4 specification (210x297 male bitch) A 6 B6 205088 V. Description of the invention (4) is integrated, and an appropriate number of openings are formed in the support member (15) (please read the notes on the back first (Fill in this page again) (16), (16) ... The upper valve body (13) is provided with an outflow port (17) at the side, and a lower part is provided with a flow port (18) communicating the outflow port (17) and the inflow port (14) of the lower valve body (12) . (19) Ye installs the valve cover on the upper part of the upper valve body (13), installs the hanging guide cylinder part (20) in the upper valve body (13), installs the ball valve (21), and connects the ball valve (21) 21) Nested on an elastic ring (22) installed at the upper end periphery of the upper valve body (13) communication port (18). (23) The supporting member (15) of the lower valve body (12) is supported by the valve shaft (24) to open and close the valve freely ascending and descending, and the buoy Λ installed at the lower end of the valve shaft (2 4) is used The lowering action opens and closes the communication (25) port (18) of the upper valve body (13) and the lower end periphery. The upper surface (23a) of the on-off valve (23) is formed into a conical shape so that when the on-off valve (23) blocks the communication port (18) of the upper valve body (13) and nested on the upper end of the communication port (18) The ball valve (21) on the elastic ring (22) on the periphery is dry, so that the above-mentioned communication port (1 8) and the ball valve (2 1) will not be blocked at the same time. The pseudo structure of the water stop valve of the present invention is as described above, Η describes its operation as follows Ο Printed by the Employee Consumer Cooperative of the Bureau of Standards and Economics of the Ministry of Economic Affairs. The part (20) is attracted and moved upward to open the communication port (18) of the upper valve body (13), and the air in the fire pump and suction pipe flows through the inlet (14) and the opening (16) (16). .... The communication port (18) and the outflow port (17) are sucked into the vacuum pump and the exhaust and decompression fire-fighting pump and the inside of the suction pipe. In this way, since the fire pump will become a vacuum state, the fire pump will be set from 隯?

Description of invention (5) Water is sucked from the water source, and the starting water of the anti-use pump is injected. Similarly, when the starting water injection is completed for the fire pump, the water flows into the lower valve body (12) from the fire pump, so the buoy (25) is pushed up by the buoyancy of the water or the water pressure And the opening and closing valve (23) is also pushed upward through the valve shaft (24) to block the communication port (18) to prevent water from flowing into the vacuum pump. Thereafter, if the vacuum pump is stopped, at the instant, air is sucked into the upper valve body (13) from the outlet (17), whereby the air directs the ball valve (21) toward the elastic ring installed at the upper periphery of the communication hole (18) (22) Pressing strongly, this time, instead of the on-off valve (23), the ball valve (21) blocks the communication hole (18). By this, even if the vacuum pump is stopped, the air can be prevented from flowing back to the fire pump, so the water of the fire pump can be prevented from flowing backward. 》 If the water stop valve according to the present invention not only has the function of a water stop valve, but the opening and closing valve (23) will block the communication port (18) due to the buoyancy of the water, or the buoy (25) is pushed up by the water pressure, so it can be It completely prevents the backflow of air to the fire pump, and can completely prevent the inflow of water to the vacuum pump. As a result, it is not necessary to add a check valve and a tank with a buoy, as is conventional, so that the form of the device for preventing water from flowing into the vacuum pump becomes small, and there is no need for complicated piping or the like. However, when using an oilless vacuum pump, in order to prevent the vacuum pump from sucking in garbage or dust, although it is necessary to attach a barrel with an air filter, this barrel with an air filter is very small compared with the conventional buoy barrel. It is not a hindrance to the miniaturization of the form. Also, as the water stop valve according to the present invention, since the communication port (18) is formed so as not to be blocked by the ball valve (21) and the on-off valve (23) at the same time, so (please read the precautions on the back before filling in this Page) 装 · Order _ line < Taizhang Zhang Η 疳 1Λ is determined by Ψ: 搮 rniCNS) A 4 media grid (21〇y 297 public you 0 205088 A 6 B6 printed by the Ministry of Economic Affairs, Bureau of Standards, employee elimination cooperatives V. Description of the invention (6) The inside of the communication port (18) does not become a vacuum state, and the opening and closing valve (23) can perform normal action β. That is, the communication port (18) is provided by the ball valve (21) and the opening and closing threshold (23) At the same time, the inside of the communication port (18) becomes a vacuum state, so that the water in the lower valve body (12) disappears, and the opening and closing valve (23) blocks the communication port (18) due to the vacuum, so it has After that, even if the vacuum pump is started, the air cannot be sucked in. According to this embodiment, although the valve body (11) is a divided structure of the lower valve body (12) and the upper valve body (13), the present invention is not limited to Therefore, it can also be an integrated structure. In this embodiment, the opening / closing valve (23) has its valve shaft (24) The supporting member (15) of the lower valve valve (12) slides freely to support up and down freely, but the valve shaft (24) of the opening and closing valve (23) can also be installed integrally on the diaphragm by The diaphragm can be lifted and lowered freely. If the on-off valve (23) is supported by the diaphragm lifted and lowered freely because there is no sliding part, there are few failures. Furthermore, in this embodiment, the ball valve (21) is pushed against the installation The elastic ring (22) at the upper edge of the communication hole (18) blocks the communication port (18), but the ball valve Λ can also be directly pressed against the upper edge of the communication port (18) (21) to block the communication port ( 18).
