Description

Technical Field

[0001] The utility model relates to the technical field of deluge valves, and more specifically, to a pneumatically controlled deluge valve skid. Background Art

[0002] The fire water deluge valve skid is the main equipment for spraying seawater, mainly responsible for isolating and conducting the pressurized fire water loop and the fire water protection area. Under normal conditions, the main valve of the deluge skid (i.e., the deluge valve) is closed to ensure the standby pressure of the fire water loop. When a fire occurs in a certain area, the deluge valve in the corresponding area will be automatically started and opened to conduct the fire area and the fire water loop, and guide the fire water to the fire area for fire extinguishing.

[0003] The inventor has found through research that when a fire occurs, in the case of a burned-out cable or other power failure, the deluge valve cannot be automatically opened, and manual emergency opening needs to be carried out by the staff in front of the deluge valve skid. For offshore platforms, it is inconvenient for the staff to move back and forth between different platforms to open the valve. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pneumatically controlled deluge valve skid, which can automatically open the deluge valve under power failure and solve the problem of inconvenient movement of offshore personnel.

[0007] A deluge valve, which is connected with a spray water inlet pipe and a spray water outlet pipe. A diaphragm and a valve seat are arranged inside the deluge valve. The diaphragm can selectively abut against the valve seat. When the diaphragm abuts against the valve seat, the spray water inlet pipe and the spray water outlet pipe are cut off. When the diaphragm is separated from the valve seat, the spray water inlet pipe and the spray water outlet pipe are communicated. One end of the diaphragm away from the valve seat is provided with a diaphragm chamber. A pressure water inlet and a pressure water outlet communicated with the diaphragm chamber are arranged on the deluge valve;

[0008] A pneumatic pilot valve, which is provided with an air inlet, a drain water inlet and a drain water outlet. The air inlet is connected with an air inlet pipe.

The air inlet is provided on the pneumatic valve cover, and the drain inlet and the drain outlet are provided on the pneumatic valve body. The valve core is movably arranged between the pneumatic valve body and the pneumatic valve cover. When high-pressure gas is introduced into the air inlet, the valve core moves towards the drain inlet to block the drain inlet and the drain outlet.

[0013] In an alternative embodiment, the solenoid valve includes a pressure air inlet, a pressure air outlet, and a vent port. The pressure air inlet is used for introducing high-pressure gas.

[0033] Please refer toFigure 1 and Figure 2 , this embodiment provides a pneumatically controlled deluge valve skid 100, which includes a deluge valve 10, a pneumatic pilot valve 20, and an electromagnetic valve 30.

[0034] The two ends of the deluge valve 10 are connected with a spray water inlet pipe 11 and a spray water outlet pipe 12. A diaphragm 13 and a valve seat 14 are arranged inside the deluge valve 10. The diaphragm 13 can selectively abut against the valve seat 14. The diaphragm 13 abuts against the valve seat 14 to cut off the spray water inlet pipe 11 and the spray water outlet pipe 12. The diaphragm 13 is separated from the valve seat 14 to connect the spray water inlet pipe 11 and the spray water outlet pipe 12. One end of the diaphragm 13 away from the valve seat 14 is provided with a diaphragm cavity 131. The deluge valve 10 is provided with a pressure water inlet 132 and a pressure water outlet 133 communicated with the diaphragm cavity 131. It can be understood that the spray water inlet pipe 11 is used to introduce the spray water source. The spray water outlet is used for spraying water to extinguish fires. Spraying is carried out when the deluge valve 10 is opened, and spraying stops when the deluge valve 10 is closed. The pressure water inlet 132 is used to introduce pressure water into the diaphragm cavity 131 to increase the pressure in the diaphragm cavity 131. The pressure water outlet 133 is used to discharge the pressure water in the diaphragm cavity 131 to reduce the pressure in the diaphragm cavity 131. When the pressure in the diaphragm cavity 131 increases, the diaphragm 13 moves downward and abuts against the valve seat 14 to close the deluge valve 10; when the pressure in the diaphragm cavity 131 decreases, the pressure in the spray water inlet pipe 11 is greater than the pressure in the diaphragm cavity 131, and the diaphragm cavity 131 moves upward under the action of the water pressure and is separated from the valve seat 14 to open the deluge valve 10.

[0035] Please refer to Figure 3 , the pneumatic pilot valve 20 is provided with an air inlet 21, a drain water inlet 22, and a drain water outlet 23. The air inlet 21 is connected with an air inlet pipe 27. The drain water inlet 22 is communicated with the pressure water outlet 133. The drain water inlet 22 and the drain water outlet 23 can be selectively communicated or cut off. When high-pressure gas is introduced into the air inlet 21, the drain water inlet 22 and the drain water outlet 23 are cut off. When the introduction of high-pressure gas into the air inlet 21 stops, the drain water inlet 22 and the drain water outlet 23 are communicated. It can be understood that when the drain water inlet 22 and the drain water outlet 23 are communicated, the pressure water in the diaphragm cavity 131 is discharged successively through the pressure water outlet 133, the drain water inlet 22, and the drain water outlet 23, and the pressure in the diaphragm cavity 131 decreases. When the pressure in the spray water inlet pipe 11 is greater than the pressure in the diaphragm cavity 131, the water in the spray water inlet pipe 11 flushes open the diaphragm 13, so that the diaphragm 13 is separated from the valve seat 14 to open the deluge valve 10. When the drain water inlet 22 and the drain water outlet 23 are cut off, the pressure water in the diaphragm cavity 131 cannot be discharged from the pressure water outlet 133. As the pressure water inlet 132 continuously inputs pressure water into the diaphragm cavity 131, the pressure in the diaphragm cavity 131 gradually increases, so that the diaphragm 13 abuts against the valve seat 14 below to close the deluge valve 10.

[0036] Please continue to refer toFigure 1 and Figure 2 , a solenoid valve 30 is arranged on the air inlet pipe 27 and is used to cut off or communicate with the air inlet pipe 27. It can be understood that when the solenoid valve 30 is opened, high-pressure gas can be input into the pneumatic pilot valve 20, so that the water discharge inlet 22 and the water discharge outlet 23 are cut off, and the deluge valve 10 is closed; when the solenoid valve 30 is closed, the pneumatic pilot valve 20 is depressurized, and the water discharge inlet 22 and the water discharge outlet 23 are opened under the action of the pressurized water in the diaphragm cavity 131, so that the water discharge is quickly communicated with the water discharge outlet 23, and the deluge valve 10 is opened.

[0037] Further, the solenoid valve 30 is a power-off open solenoid valve 30. It can be understood that the power-off open solenoid valve 30 means that only when the power is cut off or the power supply is lost, the electromagnet can open the valve. Its working principle is that when the power supply is normal, the electromagnet closes the valve; when a power failure occurs, the electromagnet loses its magnetic force and the valve opens automatically. This design can ensure that the fire-fighting equipment can be started normally in case of a power supply failure or power cut, effectively protecting people's lives and property safety.

[0038] The solenoid valve 30 is also provided with a manual reset button. Only when people arrive at the scene can the solenoid valve 30 be closed, which can ensure that the deluge valve 10 remains open during fire extinguishing, and the relative safety is better.

[0039] Specifically, in this embodiment, the deluge valve 10 further includes a deluge valve body 15 and a deluge valve cover 16. The deluge valve body 15, the diaphragm 13 and the deluge valve cover 16 are sequentially fixedly connected by bolts. A diaphragm cavity 131 is formed between the diaphragm 13 and the deluge valve cover 16. Further, in order to facilitate the reset of the diaphragm 13, an elastic member 17 is also arranged between the diaphragm 13 and the deluge valve cover 16. In this embodiment, the elastic member 17 is a spring. A spring seat is also arranged on the diaphragm 13. The spring is sleeved on the spring seat.

[0040] Please refer to Figure 3。Further, the pneumatic pilot valve 20 includes a pneumatic valve body 26, a valve core 25, and a pneumatic valve cover 24. The pneumatic valve body 26 and the pneumatic valve cover 24 are fixedly connected by bolts. The air inlet 21 is provided on the pneumatic valve cover 24. The water discharge inlet 22 and the water discharge outlet 23 are provided on the pneumatic valve body 26. The valve core 25 is movably arranged between the pneumatic valve body 26 and the pneumatic valve cover 24. When high-pressure gas is introduced into the air inlet 21, the valve core 25 moves towards the water discharge inlet 22 to cut off the water discharge inlet 22 and the water discharge outlet 23. It can be understood that there is an air chamber between the valve core 25 and the pneumatic valve cover 24, and a water passage chamber between the valve core 25 and the pneumatic valve body 26. When high-pressure gas is introduced into the air inlet 21, it pushes the valve core 25 to move downward, so as to abut against the water discharge inlet 22 of the pneumatic valve body 26, block the water discharge inlet 22, and isolate the water discharge inlet 22 and the water discharge outlet 23. When the supply of high-pressure gas to the air inlet 21 stops and the pressure in the air chamber is less than the pressure at the water discharge inlet 22, the valve core 25 moves upward under the action of the pressurized water, so as to conduct the water discharge inlet 22, the water passage chamber, and the water discharge outlet 23, enabling the pressurized water in the diaphragm chamber 131 to be discharged.

[0041] Further, the solenoid valve 30 includes a pressure air inlet 31, a pressure air outlet 32, and a vent port 33. The pressure air inlet 31 is used to introduce high-pressure gas. The pressure air outlet 32 is communicated with the air inlet 21. The solenoid valve 30 is used to connect the pressure air inlet 31 and the pressure air outlet 32, or connect the pressure air inlet 31 and the vent port 33. It can be understood that when the solenoid valve 30 is opened, the pressure air inlet 31 and the pressure air outlet 32 are communicated, and high-pressure gas is introduced into the pneumatic pilot valve 20; when the solenoid valve 30 is closed, the pressure air inlet 31 and the vent port 33 are connected, and the high-pressure gas is discharged from the vent port 33.

[0042] In this embodiment, a pressure regulating valve 34 is further provided on the air inlet pipe 27 for regulating the air pressure in the air inlet pipe 27. A pressure gauge 35 is also provided on the air inlet pipe 27 for detecting the air pressure in the air inlet pipe 27 to prevent the air pressure from being too high or too low.

[0043] Optionally, in this embodiment, the pressure water inlet 132 is connected to the spray inlet pipe 11. It can be understood that the pressurized water introduced into the diaphragm chamber 131 can be sourced from the spray water. In other embodiments, the pressure water inlet 132 can also be connected to an external pressure water source, as long as the pressure in the diaphragm chamber 131 can be ensured, and the present utility model is not limited thereto.

[0044] In this embodiment, the water discharge outlet 23 is connected to the spray outlet pipe 12. It can be understood that the pressurized water in the diaphragm chamber 131 can be used as spray water for fire extinguishing together, saving resources. In other embodiments, the water can also be directly discharged through the water discharge outlet 23, and the present utility model is not limited thereto.

[0045] Please refer toFigure 4 The pneumatically controlled deluge valve skid 100 further includes a skid frame 40 and a control panel 41. The deluge valve 10, the pneumatic pilot valve 20, the solenoid valve 30 and the control panel 41 are all fixed within the skid frame 40. The control panel 41 is used to display the working state of the pneumatically controlled deluge valve skid 100 and facilitate the staff to control the pneumatically controlled deluge valve skid 100.

[0046] The beneficial effects of the pneumatically controlled deluge valve skid 100 provided in this embodiment are as follows:

[0047] In this pneumatically controlled deluge valve skid 100, the pneumatic pilot valve 20 is provided to control the pressure change in the diaphragm chamber 131, conduct the drain inlet 22 and the drain outlet 23 to reduce the pressure in the diaphragm chamber 131, thereby opening the deluge valve 10; isolate the drain inlet 22 and the drain outlet 23, and the pressure in the diaphragm chamber 131 gradually increases, thereby closing the deluge valve 10. By providing the solenoid valve 30 to control the high-pressure gas input of the pneumatic pilot valve 20, the opening and closing of the deluge valve 10 are indirectly controlled. The solenoid valve 30 is a power-off open solenoid valve 30 and can be opened in the case of power failure. A manual reset button is provided, and only when someone arrives at the scene can the solenoid valve 30 be closed, which can ensure that the deluge valve 10 remains open continuously during fire extinguishing, and the relative safety is better. This pneumatically controlled deluge valve skid 100 can automatically open the deluge valve 10 in the case of power failure, ensure continuous fire extinguishing of the deluge valve 10, has good safety, and realizes remote control through the pneumatic pilot valve 20, solving the problem of inconvenient movement of offshore personnel.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
