Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a container valve that can be started and stopped multiple times. Background Technology
[0002] With the transformation of the global energy structure and the rapid development of new energy technologies, energy storage power stations, as an important means of balancing power supply and demand and improving grid flexibility, are seeing their construction scale and application scope continuously expand. However, the safety issues of energy storage power stations, especially fire risks, are receiving increasing attention. Therefore, the demand for energy storage fire protection systems, as key facilities to ensure the safe operation of energy storage power stations, is expected to show a significant growth trend in the next three years. This paper forecasts and analyzes the demand for energy storage fire protection systems in the next three years from multiple perspectives. The carbon monoxide and smoke / temperature composite fire detection device for energy storage power stations is mainly used for monitoring thermal runaway in energy storage compartments. It is used in conjunction with the fire alarm control device produced by our company. This detector monitors changes in carbon monoxide, smoke, and temperature in the environment, performs data analysis, and determines whether battery thermal runaway has occurred. This allows for timely detection of early fires and transmission to the fire alarm control device for response, preventing the expansion and spread of battery thermal runaway. Existing container valves can only release extinguishing agents once, and cannot suppress secondary fires in the event of reignition. Utility Model Content

[0007] Preferably, the top of the valve core is in close contact with the bottom of the pressure ring, and the large spring is disposed between the valve core and the pressure ring.
[0008] Preferably, both the pressure ring and the valve core have a sealing ring nested on their outer walls, and the pressure ring and the valve core move vertically up and down in the channel inside the valve body.
[0009] Preferably, a connection port is provided at the lower front end of the valve body, the connection port is connected to the lower part of the channel inside the valve body, and the valve core covers the rear end of the connection port.

[0016] Legend:
[0017] Valve body 1, valve cover 2, piston 201, small spring 202, valve core 3, large spring 301, pressure ring 4, safety screw 5, safety diaphragm 501, gasket 502, pressure gauge switch nut 503. Detailed Implementation
[0018] Example 1, referring to Figure 1-4 A container valve capable of multiple starts and stops includes a valve body 1, characterized in that a valve cover 2 is fixed to the top of the valve body 1, a live body 201 is embedded in the middle of the valve cover 2, a small spring 202 is connected to the bottom of the live body 201, a valve core 3 is embedded in the middle of the valve body 1, a large spring 301 is embedded in the middle of the valve core 3, a pressure ring 4 is embedded in the upper part of the inside of the valve body 1, a safety screw 5, a safety diaphragm 501 and a gasket 502 are embedded in the lower left side of the valve body 1, and a pressure gauge switch nut 503 is nested at the rear end of the valve body 1.
[0019] The bottom end of the small spring 202 is embedded in the upper part of the inside of the pressure ring 4, and the small spring 202 is located between the bottom of the living body 201 and the top of the pressure ring 4.
[0020] The top of the valve core 3 is close to the bottom of the pressure ring 4, and the large spring 301 is disposed between the valve core 3 and the pressure ring 4;
[0021] Both the outer walls of the pressure ring 4 and the valve core 3 are nested with sealing rings, and the pressure ring 4 and the valve core 3 move vertically up and down in the channel inside the valve body 1.
[0022] When the electric detonator receives a start signal, the electric detonator in the device is triggered, causing an explosion or rapid chemical reaction that generates a powerful impact or pressure wave. This impact or pressure wave acts on the valve core 3, causing it to overcome the sealing force and resistance, and move rapidly to compress the large spring 301 and small spring 202, opening the connection port of the container valve. This allows the extinguishing agent inside the container to be rapidly sprayed out through the connection port under pressure. Afterward, the large spring 301 and small spring 202 return to their original positions, pushing the valve core 3 downward to seal the connection port, preventing further spraying of extinguishing agent. When the electric detonator receives another start signal, the valve core 3 moves upward again, allowing for multiple sprays of the extinguishing agent, effectively suppressing the reignition of the fire.
[0023] A connection port is provided at the lower front end of the valve body 1, which is connected to the lower part of the channel inside the valve body 1. The valve core 3 covers the rear end of the connection port.
[0024] After the valve core 3 moves upward in the valve body 1, the valve core 3 no longer blocks the connection port, allowing the extinguishing agent to spray out from the connection port at the front end.
[0025] The main function of the pressure gauge switch nut 6 is to control the pressure measurement path. By rotating the pressure gauge switch nut 6, the communication channel between the pressure gauge and the medium inside the container can be opened or closed. When it is necessary to measure the pressure inside the container, loosen the switch nut to open the passage, allowing the medium inside the container to enter the pressure gauge, and the pressure gauge can display the pressure value. After the measurement is completed or when it is not necessary to observe the pressure, tighten the pressure gauge switch nut 6 to cut off the passage, prevent the medium from continuously acting on the pressure gauge, protect the pressure gauge, and avoid possible leakage.
[0026] Example 2 differs from Example 1 in that, in this example, a connection port that communicates with the lower left side of the valve body 1 is provided horizontally, and a safety screw 5 is embedded in the bottom left side of the valve core 3. The safety screw 5, the safety diaphragm 501, and the gasket 502 are arranged from left to right in the connection port of the valve body 1.
[0027] The main function of the safety screw 5 is to ensure that when the valve body 1 is under high pressure, the extinguishing agent and other media will not leak from these connections, thus ensuring the sealing and integrity of the system. At the same time, the safety screw 5 can be used with some pressure balancing channels or small holes. When the pressure inside the valve body 1 changes, the pressure is reasonably transmitted and balanced between different chambers or parts through the channels controlled by the safety screw 5, preventing local pressure from being too high or too low, and ensuring the stable operation of the container valve.
[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
