Description

Technical Field

[0001] The present application relates to the technical field of container valves, and in particular to an electric explosion type container valve. Background Art

[0002] Heptafluoropropane is a gaseous fire extinguishing agent, which is often used in electrical control cabinets. In order to improve the fire extinguishing effect and adapt to different occasions, heptafluoropropane needs to be used in combination with other gases, including nitrogen, inert gas, carbon dioxide gas, etc. In order to output the combination of two different fire extinguishing agents in the electrical control cabinet, a container valve is used.

[0003] A container valve in the related art includes a valve body, a first mounting groove is provided inside the valve body, a second mounting groove is provided on the bottom wall of the first mounting groove, a first feed inlet and a second feed inlet are provided on the valve body and communicate with the second mounting groove, and the first feed inlet and the second feed inlet are respectively connected to a fire extinguishing agent tank. A discharge port is provided on the valve body and communicates with the first mounting groove. A diaphragm is provided in the valve body for blocking the discharge end of the second mounting groove.

[0004] The valve body is provided with an electromagnetic drive device for puncturing the diaphragm, and the electromagnetic drive device includes an electromagnet mechanism, a release mechanism and an action mechanism. The electromagnet mechanism includes parts such as a coil, an iron core, and a yoke. The release mechanism includes parts such as a safety buckle handle and a slap button. The action mechanism includes parts such as a transmission device, a contact device, and a spring.

[0005] The driving force of the electromagnetic drive device is proportional to the volume of the electromagnetic drive device. The driving force of the existing electromagnetic drive device is relatively small. To puncture the diaphragm, the size of the internal parts of the electromagnetic drive device needs to be increased. The increase in the size of the parts increases the volume of the electromagnetic drive device, which results in a larger valve body volume that matches the electromagnetic drive device, that is, a larger container valve volume. In an electrical control cabinet with a small internal space, the container valve is difficult to install inside the electrical control cabinet, so it needs to be improved. Utility Model Content

[0006] In order to reduce the volume of the container valve, the present application provides an electric explosion type container valve.

[0007] The present application provides an electric explosion type container valve, which adopts the following technical solution:

[0008] An electric explosion type container valve comprises a valve body, a fixed cavity is provided in the valve body, a first fixed groove is provided at one end of the valve body, a second fixed groove connected with the fixed cavity is provided on the bottom wall of the first fixed groove, a discharge hole connected with the first fixed groove is provided on the side of the valve body, a diaphragm for blocking an opening of the fixed cavity close to the discharge hole is provided in the second fixed groove, a clamping piece for clamping the diaphragm is provided in the second fixed groove, an electric explosion driving structure for puncturing the diaphragm is provided on the valve body; the electric explosion driving structure comprises a shell, a mounting hole is provided on the side of the shell facing the fixed cavity, a push rod is passed through the mounting hole, and an electric explosion head for driving the push rod to extend out of the shell is provided in the shell.

[0009] By adopting the above technical scheme, the pressing part presses the diaphragm so that the diaphragm blocks the opening on one side of the fixed cavity, and prevents the fire extinguishing agent from being discharged from the discharge hole when there is no fire; when a fire occurs, the electric explosion head in the electric explosion drive structure generates explosive energy, and the explosive energy drives the push rod to move, so that the push rod diaphragm is punctured, so that the fire extinguishing agent can pass through the diaphragm and then be discharged from the discharge hole to achieve the fire extinguishing action; the electric explosion drive structure requires fewer internal components, and the overall structure is simple and compact. The electric explosion drive structure can be designed to be smaller in size, so as to adapt to a smaller valve body, so that the container valve can be used in an electrical control cabinet with a smaller internal space.

[0010] Optionally, the clamping member includes a first clamping ring threadedly connected to the second fixing groove, and the first clamping ring is provided with a first through hole for the push rod to pass through.

[0011] By adopting the above technical solution, the first clamping ring is driven to rotate so that the first clamping ring and the bottom wall of the second fixed groove clamp the diaphragm; conversely, the first clamping ring is driven to rotate in the opposite direction, the first clamping ring is removed from the valve body, and the diaphragm is replaced.

[0012] Optionally, a hexagonal groove communicating with the first through hole is formed on the end surface of the first clamping ring away from the fixing cavity.

[0017] By adopting the above technical solution, the diaphragm and the second clamping ring are placed in the second fixing groove. When the mounting column is threadedly connected to the first fixing groove, the mounting column abuts against the second clamping ring, so that the second clamping ring and the bottom wall of the first fixing groove cooperate to clamp the diaphragm, thereby fixing the diaphragm; the top rod of the electric explosion drive structure punctures the diaphragm, and the fire extinguishing agent passes through the diaphragm, the second perforation, the third perforation in sequence, and then is output from the discharge hole.

[0018] Optionally, one end of the mounting column away from the shell is fixedly connected to the second clamping ring.

[0019] By adopting the above technical solution, when the mounting column is threadedly connected to the first fixing groove, the second clamping ring is inserted into the second fixing groove, and the second clamping ring and the bottom wall of the first fixing groove cooperate to clamp the diaphragm; during the process of replacing the diaphragm, the staff is not required to take and place the second clamping piece, thus reducing the disassembly and assembly steps and achieving a labor-saving effect.

[0021] By adopting the above technical solution, the driving member drives the valve core to rotate, so that the through hole is opened, allowing the fire extinguishing agent to enter the valve body through the valve seat.

[0022] Optionally, an operating hole connected to the through hole is opened on the side of the valve body, and the driving member includes an operating rod rotatably connected to the operating hole, one end of the operating rod is connected to the valve core, and an operating handle is provided on the end of the operating rod away from the valve core.

[0025] By adopting the above technical solution, the valve seat can be matched with conversion joints of different sizes to be connected to pipes of different thicknesses, thereby improving the adaptability of the valve seat.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The pressing piece presses the diaphragm tightly so that the diaphragm blocks the opening on one side of the fixed cavity, and prevents the fire extinguishing agent from being discharged from the discharge hole when there is no fire. When a fire occurs, the electric explosion head in the electric explosion drive structure generates explosive energy, which drives the push rod to move, so that the push rod diaphragm is punctured, so that the fire extinguishing agent can pass through the diaphragm and then be discharged from the discharge hole to achieve the fire extinguishing action. The electric explosion drive structure requires fewer internal components, and the overall structure is simple and compact. The electric explosion drive structure can be designed to be smaller in size, so as to adapt to a smaller valve body, so that the container valve can be used in an electrical control cabinet with a smaller internal space.
