Description

Technical Field

[0001] The utility model relates to the technical field of warehouse fire protection, in particular to a gas-electric controlled fire protection valve. Background Art

[0002] Fire protection systems are crucial safety features in the petrochemical and warehousing sectors, and fire valves are a key component of these systems. Once a fire breaks out, the duration the valves remain open becomes crucial to the success of firefighting operations.

[0003] The existing fire valve is generally a pneumatic valve 200, such as Figure 1 As shown, the pneumatic valve 200 uses a cylinder to drive the valve core 204 up and down to open and close the fire valve. The cylinder includes a housing 201, a piston 202, and a connecting rod 203. The piston 202 divides the internal space of the housing 201 into an upper air chamber 205 and a lower air chamber 206. The housing 201 is provided with an upper air hole 207 and a lower air hole 208. The upper air hole 207 is connected to the upper air chamber 205, and the lower air hole 208 is connected to the lower air chamber 206. The valve core 204 is fixedly connected to the piston 202 via the connecting rod 203. The upper air hole 207 and the lower air hole 208 are both connected to an external air pump. This structural arrangement means that when opening the fire valve, it is necessary to wait until the air pressure in the lower air chamber 206 exceeds the air pressure in the upper air chamber 205. This process takes a long time, resulting in a long opening time of the fire valve. In addition, if gas leaks in the lower air chamber, the fire valve cannot be opened.

[0004] Therefore, it is necessary to develop a fire valve that can be opened quickly when the fire valve needs to be opened. Utility Model Content

[0005] Based on this, it is necessary to provide a gas-electrically controlled fire valve to address the problem that the existing fire valve is a pneumatic valve and takes a long time to open.

[0006] and a valve core and a driving mechanism. The lower end of the valve body is connected to a water inlet pipe, and the connection between the valve body and the water inlet pipe is provided with a valve slot adapted to the valve core. One side of the valve body is connected to a water outlet pipe. The driving mechanism is fixedly arranged on the valve body. The driving mechanism includes a shell, a piston, a connecting rod, an electromagnet and a permanent magnet. The piston is movably arranged in the shell to divide the internal space of the shell into an upper chamber and a lower chamber.

The electromagnet is fixed to the top of the shell, and the permanent magnet is fixedly connected to the piston.

[0007] The above-mentioned pneumatic and electric control fire valve can quickly drive the valve core to move upward and open the fire valve through the cooperation of the valve body, the valve core and the driving mechanism. This is because the electromagnet is powered by an external power source and can generate magnetism to attract the magnetism of the permanent magnet in a very short time. Compared with the pneumatic control mode, this can make the piston move upward faster, thereby opening the fire valve faster and improving the success rate of firefighting operations in the event of a fire.

[0010] In one of the embodiments, the limiting block is a rubber block or a silica gel block.

[0011] In one of the embodiments, the pneumatic and electric control fire valve further comprises a waterproof assembly, which comprises a waterproof ring and a fixing ring. The top of the valve body is provided with a waterproof groove, and the waterproof ring is embedded in the waterproof groove. The waterproof ring is sleeved outside the connecting rod, and the fixing ring is sleeved outside the connecting rod. The fixing ring is screwed with the valve body to fix the waterproof ring in the waterproof groove.
