Description

Electromagnetic type gas emergency cut-off valve structure Technical Field The utility model relates to the technical field of gas emergency shut-off valves, in particular to an electromagnetic gas emergency shut-off valve structure. Background The electromagnetic gas emergency cut-off valve is a device which plays a key safety protection role in a gas system and works based on an electromagnetic force driving principle. In the prior art, when an electromagnetic coil receives an external electric signal, electromagnetic force is generated in the coil, and the valve core is attracted to overcome spring force or other resistance, so that the valve is quickly closed, a gas supply channel is cut off, and when the fault is eliminated or gas supply needs to be recovered, the valve can be opened again through manual operation. However, in the prior art described above, it is a common practice to have a gasket around the flap of the shut-off valve, resulting in low efficiency in assembly. Disclosure of utility model The utility model aims to provide an electromagnetic gas emergency cut-off valve structure, which solves the problem that the efficiency of assembly is low because a sealing gasket is used for wrapping a valve clack of the cut-off valve in a surrounding manner in the prior art. In order to achieve the above purpose, the utility model provides an electromagnetic gas emergency cut-off valve structure, which comprises a valve body, a valve cover, a movable iron core, a valve clack and a sealing gasket, wherein the upper end of the valve body is provided with a mounting opening, the valve cover is arranged at the mounting opening, the sealing gasket is arranged in the valve body, the valve clack is arranged on the sealing gasket, and one end of the movable iron core penetrates through the valve cover and is matched with the sealing gasket. The movable iron core comprises a first main rod, a second main rod and a third main rod, wherein the second main rod is fixedly connected with the first main rod and is positioned at the lower end of the first main rod, the third main rod is fixedly connected with the second main rod and is positioned at the lower end of the second main rod, the second main rod is positioned in the valve cover, and the third main rod is matched with the sealing gasket. The electromagnetic gas emergency cut-off valve structure further comprises a first baffle and a second baffle, the first baffle is fixedly connected with the inner bottom wall of the valve body, the second baffle is fixedly connected with the inner side wall of the valve body, and the sealing gasket is arranged on the first baffle and the second baffle. Wherein, two symmetrical gas interfaces are arranged on the valve body. The diameter of the second main rod is 6cm, and the diameter of the third main rod is 4cm. According to the electromagnetic gas emergency cut-off valve structure, the upper end of the valve body is fixed in a sealing mode through the valve cover, the movable iron core is matched with the sealing gasket in an embedded mode, and compared with a wrapped type installation mode in the prior art, the embedded type gas emergency cut-off valve structure can greatly improve the assembly efficiency and is more reliable in structure.
