Description

Technical Field

[0001] This utility model relates to the field of gas emergency shut-off valve technology, and in particular to an electromagnetic gas emergency shut-off valve structure. Background Technology

[0002] The electromagnetic gas emergency shut-off valve is a device that plays a key safety protection role in the gas system. The electromagnetic gas emergency shut-off valve works based on the principle of electromagnetic force drive.

[0003] In existing technology, when the electromagnetic coil receives an external electrical signal, an electromagnetic force is generated in the coil, which attracts the valve core to overcome the spring force or other resistance, causing the valve to close quickly and cutting off the gas supply channel. When the fault is cleared or the gas supply needs to be restored, the valve can be reopened by manual operation.

[0004] However, in the aforementioned prior art, the common structure is that the valve disc of the shut-off valve is surrounded by a sealing gasket, which leads to low efficiency during assembly. Utility Model Content

[0005] The purpose of this invention is to provide an electromagnetic gas emergency shut-off valve structure that solves the problem of low assembly efficiency caused by the common structure in the prior art, which is a valve disc surrounded by a sealing gasket.

[0006] To achieve the above objectives, this utility model provides an electromagnetic gas emergency shut-off valve structure, including a valve body, a valve cover, a moving iron core, a valve disc, and a sealing gasket. The upper end of the valve body has an installation port, the valve cover is disposed at the installation port, the sealing gasket is disposed inside the valve body, the valve disc is disposed on the sealing gasket, and one end of the moving iron core passes through the valve cover and is adapted to the sealing gasket.

[0007] The moving iron core includes a first main rod, a second main rod, and a third main rod. The second main rod is fixedly connected to the first main rod and is located at the lower end of the first main rod. The third main rod is fixedly connected to the second main rod and is located at the lower end of the second main rod. The second main rod is located inside the valve cover, and the third main rod is adapted to the sealing gasket.

[0008] The electromagnetic gas emergency shut-off valve structure further includes a first baffle and a second baffle. The first baffle is fixedly connected to the inner bottom wall of the valve body, and the second baffle is fixedly connected to the inner side wall of the valve body. The sealing gasket is disposed on the first baffle and the second baffle.

[0009] The valve body has two symmetrical gas ports.

[0010] The diameter of the second main rod is 6 cm, and the diameter of the third main rod is 4 cm.

[0011] This utility model discloses an electromagnetic gas emergency shut-off valve structure. The upper end of the valve body is sealed and fixed by the valve cover, and the moving iron core is embedded and adapted to the sealing gasket. Compared with the existing wrap-around installation method, the embedded method can greatly improve the assembly efficiency and the structure is more reliable. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] Please see Figure 1 , Figure 1 This is a cross-sectional view of the entire utility model.

[0017] This utility model provides an electromagnetic gas emergency shut-off valve structure, including a valve body 1, a valve cover 2, a moving iron core 3, a valve disc 4, and a sealing gasket 5. The upper end of the valve body 1 has an installation port 11, the valve cover 2 is disposed at the installation port 11, the sealing gasket 5 is disposed inside the valve body 1, the valve disc 4 is disposed on the sealing gasket 5, and one end of the moving iron core 3 passes through the valve cover 2 and is adapted to the sealing gasket 5.

[0018] In this embodiment, the upper end of the valve body 1 is sealed and fixed by the valve cover 2, and the moving iron core 3 is fitted with the sealing gasket 5. Compared with the existing wrap-around installation method, the embedded method can greatly improve the assembly efficiency and the structure is more reliable.
