Large-aperture gas medium electric valve

Abstract

The invention discloses a large-aperture gas medium electric valve. A base plate and an auxiliary substrate are respectively mounted on a housing body, wherein the base plate is arranged above the auxiliary base plate; an air vent is formed in the base plate; a plurality of guide posts are arranged between the base plate and the auxiliary substrate; pressing plates and gate plates used for controlling the opening and closing of the air vent are mounted on the guide posts in a sliding manner; elastic components are arranged between the pressing plates and the gate plates; the pressing plates are connected to a linear driving device which is used for driving the pressing plates to move up and down in a reciprocating manner; upper limit position sensors are arranged on the pressing plates; lower limit position sensors are arranged on the auxiliary base plate. The large-aperture gas medium electric valve is used for sealing air channels. Compared with ball valves, butterfly valves and gate valves, the large-aperture gas medium electric valve is more portable; the sealing performance of the valve is greatly improved; various large-pipe-diameter valves can be manufactured; the large-aperture gas medium electric valve is applicable to various air vent pipelines; the technical problem that the sealing cannot be implemented when the gate valves, particularly large-calibre valves, are applied to airflow can be thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a gas medium electric valve with a large aperture. Background technique [0002] There are many kinds of valves in the prior art, such as ball valves, butterfly valves, gate valves, etc. These valves, such as ball valves and butterfly valves, are mainly used for liquid gate control. They are very bulky, expensive, and not tight enough for gas gate control. . When the gate valve is used for the opening and closing of the gas fluid, due to structural reasons, it cannot realize the sealing function at all, and there are few large-diameter valves, and the cost is expensive. Contents of the invention [0003] The invention proposes a large-diameter gas medium electric valve, which is applied to the sealing of gas passages. Compared with ball valves, butterfly valves and gate valves, it is not only lighter, but also greatly improves the sealing performance of the valves. It can produ...

[0003] The invention proposes a large-diameter gas medium electric valve, which is applied to the sealing of gas passages. Compared with ball valves, butterfly valves and gate valves, it is not only lighter, but also greatly improves the sealing performance of the valves. It can produce various large-diameter valves, suitable for Various ventilation pipelines have completely solved the technical problem that gate valves cannot be sealed when applied to gas fluids, especially when large-diameter valves are applied to gas fluids
