A gas valve that is easy to disassemble and assemble

Abstract

This utility model relates to the field of gas valve technology and discloses a gas valve that is easy to disassemble and assemble. The gas valve body includes two first connecting flanges, each with a second connecting flange connected to one side. A pipeline is fixedly connected to one side of each second connecting flange. Two sliding plates are slidably disposed on the outer side of the gas valve body, with the sliding plates positioned on one side of the first connecting flanges. Multiple pins are fixedly disposed on one side of each sliding plate, with the pins penetrating the first and second connecting flanges. When the gas valve body is connected to the pipeline, the second connecting flange is connected to the first connecting flange. The sliding plates are slid, allowing the pins to penetrate the first and second connecting flanges. Then, a push plate is rotated, causing one end of the push plate to tightly abut against the first connecting flange. This causes a limiting plate to push the second connecting flange into tight contact with the first connecting flange, facilitating subsequent disassembly and assembly of the first and second connecting flanges.

Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, specifically a gas valve that is easy to disassemble and assemble. Background Technology

[0002] Gas valves are key components used to control gas flow and are widely used in various industrial and civil fields. Their main function is to cut off, connect, or regulate the gas flow in pipelines to ensure the normal operation and safety of the system. The working principle of a gas valve is based on its structural design, which typically includes a high-pressure chamber and a low-pressure chamber. The high-pressure chamber is connected to the gas cylinder, and the low-pressure chamber is the gas outlet leading to the system in use. The pressure in the low-pressure chamber is controlled by adjusting the screw to achieve the required pressure value. The safety valve is used to protect the pressure reducing valve and automatically release gas when the outlet pressure exceeds the permissible value, ensuring safe use. However, when connecting gas valves to pipelines, they are usually fixed with multiple bolts, which makes disassembly and assembly inconvenient and reduces efficiency. Therefore, a gas valve that is easy to disassemble and assemble is proposed. Utility Model Content
