Problems solved by technology

[0002] Copper or cast iron gate valves or cock valves are used on city gas branch pipes. The sealing packing oil used is easy to age, and the sealing area between the gate or cock core and the valve body is large and easy to wear, resulting in gas leakage or internal leakage. Maintenance Grinding is difficult, resulting in waste of gas, and copper and cast iron materials are not economical

Abstract

A low-pressure fuel gas valve is used at the front of a fuel gas branch and a fuel gas appliance. A valve body is provided with a main chamber and an auxiliary chamber under the main chamber. A pair of permanent magnets, which is assembled at the internal side and the external side of a valve shell, is arranged inside the valve body. The permanent magnet is equipped with a nylon switch connecting part, a switch and a handle. Steel hoops are embedded at two ends of the valve body. The switch and the connecting part are embedded on the permanent magnet in a fixing way. The nylon switch is embedded on the permanent magnet outside the valve in a fixing way. A seal cover adheres to the valve body. The invention is provided with the advantage that no cooper material is used, no leakage will happen, the resistance is small, the fuel gas pressure loss is reduced, the stove thermal efficiency is promoted, and time and gas are saved.

Description

technical field [0001] The invention relates to a gas branch pipe and a low-pressure gas valve used in front of a gas appliance. Background technique [0002] Copper or cast iron gate valves or cock valves are used on city gas branch pipes. The sealing packing oil used is easy to age, and the sealing area between the gate or cock core and the valve body is large and easy to wear, resulting in gas leakage or internal leakage. Maintenance Grinding is difficult, resulting in waste of gas, and copper and cast iron materials are not economical. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a gas branch pipe and a low-pressure gas valve for gas appliances. [0004] The technical solution of the present invention is: a low-pressure gas valve for gas branch pipes and gas appliances, which is characterized in that it is composed of a polyester plastic valve body and a permanent magnet valve core. The ...
