Abstract

The invention discloses a gas magnetic control valve which belongs to the control valve technical field of a gas pipeline; the problem to be solved is as follows: providing a gas magnetic control valve, specifically a magnetic control valve with small seal contact area and ring-shaped line contact; controlling the opening or closing manually; providing simple valve manufacturing process with highprecision, good sealing performance and low cost. The proposal adopted is as follows: a valve plate is fixed at the left end of a valve stem in a side channel B; the right end of the valve stem is sheathed inside the valve stem sleeve of a T-typed cover; the left end of a spring is sheathed at one side of the valve stem and leans against the valve plate which leans against the edge of a valve holein the left so as to block the valve hole; the right end of the spring is sheathed outside the valve stem sleeve of the T-typed cover and leans against the left wall of the T-typed cover which is fixed on the channel opening of the side channel B by sealing thread; the outer wall of the top part of the side channel B of the valve body is provided with a rotating plate by a pin; the end of the rotating plate is fixed with an external magnet; the gas magnetic control valve of the invention is suitable to be used indoors and outdoors.

Description

technical field [0001] The gas magnetic control valve of the invention belongs to the technical field of gas pipeline control valves. Background technique [0002] In the field of gas pipeline technology at home and abroad, solenoid valves are often used to control the on-off of gas. In particular, it is very common for gas cookers to use solenoid valves to control gas on-off, and its technology is very mature. For example, some large-scale advanced gas water heater industries in China, All the gas supply systems of gas water heaters use solenoid valves to control the on-off of gas, and the solenoid valves work by generating magnetic fields through energized coils. [0003] For a long time, the indoor valves used in the field of gas technology mainly include plug valves, ball valves, and butterfly valves. The greater the closing resistance. Especially the valve used between the gas pipeline and the gas cooker, due to frequent opening and closing for a period of time, inter...
