An automatic temperature control gas safety valve

Abstract

The invention relates to the related technical field of gas valves, and discloses an automatic temperature-control gas safety valve, which includes a valve body, and an air inlet chamber is provided on one side of the inner wall of the valve body. In the present invention, an electromagnetic block is provided on the inner wall of the movable valve core, and at the same time, movable push blocks are provided at both ends of the electromagnetic block, and the two movable push blocks are respectively in movable contact with the inner wall of the valve, so when the gas volume needs to be adjusted, The movable push block moves to both sides through the energization of the electromagnetic coil, so that the gas flows out from the ventilation groove to realize the on-off control of the gas. At the same time, since the movable valve core is installed on the valve body through the upper cone, when the electromagnetic block When it is magnetic, its movable valve core is pushed by gravity and gas to the movable valve core to make the movable push block close the air groove, thereby increasing the sealing effect, and replacing the spring elastic seal with self-sealing, avoiding the sealing caused by the failure of the spring The phenomenon of failure, and finally achieve the purpose of long-term high-efficiency sealing.

Description

technical field [0001] The invention relates to the related technical field of gas valves, in particular to a gas safety valve with automatic temperature control. Background technique [0002] In order to cut off the gas volume of gas heating equipment such as gas heaters, gas ovens and gas ovens in a timely manner, automatic temperature control gas safety valves are usually used to achieve automatic gas cutoff when the required temperature reaches a certain temperature. Purpose. [0003] The working principle of the existing gas heater is mainly as follows: by installing the valve body in the delivery pipeline, then by fixing the air intake chamber with the gas pipeline inlet, and at the same time, connecting the gas outlet with the gas outlet , at the same time, the gas in the air intake chamber is opened by the electromagnetic safety valve, so that the gas is delivered to the regulating valve core through the gas transmission channel, and the flow rate of the gas from th...
