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. The automatic temperature control gas safety valve comprises a valve body, and a gas inlet chamber is formed in one side of the inner wall of the valve body. According to the automatic temperature control gas safety valve, an electromagnetic block is arranged on theinner wall of a movable valve element, meanwhile, movable pushing blocks are arranged at the two ends of the electromagnetic block, the two movable pushing blocks make movable contact with the inner wall of the valve body, therefore, when the gas amount needs to be adjusted, the movable pushing blocks are driven to move towards the two sides through electrification of an electromagnetic coil, thengas flows out from ventilation grooves, and control over flowing and closing of gas is achieved; meanwhile, due to the fact that the movable valve element is installed on the valve body through an upper cone, when the electromagnetic block is non-magnetic, the movable valve element is stressed by gravity and thrust of the gas to the movable valve element to enable the movable pushing blocks to seal the ventilation grooves, and the sealing effect is improved; and spring elastic sealing is replaced with self-sealing, the phenomenon of sealing failure caused by spring failure is avoided, and finally the purpose of long-term efficient sealing is achieved.

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...
