Embodiment Construction

[0020] Such as figure 1 , figure 2 As shown, a gas cock valve assembly includes a cock valve and a solenoid valve 7; The solenoid valve 7 includes: a cavity 8 and a thimble 3 . The thimble 3 is equipped with a first spring 6, and the first spring 6 pushes away the electromagnetic valve 7.

[0021] The thimble 3 is equipped with a second spring 5 .

[0022] The brake wheel 2 is a cam.

[0023] The first spring 6 is a buffer spring; the second spring 5 is a return spring.

[0024] Implementation steps:

[0025] figure 1 is a 0° cross-sectional view of the plug valve assembly, figure 2 It is a cross-sectional view of the 90° safe opening of the solenoid valve 7 of the cock valve assembly, and the cock valve assembly is rotated from 0° to 90° to realize the safe opening of the solenoid valve 7 .

[0026] The switch shaft 1 is pressed down at 0° for about 3mm and rotated counterclockwise to 90°. During this process, the switch shaft 1 is pressed down to release the 0° sel...

Abstract

The invention provides a gas plug valve assembly. The gas plug valve assembly comprises a plug valve and a magnetic valve. The plug valve comprises a valve body, a valve seat, a valve core, a switch shaft, a braking wheel and a valve needle. The magnetic valve comprises a type cavity and a thimble. A first spring is installed on the thimble. The magnetic valve is pushed by the first spring in an opening mode. A second spring is installed on the thimble. The braking wheel is a camshaft. A buffering spring is added in pushing the magnetic valve, thus the safe opening of the magnetic valve is achieved. Service life of the magnetic valve can be prolonged at the same time when the damage rate of the magnetic valve is reduced. Function reliability of the gas plug valve assembly is improved.

Description

technical field [0001] The invention relates to a gas cock valve assembly, which is used for the safety protection of gas appliances. Background technique [0002] As the National Gas Appliances Association pays more and more attention to the safety of gas appliances in recent years, all household stoves produced by domestic stove manufacturers are required to be equipped with flameout protection devices, so that all plug valve assemblies must be equipped with solenoid valves to achieve This function means that the demand for safety plug valve assembly will greatly increase. At present, most of the safety plug valve assemblies on the market open the solenoid valve structure with a hard top to open. Since the solenoid valve is a precision electronic product, the solenoid valve manufacturer stipulates that the force to open the solenoid valve should be ≤ 3Kgf. And in the process of production and transportation, it is very easy to exceed this pressure and damage the electroma...
