Easy-to-rotate plug valve

Abstract

The invention relates to an easy-to-rotate plug valve. The easy-to-rotate plug valve comprises a valve body and a valve element, wherein a rotating cavity for the valve element to rotate is formed in the valve body; the valve body is provided with rolling assemblies and fixing holes capable of allowing the rolling assemblies to be fixed; and the rolling assemblies are abutted to the valve element. The easy-to-rotate plug valve is provided with the rolling assemblies, the rolling assemblies are arranged symmetrically, pressure of elastic pieces on balls uniformly acts on ball grooves, thus, the balls are in point contact with the ball grooves, original surface contact between the valve element and the valve body is changed into point contact between the balls and the ball grooves, meanwhile, sliding friction becomes rolling friction, frictional resistance is greatly reduced, and by the structure, a purpose of facilitating rotation is achieved.

Description

technical field [0001] The invention relates to the technical field of gas control for household gas stoves, in particular to an easy-to-rotate cock valve. Background technique [0002] Gas stoves are common household appliances used in every household. Traditional gas stoves generally use plug valves to control the opening and closing of the stove and to adjust the firepower of the stove head. The plug valve generally includes a valve body, a valve core and a valve connected to the valve core. Connecting rod, by pressing and rotating the knob to drive the connecting rod, the connecting rod synchronously drives the valve core to rotate to connect the gas channel in the valve body and adjust the gas volume in the gas channel. Rotate the spool frequently to adjust the firepower, especially in the harsh environment of the cooker, which needs to be in a high temperature state frequently, causing the grease on the surface of the spool to dry up, and the processing of the spool an...

[0002] Gas stoves are common household appliances used in every household. Traditional gas stoves generally use plug valves to control the opening and closing of the stove and to adjust the firepower of the stove head. The plug valve generally includes a valve body, a valve core and a valve connected to the valve core. Connecting rod, by pressing and rotating the knob to drive the connecting rod, the connecting rod synchronously drives the valve core to rotate to connect the gas channel in the valve body and adjust the gas volume in the gas channel. Rotate the spool frequently to adjust the firepower, especially in the harsh environment of the cooker, which needs to be in a high temperature state frequently, causing the grease on the surface of the spool to dry up, and the processing of the spool and the concentricity of the valve body are not enough, it is easy to cause the spool to be stuck Phenomenon, the valve core cannot be rotated, and the valve body rotation adjustment fails and the cooker is scrapped.
