Abstract

A plug valve air tightness detection device comprises a box body, at least one tool clamp is arranged on a table top of the box body, a processor and an air supply device are arranged in the box body, the tool clamp comprises a tool bottom plate, a tool seat for placing a plug valve is installed on the front side of the tool bottom plate, an air inlet pipe connected with an air supply device is arranged on the tool seat, and an air inlet of the plug valve is in butt joint with the air inlet pipe. An air cylinder with a guide rail is installed on the rear side of the tool bottom plate, and a pressing hook capable of fixing the plug valve is installed on the front side of the air cylinder. According to the invention, the plug valve only needs to be placed on the tool seat, the pressing hook can fix the plug valve, and the plug on the plugging cylinder can seal the air outlet of the plug valve, so that the air tightness of the plug valve can be automatically detected. The rotary sleeve can be pressed down and rotated, so that whether the valve body leaks air or not under various working conditions can be detected, the detection speed and the detection accuracy of the plug valve are greatly improved, and the plug valve air tightness detection device has a good market prospect.

Description

technical field [0001] The invention relates to a device for detecting the airtightness of a valve, in particular to a device which can automatically detect the airtightness of a gas stove cock valve. Background technique [0002] The plug valve is a closing member or a plunger-shaped rotary valve. By turning the knob rod, the channel port on the valve plug is the same as or separated from the channel port on the valve body to realize opening or closing. The cock valve used for the gas stove mainly has an air inlet, two air outlets and an electromagnetic valve port. The cock valve is also provided with a knob rod, which can be adjusted by pressing down and turning the knob rod to adjust the size of the passage in the valve body. The airtightness test of the valve body should be carried out when leaving the factory. At present, the commonly used detection method is to block the two air outlets and one electromagnetic valve port with three fingers, connect the air inlet with t...
