The invention discloses an intelligent detection device for valve sealing, which relates to the field of valve detection. A detection mechanism is installed, a fixing ring is opened on the outer wall of the protective shell, and one end of the fixing ring is installed with a plurality of groups of cylinders, and the ends of each group of cylinders are connected with a limit ring, and the middle of the limit ring is installed There is a control mechanism, and the inner wall of the protective shell is located on the outer side of the detection mechanism and has an air extraction cavity. In the present invention, after the valve interface is fixed, multiple groups of air cylinders are first activated by the protective shell, the connection mechanism and the detection mechanism provided. When the air is pumped, the negative pressure will pull the air bag to shrink inward, and the connector will be squeezed to move the air bag. The rod slides in the sliding cavity, so that the power-on rod is far away from the power-receiving rod, which effectively solves the problem that the valve cannot be closely fitted with the test device during testing.
Description
technical field [0001] The invention relates to the field of valve detection, in particular to an intelligent detection device for valve sealing. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The control of the valve can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc.; Or under the action of other forms of sensing signals, it acts according to the predetermined requirements, or simply opens or closes without relying on the sensing signals. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift, slide, swing or...
