Abstract

The invention discloses an automatic valve leak-checking device and relates to the field of valve sealing performance test. The device comprises a pedestal and a water tanker which is arranged on the pedestal; the water tank is therein provided with two polished rods; the two polished rods are vertically arranged and the upper ends of the polished rods extend out from the water tank; a fixed plate which is connected with the two polished rods is arranged over the water tank; an upper sealing mechanism which is used for sealing the upper end of the valve, a lower sealing mechanism which is used for sealing the lower end of the valve, and a positioning support which is used for positioning the valve are arranged between the fixed plate and the water tank bottom; the fixed plate is provided with an air cylinder which is used for driving the upper sealing mechanism. The invention is aimed at solving the problems of inconvenient clamping, low efficiency, high labor consumption and low automation degree in present valve sealing performance test methods, and provides a valve leak-checking device which has high test efficiency, convenient clamping, and high automation degree.

Description

technical field [0001] The invention relates to the field of sealing performance testing machines, in particular to an automatic leak detection device for valves. Background technique [0002] Valves are commonly used opening and closing parts for gas or liquid circulation. They are generally used in two important industries: gas pipeline network and water conservancy transportation. Therefore, leak detection and torque testing are required before leaving the factory, otherwise there will be greater safety hazards. [0003] In the existing technology, the automation degree of the valve test method is not high. When testing the sealing performance, the gasket is usually placed outside the two ends of the valve, and the two ends of the valve are clamped by a force-applying device such as a jack or a hydraulic cylinder, so that the gasket Form a seal with the two ends of the valve, then put the whole sealed valve into the water manually, and then pass compressed gas into the va...
