Embodiment Construction

[0028] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0029] An automatic leak detection device, see figure 1 , figure 2 , image 3 , Including a base 1 and a water tank 2 arranged on the base 1. The water tank 2 is provided with two polished rods 5 of equal height. The two polished rods 5 are arranged vertically and the upper end of the polished rod 5 extends out of the water tank 2. 2 There is a fixing plate 7 connected to the two polished rods 5 at the top. An upper sealing mechanism 4 for sealing the upper end of the valve 11 and a lower sealing mechanism for sealing the lower end of the valve 11 are arranged between the fixing plate 7 and the bottom of the water tank 2 The mechanism 3 and the positioning bracket 10 for positioning the valve 11, the fixed plate 7 is provided with a cylinder 6 for driving the upper sealing mechanism 4, the cylinder body of the cylinder 6 is fixed on the fixed plate 7 inverted,...

Abstract

The invention discloses an automated leakage detection device, which relates to the valve sealing performance testing field. The automated leakage detection device comprises a base and a water tank arranged on the base, wherein two polished rods are arranged in the water tank, the two polished rods are vertically arranged, upper ends of the polished rods extend out of the water tank, a fixed plate connected with the two polished rods is arranged above the water tank, an upper sealing mechanism, a lower sealing mechanism and a positioning bracket are arranged between the fixed plate and the bottom part of the water tank, the upper sealing mechanism is used for sealing an upper end of a valve, the lower sealing mechanism is used for sealing a lower end of the valve, the positioning bracket is used for positioning the valve, and a cylinder used for driving the upper sealing mechanism is arranged on the fixed plate. For solving the problems that an existing valve sealing performance testing method is inconvenient in installation and clamping, low in efficiency, labor-consuming and not high in automation degree, the automated leakage detection device having the advantages of high testing efficiency, convenient installation and clamping as well as high automation degree is disclosed by the invention.

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, tightness testing and torque testing are required before leaving the factory, otherwise there will be greater safety risks. [0003] The prior art does not have a high degree of automation for valve test methods. When testing the sealing performance, sealing gaskets are usually placed outside the two ends of the valve, and a jack or hydraulic cylinder is used to clamp the two ends of the valve to make the sealing gasket Form a seal with the two ends of the valve, and then put the entire sealed valve into the water manually, and then pass compressed gas into the valve to observe whether there...
