A leak detection device for valve production

Abstract

The present invention is applicable to the detection field of valve bodies, and provides a leak detection device for valve production, which includes a hot-melt glue extruding mechanism for containing pressure oil. The hot-melt glue extruding mechanism includes a containing casing, a support Plate, clamping clip and hot melt glue output ring sleeve, a pressurizing element is arranged in the containing shell, and one end of the containing shell is also fixedly connected to the mounting plate through a connecting plate, and a support is fixedly connected to the outer wall of the containing shell The support plate is rotatably connected with a plurality of clamping clips, and the piston plate in the pressurizing element performs piston movement in the containing housing, so that under one push, the pressure oil is introduced at the other end of the pipe joint. Put oil-absorbing paper on it, and when there are oil stains on the oil-absorbing paper, judge whether there is oil leakage in the ball valve, which proves that the sealing performance of the valve body is reliable, which makes this design have higher detection reliability and avoids leakage caused by gaps. The act of repeatedly checking the sealing performance of the valve core in the valve body caused by oil.

Description

technical field [0001] The invention belongs to the detection field of valve bodies, and in particular relates to a sealing performance detection device used in valve production. Background technique [0002] The definition of a valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. The valve is a device that makes the medium in the piping and equipment, such as liquid, gas, powder, etc. flow or stop, and can control its flow. The material of the valve body is different according to different process media. Commonly used materials are: cast iron, cast steel, stainless steel, carbon steel, plastic, copper, etc. [0003] The traditional airtightness test method is soaking water method, for example, direct soaking in water, the specific steps are water depth and soaking time to correspond to IP waterproof level tests at all levels. Observe whether there is water in the product as its judgment standard. Or the indirect water soaking ...

Problems solved by technology

[0005] The purpose of the embodiment of the present invention is to provide a leak detection device for valve production, which aims to solve the problem that electronic valve products may cause irreparable damage to electronic components once water enters them. The electronic components installed on the valve body are actuators, which can accurately monitor the torque and measure the valve position of the valve body. Once damaged, it is particularly troublesome to repair.

There is a problem of leaking but not necessarily producing bubbles when there is a micro leak
