Pipe fitting leakage sealing and detecting device

Abstract

The invention provides a pipe fitting leakage sealing and detecting device which is applied to the field of pipeline sealing and detecting of automotive pipe fittings. A fixed seat (5) and a base (6) of the pipe fitting leakage sealing and detecting device are connected. A gap is reserved between the fixed seat (5) and the base (6), a piston (7) and a pipeline (8) are arranged in the fixed seat (5), one end of the pipeline (8) is connected with leakage detecting equipment (9) providing leakage detecting liquid with pressure into the pipeline (8), the other end of the pipeline (8) extends to form a piston body portion (10) penetrating through the piston (7), and the piston (7) is set to extend to one side close to the base (6) when the leakage detecting equipment (9) provides the leakage detecting liquid with pressure. By pushing the piston with elasticity of a spring and pressure of the leakage detecting liquid, clamping force is increased, sealing at the left end face and the right end face of a ball head is improved, and pipeline leakage sealing and detecting of pipe fittings can be conveniently quickly completed.

Description

technical field [0001] The invention belongs to the technical field of pipeline sealing detection of automobile pipe fittings, and more specifically relates to a pipe fitting sealing leak detection device for detecting the pipeline of pipe fittings. Background technique [0002] With the continuous innovation of the pipeline structure of automobile power steering pipe fittings and the continuous increase of product types, users have higher requirements for pipeline performance. Therefore, the sealing effect that directly affects the pipeline performance has attracted much attention. In the prior art, a leak detection device is generally used to solve the problem of inability to accurately detect leaks due to insufficient pressure in the pipeline due to partial air leakage of the ball head. But the existing leak detection device can no longer satisfy the test of its tightness. Because the device with this structure cannot well seal the end face with the ball head in the pip...

Problems solved by technology

In the prior art, a leak detection device is generally used to solve the problem of insufficient pressure in the pipeline due to the leakage of the ball head part and the problem of inability to accurately detect leaks

However, the existing leak detection device can no longer meet the test of its tightness.

Because the device with this structure cannot seal the end face with the ball head in the pipeline well, and the equipment cannot perform accurate leak detection on the pipeline
