Technical Field

The invention relates to the field of mechanical equipment, in particular to a leakage detection jig for a national five-water pipe.

Background

Urea sensor installs in the urea case, be the key instrument for detecting urea liquid level height, urea sensor's structure generally all comprises urea pipe, heating pipe and electron tube, wherein the heating pipe is the water pipe that metal material made in fact, the inside circulation is hot water, in order to increase the heat radiating area of water pipe, general condition all can design the water pipe into the heliciform, now be the water pipe, just need test its gas tightness, prior art's test mode is all that the manual work is aerifyd the back to the water pipe through aerating device and is immersed the aquatic and detect, the test efficiency ratio is lower.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a safe and reliable national five-water-pipe leakage detection jig with high detection efficiency.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

the utility model provides a five state water pipes tool that leaks hunting, includes the frame and establishes the basin on frame upper portion be equipped with first cylinder and second cylinder respectively in frame both sides, with the support that links to each other of first cylinder and second cylinder, establish the bottom plate on the support, install be the third cylinder on the bottom plate, with the inflation piece that links to each other of third cylinder, establish be inflation nozzle and rubber end cap on the inflation piece, arrange in the inflation nozzle front end be clamping mechanism, clamping mechanism is including establishing the fourth cylinder in the bottom plate side, with what the fourth cylinder linked to each other is first taking the tooth rectangular, be equipped with first stopper on first taking tooth rectangular, be equipped with first spacing groove on the first stopper first taking tooth rectangular both sides be equipped with the second simultaneously and take the tooth rectangular, be equipped with the second stopper on the second takes the tooth rectangular, and a second limiting groove is formed in the second limiting block, and the direction of the first limiting groove is opposite to that of the second limiting groove.

Compared with the prior art, the invention has the beneficial effects that:

the leakage detection jig for the national-fifth water pipe is novel in design, compact and reasonable in structure, high in automation degree, high in testing efficiency, safe and reliable.
