Quick change connector device for hose assembly pressure test and hose assembly pressure test system

Abstract

The invention discloses a quick change connector device for a hose assembly pressure test and a hose assembly pressure test system. The quick change connector device for the hose assembly pressure test comprises a transitional connector, a piston cylinder and a transitional core which are sequentially connected with one another, wherein a piston-free cavity in the cylinder body of the piston cylinder is communicated with the transitional connector; one end of the transitional core is sleeved with a piston of the piston cylinder; the other end of the transitional core is provided with a structure connected with a hose assembly connector; a communicating pipeline is formed on the piston; a liquid guiding hole is formed in the transitional core; and a pressure control valve for communicatingthe liquid guiding hole and the communicating pipeline when pressure is higher than a set value is arranged between the liquid guiding hole and the communicating pipeline. The hose assembly pressure test system comprises a pressure test loop, and a boosting pump and two connector devices which are arranged on the pressure test loop; a hose assembly to be tested is connected between the two connector devices; and the connector devices are the quick change connector devices. The quick change connector device for the hose assembly pressure test and the hose assembly pressure test system have theadvantages of improving installing speed, improving test efficiency, reducing labor intensity and the like.

Description

technical field [0001] The invention mainly relates to the field of hose pressure detection equipment, in particular to a pressure test joint device and a pressure test system. Background technique [0002] The hose assembly refers to a hose with pipe joints installed at both ends. The joint nut of the hose assembly joint can slide within a certain range along the joint mandrel. The head of the joint mandrel has a protruding conical surface that can be matched with the bottom joint with a concave conical surface that needs to be connected. Fasten with union nuts. [0003] The pressure test of the hose assembly is an important source of technical parameters of the hose assembly, and it is also the reliance of the quality assurance of the hose assembly. The traditional hose assembly is clamped and disassembled in the following steps before and after the pressure test: [0004] 1. Select a transition joint that can match the upper joint of the hose assembly to be tested, and...

AI Technical Summary

Problems solved by technology

[0010] The disadvantage of the above-mentioned pressure test clamping (disassembly) method is that each time a hose assembly is tested, the same action needs to be repeated, the steps are cumbersome, time-consuming and labor-intensive, and the efficiency is extremely low

[0015] The disadvantage of this method is that the operation is troublesome and the work efficiency is low.
