Hydraulic pressure test device for plastic water supply pipe fitting

Abstract

The invention relates to a hydraulic pressure test device for a plastic water supply pipe fitting. The hydraulic pressure test device for the plastic water supply pipe fitting is composed of a choke plug, a clamp and a blocked core, wherein the choke plug is of a hollow ring structure, multiple bolt through holes are formed in the upper surface of the choke plug, the blocked core is assembled in the choke plug, multiple bolt holes are formed in the upper surface of the blocked core, ring sides for extending outwards is arranged below the blocked core, multiple rubber sealing rings are formed between the ring side and the choke plug, pressure rings for mutual insulation are arranged among the rubber sealing rings, an adapter is arranged at the center of the blocked core, a water path is at the center of the adapter, the upper part of the adapter is connected to a hydraulic pressure water pipe, air vents matching with a sealing bolt are formed in the blocked core, the choke plug and the blocked core are matched through a bolt, the clamp is of two hollow semicircular structures, multiple pawls are formed in the inner wall of the clamp, side wings for extending outwards are arranged at the two sides of the clamp, and multiple bolt holes are formed on the side wings. The hydraulic pressure test device for the plastic water supply pipe fitting has the beneficial effects of being simple in mounting procedures, convenient and fast in operation, saving cost as well as curing time as usage of tubular products and glue or other adhering materials is unnecessary and improving detection efficiency.

Description

technical field [0001] The invention relates to a test device, in particular to a new test device for hydraulic test of plastic water supply pipe fittings. Background technique [0002] The national standards for plastic water supply pipe fittings have been implemented for many years, but there is no special hydraulic test device for the hydraulic test of plastic water supply pipe fittings. Most of them use plastic pipes and pipe fittings for glue bonding and curing tests, and use special hydraulic plugs for pipes. , this method is time-consuming and laborious, and increases the cost of the test. Because the test process is too long and the production line does not stop, when the test result is unqualified, a large number of unqualified products will be produced; and when the bonding between the pipe and the pipe fitting is not solidified enough, water leakage will occur, resulting in the failure of the test, and it needs to be re-prepared Test; sometimes the pipe fittings ...

[0002] The national standards for plastic water supply pipe fittings have been implemented for many years, but there is no special hydraulic test device for the hydraulic test of plastic water supply pipe fittings. Most of them use plastic pipes and pipe fittings for glue bonding and curing tests, and use special hydraulic plugs for pipes. , this method is time-consuming and laborious, and increases the test cost

Because the test process is too long and the production line is non-stop, when the test result is unqualified, a large number of unqualified products will be produced; and when the bonding between the pipe and the pipe fitting is not solidified enough, water leakage will occur, resulting in the failure of the test, and it needs to be re-prepared Test; sometimes the pipe fittings are broken due to the pipe rupture, which makes it difficult to judge the test results

For production enterprises, this undoubtedly greatly increases the production cost, and the product quality cannot be effectively controlled
