Abstract

A static hydraulic equipment connector belongs to the technical field of plastic pipe production, and particularly relates to a connector for static hydraulic strength tests of straight wall pipes (polyethylene (PE) pipes, pentatricopeptide repeats (PPR) pipes, polyvinyl chloride (PVC) pipes and the like). The static hydraulic equipment connector comprises two groups which are respectively installed at both ends of a test pipe, wherein one group is composed of an end cap 6, clamping plates 2, an O-shaped ring 4 and a screw thread 3. The screw thread is an external thread. The screw thread and the O-shaped ring are sequentially sleeved into one end of the test pipe 1. The end cap is screwed tight with the screw thread. The two semicircular clamping plates are installed on the inner side face of the end cap through bolts. The two clamping plates oppositely fasten the turnover edge of the pipe to be integrated through bolts. The test pipe is assembled and placed in a test bin and filled with water through a water inlet hole for a bulge test. When the test pipe is full of water, an air valve of a vent hole is closed. When authorized pressure is achieved, the pressure is maintained in a specific time, products approved by the test are up to standard and otherwise the products are not up to standard, thereby ensuring qualified products are delivered.

Description

Hydrostatic device junction

Technical field

The utility model belongs to the technical field that plastic pipe is produced, and specifically is whether detection plastic tube internal pressure strength is up to standard, is used for the joint that straight wall tube material class (polythene PE pipe, PPR pipe, pvc pipe etc.) is carried out hydrostatic strength test.

Background technology

About the existing many patterns of hydrostatic device junction, with reference to plastic pipe GB/T6111-2003 FLUID TRANSPORTATION with thermoplastic plastic pipe internal pressure-resistant test method.Be divided into the A type according to the mode of being installed and be not with two types on pull bar and Type B band pull bar.A type anchor clamps are applicable to various plastic pipes, and the Type B anchor clamps generally are applicable to PVC.

Summary of the invention

The purpose of the utility model is the requirement of tubing being carried out hydrostatic strength test in order to satisfy among the GB GB/T13663-2000, solves existing tubing simultaneously and carries out the bad problem of hydrostatic strength test sealing property.

Hydrostatic device junction comprises two groups, is installed in the two ends of test tubing respectively; Wherein is made up of plug, clamping plate, O shape circle and screw thread for one group, screw thread is an external thread, and screw thread and O shape circle are inserted in proper order tests tubing one end; Plug and screw thread are screwed; The clamping plate semicircular in shape, two clamping plate are installed on the plug medial surface by bolt, and two clamping plate fasten tubing relatively, and to turn edge by bolt be one.

The plug series connection that to be tested the tubing two ends by reinforcing bar is fixing, the reinforcing bar symmetric arrangement.

Installation method: earlier screw thread, O shape circle are inserted in tubing one end in order, insert tubing in the plug again, then screw thread is screwed in the plug, overlap train wheel bridge then, fix clamping plate and plug with bolt hole, and locking.At last with two semicircle clamping plate respectively with on the bolted, form positive circular.Promptly accomplished the plug assembling of tubing one end, taked same procedure to install equally the tubing other end is assembled, at last vent port setting pressure table and air valve have been arranged, the inlet opening connects water pipe, promptly accomplishes assembly work.

Assemble test tubing, be placed in the test cabin,, in test tubing, during fills with water, close the air valve of vent port through inlet opening water filling bulge test.When reaching authorised pressure, keep-up pressure at official hour, be specification product through what test, otherwise be substandard product, guarantee product export up to standard.

The invention effect:

1, this connected mode, with other joints, key is to have in the plug a circular-arc sealing surface, more closely contacts with the O shape circle that adopts, and sealing is more superior;

2, the increase of clamping plate can prevent the stripped thread because of silk, and the connection reliability of further fixture splice and tubing, avoids tubing in height, to depress with joint and comes off.
