Embodiment Construction

[0010] Referring to the accompanying drawings, a pipe joint for pipe wall instruments of the present invention is equipped with a joint body 1 , and the joint body 1 is provided with a central through hole 11 . The joint main body 1 is arranged in the pipe wall hole of the plastic pipe or the steel skeleton plastic composite pipe 2 .

[0011] The parts of the main body 1 of the joint protruding respectively from the inner surface of the pipe wall and the outer surface of the pipe wall are provided with external threads. The joint main body 1 located on the inner surface of the pipe wall is equipped with a sealing washer 3 and screwed with a compression nut 4. The sealing washer 3 is specially designed and customized. For different pressure levels and different media, the sealing washer 3 of different materials is selected. An upper pressure block 5 is mounted on the part of the joint main body 1 outside the pipe wall and is screwed with a stop pad 6 and a stop nut 7 .

Abstract

A pipe joint for the meter installed on the pipe wall has a main body with central through hole installed in said hole on the pipe wall. Its internal part projected from the inner surface of pipe wall has sealing washer and pressing nut. Its external part outside the outer surface of pipe wall has pressing block, check washer and check nut. Its advantages are high pressure and leakage resistance,low cost, small size and easy installation of meter.

Description

technical field [0001] The invention relates to a pipe joint, in particular to a pipe joint used for pressure pipe wall instruments. Background technique [0002] Instruments, especially pressure gauges, thermometers, flow meters and other instruments are extremely important components of the pressure piping system, and are the "eyes" of the piping network system. In the traditional pipeline system mainly made of steel pipes, because metal materials have good weldability, pipeline instruments are usually connected to pipelines by welding. [0003] With the development of science and technology, traditional steel pipes are gradually being replaced by new non-metallic pipes due to their strong rigidity, poor corrosion resistance and shock resistance. The successful application of polyethylene (PE) pipes has made it possible for non-metallic pipes to replace steel pipes in the field of pressure pipes, and the birth of steel skeleton polyethylene (SPE) composite pipes has trigg...
