Problems solved by technology

[0002] Among the existing pipeline fixing parts, welding is basically used for fixing, and the welding method has the following disadvantages: (1) High cost: using welding technology, professional welding personnel are required, and reinstallation after disassembly is time-consuming; (2) Easy to crack, poor sealing, short service life: the welding process is adopted, the rigidity of the joint between the fixing part and the pipe is high, and it is easy to crack after being subjected to high pressure or multiple cycles of pulse pressure, resulting in poor sealing and use short life

Abstract

The invention provides a fixing part, comprising a body and a boss, wherein the body is of a hollow structure and comprises a front end and a tail end; the boss is arranged on the outer wall of the front end and comprises an L-shaped side face formed by a first side face and a second side face; a bulge facing to the tail end is arranged on the top end of the first side face; the bulge, the first side face and the second side face form a first groove; the height of the bulge is one fifth to three fifths of the width of the second side face; a matching face is milled in the second side face. After the technical scheme is applied, since the design of the first groove is adopted, and a seal ring is used for sealing the first groove, the anti-pressure capability is strong, and the seal performance is good; no professional and technical personnel are needed, so that the cost is low; the matching face is milled in the periphery of the second side face, the fixing part is tightly matched with other devices in the using process, the rotation is prevented, and the seal performance is good.

Description

technical field [0001] The invention relates to the field of pipe fixing parts, in particular to a fixing part for fixing water heater pipes with good sealing performance and long service life. Background technique [0002] Among the existing pipeline fixing parts, welding is basically used for fixing, and the welding method has the following disadvantages: (1) High cost: using welding technology, professional welding personnel are required, and reinstallation after disassembly is time-consuming; (2) Easy to crack, poor sealing, short service life: the welding process is adopted, the rigidity of the joint between the fixing part and the pipe is high, and it is easy to crack after being subjected to high pressure or multiple cycles of pulse pressure, resulting in poor sealing and use Short life. [0003] Therefore, it is of great value to invent a fixture for pipelines with low cost and good sealing effect. Contents of the invention [0004] The purpose of the present inv...
