Tapered sealing pipe connector for excavator

Abstract

The invention discloses a tapered sealing pipe connector for an excavator. The tapered sealing pipe connector comprises a connector body, a nut, a first connection pipe, a sleeve and a second connection pipe. The connector body comprises a big pipe segment, a small pipe segment and a bent pipe segment. The connector body is formed by sequentially connecting the small pipe segment, the bent pipe segment and the big pipe segment. The small pipe segment is connected with the second connection pipe. The joint of the small pipe segment and the second connection pipe is sleeved with the sleeve. The big pipe segment is connected with the first connection pipe through the nut. The big pipe segment is a segment of straight pipe. The outer ring of the tail end of the straight pipe is provided with external threads. A tapered opening is formed in the big pipe segment. The big end of the tapered opening faces the outer end of the connector body. The first connection pipe is provided with a first O-shaped sealing ring. The small pipe segment comprises a mounting head, a groove and a ladder axial segment. According to the tapered sealing pipe connector for the excavator, through tapered sealing connection, sealing performance can be well achieved, connection can be achieved quickly and conveniently, the connection part is made to be even in stress and not prone to damage and cracking, stability is improved, service life is prolonged, airtightness is good, safety performance is high, and the tapered sealing pipe connector is convenient to assemble.

Description

【Technical field】 [0001] The invention relates to the technical field of connecting pipe fittings manufacturing, in particular to the technical field of cone-sealed pipe joints for excavators. 【Background technique】 [0002] Pipe fittings are a general term for components that play the roles of connection, control, direction change, diversion, sealing, support, etc. in the pipeline system. They are an important part of connecting pipes to pipelines. , flange fittings and welded fittings four categories. Pipe fittings are mostly made of the same material as pipes, including elbows, flanges, tees, crosses, and reducers. [0003] Pipe fittings are generally used to transmit fluid. In order to prevent fluid leakage, it is generally required to be seamlessly connected between pipe fittings. Install or wrap sealing material at the joint, when the pipe end is threaded, there must be a matching device, and when the flange is connected, many accessories are required. [0004] The ...

AI Technical Summary

Problems solved by technology

The hydraulic system of the excavator needs to be connected to the cone seal pipe. The existing cone seal pipe joints have insufficient sealing performance, poor versatility, inconvenient disassembly and assembly, and are subject to many restrictions in use.
