密闭型高压橡胶接头工作原理与特点

密闭型高压橡胶软接头(以下简称自密型接头)是zui近研制成功的一项科研成果。它的基本原理是运用管内压力自行增强密封,*解决了由橡胶被过量压缩引起的各种弊病。通过高温、低温、挠曲、脉冲、拉脱力、爆破、耐压密封、老化、自密等各项试验,证明这种软管接头除具有优越的密封性能外,还具有重量轻、体积小、结构紧凑、连接牢固、通径大、流阻小、使用寿命长、用料省、加工简易、装配方便、接头可多次回收使用等优点。

高压管道连接,必须满足一定温度范围内的连接强度和密封性这两项基本性能要求。对于高压橡胶软管来说,还必须考虑接头对橡胶的压缩所引起的老化影响和弹性应力松弛等问题。目前的高压橡胶软管接头,虽有不少类型,但其基本结构原理都是沿袭了低、中压橡胶接头的原理,即依靠芯轴与套管之间的夹紧力来获得密封和连接强度。所不同的仅仅是增加了压紧量和加长密封面长度。

Working principle and characteristics of closed high pressure rubber joint

Closed type high pressure rubber flexible joint (hereinafter referred to as the self sealing type) is a recent development of a successful research results. Its basic principle is to use the tube pressure to enhance the seal, compley solve the problem caused by excessive compression rubber. The high temperature, low temperature, deflection, pulse, pull-out force, blasting, pressure seal, aging, self sealing of the test that the hose joint except with excellent sealing performance, but also has light weight, small volume, compact structure, firm connection, large diameter, small flow resistance, long service life, material saving, simple processing, convenient assembly, joint can be recycled for many times to the use of the advantages of using.

High pressure piping connections must meet the two basic requirements of the strength and tightness of the connections within a certain temperature range. For high pressure rubber hose, it is necessary to consider the influence of the joint on the compression of the rubber and the elastic stress relaxation. The high pressure rubber hose joints, although there are many types, but the basic structure and principle are followed the low, medium pressure rubber joint principle, which rely on core shaft between the sleeve and the clamping force to obtain sealing and bonding strength. The difference is only the increase of the pressure and the length of the sealing surface.
