密閉型高壓橡膠接頭工作原理與特點(diǎn)

密閉型高壓橡膠軟接頭(以下簡(jiǎn)稱自密型接頭)是zui近研制成功的一項(xiàng)科研成果。它的基本原理是運(yùn)用管內(nèi)壓力自行增強(qiáng)密封,*解決了由橡膠被過(guò)量壓縮引起的各種弊病。通過(guò)高溫、低溫、撓曲、脈沖、拉脫力、爆破、耐壓密封、老化、自密等各項(xiàng)試驗(yàn),證明這種軟管接頭除具有*的密封性能外,還具有重量輕、體積小、結(jié)構(gòu)緊湊、連接牢固、通徑大、流阻小、使用壽命長(zhǎng)、用料省、加工簡(jiǎn)易、裝配方便、接頭可多次回收使用等優(yōu)點(diǎn)。

高壓管道連接,必須滿足一定溫度范圍內(nèi)的連接強(qiáng)度和密封性這兩項(xiàng)基本性能要求。對(duì)于高壓橡膠軟管來(lái)說(shuō),還必須考慮接頭對(duì)橡膠的壓縮所引起的老化影響和彈性應(yīng)力松弛等問(wèn)題。目前的高壓橡膠軟管接頭,雖有不少類型,但其基本結(jié)構(gòu)原理都是沿襲了低、中壓橡膠接頭的原理,即依靠芯軸與套管之間的夾緊力來(lái)獲得密封和連接強(qiáng)度。所不同的僅僅是增加了壓緊量和加長(zhǎng)密封面長(zhǎng)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.
