管接頭在液壓系統(tǒng)中管接頭起到很重要作用，如果因?yàn)楣芙宇^造成泄漏的話不僅導(dǎo)致效率降低，還會(huì)導(dǎo)致油溫升高、執(zhí)行機(jī)構(gòu)不穩(wěn)定，污染環(huán)境等。甚至直接影響液壓設(shè)備的正常使用，那么如何提高接頭體的密封的可靠性呢？首先我們得要了解卡套式管接頭的密封原理。

Pipe joint plays a very important role in the hydraulic system. If the pipe joint causes leakage, it will not only reduce the efficiency, but also lead to high oil temperature rise, unstable actuator and environmental pollution. Even directly affect the normal use of hydraulic equipment, so how to improve the reliability of the joint [[[body]]] seal? First of all, we need to understand the sealing principle of bayonet type pipe joint.

卡套式管接頭的密封原理

在卡套右端需將螺母擰緊頂壓下，左端被擠進(jìn)接頭體內(nèi)錐孔與管子間的間隙里，使卡套的外錐面形成錐面接觸密封，將卡套的內(nèi)刃口嵌入鋼管外壁，在鋼管的外壁壓出一個(gè)閉口環(huán)槽起切入密封，進(jìn)一步擰緊螺母，使卡套中部稍微凸起，產(chǎn)生彈性變形，彈性應(yīng)力使卡套右端面與螺母錐面產(chǎn)生摩擦力，以防螺母松動(dòng)，彈性變形部分可吸收液壓管道中的震動(dòng)，另外，卡套尾部也緊抱鋼管形成一道抵觸密封。

At the top of the card sets of right side need to tighten nut under pressure, the left is squeezed into the connector [[[body]]] cone hole and the gap between the pipe, the card sets of male cone form taper contact sealing, the card sets of embedded inside edge of the outer wall of steel pipe, in the walls of the pipe pressure out of a cut into the seal ring groove, further tighten the nut, the card sets of central bulge slightly, produce elastic deformation, the elastic stress make the card right face and nut cone produces friction, in case of nut loose elastic deformation part can absorb vibration of hydraulic pipeline, in addition, the card sets of tail also clasp steel pipe forming a seal.
