液压管接头，液压系统中，连接高压油管与高压油管之间的部件。

Hydraulic pipe fittings, hydraulic system, the connection between the high-pressure oil pipe and high pressure pipe components.

管接头的分类：

Classification of pipe joints:

高压球阀、快速接头、卡套式管接头、焊接式管接头、高压软管。 过渡式管接头、卡套式管接头、三通式管接头、非标式管接头、扩口式管接头、直角式管接头、旋转式管接头、快速接头、不锈钢管接头、铜接头。

High pressure ball valve, quick connector, ferrule type pipe joint, welded pipe joints, high pressure hose. Transition type pipe joint, clip sleeve type pipe joint, three type pipe joint, non-standard pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, quick joint, stainless steel pipe joint, copper joint.

液压管接头和普通管接头的差别：

The hydraulic pipe fittings and pipe joint common difference:

最大的最显著的区别的就是液压的压力是大的惊人的，液压油管突然爆裂油的冲击力是很大的。

The biggest and most significant difference is that the hydraulic pressure is big, amazing, the hydraulic tubing suddenly burst, the impact force of oil is very large.

不能用普通的替换专用的接头，因为液压的都是可以承受很大压力的，普通的最多0.5个气压就已经快不行了。

Can not use ordinary replacement special joints, because the hydraulic pressure can be under great pressure, the ordinary up to 0.5 air pressure has been almost impossible.
