Abstract
The utility model relates to a hydraulic fast joint which is composed of a joint body, a joint sleeve, valve cores, etc., wherein the end face of one valve core has a blind hole in the axial direction, the end face of the other valve core is provided with a short shaft opposite to the blind hole, and the short shaft is completely sheathed in the blind hole. When a valve is connected, the two valve cores are connected. The utility model has good stability and is suitable for pulse working conditions.
Description
The utility model belongs to hydraulic element, is specifically related to hydraulic quick coupling.
At present, the hydraulic quick coupling that uses under mesohigh and pulsation operating mode, two spools only are the both ends of the surface contact.When fluid went out pulsation and connection like this, spool was offset easily, causes the joint instability, and influence connects effect.
The purpose of this utility model is a concave-convex connection structure at a kind of spool of design, to overcome the deficiency of above-mentioned rapid pipe joint.
The technological scheme of this hydraulic quick coupling: comprise fittings body and/or joints sleeve, joints sleeve spring, positioning ball, spool, valve core spring.A spool end is established blind hole vertically in two spools, and the relative blind hole of another spool end place establishes minor axis, and minor axis is placed in fully educates in the hole.When this valve connected, two spools were connected.Its good stability is suitable for the operating mode of pulsing.
