Description
Technical field
The utility model is related to a kind of valve pipe fittings.
Background technology
Valve is widely used in the hydraulic system pipeline in the fields such as engineering machinery, oil with pipe fitting, in system work shape
Being quickly engaged and separating for hydraulic system pipeline is carried out under state, realizes being switched fast for system.Existing structure easily causes sealing and loses
Effect, maintenance cost are higher.
Utility model content
Technical problem to be solved in the utility model is：A kind of valve pipe fitting, this kind of valve pipe fitting are provided
It can guarantee for a long time using sealed reliable, reduce maintenance cost.
The technical problem is solved, the technical solution of the utility model is：A kind of valve pipe fitting, by major joint,
Sub-joint and sleeve composition, sub-joint put in major joint, and sleeve coordinates respectively with major joint and sub-joint, the structure of sub-joint with
Major joint is identical, and major joint includes spool, spring base, sealing ring and clamp spring, is provided on the spool along major joint axis
The major joint relief hole of direction arrangement, spring base are located at major joint relief hole side, and one end of spring base has sealing ring, bullet
The other end of spring abutment has clamp spring, and sub-joint has sub-joint relief hole, and extended line and the master of sub-joint pressure release centerline hole connect
Head pressure release centerline hole overlaps.
The major joint relief hole and the shape of sub-joint relief hole are bellmouth, the major joint relief hole and
The direction of sub-joint relief hole bellmouth is opposite.
The major joint relief hole and the taper of sub-joint relief hole are 75 degree.
A kind of valve of the utility model, using such structure, can guarantee for a long time using sealed reliable, drop with pipe fitting
Low maintenance cost.
