Abstract
The utility model provides an ultrahigh pressure quick-change coupler which at least comprises a female connector and a male connector. The female connector is provided with a cylindric locking sleeve, and the tail part of the locking sleeve is sleeved on the female connector and can rotate on the female connector; screw threads matching with each other are arranged on the male connector and the inner wall of the locking sleeve, and the male connector can be fixed in the locking sleeve through the screw threads. Steel balls, springs and steel ball positioning cores are arranged on both the female connector and the male connector. The steel balls and the springs are installed on the steel ball positioning cores; the steel balls are positioned at the inwardly tapered outlets of the female and male connectors and contact with the inwardly tapered outlets under the actions of the elastic forces of the springs; and the steel balls are partially exposed outside the outlets of the female and male connectors. The ultrahigh pressure quick-change coupler can totally satisfy the application under the working condition with ultrahigh pressure of 120MPa, and has the advantages of reliable connection, convenience in assembling and disassembling operations, high pressure resistance and good sealing performance.
Description
Technical field
The utility model relates to a kind of quick release coupling, is specially the ultrahigh pressure quick release coupling that a kind of working pressure can reach 120MPa, need to be applied in the frequent ultrahigh-pressure hydraulic pipe-line system that connects and break off.
Background technique
The quick release coupling that is connected between (electronic) ultrahigh-pressure hydraulic pump and the Hydraulic power tools (like hydraulic spanner, hydraulic pressure pulley extractor (drawing horse), hydraulic bolt tensioning jack, hydraulic jack etc.) at present manually adopts common quick release coupling mostly.Because the overpressure during these joint work, the steel ball that often takes place on the negative joint is pressed the V-type groove on the swollen male connector, causes joint not throw off; Do not meet the high pressure applying working condition owing to joint structure again simultaneously, the one-way leakage of hydraulic medium when the external leakage of hydraulic medium and disconnection connect when usually causing joint connection work.
Summary of the invention
The utility model provides a kind of ultrahigh pressure quick release coupling, has solved shortcoming of the prior art, and its working stability does not have the leakage of hydraulic medium when connection or disconnection.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of ultrahigh pressure quick release coupling comprises negative joint and male connector at least, and negative joint is provided with cylindric lock sleeve; The afterbody of lock sleeve is set on the negative joint and can on negative joint, rotates; The inwall of lock sleeve and male connector are provided with the screw thread of mutual coupling, and male connector can be fixed in the lock sleeve through screw thread, are equipped with steel ball, spring and steel ball location core in negative joint and the male connector; Steel ball and spring are installed on the core of steel ball location; And steel ball is positioned at the outlet port of the inner conical of the moon/male connector, under the elastic force effect of spring, contacts with the inner conical outlet, and the part of steel ball is exposed to the outlet of the moon/male connector.
Male connector is provided with positioning boss, and positioning boss is positioned at the tail end of screw thread on the male connector.
Circular hole in the top of negative joint is provided with and can the top of male connector be wrapped in is provided with two O-ring seals and two back-up rings in the circular hole.
Steel ball location core is fixed in the moon/male connector through jump ring; Lock sleeve is set on the negative joint through wire circlip.
The ultrahigh pressure quick release coupling that the utility model provides has following advantage: adopt the lock sleeve internal thread to be connected with the male connector outside thread between negative joint and the male connector, guaranteed the reliability when joint connects; This ultrahigh pressure quick release coupling adopts two O-ring seals to add two sealing group of two back-up rings compositions simultaneously, has improved the reliability at high pressure operating mode lower seal, the external leakage when having avoided connecting.A positioning boss is set on the male connector, whether connects and put in place, and the mistake when preventing to be threaded is twisted and damaged so that observe male and female connector; Makes one-way valve with steel ball in negative joint and the male connector, plays the one-way sealing effect, change traditional one-way valve and rely on the structural type that rubber seal seals, the assurance high-pressure liquid through the time do not cause damage to one-way valve.The utility model ultrahigh pressure quick release coupling can satisfy 120MPa ultrahigh pressure operating mode fully and use, and has and connect the excellent advantage such as well of reliable, mounting or dismounting convenience, withstand voltage height, sealability.
Description of drawings
The structural representation of the ultrahigh pressure quick release coupling that Fig. 1 provides for the utility model;
