Abstract
Disclosed is a hydraulic quick change flat head connector structured by a male connector (1) and a female connector (2). A movable valve core (3) is equipped in the male connector (1), and the female connector (2) comprises a fixed valve core (4), a ferrule(5), a top sleeve(6), a movable sleeve(7) and steel balls(8); the back end of the movable part of the moveable valve core (3) in the male connector (1) is a cone-shaped body(9) whose outer wall contacts the inner wall of the male connector with sliding fit. A diversion hole (10) is opened on the bevel of the cone-shaped body (9); a concave bore is provided in the front part of the movable valve core (3) and a salient corresponding to the concave bore is provided in the front part of the fixed valve core (4) in the female connector (2), a safe pin is arranged on the female connector (2). As a plane valve structure is adopted by the hydraulic quick change flat head connector, air and dirt entering into the hydraulic pipeline is avoided when connecting the connector. The sliding fit between the movable valve (3) and inner mouth of the male connector (1) offers a guiding performance. The movable valve (3) will accurately reset due to the action of a spring force when the female connector and the male connector separate, thereby avoiding the leakage of the liquid in the pipeline.
Description
Affiliated technical field
The utility model relates to the joint of metallurgical equipment hydraulic pipe line, especially has the quick change coupling head of cut-off device.
Background technique
At present, the self-styled valve of the quick release coupling that the metallurgical equipment hydraulic pipe line uses is mitre velve, the male and female connector jointing end face protrudes, during connection, the male connector body inserts the negative joint body, and self-styled valve backs down, connect hydraulic circuit, in the male connector body insertion process, in joint, form a negative pressure space, thereby cause air to suck.The pulling lasso, quick release coupling male and female connector body is thrown off, self-styled valve is under the spring force effect, unidirectional closing, and self-styled valve motion guide is to rely on the interior spring seat that cooperates of male and female connector body to realize, guidance quality is poor, and self-styled valve can not seal with male and female connector body inner sealing surface well, causes the leakage of liquid in pipe.
Summary of the invention
In order to overcome the deficiency of existing quick release coupling, the utility model provides a kind of hydraulic pressure tack quick release coupling of improved type, makes movable spool have good guidance quality, and accurate positioning during the contact of male and female connector body end face, contact are closely.
The technological scheme that its technical problem that solves the utility model adopts is that hydraulic pressure tack quick release coupling is made up of male connector and negative joint, is equipped with movable spool in the male connector, under the effect of spring, when male and female connector disconnects, automatically oil circuit is sealed; Negative joint then is made up of fixed spool, lasso, top cover, movable sheath, steel ball, lasso is under the effect of ARTIFICIAL FORCE, male and female connector is connected and separate, the rear end that is in the active part of the movable spool in the male connector body is the taper shape, its outer wall contacts with male connector body inwall, for being slidingly matched, on the inclined-plane of taper, have pod apertures, so that liquid passes through smoothly; Front end at movable spool is provided with a shrinkage pool, and is corresponding with it, and the front end that is positioned at the fixed spool of negative joint body has a projection, match with the shrinkage pool of movable spool front end in its shape and position, under coupled situation, the projection of fixed spool front end is positioned among the shrinkage pool of movable spool front end; The negative joint body is provided with safety pin, and male and female connector connects the back and rotates lasso, by safety pin lasso is fixed, and prevents that lasso from sliding, and causes joint UNICOM mistiming to be thrown off.
The beneficial effects of the utility model are, because hydraulic pressure tack quick release coupling adopts the plane valve arrangement, its spool front end is provided with shrinkage pool and projection, accurate positioning during connection, contact closely, the mating face of fixed spool and movable spool is concordant with male and female connector body end face, and the air dirt enters hydraulic pipe line when having avoided UNICOM.Movable spool and male connector body endoporus are for being slidingly matched, and guidance quality is good, and when male and female connector disconnected, movable spool accurately resetted under the spring force effect, had avoided the leakage of liquid in pipe.
