Abstract
The utility model provides an automatic pressure relief quick-change connector which at least comprises a female connector, a male connector as well as two valve cores which are respectively positioned in the female connector and the male connector; top ends of the two valve cores are provided with hollow protrusions, and the positions of the two protrusions are corresponding mutually; hollow cavities of the two protrusion are communicated with a pipeline; the top of each protrusion is provided with a through hole; each hollow cavity is internally provided with a sealing element; springs are arranged between the sealing elements and the valve cores; the seal elements are in contact with the through holes under the elastic force effect of the springs and seal the valve cores; and one part of the each sealing element extends out of each protrusion from the through holes, and the dimensions of the parts positioned outside of the protrusions are less than the dimensions of the inner parts of the protrusions. The automatic pressure relief quick-change connector not only is convenient to use, but also has long service life.
Description
Technical field
The utility model relates to a kind of quick release coupling, and being mainly used in needs in the frequent hydropneumatic system pipeline that connects and break off.
Background technique
The present quick release coupling that especially uses on the oil hydraulic cylinder in the steel ladle sliding water gap mechanism of metallurgy industry; After quick release coupling is thrown off; The male connector that is installed on the oil hydraulic cylinder and is communicated with it; Receive the temperature of ladle and the influence of slide gate mechanism deadweight, the pipe interior of male connector produces back pressure, gives to connect once more and causes difficulty.In use at present, generally adopt hammer and round steel to knock spool, the hydraulic medium in the male connector is flowed out, thereby release the residual voltage in the male connector, and then negative joint is connected connection with male connector.Not only use inconvenience, and spool is knocked also be prone to the damage that makes spool too early for a long time.
Summary of the invention
The utility model provides a kind of releasing pressure automatically quick release coupling, has solved existing joint and has used shortcomings such as inconvenient, that the spool rapid wear is fast.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of releasing pressure automatically quick release coupling comprises negative joint, male connector and lays respectively at negative joint and two spools of male connector inside that the top of two spools is equipped with the convexity of hollow shape at least; And the position of two convexities is corresponding each other; Protruding hollow cavity and pipeline connection, protruding top is provided with a through hole, is provided with a Sealing in the hollow cavity; Be provided with spring between Sealing and the spool; Sealing under the elastic force effect of spring, contacts with through hole and with seal spool, the part of Sealing is stretched out in protruding outside by the through hole, and is positioned at protruding outside size less than protruding inner size.
Convexity is the cylindrical hollow pipe, and is positioned at the center on spool top.Sealing is a steel ball.
The releasing pressure automatically quick release coupling that the utility model provides has following advantage: steel ball pressure relief device of design on the spool; When male connector inserts the negative joint connection; The steel ball on two spool tops contact earlier backs down, and discharges a small amount of hydraulic medium, promptly releases the inner residual voltage of quick release coupling; This moment, two spools can normally be opened, thereby guaranteed the proper functioning of quick release coupling.
Description of drawings
The coupled condition schematic representation of the releasing pressure automatically quick release coupling that Fig. 1 provides for the utility model;
The off state schematic representation of the releasing pressure automatically quick release coupling that Fig. 2 provides for the utility model;
Among the figure, 1-male connector seat, 2-valve core spring, 3-spool, 4-male connector, 5-spring, 6-steel ball, 7-lasso steel ball, 8-O shape seal ring, 9-lasso, 10-D shape seal ring, 11-negative joint, 12-negative joint seat.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The structure of the releasing pressure automatically quick release coupling that the utility model provides is as depicted in figs. 1 and 2, by negative joint 11, male connector 4 and lay respectively at negative joint 11 and male connector 4 in spools 3 form.Negative joint 11 is installed on respectively on negative joint seat 12 and the male connector seat 1 with male connector 4.The top of negative joint 11 is a lasso 9; Lasso 9 is fixed on the negative joint 11 through wire circlip, and lasso 9 has lasso steel ball 7, when negative joint 11 is connected with male connector 4; Lasso steel ball 7 snaps in the V-shaped groove on the male connector 4, and male connector 4 can't be withdrawed from negative joint 11.
Also be provided with O-ring seals 8 in the negative joint 11, O-ring seals 8 is positioned between the two when male connector 4 is connected with negative joint 11, prevents the outer leakage of hydraulic medium.
Spool 3 is fixed in the moon/male connector, and its rear is equipped with valve core spring 2.The outlet port of negative joint 11 and male connector 4 is provided with D shape seal ring 10, thereby spool 3 can be under the elastic force effect of valve core spring 2 contacts the sealing of realization the moon/male connector with D shape seal ring 10.
The top of two spools 3 is equipped with the convexity of hollow shape, and the position of two convexities is corresponding each other, all is positioned at the center on spool 3 tops, protruding hollow cavity and pipeline connection, and convexity is the cylindrical hollow pipe in the present embodiment.Protruding top is provided with a through hole, is provided with a Sealing in the hollow cavity, is provided with spring 5 between Sealing and the spool, and Sealing contacts with through hole under the elastic force effect of spring 5 and spool 5 is sealed.The part of Sealing is stretched out in protruding outside by the through hole, and is positioned at protruding outside size less than protruding inner size.Sealing is a steel ball 6 in the present embodiment, and Sealing also can be selected round platform for use.
The working principle of the releasing pressure automatically quick release coupling that the utility model provides is following: when male connector inserts negative joint and connects; Steel ball in the two spool top convexities contacts earlier and backs down; Discharge a small amount of hydraulic medium, promptly release the inner residual voltage of quick release coupling, two spools move backward with D shape seal ring and break away from simultaneously; Open the conical outlet in the joint, guarantee passing through of fluid.The lasso steel ball is pressed in the V-shaped groove of male connector under the effect of ferrule spring simultaneously, easily connects hydraulic pipe line.When needs broke off joint, pulled backwards lasso, spool compressed sealing with the D shape seal ring at the conical outlet place of male and female connector under the valve core spring effect, and steel ball is under spring action simultaneously, and with the through hole sealing, working medium does not outflow when guaranteeing to break off.
