The dust ring that dust ring 24 uses elastic material to make can prevent from entering the inner dustproof hole of Wear and plug of accelerating Sealing of joint because of dust.
The present embodiment connects: the present embodiment is as negative joint, be fixed on the equipment, the present embodiment is when common male connector with 15MPa pressure is connected, male connector is aimed at the joint of the present embodiment, is forced into, such as Fig. 2, because of fittings body 28 and the intermediate 17 that is connected, outer ring 2 is fixed on the equipment, can't move, and the effect because of retainer back-up ring 21 also can't move inward valve seat retainer 20 again.And the effect of male connector push-on force makes housing 1 move inward simultaneously with the valve seat sliding sleeve 18 that is connected, after housing and valve seat sliding sleeve move to certain position, such as Fig. 3, steel ball 3 slips in the groove on the outer ring 2, make male connector can continue to push, valve core in the push-on process on the male connector pushes up mutually with valve core 6 on the negative joint, because backing down with 15MPa pressure valve core body in the male connector, and be not with pressure in the negative joint, therefore the male connector valve core backs down negative joint valve core 6 and parts, when valve core 6 and parts back down end face 13.1 on the end face 8.1 top valve seats 13 to the position limiting sealed pad pressure ring 8, and the steel ball 19 on the valve seat sliding sleeve 18 slips in the large diameter hole on the valve seat retainer 20 because the 18 inside movements of valve seat sliding sleeve make steel ball 19, makes valve seat be in axial active state.Such as Fig. 4, during public plug further inwardly promotes, the male connector valve core withstands negative joint valve core 6 and the position limiting sealed pad pressure ring 8 that matches on the negative joint valve core 6 offsets with valve seat 13, therefore valve seat 13 is moved inward, male connector continues inwardly to push, slip in the male connector groove to steel ball 3, male connector stops to push, decontrol male connector, spring 9 on the negative joint makes housing 1 and the valve seat sliding sleeve 18 that is connected resets, outer ring 2 endoporus are pushed down steel ball 3, make steel ball 3 fix male connector, male connector is formed with the present embodiment negative joint firmly be connected.
After the present embodiment connects, such as Fig. 4, pass into the fluid higher than male connector pressure in the present embodiment negative joint, such as 20MPa, because of male connector and negative joint fluid pressure differential, such as Fig. 5, valve core 6 and parts on the negative joint are moved to the low male connector direction of pressure, the male connector spool is opened, and fluid is connected, and the present embodiment valve seat 13 is because also moving to the male connector direction under spring 25 and the fluid scouring double action, after moving to jump ring 12 positions, the locking steelball 19 of valve seat 13 slips in the steel bead groove on the valve seat 13, and valve seat retainer 20 is pushed down steel ball 19 automatically because of the effect of spring 16, has fixed the axial position of valve seat 13.
The present embodiment disconnects: such as Fig. 6, coupled condition is carried out force analysis under the simple static pressure state to the present embodiment fluid.Act on being formed by inside motion stress F1, F2 and outside motion stress F3 on the valve seat sliding sleeve 18 among Fig. 6, so inside motion stress=F1+F2-F3, we are called for short FN resulting value, and determined by the institute receiving area according to the pressure size, therefore during can being designed by the present embodiment of FN to the size of 18.1 these faces control FN power size.F4 and F5 produce pair of separated power, and Separating force is according to the transmission of power, be passed to steel ball 3 and outer ring 2 point of contact B by steel ball 3 with male connector point of contact A, make 3 pairs of outer rings of steel ball 2 produce pressure F6, because this F6 is to the pressure of outer ring, when being moved, the outer ring produces frictional force, be called for short FM, and the power of the FN that design is controlled according to the size of 18.1 these faces during the present embodiment makes FN greater than FM, and along with the rising of internal fluid pressure, the difference of FN and FM will further increase, we are called for short FJ with the difference of FN-FM gained, and this power of FJ can make male spigot, housing 1, valve seat sliding sleeve 18 moves inward, can have the effect of spring 9 to produce spring pressure F7 and come this power of balance FJ, make housing 1, valve seat sliding sleeve 18 parts such as grade can't inwardly move.But because F7 is spring pressure, this pressure is steady state value, and FJ can raise along with the rising of internal fluid pressure, so when internal fluid pressure is elevated to certain value, make power that FJ produces greater than spring pressure F7, male and female connector meeting automatic disconnection such as a hydraulic power, connects a plurality of hydraulic pipe lines, want to disconnect pipeline, only need the rising of the pressure in the parts pipeline just can be realized automatic disconnection, and use this joint can play overload protection, can be in the rear automatic disconnection of pressure rising; Manually disconnection only operates under the stress-free state of internal flow, and not so because of the impact of internal fluid pressure, joint can't be movable; Such as Fig. 7, valve seat sliding sleeve 18, housing 1 parts such as grade inwardly move, and along with movement, steel ball 3 slips in the groove of outer ring 2, to making male connector be in active state, and male connector is separated with negative joint.And in the separation process, the valve core in male connector and the negative joint and parts can reset valve core and parts because of hydrodynamic pressure and spring 11 pressure, prevent the fluid outflow in the pipeline.After male connector disconnected, valve core and members close in the negative joint were such as Fig. 8, fluid produces pressure F8 to valve core 6 and parts, and the spring force F7 that the difference of F8+F3 and F1+F2 produces less than spring 9 therefore spring 9 resets, resets drive housing 1, valve seat sliding sleeve 18 and associated components.So far negative joint is replied reset condition.
