When not having external force, the water inlet slide block is under the promotion of first spring, press close to the into top of water cover, the first portion of water inlet slide block enters the butt joint stream socket, the selfsealings face formation of the butt joint stream socket of first seal ring and water inlet cover is tightly connected, realizes the sealing between slide block, seal ring, the butt joint stream socket internal surface.Form sealing by seal ring with docking stream socket though be depicted as the first portion of water slide block in the drawings, the water inlet slide block with dock stream socket and can realize direct sealing.At this moment, the first portion of the slide block of for example intaking forms the cross section conical surface, and the internal surface of butt joint stream socket also forms the corresponding reciprocal cross-section conical surface, thereby the water inlet slide block can be under the promotion of first spring, and dock stream socket and forms and seal.The first portion of water inlet slide block has formed interior interface.
When docking with the water outlet slide block, as shown in Figure 9, the water inlet slide block is subjected to the power that applies from interior interface, compresses first spring and slides along the inwall of water inlet cover, makes UNICOM between the pipe interface of the docking port of water cover into and water inlet base.
The external sealed face of groove that second spring, lock ring, water inlet put and water inlet cover has become the interconnected sealing configuration of water supply connector.
Second spring and lock ring are installed between the middle part projection of water base into and water inlet cover, and the lock ring inwall has projection, are blocked in water outlet base one side by the projection of water inlet cover on the one hand, on the other hand as the attachment face of spring.Second spring just is installed in between the water base and lock ring inwall projection, and lock ring can be done limited moving to the base direction at the promotion lower compression spring of external force.The front end of water inlet cover has a groove.Cooperation between the interconnected sealing configuration of the interconnected sealing configuration of water supply connector and water output connector is described below in conjunction with the explanation to water output connector.
As Fig. 8 B, according to a kind of mode of execution of the present utility model, water output connector comprises: the water core of hollow, water outlet slide block, go out water jacket, snap ring, the 3rd spring, second seal ring (2), the 3rd seal ring and steel ball (for example circumference uniform distribution is 3).
There is side opening (butt joint fluid passing hole) and the inner UNICOM that is uniformly distributed along the circumference on the water core top, and the other end of water core has pipe interface.Water core with go out water jacket and fixedly connected, for example can interconnect by sealing thread.Going out between water jacket and the water core to form hollow space.
Water outlet slide block and water core are installed with one heart, can move along the water core outer wall, water outlet slide block and go out the spring that concentric installation is arranged between the water jacket, snap ring is installed in out on the inwall of water jacket, purpose is the sphere of activities of restriction water outlet slide block, and it can not slided into outside the water core.Should be noted that snap ring also can be installed on the water core, the sliding scale of restriction water outlet on the outlet core can not slide into outside the outlet core it.
The sealing of water output connector is by second seal ring (2) sealing of water outlet slide block inboard.When being in off state, the 3rd spring promotes the top that the water outlet slide block moves to water core.Two seal rings are realized sealing, shown in Fig. 8 D just in time in the both sides of osculum.Also be formed with the external sealed face on the water outlet slide block.
When the disconnecting device docked, at first intake cover and water outlet slide block were docking together whole mobile, and external sealed face that water inlet puts and the external sealed face on the water outlet slide block pass through the 3rd seal ring and form sealing.Water core head and the butt joint of water inlet slide block are together to continuing motion then.As shown in Figure 9, motion result is: on the one hand, the head of water core withstands into water slide block, enters into water cover inside, has exposed the butt joint fluid access hole on the water core, thereby has formed the butt joint between the butt joint.
On the other hand, the water inlet cover withstands the water outlet slide block, pushes ahead, and enters into out the inside of water jacket.Because bead diameter is greater than the wall thickness that goes out water jacket, in docking operation, pearl is projected into out outside the water jacket wall, stops lock ring, moves behind the lock ring.Continue to push ahead, when pearl enters the groove that water into puts, under the effect of lock ring thrust, take in the pearl into groove, the lock ring resistance disappears, and lock ring moves right under the promotion of second spring, cover pearl, make it to break away from groove, the butt joint of disconnecting device is locked.
In the time will disconnecting being connected of water supply connector and water output connector, pull back lock ring, the groove raceway groove that goes out the pearl disengaging water inlet cover in the water jacket discharges, the release of disconnecting device, first spring promotes the water inlet slide block and moves to water inlet cover top, the 3rd spring promotes the tip motions of water outlet slide block to water core, and water output connector and water supply connector disconnect naturally.
In the above example, as preventing the water outlet slide block and go out separated structures between the water jacket, but can adopt other parts, put the projection of appropriate location etc. as water outlet by snap ring.In addition, in the above example,, but also can adopt other parts with the parts of steel ball as interconnected usefulness.In the above example, on the inwall of water inlet cover, form the external sealed face, and on the outer wall of water outlet slide block, form corresponding external sealed face, but also can on the outer wall of water inlet cover, form the external sealed face, and going out to form corresponding external sealed face on the inside of water jacket.The method and structure of the line seal after forming butt joint in a word and making butt joint is a lot, can adopt variety of way.
