Examples

As shown in fig. 3-9, the water valve mechanism of a coupler includes a water feeding conduit 8, a water outlet conduit 3, a silicone sleeve 7, a sealing member 6, a pushing member 5, a spring 4 and a cover 1, wherein the water feeding conduit 8 and the water outlet conduit 3 are both hollow structures, one end of the water feeding conduit 8 extends into the water outlet conduit 3, the sealing member 6 is disposed in the water outlet conduit 3 and can freely move in the water outlet conduit 3, the silicone sleeve 7 is disposed between the water feeding conduit 8 and the water outlet conduit 3, the valve is in a closed state when the sealing member 6 acts on the silicone sleeve 7, the pushing member 5 acts on the sealing member 6, the pushing member 5 is movably fitted in the water outlet conduit 3, the sealing member 2 is disposed between the cover 1 and the water outlet conduit 3, the sealing member 2 is provided with a cutting groove, the cutting groove is a cross cutting groove, which is equivalent to a cross silicone valve, and can be opened by applying pressure, the sealing gasket 2 is made of silica gel, a supporting mechanism for supporting the sealing gasket 2 is arranged on the water outlet conduit 3, the supporting mechanism is arranged for sealing the sealing gasket 2 in a single direction, so that the sealing gasket 2 can be opened only when the sealing gasket 2 is pressed from one end of the water outlet conduit 3, when the sealing gasket 2 is pressed from one end of the cover body 1, the cutting groove of the sealing gasket 2 cannot be opened due to the fact that the sealing gasket 2 is supported by the supporting mechanism, and therefore the sealing gasket 2 is in a closed state when the sealing gasket is pressed in the direction, and the purpose of one-way sealing is achieved.

Supporting mechanism for locating the splice bar 31 on the play water pipe 3, splice bar 31 upper surface flushes with the upper surface of play water pipe 3, and closely laminate with sealed pad 2, splice bar 31 is meter font structure in this embodiment, also can be for other shapes, need reserve the through-hole that supplies liquid to flow through between splice bar 31 can, 4 one end of spring and 31 internal surface butt of this splice bar, splice bar 31 and play water pipe 3 formula structures as an organic whole in this embodiment, all adopt the plastics material to make, spring 4 can be traditional metal relatively when contacting with splice bar 31 and the noise of metal contact is less.

The sealing gasket 2 is clamped between the cover body 1 and the water outlet conduit 3, and a horizontal displacement positioning mechanism for limiting the horizontal displacement of the sealing gasket 2 is arranged between the water outlet conduit 3 and the sealing gasket 2. The horizontal displacement positioning mechanism in this embodiment includes the protruding card 32 that locates the terminal surface of water outlet pipe 3 and protrudes from this terminal surface, is equipped with the draw-in groove 21 that supplies the protruding card 32 embedding on the water outlet pipe 3 on the sealed pad 2 that corresponds, and the sealed pad 2 of restriction horizontal direction displacement on water outlet pipe 3 of the protruding card 32 and the cooperation of draw-in groove 21. The arrangement of the horizontal displacement positioning mechanism can ensure the position fixation of the sealing gasket 2, thereby avoiding the situation that due sealing effect cannot be achieved due to dislocation. In this embodiment, the two sets of locking protrusions 32 and the locking grooves 21 are provided, so that a better positioning effect can be achieved. The height of the clamping protrusion 32 should be smaller than the thickness of the sealing gasket 2, so that the sealing gasket 2 cannot be displaced in the axial direction of the water outlet pipe 3, and the sealing effect is ensured.

The outer diameter of one end of the spring 4, which pushes the sealing piece 6, is smaller than that of the other end, a conical part is formed at the local part of the spring 4, and the two ends of the spring 4 are in a straight-tube structure. Set up straight barrel construction with spring 4 both ends, wherein one end spring 4 external diameter slightly is less than the internal diameter of play water pipe 3, guarantee that spring 4 can imbed out in the water pipe 3 and can not be good at play water pipe 3 internal radial displacement, other end spring 4 external diameter is little for pushing away sealing member 6 that can be better, relatively level and smooth like this, can increase spring 4's stability can, with spring 4 external diameter and play water pipe 3 assorted one end be in order to prevent that spring 4 can not produce the displacement in play water pipe 3. Go up spring 4 and change the toper structure into, change straight tubular construction in the past, in the middle of the process of drawing water, can not swing in 3 the inside of the water outlet pipe, after stopping the water injection, the driving force stationarity of spring 4 can not swing because of the space is too big, leads to 4 dynamics of spring not enough even, causes sealing member 6 (steel ball) to seal firm inadequately.

The silicone rubber cover 7 described in the present embodiment includes an outer sealing portion 71 and an inner sealing portion 72, and an end of the outer sealing portion 71 has a mouth sealing portion 711; the mouth portion seal portion 711 abuts against the seal member 6 to form a seal. A housing 73 is formed between the outer seal portion 71 and the inner seal portion 72, and the housing 73 communicates with the mouth seal portion 711 of the outer seal portion 71. The accommodating portion 73 is an annular groove. A cross-cut diaphragm 721 is arranged at the mouth of the inner sealing part 72, and the diaphragm and the silica gel sleeve are of an integrated structure. The inner wall of the outer sealing part 71 is provided with a convex part 712 which is arranged to be convex inwards, and an inwards concave arc-shaped surface part 713 which is attached to the surface of the sealing member 6 is arranged between the convex part 712 and the mouth of the outer sealing part 71. The outer wall of the outer sealing part 71 is provided with a bending part 714, and the bending part of the bending part 714 is of an arc structure; the surface of the protruding portion 712 has a rounded structure. In this embodiment, silica gel cover 7 installed in the upper pumping valve is technically improved, silica gel is soft after the silica gel cover is used for a period of time in the background art, a sealing effect cannot be achieved, partial water leakage is caused, and the service life is short. So that the steel ball can be better matched with the steel ball. In the embodiment, a bent part 714 is arranged on the outer wall of the outer sealing part 71, the bent part of the bent part 714 is of an arc-shaped structure, and the bent part 714 is also arranged at the position in the background art, but a straight-line bent structure is adopted, the bent part 714 of the embodiment is improved into the arc-shaped structure, the bottom of the bent part 714 is wide, and the bent part plays a supporting role and cannot be soft due to long service time; and the middle of the internal sealing part 72 in the background art is a through hole, the through hole is designed into a layer of thin rubber (namely a cross silica gel valve) in the embodiment, a cross opening is cut at the center of the rubber, when water is supplied, the thin rubber is flushed by water pressure, when the water injection is stopped, the steel ball returns to the original position, the water inlet is sealed, the water cannot flow back, a function is added on the function, the thin rubber is closed, so that the secondary sealing effect is achieved, and the anti-overflow effect is better ensured.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
