The outer wall of the third annular wall 42 is provided with a first step surface 421 facing the bowl opening direction of the element body 41, a third through hole 422 penetrating the element body 41 is formed in the third annular wall 42, and the outer diameter of the third through hole 422 is matched with the outer diameter of the cylindrical rod body 12 of the dismounting rod 1.

The throttling element 5, as shown in fig. 1, is an annular elastic member having an outer diameter adapted to the diameter of the circle enclosed by each second protrusion 3122 in the annular wall 312 of the valve cover 3 and an inner diameter adapted to the outer diameter of the second annular wall 32.

As shown in fig. 1, the elastic element 6 is a spring, which is sleeved outside the dismounting rod 1, and one end of the elastic element abuts against the first protrusion 15, and the other end of the elastic element extends into the second annular wall 32 to abut against the hole shoulder.

The engaging member 7, as shown in fig. 8, has a substantially E-shaped ring structure and is engaged with the first engaging groove 14 of the dismounting rod 1.

As shown in fig. 1, the sealing ring 8, which is of an annular structure, is sleeved on the annular groove 211 of the valve housing body 21.

In this embodiment, as shown in fig. 9, the throttling element 5 is first mounted on the valve cover 3, and the throttling element 5 is sandwiched between each second protrusion 3122 on the annular wall 312 of the valve cover 3 and the outer wall of the second annular wall 32. The elastic element 6 is then fitted over the cylindrical body 12 of the dismounting rod 1 so that one end thereof abuts against the first projection 15 of the dismounting rod 1. Then, the end of the dismounting rod 1 provided with the clamping hole 13 is away from the free end of the second annular wall 32, and the other end of the dismounting rod 1 extends into the second through hole 321 of the second annular wall 32 from the free end of the second annular wall 32, so that the first protrusion 15 is positioned in the second through hole 321 and is in sealing fit with the second through hole 321, and the first clamping groove 14 penetrates out of the second annular wall 32. The other end of the elastic member 6 abuts against the shoulder of the valve cap 3. Then, the clamping member 7 is clamped on the first clamping groove 14, and the part of the clamping member 7, which is exposed out of the first clamping groove 14, abuts against the surface of the valve cover 3, which is away from the second annular wall 32. Then, the end of the dismounting rod 1 provided with the gripping hole 13 is inserted into the third through hole 422 of the elastic ratchet 4, and the first step surface 421 of the elastic ratchet 4 is abutted against the free end of the second annular wall 32, so that the free end of the third annular wall 42 of the elastic ratchet 4 is inserted into the second through hole 321 and abutted against the first protrusion 15 of the dismounting rod 1. Then, the open end of the valve housing 2 is covered on the valve cap 3 at the side of the valve cap 3 where the second annular wall 32 is provided, so that the locking protrusion 3121 of the valve cap 3 is locked and matched with the second locking groove 213 of the valve housing 2, and the end of the dismounting rod 1 where the clamping hole 13 is provided penetrates into the first through hole 221 of the first annular wall 22. The free ends of the first annular wall 22 and the second annular wall 32 are opposite to each other, and the first through hole 221 and the second through hole 321 jointly form a slideway of the dismounting rod 1. Because the outer diameters of the first bulge 15 and the cylindrical rod body 12 on the dismounting rod 1 are different, in order to make the slide better fit with the dismounting rod 1, the slide is divided into a first annular wall 22 and a second annular wall 32 with different inner diameters, so that the forming is convenient; one end of the valve rod provided with the clamping hole 13 extends out of the first through hole 221 of the valve shell 2, the free end of the first annular wall 22 abuts against one side of the elastic non-return member 4, which is far away from the second annular wall 32, and the second abutting surface 212 in the valve shell 2 abuts against the part, close to the second abutting surface 212, of the elastic non-return member 4; finally, the sealing ring 8 is mounted on the annular groove 211 of the valve housing 2.

In the embodiment, when the valve is used, the valve is integrally arranged in a pipeline which needs to prevent backflow, and when the valve is assembled, as shown in fig. 9, in an initial state, the clamping piece 7 is abutted against the surface of the valve cover 3, which is far away from the second annular wall 32, and one end of the dismounting rod 1, which is provided with the clamping hole 13, extends out of the valve core; if other parts need to be installed at the end of the dismounting rod 1 extending out of the valve core, as shown in fig. 10, the parts abut against and press the dismounting rod 1 to enable the first protrusion 15 to compress the elastic part 6, so that the end of the dismounting rod 1 provided with the clamping hole 13 moves towards the inside of the slide way, the length of the end of the dismounting rod 1 provided with the clamping hole 13 extending out of the valve core is adjusted, and the influence on the installation of other parts and the valve caused by the dismounting rod 1 is avoided.

As shown in fig. 11 and 12, when water flows into the first water passing opening 214, the elastic stopping member 4 is deformed under the impact of water pressure and is away from the second abutting surface 212 to form a water passing gap, and the water can flow from the first water passing opening 214 to the second water passing opening 3111. when the water flows to the second water passing opening 3111, the throttling element 5 is deformed under the action of the water pressure, so that the water passing gap formed by the throttling element 5 and two adjacent second protrusions 3122 on the valve cover 3 and the throttling element 5 is reduced for throttling, and the larger the water flow, the larger the deformation degree of the throttling element 5 is, and the smaller the water passing gap formed by the throttling element 5 and two adjacent second protrusions 3122 on the valve cover 3 and the throttling element 5 is. When water in the pipe flows into the valve from the second water passing port 3111, the elastic check member 4 always abuts against the second abutting surface 212, so as to block the communication between the second water passing port 3111 and the first water passing port 214. The valve therefore restricts the flow of water only from the first port 214 to the second port 3111; it should be understood that the direction of the unidirectional flow required in the pipeline can be accommodated by changing the mounting direction of the valve.

As shown in fig. 9 and 10, when the valve needs to be disassembled, if other parts are not installed at the extended end of the disassembling rod 1 on the valve, and at this time, the clamping piece 7 abuts against the surface of the valve cover 3 deviating from the second annular wall 32, the whole valve can be disassembled from the pipeline by pulling the disassembling rod 1 with a tool or by hand; if other spare parts have been installed to the one end that the dismounting rod 1 stretched out on the valve, then at first with other spare parts dismantlement backs, elastic component 6 pushes away the first arch 15 of dismounting rod 1 under the effect of restoring force for dismounting rod 1 is equipped with the one end of pressing from both sides the hole 13 and pops out the slide, and makes joint 7 butt valve gap 3 deviate from the face of second cliff 32, draws dismounting rod 1 with the help of the instrument or with the hand this moment again, can follow the pipeline with the valve and dismantle. In this embodiment, the first abutting surface is abutted to the end surface of the slide way, if the outer diameter of the second through hole 321 is increased or set to be a stepped hole, the first abutting surface can also be arranged in the slide way, and meanwhile, the hole shoulder is arranged on the inner hole wall of the second through hole 321 away from the first abutting surface and abutted to the elastic member 6, and after the clamping member 7 is clamped in the first clamping groove 14, the clamping member can extend into the slide way and abut to the first abutting surface, so that the disassembling and telescopic functions of the disassembling rod 1 can also be realized.

The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
