DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are preferred embodiments of the present application, and should not be regarded as excluding other embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] Referring to Figure 1 The water stop piece 100 for the water valve provided by the embodiment of the present application includes a column body 120 and an end cover 110, and the column body 120 and the end cover 110 are coaxially arranged. In the embodiment, the column body 120 and the end cover 110 are integrally formed, and in other embodiments, the column body 120 and the end cover 110 can be two independent parts, which are fixedly connected through screw connection, plug-in connection or bonding. Figure 1 As shown in the figure, the inside of the column body 120 is hollow to form an internal passage, the internal passage penetrates through one end of the column body 120 away from the end cover 110, the outer periphery of the column body 120 is provided with a water passing hole communicating with the internal passage, and the water passing hole and the internal passage constitute the water passing channel 121. In other embodiments, the water passing channel 121 can also be formed by arranging a groove extending from one end to the other end of the column body 120 on the outside of the column body 120.

[0023] The water stop piece 100 for the water valve provided by the embodiment of the present application is placed in the water inlet pipeline 200 of the water valve in actual use. The water valve referred to in the present application refers to an angle valve, a faucet, a mixed water valve and other bathroom products for connecting with an external water pipe 700 to control water flow output. The basic structures of such products are similar, and all include a water inlet pipeline, a water outlet pipeline and a valve core for controlling water output or not. As Figure 2As shown, the diameter of the end cap 110 is larger than the diameter of the cylinder 120, and is larger than the inner diameter of the water inlet pipe 200, and the diameter of the cylinder 120 is smaller than the inner diameter of the water inlet pipe 200. It should be noted that the diameter of the components in the present application means the distance between the two most distant points in the radial direction of the component, and is not limited to the circular shape of the component. In actual use, the length of the cylinder 120 is selected according to the structure of the water valve, so that the length of the cylinder 120 is greater than the distance from the limiting structure 600 in the water valve to the inlet of the water inlet pipe 200. The limiting structure 600 in the water valve refers to a structure that can limit the axial movement of the water stop 100, such as the valve core 500, or a limiting structure 600 formed by an inward protrusion provided on the valve seat section 400, the water inlet pipe 200 section, or the connection between the water inlet pipe 200 and the valve seat section 400, or a limiting structure 600 formed by an inward protrusion provided in the water inlet pipe 200.

[0024] Preferably, a plurality of anti-loose ribs 122 are further provided on the outer periphery of the cylinder 120. The cylinder 120 with the anti-loose ribs 122 has a diameter slightly smaller than the inner diameter of the water inlet pipe 200. By providing the anti-loose ribs 122, the diameter of the cylinder 120 is only slightly smaller than the inner diameter of the water inlet pipe 200, which on the one hand ensures that the cylinder 120 can move axially in the water inlet pipe 200 flexibly, and on the other hand the anti-loose ribs 122 are close to the inner wall of the water inlet pipe 200, which can limit the cylinder 120 in the radial direction, reducing the large shaking of the water stop 100 during normal use.

[0025] When the water inlet pipe 200 is not broken, the length of the cylinder 120 is greater than the distance from the limiting structure 600 to the inlet of the water inlet pipe 200, so that the end cap 110 of the water stop 100 is located outside the water inlet pipe 200 and has a certain distance from the inlet of the water inlet pipe 200. At this time, the end cap 110 has a gap with the inner wall of the external water pipe 700, and the end cap 110 also has a gap with the inlet end face of the water inlet pipe 200, which can be used for water flow. As shown in FIG. 3, the water flow in the external water pipe 700 can pass through the gap between the end cap 110 and the inner wall of the external water pipe 700, the gap between the end cap 110 and the inlet end face of the water inlet pipe 200, and the water passage 121 on the cylinder 120, to reach the valve core 500 position, and when the valve core 500 is opened, the water flow flows out through the water outlet pipe 300. When the water inlet pipe 200 is broken, the cylinder 120 loses the limitation of the limiting structure 600, and the water stop 100 moves under the action of the water flow to make the end cap 110 fit the water inlet pipe 200. At this time, the end cap 110 blocks the inlet of the water inlet pipe 200 to prevent the water flow in the external water pipe 700 from flowing out of the water inlet pipe 200. At this time, there is no water flow or only a small amount of water flow leaking at the broken water inlet pipe 200, and the floor drain has enough time to drain the leaked water flow, without flooding the floor.

[0026] In some preferred embodiments, a sealing ring 130 is arranged at the connection between the end cover 110 and the column 120, and the diameter of the sealing ring 130 is greater than the inner diameter of the water inlet pipe 200. By arranging the sealing ring 130, the sealing between the end cover 110 and the inlet of the water inlet pipe 200 can be stronger when the water inlet pipe 200 is broken. Further, the side of the end cover 110 away from the column 120 is flat or concave towards the column 120, so that the water flow has a greater force on the water stop 100, and thus the water stop 100 can be more tightly attached to the inlet of the water inlet pipe 200 under the action of the water flow when the water inlet pipe 200 is broken. In some other embodiments, the sealing ring 130 can not be arranged, and the sealing effect is poor, or a small amount of water seepage or leakage is allowed between the end cover 110 and the inlet of the water inlet pipe 200. The small amount of water seepage or leakage can flow out from the floor drain provided on the floor in time, and will not cause great loss to the user's home.

[0027] The water stop 100 for a water valve provided in the embodiments of the present application has a simple structure, and can be adapted to most models of water valves on the market by selecting a water stop 100 with a proper size, without changing the structure of the water valve, and has strong universality.

[0028] Referring to Figures 1-3 The utility model embodiment still provides a water valve with water stop 100, including body and valve core 500, the body includes water inlet pipe 200, water outlet pipe 300 and valve seat section 400, valve seat section 400 connects water inlet pipe 200 with water outlet pipe 300, valve core 500 is installed in valve seat section 400, still include water stop 100, water stop 100 includes coaxial arrangement column 120 and end cover 110, the diameter of end cover 110 is greater than the inner diameter of water inlet pipe 200, the diameter of the maximum place of column 120 is less than the inner diameter of water inlet pipe 200, and column 120 is inserted into water inlet pipe 200, limit structure 600 is arranged in water inlet pipe 200 or valve seat section 400, limit structure 600 limits the travel range of water stop 100 along the axial direction, and the length of column 120 is greater than the distance from limit structure 600 to the inlet of water inlet pipe 200.

[0029] Specifically, the water valve referred to in the present application refers to a corner valve, a faucet, a water mixing valve and the like for connecting with an external water pipe 700 to control water flow output. The water valve comprises a body and a valve core 500, the body comprising a water inlet pipe 200, a water outlet pipe 300 and a valve seat section 400, the valve seat section 400 connecting the water inlet pipe 200 and the water outlet pipe 300, and the valve core 500 being installed on the valve seat section 400. Among them, the water inlet pipe 200 is used for connecting with the external water pipe 700, the valve core 500 can change the communication relationship between the water outlet pipe 300 and the water inlet pipe 200 to realize the on-off control of water flow, and the water outlet pipe 300 is used for water flow output. In some preferred embodiments, the water inlet pipe 200 is provided with an external thread on the outer side close to the inlet for connecting with the external water pipe 700. The water valve of the embodiment of the present application is inserted into the external water pipe 700 to connect with the external water pipe 700 through the water inlet pipe 200.

[0030] As shown in Figure 1 The water stop 100 provided by the embodiment of the present application comprises a column body 120 and an end cover 110, and the column body 120 and the end cover 110 are coaxially arranged. In the embodiment, the column body 120 and the end cover 110 are integrally formed, and in other embodiments, the column body 120 and the end cover 110 can be two independent parts which are fixedly connected through screw connection, plug-in connection or bonding and the like. The column body 120 is formed with a water passing channel 121 which is communicated from one end of the column body 120 to the other end of the column body 120. In the embodiment of the present application, as shown in Figure 1 The inside of the column body 120 is hollow to form an internal channel, the internal channel penetrates through the end of the column body 120 which is away from the end cover 110, and the outer periphery of the column body 120 is provided with a water passing hole which is communicated with the internal channel, and the water passing hole and the internal channel constitute the water passing channel 121. In other embodiments, the water passing channel 121 can also be formed by arranging a groove on the outer side of the column body 120 which extends from one end of the column body 120 to the other end.

[0031] As shown in Figure 4As shown, the diameter of the end cap 110 is larger than the diameter of the column 120 and larger than the inner diameter of the water inlet pipe 200. The diameter of the column 120 is smaller than the inner diameter of the water inlet pipe 200. It should be noted that the diameter of the component mentioned in this application refers to the distance between the two points of the component that are furthest apart in the radial direction, and does not limit the component to be circular. Preferably, a plurality of anti-displacement ribs 122 are also protruding on the outer periphery of the column 120. The diameter of the column 120 with anti-displacement ribs 122 is slightly smaller than the inner diameter of the water inlet pipe 200. By setting the ribs, the diameter of the column 120 is only slightly smaller than the inner diameter of the water inlet pipe 200. On the one hand, this ensures that the column 120 can move flexibly along the axial direction within the water inlet pipe 200. On the other hand, the ribs are close to the inner wall of the water inlet pipe 200 and can limit the column 120 in the radial direction, reducing the large shaking of the water stop 100 during normal use.

[0032] like Figure 4 As shown, the column 120 is inserted into the water inlet pipe 200; a limiting structure 600 is provided inside the water inlet pipe 200 or the valve seat section 400, the limiting structure 600 restricts the axial travel range of the water-stopping member 100, and the length of the column 120 is greater than the distance from the limiting structure 600 to the inlet of the water inlet pipe 200. In some embodiments, the valve core 500 is used as the limiting structure 600, and the length of the column 120 is greater than the distance from the valve core 500 to the inlet of the water inlet pipe 200. In other embodiments, an inwardly protruding limiting structure 600 is provided at the connection between the valve seat section 400, the water inlet pipe section 200, or the connection between the water inlet pipe 200 and the valve seat section 400, and the length of the column 120 is greater than the distance from the limiting protrusion to the inlet of the water inlet pipe 200. Furthermore, when an inwardly protruding limiting structure 600 is provided at the valve seat section 400, the inlet pipe section 200, or the connection between the inlet pipe 200 and the valve seat section 400, the limiting structure 600 is an annular step, and the diameter of the end of the column 120 away from the end cap 110 is larger than the inner diameter of the limiting structure 600, so that it can limit the water-stopping element 100 at any angle. In other embodiments, a bend can also be provided at the valve seat section 400, the inlet pipe section 200, or the connection between the inlet pipe 200 and the valve seat section 400 to form the limiting structure 600, and the length of the column 120 is greater than the distance from the outer side of the bend to the inlet of the inlet pipe 200. Preferably, the limiting structure 600 is located outside the external threaded area on the outer side of the inlet pipe 200 for connection with the external water pipe 700.

[0033] In actual use, when the water inlet pipe 200 is not broken, the end cover 110 of the water stop piece 100 is located outside the water inlet pipe 200 and has a certain distance from the inlet of the water inlet pipe 200, because the length of the column 120 is greater than the distance from the limiting structure 600 to the inlet of the water inlet pipe 200. At this time, the end cover 110 has a gap with the inner wall of the external water pipe 700 and the end cover 110 has a gap with the inlet end surface of the water inlet pipe 200, which can allow water flow to pass. As shown in FIG. 4, the water flow in the external water pipe 700 can pass through the gap between the end cover 110 and the inner wall of the external water pipe 700, the gap between the end cover 110 and the inlet end surface of the water inlet pipe 200, and the water passing channel 121 on the column 120, to reach the valve core 500 position, and flow out through the water outlet pipe 300 when the valve core 500 is opened. As shown in FIG. 5, when the water inlet pipe 200 is broken, the column 120 loses the limitation of the limiting structure 600, and the water stop piece 100 moves under the action of the water flow to make the end cover 110 fit the water inlet pipe 200. At this time, the end cover 110 blocks the inlet of the water inlet pipe 200 to prevent the water flow in the external water pipe 700 from flowing out of the water inlet pipe 200. At this time, there is no water flow or only a small amount of water flow leaking at the broken water inlet pipe 200, and the floor drain on the floor can have enough time to drain the leaked water flow without flooding the floor. Figure 5

[0034] In some preferred embodiments, a sealing ring 130 is arranged at the connection between the end cover 110 and the column 120, and the diameter of the sealing ring 130 is greater than the inner diameter of the water inlet pipe 200. By arranging the sealing ring 130, the sealing between the end cover 110 and the inlet of the water inlet pipe 200 can be stronger when the water inlet pipe 200 is broken. Further, the side of the end cover 110 away from the column 120 is flat or concave towards the column 120, so that the water flow has a greater force on the water stop piece 100, and thus the water stop piece 100 can be more closely fitted to the inlet of the water inlet pipe 200 under the action of the water flow when the water inlet pipe 200 is broken. In other embodiments, the sealing ring 130 can not be arranged, and the sealing effect is poor, or a small amount of water can seep or leak between the end cover 110 and the inlet of the water inlet pipe 200. The small amount of water can be drained from the floor drain on the floor in time, and also will not cause great loss to the user's home.

[0035] The water stop piece 100 for a water valve provided in the embodiments of the present application has a simple structure, and can be adapted to most models of water valves on the market by selecting a water stop piece 100 with a suitable size, without changing the structure of the water valve, and has strong universality.
