Description

TECHNICAL FIELD

[0001] The utility model belongs to the tap water structure technical field, specifically relates to tap water valve structure. BACKGROUND

[0002] The tap of general household is replaced after about 5 years due to the increase of lead precipitation, or the tap is replaced due to the quality problem of the tap, and the tap will also be replaced.

[0003] For the area with high modernization degree, each household generally has a water valve, to ensure that the water does not splash when replacing the tap, the water valve is closed before replacing the tap, and the water supply is cut off, and then the tap is replaced.

[0004] However, for the area with low modernization degree (such as rural area of a certain place), the water valve is not generally installed on the water pipe, but a total water valve is shared by multiple households. In order to take care of each household and ensure that each household can cut off the water supply, the total water valve is generally located in the public area of multiple households, such as the total water valve of two households is generally installed in the outdoor public area of two households, which leads to the following situation: if one of the households needs to replace the tap, it needs to go out and close the total water valve, which causes unnecessary movement and inconvenience; closing the total water valve also interferes with the water use of the other household, which is more inconvenient. INVENTION CONTENTS

[0005] In order to solve the above problems, the utility model provides a tap water valve structure, which can avoid manually cutting off the water supply when replacing the tap, and also avoids going out and closing the total water valve of multiple households, improving the convenience of replacing the tap.

[0006] In order to achieve the above purpose, the following technical contents are adopted in the present scheme:

[0007] The tap water valve structure comprises a one-way valve structure, an opening and closing member and a tap body; the one-way valve structure comprises:

[0008] A one-way valve housing body, one end of which is connected with the water pipe, and the other end is connected with the tap body;

[0009] A support plate installed in the cavity of the one-way valve housing body; a through hole is formed in the support plate;

[0010] A convex edge installed in the cavity of the one-way valve housing body, the axis direction of the one-way valve housing body is set along the left and right directions, and the support plate and the convex edge are respectively arranged on the left and right sides; the convex edge is provided with a through hole;

[0011] A guide rod is mounted on the support plate;

[0012] A water baffle is sleeved on the guide rod and can move along the axis of the guide rod relative to the guide rod; the water baffle is located between the support plate and the convex edge;

[0013] A spring is located between the support plate and the convex edge and is in a compressed state, with the left end abutting against the right end surface of the support plate and the right end abutting against the left end surface of the water baffle; under the elastic restoring force of the spring, the right end surface of the water baffle can abut against the left end surface of the convex edge and cut off the water path in the cavity of the one-way valve housing body;

[0014] A start-stop piece is located on the right side of the water baffle, and the start-stop piece can be abutted and moved left by the faucet body mounted on the right end of the one-way valve housing body, and the left movement of the start-stop piece can make the water baffle no longer cut off the water path.

[0015] Further, the start-stop piece is in the shape of a circular tube, the start-stop piece is located in the through hole of the convex edge, the length of the start-stop piece in the left-right direction is longer than the length of the convex edge in the left-right direction; the outer wall of the start-stop piece does not contact the through hole of the convex edge, and a plurality of strip-shaped holes are formed in the circumferential side wall of the start-stop piece.

[0016] The start-stop piece in the shape of a circular tube is easy to process, and the contact surface between the start-stop piece in the shape of a circular tube and the end part of the faucet body in the shape of a circular tube is flat, water turbulence is not easy to occur, and the flow rate can be guaranteed.

[0017] Further, a through hole is formed in the middle part of the water baffle, the water baffle is sleeved on the guide rod by means of the through hole, a rubber ring is embedded in the through hole of the water baffle, the outer wall of the rubber ring abuts against the inner wall of the through hole, and the inner wall of the rubber ring abuts against the outer wall of the guide rod.

[0018] When the right end of the water baffle abuts against the left end surface of the convex edge, the water baffle can completely cut off the water path, and if the rubber ring is not provided, a small amount of water may flow out of the right end of the one-way valve housing body after the faucet body is disassembled, which affects the feeling during use.

[0019] Further, the spring is sleeved on the guide rod.

[0020] The spring is not easy to displace the one-way valve housing body and always maintains a stable elastic restoring force on the water baffle, so that the water baffle can timely cut off the water path under the elastic restoring force of the spring after the faucet body is disassembled.

[0021] Further, the guide rod is threadedly connected to the support plate.

[0022] The length of the guide rod at the right end of the support plate can be adjusted by screwing the guide rod, so that the right end of the guide rod has sufficient length, thereby ensuring that the water baffle will not be separated from the right end of the guide rod before the right end surface of the water baffle abuts against the left end surface of the convex edge.

[0023] The beneficial effects achieved by the technical scheme are as follows:

[0024] When the faucet body is disassembled, the water baffle is automatically moved and the water path is cut off by the elastic restoring force of the spring inside the one-way valve structure on the water pipe, without manually closing the house valve or the total water valve, without affecting other household water use, without the need to go out to close the valve, and convenient to use. When the faucet body is loaded, the loaded faucet body forces the water baffle to move left and continue to compress the spring through the opening and closing member, so that the internal cavity of the one-way valve shell body is in a “always open” state, and the water path is always not cut off, and the water path is cut off or opened by the valve of the faucet body, so that the faucet body is not affected in normal use.

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] See Figure 1 , the water valve structure comprises a one-way valve structure 1, an opening and closing member 2 and a faucet body 3.

[0031] Among them, the one-way valve structure 1 comprises:

[0032] The one-way valve shell body 11 is tubular as a whole, and the inner walls of both ends are provided with internal threads; in order to be used in cooperation with the faucet body 3 and the tap water pipe 17, the threads of both ends of the one-way valve shell body 11 conform to the general standard, that is, the right end of the one-way valve shell body 11 is a quarter internal thread. The left end of the one-way valve shell body 11 has an inner diameter of 20 mm and an outer diameter of 25 mm; the faucet body 3 is connected to the quarter internal thread at the right end. The use of wrapped raw rubber tape ensures the sealing of the threads at both ends of the one-way valve shell body 11.

[0033] The support plate 12 is integrally arranged on the inner wall of the cavity of the one-way valve shell body 11, and the surface of the support plate 12 is provided with a through hole. Due to the existence of the through hole, the support plate 12 does not hinder the water flow of the tap water pipe 17 through the internal cavity of the one-way valve structure 1 to the faucet body 3.

[0034] The convex edge 13 is integrally arranged on the inner wall of the cavity of the one-way valve shell body 11; the axis direction of the one-way valve shell body 11 is along the left-right direction, and the support plate 12 and the convex edge 13 are arranged left and right, respectively.

[0035] The spring 14 is located between the support plate 12 and the convex edge 13, and the spring 14 is always in a compressed state. The center line of the spring 14 is parallel to the center line of the one-way valve shell body 11.

[0036] The guide rod 15 is fixedly connected to the support plate 12, and the axis of the guide rod 15 is parallel to the center line of the one-way valve shell body 11. The right end of the guide rod 15 extends to the right side of the support plate 12. In this embodiment, the connection between the guide rod 15 and the support plate 12 is a threaded connection. The aforementioned spring 14 is sleeved on the guide rod 15.

[0037] The water baffle 16 is sleeved on the guide rod 15, and a through hole is formed in the middle of the water baffle 16 for sleeving the water baffle 16 on the guide rod 15. The water baffle 16 is movably clamped on the guide rod 15, and the water baffle 16 can move along the axis of the guide rod 15 relative to the guide rod 15. The inner wall of the through hole and the outer wall of the guide rod 15 are sealingly arranged. In the embodiment, a rubber ring 18 is embedded in the through hole, the outer wall of the rubber ring 18 abuts against the inner wall of the through hole, and the inner wall of the rubber ring 18 abuts against the outer wall of the guide rod 15, so that the sealing between the through hole and the outer wall of the guide rod 15 is realized by relying on the rubber ring 18, and the sealing between the guide rod 15 and the water baffle 16 is also maintained by relying on the rubber ring 18 during the movement of the water baffle 16. The left end of the spring 14 abuts against the right end surface of the support plate 12, and the right end abuts against the left end surface of the water baffle 16; under the compression force of the spring 14, the water baffle 16 moves to the right, and when the left end surface of the water baffle 16 abuts against the left end surface of the convex edge 13, the water baffle 16 interrupts the water path, and the one-way valve housing body 11 is in the “closed” state at this time; when the right end surface of the water baffle 16 does not abut against the left end surface of the convex edge 13, the water baffle 16 no longer interrupts the water path, and the one-way valve housing body 11 is in the “open” state at this time, at this time, the water in the internal cavity of the one-way valve housing body 11 will flow through the water baffle 16 from the gap around the water baffle 16, then flow through the convex edge 13 from the through hole in the middle of the convex edge 13, and finally flow out of the internal cavity of the one-way valve housing body 11.

[0038] The opening and closing piece 2 is located to the right of the water baffle 16, and in the embodiment, the shape of the opening and closing piece 2 is a circular tube, and the center line of the opening and closing piece 2 is parallel to the center line of the one-way valve housing body 11. The convex edge 13 is sleeved on the opening and closing piece 2 by means of the through hole, and the outer wall of the opening and closing piece 2 does not contact the inner wall of the convex edge 13, so as to ensure that water can flow to the faucet body 3 through the opening and closing piece 2, and the opening and closing piece 2 can move in the left-right direction without being limited by the convex edge 13. After the one-way valve housing body 11 is installed with the faucet body 3 at the right end, the left end of the opening and closing piece 2 abuts against the right end surface of the water baffle 16, so that due to the existence of the faucet body 3, the faucet body 3 forces the spring 14 to further compress based on the opening and closing piece 2, so that the right end surface of the water baffle 16 no longer abuts against the left end surface of the convex edge 13. When the right end of the one-way valve housing body 11 is not installed with the faucet body 3, since the faucet body 3 does not force the opening and closing piece 2 to move to the left, the spring force of the spring 14 forces the right end surface of the water baffle 16 to abut against the left end surface of the convex edge 13.

[0039] See Figure 2The circumferential surface of the opening and closing member 2 is provided with a plurality of strip-shaped holes 19. When the right end surface of the water baffle 16 is no longer in contact with the left end surface of the convex edge 13, the strip-shaped holes 19 are no longer in the through hole of the convex edge 13. Water flows around the water baffle 16 and then smoothly enters the internal cavity of the opening and closing member 2 through the strip-shaped holes 19, and finally flows to the faucet body 3. The strip-shaped holes 19 increase the width of the water flow path, thereby avoiding the water flow of the faucet body 3 being too small.

[0040] In the embodiment, the depth at which the faucet body 3 is screwed into the right end of the one-way valve housing body 11 is designed to ensure that when the faucet body 3 is completely screwed onto the right end of the one-way valve housing body 11, the faucet body 3 must first contact the opening and closing member 2, then push the water baffle 16 to the left through the opening and closing member 2, and finally make the right end surface of the water baffle 16 disengage from the left end surface of the convex edge 13, showing Figure 3 the state. Moreover, in order to ensure that the faucet body 3 can reliably push the opening and closing member 2 when being screwed in, the length of the opening and closing member 2 in the left-right direction is longer than the length of the convex edge 13 in the left-right direction. When the faucet is completely screwed into the one-way valve housing body 11, the left end thereof first contacts the opening and closing member 2 and compresses the spring 14 through the opening and closing member 2, so that the water baffle 16 disengages from the convex edge 13, thereby opening the water path.

[0041] The use process of the structure is as follows:

[0042] When the faucet body 3 is disassembled, the operator directly unscrews the faucet body 3 from the right end of the one-way valve housing body 11. As the faucet body 3 is continuously unscrewed from the right end of the one-way valve housing body 11, the spring 14 pushes the water baffle 16 to the right, and the water baffle 16 pushes the opening and closing member 2 to the right. Because the faucet body 3 is slowly unscrewed, the opening and closing member 2 will not be quickly ejected from the cavity of the one-way valve housing body 11 by the spring 4. Finally, the spring 14 abuts the right end surface of the water baffle 16 against the left end surface of the convex edge 13, thereby cutting off the water path in the internal cavity of the one-way valve housing body 11. After the faucet body 3 is unscrewed from the right end of the one-way valve housing body 11, a new faucet body 3 can be replaced. At this time, even if the faucet body 3 has been disassembled, the internal cavity of the one-way valve housing body 11 is cut off, so no water will be sprayed.

[0043] When loading a new faucet body 3, the operator directly screws the new faucet body 3 on the right end of the one-way valve shell body 11, as the new faucet body 3 is continuously screwed into the one-way valve shell body 11 to the left, the left end of the new faucet body 3 is in contact with the right end surface of the opening and closing member 2, the new faucet body 3 continues to screw into the one-way valve shell body 11, so that the new faucet body 3 forces the opening and closing member 2 to move left, and finally the right end surface of the baffle 16 is separated from the left end surface of the convex edge 13, the baffle 16 no longer interrupts the waterway, the water pipe 17, the one-way valve shell body 11 and the new faucet body 3 are connected, and through the valve of the new faucet body 3, the interruption and opening of the waterway in daily life are realized. The whole process of replacing the faucet body 3 does not need to close other water valves, avoiding the inconvenience caused by going out, affecting other users to use water. Note that when unscrewing the faucet body from the one-way valve shell body 11, it needs to be slowly unscrewed to avoid the safety hazard caused by the rapid release of the opening and closing member 2 due to the spring 14 force. A limiting structure can be additionally provided in the one-way valve shell body 1 to limit the maximum displacement of the opening and closing member 2, so as to avoid the above problems. No further design is made on the above structure, which can be used as a subsequent improvement point.

[0044] With the above ideal embodiment according to the present application as the inspiration, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
