Angle valve capable of being fractured to stop water

Abstract

The utility model provides an angle valve capable of being fractured to stop water, and belongs to the technical field of angle valves. The angle valve solves the technical problem that an existing angle valve is poor in fracture water stopping sensitivity. An ejector rod and a water stop piece are arranged in a water inlet pipe in the angle valve capable of being fractured to stop water, a water stop check ring is fixed to the inner wall of the water inlet pipe, a connecting rod is fixed to the inner end of the water stop piece and penetrates through the water stop check ring to abut against the ejector rod, a positioning piece is fixed to a pipe opening of the water inlet pipe, and a spring is arranged between the water stop piece and the positioning piece. The inner side face of the water stop piece can abut against the water stop check ring in a sealed mode. When the connecting rod abuts against the ejector rod, a gap for water to pass through is formed between the water stop piece and the water stop check ring, and a gap for water to pass through is formed between the outer side face of the water stop piece and the inner pipe wall of the water inlet pipe. Due to the fact that the contact face between the ejector rod and the connecting rod is narrow, the ejector rod and the connecting rod can be staggered more easily when the valve body is broken, sealing and water stopping are achieved, and sensitivity is high.

Description

Technical Field

[0001] The utility model belongs to the technical field of angle valves, in particular to an angle valve capable of breaking and stopping water. Background Art

[0002] In people's daily life, angle valves are widely used as important water connection pipe parts between water outlet pipes and faucets. However, with the extensive use of angle valves, although the styles and shapes are becoming more and more diverse, many manufacturers can only make the weight of angle valves lighter and thinner in order to control costs and increase profits. This will cause the valve body of the angle valve, especially the inlet end and the valve body connection, to often break due to excessive force and cause water leakage, which will bring great safety hazards in use. It is often heard that a certain angle valve has caused great losses to users due to the breakage and leakage of the valve body during use.

[0003] The utility model patent with application number 202021117742.X discloses a safety angle valve, including a valve body, an inlet end and an outlet end. It mainly comprises a water stop part and a water stop inner shoulder added in the inlet end, the upper end of the water stop part is connected with the outlet end, the lower end is provided with a water stop support, and a plurality of water inlet holes are provided on the water stop support; therefore, the valve body at the inlet end does not break, and the inlet end, the plurality of water inlet holes and the outlet end are directly connected, that is, the angle valve is used normally for water flow; once the valve body at the inlet end breaks and leaks due to excessive force, the broken inlet end valve body will move outward under the push of the inlet water pressure, and drive the water stop inner shoulder in the valve body to seal and contact the water stop support. At this time, the connection between the inlet end and the plurality of water inlet holes can be quickly closed to reduce the water flow, thereby avoiding losses to users.

[0004] However, after the valve body of the above-mentioned safety angle valve breaks and leaks, if the crack in the valve body is not particularly large, the water stop may not be able to enter the interior of the valve body and make the water stop support and the water stop inner shoulder contact to achieve sealing, and the sensitivity is not high. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an angle valve with higher sensitivity and capable of breaking and stopping water.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] 14. The invention relates to an angle valve capable of breaking and stopping water, comprising a valve body with a control chamber, wherein the valve body is provided with a water inlet pipe and a water outlet pipe connected with the control chamber, and the characteristic is that a push rod and a water stop member are arranged in the water inlet pipe, a water stop retaining ring is fixed on the inner wall of the water inlet pipe, a connecting rod is fixed on the inner end of the water stop member, the connecting rod passes through the water stop retaining ring and abuts against the push rod, a positioning plate is fixed at the pipe mouth of the water inlet pipe, a plurality of first water passing holes for water flow to pass through are arranged on the positioning plate, a spring for driving the water stop member to move toward the control chamber is arranged between the water stop member and the positioning plate, and the inner side surface of the water stop member can be sealingly abutted against the water stop retaining ring; when the connecting rod abuts against the push rod, a gap for water to pass through is arranged between the water stop member and the water stop retaining ring, and a gap for water to pass through is arranged between the outer side surface of the water stop member and the inner tube wall of the water inlet pipe.

[0008] The angle valve realizes the limiting of the water stop by abutting against the connecting rod of the water stop. Water can normally enter the water inlet pipe from the first water hole of the positioning plate, then enter the inner end of the water inlet pipe through the gap between the water stop and the water stop retaining ring, and then flow out from the water outlet pipe through the control chamber. When the valve body breaks and leaks, the top rod and the connecting rod will be offset and can no longer limit the water stop. The water stop will move inward under the action of the spring and abut against the water stop retaining ring to achieve water-stopping seal. The structure is simple and the stability is high. Moreover, since the contact surface between the top rod and the connecting rod is narrow, it is easier to offset when the valve body breaks to achieve sealing and water stopping, and the sensitivity is high.

[0009] In the above-mentioned angle valve capable of breaking and stopping water, a sealing positioning member is fixedly connected in the water inlet pipe, and the sealing positioning member includes a cylindrical main body and a support seat for supporting a connecting rod, the inner end of the main body is reduced in diameter to form a water-stop ring, and the support seat includes at least two connecting plates and annular support rings, the support rings are respectively fixedly connected to the inner ends of the connecting plates, and the outer ends of the connecting plates are fixedly connected to the inner side surfaces of the water-stop rings, and the connecting rod passes through the support rings and abuts against the top rod.

[0010] The main body of the above-mentioned sealing positioning component can support the outer end of the water inlet pipe, thereby enhancing the structural strength of the outer end of the water inlet pipe, making it difficult for the angle valve to break at the outer end of the water inlet pipe; the design of the support seat can position the connecting rod, preventing the connecting rod from shaking too much under the impact of water flow and becoming dislocated from the top rod, thereby sealing the water inlet pipe, so that the connecting rod can only achieve sealing and water stopping when the angle valve is broken, further improving the stability of the angle valve when stopping water.

[0011] In the above-mentioned angle valve capable of breaking water-stop, the connecting rod includes a connecting part and an abutting part, the abutting part abuts against the top rod, the two ends of the connecting part are respectively fixedly connected to the abutting part and the water-stop member, the diameter of the abutting part is smaller than the diameter of the connecting part, the abutting part passes through a supporting ring and abuts against the top rod, the inner diameter of the supporting ring is smaller than the diameter of the connecting part, and when the water-stop member abuts against the water-stop retaining ring, the support ring is sleeved on the abutting part.

[0012] The design of the abutment with a smaller diameter can minimize the contact area between the push rod and the abutment while ensuring the water-stopping stability, thereby making it easier for the push rod and the connecting rod to be offset when the angle valve breaks, thereby improving the sensitivity of the water-stopping seal.

[0013] In the above-mentioned angle valve capable of breaking and stopping water, there is a movable gap between the abutting portion and the inner wall of the support ring.

[0014] Without affecting the normal operation of the angle valve, the movable gap can ensure that the abutting portion has a certain shaking angle, so that it can be more easily offset from the push rod after the angle valve breaks, further improving the sensitivity.

[0015] In the above-mentioned angle valve capable of breaking and water-stopping, the water-stop ring is provided with a first inclined surface, and the inner side of the water-stop member is provided with a second inclined surface matching the first inclined surface, and the first inclined surface and the second inclined surface abut to achieve sealing.

[0016] The cooperation between the first inclined surface and the second inclined surface can improve the sealing effect between the water stop ring and the water stop member.

[0017] In the above-mentioned angle valve capable of breaking and water-stopping, the water-stop ring and the water-stop member are both circular, an annular protrusion is formed on the outer peripheral surface of the water-stop member, and the inner end surface of the annular protrusion can abut against the inner end surface of the water-stop ring.

[0018] The design of the annular protrusion can increase the contact area between the water stop ring and the water stop member during sealing, further enhancing the sealing and water stopping effect.

[0019] In the above-mentioned angle valve capable of breaking and stopping water, a positioning groove is provided on the outer side surface of the water stop member, one end of the spring is installed in the positioning groove, and the other end abuts against the positioning sheet.

[0020] The design of the positioning groove can fix the spring to prevent the spring from detaching from the water stop under the impact of water flow, thereby improving the stability of water stopping when the angle valve breaks.

[0021] In the above-mentioned angle valve capable of breaking and stopping water, a convex ring protruding inward is provided at the connection between the water inlet pipe and the control chamber, a support part is fixed at one end of the push rod, a plurality of second water holes are provided on the support part, and the support part can be abutted against the side of the convex ring away from the control chamber.

[0022] The structural design of the above-mentioned convex ring already exists in the valve body, and its inner side cooperates with the control valve core to realize the opening and closing of the water outlet pipe. The angle valve rationally utilizes the existing convex ring structure so that it can play a supporting and limiting role for the support part. Furthermore, the design of the support part can make the top rod fixed more firmly and stably to avoid affecting the normal operation of the angle valve. The design of the second water hole can supply water to pass through, so that the normal flow of water is not affected when the angle valve is not broken.

[0023] Compared with the prior art, the technical effects of the utility model are:

[0024] 1. The utility model realizes the limit of the water stop by abutting the connecting rod of the top rod and the water stop. Water can normally enter the water inlet pipe from the first water hole of the positioning plate, then enter the inner end of the water inlet pipe through the gap between the water stop and the water stop retaining ring, and then flow out from the water outlet pipe through the control cavity;

[0025] 2. When the valve body of the utility model breaks and leaks, the top rod and the connecting rod will be staggered and can no longer limit the water stop. The water stop will move inward under the action of the spring and abut against the water stop ring to achieve water stop sealing. The structure is simple and the stability is high.

[0026] 3. In the utility model, since the contact surface between the push rod and the connecting rod is narrow, it is easier to stagger when the valve body breaks, thereby achieving sealing and water stopping, and the sensitivity is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] The angle valve capable of breaking and stopping water comprises a valve body 1 with a control chamber 13, a water inlet pipe 11 and a water outlet pipe 12 connected with the control chamber 13 are arranged on the valve body 1, a push rod 2 and a water stop member 3 are arranged in the water inlet pipe 11, a water stop retaining ring 411 is fixed on the inner wall of the water inlet pipe 11, a connecting rod 31 is fixed on the inner end of the water stop member 3, the connecting rod 31 passes through the water stop retaining ring 411 and abuts against the push rod 2, a positioning piece 5 is fixed at the pipe mouth of the water inlet pipe 11, and the positioning piece 5 A plurality of first water holes 51 for water flow are provided on the top, and a spring 6 for driving the water stop member 3 to move toward the control chamber 13 is provided between the water stop member 3 and the positioning plate 5, and the inner side surface of the water stop member 3 can be sealed and abutted with the water stop retaining ring 411; when the connecting rod 31 abuts against the top rod 2, a gap for water to pass is provided between the water stop member 3 and the water stop retaining ring 411, and a gap for water to pass is provided between the outer side surface of the water stop member 3 and the inner tube wall of the water inlet pipe 11. The angle valve realizes the limiting of the water stop member 3 by abutting against the connecting rod 31 of the water stop member 3 through the push rod 2. Water can normally enter the water inlet pipe 11 from the first water hole 51 of the positioning plate 5, and then enter the inner end of the water inlet pipe 11 through the gap between the water stop member 3 and the water stop retaining ring 411, and then flow out from the water outlet pipe 12 through the control chamber 13; when the valve body 1 breaks and leaks, the push rod 2 and the connecting rod 31 will be offset and can no longer continue to limit the water stop member 3. The water stop member 3 will move inward under the action of the spring 6 and abut against the water stop retaining ring 411 to achieve a water-stopping seal. The structure is simple and the stability is high. And because the contact surface between the push rod 2 and the connecting rod 31 is narrow, it is easier to offset when the valve body 1 breaks to achieve sealing and water stopping, and the sensitivity is high.

[0035] like Figure 1-5As shown, a sealing positioning member 4 is fixedly connected inside the water inlet pipe 11, and the sealing positioning member 4 includes a cylindrical main body 41 and a support seat 42 for supporting the connecting rod 31. The inner end of the main body 41 is reduced in diameter to form a water stop ring 411. The support seat 42 includes at least two connecting plates 421 and an annular support ring 422. The support ring 422 is fixedly connected to the inner end of the connecting plate 421, and the outer end of the connecting plate 421 is fixedly connected to the inner side surface of the water stop ring 411. The connecting rod 31 passes through the support ring 422 and abuts against the top rod 2. The main body 41 of the above-mentioned sealing positioning member 4 can support the outer end of the water inlet pipe 11, thereby enhancing the structural strength of the outer end of the water inlet pipe 11, making it difficult for the angle valve to break at the outer end of the water inlet pipe 11; the design of the support seat 42 can position the connecting rod 31, preventing the connecting rod 31 from shaking too much under the impact of the water flow and becoming dislocated from the top rod 2, thereby sealing the water inlet pipe 11, so that the connecting rod 31 can achieve sealing and water stopping only when the angle valve is broken, further improving the stability of the angle valve when stopping water.

[0036] Furthermore, the connecting rod 31 includes a connecting portion 311 and an abutting portion 312, the abutting portion 312 abuts against the top rod 2, the two ends of the connecting portion 311 are fixedly connected to the abutting portion 312 and the water stop member 3 respectively, the diameter of the abutting portion 312 is smaller than the diameter of the connecting portion 311, the abutting portion 312 passes through the supporting ring 422 to abut against the top rod 2, the inner diameter of the supporting ring 422 is smaller than the diameter of the connecting portion 311, and when the water stop member 3 abuts against the water stop retaining ring 411, the supporting ring 422 is sleeved on the abutting portion 312; there is a movable gap between the abutting portion 312 and the inner wall of the support ring 422. The design of the abutment portion 312 with a smaller diameter can minimize the contact area between the push rod 2 and the abutment portion 312 while ensuring the water-stopping stability, thereby making it easier for the push rod 2 and the connecting rod 31 to be offset when the angle valve breaks, thereby improving the sensitivity of the water-stop seal; without affecting the normal operation of the angle valve, the movable gap can ensure that the abutment portion 312 has a certain shaking angle, thereby making it easier to be offset from the push rod 2 after the angle valve breaks, thereby further improving the sensitivity.

[0037] like Figure 3-5 As shown, the water stop ring 411 is provided with a first inclined surface 412, and the inner side of the water stop member 3 is provided with a second inclined surface 32 that matches the first inclined surface 412, and the first inclined surface 412 and the second inclined surface 32 abut against each other to achieve sealing; the water stop ring 411 and the water stop member 3 are both circular, and an annular protrusion 33 is formed on the outer peripheral surface of the water stop member 3, and the inner end surface of the annular protrusion 33 can abut against the inner end surface of the water stop ring 411. The cooperation of the first inclined surface 412 and the second inclined surface 32 can improve the sealing effect between the water stop ring 411 and the water stop member 3; the design of the annular protrusion 33 can increase the contact area between the water stop ring 411 and the water stop member 3 when sealing, and further enhance the sealing and water stopping effect.

[0038] Furthermore, a positioning groove 34 is provided on the outer side of the water stop 3, one end of the spring 6 is installed in the positioning groove 34, and the other end is against the positioning sheet 5. The design of the positioning groove 34 can fix the spring 6, preventing the spring 6 from detaching from the water stop 3 under the impact of water flow, thereby improving the stability of water stopping when the angle valve breaks.

[0039] like Figure 3 and Figure 4 As shown, a convex ring 14 protruding inward is provided at the connection between the water inlet pipe 11 and the control chamber 13, a support portion 21 is fixed at one end of the push rod 2, and a plurality of second water holes 22 are provided on the support portion 21, and the support portion 21 can be against the side of the convex ring 14 away from the control chamber 13. The structural design of the convex ring 14 already exists in the valve body 1, and its inner side cooperates with the control valve core to realize the opening and closing of the water outlet pipe 12. The angle valve reasonably utilizes the existing convex ring 14 structure, so that it can play a supporting and limiting role for the support portion 21. Furthermore, the design of the support portion 21 can make the push rod 2 fixed more firmly and stably, avoiding affecting the normal operation of the angle valve, and the design of the second water holes 22 can supply water to pass through, so that the normal flow of water is not affected when the angle valve is not broken.

[0040] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope defined by the claims of the present invention.
