Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an on / off valve for water pipes. Background Technology

[0002] Current water pipe valves use multi-stage transmission components, resulting in a large number of parts and complex inter-part coordination, which leads to a complex valve structure and reduced reliability. Utility Model Content

[0003] The purpose of this utility model is to provide an on / off valve and a faucet for water pipes, which reduces the number of parts used, has a simple structure, and is more reliable.

[0004] To achieve the above objectives, the solution of this utility model is as follows:

[0005] A shut-off valve for water pipes, capable of being installed inside the pipe, includes a housing, a sealing plug, a valve core, an annular sleeve, and a handle. The housing has a cavity with an inlet and an outlet. The inlet is connected to an inlet channel, and the outlet is connected to an outlet channel. A strip-shaped hole is circumferentially arranged on the sidewall of the cavity. The sealing plug, valve core, and annular sleeve are all located within the cavity. The sealing plug is located at the inlet and has an inlet hole that communicates with the inlet channel. The valve core is coaxially positioned on the side of the sealing plug opposite to the inlet and has an outlet hole that communicates with the outlet channel. The valve core can rotate within the cavity around its own axis to drive the outlet... The water inlet rotates around the valve core axis, with the inlet located on the rotation path of the outlet. By rotating the valve core, the outlet and inlet can be connected or disconnected. The annular sleeve is coaxially fitted around the outer circumference of the valve core, and the two are connected to each other. The annular sleeve can rotate to drive the valve core to rotate around its own axis, and part of the outer wall of the annular sleeve is exposed through the slotted hole. The handle can be connected to the annular sleeve after passing through the slotted hole. Under the action of external force, the handle can swing from one end of the slotted hole to the other end to drive the annular sleeve to rotate, which in turn drives the valve core to rotate around its own axis, so that the inlet and outlet can be connected or disconnected.

[0006] Furthermore, the handle is detachably attached to the ring sleeve after passing through the slot.

[0007] Preferably, the outer side wall of the annular sleeve exposed through the strip hole is provided with a threaded hole, and one end of the handle is provided with a thread. The threaded end of the handle passes through the strip hole and is screwed into the threaded hole, so that the handle is detachably connected to the annular sleeve.

[0008] Furthermore, the outer shell includes a cover and a housing. The housing has a cavity with one end open. The cover is screwed to the opening of the cavity so that the two together form the cavity. The water outlet and water outlet channel of the cavity are located on the cover. The water inlet and water inlet channel of the cavity are located on the housing, and the strip-shaped hole is circumferentially arranged on the side wall of the housing.

[0009] Furthermore, the cavity also has a limiting plug, which is located on the side of the valve core away from the sealing plug. One side of the limiting plug abuts against the edge of the water outlet end of the cavity, and the other side abuts against the valve core, so as to abut against the valve core and the sealing plug to seal tightly and restrict the movement of the valve core and the sealing plug. The limiting plug also has a through hole, which is connected to the water outlet hole and the water outlet channel.

[0010] Furthermore, a second snap-fit ​​protrusion is provided on the outer side wall of the valve core, and a corresponding second snap-fit ​​groove is provided on the inner side wall of the annular sleeve. When the annular sleeve is fitted onto the outer circumference of the valve core, the second snap-fit ​​protrusion is engaged into the second snap-fit ​​groove, so that the annular sleeve and the valve core are engaged with each other to form a whole.

[0011] Furthermore, a third snap-fit ​​protrusion is provided on the outer side wall of the sealing plug, and a third snap-fit ​​groove is provided on the side wall at the water inlet end of the cavity. The third snap-fit ​​protrusion is snapped into the third snap-fit ​​groove so that the sealing plug and the side wall of the cavity are snapped together and fixed.

[0012] Furthermore, a threaded section is provided on the outer wall of the water outlet channel, which is used to connect with the water pipe.

[0013] This utility model also provides a water tap that uses the on / off valve described above. The on / off valve is installed inside the water tap to control the water flow on and off.

[0014] Furthermore, the faucet is a dual-outlet faucet, comprising a faucet body connected to a water source, and also connected to a raw water outlet pipe and a purified water outlet pipe. The raw water outlet pipe is used to directly release the water supplied by the water source, and the purified water outlet pipe is equipped with a filter device to release the water supplied by the water source after filtration. The on / off valve is installed in the purified water outlet pipe, and the pipe wall of the purified water outlet pipe has a second strip hole corresponding to the strip hole of the on / off valve. The handle passes through the second strip hole and the strip hole in sequence and is connected to an annular sleeve so that the release of filtered water can be switched by rotating the handle.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0016] The on / off valve of this utility model rotates the handle, thereby rotating the annular sleeve, which in turn rotates the valve core. This allows the water outlet on the valve core to connect or disconnect with the water inlet on the sealing plug, thus connecting or disconnecting the water outlet channel and the water inlet channel to control the flow of water in the pipe. Compared with existing valves, it has fewer parts, reduces manufacturing costs, and has a simpler structure and better reliability. Attached Figure Description

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 4As shown, this embodiment provides an on / off valve 9 for water pipes, which includes a housing 1, a sealing plug 2, a valve core 3, an annular sleeve 4, and a handle 42. The housing 1 has a cavity 10 with an inlet end 101 and an outlet end 102. The inlet end 101 is connected to an inlet channel 11, and the outlet end 102 is connected to an outlet channel 12. A strip-shaped hole 13 is circumferentially provided on the side wall of the cavity 10. The sealing plug 2, valve core 3, and annular sleeve 4 are all located within the cavity 10. The sealing plug 2 is located at the inlet end 101 and has an inlet hole 20 connected to the inlet channel 11. The valve core 3 is coaxially disposed on the side of the sealing plug 2 opposite to the inlet end 101 and has an outlet hole 30 connected to the outlet channel 12. The valve core 3 can be connected to the handle 42 within the cavity 10. The valve core 3 rotates around its own axis to drive the outlet hole 30 to rotate around the axis of the valve core 3. The inlet hole 20 is located on the rotation path of the outlet hole 30. By rotating the valve core 3, the outlet hole 30 and the inlet hole 20 can be connected or disconnected. The annular sleeve 4 is coaxially sleeved on the outer circumference of the valve core 3 and the two are connected to each other. The annular sleeve 4 can rotate to drive the valve core 3 to rotate around its own axis, and part of the outer wall of the annular sleeve 4 is exposed through the strip hole 13. The handle 42 can be connected to the annular sleeve 4 after passing through the strip hole 13. Under the action of external force, the handle 42 can swing from one end of the strip hole 13 to the other end to drive the annular sleeve 4 to rotate, thereby driving the valve core 3 to rotate around its own axis, so that the inlet hole 20 and the outlet hole 30 can be connected or disconnected.

[0027] The water pipe on / off valve 9 of this utility model rotates the handle 42, thereby rotating the annular sleeve 4, which in turn rotates the valve core 3, so that the water outlet 30 on the valve core 3 and the water inlet 20 on the sealing plug 2 are connected or disconnected, and the water outlet channel 12 and the water inlet channel 11 are connected or disconnected, so as to control the flow of water in the water pipe. Compared with existing valves, it has fewer parts, reduces manufacturing costs, and has a simpler structure and better reliability.

[0028] Furthermore, the handle 42 is detachably connected to the annular sleeve 4 after passing through the strip hole 13.

[0029] Preferably, the outer side wall of the annular sleeve 4 exposed through the strip hole 13 is provided with a threaded hole 40, and one end of the handle 42 is provided with a thread. The threaded end of the handle 42 passes through the strip hole 13 and is screwed into the threaded hole 40, so that the handle 42 is detachably connected to the annular sleeve 4. The length of the strip hole 13 limits the rotation angle of the handle 42 to 0°-90°. Furthermore, the engagement of the threaded hole 40 and the thread facilitates the disassembly and assembly of the handle 42 and allows for the replacement of handles 42 with different shapes.

[0030] Furthermore, the cavity 10 also has a limiting plug 5, which is located on the side of the valve core 3 away from the sealing plug 2. One side of the limiting plug 5 abuts against the edge of the water outlet 102 of the cavity 10, and the other side abuts against the valve core 3, so as to seal the valve core 3 and the sealing plug 2 tightly to prevent water leakage and restrict the movement of the valve core 3 and the sealing plug 2. The limiting plug 5 has a through hole 50, which is connected to the water outlet 30 and the water outlet channel 12. Specifically, the limiting plug 5 is coaxially located on the side of the valve core 3 away from the sealing plug 2. Specifically, the water outlet 30 of the valve core 3 is located within the range of the through hole 50, so that the through hole 50 and the water outlet 30 are connected. When the water outlet 30 and the water inlet 20 are connected, the water flow can pass through the water inlet 20, the water outlet 30, and the through hole 50 in sequence and then flow out from the water outlet channel 12.

[0031] Specifically, a first engaging protrusion 51 is provided on the outer side wall of the limiting plug 5, and a corresponding first engaging groove 14 is provided on the side wall of the water outlet 102 of the cavity 10. The first engaging protrusion 51 is engaged into the first engaging groove 14, thereby enabling the limiting plug 5 to be engaged in the cavity 10 and preventing the limiting plug 5 from rotating.

[0032] Furthermore, a second snap-fit ​​protrusion 31 is provided on the outer side wall of the valve core 3, and a corresponding second snap-fit ​​groove 41 is provided on the inner side wall of the annular sleeve 4. When the annular sleeve 4 is fitted around the outer periphery of the valve core 3, the second snap-fit ​​protrusion 31 is engaged into the second snap-fit ​​groove 41, so that the annular sleeve 4 and the valve core 3 are engaged with each other to form a whole. When the annular sleeve 4 rotates, it can drive the valve core 3 to rotate around its own axis, thereby making the water outlet 30 on the valve core 3 and the water inlet 20 on the sealing plug 2 either connected or misaligned.

[0033] Furthermore, a third snap-fit ​​protrusion 21 is provided on the outer side wall of the sealing plug 2, and a third snap-fit ​​groove 15 is provided on the side wall at the water inlet end 101 of the cavity 10. The third snap-fit ​​protrusion 21 is snapped into the third snap-fit ​​groove 15 so that the sealing plug 2 and the side wall of the cavity 10 are snapped together and fixed to prevent the sealing plug 2 from rotating.

[0034] Specifically, the outer shell 1 includes a cover 16 and a shell 17. The shell 17 has a cavity 171 with one end open. The cover 16 is screwed to the opening of the cavity 171 so that the two together form the cavity 10. The water outlet 102 and the water outlet channel 12 of the cavity 10 are located on the cover 16. The water inlet 101 and the water inlet channel 11 of the cavity 10 are provided on the shell 17. The strip hole 13 is circumferentially provided on the side wall of the shell 17. Preferably, after the shell 17 and the cover 16 are screwed together, the outer side wall of the shell 17 is located outside the outer side wall of the cover 16, so that the cover 16 is embedded in the shell 17, making the side wall of the outer shell 1 flat.

[0035] Specifically, the first snap-fit ​​groove 14 is located on the inner wall of the cover 16, and the third snap-fit ​​groove 15 is located on the inner wall of the housing 17. When installing the sealing plug 2, the annular sleeve 4, the valve core 3, and the limiting plug 5, the cover 16 needs to be unscrewed from the opening of the cavity 171 to open the cavity 10. The sealing plug 2, the annular sleeve 4, and the valve core 3 are then placed inside the cavity 171. The limiting plug 5 is then snapped onto the inner wall of the cover 16, abutting against the water outlet 102. The cover 16 is then screwed onto the opening of the cavity 171. During the screwing of the cover 16 onto the opening of the cavity 171, the limiting plug 5 gradually presses against the valve core 3 and the sealing plug 2. It is understood that when inserting the sealing plug 2, the third snap-fit ​​protrusion 21 and the third snap-fit ​​groove 15 of the sealing plug 2 need to be aligned. When inserting the valve core 3, it is necessary to... First, align the second snap-fit ​​protrusion 31 of the valve core 3 with the second snap-fit ​​groove 41 of the annular shape, and snap-fit ​​the annular sleeve 4 onto the outer circumference of the valve core 3. Then, place the valve core 3 and the annular sleeve 4 together into the cavity 171. Alternatively, the annular sleeve 4 can be placed in first, followed by the valve core 3, depending on the user's needs. No limitation is imposed here. When installing the limiting plug 5, first align the first snap-fit ​​protrusion 51 and the first snap-fit ​​groove 14 of the limiting plug 5, and snap-fit ​​the limiting plug 5 into the cover 16. Then, screw the cover 16 into the opening of the cavity 171. During the screwing process of the cover 16, the limiting plug 5 presses against the valve core 3 and seals the plug 2, thus completing the installation. Therefore, this utility model is simple to disassemble and assemble, and has low maintenance costs. It is understood that when installing the annular sleeve 4, the threaded hole 40 of the annular sleeve 4 needs to be exposed within the range of the strip hole 13.

[0036] Furthermore, a threaded section 7 is provided on the outer wall of the water outlet channel 12, which is used to connect with the water pipe.

[0037] Specifically, the sealing plug 2 preferably has two inlet holes 20, and the valve core 3 preferably has two outlet holes 30. The inlet holes 20 and outlet holes 30 have the same shape. During the rotation of the valve core 3, the inlet holes 20 and outlet holes 30 can be connected or misaligned. When the two inlet holes 20 and the two outlet holes 30 are completely overlapped and connected, the inlet channel 11 and the outlet channel 12 are connected to the maximum extent. When the two inlet holes 20 and the two outlet holes 30 are completely misaligned, the inlet channel 11 and the outlet channel 12 are completely separated. Specifically, if the handle 42 is at one end of the strip hole 13, the inlet holes 20 and the outlet holes 30 are connected. When the handle 42 is swung from one end to the other end of the strip hole 13, the water inlet hole 20 and the water outlet hole 30 change from a state of complete overlap and connection to a state of partial overlap and connection, and finally to a state of complete misalignment and disconnection. Conversely, they change from a state of complete misalignment and disconnection to a state of partial overlap and connection, and finally to a state of complete overlap and connection. This can be set according to the user's needs and is not limited here. It is understood that the number of water inlet holes 20 and water outlet holes 30 is the same, and multiple holes can also be set. The specific number is set according to the actual situation and is not limited here.

[0038] Specifically, a sealing ring 6 is provided between the water inlet 20 of the sealing plug 2 and the water inlet 101 of the cavity 10 to prevent water from flowing out of the water inlet channel 11. A sealing ring 6 is provided between the annular sleeve 4 and the strip hole 13 to prevent water from flowing out of the strip hole 13. A sealing ring 6 is provided between the sealing plug 2 and the valve core 3 to prevent water leakage when the water inlet 20 and the water outlet 30 are misaligned. A sealing ring 6 is provided between the through hole 50 of the limiting plug 5 and the water outlet 102 of the cavity 10 to prevent leakage into the water outlet channel 12. A sealing ring 6 is also provided on the outer wall of the water outlet channel 12 to seal the connection between the water outlet channel 12 and the water pipe.

[0039] like Figures 5 to 6 As shown, this utility model also provides a water tap that uses the on / off valve 9 described above. The on / off valve 9 is installed inside the water tap to control the water flow of the tap; specifically, it is installed inside the water pipe of the water tap.

[0040] Specifically, the faucet is a dual-outlet faucet 8, which includes a faucet body 80 connected to a water source, and also connected to a raw water outlet pipe 81 and a purified water outlet pipe 82. The raw water outlet pipe 81 is used to directly release the water supplied by the water source, and the purified water outlet pipe 82 is equipped with a filter device to release the water supplied by the water source after filtration. The on / off valve 9 is installed in the purified water outlet pipe 82. The pipe wall of the purified water outlet pipe 82 has a second strip hole 83 corresponding to the strip hole 13 of the on / off valve 9. The handle 42 passes through the second strip hole 83 and the strip hole 13 in sequence and is connected to the annular sleeve 4 so that the release of filtered water can be switched by rotating the handle 42.

[0041] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0042] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
