Referring to fig. 1-4, an angle valve 100 is provided. Can be used for waterway connection in water heating and bathroom, but is not limited to the waterway connection. The angle valve 100 includes an angle valve body 10 and a seal 20. Wherein the angle valve body 10 is formed with a flow channel 13. The flow channel 13 has an inlet end 11 and an outlet end 12. The inner surface of the flow channel 13 has an inner protrusion 14 extending in the circumferential direction of the flow channel 13, the inner protrusion 14 enclosing a flow hole 15. The seal 20 is movably disposed in the flow passage 13 in the direction of the central axis of the flow hole 15. The seal 20 serves to open or close the flow hole 15 by moving in the direction of the central axis of the flow channel 13. The portion of the seal 20 on the side of the inner projection 14 facing the inlet end 11 has a bearing surface 212 and a first water passage groove 211. The force-bearing surface 212 is oriented towards the inlet end 11 for bearing a medium pressure such that the medium entering the angle valve 100 from the inlet end 11 can push the seal 20 to close the flow opening 15. And the medium entering the angle valve 100 from the inlet end 11 flows toward the flow hole 15 through the first water passage groove 211.

The following embodiments of the present application will be described by taking the connection of the angle valve 100 to a waterway as an example, and it will be understood that when the angle valve 100 is used for waterway connection, the medium flowing into the angle valve 100 is water.

As shown in fig. 4, the angle valve body 10 is formed with a flow passage 13, and the flow passage 13 has an inlet end 11 and an outlet end 12. Wherein the angle valve body 10 may have a hollow tubular structure, and the hollow portion of the angle valve body 10 forms the flow channel 13. The flow passage 13 may be a cylindrical cavity structure, but is not limited thereto. It will be appreciated that the inlet end 11 and the outlet end 12 of the flow channel 13 are opposite ends of the angle valve body 10. When the angle valve 100 is applied to waterway connection, the inlet end 11 of the flow channel 13 is communicated with waterway, and the outlet end 12 is communicated with rear end product. The inlet end 11 of the angle valve body 10 may be formed with a coupling screw thread. The inner protrusion 14 of the inner peripheral surface of the flow passage 13 encloses the flow hole 15. The inner protrusion 14 may be a circular protrusion structure formed on the inner circumferential surface of the flow channel 13.

The seal 20 is movably provided in the flow passage 13 in the direction of the central axis of the flow hole 15 to open or close the flow hole 15 by moving in the direction of the central axis of the flow hole 15. The seal 20 in fig. 3 is in a state of opening the flow hole 15, and the seal 20 in fig. 4 is in a state of closing the flow hole 15. To move the seal 20 to close the flow hole 15 by the water pressure of the inlet end 11 of the angle valve 100, it is understood that the water pressure pushes the seal 20 to move away from the inlet end 11 to close the flow hole 15. For example, the seal 20 may close the flow hole 15 by engaging with a surface of the inner protrusion 14 on a side toward the inlet end 11, as shown in fig. 4, and in some embodiments, the inner protrusion 14 may be provided with a first inclined surface 141 on a side toward the inlet end 11, and the seal 20 may have a second inclined surface 231 engaged with the first inclined surface 141. When the sealing member 20 moves away from the inlet end 11 under the action of water pressure until the second inclined surface 231 is in contact with the first inclined surface 141, the sealing member 20 closes the flow hole 15; the sealing member 20 is moved in a direction approaching the inlet end 11 by the pushing of the connection member or the rear end connection product, and the second inclined surface 231 is separated from the first inclined surface 141, so that the communication hole 15 is opened, and the medium entering the angle valve 100 through the inlet end 11 can flow to the outlet end 12 through the communication hole.

The sealing member 20 closes the flow hole 15 by engaging with the surface of the inner protrusion 14 on the side facing the inlet end 11, and the sealing member 20 may be disposed entirely on the side of the inner protrusion 14 facing the inlet end 11 or may be disposed through the flow hole 15 in the flow channel 13 such that a part of the sealing member 20 is disposed on the side of the inner protrusion 14 facing the inlet end 11 and a part of the sealing member 20 is disposed on the side of the inner protrusion 14 facing the outlet end 12. The stress surface 212 of the sealing member 20 and the first water passing groove 211 are located at a side of the flow channel 13 facing the inlet end 11, and the stress surface 212 of the sealing member 20 is located toward the inlet end 11 to ensure that the medium flowing into the angle valve 100 from the inlet end 11 can push the angle valve 100 to move toward the flow hole 15 through the stress surface 212, and at the same time, the medium flowing into the angle valve 100 from the inlet end 11 can flow toward the flow hole 15 through the sealing member 20 and the first water passing groove 211 at a side of the inner protrusion 14 facing the inlet end 11.

To facilitate the mating of the angle valve body 10 with a connector or rear end connection product, the connector or rear end connection product can push the seal 20 in a direction toward the inlet end 11. In some embodiments, the seal 20 is disposed through the flow bore 15 within the flow channel 13.

Referring to fig. 5-7, when the seal 20 is disposed through the flow-through aperture 15 in the flow-through channel 13, the seal 20 may include a water-filtering body 21 and a water-passing plug 22 in some embodiments. Wherein the water filter 21 is embedded in the flow channel 13 at the side of the inner protrusion 14 facing the inlet end 11. The first water passage groove 211 and the stress surface 212 are formed in the water filtering body 21, and one end of the water filtering body 21, which is opposite to the inlet end 11, is provided with a connecting part 213. The water through plug 22 is embedded in a side flow channel 13 of the inner protrusion 14 towards the outlet end 12. The water passing plug 22 is connected to the connection portion 213 of the water filtering body 21. The water passing plug 22 has a second water passing groove 221, and when the flow hole 15 is opened, the second water passing groove 221 penetrates the flow hole 15, and the medium flowing out of the first water passing groove 211 flows to the outlet end 12 of the flow passage 13 through the second water passing groove 221. By making the sealing member 20 include the water filtering body 21 and the water passing plug 22, when the angle valve 100 is assembled, the water filtering body can be embedded into the inflow channel 13 from the inlet end 11, the water passing plug 22 is embedded into the inflow channel 13 from the outlet end 12, and then the water passing plug 22 is connected with the connecting part 213 of the water filtering body 21, so that the sealing member 20 can penetrate through the circulation holes 15 in the flow channel 13, and the parts positioned at two sides of the inner protrusion 14 can be respectively matched with the inner peripheral surfaces of the flow channels 13 of the corresponding sections.

It should be noted that, since the sealing member 20 is movably disposed in the flow channel 13 along the central axis direction of the flow hole 15, it is understood that the outer circumferential surfaces of the water filtering body 21 and the water passing plug 22 of the sealing member 20 are in clearance fit with the inner circumferential surface of the flow channel 13, however, the diameter size of the position where the water filtering body 21 forms the stress surface 212 needs to ensure that the stress surface 212 of the sealing member 20 can receive sufficient hydraulic force, and the diameter size of the water passing plug 22 at the end facing the outlet end 12 needs to ensure that when the connecting member is engaged with the angle valve main body 10, the end of the connecting member can abut against the end surface of the water passing plug 22 to push the sealing member 20 to move, so the specific gap values between the outer circumferential surfaces of the water filtering body 21 and the water passing plug 22 of the sealing member 20 and the inner circumferential surface of the flow channel 13 can be designed according to the actual size of the angle valve 100.

As shown in fig. 6, wherein the water filtering body 21 may be formed with a buffer chamber 214 at a side toward the inlet end 11. The buffer chamber 214 opens towards the inlet end 11 of the flow channel 13, the bottom surface of the buffer chamber 214 forms the bearing surface 212 of the seal 20, and the bottom surface of the buffer chamber 214 faces towards the inlet end 11 of the flow channel 13, so that the pressure of the medium entering the buffer chamber 214 can act on the bottom surface of the buffer chamber 214 to push the seal 20 to move away from the inlet end 11. The first water channel 211 may be distributed on a sidewall of the buffer cavity 214. Because the force-bearing surface 212 needs to be ensured to be capable of receiving enough pressure, the gap between the outer peripheral surface of the water filtering body 21 and the inner peripheral surface of the flow channel 13 is smaller, so that the medium can smoothly flow in the angle valve 100, a plurality of first water through grooves 211 can be distributed along the circumferential direction of the buffer cavity 214, and the first water through grooves 211 extend from the circumferential side wall of the buffer cavity 214 to the edge of the bottom wall, so that most of the medium can flow out of the buffer cavity 214 through the first water through grooves 211 at the part of the bottom surface edge of the buffer cavity 214 and then flow to the flow holes 15.

The water filter 21 has a connection 213 at an end facing away from the inlet end 11, the connection 213 being adapted to connect the water filter 21 with the water plug 22. The connection between the water filtering body 21 and the water passing plug 22 may be a clamping connection, a screw connection or a magnetic attraction, but is not limited thereto. As shown in fig. 4 and 6, in the embodiment of the present application, the connection between the water filtering body 21 and the water through plug 22 is taken as an example of threaded connection, and the connection portion 213 of the water filtering body 21 may be a section of threaded column, and the water through plug 22 has a threaded sleeve matched with the threads of the connection column. The threaded sleeve portion of the water passing plug 22 may be provided through the flow hole 15 such that the length of the threaded sleeve portion of the water passing plug 22 corresponds to the stroke of the sealing member 20 reciprocally moving within the flow channel 13. Since it is necessary to secure the coupling member to be engaged with the angle valve body 10, the end of the coupling member can be abutted against the end surface of the water passing plug 22 to push the sealing member 20 to move, and the gap between the outer circumferential surface of the maximum diameter of the water passing plug 22 and the inner circumferential surface of the flow channel 13 is small, the second water passing groove 221 is provided in the water passing plug 22, and the second water passing groove 221 penetrates the flow hole 15, so that the medium flowing out of the first water passing groove 211 can flow to the water outlet end through the second water passing groove 221. The second water passage 221 extends from the peripheral surface of the threaded sleeve portion of the water passage plug 22 to the end surface of the water passage plug 22 on the side facing the outlet end 12, so that the medium flowing into the angle valve 100 from the inlet end 11 of the flow passage 13 flows out of the seal 20 through the buffer chamber 214, the first water passage 211, and the end surface of the second water passage 221 on the side of the water passage plug 22 facing the outlet end 12, and then flows toward the outlet end 12 of the flow passage 13, as shown in fig. 3.

As shown in fig. 4 and 5, in some embodiments, the seal 20 may also include a seal ring 23. The sealing ring 23 can ensure tightness of the closure of the through-hole 15 when the sealing member 20 closes the through-hole 15. The sealing ring 23 may be sleeved on the connecting portion 213 of the water filtering body 21, and is located at one end of the water through plug 22 facing the water filtering body 21. The sealing ring 23 may be sleeved at one end of the connecting portion 213 away from the water through plug 22, and after the water through plug 22 is connected with the connecting portion 213, one end of the water through plug 22 facing the water filtering body 21 abuts against the sealing member 20. When the sealing member 20 has the second inclined surface 231 engaged with the first inclined surface 141, the second inclined surface 231 is formed at a side of the sealing member 20 facing the water passing plug 22.

As shown in fig. 2, 3, and 9, in some embodiments, the angle valve 100 further includes a housing assembly 30 and a connecting body 40. The housing assembly 30 is integrally formed in a tubular structure, the angle valve body 10 is embedded in one end of the housing assembly 30, and the connecting body 40 is embedded in the other end of the housing assembly 30 to push the sealing member 20 to open the flow hole 15. Wherein the connection body 40 is used to connect the rear end of the angle valve 100 to the product. When the connecting body 40 and the angle valve body 10 are embedded in the housing assembly 30, the embedded position of the connecting body 40 in the housing assembly 30 needs to be satisfied: when the sealing member 20 of the angle valve body 10 moves in a direction approaching the connection body 40 until the water passing plug 22 abuts against the end of the connection body 40, the sealing member 20 is in a state of opening the flow hole 15, so that after the connection body 40 is matched with the housing assembly 30, the medium flowing into the angle valve 100 can flow to the rear end through the flow hole 15 and then the connection body 40 to connect products. It should be understood that the connection body 40 is of a tubular structure, and the specific shape of the connection body 40 is not limited in this embodiment, for example, the connection body 40 may be of a straight tube structure or a bent tube structure, but is not limited thereto, and as shown in fig. 1 to 3, the bent tube structure in which the connection body 40 is of a right angle shape is exemplified in the embodiment of the present application.

As shown in fig. 2 and 8, in some embodiments, housing assembly 30 may include an outer housing 31 and a resilient collar 32 disposed within outer housing 31. The outer peripheral surface of the connecting body 40 has a circumferentially extending locking groove 41, and the locking groove 41 is adapted to engage with the elastic collar 32.

As shown in fig. 11. The locking groove 41 may be a groove connecting the outer circumferential surface of the main body 40. The locking groove 41 extends along the outer circumferential surface of the connecting body 40 for one turn, and after the elastic collar 32 is engaged with the locking groove 41, the elastic collar 32 can restrict the connecting body 40 from moving along the central axis of the outer housing 31, but not restrict the connecting body 40 from rotating around the central axis of the outer housing 31. Thus, after the connection body 40 is connected with the housing assembly 30 of the angle valve 100, the connection body 40 can be freely rotated, and the direction of the connection body 40 for connecting one end of the rear end product can be freely adjusted, so that the flexibility of using the angle valve 100 is improved. When the connection body 40 is engaged with the outer case 31, the end portion of the connection body 40 presses the elastic collar 32 to deform the elastic collar 32, the inner ring of the elastic collar 32 moves away from the connection body 40 in the radial direction of the outer case 31, and along with the engagement of the connection body 40, the inner ring edge of the elastic collar 32 abuts against the outer peripheral surface of the connection body 40 until the inner ring edge of the elastic collar 32 engages in the engagement groove 41, and the connection body 40 and the outer case 31 are connected.

As shown in fig. 4 and 9, one end of the outer case 31 for connection with the angle valve body 10 may be provided with an internal thread, and the angle valve body 10 is provided with an external thread engaged with the internal thread, so that the angle valve body 10 is fixedly connected to one end of the outer case 31. The housing assembly 30 may also include a seal ring 36. The sealing ring 36 is located at an end of the outer housing 31 where the angle valve body 10 protrudes into the outer housing 31, the sealing ring 36 being used to seal a fit gap between the angle valve body 10 and the outer housing 31.

As shown in FIG. 4, in some embodiments, the angle valve 100 may also include a trim ring 50. The decoration ring 50 is sleeved on the angle valve body 10, and after the angle valve body 10 is connected with the outer shell 31, the end of the outer shell 31 abuts against one side surface of the decoration ring 50.

When the angle valve 100 includes the connection body 40, the rear end connection product of the angle valve 100 is connected with the angle valve 100 through the connection body 40, in order to facilitate connection and disconnection of the rear end connection product of the angle valve 100 with the angle valve 100, the connection body 40 may be connected with the outer case 31 in a quick-release structure. In some embodiments, the housing assembly 30 further includes a trip sleeve 33 and a quick release sleeve 34. The trip sleeve 33 is fixedly disposed in the housing, and the trip sleeve 33 has a guiding surface 331. The outer edge of spring collar 32 may be engaged with guide surface 331. The quick-release sleeve 34 is movably embedded in the outer housing 31 and is used for being matched with one end of the connecting body 40, and the quick-release sleeve 34 is used for pushing the elastic collar 32 to move along the guide surface 331 through movement so as to enable the elastic collar 32 to be separated from the clamping groove 41, so that quick-release of the connecting body 40 can be realized.

Wherein, when the quick release sleeve 34 pushes the elastic collar 32 to move along the guiding surface 331, the elastic collar 32 can be expanded through the inner ring to be separated from the clamping groove 41. For example, as shown in fig. 10, in some embodiments, an edge of a side of elastic collar 32 that cooperates with guide surface 331 may have a plurality of open grooves 321, where open grooves 321 intersect a straight line on two sides adjacent to the opening, for example, but not limited to, open grooves 321 may be trapezoidal or triangular. In this way, when the quick release sleeve 34 pushes the elastic collar 32 to move along the guide surface 331, the guide surface 331 can press the open groove 321 and the two adjacent sides of the opening to each other, so that the side of the elastic collar 32 opposite to the opening of the open groove 321 is opened, the inner ring of the elastic collar 32 is enlarged, and the inner ring is separated from the clamping groove 41 of the connecting body 40. It will be appreciated that to achieve expansion of the inner ring of spring collar 32, spring collar 32 also has a squeeze groove 322 opening toward the inner ring, and that when the inner ring of spring collar 32 expands, the squeeze groove 322 and the sides adjacent to the opening are also adjacent to each other. When the elastic collar 32 moves along the guide surface 331, the guide surface 331 presses the open slot 321 and two adjacent sides of the opening to approach each other, and it can be understood that the elastic collar 32 moves from the large diameter end of the guide surface 331 to the small diameter end, for example, the guide surface 331 is a conical surface, so that the large diameter end of the guide surface 331 faces the outer housing 31 to be used for embedding one end of the connecting body 40, and the small diameter end of the guide surface 331 faces the outer housing 31 to be used for embedding one end of the angle valve main body 10.

As shown in fig. 4 and 8, in some implementations, the housing assembly 30 further includes an inner liner 35. The inner peripheral surface of the inner bush 35 has a first limit surface 351 facing the release sleeve 33, the quick release sleeve 34 has a second limit surface 341 mating with the first limit surface 351, and the first limit surface 351 and the second limit surface 341 are configured to prevent the quick release sleeve 34 from being separated from the outer housing 31.

The end of the outer case 31 mated with the connection body 40 may be provided with a limit protrusion 311, such that the inner bushing 35 is embedded into the outer case 31 from the end of the outer case 31 mated with the angle valve body 10, one end of the inner bushing 35 abuts against the limit protrusion 311, the other end abuts against the trip bush 33, and one end of the trip bush 33 facing away from the inner bushing 35 abuts against the seal ring 36, and one end of the seal ring 36 facing away from the trip bush 33 abuts against the end of the angle valve body 10, whereby the inner bushing 35, the trip bush 33 and the seal ring 36 are fixed in the outer case 31 in the axial direction along the outer case 31.

Because the quick release sleeve 34 is movably engaged with the outer housing 31, in order to ensure the stability of the connection between the connecting body 40 and the outer housing 31, in some embodiments, an end of the quick release sleeve 34 facing away from the release sleeve 33 has a limiting flange 342. The housing assembly 30 may also include a stop collar 37. The stop collar 37 is detachably disposed on the quick release sleeve 34, and the stop collar 37 is disposed between the outer housing 31 and the stop flange 342 to prevent the quick release sleeve 34 from moving.

When the connecting body 40 is detached from the outer housing 31, the quick release sleeve 34 needs to be moved, so the stop ring 37 needs to be detachably sleeved on the quick release sleeve 34, for example, in some embodiments, the stop ring 37 may be an elastic split ring, but is not limited thereto. It will be appreciated that when the stop collar 37 is inserted between the outer housing 31 and the stop flange 342, the second stop surface 341 of the quick release sleeve 34 cooperates with the first stop surface 351, so that the stop collar 37 prevents the quick release sleeve 34 from moving in a direction approaching the outer housing 31, and the first stop surface 351 prevents the quick release sleeve 34 from moving in a direction separating from the outer housing 31, thereby fixing the quick release sleeve 34 to ensure the connection stability of the connecting body 40 and the outer housing 31.

The foregoing description is only the embodiments of the present application, and is not intended to limit the scope of the patent application, and all equivalent structures or equivalent processes using the descriptions and the contents of the present application or other related technical fields are included in the scope of the patent application.
