Description

Technical Field

[0001] This utility model relates to the field of two-way valve technology, specifically a two-way valve with a swing valve core mechanism. Background Technology

[0002] A two-way valve is a control valve with two pipelines; its basic characteristic is that it can switch on and off in both directions; when the two pipelines can only achieve conduction in one direction, it is called a one-way valve.

[0003] In the field of two-way valve technology, traditional two-way valves have many shortcomings. Their structural design is often relatively simple, with poor adaptability to the inlet direction. Most can only achieve the blocking function when water enters from a specific direction; once the inlet direction changes, they are unable to effectively stop the water flow. This is extremely inconvenient in complex pipeline layouts and multi-directional water flow conditions, failing to meet comprehensive fluid control needs. Regarding the regulating function, traditional two-way valves typically isolate the water flow regulation and inlet blocking functions, failing to automatically achieve blocking based on different inlet directions during water flow regulation. This results in cumbersome operation, a lack of integration, and difficulty in accurately controlling fluid flow and on / off states.

[0004] In view of this, a two-way valve with a rocking valve core mechanism is provided to overcome the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a two-way valve with a rocking valve core mechanism to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a two-way valve with a swing-type valve core mechanism, including a valve body and a rotating shaft rotatably connected to the top of the valve body. A handle is installed on the outer wall of the rotating shaft, a scale plate is installed on the top of the valve body, a connecting block is rotatably connected to the bottom end of the rotating shaft, rotating rods rotatably connected to the rotating shaft are installed on both sides of the connecting block, and a valve core located in the valve body is installed at the bottom end of the connecting block. The bottom of the cavity of the valve body is provided with a movable groove that adapts to the swinging process of the valve core.

[0007] Furthermore, a sealing gasket and a limiting block are provided on the top of the valve body, and the sealing gasket and the limiting block are respectively located at the bottom of the scale plate and the top of the handle.

[0008] Furthermore, one end of the handle is integrally formed with a pointer, and a through groove is formed through the handle, through which the handle is connected to the rotating shaft.

[0009] Furthermore, the top of the scale plate is integrally formed with scale marks, and the top of the scale plate has an arc-shaped groove and a straight groove. The top of the scale plate also has a through hole that is rotatably connected to the outer wall of the rotating shaft.

[0010] Furthermore, an observation port is provided through the top of the scale plate, and two limiting posts are installed on the top of the scale plate.

[0011] Furthermore, the inner wall of the valve body is provided with a first sliding groove and a second sliding groove from top to bottom. The inner walls of the second sliding groove and the first sliding groove are respectively slidably connected to a first rack and a second rack. One end of the first rack is connected to an arc-shaped plate. The inner wall of the valve body is provided with a fitting groove that matches the arc-shaped plate. A compression spring is installed between the first sliding groove and the second rack. The valve body is rotatably connected to a gear that meshes with the first rack and the second rack.

[0012] Furthermore, rubber pads are installed on both sides of the valve core.

[0013] Furthermore, the inner wall of the first chute is provided with a guide groove, and the inner wall of the guide groove is slidably connected with an anti-detachment block connected to the second rack.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Rotating the handle causes the shaft to drive the valve core to rotate via the connecting block and the rotating rod. During the rotation, not only can the amount of water passing through the valve body be adjusted, but also, after the valve core rotates 90°, water entering from either the left or right direction of the valve body can cause the valve core to swing left and right. Thus, it can automatically block water entering from any direction, and the greater the water pressure, the better the blocking effect. By setting a movable groove, the problem of motion interference of the valve core during the swinging process is avoided.

[0016] After the valve core swings to one side, it will contact the second rack on that side, and through the gear, it will drive the first rack to approach the valve core, thereby inserting the arc plate into the rubber pad, thus improving the blocking effect of the valve core. The elasticity of the compression spring will then allow it to return to its original position. When there is no water flow, it is convenient to readjust the rotation angle of the valve core to control the amount of water passing through the valve body. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 This utility model provides a technical solution:

[0027] See Figures 1-7As shown, a two-way valve with a rocking valve core mechanism includes a valve body 1, a rotating shaft 2 rotatably connected to the top of the valve body 1, a handle 3 mounted on the outer wall of the rotating shaft 2, a scale plate 4 mounted on the top of the valve body 1, a connecting block 5 rotatably connected to the bottom end of the rotating shaft 2, rotating rods 6 rotatably connected to the rotating shaft 2 mounted on both sides of the connecting block 5, and a valve core 7 located inside the valve body 1 mounted at the bottom end of the connecting block 5. A movable groove 8 adapted to the rocking motion of the valve core 7 is provided at the bottom of the cavity of the valve body 1. A sealing gasket 9 and a limiting block 10 are provided on the top of the valve body 1, located at the bottom of the scale plate 4 and the top of the handle 3, respectively. The sealing gasket 9 seals the gap between the valve body 1 and the rotating shaft 2, ensuring the sealing effect of the top of the valve body 1. The limiting block 10 prevents the handle 3 from disengaging, thereby preventing the scale plate 4 and the sealing gasket 9 from disengaging, thus ensuring the overall sealing effect. The integrity of the body structure is ensured; one end of the handle 3 is integrally formed with a pointer 11, and a through groove 12 is formed through the handle 3, which is connected to the rotating shaft 2 through the through groove 12; the top of the scale plate 4 is integrally formed with a scale mark 14, and the top of the scale plate 4 has an arc-shaped groove 15 and a straight groove 16, and the top of the scale plate 4 has a through hole 13 that is rotatably connected to the outer wall of the rotating shaft 2; the pointer 11, scale mark 14, arc-shaped groove 15 and straight groove 16 are used in combination to facilitate the control of the rotation angle of the valve core 7, and the rotation can be seen intuitively; the top of the scale plate 4 has an observation port 17, and two limit posts 18 are installed on the top of the scale plate 4; by setting the observation port 17, the user can see more intuitively how much angle the valve core 7 has rotated; by setting the limit posts 18, the rotation process of the valve core 7 is limited, ensuring the adjustment accuracy;

[0028] Rotating the handle 3 causes the rotating shaft 2 to drive the valve core 7 to rotate via the connecting block 5 and the rotating rod 6. During the rotation, not only can the amount of water passing through the valve body 1 be adjusted, but also, after the valve core 7 rotates 90°, water entering the valve body 1 from any direction will cause the valve core 7 to swing left and right. Thus, the effect of automatically blocking water entering from any direction can be achieved, and the greater the water pressure, the better the blocking effect. By setting the movable groove 8, the problem of motion interference of the valve core 7 during the swinging process is avoided.

[0029] Furthermore, the inner wall of the valve body 1 is provided with a first sliding groove 19 and a second sliding groove 20 sequentially from top to bottom. The inner walls of the second sliding groove 20 and the first sliding groove 19 are respectively slidably connected to a first rack 21 and a second rack 22. One end of the first rack 21 is connected to an arc-shaped plate 23. The inner wall of the valve body 1 is provided with a fitting groove 26 that matches the arc-shaped plate 23. A compression spring 24 is installed between the first sliding groove 19 and the second rack 22. The valve body 1 is rotatably connected to a spring that meshes with the first rack 21 and the second rack 22. The gear 25 is connected to the valve core 7; rubber pads 27 are installed on both sides of the valve core 7. By setting the rubber pads 27, the arc plate 23 can be inserted into it to improve the blocking effect of the valve core 7; the inner wall of the first slide groove 19 is provided with a guide groove 28, and the inner wall of the guide groove 28 is slidably connected with an anti-detachment block 29 connected to the second rack 22; the guide groove 28 limits the movement of the anti-detachment block 29, and thus limits the movement of the second rack 22, so as to avoid the problem of motion interference caused by the second rack 22 extending too far out of the first slide groove 19;

[0030] After the valve core 7 swings to one side, it will abut against the second rack 22 on that side, and drive the first rack 21 to approach the valve core 7 through the gear 25, so that the arc plate 23 is inserted into the rubber pad 27, thereby improving the blocking effect of the valve core 7. The compression spring 24 is used to return to its original position and move away. When there is no water flow, it is convenient to readjust the rotation angle of the valve core 7 to control the amount of water passing through the valve body 1.

[0031] Working principle:

[0032] Rotating the handle 3 causes the rotating shaft 2 to drive the valve core 7 to rotate via the connecting block 5 and the rotating rod 6. During the rotation, not only can the amount of water passing through the valve body 1 be adjusted, but also, after the valve core 7 rotates 90°, water entering the valve body 1 from any direction will cause the valve core 7 to swing left and right. Thus, the effect of automatically blocking water entering from any direction can be achieved, and the greater the water pressure, the better the blocking effect. By setting the movable groove 8, the problem of motion interference of the valve core 7 during the swinging process is avoided.

[0033] After the valve core 7 swings to one side, it will abut against the second rack 22 on that side, and drive the first rack 21 to approach the valve core 7 through the gear 25, so that the arc plate 23 is inserted into the rubber pad 27, thereby improving the blocking effect of the valve core 7. The compression spring 24 is used to return to its original position and move away. When there is no water flow, it is convenient to readjust the rotation angle of the valve core 7 to control the amount of water passing through the valve body 1.
