Description

Technical Field

[0001] This utility model relates to the field of three-way valve technology, specifically a novel adjustable three-way valve. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting flow, or overflowing and relieving pressure. A three-way valve is a type of valve with three flow ports, usually referring to a valve with one inlet and two outlets. Its core function is to change the direction of medium flow, and it is widely used in scenarios such as petroleum, chemical, and water supply and drainage where pipeline switching is required.

[0003] Existing three-way valves are typically controlled by a single switch to close the entire valve. This means that one valve controls the opening and closing of one inlet and two outlets. It is inconvenient to individually adjust the opening and closing of one inlet and two outlets with a single valve. Therefore, it is difficult to control the two outlets when they require different flow rates, thus reducing the practicality of the three-way valve. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a novel adjustable three-way valve, which solves the problem that it is inconvenient to individually adjust and control one inlet and two outlet ends of a three-way valve during use.

[0006] (II) Technical Solution

[0007] To facilitate the independent on / off control of one inlet and two outlet ends of the aforementioned three-way valve during use, this utility model provides the following technical solution: A novel adjustable three-way valve includes a valve body, an inlet valve pipe fixed to one end of the valve body, and a first outlet valve pipe and a second outlet valve pipe respectively fixed to the other two ends of the valve body. An adjustment box is fixed to the valve body by bolts, and an adjustment structure is provided inside the adjustment box. A main valve shaft is provided on the valve body, an inlet valve shaft is provided on the inlet valve pipe, and outlet valve shafts are provided on both the first and second outlet valve pipes. An inlet ball valve is provided inside the inlet valve pipe, and an outlet ball valve is provided inside both the first and second outlet valve pipes.

[0008] The adjustment structure includes a support frame, which is fixedly connected to the adjustment box. The main valve shaft is rotatably connected to the middle of the support frame via a bearing. A main gear ring is fixed on the main valve shaft. A linkage gear ring is rotatably mounted on the outer side of the support frame via a pivot pin. Rotary cylinders are rotatably mounted on the inlet valve pipe, the first outlet valve pipe, and the second outlet valve pipe. A rectangular vertical groove is opened inside the rotary cylinder. A spring is installed inside the vertical groove. A protrusion slide plate slides inside the vertical groove. A lifting sleeve is fixed above the protrusion slide plate. An adapter sleeve is rotatably mounted on the outer end of the support frame via a bearing. A lower tooth is fixed above the lifting sleeve. An upper tooth is fixed below the adapter sleeve. A driven gear ring is fixed on the surface of the adapter sleeve.

[0009] Preferably, the rotating cylinder on one side of the inlet valve pipe is fixedly connected to the inlet ball valve, and the rotating cylinder on one side of the first outlet valve pipe and the second outlet valve pipe is fixedly connected to the outlet ball valve inside them.

[0010] Preferably, the convex slide plate consists of a central cylindrical plate and two rectangular sliders on both sides. The rectangular sliders are slidably connected to the rectangular vertical groove, the cylindrical plate is slidably connected to the rotating cylinder, and the upper and lower ends of the spring are fixedly connected to the convex slide plate and the rotating cylinder, respectively.

[0011] Preferably, the lower teeth are arranged along the circumferential direction of the lifting sleeve, and the upper teeth are arranged along the circumferential direction of the adapter sleeve.

[0012] Preferably, the gap between two adjacent lower teeth forms the lower alveolar ridge, and the gap between two adjacent upper teeth forms the upper alveolar ridge. The outer portions of the lower and upper teeth are triangular and the inner portions are rectangular. The outer portions of the lower and upper alveolar ridges are rectangular and the inner portions are triangular. Furthermore, the lower teeth are adapted to the upper alveolar ridge, and the upper teeth are adapted to the lower alveolar ridge.

[0013] Preferably, the main gear ring meshes with the linkage gear ring, and the linkage gear ring meshes with the driven gear ring.

[0014] Preferably, both the inlet valve shaft and the outlet valve shaft pass through the adapter sleeve and are movably connected to the adapter sleeve. The inlet valve shaft is fixedly connected to the lifting sleeve on one side of the inlet valve pipe, and the outlet valve shaft is fixedly connected to the lifting sleeve on one side of the first outlet valve pipe and the second outlet valve pipe, respectively.

[0015] Compared with the prior art, this utility model provides a novel adjustable three-way valve, which has the following beneficial effects:

[0016] 1. This new type of adjustable three-way valve can drive the main gear ring to rotate by rotating the main valve shaft. Through the linkage gear, it can drive the driven gear rings on one side of the inlet valve pipe, the first outlet valve pipe, and the second outlet valve pipe to rotate respectively, so that the lifting sleeve and the adapter sleeve can rotate at the same time. In turn, the rotating cylinder on one side of the inlet valve pipe can drive the inlet ball valve to rotate, and the rotating cylinder on one side of the first outlet valve pipe and the second outlet valve pipe can drive the outlet ball valve on their respective sides to rotate. Thus, the inlet valve pipe, the first outlet valve pipe, and the second outlet valve pipe can be opened at the same time, so that water can enter the inlet valve pipe and water can be discharged from the first outlet valve pipe and the second outlet valve pipe at the same time.

[0017] 2. This new type of adjustable three-way valve allows for individual control of the inlet valve pipe, the first outlet valve pipe, and the second outlet valve pipe. First, press down on the inlet valve shaft or outlet valve shaft. The lower tooth disengages from the upper tooth, allowing the lifting sleeve to slide downwards within the vertical groove via the convex sliding plate. Then, rotating the inlet valve shaft or outlet valve shaft rotates the lifting sleeve. The lifting sleeve, through the convex sliding plate, drives the rotating drum. Therefore, the rotating drum on one side of the inlet valve pipe drives the inlet ball valve to rotate, allowing for individual control of the inlet valve pipe's opening and closing. Similarly, the rotating drum on one side of the first or second outlet valve pipe drives the outlet ball valve to rotate, allowing for individual control of the opening and closing of the first or second outlet valve pipe.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] Please see Figure 1-5 This utility model provides a novel adjustable three-way valve, including a valve body 1, an inlet valve pipe 2 fixed to one end of the valve body 1, a first outlet valve pipe 3 and a second outlet valve pipe 4 fixed to the other two ends of the valve body 1 respectively, an adjustment box 5 fixed to the valve body 1 by bolts, an adjustment structure provided inside the adjustment box 5, a main valve shaft 6 provided on the valve body 1, an inlet valve shaft 7 provided on the inlet valve pipe 2, an outlet valve shaft 8 provided on both the first outlet valve pipe 3 and the second outlet valve pipe 4, an inlet ball valve 9 provided inside the inlet valve pipe 2, and an outlet ball valve 10 provided inside both the first outlet valve pipe 3 and the second outlet valve pipe 4.

[0026] The regulating structure includes a support frame 51, which is fixedly connected to the regulating box 5. The main valve shaft 6 is rotatably connected to the middle of the support frame 51 via a bearing. A main gear ring 52 is fixed on the main valve shaft 6. A linkage gear ring 53 is rotatably mounted on the outer side of the support frame 51 via a pivot pin. Rotary cylinders 54 are rotatably mounted on the inlet valve pipe 2, the first outlet valve pipe 3, and the second outlet valve pipe 4. A rectangular vertical groove 55 is provided inside the rotary cylinder 54. A spring 56 is installed inside the vertical groove 55. A protrusion slide plate 57 slides inside the vertical groove 55. A lifting sleeve 58 is fixed above the protrusion slide plate 57. An adapter sleeve 59 is rotatably mounted on the outer end of the support frame 51 via a bearing. The upper part of the lifting sleeve 58 is fixed with a lower tooth 510, and the lower part of the adapter sleeve 59 is fixed with an upper tooth 511. The surface of the adapter sleeve 59 is fixed with a driven tooth ring 512. The main tooth ring 52 is driven to rotate by the main valve shaft 6. The main tooth ring 52 can drive the lifting sleeve 58 to rotate by meshing with the linkage tooth ring 53, and the linkage tooth ring 53 can mesh with the driven tooth ring 512. In turn, the lifting sleeve 58 can drive the rotating drum 54 to rotate by the protrusion slide plate 57, so that the rotating drum 54 can drive the inlet ball valve 9 and the outlet ball valve 10 to rotate, thereby controlling the opening and closing of the inlet valve pipe 2, the first outlet valve pipe 3 and the second outlet valve pipe 4.

[0027] Furthermore, the rotating cylinder 54 on one side of the inlet valve pipe 2 is fixedly connected to the inlet ball valve 9, and the rotating cylinder 54 on one side of the first outlet valve pipe 3 and the second outlet valve pipe 4 is fixedly connected to the outlet ball valve 10 inside it, so that the rotating cylinder 54 on one side of the inlet valve pipe 2 can drive the inlet ball valve 9 to rotate independently, and the rotating cylinder 54 on one side of the first outlet valve pipe 3 and the second outlet valve pipe 4 can drive the outlet ball valve 10 to rotate independently.

[0028] Furthermore, the convex slide plate 57 consists of a cylindrical plate in the middle and two rectangular sliders on both sides. The rectangular sliders are slidably connected to the rectangular vertical groove 55, and the cylindrical plate is slidably connected to the rotating cylinder 54. The upper and lower ends of the spring 56 are fixedly connected to the convex slide plate 57 and the rotating cylinder 54 respectively, so that the convex slide plate 57 can only move in the vertical direction inside the vertical groove 55, and the convex slide plate 57 can also drive the rotating cylinder 54 to rotate at the same time.

[0029] Furthermore, the lower teeth 510 are arranged along the circumference of the lifting sleeve 58, and the upper teeth 511 are arranged along the circumference of the adapter sleeve 59. Multiple lower teeth 510 are arranged along the circumference of the lifting sleeve 58, and multiple upper teeth 511 are arranged along the circumference of the adapter sleeve 59, so that the lower teeth 510 and the upper teeth 511 can engage after the lifting sleeve 58 is rotated to any position.

[0030] Furthermore, the gap between two adjacent lower teeth 510 forms the lower alveolar ridge, and the gap between two adjacent upper teeth 511 forms the upper alveolar ridge. The outer portions of the lower teeth 510 and upper teeth 511 are triangular, and the inner portions are rectangular. The outer portions of the lower alveolar ridge and upper alveolar ridge are rectangular, and the inner portions are triangular. The lower teeth 510 fit into the upper alveolar ridge, and the upper teeth 511 fit into the lower alveolar ridge. The lower and upper alveolar ridges are relatively deep, and the lower teeth 510 and upper teeth 511 are relatively high. Therefore, when the lower teeth 510 are inserted into the upper alveolar ridge and the upper teeth 511 are inserted into the lower alveolar ridge, one triangular end of the lower teeth 510 is inserted into the triangular groove of the upper alveolar ridge, and the rectangular portion of the lower teeth 510 fits into the rectangular portion of the upper alveolar ridge. The triangular portion of the upper teeth 511... One end is inserted into the triangular groove of the lower tooth socket, and the rectangular part of the tooth 511 fits against the rectangular part of the lower tooth socket. When the adapter sleeve 59 drives the lifting sleeve 58 to rotate in the circumferential direction, the rectangular part of the upper tooth 511 can generate a circumferential thrust on the rectangular part of the lower tooth 510, which can make the lower tooth 510 and the upper tooth 511 bite each other. Therefore, the lifting sleeve 58 and the adapter sleeve 59 can be circumferentially limited, and the lifting sleeve 58 can move up and down. When the adapter sleeve 59 drives the lifting sleeve 58 to rotate through the lower tooth 510 and the upper tooth 511, the lower tooth 510 will not disengage from the upper tooth 511. Furthermore, by setting the outer part of the lower tooth 510 and the upper tooth 511 to a triangular shape, it is easier for the lower tooth 510 and the upper tooth 511 to be inserted into each other in the vertical direction.

[0031] Furthermore, the main gear ring 52 meshes with the linkage gear ring 53, and the linkage gear ring 53 meshes with the driven gear ring 512, so that the main gear ring 52 can drive the linkage gear ring 53 to rotate, and the linkage gear ring 53 can drive the driven gear ring 512 to rotate. Thus, the driven gear ring 512 can drive the rotating drum 54 to rotate through the adapter sleeve 59 and the lifting sleeve 58, and thus the rotating drum 54 can drive the inlet ball valve 9 and the outlet ball valve 10 to rotate respectively.

[0032] Furthermore, both the inlet valve shaft 7 and the outlet valve shaft 8 pass through the adapter sleeve 59 and are movably connected to the adapter sleeve 59. The inlet valve shaft 7 is fixedly connected to the lifting sleeve 58 on one side of the inlet valve pipe 2, and the outlet valve shaft 8 is fixedly connected to the lifting sleeve 58 on one side of the first outlet valve pipe 3 and the second outlet valve pipe 4, respectively. When the inlet valve shaft 7 or the outlet valve shaft 8 is rotated, the lifting sleeve 58 can drive the rotating drum 54 to rotate. In turn, the rotating drum 54 can drive the inlet ball valve 9 inside the inlet valve pipe 2 and the outlet ball valve 10 inside the first outlet valve pipe 3 or the second outlet valve pipe 4 to rotate. By setting an inlet ball valve 9 inside the inlet valve pipe 2 and an outlet ball valve 10 inside the first outlet valve pipe 3 or the second outlet valve pipe 4, the sealing performance of the valve body 1 when closed can be improved by setting multiple valves.

[0033] The working principle of this utility model is as follows: During use, keeping the inlet valve shaft 7 and outlet valve shaft 8 stationary, rotating the main valve shaft 6 drives the main gear ring 52 to rotate. The main gear ring 52, through meshing with three linkage gear rings 53, drives the driven gear rings 512 on one side of the inlet valve pipe 2, the first outlet valve pipe 3, and the second outlet valve pipe 4 to rotate respectively. The driven gear rings 512, through the meshing of the lower teeth 510 and the upper teeth 511, enable the lifting sleeve 58 and the adapter sleeve 59 to rotate simultaneously. Furthermore, the convex sliding plate 57 drives the rotating drum 54 to rotate, thereby rotating the inlet valve pipe 2... The rotating drum 54 on one side can drive the inlet ball valve 9 to rotate. The rotating drum 54 on the side of the first outlet valve pipe 3 and the second outlet valve pipe 4 can drive the outlet ball valve 10 on their respective sides to rotate, thereby simultaneously opening the inlet valve pipe 2, the first outlet valve pipe 3, and the second outlet valve pipe 4, allowing water to enter the inlet valve pipe 2 and water to exit the first outlet valve pipe 3 and the second outlet valve pipe 4 at the same time. Therefore, it is possible to control the opening and closing of one inlet end and two outlet ends of the regulating valve body 1 at the same time. In addition, when it is necessary to control the opening and closing of the inlet valve pipe 2, the first outlet valve pipe 3, and the second outlet valve pipe 4 individually, At this time, keeping the main valve shaft 6 stationary, first press down the inlet valve shaft 7 or the outlet valve shaft 8. The inlet valve shaft 7 or the outlet valve shaft 8 will drive the lifting sleeve 58 to move downward. At this time, the lower tooth 510 will disengage from the upper tooth 511, and the lifting sleeve 58 can drive the protrusion slide plate 57 to slide downward inside the vertical groove 55 and compress the spring 56. Then, rotating the inlet valve shaft 7 or the outlet valve shaft 8 can drive the lifting sleeve 58 to rotate. In turn, the lifting sleeve 58 can drive the rotating drum 54 to rotate through the protrusion slide plate 57. Therefore, the rotating drum 54 on the side of the inlet valve pipe 2 can drive the inlet ball valve 9 to rotate, and The switch of the inlet valve pipe 2 can be controlled independently. The rotating drum 54 on one side of the first outlet valve pipe 3 or the second outlet valve pipe 4 can drive the outlet ball valve 10 to rotate, and the switch of the first outlet valve pipe 3 or the second outlet valve pipe 4 can be controlled independently. Then, the inlet valve shaft 7 or the outlet valve shaft 8 can be released manually. As mentioned above, the spring 56 extends and drives the convex slide plate 57 to move upward. The convex slide plate 57 drives the lifting sleeve 58 to move upward, and the lower tooth 510 and the upper tooth 511 are engaged again. Therefore, the switch of the inlet valve pipe 2, the first outlet valve pipe 3 and the second outlet valve pipe 4 can be controlled independently.
