Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel four-way booster valve. Background Art

[0002] Four-way booster valves are primarily based on fluid dynamics and valve core displacement control. When water or other fluid passes through the valve, the valve core shifts according to the set pressure, changing the direction and flow rate of the fluid. During the boosting process, the displacement of the valve core compresses the fluid, increasing its pressure and achieving the desired pressure boost. Four-way booster valves ensure a stable water supply, improve water efficiency, and protect related equipment from pressure fluctuations.

[0003] As the valve is used for a long time, impurities carried by various flowing media will accumulate in the valve body, causing the valve body to become clogged. To solve this problem, a filter structure needs to be installed in the valve body. However, the internal filter structure of the existing four-way booster valve is usually welded to the valve body, making it difficult to disassemble and replace the filter structure for cleaning. Therefore, this application proposes a new four-way booster valve. Utility Model Content

[0023] As described in the background art, the internal filter structure of the existing four-way booster valve is usually welded to the valve body, which makes it difficult to disassemble and replace the filter structure or clean it.

[0024] In order to solve this technical problem, the utility model provides a novel four-way booster valve, which is used to ensure a stable supply of flowing medium;

[0025] It includes a valve body 1, one end of the valve body body 1 is provided with a water inlet, the other end of the valve body body 1 is provided with a water outlet, the inner side of the valve body body 1 near the water inlet is threadedly connected to an inner filter sleeve 2, the inner side of the inner filter sleeve 2 is fixedly connected to a stainless steel filter screen 3, one end of the inner filter sleeve 2 and located on the inner side of the valve body 1 is provided with a built-in ring seat 5, the built-in ring seat 5 is fixedly connected to the valve body 1, an annular groove 4 is opened on the outer side of the inner filter sleeve 2 near the end of the built-in ring seat 5, and a limiting component is provided on the inner side of the built-in ring seat 5 and located on the outer side of the annular groove 4.

[0026] The new four-way booster valve provided by the utility model drives the external ring seat 10 to move by rotating the hand-tightened screw barrel 12, and then drives the screw 11 to be pulled out from the inner side of the hollow screw barrel 7, so that the end of the limit support block 8 away from the hollow screw barrel 7 is moved out from the inner side of the annular groove 4, thereby releasing the limit on the position of the inner filter sleeve 2, making it convenient to rotate the inner filter sleeve 2 to remove it from the valve body 1. The overall disassembly and assembly operation is convenient and quick, and it is easy to replace or clean the stainless steel filter screen 3.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0029] Example 1:

[0030] Please refer to Figure 1-5 A new type of four-way booster valve includes a valve body 1. One end of the valve body 1 is provided with a water inlet, and the other end of the valve body 1 is provided with a water outlet. As the service time increases, impurities carried by various flow media will accumulate in the valve body 1 and cause blockage. In order to solve this problem, the inner side of the valve body 1 near the water inlet end is threadedly connected to an inner filter sleeve 2, and a stainless steel filter screen 3 is fixedly connected to the inner side of the inner filter sleeve 2. The stainless steel filter screen 3 blocks impurities and has rust and corrosion resistance.

[0031] In order to limit the position of the inner filter sleeve 2 and prevent the inner filter sleeve 2 from being separated from the valve body 1 during long-term use, an internal ring seat 5 is provided at one end of the inner filter sleeve 2 and located inside the valve body 1. The internal ring seat 5 is fixedly connected to the valve body 1. An annular groove 4 is provided on the outer side of the inner filter sleeve 2 near one end of the internal ring seat 5. A limiting component is provided inside the internal ring seat 5 and outside the annular groove 4.

[0032] Specifically, the limiting assembly includes a hollow barrel 7, an inner side of a built-in ring seat 5 and located on the outer side of the inner filter sleeve 2, and four hollow barrels 7 are rotatably connected in an array. A limiting support block 8 is fixed on the outer side of each hollow barrel 7. When the hollow barrel 7 rotates, it is convenient to drive the limiting support block 8 to flip around the hollow barrel 7 as the axis, so that the end of the limiting support block 8 away from the hollow barrel 7 moves to the inner side of the annular groove 4, and the end of the limiting support block 8 away from the hollow barrel 7 is in contact with the inner side of the annular groove 4, thereby limiting the inner filter sleeve 2.

[0033] In order to facilitate the simultaneous rotation of the four hollow screw barrels 7, an external ring seat 10 is provided on the outer side of the valve body 1 near the water inlet end. The external ring seat 10 is slidably connected to the valve body 1. Four screws 11 are fixed in an array at one end of the external ring seat 10. The ends of the screws 11 away from the external ring seat 10 respectively penetrate the valve body 1 and the internal ring seat 5 and are threadedly connected to the hollow screw barrel 7. The screws 11 are slidably connected to the valve body 1 and the internal ring seat 5.

[0034] When the outer ring seat 10 slides into the outer side of the valve body main body 1 and the screw 11 is inserted into the hollow barrel 7 to drive the hollow barrel 7 to rotate, in order to fix the position of the outer ring seat 10, the end of the outer ring seat 10 away from the screw 11 is rotatably connected to the hand-tightening barrel 12, and the outer side of the hand-tightening barrel 12 is provided with anti-slip grooves. The hand-tightening barrel 12 is threadedly connected to the valve body main body 1, and then the friction between the hand-tightening barrel 12 and the valve body main body 1 is increased by tightening the hand-tightening barrel 12, so that the outer ring seat 10 can be fixed. Since the hand-tightening barrel 12 is located on the outside of the valve body main body 1, the tightening or loosening operation of the hand-tightening barrel 12 is convenient, and the inner filter sleeve 2 is not convenient for tightening operation due to being located inside the valve body main body 1, and then there is no need to tighten the inner filter sleeve 2;

[0035] Example 2:

[0036] The novel four-way booster valve provided in Example 1 is further optimized. Specifically, Figure 5 As shown, when the screw 11 is pulled out from the inside of the hollow barrel 7, in order to prevent the hollow barrel 7 from rotating due to the gravity of the limit support block 8, a spring 9 is fixed to the outside of the four hollow barrels 7. The end of the spring 9 away from the hollow barrel 7 is fixed to the built-in ring seat 5. When the inner filter sleeve 2 is screwed into the valve body 1, in order to limit the stroke of the inner filter sleeve 2 so that the annular groove 4 can be aligned with the limit support block 8, a limit ring 6 is fixed to the inner side of the end of the built-in ring seat 5 away from the inner filter sleeve 2, and the inner filter sleeve 2 fits in place with the limit ring 6.

[0037] The use process of the novel four-way booster valve provided by the utility model is as follows: when installing the inner filter sleeve 2, the inner filter sleeve 2 is screwed into the inner side of the valve body 1 by utilizing the threaded connection between the inner filter sleeve 2 and the valve body 1, thereby allowing the inner filter sleeve 2 to enter the inner side of the valve body 1, and the limiting ring 6 is used to limit the movement stroke of the inner filter sleeve 2, so that when the inner filter sleeve 2 and the limiting ring 6 are in contact with each other, the annular groove 4 can be aligned with the limiting support block 8, and there is no need to tighten the inner filter sleeve 2, thereby avoiding high friction between the inner filter sleeve 2 and the valve body 1, which may cause it to be too firm, thereby making it difficult to disassemble later;

[0038] The outer ring seat 10 is sleeved on the outer side of the valve body main body 1 and the hand-tightening screw barrel 12 is rotated. The threaded connection between the hand-tightening screw barrel 12 and the valve body main body 1 is used to drive the outer ring seat 10 to move in the direction close to the inner ring seat 5, and the rotation connection between the outer ring seat 10 and the hand-tightening screw barrel 12 is used to align the four screws 11 with the four hollow screw barrels 7. As the outer ring seat 10 moves, the screw 11 can smoothly slide through the valve body main body 1 and the inner ring seat 5 and insert into the inner side of the hollow screw barrel 7, thereby driving the hollow screw barrel 7 to rotate, so that the limiting support block 8 moves away from one end of the hollow screw barrel 7 to the inner side of the annular groove 4, thereby limiting the position of the inner filter sleeve 2, preventing the inner filter sleeve 2 from being separated from the valve body main body 1 during long-term use, and increasing the friction between the hand-tightening screw barrel 12 and the valve body main body 1 by tightening the hand-tightening screw barrel 12 to fix the position of the outer ring seat 10.
