Water inlet valve flow stabilizer

Abstract

The utility model discloses a water inlet valve current stabilizer which is inserted in a water inlet channel of a water inlet valve for use and comprises a first main body, a plurality of flow dividing ribs distributed at intervals in the direction of the water inlet channel are arranged on the front face of the first main body, and a plurality of flow dividing ribs distributed at intervals in the direction of the water inlet channel are also arranged on the back face of the first main body. Outer side notches are formed between the two ends of the flow dividing ribs and the side edges of the first main body respectively. In the water inlet process of the water inlet valve, water flow is divided into different small water flows under the blocking effect of the flow dividing ribs, the small water flows collide with one another, and the small water flows collide with the side wall of the water inlet channel back and forth, so that the energy of the falling water flow is effectively reduced, and the flow stabilizing effect is achieved. Similarly, after the water inlet valve stops water, the flow dividing ribs block the backflow water flow and divide the backflow water flow into different small water flows, and after the small water flows collide with one another and collide with the side wall of the water inlet channel, energy is consumed, the water path pressure is remarkably reduced, and the water hammer effect is effectively prevented.

Description

Technical Field

[0001] This utility model relates to a flow stabilizer, and more particularly to a water inlet valve flow stabilizer. Background Technology

[0002] To reduce or eliminate the impact and noise caused by the rapid water flow during the water intake process, a flow stabilizer is usually installed in the water intake pipe of the water inlet valve. The conventional flow stabilizer mainly cuts off the flow in the pipe and reduces the impact of the water flow by reducing the flow rate. Although it can reduce the impact and noise of the water flow during the water intake process, the sudden increase in water pressure at the moment the water inlet valve stops the flow can easily generate water hammer effect, which will bring vibration and vibration noise. The conventional flow stabilizer cannot effectively deal with the water hammer effect. Utility Model Content

[0003] This utility model provides an inlet valve flow stabilizer, which overcomes the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:

[0004] The inlet valve flow stabilizer is inserted into the inlet channel of the inlet valve for use. It includes a main body. The front of the main body is provided with a number of diverting ribs that are spaced apart along the direction of the inlet channel. The back of the main body is also provided with a number of diverting ribs that are spaced apart along the direction of the inlet channel. The two ends of the diverting ribs form an outer notch between them and the side of the main body.

[0005] In a preferred embodiment: the diversion rib is V-shaped, with its tip facing the water inlet side of the water inlet channel and its opening facing the water outlet side of the water inlet channel.

[0006] In a preferred embodiment: the front of the main body is provided with a plurality of converging ribs spaced apart along the water inlet channel direction, and the back of the main body is also provided with a plurality of converging ribs spaced apart along the water inlet channel direction. The converging ribs and the diverting ribs are arranged alternately. The converging ribs are in the shape of an "eight", with both ends extending outward to the side of the main body, and an inner notch formed in the middle.

[0007] In a preferred embodiment, the inner notch of the confluence rib faces the water inlet side of the water inlet channel.

[0008] In a preferred embodiment: the front and back of the main body are respectively provided with cutting ribs at the middle position, and the cutting ribs are located on the side of all the confluence ribs and diversion ribs facing the water outlet direction of the water inlet channel.

[0009] In a preferred embodiment, the height of the diversion rib extends to the side wall of the water inlet channel.

[0010] In a preferred embodiment: the height of the confluence rib gradually increases from the outside to the inside, and the side height of the inner notch of the confluence rib extends to the side wall of the water inlet channel.

[0011] In a preferred embodiment, the system further includes a second main body, which is integrally formed with the first main body. The front and back sides of the second main body are respectively provided with filter belts extending along the length direction of the second main body. The height of the filter belts extends to the side wall of the water inlet channel. The two ends of the filter belts are respectively located on the left and right sides of the second main body. The filter belts are provided with a plurality of filter holes at intervals along their length direction.

[0012] In a preferred embodiment: the first body and the second body are plate-like structures on the same surface.

[0013] In a preferred embodiment, the system further includes a third body. The first body, the second body, and the third body are integrally formed. The outer peripheral surface of the third body, which is connected to the second body, is adapted to the side wall of the water inlet channel. The third body is provided with flow-limiting grooves at positions corresponding to the front and back of the second body.

[0014] Compared with the prior art, this technical solution has the following advantages:

[0015] 1. Several diversion ribs are provided on the front and back of the main body. During the water intake process through the inlet valve, the water flow is divided into different smaller water flows by the obstruction of the diversion ribs. These smaller water flows collide with each other and with the side wall of the inlet channel, thereby effectively dissipating the energy of the water flow and achieving a stable flow effect. Similarly, after the inlet valve stops, the water pressure increases and backflow occurs. The diversion ribs also block the backflow and divide the backflow into different smaller water flows. After the smaller water flows collide with each other and with the side wall of the inlet channel, the energy is greatly consumed, and the water pressure drops significantly, thereby effectively preventing the water hammer effect.

[0016] 2. The diversion ribs are V-shaped, which better blocks the backflow of water and makes the diverted small water flow meander, resulting in greater energy consumption of the water flow.

[0017] 3. The confluence and divergence ribs are arranged in an alternating manner. The confluence ribs enable the smaller water flows after divergence to merge and rush towards the divergence ribs, further increasing the detour effect and making the water flow orderly diverge and collide, maximizing the consumption of water flow energy and pressure.

[0018] 4. The height of the diversion rib extends to the side wall of the water inlet channel, that is, the two are adapted to each other to minimize the water flow directly through the blank area between them.

[0019] 5. The filter belts on the front and back of the main body not only perform the filtration function during water intake, but also obstruct the water flow during water intake and water stop, and increase the energy dissipation effect of the collision between water flows.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Figure 2 It is illustrated Figure 1 The diagram shows a side view of the inlet valve flow stabilizer.

[0023] Figure 3 It is illustrated Figure 1 The diagram shows a front view of the inlet valve flow stabilizer.

[0024] Figure 4 It is illustrated Figure 1 The diagram shows the inlet valve flow stabilizer installed in the inlet channel of the inlet valve. Detailed Implementation

[0025] Please refer to Figures 1 to 4 The inlet valve flow stabilizer 100 is inserted into the inlet channel 200 of the inlet valve for use. The flow stabilizer 100 includes a main body 10, and the front and back of the main body 1 are provided with a plurality of diverting ribs 12 distributed at intervals along the direction of the inlet channel. The two ends of the diverting ribs 12 form an outer notch 14 between them and the side of the main body 10. Figure 4 The arrow indicates the direction of water flow during the water inlet valve process. Understandably, once the water inlet valve stops, the water pressure in the water inlet channel 200 increases, which will cause the water in the water inlet valve to flow back or reverse. The direction of water reversal is, of course, opposite to the direction of the arrow.

[0026] During the water intake process at the inlet valve, the water flow is split to the left and right after encountering the diversion ribs 12. Similarly, when the inlet valve stops, the returning water flow is also split to the left and right after encountering the diversion ribs 12. This splitting of the water flow results in a significant loss of momentum due to collisions between the water flows, between the water flow and the side wall of the inlet channel 200, and between the water flow and the diversion ribs 12. This helps to prevent water hammer and, understandably, significantly improves the flow stabilization effect.

[0027] Preferably, the diversion rib 12 is V-shaped, with its tip facing the water inlet side of the water inlet channel 200, i.e. Figure 4 The center faces downwards, while the opening faces the outlet side of the water inlet channel 200, i.e. Figure 4The center is facing upwards. Therefore, when the inlet valve stops the water flow and causes backflow, the diversion ribs can create a backflow effect.

[0028] Preferably, the front and back of the main body 10 are provided with a plurality of converging ribs 16 spaced apart along the direction of the water inlet channel. The converging ribs 16 and the diverting ribs 12 are arranged alternately. The converging ribs 12 are in the shape of a figure eight, with both ends extending outward to the side of the main body and forming an inner notch 18 in the middle. More preferably, the inner notch 18 of the converging ribs 16 faces the water inlet side of the water inlet channel 200, that is, the diverting ribs 12 and the converging ribs 16 face the same direction.

[0029] Preferably, the front and back of the main body 10 are provided with cutting ribs 19 at the middle position, and the cutting ribs 19 are located on the side of all the confluence ribs 12 and the diversion ribs 16 facing the water outlet direction of the water inlet channel 200.

[0030] Preferably, the height of the diversion rib 12 extends to the side wall of the water inlet channel 200. That is, the top surface of the diversion rib is as close as possible to the side wall of the water inlet channel, so that the water collides with the diversion rib as much as possible.

[0031] Preferably, the height of the confluence rib 16 gradually increases from the outside to the inside, and the side height of the inner notch 18 of the confluence rib 16 extends to the side wall of the water inlet channel 200. Thus, a small portion of the water flow will pass between the outer top surface of the confluence rib 16 and the side wall of the water inlet channel 200, increasing the number of diversions and making the collision effect between the water flows more significant.

[0032] Preferably, the system further includes a second main body 20, which is integrally formed with the first main body 10. The front and back of the second main body 20 are respectively provided with filter belts 22 extending along the length direction of the second main body. The height of the filter belts 22 extends to the side wall of the water inlet channel 200. The two ends of the filter belts 22 are located on the left and right sides of the second main body 20, respectively, ensuring that all water flow can pass through the filter belts. The filter belts 22 are provided with a plurality of filter holes 24 at intervals along their length direction. More preferably, the first main body 10 and the second main body 20 are plate-like structures on the same surface.

[0033] Preferably, the system also includes a third main body 30. The first main body 10, the second main body 20, and the third main body 30 are integrally formed. The outer peripheral surface of the end of the third main body 30 connected to the second main body 20 is adapted to fit the side wall of the water inlet channel 200, i.e., it fits as closely as possible. The third main body 30 is provided with flow-limiting grooves 32 at positions corresponding to the front and back of the second main body 20. In this way, after the water flows through the filter belt 22, it is output from the flow-limiting grooves 33. In fact, the flow-limiting grooves on the third main body also achieve the function of interception, similar to the traditional structure.

[0034] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
