Description

TECHNICAL FIELD

[0001] The utility model relates to a guide trough structure technical field, concretely is a diaphragm booster pump control body overflow hole guide trough structure. BACKGROUND

[0002] The diaphragm booster pump control body overflow hole is a key component of the diaphragm booster pump, which is located on the control body. Its main function is to allow fluid to pass through. The control body plays an important role in regulating and controlling the fluid flow path in the diaphragm booster pump. The overflow hole is a channel for fluid to enter and exit the control body or flow between different chambers inside the control body. The diaphragm booster pump is mainly used in the field of water purification, serving as a pre-membrane booster. With the increasing demand of the market and customers, high flow rate, low noise, and other requirements are becoming more and more important.

[0003] The existing overflow hole is circular or oval in shape. The inner wall of the overflow hole is in a straight state with the inner wall of the diaphragm booster pump control body, i.e., the overflow hole is a straight hole. When the fluid enters the interior of the overflow hole, the flow direction of the fluid does not change, resulting in no buffering of the fluid speed. When the high-speed flowing fluid comes into contact with the inner wall of the overflow hole or other obstacles, it will generate vortex due to collision, affecting the stable delivery of the fluid. Moreover, in the straight hole, the fluid passing through the interior of the hole will generate a higher pressure peak in some local areas. At this time, the pressure is relatively concentrated, causing damage to the structure of the overflow hole, thereby affecting the performance of the diaphragm booster pump. To address the shortcomings of the prior art, we propose a diaphragm booster pump control body overflow hole guide trough structure to solve the above problems. SUMMARY

[0004] To address the shortcomings of the prior art, the utility model provides a diaphragm booster pump control body overflow hole guide trough structure, which solves the problem of the straight hole shape of the overflow hole. When the fluid enters the interior of the overflow hole, the fluid comes into contact with the inner wall of the overflow hole or other obstacles, generating vortex due to collision. Moreover, when the fluid passes through the interior of the hole, it generates a higher pressure peak in some local areas. At this time, the pressure is relatively concentrated, causing damage to the structure of the overflow hole, thereby affecting the performance of the diaphragm booster pump.

[0005] To achieve the above purpose, the utility model is implemented by the following technical solutions: a diaphragm booster pump control body overflow hole guide trough structure, comprising a first overflow hole and a second overflow hole opened on the surface of the control body, a group of inclined guide troughs are opened on the inner wall of the control body near the first overflow hole and the second overflow hole, and the multiple groups of inclined guide troughs are respectively communicated with the first overflow hole and the second overflow hole. The inclination direction of the inclined guide trough corresponds to the water flow direction.

[0006] Preferably, a first mounting hole is opened on the surface of the control body near the first overflow hole, and a discharge valve is fitted inside the first mounting hole.

[0007] Preferably, the surface of the control body body near the second flow hole is provided with a second mounting hole, and a suction valve is matched and arranged in the second mounting hole.

[0008] Preferably, the side of the control body body near the first mounting hole is provided with an O-shaped ring for tightly connecting the discharge valve and the first mounting hole.

[0009] Preferably, one side of the control body body is provided with a sealing groove for arranging the O-shaped ring.

[0010] The utility model discloses a diaphragm booster pump control body flow hole flow guide groove structure, which has the following beneficial effects: the diaphragm booster pump control body flow hole flow guide groove structure increases the large oblique angle flow guide groove structure at the cooperation place of the diaphragm booster pump pump head control body flow hole, suction valve and discharge valve, so that the fluid can flow out along the large oblique angle flow guide groove when the suction valve and the discharge valve are opened. The structure can change the flow of the fluid, reduce the generation of turbulent flow, and because the large oblique angle flow guide groove is not a vertical channel, impurities are more easily carried out of the flow hole under the double action of gravity and fluid impact force, thereby reducing the blockage inside the large oblique angle flow guide groove, making the fluid flow path unobstructed, thereby improving the water pumping efficiency and self-priming performance of the booster pump and reducing the noise of the booster pump.

[0019] The embodiment of the application provides a diaphragm booster pump control body flow hole guide groove structure, solves the problem that when fluid enters the inside of the flow hole, the fluid collides with the inner wall of the flow hole or other obstacles to generate vortex, and when the fluid passes through the inside, a higher pressure peak is generated in some local areas, at this time, the pressure is more concentrated, so that the flow hole structure is damaged, thereby affecting the performance of the diaphragm booster pump, a large inclined angle guide groove structure is arranged on the inner wall of the flow hole, so that the fluid flow path is not hindered, thereby improving the water pumping efficiency and self-priming performance of the booster pump and reducing the noise of the booster pump.

[0020] In order to better understand the above technical scheme, the above technical scheme will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0021] The embodiment of the utility model discloses a diaphragm booster pump control body flow hole guide groove structure.

[0022] According to the drawings Figures 1-5 As shown, the first flow hole 2 and the second flow hole 3 are arranged on the surface of the control body body 1, the first flow hole 2 and the second flow hole 3 are straight holes, the first mounting hole 21 is arranged on the surface of the control body body 1 close to the first flow hole 2, the discharge valve 4 is arranged in the first mounting hole 21, and the structure of the discharge valve 4 after being mounted in cooperation with the control body body 1 is specifically referred to the drawings Figure 4 , and the structure of the first flow hole 2 after being cooperated is specifically referred to the drawings Figure 4 , the fluid flow direction at the first flow hole 2 is consistent with the arrow direction in the drawings Figure 4 , the second mounting hole 31 is arranged on the surface of the control body body 1 close to the second flow hole 3, the suction valve 5 is arranged in the second mounting hole 31, and the structure of the suction valve 5 after being mounted in cooperation with the control body body 1 is specifically referred to the drawings Figure 4 , and the structure of the first flow hole 2 after being cooperated is specifically referred to the drawings Figure 5, the fluid flow direction at the second flow hole 3 is opposite to the direction of the arrow, after the discharge valve 4 and the suction valve 5 are opened, the fluid can flow in different pipes through the first flow hole 2 and the second flow hole 3. Figure 4 The arrow indicates the same direction, after the discharge valve 4 and the suction valve 5 are opened, the fluid can flow in different pipes through the first flow hole 2 and the second flow hole 3.

[0023] Referring to the accompanying drawings Figures 1-2 The control body 1 is provided with an O-ring 6 for the discharge valve 4 to be closely connected with the first mounting hole 21 on the side close to the first mounting hole 21, and a sealing groove 11 is arranged on one side of the control body 1 for the O-ring 6.

[0024] Referring to the accompanying drawings Figures 4-5 The control body 1 is provided with a group of inclined flow guide grooves 7 on the inner wall close to the first flow hole 2 and the second flow hole 3, and the groups of inclined flow guide grooves 7 are respectively connected with the first flow hole 2 and the second flow hole 3, and the inclined directions of the groups of inclined flow guide grooves 7 correspond to the water flow directions at different positions of the control body 1, when the fluid passes through the inclined flow guide grooves 7, compared with the straight hole, the inclined flow guide grooves 7 can guide the fluid to change the flow direction more smoothly, make the fluid gradually turn, reduce the sudden change of direction, thereby reduce the generation of turbulence, and the inclined flow guide grooves 7 can make the fluid more evenly distributed on the cross section of the group of flow holes, so that the fluid is dispersed, and the flow rate of the fluid in the whole flow area is closer, which helps to improve the working efficiency of the diaphragm booster pump as a whole, and can effectively reduce the noise, for example, the uniform flow rate can ensure that the gas is stably boosted and delivered, avoiding the situation that the local pressure is too high or too low;

[0025] The structure of the inclined flow guide groove 7 is beneficial to prevent solid particles or impurities from accumulating and blocking in the flow hole, if impurities enter the flow hole, due to the inclined groove is not a vertical channel, the impurities are more easily carried out of the flow hole under the double action of gravity and fluid impact force, for some viscous substances or substances that are easy to precipitate, the inclined groove can also reduce their deposition in the flow hole, because the inclined flow guide groove 7 changes the flow path and state of the fluid, so that these substances are not easy to be stationary and deposited in the group of flow holes;

[0026] The oblique guide groove 7 can help to disperse the pressure, in the straight hole shape of the multiple groups of flow holes, the fluid can produce higher pressure peak in some local area when passing through, which can cause damage to the structure of the multiple groups of flow holes, and also can affect the performance of the pump, the oblique guide groove 7 can guide the fluid to disperse the pressure in a wider area, so that the pressure distribution is more uniform, for example, in the high-pressure diaphragm booster pump, the oblique guide groove 7 can more reasonably distribute the pressure of the high-pressure fluid on the structure around the flow hole, prolong the service life of the flow hole, after the fluid passes through the oblique guide groove 7, due to the optimized flow state, the pressure recovery ability after leaving the multiple groups of flow holes is also enhanced, so that the pressure of the fluid after passing through the booster pump control body 1 can be better kept at the required level, which is beneficial to the subsequent transportation and use.
