[0002] The variable displacement valve watertightness test refers to the process of testing the watertightness of the variable displacement valve. The variable displacement valve is a valve used to control the flow of fluid media. Its characteristic is that the flow of the fluid can be changed by adjusting the opening of the valve. The watertightness test is to test the sealing performance of the valve to ensure that the valve can effectively prevent the leakage of the fluid when it is closed.

[0003] Traditional variable displacement valves are mostly tested for water tightness by manual water injection. However, the manual water injection process is complicated and labor-intensive due to the size and specifications of the variable displacement valve. At the same time, the operator needs to accurately control the speed and amount of water injection to ensure the accuracy of the test. The overall process is cumbersome. At the same time, it is difficult to stably clamp and position variable displacement valves of different sizes and specifications during water tightness testing. Therefore, a variable displacement valve detection device is proposed to detect the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] Depend on Figure 1-4 A variable displacement valve detection device is provided, comprising a frame 1; two cross beam plates 11 are mounted on the upper end surface of the frame 1, a bracket plate 12 is mounted between the two cross beam plates 11, and a lifting assembly 2 is mounted on the bracket plate 12;

[0024] The lifting assembly 2 includes a screw rod 22 rotatably arranged on the bracket plate 12, a sliding shaft plate 23 is meshed with the outside of the screw rod 22, a pump 3 is mounted on the sliding shaft plate 23, and a water injection pipe 31 is connected to the output end of the pump 3;

[0025] The frame 1 is also equipped with a water receiving box 6 , in which a bearing platform 7 is supported, on which a clamping assembly 8 is provided, and on which a variable displacement valve body 9 is clamped.

[0026] In this embodiment, the clamping assembly 8 provided can provide a stable clamping force for the variable displacement valve body 9, ensuring that the variable displacement valve body 9 maintains a fixed position and posture during the test, which helps to reduce test errors and improve the accuracy and repeatability of the test. At the same time, the overall structure is easy to adjust.

[0027] Furthermore, compared with traditional manual water injection detection, the detection equipment of the present application can realize an automated watertightness detection process; by controlling the lifting speed of the lifting component 2 and the water flow rate of the pump 3, precise water flow control can be achieved, thereby improving the accuracy and repeatability of the test. At this time, the operator only needs to set the relevant parameters and then observe the test results, reducing the tediousness of manual operation. At the same time, the lifting component 2 set can adjust the injection height of the pump 3 according to the height of the variable displacement valve body 9, thereby adapting to variable displacement valve bodies 9 of different sizes. By controlling the lifting distance of the pump 3, it can be ensured that the valves involved in the watertightness test can be fully covered.

[0028] Specifically, refer to Figure 1-2 The lifting assembly 2 also includes a reciprocating motor 21 arranged on the bracket plate 12. The output end of the reciprocating motor 21 passes through the bracket plate 12 and is connected to the screw rod 22. The bracket plate 12 is also equipped with a bearing member, which is rotatably connected to the output end of the reciprocating motor 21. Both ends of the bracket plate 12 are also equipped with side rods 24, which are respectively arranged on one side of the sliding shaft plate 23 and pass through the sliding shaft plate 23.

[0029] In this embodiment, in actual use, the two side rods 24 provided on the bracket plate 12 can be used to limit the sliding shaft plate 23. Figure 2 As shown in , the slide shaft plate 23 is arranged in a T-shape as a whole, and the side rods 24 are arranged on one side of the protruding end of the slide shaft plate 23;

[0030] When the reciprocating motor 21 is connected to the power supply and driven, the reciprocating motor 21 set at this time can drive the screw rod 22 to rotate. When the screw rod 22 is rotating, it is limited by the side rod 24, so that the set sliding shaft plate 23 can move in a straight line within the stroke range of the screw rod 22, thereby driving the pump 3 to move up and down in a straight line; the user can ensure the stability and consistency of the water flow during the test by controlling the pump flow rate of the pump 3 and the lifting speed of the sliding shaft plate 23, thereby ensuring the water tightness detection of variable displacement valve bodies 9 of different sizes.

[0031] Specifically, refer to Figure 1-2 A water bucket 4 is also mounted on the frame 1 , and a conduit 5 is connected to the water bucket 4 , and the other end of the conduit 5 is connected to the input end of the pump 3 .

[0032] In this embodiment, in the actual watertightness operation, the user connects the pump 3 to a power source so that the input end of the pump 3 can drive the conduit 5 to extract the water source in the water bucket 4, and then pump it into the variable displacement valve body 9 through the water injection pipe 31. At this time, the watertightness of the variable displacement valve body 9 can be tested.

[0033] Specifically, refer to Figure 1-3 The supporting platform 7 is a rectangular box structure with an opening at the top. A water outlet is provided at the bottom of the supporting platform 7, and a closing plug is provided at the water outlet.

[0034] In this embodiment, when conducting a water tightness test, if there is a problem with the air tightness of the variable displacement valve body 9, the test water source injected into the variable displacement valve body 9 will leak. At this time, through the supporting setting of the supporting platform 7, the water source leaked through the variable displacement valve body 9 can flow into the supporting platform 7 for collection, thereby avoiding damage to the testing environment. At the same time, the water outlet arranged at the bottom of the supporting platform 7 can be used to discharge and collect the test water, and the closing plug arranged on the supporting platform 7 can be used to close and adjust the supporting platform 7.

[0035] Specifically, refer to Figure 3-4 The clamping assembly 8 includes a pillar 81 arranged on the supporting platform 7, and a clamping seat 82 is assembled on the pillar 81. The clamping seat 82 is rectangular and has a cross-shaped slide groove. Four clamping plates 83 are slidably arranged in the cross-shaped slide groove. The four clamping plates 83 are all U-shaped and the variable displacement valve body 9 is arranged between the four clamping plates 83.

[0036] In this embodiment, in actual use, the clamping assembly 8 can be used to clamp the variable displacement valve body 9. The four clamping plates 83 can improve the safety of clamping detection when tightly clamping the variable displacement valve body 9. The clamping of the variable displacement valve body 9 by the four clamping plates 83 can prevent the valve from moving or falling off during the test, reducing the risk of injury to the operator.

[0037] Specifically, refer to Figure 3-4 Four threaded holes are formed at the bottom of the clamping seat 82 , and a positioning bolt 84 is threadedly connected in each threaded hole. The end of the positioning bolt 84 passes through the support column 81 and abuts against one of the adjacent clamping plates 83 .

[0038] In this embodiment, the user loosens the adjustment positioning bolt 84, and the four clamping plates 83 slidingly set on the pillar 81 can slide. The user adjusts the clamping plates 83 to slide until the four clamping plates 83 press against the side walls of the variable displacement valve body 9, thereby achieving the clamping and positioning of the variable displacement valve body 9. Similarly, when the clamping plates 83 complete the clamping of the variable displacement valve body 9, the user tightens the positioning bolt 84 again, and the four clamping plates 83 complete the clamping and positioning of the variable displacement valve body 9. In a preferred embodiment, in order to improve the clamping stability of the clamping plates 83 on the variable displacement valve body 9, the clamping plates 83 can be metal structures.

[0039] The variable displacement valve detection equipment of the utility model:

[0040] Step 1: When the user performs a water tightness test on the variable displacement valve body 9, the user first places the variable displacement valve body 9 between the four clamping plates 83. At this time, the user loosens the positioning bolts 84 so that the clamping plates 83 can slide in the slide grooves of the pillars 81. The user adjusts the clamping plates 83 to slide until the four clamping plates 83 press against the side walls of the variable displacement valve body 9. Then, the positioning bolts 84 are tightened again, so that the four clamping plates 83 can complete the clamping and positioning of the variable displacement valve body 9.

[0041] Step 2: After the variable displacement valve body 9 is clamped on the clamping assembly 8, the user connects the power supply to the reciprocating motor 21 and controls the reciprocating motor 21 to rotate. When the reciprocating motor 21 is driven, the screw rod 22 connected to the output end of the reciprocating motor 21 will rotate accordingly. At this time, the side rod 24 limits the two sides of the sliding shaft plate 23, so that the sliding shaft plate 23 arranged outside the screw rod 22 will drive the pump 3 to move linearly along the stroke range of the screw rod 22 as a whole; at this time, the user controls the pump 3 to move downward until the end of the water injection pipe 31 extends into the variable displacement valve body 9;

[0042] Step 3: When the water injection pipe 31 enters into the variable displacement valve body 9, the user connects the power supply to the pump 3 so that the input end of the pump 3 can drive the conduit 5 to extract the water in the bucket 4, and then pump it into the variable displacement valve body 9 through the water injection pipe 31. At this time, the water tightness test of the variable displacement valve body 9 can be completed.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
