Detailed implementation manners

[0025] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0026] Please refer to Figures 1-5 As shown, in this embodiment, a valve performance detection device is provided, including: a base 1, a water tank 2 and a fixing frame 3 are installed on the upper side of the base 1, a linear drive member 4 is installed on the fixing frame 3, the output end of the linear drive member 4 is provided with a detection table 5 located in the water tank 2, two movable plates 6 are slidably fitted on the upper side of the detection table 5, clamping blocks 7 are slidably fitted on both of the two movable plates 6, an inflation assembly 8 cooperating with one of the clamping blocks 7 is installed on the fixing frame 3, wherein, the detection table 5 is of a convex structure, the clamping block 7 is a conical clamping block, a rubber pad is installed on the clamping block 7, and the rubber pad improves the sealing performance between the clamping block 7 and the valve; the linear drive member 4 is an electric telescopic rod or a hydraulic telescopic rod in the prior art;

[0027] An adjustment assembly 11 that cooperates with the clamping blocks 7 is installed on the movable plate 6, a relative movement assembly 10 connected to the two movable plates 6 is installed on the inspection table 5, and a plurality of racks 14 that are in transmission cooperation with the relative movement assembly 10 are installed on one side of the inner wall of the water tank 2.

[0028] One application of this embodiment is as follows: When performing an airtightness test on a valve, first place the valve on the inspection table 5. When starting the linear drive member 4 and the linear drive member 4 drives the inspection table 5 into the water tank 2, the plurality of racks 14 drive the relative movement assembly 10 to operate. The operation of the relative movement assembly 10 can cause the two clamping blocks 7 to clamp the valve on the inspection table 5. At this time, the inflation assembly 8 is used to inflate one of the clamping blocks 7, and the gas is inflated into the valve through the clamping block 7. When bubbles appear in the water tank 2, it indicates that the valve is leaking air and has poor airtightness, and it is classified as a non-conforming product. It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source.

[0029] By providing a plurality of racks 14 in the water tank 2, when the valve is placed on the inspection table 5 and the linear drive member 4 drives the inspection table 5 into the water tank 2, the plurality of racks 14 drive the relative movement assembly 10 to operate, enabling the two clamping blocks 7 to clamp the valve on the inspection table 5, reducing the need for additional clamping operations on the valve, thereby improving the efficiency of valve inspection. By providing the adjustment assembly 11 on the movable plate 6, the distance between the two clamping blocks 7 can be adjusted, facilitating the clamping of valves of different sizes.

[0030] As Figures 3-5 shown, the relative movement assembly 10 of this embodiment includes a channel 1003 opened on the upper side of the inspection table 5, a bidirectional threaded rod 1001 rotatably fitted in the channel 1003, and two threaded blocks 1002 slidably fitted in the channel 1003 and threadedly fitted on the bidirectional threaded rod 1001. The threaded block 1002 is fixedly connected to the bottom of the movable plate 6, and the bidirectional threaded rod 1001 is in transmission cooperation with the plurality of racks 14; a through groove 17 communicating with the channel 1003 is opened on one side of the inspection table 5. A first synchronous pulley 12 is installed at the middle end of the bidirectional threaded rod 1001, and a second synchronous pulley 13 in transmission cooperation with the plurality of racks 14 is rotatably fitted in the through groove 17. A synchronous belt 15 is sleeved between the first synchronous pulley 12 and the second synchronous pulley 13; a gear 16 meshing with the plurality of racks 14 is installed on one side of the second synchronous pulley 13, and the gear 16 is located at the notch of the through groove 17.

[0031] When the linear driving member 4 drives the detection table 5 into the water tank 2, the movement of the detection table 5 drives the gear 16 to engage with a plurality of racks 14 and then rotate. The rotation of the gear 16 drives the second synchronous wheel 13 to rotate. The rotation of the second synchronous wheel 13 drives the first synchronous wheel 12 to rotate through the synchronous belt 15. The rotation of the first synchronous wheel 12 drives the bidirectional threaded rod 1001 to rotate. The rotation of the bidirectional threaded rod 1001 drives the two threaded blocks 1002 to move relatively in the channel 1003. The relative movement of the two threaded blocks 1002 drives the two movable plates 6 to move relatively. The relative movement of the two movable plates 6 drives the two clamping blocks 7 to clamp both ends of the valve on the detection table 5, reducing the need for additional clamping operations on the valve, thereby improving the efficiency of valve detection.

[0032] As shown in FIG. 4, the adjusting assembly 11 of this embodiment includes a sliding plate 1101 slidably fitted on the movable plate 6 and fixedly connected to one side of the clamping block 7, a fixing plate 1102 installed on the movable plate 6, a threaded hole 1103 opened on one side of the fixing plate 1102, and an adjusting bolt 1104 threadedly fitted in the threaded hole 1103. The threaded end of the adjusting bolt 1104 is rotatably fitted on one side of the sliding plate 1101.

[0033] When adjusting the distance between the two clamping blocks 7, rotate the adjusting bolt 1104. The adjusting bolt 1104 screws into or out of the threaded hole 1103 to drive the sliding plate 1101 to move on the movable plate 6. The movement of the sliding plate 1101 drives the clamping block 7 to move, and the distance between the two clamping blocks 7 can be adjusted, so as to facilitate clamping of valves of different sizes.

[0034] As Figure 2 shown, the inflation assembly 8 of this embodiment includes an air pump 802 installed on the upper side of the fixing frame 3, an air pipe 801 connected between the air outlet of the air pump 802 and the clamping block 7, and an air passage opened on one side of the clamping block 7 and communicated with the air pipe 801.

[0035] When performing airtightness detection on the valve, the air pump 802 is started to generate gas, which enters the air passage of the clamping block 7 through the air pipe 801. The gas in the air passage enters the valve. When bubbles appear in the water tank 2, it indicates that the valve leaks air and has poor airtightness, and is classified as a defective product.

Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, all fall within the protection scope of the present invention. The technologies, shapes, and structures not described in detail in the present invention are all well-known technologies.
