[0043] Specifically, during implementation, a numerical control electric box 10, a bottom support 20, guide shafts 30, a supporting plate 40, linear bearings 50, fixing rings 60, pressing parts 70 and a driving part 80 are provided; the angle valve 200 to be tested is arranged at the space 100 formed between the supporting plate 40, the guide shafts 30 and the bottom support 20, and is pressed by the pressing part 70. The position of the supporting plate 40 is adjusted, and the supporting plate 40 and the linear bearings 50 slide along the guide shafts 30, so that the driving part 80 is connected to the angle valve 200 to be tested, the fixing ring 60 is locked to position the supporting plate 40, and the driving part 80 is controlled by the numerical control electric box 10 to rotate, and the driving part 80 drives the angle valve 200 to be tested to open and close, realizing the life test of the angle valve 200 to be tested, with relatively high efficiency and reduced manual workload;

[0044] Another implementation mode:

[0045] Such as Figure 1As shown; during implementation, the numerical control electric box 10 is a common structure in the prior art and has a control panel for electrically controlling the operation of the stepping motor 81. The operation is relatively convenient. An ordinary person skilled in the art can directly and unambiguously know how to set it after seeing the disclosed content, without the need to perform creative labor or excessive experiments;

[0046] Another implementation method:

[0047] As Figure 1 、 Figure 2 、 Figure 3 shown; during implementation, the bottom support 20 is a square plate-like structure, forming a reliable support structure;

[0048] Another implementation method:

[0049] As Figure 1 、 Figure 2 、 Figure 3 shown; during implementation, the guide shaft 30 is a section of round shaft, and one end is inserted or welded to the bottom support 20 to form a guide, which is beneficial for the support plate 40 to move along the position, adjust the position of the adapter 83, so that the adapter 83 is inserted or separated from the square groove 201;

[0050] Another implementation method:

[0051] As Figure 1 、 Figure 2 、 Figure 3 shown; during implementation, the support plate 40 is a square plate-like structure and has two first through holes 41 and two second through holes; the first through holes 41 are slidably connected to the guide shaft 30; the second through holes are connected to the linear bearings 50; the support plate 40 can slide along the guide shaft 30 smoothly, so that for different specifications and calibers of the angle valve 200 to be measured, the height position can be freely adjusted by moving the support plate 40 up and down, realizing the insertion of the linkage adapter 83 into the square groove 20, and the flexibility of use is better;

[0052] Another implementation method:

[0053] As Figure 1 、 Figure 2 、 Figure 3 shown; during implementation, the linear bearing 50 is a common structure in the prior art, is inserted at the second through hole, and is connected to the support plate 40 by an internal hexagonal bolt for slidably connecting with the guide shaft 30 to form a guide, making the sliding of the support plate 40 smoother;

[0054] Another implementation method:

[0055] As Figure 1 、 Figure 2 shown;Figure 3 , Figure 4 As shown in Figure 4 ; during implementation, the fixed ring 60 is a common structure in the prior art. After the supporting plate 40 slides along the guiding shaft 30 to a certain position, the adapter 83 is inserted into the square groove 201, and the fixed ring 60 is locked, positioning the supporting plate 40, which is relatively convenient to operate.

[0056] Another implementation mode:

[0057] As Figure 1 , Figure 2 , Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 ; during implementation, the pressing member 70 includes: a pressing plate 71 that contacts one end of the angle valve 200 to be measured; and two second locking bolts 72 that are spaced and connected to the bottom support 20 for pressing down the pressing plate 71.

[0058] The pressing plate 71 is a rectangular plate structure; the second locking bolt 72 is an internal hexagonal bolt that is threadedly connected to the bottom support 20 to press down the pressing plate 71, so that the pressing plate 71 presses the angle valve 200 to be measured, which is relatively convenient to operate.

[0059] Another implementation mode:

[0061] The stepping motor 81 is a common structure in the prior art and is used to generate a rotational driving force to drive the coupling 82 and the adapter 83 to rotate, thereby realizing the opening and closing of the angle valve 200 to be measured.

[0062] The coupling 82 is a common structure in the prior art, such as a threaded coupling, and is used to connect the transmission shaft and the adapter 83.

[0063] The adapter 83 includes: a shaft section connected to the coupling 82; and a square block 83-1 connected to the shaft section and plugged into the square groove 201; the shaft section and the square block 83-1 are integrally formed, and the plugging of the square block 83-1 into the square groove 201 facilitates the stepping motor 81 to link the angle valve 200 to be measured to open and close (for example: the forward rotation of the stepping motor 81 opens the angle valve 200 to be measured, and the reverse rotation closes the angle valve 200 to be measured);

[0064] The length dimension of the square block 83-1 is greater than the length dimension of the shaft section; the width dimension of the square block 83-1 is greater than the outer diameter dimension of the shaft section; the transverse section of the square block 83-1 is a square, and the size control enables the square block 83-1 to be reliably plugged into the square groove 201, and the contact area with the square groove 201 is relatively large, which is conducive to the opening and closing of the adapter 83 in conjunction with the angle valve 200 to be measured;

[0065] Another embodiment:

[0066] like Figure 1 , Figure 2 , Figure 3 As shown; when implemented, it also includes: four stoppers 90, one-to-one connected to the top of the guide shaft 30, for blocking the support plate 40;

[0067] The limiting member 90 includes: a limiting baffle 91 for blocking the supporting plate 40; and a first locking bolt 92 connected to the top of the guide shaft 30 to lock the limiting baffle 91 and the guide shaft 30;

[0068] The limit baffle 91 is a circular plate-shaped structure, and the diameter of the limit baffle 91 is larger than the diameter of the guide shaft 30, forming a barrier to prevent the support plate 40 from disengaging from the guide shaft 30 when the support plate 40 moves along the guide shaft 30;

[0069] The first locking bolt 92 is a hexagon socket bolt, which is threadedly connected to the guide shaft 30 to press the limit baffle 91;

[0070] Regarding the structure of the angle valve 200 being measured:

[0071] See Figure 1 , Figure 5 The angle valve 200 to be tested has a square groove 201, which is plugged into the adapter 83, so that the angle valve 200 to be tested is rotated by the stepper motor 81, simulating the opening and closing process, and realizing the life test of the angle valve 200 to be tested, which is relatively efficient and reduces the manual workload;

[0072] The working principle is as follows: The angle valve 200 to be measured is arranged at the space 100 formed between the supporting plate 40, the guiding shaft 30 and the bottom support 20, and is pressed by the pressed part 70. The position of the supporting plate 40 is adjusted, and the supporting plate 40 and the linear bearing 50 slide along the guiding shaft 30 so that the driving part 80 is connected to the angle valve 200 to be measured. The fixing ring 60 is locked to position the supporting plate 40. The driving part 80 is controlled to rotate by the numerical control electric box 10, and the driving part 80 drives the angle valve 200 to be measured to open and close, realizing the life test of the angle valve 200 to be measured, with relatively high efficiency and reduced manual workload;
