Description

Technical Field

[0001] The utility model belongs to the technical field of valve detection tooling, in particular to a regulating valve performance test fixture. Background Art

[0002] Regulating valves undergo rigorous testing and experimentation before leaving the factory, which is crucial for ensuring product quality. The national standard for pneumatic regulating valves, GB / T4213-2008, provides detailed regulations for regulating valve testing. These tests include ten items: packing and other joint seals, air chamber tightness, basic error, hysteresis, deadband, start / stop deviation, and rated stroke deviation. During these tests, regulating valve samples must be secured. The current method involves using the regulating valve's flange to mount the sample on a simulated pipeline, as if it were actually installed. This is time-consuming and labor-intensive, significantly impacting testing efficiency.

[0003] For example, a regulating valve performance test fixture disclosed in patent application number CN202121328896.8 includes a valve body fixed plate, a valve body movable plate and a driving member, wherein the valve body movable plate is opposite to the valve body fixed plate and connected to the driving member. When using this regulating valve performance test fixture, one end flange of the regulating valve sample to be tested is fitted on the valve body fixed plate, the driving member is started, and the valve body movable plate is driven close to the valve body fixed plate, and the valve body movable plate is pressed against the other end flange of the regulating valve sample, thereby clamping the sample; the driving member drives the valve body movable plate away from the valve body fixed plate, and then releases the sample. The utility model fixes the regulating valve sample through the clamping force of the valve body movable plate and the valve body fixed plate, takes less time, has a low proportion of manual labor, is easy to operate, and can improve testing efficiency.

[0004] In the prior art, the flange is tightly attached to the gasket through structures such as the valve body fixed clamping plate and the valve body movable clamping plate, and the other side of the valve body is squeezed, thereby fixing the valve body. When the valve body is fixed, there is no need to manually support the valve body. However, there are still some shortcomings: First, the existing fixing device cannot be adapted according to the different sizes of flanges and the different bolt holes on the flanges, which makes the adaptability of the device poor.

[0005] Moreover, the existing fixing device cannot rotate after fixing the valve body, which causes many inconveniences in operating the valve body during performance testing and seriously affects the progress of the test. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention provides a device for testing and fixing the performance of a regulating valve. By providing a sliding rod and other structures, the device can adaptably engage and fix the flanges of regulating valves of different sizes with threaded fixing holes of flanges of different sizes. Furthermore, by providing a first engaging groove and other structures, the engaging protrusion can engage with the first engaging groove, thereby controlling the rotation of the rotating disk.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Example 1:

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a regulating valve performance test fixture includes a workbench 10, and two side plates 11 are symmetrically provided on the upper end surface of the workbench 10. A slide 12 is slidably provided on one side of each side plate 11. A first push cylinder 35 is provided on one side of the side plate 11. The output end of the first push cylinder 35 passes through the side plate 11 and is fixedly connected to one side of the slide 12. A slip ring 14 is fixedly provided on the slide 12. A rotating disk 15 is rotatably provided inside the slip ring 14. An annular groove 33 is provided on the inner circumferential surface of the slip ring 14. An annular convex is slidably provided inside the annular groove 33. The annular protrusion 34 is fixedly connected to the rotating disk 15. A plurality of first through holes 17 are provided above the rotating disk 15. The plurality of first through holes 17 are annularly distributed according to the pitch of the threaded fixing holes of the flanges of different sizes. A sliding rod 19 is slidably provided inside each first through hole 17. A groove 18 is provided inside each first through hole 17. A spring 20 is provided inside each groove 18 on the outside of the sliding rod 19. A second anti-slip protrusion 21 is provided at one end of each sliding rod 19, and a snap-fit ​​fixing component is provided on one side of the rotating disk 15.

[0030] Specifically, the first push cylinder 35 is an ordinary push cylinder, which is the existing technology. The output end of the first push cylinder 35 can drive the slide 12 to move horizontally, so that the device can clamp and fix regulating valves of different sizes by changing the distance between the two slides 12.

[0031] The provision of the annular groove 33 and the annular protrusion 34 enables the rotating disk 15 to be clamped inside the slip ring 14 , effectively preventing the rotating disk 15 from slipping.

[0032] The spring 20 forms a support for the second anti-slip protrusion 21 through its own elastic tension. When the flange threaded fixing hole of the valve body does not cooperate with the remaining second anti-slip protrusions 21, the flange end face of the valve body will form pressure on one end of the second anti-slip protrusion 21, prompting the second anti-slip protrusion 21 to drive the sliding rod 19 to move into the groove 18. Since the diameter of the second anti-slip protrusion 21 is slightly larger than the diameter of the groove 18, the second anti-slip protrusion 21 will be stuck at the end of the groove 18, forming a support and fixation treatment for the end face of the flange.

[0033] The second anti-slip protrusion 21 is made of elastic material. The setting of the second anti-slip protrusion 21 not only increases the local supporting force of the device on the regulating valve flange, but also effectively prevents the sliding rod 19 from colliding when it is clamped and fixed to the threaded fixing hole on the flange, thereby effectively improving the clamping effect of the device.

[0034] Further, such as Figure 1 and Figure 3 As shown, a support plate 36 is slidably provided between the two rotating disks 15 on the upper end surface of the workbench 10, and a second push cylinder 37 is provided on the lower end surface of the workbench 10. The output end of the second push cylinder 37 passes through the workbench 10 and is fixedly connected to the lower end surface of the support plate 36.

[0035] Specifically, the second push cylinder 37 is an ordinary push cylinder, which is the existing technology. The output end of the second push cylinder 37 drives the support plate 36 to move vertically. The upper end surface of the support plate 36 is placed with the regulating valve to be tested. The output end of the second push cylinder 37 drives the support plate 36 to move upward, so that the regulating valve can be stably moved between the two rotating disks 15, effectively reducing manpower consumption.

[0036] Further, such as Figure 1 and Figure 6 As shown, the clamping and fixing assembly includes a plurality of first clamping grooves 24 arranged on the rotating disk 15, an arc-shaped plate 25 is slidably arranged on one side of the rotating disk 15, a plurality of clamping protrusions 26 are arranged on the arc surface of the arc-shaped plate 25, and the plurality of clamping protrusions 26 are clamped with each other in the first clamping grooves 24, a fixed plate 27 is arranged on the side wall of the slide 12 on one side of the arc-shaped plate 25, a moving rod 28 is slidably arranged inside the fixed plate 27, a handle is provided at one end of the moving rod 28, and one end of the moving rod 28 is fixedly connected to one side wall of the arc-shaped plate 25.

[0037] Specifically, by sliding the movable rod 28, the movable rod 28 drives the arc plate 25, and the arc plate 25 drives multiple snap-fitting protrusions 26 to form a snap-fitting fit with the first snap-fitting groove 24, thereby fixing the rotating disk 15 to prevent the rotating disk 15 from rotating. By controlling the rotation of the rotating disk 15, the rotation of the fixed regulating valve on the control device is effectively controlled, which facilitates the detection of the regulating valve.

[0038] Further, such as Figure 6 and Figure 7 As shown, a plurality of second engaging grooves 30 are provided on the moving rod 28 , a second through hole 29 is provided on the fixing plate 27 , an elastic member 31 is fixedly provided inside the second through hole 29 , and one end of the elastic member 31 is engaged with the inside of the second engaging groove 30 .

[0039] Specifically, the elastic member 31 is fixed inside the second through hole 29, and one end of the elastic member 31 extends into the second clamping groove 30. By pulling the moving rod 28, one end of the elastic member 31 is deformed under the extrusion of the second clamping groove 30, thereby forming resistance to the movement of the moving rod 28, effectively controlling the horizontal sliding of the moving rod 28, and then controlling the clamping and fixing of multiple clamping protrusions 26 to the first clamping groove 24.

[0040] Further, such as Figure 5 As shown, a limiting protective shell 22 is slidably provided inside the groove 18 and outside the spring 20 , and one end of the limiting protective shell 22 is fixedly connected to a side wall of the second anti-slip protrusion 21 .

[0041] Specifically, the outer wall diameter of the limiting protective shell 22 is the same as the inner wall diameter of the groove 18. Through the setting of the limiting protective shell 22, the spring 20 is protected from contacting the flange of the regulating valve installed on the device, and the sliding rod 19 and the spring 20 are limited, so that the sliding and deformation of the sliding rod 19 and the spring 20 inside the groove 18 are smoother.

[0042] Further, such as Figure 3 and Figure 5 As shown, a limiting plate 23 is fixedly provided at one end of each sliding rod 19 on one side of the rotating disk 15 .

[0043] Specifically, the setting of the limiting plate 23 forms a limiting effect on the sliding rod 19 to prevent the sliding rod 19 from slipping out of the first through hole 17 .

[0044] First, place the regulating valve to be tested on the upper end surface of the support plate 36, start the second push cylinder 37, and the output end of the second push cylinder 37 drives the support plate 36 to move vertically upward, and the support plate 36 drives the regulating valve to move upward until the regulating valve moves to the preset position, and then start the two first push cylinders 35, and the output end of the first push cylinder 35 drives the slide 12, the slip ring 14, the rotating disk 15 and other components until the threaded fixing holes on the flanges on both sides of the regulating valve are clamped and fixed by the multiple second anti-slip protrusions 21 and the slide rod 19 and other components on the rotating disk 15. In this process, the slide rod 19 and the second anti-slip protrusion 21 that cannot be adapted to the threaded fixing holes on the flange will be squeezed into the groove 18, and this part of the second anti-slip protrusion 21 will be stuck at the port of the groove 18, forming a multi-point support for the flange, thereby improving the fixing effect of the regulating valve.

[0045] Then, according to the test requirements, the rotating disk 15 is rotated or fixed by clamping, so that the regulating valve can be adjusted in angle, which is convenient for the staff to quickly test.

[0046] Finally, after the test is completed, the second push cylinder 37 is started again, and the output end of the second push cylinder 37 drives the support plate 36 to support the bottom of the regulating valve. When the test is completed, the two second push cylinders 37 are started to release the clamping of the regulating valve.

[0047] Example 2:

[0048] On the basis of the first embodiment, a further embodiment is made, such as Figure 4 As shown, a plurality of first anti-slip protrusions 16 are provided on the end surface of the rotating disk 15 between the plurality of second anti-slip protrusions 21 .

[0049] Specifically, the first anti-slip protrusion 16 is the same size as the second anti-slip protrusion 21, and both are made of elastic material. The setting of the first anti-slip protrusion 16 enables the rotating disk 15 to provide more multi-point local support force when supporting the flange of the regulating valve, thereby effectively improving the fixing effect of the device.
