[0002] The hydraulic valve test bench is a pressure performance test equipment specially designed for hydraulic valves. It is mainly used to detect the sealing of the valve and the strength of the valve body. The components of the hydraulic valve test bench include the main frame, the horizontal translation working plate and the sealing blind plates corresponding to different valve calibers. These components ensure a comprehensive pressure performance test of the valve, including shell test, upper sealing test and high-pressure water sealing test. During the test, it can be judged by visual observation whether the valve is leaking. If necessary, a flow test module can be added according to actual needs. The power source of the hydraulic valve test bench is usually to provide pressure through the driving air source, and its air pressure range is usually between 0.2 and 0.8 MPa.

DETAILED DESCRIPTION

[0018] 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.

[0020] Embodiment 1:

[0021] In this embodiment, an isolation and temperature measuring mechanism of a hydraulic valve test bench includes a workbench 1, and anti-slip strips 4 are provided at the upper and lower ends of the front side of the workbench 1. The upper and lower ends of the front side of the workbench 1 are fixedly connected to a base 7, and the top and bottom of one side of the base 7 are penetrated by a first bolt 8. A sliding rod 14 is provided inside the base 7, and a slider 11 is slidably connected to the sliding rod 14. A rotating shaft is provided on one side of the top of the slider 11, and a bracket 15 is rotatably connected to the top of the rotating shaft. The bracket 15 is V-shaped, and a telescopic rod 10 is provided on one side of the base 7.

[0022] In this embodiment, a moving block 13 is fixedly connected to one side of the telescopic rod 10 , a bracket 15 is rotatably connected to both sides of the telescopic rod 10 , and a spring 16 is fixedly connected to the gap of the bracket 15 .

[0023] In this embodiment, a clamping block 3 is provided on one side of the moving block 13, and a moving groove is opened on one side of the clamping block 3, which is adapted to the moving block 13. A second bolt 12 passes through one side of the front of the clamping block 3, and the second bolt 12 is threadedly connected to the moving block 13.

[0024] In this embodiment, every two clamping blocks 3 are aligned at 90 degrees to each other, and a fixing rod 9 is rotatably provided on the front side of one of the clamping blocks 3 . A knob is passed through the top of the front side of the fixing rod 9 , and the knob is threadedly connected to the other clamping block 3 .

[0025] When using, the user needs to place the valve on the workbench 1 first. If it is a valve of normal size, align one side of the valve with one side of the clamp block 3 when placing it. After alignment, push the clamp block 3 to one side, and then place the other side of the valve on the clamp block 3 on the other side. After placing it, press downward to make the back of the valve stick to the control board 5. When placing the valve, the clamp block 3 will be squeezed, and the squeezed clamp block 3 will drive the moving block 13 to move to one side. The moving block 13 will squeeze the spring 16 and force the bracket 15 to shrink inward. The bracket 15 will be retracted and move horizontally along the sliding rod 14. At this time, the telescopic rod 10 will also shrink at the same time. After the valve is placed, the eight clamp blocks 3 will automatically position themselves to the center of the workbench 1 through the rebound force of the spring 16 itself. If the size of the valve deviates slightly, the clamp block 3 will automatically move to the center of the workbench 1. The block 3 can also be freely adjusted by loosening the second bolt 12. When squeezed in different directions, the clamping block 3 will make the moving block 13 move along the moving groove. After moving to the appropriate position, re-tightening the second bolt 12 can determine the size of the valve. If the size of the valve to be clamped is too large, for example, the length is too long or the width is too wide, and its size is already greater than the contraction limit of the telescopic rod 10, the base 7 on the side that is too large can be removed. When removing, first determine the position of the clamping block 3 to be removed, and then rotate and loosen the knob after determination. After opening the knob, rotate the fixing rod 9 to separate the two mutually matched clamping blocks 3. After separation, loosen the first bolt 8. After loosening, the base 7 can be removed from the workbench 1. After removal, the valve can continue to be clamped to avoid affecting normal operation.

[0026] Embodiment 2:

[0027] In this embodiment, a control panel 5 is provided at the upper and lower ends of both sides of the front side of the workbench 1, a support plate 20 is provided at the bottom of the control panel 5, a sleeve 19 is provided on the support plate 20, a connecting plate 2 is fixedly connected to the top and bottom of one side of the support plate 20, a thermometer 6 passes through the connecting plate 2, and a pull ring 18 is fixedly connected to one end of the thermometer 6.

[0028] In this embodiment, one end of the thermometer 6 can pass through the sleeve 19 for temperature measurement, and a fixing screw 17 passes through the upper end of the connecting plate 2 , and the fixing screw 17 is used to limit the pull ring 18 to fix the thermometer 6 .

[0029] After the valve is fixed, the temperature of the hydraulic valve experiment can be measured. When temperature measurement is required, the fixing screw 17 is unscrewed and the pull ring 18 is used to drive the thermometer 6 to move the experimental part to measure the temperature. After the temperature measurement is completed, the position of the thermometer 6 is restored and fixed.

[0030] Working principle: the user needs to place the valve on the workbench 1 first when using it. If it is a valve of normal size, align one side of the valve with one side of the clamp block 3 when placing it. After alignment, push the clamp block 3 to one side, and then place the other side of the valve on the clamp block 3 on the other side. After placing it, press downward to make the back of the valve stick to the control panel 5. When placing the valve, the clamp block 3 will be squeezed, and the squeezed clamp block 3 will drive the moving block 13 to move to one side. The moving block 13 will squeeze the spring 16 and force the bracket 15 to shrink inward. The bracket 15 will be retracted and move horizontally along the slide rod 14. At this time, the telescopic rod 10 will also shrink at the same time. After the valve is placed, the eight clamp blocks 3 will be automatically positioned to the center of the workbench 1 through the rebound force of the spring 16 itself. If the size of the valve deviates slightly, the clamp block 3 can also be freely adjusted by loosening the second bolt 12. When squeezed in different directions, the clamp block 3 will The movable block 13 moves along the movable groove, and after moving to the appropriate position, the second bolt 12 is tightened again to determine the size of the valve. If the size of the valve to be clamped is too large, for example, the length is too long or the width is too wide, and its size is already greater than the contraction limit of the telescopic rod 10, the base 7 on the side that is too large can be removed. When removing, first determine the position of the clamping block 3 to be removed, and after determination, rotate and release the knob. After opening the knob, rotate the fixing rod 9 to separate the two mutually cooperating clamping blocks 3. After separation, loosen the first bolt 8. After loosening, the base 7 can be removed from the workbench 1, and the valve can be clamped again after removal to avoid affecting normal operation; after fixing the valve, the temperature of the hydraulic valve experiment can be measured. When temperature measurement is required, unscrew the fixing screw 17 and use the pull ring 18 to drive the thermometer 6 to move the experimental part to measure the temperature. After the temperature measurement is completed, restore the position and fix the position of the thermometer 6.
