Technical Field
[0001] The utility model relates to the technical field of test benches, in particular to a submerged hydraulic valve test bench with a waterproof structure. Background Art
[0002] The submersible hydraulic test bench is an ideal device for testing valve housing strength, sealing surface sealing performance, reverse closing seal and airtight seal on the sealing surface. It adopts the method of clamping the flange with jaws, without any additional external force on the valve body. It can test the performance of different valves in different specifications and is specially used for testing various flange valves, such as gate valves, ball valves, stop valves, check valves, etc.
[0003] In the existing technology, there are many types of valves, generally including flange-connected valves, welded-connected valves, etc., and the valve specifications are also different. Generally, the structures of the corresponding test benches are also different. Test benches suitable for small sizes are generally not used to test large-sized valves. In this way, multiple test benches are required to complete the test. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-5 The utility model discloses a submersible hydraulic valve test bench with a waterproof structure, comprising a test bench body 1 and a valve body 2. Two docking flanges 3 are symmetrically provided at both ends of the valve body 2. Two clamping assemblies for clamping the valve body 2 are symmetrically provided on the test bench body 1.
[0027] The clamping assembly includes a telescopic cylinder 5, a motor 6 and a clamping plate 15. The output end of the telescopic cylinder 5 is provided with a base plate 4 that slides with the test bench main body 1. The motor 6 and the clamping plate 15 are fixed above the base plate 4 through a support rod. The output end of the motor 6 is provided with a driving disk 7. The circumferential side of the driving disk 7 is provided with a plurality of arc-shaped driving rods 8. The circumferential side of the clamping plate 15 is provided with a plurality of first slide grooves 11 and a support rod 9. The bottom of the support rod 9 is provided with a first slider 10 and a driven block 14. The driven block 14 contacts the arc-shaped driving rod 8. The first slider 10 slides with the first slide groove 11. The top of the first slide groove 11 is fixedly provided with a positioning seat 12. A cavity is provided inside the positioning seat 12. A first spring is provided inside the cavity. The lower end of the first spring is provided with a positioning block 13 connected to the first slider 10. The top of the support rod 9 is provided with a clamping block that contacts the circumferential side of the docking flange 3.
[0028] An annular groove is provided on the circumference of the clamping plate 15. A plurality of second springs 17 are provided inside the annular groove. A sealing ring 16 is provided on the upper end of the second spring 17 to contact the docking flange 3. The clamping plate 15 can clamp the docking flange 3.
[0029] In this embodiment, the valve body 2 is placed on the test bench body 1, and the telescopic cylinder 5 is started, so that the two clamping plates 15 can contact the docking flange 3. At this time, the sealing ring 16 will contact the docking flange 3, and the sealing ring 16 will compress the second spring 17. At this time, the sealing ring 16 will enter the interior of the annular groove, thereby making the clamping plate 15 more flat.

At this time, the arc-shaped driving rod 8 can drive the driven block 14 to move downward, thereby making the first slider 10 slide downward in the first slide groove 11. At this time, the first slider 10 will stretch the first spring inside the cavity. At this time, the multiple clamping blocks will contact the peripheral side of the docking flange 3, which can improve the stability of the clamping plate 15 when clamping the docking flange 3. When the driving disk 7 rotates in the opposite direction, the spring is gradually reset, thereby making the first slider 10 rise in the first slide groove 11, thereby making the multiple clamping blocks in an open state on the peripheral side of the clamping plate 15, enabling the clamping assembly to clamp docking flanges 3 of different sizes, thereby clamping valve bodies 2 of different sizes, and having low limitations during use.
[0031] In this embodiment, a plurality of second slide grooves are provided on the test bench body 1, and a second slider cooperating with the second slide groove is provided at the lower end of the base plate 4.
