[0001] This utility model relates to the field of valve technology, and in particular to a valve testing device. Background Technology
[0002] A valve is a device used in a fluid system to control the direction, pressure, and flow rate of a fluid. It is a device that allows the medium (liquid, gas, powder) in piping and equipment to flow or stop and controls its flow rate.
[0003] An existing valve testing device places the entire test circuit (including the device, connectors, and the valve itself) under extremely high pressure when testing the strength of a valve. Valves that fail to meet strength standards will shatter, and valve fragments will fly everywhere, potentially causing catastrophic accidents and posing a serious threat to the personal safety of operators. Furthermore, the fragments of a defective valve will fly everywhere inside the device, making cleanup time-consuming and labor-intensive, increasing the workload of workers and affecting their work efficiency. Utility Model Content

[0014] By adopting the above technical solution, the connecting plate can easily drive the clamping plate to clamp the valve, preventing the valve from shifting position during testing.
[0015] A further feature of this invention is that a slide rail is fixedly connected to the top of the sliding plate, and the slide rail is slidably connected to the interior of the connecting plate.
[0016] By adopting the above technical solution, it is easy to restrict the sliding trajectory of the connecting plate by the slide rail, so that the sliding of the connecting plate is kept on the same straight line.
[0017] A further feature of this invention is that a synchronizing rod is fixedly connected to the inner wall of the testing platform, the synchronizing rod is slidably connected to the interior of the sliding plate, and the interior of the sliding plate has a strip-shaped hole.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0030] A valve testing device includes a testing platform 1, a sliding plate 2 slidably connected inside the testing platform 1, a clamping assembly 3 fixedly connected inside the sliding plate 2, a cylinder 4 fixedly connected to the top of the testing platform 1, a pressure plate 5 fixedly connected to the output end of the cylinder 4, a first protective cover 6 connected to the top hinge of the testing platform 1, a second protective cover 7 connected to the top hinge of the testing platform 1, an opening and closing door 8 that engages with the interior of the testing platform 1 connected to the outer hinge of the testing platform 1, a first motor 9 fixedly connected to the outer side of the testing platform 1, a first reciprocating screw 10 rotatably connected to the interior of the testing platform 1 fixedly connected to the output shaft of the first motor 9, and a push plate 11 threadedly connected to the outer side of the first reciprocating screw 10.
[0031] First, by opening the opening and closing door 8, the valve to be tested is placed inside the clamping assembly 3 and fixed. Then, the opening and closing door 8, the first protective cover 6, and the second protective cover 7 are closed. Subsequently, the sliding plate 2 drives the valve to move to the lower side of the cylinder 4. The cylinder 4 is started, and the cylinder 4 drives the pressure plate 5 to move downward, pressurizing the top of the valve. By setting a certain pressure value on the control panel on the left, qualified valves show no abnormalities on their surface, while unqualified valves show cracks or are directly broken into small pieces. By starting the first motor 9, the first motor 9 drives the first reciprocating screw 10 to rotate. Then, the push plate 11 slides towards the end of the opening and closing door 8, thereby pushing the fragments that have fallen inside the testing table 1 to the end of the opening and closing door 8. The opening and closing door 8 is then opened, thereby allowing the fragments to be processed centrally.
[0032] Specifically, refer to Figure 1 The first protective cover 6 and the second protective cover 7 are located on both sides of the cylinder 4. An observation window 12 is provided inside the opening and closing door 8. The observation window 12 is made of transparent explosion-proof glass.
[0033] In a specific implementation, closing the first protective cover 6 and the second protective cover 7 prevents fragments from flying everywhere and causing injury to workers, while the observation window 12 facilitates observation of the valve testing status inside the testing station 1.
[0034] Specifically, refer to Figure 3 The top of the push plate 11 is inclined, and the outer side of the push plate 11 is in contact with the inner wall of the detection table 1.
[0035] In a specific embodiment, the top of the push plate 11 is inclined to prevent debris from accumulating on its top. The push plate 11 is slidably connected to the inner wall of the detection table 1 to prevent the push plate 11 from rotating as the first reciprocating screw 10 rotates.
[0036] Specifically, refer to Figure 2 and Figure 6 A second motor 13 is fixedly connected to the outer side of the testing table 1. The output shaft of the second motor 13 is fixedly connected to a second reciprocating lead screw 14. The outer side of the second reciprocating lead screw 14 is threadedly connected to the inner side of the sliding plate 2.
[0037] In a specific implementation, the second motor 13 is started, which drives the second reciprocating screw 14 to rotate, thereby causing the sliding plate 2 to slide on the inner wall of the detection table 1, so that it slides to the bottom of the cylinder 4, which facilitates the detection of the valve.
[0038] Specifically, refer to Figure 3 , Figure 4 and Figure 5 The clamping assembly 3 includes a support frame 15 fixedly connected to the sliding plate 2. A rotating column 16 is rotatably connected inside the sliding plate 2. A rotating disk 17 is fixedly connected to the outside of the rotating column 16. A sliding groove 18 is opened inside the rotating disk 17. A sliding column 19 is slidably connected inside the sliding groove 18. A connecting plate 20 is fixedly connected to the bottom of the sliding column 19. A clamping plate 21 is fixedly connected to the top of the connecting plate 20.
[0039] In a specific embodiment, the rotating column 16 rotates, causing the rotating disk 17 to rotate counterclockwise, the sliding groove 18 rotates, causing the sliding column 19 to slide, and then the sliding column 19 causes the connecting plate 20 to slide towards the end close to the rotating disk 17, and the connecting plate 20 causes the clamping plate 21 to clamp the valve.
[0040] Specifically, refer to Figure 5 A gear 22 is fixedly connected to the outer side of the rotating column 16, and an electric push rod 23 is fixedly connected to the bottom of the sliding plate 2. A rack 27 that meshes with the gear 22 is fixedly connected to the output end of the electric push rod 23, and the rack 27 is slidably connected to the inside of the sliding plate 2.
[0041] In a specific implementation, the valve is placed on top of the support frame 15, and the electric push rod 23 is activated. The electric push rod 23 retracts and drives the rack 27 to slide, thereby driving the gear 22 to rotate counterclockwise. Then, the rotating column 16 rotates and drives the rotating disk 17 to rotate counterclockwise. The sliding groove 18 rotates and drives the sliding column 19 to slide. Then, the sliding column 19 drives the connecting plate 20 to slide closer to the rotating disk 17. The connecting plate 20 drives the clamping plate 21 to clamp the valve.
[0042] Specifically, refer to Figure 3 The top of the sliding plate 2 is fixedly connected to a slide rail, which is slidably connected to the inside of the connecting plate 20.
[0043] In a specific implementation, the connecting plate 20 slides on the outside of the slide rail, and the slide rail restricts the sliding trajectory of the connecting plate 20 so that it slides on the same straight line.
[0044] Specifically, refer to Figure 3 The inner wall of the testing platform 1 is fixedly connected to a synchronizing rod 24, which is slidably connected to the inside of the sliding plate 2. The inside of the sliding plate 2 is provided with a strip-shaped hole 28.
[0045] In a specific implementation, the synchronizing rod 24 limits and supports the sliding of the sliding plate 2, preventing the sliding plate 2 from rotating as the second reciprocating screw 14 rotates.
[0046] Specifically, refer to Figure 1 and Figure 6 The outer side of the second reciprocating lead screw 14 is fitted with a telescopic sleeve 25 that is fixedly connected to the outer side of the sliding plate 2, and the top of the testing table 1 is fixedly connected with a knob 26.
[0047] In a specific implementation, the telescopic sleeve 25 prevents debris generated by valve breakage from entering the interior of the second reciprocating screw 14 and affecting its normal operation. The valve's fixing, movement, detection, and debris pushing are controlled by the left-side control console and knob 26.
[0048] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

[0049] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
