Description

Technical Field

[0001] This utility model relates to the field of horizontal valve technology, and in particular to a novel horizontal valve testing bench. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. After the horizontal valve is manufactured, to ensure its normal use, it needs to be placed on a test bench for testing. When testing the valve's sealing performance, the connecting flange of a water pipe is connected to the valve's inlet and outlet pipes, and the valve surface is observed for any overflow. During the testing process, water easily accumulates on the test bench, making water collection difficult and causing excessive water buildup, affecting subsequent operations. Furthermore, during valve testing, valve limiters are required. Common limiters are prone to loosening when the valve shakes, affecting valve stability. Therefore, we propose a novel horizontal valve test bench. Utility Model Content

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figures 1-4 As shown, this utility model is a novel horizontal valve testing bench, including a bench body 1. A clamping box 2 is provided at the upper end of the bench body 1. A screw 21 is movably mounted inside the clamping box 2 via bearings. A connecting plate 22 is threadedly connected to the outside of the screw 21. A clamping plate 23 is provided on the side of the connecting plate 22. Handles 31 are provided at the outer ends of both the screw 21 and the lead screw 42. When performing a sealing test on a horizontal valve, to prevent the horizontal valve from loosening at the flange 15 connection, it is necessary to fix the horizontal valve. A clamping plate 23 is fixedly connected to the side of the clamping box 2 via the connecting plate 22. The horizontal valve is placed on the clamping plate 23 of the fixed connecting plate 22. Rotating the handle 31 on the outside of the screw 21 causes the threaded connecting plate 22 to move downwards. The moving connecting plate 22 then moves the clamping plate 23 downwards, completing the clamping and fixing of the horizontal valve and ensuring the stability of the horizontal valve testing process.

[0020] A gear 3 is fixedly sleeved on the upper end of the screw 21. A fixing plate 34 is fixedly installed on the upper end of the clamping box 2. A limiting pin 32 is movably installed inside the fixing plate 34. A movable plate 35 is fixedly installed outside the limiting pin 32. When the handle 31 drives the gear 3 to rotate, the gear 3 drives the screw 21 to rotate. After the clamping plate 23 is adjusted, in order to prevent loosening during the horizontal valve testing process and cause the handle 31 to rotate, the limiting pin 32 is pulled upward while the handle 31 drives the gear 3 to rotate. The limiting pin 32 is externally sleeved... A spring 33 is connected at one end to a movable plate 35 and at the other end to a fixed plate 34. A limiting pin 32 drives the movable plate 35 to compress the spring 33. After the gear 3 is adjusted, the limiting pin 32 is released, and the compressed spring 33 needs to be restored to its original position. The spring 33 can push the movable plate 35 and the limiting pin 32 to move downward. The limiting pin 32 can engage with the teeth of the gear 3, thereby completing the limiting function of the gear 3 and ensuring that it will not loosen during the horizontal valve test and affect the stability of the test process.

[0021] The lower end of the platform 1 is connected to the recovery tank 4 through a through hole 12. A filter plate 41 is installed inside the recovery tank 4. A lead screw 42 is movably mounted inside the recovery tank 4 via a bearing. A cleaning brush 44 is threaded onto the outside of the lead screw 42. A slag collection box 46 is located on the other side of the recovery tank 4. An electric push rod 47 is fixedly installed inside the slag collection box 46. A stop block 48 is provided at the output end of the electric push rod 47. During a sealing test of the horizontal valve, part of the water flows into the recovery tank 4 through the through hole 12 at the upper end, and another part flows into the recovery tank 4 through the water pipe 14. Impurities are easily mixed into the water. The filter plate 41 can effectively remove these impurities from the water. The filter plate 41 is filtered, and the water flow can be circulated for reuse, reducing water waste during valve testing. When too many impurities accumulate on the surface of the filter plate 41, the handle 31 on the outside of the screw 42 is turned to rotate the screw 42. The rotation of the screw 42 moves the threaded cleaning brush 44 on the surface of the filter plate 41. The cleaning brush 44 pushes the impurities on the surface of the filter plate 41 into the slag collection box 46. The electric push rod 47 retracts the stop block 48 into the slag collection box 46. The impurities pushed by the cleaning brush 44 are pushed into the slag collection box 46 for centralized collection, avoiding the filter plate 41 from working for a long time and causing surface blockage, which would require workers to clean the filter plate 41 constantly, saving time and effort.

[0022] In the above scheme, a screen 11 is provided at the upper end of the through hole 12, a placement platform 13 is provided at the upper end of the platform 1, a water pipe 14 is placed on the placement platform 13, a flange 15 is provided on the side of the water pipe 14, a water pump 16 is connected to one side of the recycling box 4 through the water pipe 14, and a flange 15 is connected to the other side of the water pump 16 through the water pipe 14. The screen 11 can initially clean large pieces of debris at the upper end of the platform 1, preventing debris from falling into the recycling box 4 from the through hole 12. During the test of the horizontal valve, the connecting flange 15 is connected to both ends of the horizontal valve from the placement platform 13, and the test is carried out by turning on the water pump 16.

[0023] In the above scheme, a sliding rod 45 is fixedly installed inside the recycling bin 4, and a cleaning brush 44 is movably installed outside the sliding rod 45. The sliding rod 45 can limit and guide the movement of the cleaning brush 44, ensuring the stability of the movement of the cleaning brush 44.

[0024] Working principle:

[0025] In operation, this novel horizontal valve testing bench works as follows: When the handle 31 drives the gear 3 to rotate, pulling the limit pin 32 upwards causes the handle 31 outside the screw 21 to rotate. The rotation of the screw 21 causes the externally threaded connecting plate 22 to move downwards. The moving connecting plate 22 then moves the clamping plate 23 downwards, thus clamping and fixing the horizontal valve. Releasing the limit pin 32 restores the compressed spring 33 to its original position. The spring 33 pushes the movable plate 35 and the limit pin 32 downwards, allowing the limit pin 32 to engage with the gear. At the teeth of gear 3, the limiting function of gear 3 is completed. During the test of the horizontal valve, the connecting flange 15 is connected from the placement platform 13 to both ends of the horizontal valve. The test is carried out by turning on the water pump 16. The filter plate 41 can filter impurities in the water and the water flow can be circulated. When too many impurities accumulate on the surface of the filter plate 41, the cleaning brush 44 pushes the impurities on the surface of the filter plate 41 into the slag collection box 46 for collection. This avoids the filter plate 41 from working for a long time and causing surface blockage, which would require workers to clean the filter plate 41 constantly, saving time and effort.
