Description

Technical Field

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

[0002] A ball valve is a type of valve that controls the flow of fluid by rotating a ball. Its core structure consists of a valve body, a ball, a stem, and a sealing ring. Ball valves play a crucial control role in pipeline systems. Poor airtightness can lead to gas or liquid leakage. Leakage can not only affect the transport of media but also cause environmental pollution or safety accidents. Therefore, airtightness testing of ball valves is a critical quality control measure that is of great significance for ensuring the smooth operation of the entire production and use process.

[0003] Ball valve sealing performance testing devices typically use a fixed pressure test, which involves introducing a fixed pressure of gas into the inlet side of the ball valve and detecting whether there is any leakage at the outlet to determine the sealing performance. This testing method requires the valve body under test to be connected to the pipeline. Each connection and installation requires the operator to hold the valve body and fix its position and angle so that the valve body can be accurately connected to the pipeline. This increases the workload of the operator and reduces the testing efficiency of the ball valve. Therefore, this application proposes a ball valve testing device. Utility Model Content

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0041] Please see Figures 1-5 This utility model provides a technical solution: a ball valve testing device, including an upward-opening immersion tank 11, a protective shell 12 fixedly installed on the top of the left end of the immersion tank 11, a through-hole 24 opened at the bottom of the protective shell 12, a linear module 21 fixedly installed on the inner wall of the protective shell 12, an L-shaped welding plate 22 fixedly installed on the sliding block in the linear module 21, the vertical part of the welding plate 22 passing through the through-hole 24 so that its horizontal part is located inside the immersion tank 11, and a sliding installation on the left end of the top of the welding plate 22. There is a movable base 31, and a left tube 32 is fixedly installed on the top of the movable base 31. A fixed seat 37 is fixedly installed on the right end of the horizontal part of the welding plate 22. A right tube 38 is fixedly inserted into the fixed seat 37. A movable plate 34 is also slidably installed on the horizontal part of the welding plate 22. A storage seat 35 is installed on the top of the movable plate 34. A valve body 36 is placed on the storage seat 35. The valve body 36 is located between the left tube 32 and the right tube 38. An air intake pipe 33 that is internally connected is fixedly connected to the top of the left tube 32.

[0042] The PLC controller 23 controls the linear module 21 to move the welding plate 22 upward, so that the structure on the horizontal part of the welding plate 22 is exposed above the water surface. Then, the valve body 36 to be tested is placed on the plant base. Then, the hydraulic rod 43 is controlled to push the fixing block 44, thereby moving the moving base 31 within the slot 25. In this way, the left tube 32 will align with the left end of the valve body 36 and push the valve body 36 closer to the right tube 38. Finally, the valve body 36 can be aligned between the left tube 32 and the right tube 38. After the valve body 36 is aligned and installed, the PLC controller 23 is controlled again to move the linear module 21 to move the welding plate 22 downward. In this way, the left tube 32, the right tube 38 and the valve body 36 can be fully submerged in the water of the soaking tank 11. Finally, gas is injected into the left tube 32 through the air inlet pipe 33 and passed through the right tube 38 to check whether bubbles are generated.

[0043] See Figures 2-4A slot 25 is provided on the horizontal part of the welding plate 22. The movable base 31 and the movable plate 34 are both located in the slot 25 and can move left and right between them. Two positioning rods 41 are fixedly installed between the two ends of the inner wall of the slot 25. Two through positioning holes 42 are provided on the side of the movable base 31 and the movable plate 34. The two positioning holes 42 on the movable base 31 and the movable plate 34 are respectively movably sleeved on the two positioning rods 41. Through the two positioning rods 41 in the slot 25, the movable base 31 and the movable plate 34 can be more stable when moving in the slot 25, and the skew of the movable base 31 and the movable plate 34 can be avoided.

[0044] See Figure 3 and Figure 4 A fixing block 44 is fixedly installed at the bottom of the movable base 31. A hydraulic rod 43 is fixedly installed at the left end of the bottom of the horizontal section of the welding plate 22. The telescopic end of the hydraulic rod 43 is fixedly connected to the fixing block 44 at the bottom of the movable base 31. By controlling the hydraulic rod 43, the fixing block 44 can be moved, thereby moving the movable base 31 and the left tube 32 on its top. After the left tube 32 contacts the valve body 36, it can also push the valve body 36 closer to the right tube 38, and finally complete the docking installation of the left tube 32, the valve body 36 and the right tube 38.

[0045] See Figure 2 and Figure 3 The storage base 35 is U-shaped, and the diameter of the bottom arc of the inner wall of the storage base 35 is the same as the diameter of the outer wall of the valve body 36. The center of the valve body 36, the center of the left tube 32, and the center of the right tube 38 are all located on the same horizontal axis. This allows the valve body 36 to be placed directly between the storage bases 35, so that the left tube 32, the valve body 36, and the right tube 38 can be precisely connected.

[0046] See Figure 4 Flange covers are provided at both ends of the valve body 36. Flange covers are provided at the ends of the left pipe body 32 and the right pipe body 38 near the valve body 36. Sealing gaskets are provided on the inner walls of the two flange covers. The flange covers at both ends of the valve body 36 can be inserted into the two flange covers respectively. By covering the flange covers at the ends of the left pipe body 32 and the right pipe body 38 with the flange covers at both ends of the valve body 36, and with the sealing gaskets inside the flange covers, the sealing performance after the three are connected can be further improved.

[0047] See Figure 1 A PLC controller 23 is fixedly installed on the outer wall of the protective housing 12. The PLC controller 23 is linearly connected to the linear module 21 on the inner wall of the protective housing 12. By operating the PLC controller 23, the linear module 21 can be controlled to drive the welding plate 22 to adjust its position and height, thereby driving the structure on the horizontal part of the welding plate 22 to rise and fall in height.

[0048] See Figure 4 and Figure 5 The center of the right end of the movable base and the movable plate 34 is provided with a groove. A spring 51 is fixedly connected in both grooves. The right half of the two springs 51 extends to the outside of the groove. When the hydraulic rod 43 retracts and drives the movable base 31 back to its original position, the spring 51 will not be squeezed and will not release its elastic force, so that the valve body 36 can be separated from the left tube 32 and the right tube 38, making it convenient to directly remove the valve body 36 from the seat 35.

[0049] See Figure 1 Support legs 13 are fixedly installed at the four corners of the bottom of the soaking tank 11. A drain pipe 14 connected to the bottom of the tank is fixedly connected to the outer wall of the soaking tank 11. A sealing cap is threaded onto the end of the drain pipe 14. The support legs 13 support the soaking tank 11, which can be positioned at a suitable height. The drain pipe 14 facilitates the drainage of water from the soaking tank 11, preventing the water from becoming turbid and affecting the test observation.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
