Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, specifically a new type of flow meter pressure testing tooling equipment. Background Technology

[0002] Flow meters are widely used in various industrial and domestic fields, undertaking the precise measurement of fluid flow. Whether in the petroleum, chemical, water supply, or environmental protection industries, the accuracy and stability of flow meters are crucial to the safety and economy of the entire system. To ensure the normal operation of flow meters, pressure testing is an indispensable part of the production, inspection, and maintenance process. Pressure testing verifies whether the flow meter can function properly under specific operating pressures, ensuring its accuracy and reliability. Existing flow meter pressure testing fixtures typically only clamp a single flow meter, reducing work efficiency and limiting their application to only one type of flow meter. This design restricts the flexibility and versatility of the fixture. Therefore, this patent proposes a novel flow meter pressure testing fixture to address these issues. Utility Model Content The purpose of this utility model is to provide a new type of flow meter pressure testing equipment to solve the problems mentioned in the background art.

[0003] To achieve the above objectives, this utility model provides the following technical solution: a novel flow meter pressure testing fixture, comprising a switch mounting plate, side plates fixed on both sides of the switch mounting plate, a cylinder mounting plate fixed between the two side plates, a mold support column fixed at the bottom end of the cylinder mounting plate, a lower cover plate fixed at the bottom end of the mold support column, a plurality of first cylinders fixed at the top end of the cylinder mounting plate, a top cover fixed at the bottom end of the first cylinder after passing through the cylinder mounting plate, a bottom cover fixed at the top end of the lower cover plate corresponding to the top cover, a plurality of pneumatic push valves fixed on both sides of the two side plates, and a sealing device corresponding to the bottom cover at the top end of the lower cover plate.

[0004] Preferably, the sealing device includes a fixed base fixed to the top of the lower cover plate, a movable frame fixed to the top of the fixed base, a first screw screwed to the top of the movable frame, a movable block rotatably connected to the bottom of the first screw screw, the movable block slidably connected inside the movable frame, a slider slidably connected inside the fixed base, a mounting base fixed to the top of the slider, a sealing sensor slidably connected to the end of the mounting base near the top cover, and a second screw screwed to one end of the movable block, the second screw rotatably connected to the sealing sensor.

[0005] Preferably, a second cylinder is fixed between the switch mounting plate and the cylinder mounting plate. The output end of the second cylinder passes through the cylinder mounting plate and is fixed to a base plate. A water storage tank is fixed to the bottom end of the base plate, and a support frame is fixed to the bottom end of the water storage tank.

[0006] Preferably, a drain pipe is fixedly connected to the bottom of the water storage tank, and a valve is installed on the drain pipe.

[0007] Preferably, the bottom end of the support frame is equipped with multiple casters, which have a brake function.

[0008] Preferably, a controller is installed on one side of the water storage tank, and the controller is electrically connected to the blocking sensor.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The flowmeter is sealed by the top and bottom covers, which are moved downwards by the first cylinder. A pneumatic push valve controls the sealing of both ends of the product by the first cylinder. This allows for pressure testing of one unit at a time or four units at a time, improving work efficiency. Additionally, a sealing device allows a sealing sensor to seal the sides of the flowmeter. The sealing sensor detects the sealing condition of the flowmeter. When testing different flowmeters, rotating the first screw moves the moving block up and down, adjusting the height of the sealing sensor. Rotating the second screw moves the sealing sensor back and forth, facilitating sealing of flowmeters of different sizes. This design is highly practical. A pneumatic push valve controls the second cylinder, which in turn moves the switch mounting plate downwards, allowing the flowmeter to enter the water tank. This facilitates immersion in water for pressure testing, reducing manual labor. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Flow meters are widely used in various industrial and domestic sectors, undertaking the precise measurement of fluid flow. Whether in the petroleum, chemical, water supply, or environmental protection industries, the accuracy and stability of flow meters are crucial to the safety and economy of the entire system. To ensure the normal operation of flow meters, pressure testing is an indispensable part of the production, inspection, and maintenance process. Pressure testing verifies whether the flow meter can function properly under specific operating pressures, ensuring its accuracy and reliability.

[0014] Example 1: like Figures 1-3 As shown, this utility model provides a technical solution: a novel flow meter pressure testing fixture, including a switch mounting plate 1, side plates 9 fixed on both sides of the switch mounting plate 1, a cylinder mounting plate 2 fixed between the two side plates 9, a mold support column 3 fixed at the bottom end of the cylinder mounting plate 2, a lower cover plate 4 fixed at the bottom end of the mold support column 3, a plurality of first cylinders 6 fixed at the top end of the cylinder mounting plate 2, a top cover 7 fixed at the bottom end of the output end of the first cylinder 6 after passing through the cylinder mounting plate 2, a bottom cover 8 corresponding to the top cover 7 fixed at the top end of the lower cover plate 4, a plurality of pneumatic push valves 10 fixed on both sides of the two side plates 9, and a sealing device corresponding to the bottom cover 8 set at the top end of the lower cover plate 4. The sealing device includes a fixed base 11 fixed to the top of the lower cover plate 4. A movable frame 12 is fixed to the top of the fixed base 11. A first screw 13 is screwed to the top of the movable frame 12. A movable block 14 is rotatably connected to the bottom of the first screw 13. The movable block 14 is slidably connected inside the movable frame 12. A slider 16 is slidably connected inside the fixed base 11. A mounting base 17 is fixed to the top of the slider 16. A sealing sensor 18 is slidably connected to one end of the mounting base 17 near the top cover 7. A second screw 15 is screwed to one end of the movable block 14. The second screw 15 is rotatably connected to the sealing sensor 18. A second cylinder 24 is fixed between the switch mounting plate 1 and the cylinder mounting plate 2. The output end of the second cylinder 24 passes through the cylinder mounting plate 2 and is fixed to a base plate 5. A water storage tank 19 is fixed to the bottom of the base plate 5. A support frame 21 is fixed to the bottom of the water storage tank 19.

[0015] It is important to note that the top cover 7 is moved downwards by the first cylinder 6, sealing the top and bottom ends of the flowmeter by the top cover 7 and the bottom cover 8. The pneumatic push valve 10 controls the sealing effect of the first cylinder 6 on both ends of the product. This allows for pressure testing of individual units or all four units at once. Furthermore, the sealing device allows the sealing sensor 18 to seal the side of the flowmeter. The end of the flowmeter away from the sealing sensor 18 has an air hole. By injecting air into the air hole and pressurizing, the sealing sensor 18 detects the sealing condition of the flowmeter. When different flowmeters are tested... During testing, rotating the first screw 13 causes the moving block 14 to move up and down, thereby adjusting the height of the blocking sensor 18. Rotating the second screw 15 causes the blocking sensor 18 to move back and forth, making it easy to block flow meters of different sizes. This method is highly practical. One pneumatic push valve 10 controls the second cylinder 24, which in turn moves the switch mounting plate 1 downward, allowing the flow meter to enter the water storage tank 19. This facilitates the flow meter being placed in water for testing during the air pressure test, reducing manual labor.

[0016] Example 2: like Figure 4 and Figure 5 As shown, a drain pipe 20 is fixedly connected to the bottom of the water storage tank 19, and a valve is installed on the drain pipe 20. Multiple casters 23 with anti-brake function are installed at the bottom of the support frame 21. A controller 22 is installed on one side of the water storage tank 19, and the controller 22 is electrically connected to the sealing sensor 18.

[0017] It should be noted that by fixing the drain pipe 20 at the bottom of the water storage tank 19, the water in the water storage tank 19 can be cleaned out when no testing is required. By setting the casters 23, the device can be easily moved to a designated position and fixed. In addition, the controller 22 is electrically connected to the sealing sensor 18. The sealing sensor 18 determines whether there is a medium leaking from the side gap of the flow meter based on the pressure decay rate, thereby assessing its sealing reliability.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
