Description

Technical Field

[0001] This utility model relates to the field of flat plate valve equipment technology, and in particular to a flat plate valve body with docking function. Background Technology

[0002] The flat plate valve body is one of the core components of a valve, primarily responsible for the shut-off or regulation of fluid media. Its structural design directly affects the valve's sealing performance and durability. The valve body is usually made of cast steel, stainless steel, or alloy steel, and is processed using casting or forging processes. It possesses sufficient strength and rigidity to withstand the pressure and vibration of the pipeline system. Internally, it contains key components such as the valve stem, valve plate, and sealing components. The valve plate opens or closes through vertical movement, and the sealing surface uses materials such as polytetrafluoroethylene (PTFE) and metal to ensure sealing performance. It is widely used in petrochemical, power, and water treatment fields, such as main valves for oil pipelines and high-pressure water pump control in sewage treatment plants.

[0003] Currently, existing flat valves are connected to pipelines via flanges. Flange connections require that the two flanges be parallel and aligned in the center before bolts are inserted and tightened evenly. For large-diameter pipelines, it is difficult to align them accurately manually, requiring the assistance of hoisting equipment. This results in low installation efficiency, and bolts exposed to air for extended periods are prone to rusting. During disassembly, problems such as jamming or breakage may occur, further increasing maintenance costs. Utility Model Content

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] Please combine Figures 1 to 4 The flat valve body with docking function in this embodiment includes: a device body 1, a top cover 2 fixedly connected to the top of the device body 1, an electric telescopic rod 3 fixedly connected to the top of the top cover 2, the telescopic rod of the electric telescopic rod 3 passing through the top cover 2 and being slidably connected to the top cover 2 in a sealed manner, a U-shaped connecting block 4 fixedly connected to the telescopic rod of the electric telescopic rod 3, a gate plate 5 fixedly connected to the bottom of the U-shaped connecting block 4, two pipe ports 7 fixedly connected to the device body 1, one end of each of the two pipe ports 7 being fixedly connected to a corresponding connecting mechanism, and a corresponding water pipe 13 connected to each of the two connecting mechanisms.

[0016] Through the above technical solution, the equipment body 1 is connected to two water pipes 13 by two connecting mechanisms, which makes the connection faster and more convenient, greatly improves the installation efficiency of the equipment, and avoids the use of too many bolts, which would lead to inconvenient disassembly, bolt jamming, breakage and other risks, and greatly reduces the cost of equipment maintenance.

[0017] The connecting mechanism includes a connector 12, on which two connecting rods 14 are slidably connected. One end of each connecting rod 14 is fixedly connected to a corresponding locking block 15. Two slots 16 are opened on the water pipe 13, and the two locking blocks 15 are adapted to the corresponding slots 16. The other end of each connecting rod 14 is rotatably connected to a corresponding handle 17. A corresponding spring 18 is sleeved on each connecting rod 14. The model of the main body 1 of the equipment is Z43WBF-16C.

[0018] With the above technical solution, the connecting mechanism engages with the slot 16 on the water pipe 13 through the locking block 15, so that the water pipe 13 is firmly fixed in the connecting mechanism. When disassembly is required, simply open the handle 17 to separate the locking block 15 from the slot 16 and easily remove the water pipe 13.

[0019] A filter screen 6 is fixedly connected to the gate 5. A first sealing ring 8 is provided in each of the two pipe openings 7. A second sealing ring 9 is provided at the bottom of the upper cover 2. A third sealing ring 21 is provided in each of the two connectors 12. The electric telescopic rod 3 is model LBHM25.

[0020] Through the above technical solution, the filter screen 6 can filter the water flow when the water flow is open, and the first sealing ring 8, the second sealing ring 9 and the third sealing ring 21 cooperate to seal the internal interface of the equipment to prevent water from overflowing from the interface.

[0021] Each of the four handles 17 is rotatably connected to a corresponding hook 19, and one end of each of the two connectors 12 is fixedly connected to two corresponding buckles 20. Each of the four hooks 19 is adapted to the corresponding buckle 20.

[0022] Through the above technical solution, the four hooks 19 are adapted to the four buckles 20, and the four handles 17 are fixed after the equipment docking is completed to prevent them from being accidentally opened and causing the docking to break.

[0023] The upper cover 2 is provided with multiple connecting bolts 10, and the upper cover 2 is fixedly connected to the main body 1 of the equipment through the multiple connecting bolts 10.

[0024] Through the above technical solution, multiple connecting bolts 10 can firmly fix the top cover 2 onto the main body 1 of the equipment and enhance the sealing performance of the top cover 2.

[0025] A protective shell 11 is fixedly connected to the top of the cover 2, and the protective shell 11 is compatible with the electric telescopic rod 3.

[0026] Through the above technical solution, the protective shell 11 plays a protective role for the electric telescopic rod 3, preventing the electric telescopic rod 3 from being exposed to the outside and damaged, thus preventing it from working properly.

[0027] The implementation principle of a flat valve body with docking function in this application embodiment is as follows: In use, the operator opens the four handles 17 in sequence. The upward opening of the four handles 17 causes the four connecting rods 14 to rise, which in turn causes the four locking blocks 15 to rise, allowing the two water pipes 13 to be inserted into the two connectors 12 respectively. Then, the four handles 17 are released, causing the four locking blocks 15 to fall and engage with the four locking slots 16, firmly fixing the two water pipes 13 within the two connectors 12, completing the connection operation. When it is necessary to open the gate to release water, the electric telescopic rod 3 is activated. The telescopic rod of the electric telescopic rod 3 extends and retracts, causing the U-shaped connecting block 4 to rise. The rising U-shaped connecting block 4 causes the gate plate 5 to rise, allowing the water flow to pass through the filter screen 6 for release. When it is necessary to close the gate to cut off the flow, the electric telescopic rod 3 is activated again. The telescopic rod of the electric telescopic rod 3 extends and retracts, causing the gate plate 5 to descend and block the water flow, completing the overall operation.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
