Description

Integrated dual-drive controlled fluoropolymer-lined diaphragm valve Technical Field

[0001] This utility model relates to the field of diaphragm valves, specifically an integrated dual-drive control fluoropolymer-lined diaphragm valve. Background Technology

[0002] A diaphragm valve is a gate valve that uses a diaphragm as the opening and closing element to close the flow channel, cut off the fluid, and separate the valve body cavity from the valve cover cavity. The diaphragm is usually made of elastic, corrosion-resistant, and non-permeable materials such as rubber and plastic. The valve body is mostly made of plastic, fiberglass, ceramic, or metal lined with rubber. It has a simple structure, good sealing and corrosion resistance, and low fluid resistance. It is used for low-pressure, low-temperature, highly corrosive, and media containing suspended substances. According to the structural form, there are ridge type, gate type, and gate valve, etc. According to the driving method, there are manual, pneumatic, and electric types. Some also use dual-drive control.

First, they lack a limit function, which causes the valve stem to easily rotate after manual operation, hindering the use of the diaphragm valve. Second, the connection length of the diaphragm valve cannot be adjusted, making it unsuitable for different installation space lengths. When connecting to long-distance pipelines, additional connecting pipes are required. Therefore, an integrated dual-drive control fluoropolymer-lined diaphragm valve is proposed to address these issues. Summary of the Invention

By setting the operating component 7, the insert rod 707 can be inserted into the insert hole 704 to fix the rotating box 701, thereby limiting the valve stem 2, improving the stability of the valve stem 2, and preventing the valve stem 2 from rotating. By setting the adjusting component 8, the service length of the entire valve body 1 can be extended by adjusting the moving tube 4, which can meet the needs of different installation space lengths.

[0028] Referring to Figures 1, 3, and 4, the surface of the positioning block 802 is provided with several slots 804. The surface of the positioning shell 803 is fixedly connected to a limiting box 805. The inner cavity of the limiting box 805 is provided with a movable frame 806. A locking block 807 is fixedly connected to one side of each of the two movable frames 806. One side of the locking block 807 passes through the limiting box 805 and the positioning shell 803 and extends into the inner cavity of the slot 804.

[0029] Referring to Figures 1, 3, and 4, an adjusting box 809 is fixedly connected to the top of the connecting pipe 3. The inner cavity of the adjusting box 809 has two moving blocks 810. Moving rods 811 are fixedly connected to opposite sides of each of the two moving blocks 810. A third spring 812 is sleeved on the surface of the moving rod 811.

One end of the second spring 808 is fixedly connected to the inner wall of the limit box 805, and both ends of the third spring 812 are fixedly connected to the adjustment box 809 and the moving blocks 810 respectively. By setting the third spring 812, the two moving blocks 810 can be easily moved to the middle for reset. By setting the cam 814, the moving blocks 810 can be pushed.

[0030] Referring to Figures 1 and 2, there are six fixing brackets 709, which are evenly distributed on the surface of the fixing shell 703.

By setting the pneumatic connectors 6, the valve can be easily operated pneumatically.

[0031] Working principle: When the user needs to operate the valve body 1, they can hold the handwheel 702 and simultaneously press the two operating blocks 708 towards the center. The operating blocks 708 drive the two limiting blocks 705 to move towards the center, pressing the first spring 706 until the limiting blocks 705 drive the insert rod 707 out of the insertion hole 704, releasing the restriction on the insert rod 707. Then, the handwheel 702 can be turned, which drives the valve stem 2 to rotate, thus adjusting the entire valve state. After adjustment, the restriction on the operating blocks 708 is released. At this time, the first spring 706 returns to its original position, causing the two limiting blocks 705 to move away from each other. The limiting blocks 705 drive the insert rod 707 to insert into the insertion hole 704, completing the restriction on the limiting box 805, valve stem 2, and handwheel 702, preventing the valve stem 2 from rotating on its own. When it is necessary to connect to a pipeline over a long distance, Rotating the rotating block 815 causes the cam 814 to rotate and press the moving block 810 through the cooperation of the rotating rod 813. The moving block 810, through the cooperation of the moving rod 811 and the moving frame 806, causes the two locking blocks 807 to move away from each other and out of the slot 804, releasing the restriction on the positioning block 802. Then the moving tube 4 and the connecting plate 5 can be moved to the right. After moving to the required length, the rotating block 815 is released. At this time, the second spring 808 and the third spring 812 reset and drive the two moving frames 806 to move towards the middle. The moving frame 806 drives the locking block 807 to insert into the slot 804, restricting the positioning block 802, thereby fixing the fixing plate 801 and the moving tube 4. By adjusting the moving tube 4, the service length of the entire valve body 1 can be extended to adapt to the needs of different installation space lengths.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
