Description

Technical Field

[0001] This utility model relates to a vertically movable quick-cut blind valve, belonging to the technical field of quick-cut blind valves. Background Technology

[0002] Quick-cut blind valves are rapid shut-off devices in pipeline systems, primarily used in metallurgy, chemical, petroleum, and municipal industries. They are used to quickly and reliably block the flow of media within pipelines when necessary, ensuring pipeline maintenance, replacement, and the safe and normal operation of the system. Compared to traditional blind valves, the opening and closing of the valve plate is safer, faster, and more convenient. Existing quick-cut blind valves typically have a left-right sliding valve plate, occupying a larger area and limiting their application.

[0003] For example, Chinese utility model patent CN217328742U discloses a quick-cut blind valve for pipelines. The above-mentioned prior art has the following defects in use: First, the opening and closing of its switching plate is a left-right movement type, which occupies a large area; Second, when switching the opening and closing of the switching plate, the operator needs to push or pull the switching plate by hand, which is relatively laborious. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a quick-cut blind valve that occupies a small area and is easy to operate by moving up and down.

[0005] The up-and-down movable quick-cut blind valve of this utility model includes a movable valve body and a fixed valve body. The movable valve body and the fixed valve body are fixedly connected by multiple sets of tie rods and nuts. A working gap is provided between the movable valve body and the fixed valve body. A clamping mechanism corresponding to the working gap is connected to the movable valve body. The clamping mechanism is connected to a clamping drive mechanism. A valve plate is movably inserted into the working gap in the vertical direction. A support plate is fixedly connected between the movable valve body and the fixed valve body. A mounting plate is fixedly connected between the tops of the two support plates. A lifting drive mechanism is mounted on the mounting plate. The output end of the lifting drive mechanism is fixedly connected to the valve plate.

[0006] Furthermore, top wheel frames are fixedly connected to both the left and right sides of the fixed valve body, and top wheels are rotatably connected to each top wheel frame.

[0007] Furthermore, each of the aforementioned pull rods is rotatably connected to a retaining ring corresponding to the valve plate.

[0008] Furthermore, each of the retaining rings is provided with a limiting platform on its front side.

[0009] Furthermore, the lifting drive mechanism is a worm gear screw jack, in which the screw passes through the mounting plate and is fixedly connected to the valve plate, and the worm shaft of the worm gear screw jack is connected to a drive component.

[0010] Furthermore, the driving component is a handwheel.

[0011] Working principle and process:

[0012] When switching the valve plate between opening and closing, the clamping drive mechanism is activated first to release the clamping mechanism from the valve plate. Then, the drive component is activated to move the screw of the worm gear screw jack up or down, thereby moving the valve plate up or down. When the valve plate is in position, the clamping drive mechanism reverses its action to re-clamp the valve plate, thus realizing the switching between opening and closing the valve plate.

[0013] The advantages of this utility model compared with the prior art are:

[0014] The up-and-down movable quick-cut blind valve of this utility model has an up-and-down movable valve plate that switches the opening and closing of the valve plate, which occupies a smaller area and is therefore more convenient to use.

[0015] The up-and-down movable quick-cut blind valve of this utility model has a valve plate driven by a drive component. It uses a worm gear transmission to reduce speed while amplifying torque, so that only a small force is needed to lift a large load. Therefore, there is no need for operators to push or pull by hand, making operation more labor-saving. Attached Figure Description

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] like Figures 1 to 3As shown, the up-and-down movable quick-cut blind valve of this utility model includes a movable valve body 1 and a fixed valve body 10. The movable valve body 1 and the fixed valve body 10 are fixedly connected by multiple sets of tie rods 4 and nuts 5. A working gap is provided between the movable valve body 1 and the fixed valve body 10. A clamping mechanism 9 corresponding to the working gap is connected to the movable valve body 1. The clamping mechanism 9 is connected to a clamping drive mechanism 2. A valve plate 6 is movably inserted into the working gap in the vertical direction. A support plate 3 is fixedly connected between the movable valve body 1 and the fixed valve body 10. An installation plate 15 is fixedly connected between the tops of the two support plates 3. A lifting drive mechanism is installed on the installation plate 15. The output end of the lifting drive mechanism is fixedly connected to the valve plate 6.

[0023] When switching the valve plate 6 between opening and closing, the clamping drive mechanism 2 is activated first, which drives the clamping mechanism 9 to release the clamping of the valve plate 6. Then, the lifting drive mechanism is activated to drive the valve plate 6 to move up or down. When the valve plate 6 is in position, the clamping drive mechanism 2 reverses its action, thereby driving the clamping mechanism 9 to re-clamp the valve plate 6, thus realizing the switching of the valve plate 6 between opening and closing.

[0024] Example 2:

[0025] like Figures 1 to 3 As shown, based on Example 1,

[0026] Furthermore, top wheel frames 12 are fixedly connected to both the left and right sides of the fixed valve body 10, and top wheels 13 are rotatably connected to each top wheel frame 12. The top wheels 13 abut against the rear side of the valve plate 6, thereby preventing hard friction between the valve plate 6 and the fixed valve body 10 when the valve plate 6 moves up or down, thus providing a protective function.

[0027] Furthermore, each of the aforementioned pull rods 4 is rotatably connected to a retaining ring 11 corresponding to the valve plate 6. The retaining ring 11 corresponds to the left and right side walls of the valve plate 6, thereby preventing the valve plate 6 from scraping against the pull rod 4 when it moves upward or downward, thus providing a protective function.

[0028] Furthermore, each of the retaining rings 11 is provided with a limiting platform 14 on its front side. The rear end face of the limiting platform 14 can limit the front side of the valve plate 6, thereby preventing hard friction between the valve plate 6 and the clamping mechanism 9 when the valve plate 6 moves upward or downward, thus playing a protective role.

[0029] Furthermore, the lifting drive mechanism is a worm gear screw jack 7. The screw of the worm gear screw jack 7 passes through the mounting plate 15 and is fixedly connected to the valve plate 6. The worm shaft of the worm gear screw jack 7 is connected to a drive component 8. By actuating the drive component 8, the screw of the worm gear screw jack 7 can be driven to move up and down, thereby realizing the raising and lowering of the valve plate 6. The structure is simple and the operation is convenient.

[0030] Furthermore, the driving component 8 is a handwheel. The valve plate 6 can be raised or lowered by rotating the handwheel, resulting in a simple structure and low manufacturing cost. Additionally, the driving component 8 can also be driven by a motor, which improves the automation and reliability of the device.
