Description

Technical Field

[0001] The utility model relates to a valve, in particular to a valve which is convenient for maintenance and belongs to the technical field of valves. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. There are many types of valves, including gate valves. Gate valves are also called manual knife-type gate valves. Knife-type gate valves are valves in which the gate and the valve seat are always in close contact and sealed. The principle is that a circular opening of the same diameter is opened on the gate, and the circular opening on the gate is completely separated and matched with the diameter by opening and closing the gate. The advantage of this valve is that there is no groove in the valve body diameter, the medium will not be blocked, and it has full-diameter flow characteristics. Its sealing structure can be divided into soft sealing and hard sealing structures.

[0003] The existing plug-in valves generally have a strong integrity, and some parts are not easy to disassemble, which makes it inconvenient to operate during maintenance. When it is found that some parts need to be repaired or replaced, it is difficult to disassemble them quickly, which will eventually greatly extend the time spent on the entire maintenance process and bring many inconveniences to production work. Therefore, in view of the above problems, a valve that is easy to maintain is proposed. Utility Model Content

In particular, the C-shaped plug plate on the top connecting plate can be inserted into the C-shaped through groove to achieve the initial connection between the top connecting plate and the gate guide frame. At this time, the top connecting plate cannot be arbitrarily displaced on the horizontal plane, which can facilitate the subsequent use of the first connecting bolt to fix the two together, reducing the operating difficulty of maintenance personnel and improving maintenance efficiency.

The above-mentioned structural form can make all the components constituting the valve as a whole have detachability, that is, the valve as a whole has a high degree of detachability, and then the parts that need to be replaced or repaired can be quickly disassembled and installed during maintenance, thereby achieving the purpose of reducing the operating difficulty of maintenance personnel and shortening the maintenance time.

[0030] like Figure 2 As shown, a C-shaped through groove 211 is provided on the first connecting ear plate 21, and C-shaped plug plates 41 are fixedly arranged on both sides of the lower end surface of the top connecting plate 4. The size of the C-shaped plug plate 41 is consistent with that of the C-shaped through groove 211. The C-shaped plug plate 41 on the top connecting plate 4 can be inserted into the C-shaped through groove 211 to achieve the initial connection between the top connecting plate 4 and the gate guide frame 2. At this time, the top connecting plate 4 cannot be arbitrarily displaced on the horizontal plane, which can facilitate the subsequent use of the first connecting bolt 71 to fix the two together, thereby reducing the operating difficulty of maintenance personnel and improving maintenance efficiency.

[0031] like Figure 3 As shown, the sliding plug plate 3 includes a mounting plate 31, a plug plate body 32 is fixedly provided on the lower end surface of the mounting plate 31, end sliders 311 are fixedly provided at both ends of the mounting plate 31, and the width of the plug plate body 32 is smaller than the width of the mounting plate 31. The above-mentioned structural form can realize the sliding connection between the plug plate body 32 and the gate guide frame 2 through the mounting plate 31.

[0032] like Figure 2 As shown, a vertically arranged guide rail 22 is fixedly provided on the inner wall of the gate guide frame 2, and the end slider 311 is slidably provided in the guide rail 22. The combination of the end slider 311 and the guide rail 22 enables the mounting plate 31 to slide up and down only along the guide rail 22 in the vertical direction without lateral displacement.

[0033] like Figure 2 As shown, a threaded barrel 42 is fixedly provided at the center of the upper end surface of the top connecting plate 4, and the operating rod 5 includes a threaded rod 51 threadedly connected to the threaded barrel 42, and a handwheel 52 is fixedly provided on the top of the threaded rod 51. The above-mentioned structural form can drive the threaded rod 51 to rotate through the handwheel 52. Since the threaded rod 51 is threadedly connected to the threaded barrel 42, the threaded rod 51 will move up and down while rotating, thereby driving the sliding plug plate 3 connected to its lower part to move up and down.

[0034] like Figure 4 As shown, the connecting member 6 includes a rotating connecting block 61, and second connecting ear plates 62 are fixedly arranged on both sides of the rotating connecting block 61. The second connecting ear plates 62 are detachably connected to the upper end surface of the sliding plug plate 3 through second connecting bolts 72. The rotating connecting block 61 is rotatably connected to the bottom end of the threaded rod 51.

The width of the through groove 111 is consistent with the width of the plug plate body 32. This structural form can allow the plug plate body 32 to slide up and down along the through groove 111, thereby controlling the degree of opening of the passage of the middle pipe section 11. In addition, the front and rear end surfaces of the middle pipe section 11 are both sealed and connected with a connecting plate 12, and a plurality of bolt holes arranged in a circular array are provided on the connecting plate 12. This structural form can realize the fixed connection between the valve as a whole and the pipe bodies at both ends, and provide the necessary conditions for the valve as a whole to be installed in the pipeline.

[0036] The use principle and use process of the utility model: in normal use, the hand wheel 52 is used to drive the threaded rod 51 to rotate. Since the threaded rod 51 is threadedly connected to the threaded tube 42, the threaded rod 51 will move up and down while rotating, thereby driving the sliding plug plate 3 connected to the lower part to slide up and down along the guide rail 22. The plug plate body 32, which is the main body of the sliding plug plate 3, will synchronously slide up and down along the through groove 111, thereby controlling the opening degree of the passage of the middle pipe section 11, and playing the role of adjusting the flow rate and flow rate;

[0037] When performing maintenance, first loosen the second connecting bolt 72 to separate the connecting member 6 from the sliding plug plate 3, and then loosen the first connecting bolt 71 to separate the gate guide frame 2 from the top connecting plate 4. At this time, the top connecting plate 4 and the joystick 5 connected thereto can be disassembled, and then the plug plate body 32 can be pulled out along the guide rail 22 to complete the entire disassembly of the valve, and the parts that need to be repaired can be processed separately. After the maintenance is completed, the installation work can be completed by reversing the above steps, which can improve the work efficiency of the entire maintenance process and reduce the difficulty of the maintenance personnel;

[0038] In particular, during the installation process after the maintenance is completed, the C-shaped plug plate 41 on the top connecting plate 4 can be inserted into the C-shaped through groove 211 to achieve the initial connection between the top connecting plate 4 and the gate guide frame 2. At this time, the top connecting plate 4 cannot be displaced arbitrarily on the horizontal plane, which can facilitate the subsequent use of the first connecting bolt 71 to fix the two together, thereby reducing the operating difficulty of maintenance personnel and improving maintenance efficiency.
