Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a leakage alarm type gate valve. Background Art

[0002] The gate valve is an opening and closing part, the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually the sealing surface will be welded with metal materials to increase wear resistance, such as cladding 1Cr13, STL6, stainless steel, etc.

[0038] Example 1

[0039] Please refer to Figure 1-6A leakage alarm gate valve comprises a valve body 1 and a valve plate 15. An inclined surface 2 is provided on one side of the inner bottom surface of the valve body 1. A slide groove 21 is provided on the right side of the inclined surface 2. A detection part for detecting whether the gate valve is leaking is slidably connected to the inner surface of the slide groove 21. An installation box 25 is fixedly connected to the right side of the lower surface of the valve body 1. An early warning part is fixedly connected to the inner side of the installation box 25. A slide groove block 4 is fixedly connected to the front side of the installation box 25. A fixing part is slidably connected to the inner surface of the slide groove block 4. A flange 11 is fixedly connected to the left side, right side and upper side of the valve body 1. A valve cover 12 is fixedly connected to the upper surface of the flange 11 by bolts. A hand wheel 13 is rotatably connected to the upper surface of the valve cover 12. A valve stem 14 is threadedly connected to the center of the hand wheel 13. The valve stem 14 sequentially passes through the hand wheel 13 and the valve cover 12 and extends to the inside of the valve body 1 and is rotatably connected to the valve plate 15. The valve plate 15 is inserted into the inner bottom surface of the valve body 1 and is slidably arranged. The detection part includes a slider 22, which is slidably arranged inside the slide groove 21, and a slide groove 23 is provided on the inner bottom surface of the valve body 1 at the lower side of the slide groove 21, and a slider 24 is slidably connected to the inner surface of the slide groove 23, and a rotating shaft 26 is fixedly connected to the center position of the inner surface of the installation box 25, and a rotating plate 27 is rotatably connected to the outer surface of the rotating shaft 26, and a rotating plate 28 is rotatably connected to the outer surface of the rotating shaft 26 located on the outer side of the rotating plate 27, and a tension spring 29 is rotatably connected to both sides of the rotating plate 28 on both sides of the rotating plate 27, and one end of the two tension springs 29 is rotatably connected to both sides of the rotating plate 28. The slider 24 and the slide groove 23 are provided with corresponding inclined surfaces.

[0040] Implementation process: The initial state of the fixed block 41 is located inside the slide block 4. Because the handwheel 13 and the valve stem 14 are threadedly connected, the handwheel 13 and the valve cover 12 are rotatably connected. The handwheel 13 is rotated to drive the valve stem 14 to move downward, thereby driving the valve plate 15 rotatably connected to the valve stem 14 to move downward, so that the valve plate 15 is stuck in the inner bottom surface of the valve body 1 for sealing. When the gate valve leaks, the leaked liquid increases the flow rate of the liquid through the inclined surface 2 and impacts the slide groove 1 21, driving the slide groove 1 21 to move in the direction of the slider 2 24, pushing the slider 2 24 to move downward inside the slide groove 23, and the movement of the slider 24 drives the rotating plate 28 to rotate counterclockwise around the rotating shaft 26 and stretch the tension spring 29. When the rotating plate 28 When the angle between the rotating plate 28 and the rotating plate 1 27 is greater than one hundred and eighty degrees, the rotating plate 1 27 rotates downward clockwise around the rotating shaft 26 under the elastic force of the tension spring 29, so that one end of the rotating plate 28 contacts the inner bottom surface of the installation box 25, and one end of the rotating plate 1 27 contacts the switch button 3 and presses the switch button 3, thereby driving the alarm 31 to sound an alarm to remind the staff of the gate valve leakage. After the maintenance is completed, the rotating plate 28 is pulled upward to make the rotating plate 28 and the rotating plate 1 27 rotate around the rotating shaft 26 to reset. At the same time, the rotating plate 28 pushes the slider 2 24 to move upward inside the slide groove 23. The upward movement of the slider 24 pushes the slider 1 22 to move in the opposite direction for reset, which is convenient for the next use.

[0041] Implementation benefits: It realizes the detection and alarm function of gate valve leakage.

[0044] Implementation process: when the seal needs to be released, pull the connecting plate 44 forward to drive the connecting rod 43 and the fixed block 41 to move synchronously inside the slide block 4 and compress the spring 42, then rotate the connecting plate 44 ninety degrees, loosen the connecting plate 44, and allow the fixed block 41 to pass through the installation box 25 under the elastic force of the spring 42 and contact the lower surface of the rotating plate 28, thereby fixing the position of the rotating plate 28, thereby fixing the positions of the slider 24, the slider 1 22 and the rotating plate 1 27, preventing the liquid from impacting the slider 1 22 when the gate is opened, driving the rotating plate 1 27 to contact the switch button 3 and trigger the alarm 31, then reversely rotate the handwheel 13 to drive the valve stem 14 to move upward, and the movement of the valve stem 14 drives the valve plate 15 to move upward, thereby releasing the seal.
