[0006] The effect achieved by the above components is as follows: when the filter needs to be installed, the staff first moves the fixed frame, and the fixed frame moves with the filter toward the fixed ring, and the clip on the fixed ring is inserted into the reserved hole of the fixed frame. At this time, the inclined surface of the trapezoidal block on the clip is squeezed by the inner wall of the reserved hole, and the trapezoidal block moves toward the inner direction of the groove, and the spring contracts. After the trapezoidal block moves through the reserved hole, the fixed frame and the fixed ring fit together. At the same time, under the action of the spring return force, the trapezoidal block moves out of the groove of the clip, and the trapezoidal block clamps the fixed frame, thereby achieving the effect of fixing the filter in the fixed frame, achieving the effect of fixing the filter through the filtering device, and achieving the effect of filtering the fluid impurities inside the valve body through the filter, thereby preventing impurities inside the fluid from sticking to the parts inside the valve body, thereby causing the valve body to be corroded, and improving the service life of the valve body.

[0007] Preferably, a pull plate is fixedly connected to the upper surface of the trapezoidal block, and a limiting hole is provided on the clamping member corresponding to the pull plate, and the size of the pull plate is larger than the size of the limiting hole.

[0008] The effect achieved by the above components is: by setting the pull plate, the contact area between the trapezoidal block and the staff's hands is increased, thereby making it easier for the staff to move the trapezoidal block. The trapezoidal block releases the squeeze on the fixed frame, making it easier for the staff to remove the filter, replace or clean it.

[0017] Preferably, a spike is fixedly connected to one side of the base plate, and the tip of the spike is away from the base plate.

[0018] The effect achieved by the above components is: by inserting the sharp spikes into the soil, the bottom plate is fixed to prevent the bottom plate from sliding against the ground.

DETAILED DESCRIPTION

[0029] Reference Figure 1-5As shown, this embodiment discloses an anti-corrosion gate valve, comprising a valve body 1 , a filtering device 2 is provided inside the valve body 1 , and auxiliary devices 3 are provided on both sides of the valve body 1 .

[0030] Reference Figure 1-5 As shown, the filtering device 2 includes a fixing ring 21, which is fixedly connected to the inside of the valve body 1. A fixing frame 22 is provided on one side of the fixing ring 21, and a filter screen 23 is fixedly connected to the inside of the fixing frame 22. Two symmetrical clips 25 are fixedly connected to one side of the fixing ring 21. A reserved hole 24 is provided in the fixing frame 22 corresponding to the clip 25. The size of the reserved hole 24 is adapted to the size of the clip 25. Grooves 26 are provided at both ends of the clip 25. The clip 25 is fixedly connected to a spring 27 by means of the groove 26, and one end of the spring 27 is fixedly connected to a trapezoidal block 28. When the filter screen 23 needs to be installed, the staff first moves the fixing frame 22, and the fixing frame 22 moves with the filter screen 23 toward the fixing ring 21. The clamp 25 on the fixing ring 21 is inserted into the reserved hole 24 of the fixing frame 22. At this time, the inclined surface of the trapezoidal block 28 on the clamp 25 is squeezed by the inner wall of the reserved hole 24, and the trapezoidal block 28 moves toward the inner direction of the groove 26. The spring 27 contracts. When the trapezoidal block 28 moves past the reserved hole 24, the fixing frame 22 fits the fixing ring 21 exactly. Under the action of the restoring force of the spring 27, the trapezoidal block 28 moves out of the groove 26 of the clamp 25, and the trapezoidal block 28 clamps the fixed frame 22, thereby achieving the effect of fixing the filter screen 23 in the fixed frame 22. The filter device 2 achieves the effect of fixing the filter screen 23, and the filter screen 23 is used to filter the fluid impurities inside the valve body 1, thereby preventing impurities in the fluid from sticking to the parts inside the valve body 1, thereby causing the valve body 1 to be corroded, thereby improving the service life of the valve body 1.

[0031] Reference Figure 1-5 As shown, a pull plate 29 is fixedly connected to the upper surface of the trapezoidal block 28. A stopper hole is defined in the clamping member 25 corresponding to the pull plate 29. The pull plate 29 is larger than the stopper hole. The pull plate 29 increases the contact area between the trapezoidal block 28 and the operator's hand, making it easier for the operator to move the trapezoidal block 28. The trapezoidal block 28 releases its pressure on the fixed frame 22, allowing the operator to remove the filter 23 for replacement or cleaning. A telescopic rod 210 is fixedly connected to one side of the trapezoidal block 28. One end of the telescopic rod 210 is fixedly connected to the inner wall of the groove 26. The provision of the telescopic rod 210 restricts the movement direction of the trapezoidal block 28, preventing it from rotating and improving its stability. A rubber seal 211 is fixedly connected to one side of the retaining ring 21. The seal 211 seals the gap between the retaining ring 21 and the fixed frame 22, preventing impurities from entering the interior of the valve body 1 through this gap.

[0032] Reference Figure 1-5 As shown, the auxiliary device 3 includes two symmetrical fixing plates 31, which are fixedly connected to the two sides of the valve body 1 respectively. The surface of the fixing plate 31 is threadedly connected to a screw 32, and one end of the screw 32 is rotatably connected to the bottom plate 33. When the height of the valve body 1 needs to be adjusted, the staff rotates the screw 32 on the fixing plate 31, and the screw 32 moves with the bottom plate 33. The bottom plate 33 contacts the ground and supports the valve body 1, and the height of the valve body 1 is changed. When the pipes on both sides of the valve body 1 are parallel to the connecting pipe, the staff stops rotating the screw 32. The effect of adjusting the height of the valve body 1 is achieved through the auxiliary device 3, avoiding stress on the pipes on both sides of the valve body 1, which may cause the pipes on both sides of the valve body 1 to separate from the connecting pipe.

[0033] Reference Figure 1-5 As shown, one end of the screw rod 32 is fixedly connected to a handle 36, and the arc surface of the handle 36 is fixedly connected to a number of protrusions. By providing the handle 36, the effect of facilitating the staff to rotate the screw rod 32 is achieved, which brings convenience to the staff in rotating the screw rod 32. A spike 34 is fixedly connected to one side of the base plate 33, and the tip of the spike 34 is away from the base plate 33. By inserting the spike 34 into the soil, the base plate 33 is fixed, and the base plate 33 is prevented from sliding with the ground. A limiting rod 35 is provided on the surface of the fixed plate 31, and one end of the limiting rod 35 is fixedly connected to the base plate 33. By providing the limiting rod 35, the effect of limiting the moving direction of the base plate 33 is achieved, thereby improving the stability of the movement of the base plate 33.

[0034] Working principle: When the filter screen 23 needs to be installed, the staff first moves the fixing frame 22, and the fixing frame 22 moves with the filter screen 23 toward the fixing ring 21. The clamp 25 on the fixing ring 21 is inserted into the reserved hole 24 of the fixing frame 22. At this time, the inclined surface of the trapezoidal block 28 on the clamp 25 is squeezed by the inner wall of the reserved hole 24, and the trapezoidal block 28 moves toward the inner direction of the groove 26. The spring 27 contracts. After the trapezoidal block 28 moves through the reserved hole 24, the fixing frame 22 fits the fixing ring 21 with the help of the sealing ring 211. At the same time, under the action of the restoring elastic force of the spring 27, the trapezoidal block 28 moves out of the groove 26 of the clamp 25, and the trapezoidal block 28 fixes the fixing frame 2 2 is stuck, achieving the effect of fixing the filter screen 23 in the fixed frame 22. When the filter screen 23 needs to be disassembled, the staff moves the pull plate 29, and the pull plate 29 moves with the trapezoidal block 28. When the trapezoidal block 28 completely enters the interior of the groove 26, the staff removes the fixed frame 22 from the fixed ring 21, achieving the effect of disassembling the filter screen 23. The filter device 2 achieves the effect of fixing the filter screen 23, and the filter screen 23 is used to filter the impurities in the fluid inside the valve body 1, thereby preventing the impurities in the fluid from sticking to the parts inside the valve body 1, thereby causing the valve body 1 to be corroded, thereby improving the service life of the valve body 1.

[0035] When the height of the valve body 1 needs to be adjusted, the staff rotates the screw 32 on the fixed plate 31 through the handle 36, and the screw 32 moves with the bottom plate 33. The bottom plate 33 contacts the ground with the help of the spikes 34 and supports the valve body 1. The height of the valve body 1 is changed. When the pipes on both sides of the valve body 1 are parallel to the connecting pipe, the staff stops rotating the screw 32, and the effect of adjusting the height of the valve body 1 is achieved through the auxiliary device 3, thereby avoiding the pipes on both sides of the valve body 1 from being subjected to force, which may cause the pipes on both sides of the valve body 1 to be separated from the connecting pipe.
