Description

Technical Field

[0001] This utility model belongs to the field of gate valves, specifically relating to an improved stainless steel soft-seal gate valve. Background Technology

[0002] Gate valves are devices used in fluid systems to control the direction, pressure, and flow rate of fluids. They are devices that allow fluids in piping and equipment to flow or stop and control their flow rate.

[0003] Chinese patent CN221958177U discloses a gate valve, which includes a valve body and a gate. Sealing portions are arranged around the inlet and outlet of the valve body. A protrusion is provided at the bottom of the cavity within the valve body, and a pressure-resistant inclined surface is provided on the protrusion facing both the inlet and outlet. A groove is provided at the bottom of the gate, dividing the gate into a first gate and a second gate. When the gate moves towards the protrusion, the protrusion can insert into the groove. The first and second gates respectively abut against the two pressure-resistant inclined surfaces and can slide along the inclined surfaces. The pressure-resistant inclined surfaces can apply pressure to the first and second gates, causing them to press against the sealing portions. This gate valve can apply lateral pressure to the first and second gates, ensuring they are tightly pressed against the sealing portions, thus improving the sealing effect and reliability. Simultaneously, it prevents impurities from settling at the bottom of the valve body, allowing the gate to move downwards and ensure the gate valve can close normally.

[0004] However, this technical solution is inconvenient to adjust the height of the gate in the valve body, and the adjusting rod does not have an anti-reverse function. Therefore, there is an urgent need for an improved stainless steel soft-seal gate valve. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, such as the inconvenience of adjusting the height of the gate plate in the valve body and the lack of anti-reverse function of the adjusting rod, thereby realizing an improved stainless steel soft-seal gate valve.

[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is: an improved stainless steel soft-seal gate valve, comprising a hollow valve body, a valve cover fixedly connected to the valve body, a support frame fixedly installed on the upper side of the valve cover, a gate plate sealed and inserted into the valve body, an adjusting component connected to the upper side of the gate plate for adjusting the height position of the gate plate in the valve body, an adjusting rod connected to the upper end of the adjusting component, the adjusting rod being rotatably set with the support frame, and an anti-reverse rotation component installed on the upper side of the adjusting rod for preventing the adjusting rod from rotating in the opposite direction.

[0007] Specifically, the adjusting component includes a movable plate detachably connected to the upper side of the gate plate, a sleeve fixedly connected to the upper side of the movable plate, an adjusting screw threadedly connected to the inner side of the sleeve, and an adjusting rod fixedly set on the upper side of the adjusting screw.

[0008] Specifically, the anti-reverse component includes an assembly plate detachably connected to the upper side of the support frame. A hollow fixed cylinder is fixedly installed on the upper side of the assembly plate. Three movable rods distributed at 120-degree angles are inserted into the upper circumference of the fixed cylinder. A lower ratchet is fixedly connected to the upper end of the movable rod. A spring is fixedly installed between the lower ratchet and the fixed cylinder. An upper ratchet is engaged with the upper side of the lower ratchet. The upper ratchet is fixedly installed with the adjusting rod.

[0009] Specifically, the valve cover has symmetrically opened sliding grooves on the middle side, and a sliding rod is inserted into the inner side of the sliding groove. The sliding rod is fixedly set with the sleeve.

[0010] Specifically, flanges are fixedly installed at both ends of the valve cover opening, and rubber ring grooves are opened on the end face of the flange away from the valve body.

[0011] Specifically, the movable plate is fixedly connected to the gate plate by bolts and nuts.

[0012] Specifically, the adjusting rod has a guide hole on its side, which extends downward into the adjusting screw. The adjusting screw has at least two lubrication holes on its upper side, and both lubrication holes are connected to the guide hole.

[0013] Specifically, a rotating handle is fixedly connected to the upper side of the adjusting rod.

[0014] Compared with the prior art, the improved stainless steel soft-seal gate valve of this utility model has at least the following beneficial effects:

[0015] This utility model, through the cooperation of the adjusting component with the valve body and adjusting rod, facilitates the adjustment of the height position of the gate plate in the valve body, thereby facilitating the blocking and flow of fluid in the external pipeline.

Detailed Implementation

[0021] The improved stainless steel soft-seal gate valve of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] This embodiment discloses an improved stainless steel soft-seal gate valve, such as... Figure 1-4 As shown, the valve includes a hollow valve body 1, a valve cover 4 fixedly connected to the valve body 1, a support frame 3 fixedly installed on the upper side of the valve cover 4, a gate 16 sealed and inserted inside the valve body 1, an adjusting component connected to the upper side of the gate 16 for adjusting the height position of the gate 16 inside the valve body 1, an adjusting rod 18 connected to the upper end of the adjusting component, the adjusting rod 18 being rotatably set with the support frame 3, and an anti-reverse component installed on the upper side of the adjusting rod 18 for preventing the adjusting rod 18 from rotating in the opposite direction.

[0024] The adjusting component includes a movable plate 5 detachably connected to the upper side of the gate plate 16, a sleeve 6 fixedly connected to the upper side of the movable plate 5, an adjusting screw 7 threadedly connected to the inner side of the sleeve 6, and an adjusting rod 18 fixedly set on the upper side of the adjusting screw 7.

[0025] The anti-reverse component includes an assembly plate 15 detachably connected to the upper side of the support frame 3. A hollow fixed cylinder is fixedly installed on the upper side of the assembly plate 15. Three movable rods 14, distributed at 120-degree angles, are inserted into the upper circumference of the fixed cylinder. A lower ratchet 12 is fixedly connected to the upper end of each movable rod 14. A spring 13 is fixedly installed between the lower ratchet 12 and the fixed cylinder. An upper ratchet 11 is meshed with the upper side of the lower ratchet 12. The upper ratchet 11 is fixedly installed with an adjusting rod 18. Through the meshing connection between the upper ratchet 11 and the lower ratchet 12, the adjusting rod 18 can rotate in one direction. When it is necessary to release the rotation, the adjustment rod 18 can rotate in one direction. When the adjusting rod 18 rotates in one direction, the lower ratchet 12 moves downward. Due to the insertion of multiple movable rods 14 and fixed cylinders, the lower ratchet 12 disengages from the upper ratchet 11 during its downward movement. This allows for free adjustment of the reverse direction of the adjusting rod 18. When the lower ratchet 12 is released, it returns to its original position under the force of the spring 13, thus engaging with the upper ratchet 11. This prevents the operator from accidentally opening the valve body 1 and allows the operator to quickly identify the direction of adjustment of the adjusting rod 18. It also serves as a foolproof mechanism.

[0026] The valve cover 4 has symmetrically opened sliding grooves on the middle side, and a sliding rod 8 is inserted into the inner side of the sliding groove. The sliding rod 8 is fixedly set with the sleeve 6, which facilitates the free movement of the sleeve 6 up and down, thereby making it convenient to adjust the position of the gate 16 at different heights inside the valve body 1.

[0027] Flanges 2 are fixedly installed at both ends of the valve cover 4 opening. Rubber ring grooves are provided on the end face of the flange 2 away from the valve body 1. These rubber ring grooves are used to place matching sealing rubber rings.

[0028] The movable plate 5 is fixedly connected to the gate plate 16 by bolts and nuts, thereby facilitating the fixing and disassembly of the gate plate 16 on the movable plate 5.

[0029] The adjusting rod 18 has a guide hole 10 on its side, which extends downward into the adjusting screw 7. The adjusting screw 7 has at least two lubrication holes 17 on its upper side, and the lubrication holes 17 are all connected to the guide hole 10.

[0030] A rotating handle 9 is fixedly connected to the upper side of the adjusting rod 18. By rotating the rotating handle, the angle of the adjusting rod 18 can be adjusted, thereby adjusting the height position of the gate plate 16 inside the valve body 1.

[0031] In use, this utility model is sealed to the external pipeline through the flanges 2 at both ends of the valve cover 4 opening. When the external pipeline needs to be sealed, the rotating handle 9 is rotated in the forward direction to facilitate the rotation of the adjusting rod 18. Then, through the transmission of the adjusting component, the height position of the gate 16 inside the valve body 1 is adjusted, so that the passage of the valve body 1 can be blocked by the gate 16, thereby achieving the function of blocking the flow of fluid in the existing pipeline. When it is necessary to form a passage for the fluid in the external pipeline, the unidirectional rotation of the adjusting rod 18 needs to be released. By moving the lower ratchet 12 downward, due to the insertion of the fixing cylinders of multiple movable rods 14, the lower ratchet 12 disengages from the upper ratchet 11 during the downward movement. At this time, it is convenient to freely adjust the reverse rotation of the adjusting rod 18, and further adjust the position of the gate 16 away from the bottom of the inner side of the valve body 1, so as to facilitate the formation of a passage for the fluid in the external pipeline.
