[0002] A gate valve is a device that controls the flow of water through opening and closing parts. The opening and closing parts of the gate valve are the gate plates, and the movement direction of the gate plates 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.

[0003] Chinese patent CN214888985U discloses a gate valve that is easy to dredge, including a valve body and a dredge component, the two ends of the valve body are respectively provided with a water inlet end and a water outlet end, a gate plate is vertically penetrated inside the valve body, a first fixing frame is vertically fixed to the position corresponding to the gate plate on the top surface of the valve body through a flange, a screw rod is vertically threaded through the top wall of the first fixing frame, the bottom end of the screw rod passes through the flange and the top wall of the valve body and is rotatably connected to the gate plate, and a rotating disk is horizontally fixed to the top end of the screw rod; a dredge component is arranged inside the valve body on the side of the gate plate near the water inlet end, and the dredge component is composed of a shell, a dredge rod and a spiral blade, the shell is horizontally placed inside the valve body, and a dredge rod is horizontally rotatably installed on one end wall of the shell near the gate plate, and a spiral blade is arranged on the outer wall of the dredge rod.

However, the contact area between the space inside the valve body and the dredging rod and the spiral blades is small, and the orientation of the dredging rod and the spiral blades needs to be constantly adjusted to adapt to more space inside the valve body that needs to be dredged, which is time-consuming and inefficient. For this reason, we propose a dredging structure and a gate valve. Summary of the invention

Since the overall coverage area of ​​the several brush clusters is large, the dredging efficiency is improved, and the problem that the contact area between the space inside the valve body and the dredging rod and the spiral blades is small in the above-mentioned scheme, and the orientation of the dredging rod and the spiral blades needs to be constantly adjusted to adapt to more space inside the valve body that needs to be dredged, which is time-consuming and inefficient.

[0010] Furthermore, the valve stem is threadedly connected to the fixed plate, and the bottom of the valve stem is movably engaged with the inside of the valve plate. The valve plate can be effectively opened and closed by rotating the valve stem, thereby controlling the flow of the fluid.

[0011] Furthermore, the first limiting mechanism includes a fixed block, and the upper end of the fixed block is connected to a support rod, the upper end of the support rod is connected to a T-shaped shaft rod, and the outer matching sleeve of the T-shaped shaft rod is provided with a stop rod.

[0012] Furthermore, the second limiting mechanism includes a slide groove, and a pull rod is engaged inside the slide groove, one side of the pull rod is connected to a clamping rod, and a spring is sleeved outside the clamping rod.

[0013] Furthermore, the pull rod forms an elastic structure through a spring and a slide groove, and the pull rod and the clamping rod are fixedly connected.

[0027] like Figure 1-2As shown, this embodiment provides a dredging structure and a gate valve, including a main body component 1, a dredging mechanism 2 is arranged on the left side of the surface of the main body component 1, and a group of first limiting mechanisms 3 are symmetrically arranged on the upper ends of the outer sides of the dredging mechanism 2, and a group of second limiting mechanisms 4 are symmetrically arranged on the lower ends of the dredging mechanism 2. The main body component 1 includes a valve body 101, and a flange seat 102 is connected to the middle part of the upper end of the valve body 101, and the upper end of the flange seat 102 is connected to the limiting seat 103, and the upper end of the limiting seat 103 is fixedly connected to a bracket 104, a valve stem 105 is penetrated inside the bracket 104, and a valve plate 106 is arranged at the bottom of the valve stem 105, and a fixing plate 107 is spanned inside the limiting seat 103, and the valve stem 105 and the fixing plate 107 are threadedly connected, and the bottom of the valve stem 105 is movably engaged with the inside of the valve plate 106. Since the valve stem 105 and the fixed plate 107 are threadedly connected, and the bottom of the valve stem 105 is movably engaged with the inside of the valve plate 106, the user can effectively open and close the valve plate 106 by rotating the valve stem 105, thereby controlling the on-off of the fluid. The dredging mechanism 2 includes a fixed groove frame 201, and the upper end of the fixed groove frame 201 is attached to the limit plate 202, the inner middle end of the limit plate 202 is penetrated by a rotating rod 203, and the outer side of the rotating rod 203 is fixed with a clamping plate 204, the bottom of the rotating rod 203 is connected to a first sealing plate 205, and the middle part of the lower end of the first sealing plate 205 is connected to a connecting rod 206, and the connecting rod The lower end of 206 is connected to a second sealing plate 207, and a plurality of brush clusters 208 are evenly distributed on the outer surface of the connecting rod 206. The card plate 204 is movably engaged with the inside of the limit plate 202, and the rotating rod 203 forms a rotating structure with the limit plate 202 through the card plate 204. When it is necessary to dredge the inside of the valve body 101, the limit plate 202 is pressed against the outer upper end surface of the fixed groove frame 201, and the limit plate 202 is limited by the first limiting mechanism 3. At this time, the first sealing plate 205 prevents the fluid from entering the fixed groove frame 201, and then the rotating rod 203 is rotated. The rotating rod 203 effectively drives the first sealing plate 205, the connecting rod 206, and the second sealing plate 207 to rotate, so that the plurality of brush clusters on the surface of the connecting rod 206 208 stirs and disperses the deposits on the water inlet side of the valve body 101. Since the overall coverage area of ​​the brush clusters 208 is large, the dredging efficiency is improved. The first limiting mechanism 3 includes a fixed block 301, and the upper end of the fixed block 301 is connected to a support rod 302, the upper end of the support rod 302 is connected to a T-shaped shaft rod 303, and the outer matching sleeve of the T-shaped shaft rod 303 is provided with a baffle rod 304. The baffle rod 304 is rotated along the T-shaped shaft rod 303 until the lower end surface of the baffle rod 304 is in contact with the upper end surface of the limiting plate 202, so as to limit the limiting plate 202. When the position of the limiting plate 202 needs to be adjusted, the baffle rod 304 is rotated along the T-shaped shaft rod 303 until the lower end surface of the baffle rod 304 is separated from the upper end surface of the limiting plate 202. Example

[0028] like Figure 3-4As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that the second limiting mechanism 4 includes a slide groove 401, and a pull rod 402 is engaged inside the slide groove 401, a clamping rod 403 is connected to one side of the pull rod 402, and a spring 404 is sleeved on the outside of the clamping rod 403. The pull rod 402 forms an elastic structure with the slide groove 401 through the spring 404, and the pull rod 402 and the clamping rod 403 are fixedly connected. During the dredging process, the clamping rod 403 is squeezed and received by the first sealing plate 205 inside the valve body 101, and the dredging work is completed. After completion, the rotating rod 203 is moved upward on the basis of the separation of the lower end surface of the blocking rod 304 from the upper end surface of the limiting plate 202 until the first sealing plate 205 is close to the upper end of the fixed groove frame 201. At this time, the second sealing plate 207 is located at the lower end of the fixed groove frame 201. Both sides of the second sealing plate 207 are provided with card grooves matching the card rod 403. Under the influence of the rebound force of the spring 404, the card rod 403 pops out and effectively engages with the inner side of the second sealing plate 207, thereby limiting the second sealing plate 207.

[0029] Step 1: Since the valve stem 105 is threadedly connected to the fixed plate 107 and the bottom of the valve stem 105 is movably engaged inside the valve plate 106, the user can effectively open and close the valve plate 106 by rotating the valve stem 105, thereby controlling the flow of the fluid.

[0030] Step 2. When it is necessary to dredge the inside of the valve body 101, place the limit plate 202 close to the outer upper surface of the fixed groove frame 201, and at the same time rotate the baffle rod 304 along the T-shaped shaft 303 until the lower end surface of the baffle rod 304 is in contact with the upper end surface of the limit plate 202 to limit the limit plate 202. At this time, the first sealing plate 205 prevents the fluid from entering the fixed groove frame 201, and then rotate the rotating rod 203. The rotating rod 203 effectively drives the first sealing plate 205, the connecting rod 206, and the second sealing plate 207 to rotate, so that the several brush clusters 208 on the surface of the connecting rod 206 stir and evacuate the deposits on the water inlet side of the valve body 101. Since the overall coverage of the several brush clusters 208 is large, the dredging efficiency is improved.

[0031] Step three, during the unblocking process, the locking rod 403 is squeezed and stored on the inner side of the valve body 101 by the first sealing plate 205. After the unblocking work is completed, the blocking rod 304 is rotated along the T-shaped shaft rod 303 until the lower end surface of the blocking rod 304 is separated from the upper end surface of the limit plate 202. At the same time, the rotating rod 203 is moved upward until the first sealing plate 205 is close to the upper end of the fixed groove frame 201. At this time, the second sealing plate 207 is located at the lower end of the fixed groove frame 201. The second sealing plate 207 has grooves matching the locking rod 403 on both sides. Under the influence of the rebound force of the spring 404, the locking rod 403 pops out and effectively engages with the inner side of the second sealing plate 207, thereby limiting the second sealing plate 207.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
