Description

Technical Field

[0001] The utility model relates to the technical field of slurry valves, in particular to a novel slurry valve. Background Art

[0002] The slurry valve currently used in the papermaking, pharmaceutical, dye and chemical industries on the market is an integrated operating tool. Its disadvantages are: the disassembly and replacement of internal parts are cumbersome and not corrosion-resistant, making the valve body more susceptible to damage. At the same time, it does not have good sealing performance, making the slurry more prone to leakage, and it is easy to make rotational motion during operation, which seriously affects the normal operation of the valve body. It can no longer meet people's needs. For this reason, we propose a new type of slurry valve. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a new type of slurry valve with novel design and simple structure, which is convenient for the staff to disassemble and assemble the valve body. At the same time, it has a good sealing effect, so that the slurry is not easy to leak, and can provide good protection for the packing and the valve body, making it difficult to be damaged. The practical performance of the slurry valve is greatly improved to solve the problems raised in the above-mentioned background technology.

[0004] The technical problem solved by the utility model is achieved by the following technical solutions:

[0005] A new type of slurry valve comprises a valve body, a valve right body and a valve left body. One side of the valve body is conductively connected to the valve right body, the bottom end of the valve body is conductively connected to the valve left body, a valve seat is arranged between the valve body and the valve left body, a valve disc is arranged on the top of the valve seat, a sealing groove is arranged on the top of the valve seat, a guide groove is arranged on one side of the sealing groove, sealing protrusions are arranged at both ends of the bottom of the valve disc, a valve cover is fixedly connected to the top of the valve body, a packing is arranged inside the valve cover, packing pads are arranged at both upper and lower ends of the packing, a packing gland is arranged on the top of the packing pad, and a valve stem is arranged inside the packing.

[0006] Furthermore, a fixing frame is fixedly connected to the top of the valve cover, and limiting plates are fixedly connected to both side walls of the fixing frame. Anti-rotation plates are slidably connected between the limiting plates, and limiting pins are arranged inside the anti-rotation plates.

[0007] Furthermore, a No. 1 fixing screw is arranged between the valve cover and the valve body, a No. 2 fixing screw is arranged inside the packing gland, and the packing gland is fixedly connected to the valve cover through the No. 2 fixing screw, and a hand wheel is rotatably connected to the top of the fixing frame.

[0008] Furthermore, a valve disc is fixedly connected to the bottom end of the valve stem, a hand wheel is threadedly connected to the top end of the valve stem, and the valve stem is slidably connected to the packing.

[0009] Furthermore, the anti-rotation plate is fixedly connected to the valve stem via a limit pin, the anti-rotation plate is slidably connected to the fixing frame via a limit plate, and the filler is a filler made of graphite.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Through the combination of the valve seat and the valve disc, the slurry inside the left body of the valve can be well blocked, so that the slurry will no longer flow inside the valve body when the valve body is closed, and after the valve is closed, the sealing protrusion will be located inside the sealing groove, thereby effectively improving the sealing effect between the valve seat and the valve disc, making it difficult for the slurry to leak, further improving the sealing ability of the valve body, and being more practical.

[0012] 2. The guide groove has a good guide effect, which can effectively reduce the impact force of the slurry on the valve seat, prevent the valve seat from being deformed under the impact of high-speed flow slurry for a long time, and avoid affecting the sealing effect between the valve seat and the valve disc. At the same time, the top of the valve body is an arc surface, which can effectively reduce the impact force of the slurry on the top of the valve body, making the valve body less likely to be damaged, which is more practical.

[0013] 3. The packing made of graphite can clear the liquid on the surface of the valve stem to prevent the liquid from leaking from the top of the valve cover and affecting the sealing effect of the valve body. It is more practical. Through the combination of the packing gland and the packing pad, the packing can be well pressed to prevent it from moving, thereby improving the stability of the packing during operation.

[0018] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below with reference to specific illustrations.

[0019] like Figures 1 to 4As shown, by combining the right valve body 2 and the left valve body 3, the valve body 1 can be connected to the external material pipe, so that the valve body 1 can work, wherein the combination of the valve seat 4 and the valve disc 5 can well block the slurry inside the left valve body 3, so that the slurry will no longer flow inside the valve body 1 when the valve body 1 is closed, and after the valve is closed, the sealing protrusion 8 will be located inside the sealing groove 6, thereby effectively improving the sealing effect between the valve seat 4 and the valve disc 5, so that the slurry is not easy to leak, further improving the sealing ability of the valve body 1, which is more practical. When the valve body 1 is needed to work, the hand wheel 20 can be rotated left and right at the same time, so as to drive the valve stem 13 to move up and down, so that the slurry inside the left valve body 3 can flow into the valve body 1, wherein the valve seat 4 is arranged with an inclined guide groove 7, which has a good guide effect, thereby effectively reducing the impact force of the slurry on the valve seat 4, and preventing the valve seat 4 from being deformed under the impact of high-speed flowing slurry for a long time. The packing 10 made of graphite can clear the liquid on the surface of the valve stem 13 to prevent the liquid from leaking from the top of the valve cover 9, thus avoiding affecting the sealing effect of the valve body 1, which is more practical. The packing gland 12 and the packing pad 11 can be combined to press the packing 10 well, so that it is not easy to move, thereby improving the stability of the packing 10 during operation, and the packing gland 12 can be easily fixed by the No. 2 fixing screw 14, which is more practical. The anti-rotation plate 18 and the limit plate 17 can be combined to make the valve stem 13 move and drive the anti-rotation plate 18 to slide well inside the fixing frame 16, so that the anti-rotation plate 18 can prevent the valve stem 16 from rotating when sliding, which is more practical. In addition, the valve cover 9 is connected to the valve body 1 by the No. 1 fixing screw 15, which is convenient for the staff to disassemble and assemble it, so as to replace the internal parts of the valve body 1.
