Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an anti-clogging structure for a large-diameter regulating shut-off valve. Background Technology

[0002] Large-diameter regulating shut-off valves are widely used in industries such as petroleum, chemical, natural gas, water treatment, and power. They are used to control the shut-off and connection of high-flow fluids and are indispensable fluid control equipment in industrial production.

[0003] Existing large-diameter regulating shut-off valves are prone to internal blockage due to the entry of foreign particles in the medium, which affects their efficiency. Therefore, an anti-blockage structure for large-diameter regulating shut-off valves is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an anti-clogging structure for a large-diameter regulating shut-off valve. This structure provides an anti-clogging mechanism for the valve body, allowing the medium entering the valve body to be filtered. This effectively prevents foreign matter of particle size from entering the valve body and causing blockage. Furthermore, it allows for the rapid discharge of accumulated dirt without disassembly, greatly increasing the stability of the shut-off valve during long-term use.

[0005] The technical solution adopted by this utility model to solve its technical problem is an anti-clogging structure for a large-diameter regulating shut-off valve, including an anti-clogging and sewage discharge mechanism installed at the feed end of the large-diameter regulating shut-off valve body.

[0006] The anti-clogging and sewage discharge mechanism includes a sewage collection box, side sealing plates, and a bottom cover plate. The sewage collection box has an inlet and an outlet on both sides, and two sets of side sealing plates are provided inside the sewage collection box and cover the inlet and outlet respectively.

[0007] By adopting the above technical solution and setting up an anti-clogging and sewage discharge mechanism, an anti-clogging mechanism is provided for the body of the large-diameter regulating shut-off valve. This allows the medium entering the large-diameter regulating shut-off valve body to be filtered, effectively preventing foreign objects of different particle sizes from entering the large-diameter regulating shut-off valve body and causing potential blockages. Furthermore, without disassembly, the accumulated dirt can be quickly discharged, greatly increasing the stability of the shut-off valve during long-term use.

[0008] Specifically, the inlet and outlet are respectively connected to an inlet flange and an outlet flange. The bottom of the outlet flange is provided with a ramp to facilitate the discharge of solid material to the bottom of the collection box. The end of the outlet flange away from the collection box is connected to a metal filter screen, and the outlet flange is connected to the inlet end of the large-diameter regulating shut-off valve body.

[0009] By adopting the above technical solution, through the setting of metal filter screen and ramp, the metal filter screen can facilitate the filtration of the medium entering the large-diameter regulating shut-off valve body, and prevent large particles of foreign matter from entering the large-diameter regulating shut-off valve body and causing internal blockage. The ramp is beneficial for foreign matter in the discharge flange to fall back into the sludge collection box by means of the slope.

[0010] Specifically, the sewage collection box is equipped with a cross rod, and an electric push rod is installed on the top of the sewage collection box. The output end of the electric push rod is connected to the top of the cross rod, and the two ends of the cross rod are respectively connected to the two sets of side sealing plates.

[0011] Specifically, the bottom of the waste collection box is provided with a waste discharge port, the lower cover plate is placed on the bottom of the waste discharge port, and the bottom of the cross rod is connected to the top of the lower cover plate;

[0012] The top of the lower cover plate is configured as a cone shape for foreign object discharge.

[0013] By adopting the above technical solution, through the setting of electric push rod and cross rod, after the cross rod of the lower part of the electric push rod, two sets of side sealing plates can temporarily block the feed port and the discharge port. At the same time, the lower cover plate moves away from the blockage of the discharge port, allowing foreign objects in the sludge collection box to be discharged to the outside. Through the conical setting of the top of the lower cover plate, foreign objects on the lower cover plate can slide off better with the help of the conical ramp.

[0014] Specifically, the bottom of the waste collection box is provided with a rubber sealing ring for sealing with the lower cover plate.

[0015] By adopting the above technical solution, and by setting a lower cover plate with a rubber sealing ring on the top, after the lower cover plate covers the bottom of the waste discharge port, the lower cover plate contacts the bottom of the waste collection box, and the rubber sealing ring can further improve the sealing effect between the lower cover plate and the waste collection box.

[0016] The beneficial effects of this utility model are as follows: By setting up an anti-clogging and sewage discharge mechanism, an anti-clogging mechanism is provided for the body of the large-diameter regulating shut-off valve, so that the medium entering the body of the large-diameter regulating shut-off valve can be filtered, effectively preventing foreign objects of different particle sizes from entering the body of the large-diameter regulating shut-off valve and causing blockage. Moreover, the accumulated dirt can be quickly discharged without disassembly, which greatly increases the stability of the shut-off valve in long-term use and solves the problem that existing large-diameter regulating shut-off valves are prone to internal blockage caused by foreign objects of different particle sizes in the medium, which affects the efficiency of use.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-4 As shown, the anti-clogging structure of the large-diameter regulating shut-off valve of this utility model includes an anti-clogging and sewage discharge mechanism 2 installed at the feed end of the large-diameter regulating shut-off valve body 1.

[0025] The anti-blockage sewage discharge mechanism 2 includes a sewage collection box 21, a side sealing plate 28, and a lower cover plate 210. The sewage collection box 21 has an inlet 22 and an outlet 23 on both sides. The side sealing plate 28 is provided in two sets and is located on both sides inside the sewage collection box 21, covering the inlet 22 and the outlet 23 respectively.

[0026] The present invention also includes a feed flange 24 and a discharge flange 25 connected to the feed port 22 and the discharge port 23 respectively. The bottom of the discharge flange 25 is provided with a ramp 26 to promote the discharge of solid material to the bottom of the collection box 21. The end of the discharge flange 25 away from the collection box 21 is connected to a metal filter screen 27, and the discharge flange 25 is connected to the feed end of the large-diameter regulating shut-off valve body 1.

[0027] When in use, the metal filter screen 27 and the ramp 26 are used to facilitate the filtration of the medium entering the large-diameter regulating shut-off valve body 1, preventing large particles of foreign matter from entering the large-diameter regulating shut-off valve body 1 and causing internal blockage. The ramp 26 is beneficial for foreign matter in the discharge flange 25 to fall back into the sludge collection box 21 by means of the slope.

[0028] This utility model also includes a cross rod 211 provided inside the sewage collection box 21, an electric push rod 213 installed on the top of the sewage collection box 21, the output end of the electric push rod 213 being connected to the top of the cross rod 211, and the two ends of the cross rod 211 being connected to the two sets of side sealing plates 28 respectively.

[0029] This utility model also includes a waste discharge port 29 at the bottom of the waste collection box 21, a lower cover plate 210 covering the bottom of the waste discharge port 29, and the bottom of the cross rod 211 connected to the top of the lower cover plate 210.

[0030] The top of the lower cover plate 210 is configured as a cone shape for foreign object discharge.

[0031] In use, based on the electric push rod 213 and the cross rod 211, after the electric push rod 213 and the cross rod 211, the two sets of side sealing plates 28 can temporarily block the feed inlet 22 and the discharge outlet 23. At the same time, the lower cover plate 210 leaves the blockage of the discharge outlet 29, allowing foreign objects in the sludge collection box 21 to be discharged to the outside. Through the conical shape of the top of the lower cover plate 210, foreign objects on the lower cover plate 210 can slide off better with the help of the conical ramp.

[0032] This utility model also includes a rubber sealing ring 212 at the bottom of the sewage collection box 21 for sealing with the lower cover plate 210.

[0033] In use, the collection box 21 with a rubber sealing ring 212 at the bottom is used. After the lower cover plate 210 covers the bottom of the discharge port 29, the lower cover plate 210 contacts the bottom of the collection box 21. The rubber sealing ring 212 can further improve the sealing effect between the lower cover plate 210 and the collection box 21.

[0034] In use, the output end of the large-diameter regulating shut-off valve body 1 and the feed flange 24 of the anti-clogging and sewage discharge mechanism 2 are connected to the required pipeline system. Power is supplied to the electrical mechanism by the power supply components around the application site. During operation, the anti-clogging and sewage discharge mechanism 2 acts as a pre-processor for the large-diameter regulating shut-off valve body 1, filtering the medium entering the valve body 1. This effectively intercepts larger particles, reducing the risk of blockage during subsequent use. During normal use, the electric push rod 213 pulls up the cross rod 211, preventing the side sealing plate 28 from blocking the feed inlet 22 and the discharge outlet 23. Meanwhile, the lower cover plate 210 seals the bottom of the discharge port 29. When discharge is required after a period of use, the two sets of side sealing plates 28 can be moved down by the electric push rod 213 and the cross rod 211, which can temporarily seal the feed port 22 and the discharge port 23. At the same time, the lower cover plate 210 moves away from the discharge port 29, allowing foreign objects in the sludge collection box 21 to be discharged. The discharged foreign objects are collected by workers through containers and then processed separately. After the discharge is completed, the electric push rod 213 pulls back the cross rod 211, so that the feed port 22 and the discharge port 23 quickly come into contact and close, and the discharge port 29 is closed again. The operation is simple and the use is flexible and convenient.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
