Description

Technical Field

[0001] The present invention relates to the field of mud valves, and particularly to a mud valve with a dredging and anti-blocking function. Background Art

[0002] In a mud conveying system, as a key control component, the performance of the mud valve directly affects the stability and efficiency of the entire system. Traditional mud valves often neglect the potential impact of impurities and particulate matters in the mud on the internal structure of the valve. After long-term use, it is easy to cause the valve to be blocked, affecting the normal flow of the mud, and even damaging the valve, increasing the maintenance cost and downtime.

[0003] To solve this problem, some mud valves with anti-blocking functions have emerged in the market. However, most of these valves adopt a simple filter screen structure. Although they can block large particle impurities to a certain extent, the filtering effect on fine particles is limited, and the filter screen is prone to blockage and difficult to clean and maintain. In addition, there are often problems such as poor sealing and loose bolts in the connection part of the valve, further increasing the risk of blockage and leakage. Summary of the Invention

[0004] The purpose of the present invention is to provide a mud valve with a dredging and anti-blocking function to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A mud valve with a dredging and anti-blocking function, including a mud valve body. Connecting pipes are fixed on both sides of the mud valve body. Flange plates are fixed at the ends of the connecting pipes. Bolt holes are formed on the surfaces of the flange plates. One end of the connecting pipe is inserted with a connecting sleeve. A plastic sleeve is inserted on the surface of the connecting sleeve. The plastic sleeve is inserted into the bolt hole. A metal mesh plate and two connecting rings two are arranged inside the connecting sleeve. The two connecting rings two are symmetrically distributed with respect to the metal mesh plate.

[0006] Preferably, the connecting sleeve is a "T"-shaped round pipe. A plurality of reserved holes are formed on the surface of the connecting sleeve. The reserved holes correspond to the bolt holes one by one. The plastic sleeve is a "T"-shaped round pipe. One end of the plastic sleeve is inserted and fixed in the reserved hole. The other end of the plastic sleeve penetrates through the bolt hole.

[0007] Preferably, a rubber ring is sleeved and fixed at one end of the plastic sleeve. The outer diameter of the rubber ring is larger than the aperture of the bolt hole.

[0008] Preferably, both the metal mesh plate and the connecting ring two are inserted into the installation ring. A through hole one is formed on the surface of the installation ring. A screw rod one is inserted into the through hole one. One end of the screw rod one is fixed on the surface of the connecting ring one. The connecting ring one is fixed inside the connecting sleeve. The other end of the screw rod one is sleeved and screwed with a nut one.

[0009] Preferably, there are multiple first perforations, and the multiple first perforations are circumferentially distributed with the inner ring opening of the mounting ring as the center. The inner diameter of the mounting ring is equal to the inner diameter of the first connecting ring.

[0010] Preferably, a second connecting ring is fixed to the inner ring surface of the mounting ring. Perforations are formed on the surfaces of the metal mesh plate and the metal mesh cover. A second screw is fixed to the surface of the second connecting ring. The second screw penetrates through the perforations on the surfaces of the metal mesh plate and the metal mesh cover, and a second nut is sleeved and screwed on one end of the second screw.

[0011] Preferably, there are multiple second screws, and the multiple second screws are circumferentially distributed with the inner ring opening of the second connecting ring as the center.

[0012] Preferably, the metal mesh cover is in the shape of an arc cover, and the protruding part of the metal mesh cover is away from the metal mesh plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The mud valve with the function of dredging and anti-blocking proposed by the present invention realizes the tight connection between the valve and the flange of the material pipeline by introducing the designs of the connecting sleeve and the plastic sleeve. The plastic sleeve not only serves as a temporary connection structure between the connecting sleeve and the flange, but also can be tightly clamped in the bolt hole under pressure when the bolt passes through, effectively preventing the bolt from loosening and falling off, and improving the stability and sealing performance of the connection. A filtering system composed of a metal mesh plate and a metal mesh cover is arranged inside the connecting sleeve, which can effectively filter out impurities and particulate matters in the mud and prevent them from entering the valve interior to cause blockage. The metal mesh cover is designed in an arc cover shape, which can disperse the filtered materials around, further reducing the risk of blockage. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a mud valve with a dredging and anti-blocking function, including a mud valve body 1. Both sides of the mud valve body 1 are fixedly provided with connecting pipes 2. The ends of the connecting pipes 2 are fixedly provided with flange plates 3. Bolt holes 4 are opened on the surfaces of the flange plates 3. One end of the connecting pipe 2 is inserted with a connecting sleeve 5. A plastic sleeve 7 is inserted on the surface of the connecting sleeve 5. The plastic sleeve 7 is inserted into the bolt hole 4. The connecting sleeve 5 is a "T"-shaped round pipe. A plurality of reserved holes 6 are opened on the surface of the connecting sleeve 5. The reserved holes 6 and the bolt holes 4 correspond one by one. The plastic sleeve 7 is a "T"-shaped round pipe. One end of the plastic sleeve 7 is inserted and fixed in the reserved hole 6. The other end of the plastic sleeve 7 penetrates through the bolt hole 4. A rubber ring 8 is sleeved and fixed at one end of the plastic sleeve 7. The outer diameter of the rubber ring 8 is larger than the aperture of the bolt hole 4.

[0025] After inserting one end of the connecting sleeve 5 into the connecting pipe 2, the plastic sleeve 7 is inserted into the corresponding bolt hole 4. When the flange of the material pipeline leans against one side of the connecting sleeve 5, after passing the bolt through the hole on the flange surface and the plastic sleeve 7, the bolt is tightened. The plastic sleeve 7 not only serves as a temporary connection structure between the connecting sleeve 5 and the flange plate 3, but also, after the bolt passes through the plastic sleeve 7, the plastic sleeve 7 is pressed tightly and stuck in the bolt hole 4 to achieve the anti-loosening effect on the bolt.

[0026] Inside the connecting sleeve 5, there are a metal mesh plate 14 and a second connecting ring 15. There are two second connecting rings 15, which are symmetrically distributed with respect to the metal mesh plate 14. Both the metal mesh plate 14 and the second connecting ring 15 are inserted into the mounting ring 10. On the surface of the mounting ring 10, there are first through holes 11. Inside the first through holes 11, there are first screws 12 inserted. One end of the first screw 12 is fixed on the surface of the first connecting ring 9, and the first connecting ring 9 is fixed inside the connecting sleeve 5. The other end of the first screw 12 is sleeved and screwed with a first nut 13; there are multiple first through holes 11, and the multiple first through holes 11 are circumferentially distributed with the inner ring opening of the mounting ring 10 as the center. The inner diameter of the mounting ring 10 is equal to the inner diameter of the first connecting ring 9; on the inner ring surface of the mounting ring 10, there is a second connecting ring 15 fixed. On the surfaces of both the metal mesh plate 14 and the metal mesh cover 16, there are second through holes 17. On the surface of the second connecting ring 15, there is a second screw 18 fixed. The second screw 18 passes through the second through holes 17 on the surfaces of the metal mesh plate 14 and the metal mesh cover 16, and one end of the second screw 18 is sleeved and screwed with a second nut 19; there are multiple second screws 18, and the multiple second screws 18 are circumferentially distributed with the inner ring opening of the second connecting ring 15 as the center; the metal mesh cover 16 is in the shape of an arc-shaped cover, and the protruding part of the metal mesh cover 16 is away from the metal mesh plate 14.

[0027] The metal mesh plate 14 and the metal mesh cover 16 achieve the filtering effect on the conveyed material, and the metal mesh cover 16 is in the shape of an arc cover, which is convenient for dispersing the filtered material to the surroundings and reducing the hidden danger of blockage inside the connecting pipe 2; when it is necessary to clean or replace the metal mesh plate 14 and the metal mesh cover 16, remove the connecting sleeve 5 from the connecting pipe 2, then loosen the first nut 13, pull the mounting ring 10 out of the first screw 12, then loosen the second nut 19, and pull the metal mesh plate 14 and the metal mesh cover 16 out of the second screw 18.

[0028] The detailed usage process of the mud valve with the function of dredging and preventing blockage is as follows:

[0029] The wire mesh plate 14 and the second connecting ring 15 are inserted into the mounting ring 10. The mounting ring 10 is fixed to the first connecting ring 9 using the first screw 12 and the first nut 13, ensuring that the mounting ring 10 and the first connecting ring 9 are coaxial and closely fitted. Place the wire mesh cover 16 on the wire mesh plate 14, and use the second screw 18 and the second nut 19 to fix the wire mesh plate 14, the wire mesh cover 16 and the second connecting ring 15 together. Fix the connecting pipe 2 on both sides of the mud valve body 1, ensuring a firm connection. Fix the flange 3 at the end of the connecting pipe 2, ensuring that the flange 3 and the connecting pipe 2 are coaxial and closely fitted. Insert and fix one end of the plastic sleeve 7 into the reserved hole 6 on the surface of the connecting sleeve 5. Set a rubber ring 8 on the other end of the plastic sleeve 7, ensuring that the outer diameter of the rubber ring 8 is larger than the aperture of the bolt hole 4. Insert one end of the connecting sleeve 5 into the connecting pipe 2, ensuring that the connecting sleeve 5 and the connecting pipe 2 are coaxial and closely fitted. Adjust the position of the connecting sleeve 5 so that the plastic sleeve 7 is inserted into the corresponding bolt hole 4. Place the flange of the material pipeline to be connected against one side of the connecting sleeve 5. Use bolts to pass through the holes on the surface of the flange and the plastic sleeve 7, ensuring that the bolts can pass through smoothly and reach the other side of the flange. Tighten the bolts to ensure a firm connection between the flange and the connecting sleeve 5. After ensuring that all the connecting components are firmly installed, start the mud valve to start conveying materials. Regularly monitor the operating status of the mud valve and check for any clogging or leakage. Regularly check the wear conditions of the plastic sleeve 7 and the rubber ring 8, and replace the severely worn components in a timely manner. When it is found that there is a clogging inside the mud valve or it needs to be cleaned, first close the mud valve to cut off the material conveyance. Remove the connecting sleeve 5, loosen the first nut 13 and the second nut 19, and pull the wire mesh plate 14 and the wire mesh cover 16 away from the second screw 18. Clean the clogging on the wire mesh plate 14 and the wire mesh cover 16 to ensure that the filtering structure is unobstructed. Check and clean the debris and dirt inside the connecting sleeve 5 and the connecting pipe 2.
