Description

Technical Field

[0001] This utility model relates to the field of mining valve technology, specifically to an anti-clogging mining valve. Background Technology

[0002] Mining valves are a special type of valve designed and manufactured specifically for the harsh working conditions of the mining industry. They do not refer to a single valve type, but rather to a comprehensive term encompassing various valve types and applications. Their core task is to control and regulate the flow of various fluids in the mining production system to ensure safe and efficient production. They are characterized by high strength and wear resistance, excellent corrosion resistance, and reliable sealing performance. Anti-clogging mining valves are a special type of valve designed specifically to solve the problem of valves being unable to close or open properly due to the deposition, entanglement, and jamming of solid particles in mining fluids. Existing anti-clogging mining valves require the installation of a filter screen at the mud inlet on the left side of the valve to intercept large particles. When the filter screen needs to be cleaned or replaced, the entire valve needs to be disassembled for cleaning and replacement. Existing anti-clogging mining valves of this type have the following problems: When using anti-clogging mining valves, cleaning and replacing the valves requires disassembling the entire valve, which is a cumbersome maintenance process, causes long downtime, and affects the continuity of production. Therefore, we propose an anti-clogging mining valve. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This embodiment provides a technical solution: an anti-clogging mining valve, including a valve body 1 and an anti-clogging mechanism 2. (The upper end of the valve body 1 is provided with a valve stem, and a rotating wheel is fixedly connected to the upper end of the valve stem. The valve body 1 is provided with a ball and a valve seat. The valve stem is driven by rotating the handwheel, and the ball is driven by rotating the valve stem. The circular through hole on the ball is completely aligned with the pipeline flow channel. The medium flows along the through hole without obstruction and the flow resistance is extremely small. When the ball rotates 90°, the through hole is completely offset from the pipeline flow channel. The solid part of the ball is tightly attached to the valve seat to block the flow of the medium.) A drain pipe 5 is provided at the drain port on the left side of the outer surface of the valve body 1. A cap 6 is threadedly connected to the right side of the lower end of the drain pipe 5. Anti-clogging mechanism 2 includes a circular block 21, a filter screen 22, a sealing ring 23, a pressure block 24, a bracket 25, and guide rods 26. A circular block 21 is connected in series on the left side of the valve body 1. An installation groove is provided inside the circular block 21, and the filter screen 22 is installed inside the installation groove. A bracket 25 is provided on the outer surface of the left side of the valve body 1. Guide rods 26 are slidably connected to the sliding holes at the upper end of the bracket 25. A pressure block 24 is fixedly connected between the lower ends of the guide rods 26. The pressure block 24 is inserted into the opening at the upper end of the circular block 21. A sealing ring 23 is provided between the rectangular wall formed by the lower end of the pressure block 24 and the inner wall of the installation groove and the outer wall of the filter screen 22. The anti-clogging mechanism 2 also includes a screw 27, a cylinder 28, and an internal threaded ring 29. The cylinder 28 is located at the upper end of the bracket 25. The upper end of 28 is rotatably connected to an internally threaded ring 29, and the internal thread of the internally threaded ring 29 is connected to a screw 27. (A rigid tube longer than the screw 27 can be installed on the upper end of the protective cover 32. The rigid tube will be sleeved on the outside of the screw 27 on the upper part of the protective cover 32. The rigid tube will protect the upper part of the protective cover 32, prevent dust from entering the interior of the screw 27, and ensure the sealing and lubrication of the screw 27.) The lower end of the screw 27 is fixedly connected to the upper end of the pressure block 24. The system also includes an adjustment assembly 3, which includes a worm gear 31, a protective cover 32, and a worm 33. The protective cover 32 is located on the upper end of the bracket 25. The worm gear 31 is fixedly sleeved on the outer surface of the internally threaded ring 29. The worm 33 is rotatably connected between the front and rear inner walls of the protective cover 32. The worm gear 31 meshes with the worm 33. The adjusting assembly 3 also includes an adjusting wheel 34, which is fixedly connected to the front end of the worm 33. A bellows 4 is fixedly connected between the upper end of the pressure block 24 and the top wall of the bracket 25. The bellows 4 is sleeved on the outside of the screw 27 on the lower side of the top wall of the bracket 25. (The bellows 4 protects the screw 27 on the lower side of the top wall of the bracket 25, preventing dust from entering the interior of the screw 27 and ensuring the sealing and lubrication of the screw 27.) The sealing ring 23 is a rubber sealing ring, and the bellows 4 is a nylon bellows. When using the anti-clogging mining valve, first, the sealing ring 23 is sleeved on the outer surface of the filter screen 22, and then the whole assembly of the sealing ring 23 and the filter screen 22 is inserted into the installation groove. The spring of the sealing ring 23... The gap can be filled to ensure that the slurry cannot bypass the gap between the filter screen 22 and the mounting groove and flow into the valve body. This ensures that all slurry is filtered by the filter screen 22, preventing unfiltered impurities from bypassing the filter screen 22 and clogging the valve body. Next, the adjusting wheel 34 is rotated, which drives the worm 33 to rotate. The worm 33 meshes with the worm wheel 31, which drives the internal threaded ring 29 to rotate around the cylinder 28. The internal threaded ring 29 is threadedly connected to the screw 27, and the lower end of the screw 27 is fixed to the pressure block 24. The pressure block 24 is guided by the guide rod 26 and the sliding hole of the bracket 25, restricting the pressure block 24 to move only in the vertical direction to prevent deviation. The pressure block 24 is inserted into the opening at the upper end of the circular block 21, pressing the filter screen 22 tightly into the mounting groove, while simultaneously squeezing the rubber sealing ring 23 to achieve a seal.Ensure that the filter screen 22 is not loose or leaking during filtration. (The filter screen 22 and sealing ring 23 need to be replaced and cleaned regularly to prevent clogging and ensure the flow of the filter screen 22. The sealing ring 23 needs to be replaced regularly to avoid loss of sealing performance after prolonged use.) When the filter screen 22 has trapped too many impurities and needs to be cleaned and replaced, rotate the adjusting wheel 34 in the reverse direction. The adjusting wheel 34 drives the worm gear 31 and worm 33 to reverse, and the internal thread ring 29 drives the screw 27 to reverse, thereby pulling the pressure block 24 upward. The pressure block 24 disengages from the opening of the circular block 21, and the upper end of the mounting groove is fully open. At this time, The filter screen 22 and sealing ring 23 can be directly removed from the mounting slot. Impurities can be cleaned or replaced with new filter screen 22 and sealing ring 23. The filter screen 22 blocks large particles of impurities in the slurry on the left side. Over time, these impurities will fall into the drain pipe 5. Then, unscrew the cover 6. After unscrewing, the dirt will drain from the drain pipe 5. After the dirt drains, screw the cover 6 back on. (A rubber sealing gasket can be placed on the inner wall of the cover 6 to ensure a tight seal between the drain pipe 5 and the cover 6.) After cleaning and replacement, rotating the adjusting wheel 34 clockwise will re-secure the filter screen 22 and restore filtration.

[0017] The working principle of the anti-clogging mining valve provided by this utility model is as follows: When using the anti-clogging mining valve, the valve body 1 and its upper part are connected in series in the mining fluid pipeline. First, the sealing ring 23 is placed on the outer surface of the filter screen 22. Then, the whole assembly of the sealing ring 23 and the filter screen 22 is inserted into the installation groove. After the filter screen 22 is inserted, the central axis of the filter screen 22 coincides with the central axis of the left side of the valve body 1. The elasticity of the sealing ring 23 can fill the gap, ensuring that the slurry cannot bypass the valve from the gap between the filter screen 22 and the installation groove. The valve body is constructed to ensure that all slurry is filtered through the filter screen 22, preventing unfiltered impurities from bypassing the filter screen 22 and clogging the valve body. Next, the adjusting wheel 34 is rotated, causing the worm 33 to rotate. The worm 33 meshes with the worm wheel 31, which in turn causes the internal threaded ring 29 to rotate around the cylinder 28. The internal threaded ring 29 is threadedly connected to the screw 27, and the lower end of the screw 27 is fixed to the pressure block 24. The pressure block 24 is guided by the guide rod 26 and the sliding hole of the bracket 25, restricting its movement to a vertical direction to prevent deviation. The pressure block 24 is inserted into the opening at the upper end of the circular block 21, pressing the filter screen 22 tightly into the mounting groove. Simultaneously, the rubber sealing ring 23 is squeezed to achieve a seal, ensuring the filter screen remains secure and leak-free during filtration. When the filter screen 22 traps too many impurities and needs cleaning and replacement, the adjusting wheel 34 is rotated in the reverse direction. The adjusting wheel 34 drives the worm gear 31 and worm 33 to reverse, and the internal threaded ring 29 drives the screw 27 to reverse, thereby pulling the pressure block 24 upwards. The pressure block 24 disengages from the opening of the circular block 21, completely opening the upper end of the mounting groove. At this point, the filter screen can be directly installed. Remove filter screen 22 and sealing ring 23 from the mounting slot, clean impurities or replace filter screen 22 and sealing ring 23. Filter screen 22 blocks large particles of impurities in the slurry on the left side of the slurry. If impurities are blocked for a long time, they will fall into the inside or surrounding area of ​​the drain pipe 5. Close the main flow of the valve body 1, then unscrew the cover 6. After the cover is unscrewed, the dirt will be discharged from the drain pipe 5. After the dirt is discharged, screw the cover 6 back on. After cleaning and replacement, rotate the adjusting wheel 34 in the forward direction to re-fix filter screen 22 and restore filtration.
