Description

Technical Field

[0001] This utility model relates to the field of industrial technology, and more specifically, to an anti-corrosion valve. Background Technology

[0002] In industries such as chemical, petroleum, and water treatment, valves are critical control devices used to regulate and control the flow of various fluids. However, these fluids are often corrosive, such as acids, alkalis, and salt solutions. Under the influence of these corrosive media, traditional metal valves are prone to rusting and corrosion during long-term use. For example, acidic solutions in chemical plants and brine in oil pipelines can have a strong corrosive effect on metal valves, leading to a decline in valve performance or even failure to function properly. In such cases, not only will production efficiency be affected, but safety hazards may also arise. Utility Model Content

On the outer wall of the valve stem, the pressure ring is installed on the outside of the locking sleeve. An oil injection mechanism is provided on the mounting base. Multiple sets of the oil injection mechanism are installed on the mounting base. The oil injection mechanism includes a sealing sleeve, a flow pipe, an oil leakage hole, a sealing rod, a push spring, an extension rod, and a stop block. The sealing sleeve is installed on the mounting base. The flow pipe is installed inside the sealing sleeve. Multiple sets of oil leakage holes are distributed on the flow pipe. The sealing rod slides inside the flow pipe. The two ends of the push spring are respectively connected to the sealing rod and the sealing sleeve. The extension rod is installed on the outer end of the sealing rod. The stop block is installed on the top end of the extension rod.

[0007] The present invention is further configured such that a push sleeve is installed on the bottom surface of the handwheel, and the bottom surface of the push sleeve is provided with an angle. This design enables the downward movement of the handwheel to automatically trigger the opening of the oiling mechanism.

[0008] The present invention is further configured such that each of the multiple sets of card blocks is equipped with an unlocking spring at its top, and the two ends of the multiple sets of unlocking springs are respectively connected to the card block and the outer wall of the fixing sleeve. This design ensures that the card block can be quickly and reliably disengaged from the card slot.

[0009] The present invention is further provided that a compression spring is provided between the locking sleeve and the fixing sleeve, and multiple sets of compression springs are provided. The design of multiple sets of compression springs provides sufficient elastic restoring force to ensure that the locking sleeve can be quickly and stably reset.

[0010] The present invention is further configured such that the inner wall of the flow tube is provided with a guide strip and the outer wall of the sealing rod is provided with a guide groove. Multiple sets of the guide strip and the guide groove are provided and slidably connected. The cooperation between the guide strip and the guide groove ensures the smooth sliding of the sealing rod and improves the reliability and stability of the oil injection mechanism.

[0011] The present invention is further provided that a sealing gasket is installed on the inner wall of the mounting base, and the inner wall of the sealing gasket is in contact with the outer wall of the locking rod.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a corrosion-resistant valve, which has the following beneficial effects:

[0016] 1. The fixing mechanism, through the cooperation of the fixing sleeve, the locking block, the locking sleeve, the locking groove, and the pressure ring, achieves reliable fixing and quick unlocking of the handwheel and the valve stem. When it is necessary to operate the valve, pressing the pressure spring moves the locking sleeve downward, releasing the contact with the locking block. Under the action of the unlocking spring, the locking block moves outward, thereby disengaging from the locking groove and releasing the fixed connection between the handwheel and the valve stem. This design not only improves the convenience of operation but also ensures the stability of the handwheel in the non-operational state, avoiding misoperation and safety hazards caused by a loose handwheel.

[0017] 2. The oil injection mechanism achieves automatic injection and uniform distribution of lubricating oil through the coordinated action of the sealing sleeve, flow pipe, oil leakage hole, sealing rod, push spring, extension rod, and stop block. When the handwheel moves downward, the inclined surface of the push sleeve abuts against the stop block, pushing the sealing rod to slide along the flow pipe. The sealing state of the sealing rod is released, and the lubricating oil is evenly distributed to the contact surface of the valve stem and valve core through the oil leakage hole, effectively preventing rust and corrosion of the valve stem and valve core. This design not only extends the service life of the valve but also reduces the maintenance frequency and improves the reliability and working efficiency of the valve.

[0018] 3. The oil replenishment assembly, through the design of an annular pipe, an oil replenishment pipe, and a sealing cap, enables convenient replenishment of lubricating oil. When lubricating oil needs to be replenished, the sealing cap is unscrewed, and lubricating oil is injected into the annular pipe through the oil replenishment pipe. The lubricating oil is evenly distributed into multiple sets of sealing sleeves through the annular pipe. Then, the sealing cap is tightened to ensure the sealing of the oil replenishment pipe and prevent lubricating oil leakage. This design not only simplifies the oil replenishment operation but also ensures the uniform distribution of lubricating oil, improving the valve's corrosion resistance and reliability.

[0028] Please see Figures 1-5 A corrosion-resistant valve includes a valve body 1, a mounting base 2 mounted on the valve body 1, a valve stem 3 housed within the mounting base 2, a valve core 4 threadedly connected to the bottom end of the valve stem 3, a handwheel 5 slidably mounted on the top end of the valve stem 3, and a fixing mechanism provided on the handwheel 5. The fixing mechanism includes a fixing sleeve 6, a locking block 7, a locking sleeve 8, a locking groove 9, and a pressure ring 10. The fixing sleeve 6 is mounted on the handwheel 5, the locking block 7 is slidably mounted on the fixing sleeve 6 in multiple sets, the locking sleeve 8 is slidably mounted on the outer wall of the fixing sleeve 6, the locking groove 9 is distributed in multiple sets on the outer wall of the valve stem 3, and the pressure ring 10 is mounted on the outer side of the locking sleeve 8. The mounting base 2 is equipped with an oil injection mechanism. Multiple sets of the oil injection mechanism are installed on the mounting base 2. The oil injection mechanism includes a sealing sleeve 11, a flow pipe 12, an oil leakage hole 13, a sealing rod 14, a push spring 15, an extension rod 16, and a stop block 17. The sealing sleeve 11 is installed on the mounting base 2, the flow pipe 12 is installed inside the sealing sleeve 11, multiple sets of oil leakage holes 13 are distributed on the flow pipe 12, the sealing rod 14 slides inside the flow pipe 12, the two ends of the push spring 15 are respectively connected to the sealing rod 14 and the sealing sleeve 11, the extension rod 16 is installed on the outer end of the sealing rod 14, and the stop block 17 is installed on the top end of the extension rod 16.

[0029] A push sleeve 18 is installed on the bottom surface of the handwheel 5. The bottom surface of the push sleeve 18 is provided with an angle. Through the action of the angle, the downward force is converted into a lateral thrust.

[0030] Each of the multiple sets of locking blocks 7 is equipped with an unlocking spring 19 at its top. The two ends of the multiple sets of unlocking springs 19 are respectively connected to the locking block 7 and the outer wall of the fixing sleeve 6. The elastic restoring force of the unlocking spring 19 pushes the locking block 7 outward, causing the locking block 7 to disengage from the slot 9.

[0031] A compression spring 20 is provided between the locking sleeve 8 and the fixing sleeve 6. Multiple sets of compression springs 20 are provided. When the locking sleeve 8 is released, the elastic restoring force of the compression spring 20 pushes the locking sleeve 8 to move upward.

[0032] The inner wall of the flow tube 12 is provided with a guide strip 21, and the outer wall of the sealing rod 14 is provided with a guide groove 22. Multiple sets of guide strips 21 and guide grooves 22 are provided and slidably connected to ensure the linear movement of the sealing rod 14 in the flow tube 12 and prevent the sealing rod 14 from deviating or getting stuck during the sliding process.

[0033] A sealing gasket 23 is installed on the inner wall of the mounting base 2. The inner wall of the sealing gasket 23 is in contact with the outer wall of the locking rod. The function of the sealing gasket 23 is to form a seal between the locking rod and the mounting base 2 to prevent lubricating oil leakage.

[0034] A sealing ring 24 is installed on the inner wall of the flow pipe 12. The function of the sealing ring 24 is to further enhance the sealing performance of the flow pipe 12 when the sealing rod 14 is in a sealed state.

[0035] In this embodiment, during use, pressing down on the compression spring 20 causes the locking sleeve 8 to move downwards and compresses the compression spring 20. The downward movement of the locking sleeve 8 releases the contact with the multiple sets of locking blocks 7. The multiple sets of locking blocks 7 are pulled outwards by the elastic reset of the unlocking spring 19, thereby causing the multiple sets of locking blocks 7 to move out of the slot 9 and release the fixed connection between the valve stem 3 and the handwheel 5. Then, the handwheel 5 is slid down to drive the push sleeve 18 to move. The inclined surface at the bottom of the push sleeve 18 abuts against the multiple sets of abutting blocks 17 and pushes the multiple sets of abutting blocks 17 to move. The abutment block 17 pushes the extension rod 16 and the sealing rod 14 to slide along the flow pipe 12, releasing the sealing state of the sealing rod 14. The lubricating oil is evenly distributed to the contact surface of the valve stem 3 and the valve core 4 through the oil leakage hole 13 to prevent them from rusting. This completes the use process of the anti-rust and anti-corrosion valve. After the oil is filled, the handwheel 5 is slid upward, so that the fixing sleeve 6 moves to the outside of the slot 9. The elastic reset of the compression spring 20 pushes the locking sleeve 8 to slide upward. The locking sleeve 8 abuts against the top of the multiple sets of locking blocks 7 and compresses the multiple sets of unlocking springs 19. The locking sleeve 8 inside the locking block 7 pushes so that its bottom end is locked in the slot 9, completing the fixing of the handwheel 5.

[0036] Please see Figure 3 As one implementation of the oil replenishment component: an oil replenishment component is provided on the outside of the mounting base 2. The oil replenishment component includes an annular tube 25, an oil replenishment pipe 26 and a sealing cap 27. The annular tube 25 is provided on the outside of the mounting base 2 and is connected to multiple sets of sealing sleeves 11. The oil replenishment pipe 26 is installed on the annular tube 25, and the sealing cap 27 is threaded to the top of the oil replenishment pipe 26.

[0037] More specifically, when lubricating oil needs to be replenished, first unscrew the sealing cap 27, inject lubricating oil into the annular pipe 25 through the oil replenishment pipe 26, and the lubricating oil is evenly distributed into multiple sets of sealing sleeves 11 through the annular pipe 25. Then tighten the sealing cap 27 to ensure the sealing state of the oil replenishment pipe 26 and prevent lubricating oil leakage.

[0038] In summary, during the use or operation of the overall equipment: When in use, pressing down on the compression spring 20 causes the locking sleeve 8 to move downwards, compressing the compression spring 20. The downward movement of the locking sleeve 8 releases the contact with the multiple sets of locking blocks 7. The multiple sets of locking blocks 7 are pulled outwards by the elastic reset of the unlocking spring 19, thereby causing the multiple sets of locking blocks 7 to move out of the slot 9 and release the fixed connection between the valve stem 3 and the handwheel 5. Then, sliding the handwheel 5 downwards causes the push sleeve 18 to move. The inclined surface at the bottom of the push sleeve 18 contacts the multiple sets of abutment blocks 17 and pushes the multiple sets of abutment blocks 17 to move. The abutment block 17 pushes the extension rod 16 and the sealing rod 14 to slide along the flow pipe 12, releasing the sealing state of the sealing rod 14. The lubricating oil is evenly distributed to the contact surface of the valve stem 3 and the valve core 4 through the oil leakage hole 13 to prevent them from rusting. This completes the use process of the anti-rust and anti-corrosion valve. After the oil is filled, the handwheel 5 is slid upward, so that the fixing sleeve 6 moves to the outside of the slot 9. The elastic reset of the compression spring 20 pushes the locking sleeve 8 to slide upward. The locking sleeve 8 abuts against the top of the multiple sets of locking blocks 7 and compresses the multiple sets of unlocking springs 19. The locking sleeve 8 inside the locking block 7 pushes so that its bottom end is locked in the slot 9, completing the fixing of the handwheel 5.

[0039] When lubricating oil needs to be replenished, first unscrew the sealing cap 27 and inject lubricating oil into the annular pipe 25 through the oil replenishment pipe 26. The lubricating oil is evenly distributed into multiple sets of sealing sleeves 11 through the annular pipe 25. Then tighten the sealing cap 27 to ensure the sealing state of the oil replenishment pipe 26 and prevent lubricating oil leakage.

For all the fixed connections mentioned above, welding is preferred.
