Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically to an ultra-high pressure valve device with safety indication. Background Technology

[0002] Valves are devices used in fluid systems to control the direction, pressure, and flow rate of fluids. They enable the flow or stop of media (liquids, gases, powders) in piping and equipment and can control their flow rate. They are widely used in the oil extraction industry.

[0003] In the prior art, patent number CN114001196A, entitled "A Fully Enclosed High-Temperature and High-Pressure Oil Production Valve," includes a main valve body. A fixed valve seat is fixedly installed on the upper surface of the main valve body, and a valve connecting pipe is fixedly installed on the upper surface of the fixed valve seat. An inlet pipe is fixedly installed on one side of the main valve body, and a secondary square chamber is fixedly installed on the other side of the main valve body. An outlet pipe is fixedly installed on one side of the secondary square chamber. The secondary square chamber contains a pressure chamber and a sealing chamber. This invention can monitor the closing status of the main valve body. When the main valve body is not tightly closed and a slight leakage occurs, the sealing pad moves upward, and the change is displayed through the indicator line interlayer and the indicator scale, thereby facilitating the detection of minor leakage in the main valve body and improving valve sensitivity and operational reliability.

[0004] However, in existing high-pressure oil delivery pipelines, minor leaks and spills often occur even after the valves are closed. These minor leaks not only cause losses but are also extremely dangerous, posing safety hazards. Currently, there is a lack of a system that can monitor the closure status of the main valve after it is closed. Summary of the Invention

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 10 The present invention provides a technical solution:

[0032] Example 1: An ultra-high pressure valve device with safety indication includes: a valve body 1, a pipe 2 at one end of the valve body 1, an extension rod 3 at the bottom of the pipe 2, a first lifting groove 14 inside the extension rod 3, a lifting block 13 inside the first lifting groove 14, a first lifting rod 7 at the end of the lifting block 13, a through groove 19 on the surface of the first lifting rod 7, a screw hole 23 and a float block 21 inside the through groove 19, a screw rod 22 at the bottom of the float block 21, and a second lifting rod 17 at the top of the float block 21. Liquid causes the float block 21 to float, and the float block 21 drives the second lifting rod 17 to move upward. The surface of the second lifting rod 17 is provided with a scale 18, which can be used to detect whether the valve body 1 has leaked.

[0033] Example 2: Based on Example 1, a fixing rod 6 is fixed to the top of the pipe 2. Multiple sets of fixing rods 6 are provided. A threaded ring 5 is fixed to the top of the fixing rod 6. A screw 4 is screwed into the inside of the threaded ring 5. A second screw head 35 is fixed to the top of the screw 4. The screw 4 rotates with the second screw head 35. A second sealing plate 10 and a first sealing plate 8 are fixed to the surface of the first lifting rod 7. The second sealing plate 10 is located outside the pipe 2, and the first sealing plate 8 is located inside the pipe 2. A rubber ring 9 is provided on the surface of the second sealing plate 10 near the pipe 2, and a rubber ring 9 is provided on the surface of the first sealing plate 8 near the second sealing plate 10. A transverse groove 33 is opened inside the threaded rod 22. An extension plate 32 is fixed to the surface of the telescopic block 24. The extension plate 32 is located in the telescopic block 24 and can move within the telescopic block 24. A magnet 31 is fixed to the surface of the extension plate 32. A magnet 31 is fixed in the middle of the transverse groove 33. An adsorption rod 30 is provided, the end of which can be adsorbed onto the surface of the magnet 31. A spring 34 is provided on the outside of the adsorption rod 30. One end of the spring 34 is connected to the inner wall of the transverse groove 33, and the other end of the spring 34 is connected to the surface of the extension plate 32. The spring 34 has tension, which makes the extension plate 32 close to the side of the rotating rod 16. The side of the telescopic block 24 away from the rotating rod 16 is provided with threads. When the telescopic block 24 extends out of the telescopic groove 25, the threaded side of the telescopic block 24 is located outside the screw rod 22. The threads on the surface of the telescopic block 24 enable the screw rod 22 to be screwed into the screw hole 23. The second sealing plate 10 and the first sealing plate 8 are supported on the surface and inner wall of the pipe 2 after the first lifting rod 7 moves. The surface of the pipe 2 has a hole, and the first lifting rod 7 is inserted into the hole. The rubber rings 9 on the surface of the second sealing plate 10 and the first sealing plate 8 are supported on both sides of the hole on the surface of the pipe 2.

[0034] An arc-shaped rod 12 is fixed inside the pipe 2, and a protective ring 11 is fixed at the end of the arc-shaped rod 12. The protective ring 11 is located outside the first lifting rod 7. The lifting block 13 is fixed at the bottom of the first lifting rod 7. The lifting block 13 moves up and down with the first lifting rod 7. The lifting block 13 is inserted into the inside of the first lifting groove 14. The lifting block 13 can move up and down in the first lifting groove 14. A limit plate is fixed at the top of the first lifting rod 7. A limit groove is opened at the bottom of the screw 4. The limit plate has a T-shaped cross section. The limit groove has a T-shaped cross section. The limit plate is inserted into the limit groove. The limit plate can rotate in the limit groove.

[0035] The surface of the second lifting rod 17 is provided with scales 18, and multiple sets of scales 18 are provided. A rotating rod 16 is inserted into the top of the second lifting rod 17, and a first screw head 15 is fixed to the top of the rotating rod 16. The rotating rod 16 rotates and moves with the first screw head 15. A second lifting groove 20 is opened inside the first lifting rod 7, and the second lifting rod 17 is located in the second lifting groove 20 and can rotate and move in the second lifting groove 20. A floating block 2 is fixed to the bottom of the second lifting rod 17. 1. The float block 21 has buoyancy. A threaded rod 22 is fixed to the bottom of the float block 21. The threaded rod 22 and the float block 21 move up and down with the second lifting rod 17. A threaded hole 23 is opened at the bottom of the first lifting rod 7. Multiple sets of top holding rings 28 are fixed to the surface of the rotating rod 16. The top holding rings 28 move with the rotating rod 16. A threaded block 29 is fixed to the bottom of the rotating rod 16. The surface of the threaded block 29 is provided with threads. The threaded rod 22 is provided with threaded holes. The threaded block 29 is screwed into the threaded rod 22. In the threaded hole of the screw rod 22, a telescopic groove 25 is provided inside, and a telescopic block 24 is provided in the telescopic groove 25. The telescopic block 24 can move in the telescopic groove 25. A force-bearing block 26 is fixed on the surface of the telescopic block 24. The force-bearing block 26 moves with the telescopic block 24. A support block 27 is fixed at the end of the force-bearing block 26. The force-bearing block 26 and the support block 27 are located in the threaded hole inside the screw rod 22, and the support ring 28 supports the surface of the force-bearing block 26 after moving, so that the force-bearing block 26 drives the telescopic block 24 to move. As the top holding ring 28 continues to descend, the top holding block 27 presses against the surface of the top holding ring 28. The rotating rod 16 drives the screw block 29 to rotate, and the screw block 29 moves down inside the screw rod 22, causing the top holding ring 28 to move down. The top holding ring 28 presses against the surface of the force-bearing block 26, causing the force-bearing block 26 to drive the telescopic block 24 to move. The telescopic block 24 extends out of the telescopic groove 25. When the second lifting rod 17 is screwed, the screw rod 22 is screwed into the screw hole 23, stabilizing the second lifting rod 17 so that it will not float up and down.

[0036] Liquid flows into the valve body 1 through pipe 2, where it is blocked and circulated by the valve body inside. When valve body 1 is opened, the liquid flows inside pipe 2. Tightening the second screw head 35 causes the screw 4 to rotate and move downward inside the threaded ring 5. The screw 4 drives the first lifting rod 7 to move upward. As the first lifting rod 7 moves upward, the second sealing plate 10 on the surface moves upward, and the first sealing plate 8 presses against the surface of the pipe 2, thus sealing the pipe. This allows the lifting block 13 to be positioned at the top of the first lifting groove 14, preventing liquid from flowing into the first lifting groove 14. The protective ring 11 covers the outside of the through groove 19, preventing liquid from impacting the inside of the through groove 19. Twisting the first screw head 15 drives the rotating rod 16 to rotate, which in turn drives the screw block 29 to rotate. The screw block 29 moves downward inside the screw rod 22, causing the top holding ring 28 to move downward. The top holding ring 28 presses against the surface of the force-bearing block 26, causing the force-bearing block 26 to move the telescopic block 24. The telescopic block 24 extends out of the telescopic groove 25. When the second lifting rod 17 is screwed, the screw rod 22 is screwed into the screw hole 23, stabilizing the second lifting rod 17 and preventing it from floating up and down. When the valve body 1 is closed, twisting the second screw head 35 causes the second screw head 35 to move the first lifting rod 7 downward, thus sealing the pipe. As the first lifting rod 7 moves downward, the second sealing plate 10 presses against the surface of the pipe 2, providing a sealing effect. The lifting block 13 moves downward into the first lifting groove 14 along with the first lifting rod 7. When the valve body 1 leaks, the liquid enters the first lifting groove 14 and then enters the second lifting groove 20 through the through groove 19. The liquid causes the float block 21 to float, and the float block 21 drives the second lifting rod 17 to move upward. The surface of the second lifting rod 17 is provided with a scale 18, which can be used to detect whether the valve body 1 has leaked. After the rotating rod 16 moves upward, the top holding ring 28 no longer presses against the surface of the force block 26, allowing the telescopic block 24 to enter the telescopic groove 25 under the pull of the spring 34. The adsorption rod 30 is adsorbed onto the surface of the magnet 31, making the telescopic block 24 stable in the telescopic groove 25. The screw rod 22 is no longer screwed into the screw hole 23, and the second lifting rod 17 can move freely. The float block 21 is not affected when it floats.
