Description

Technical Field

[0001] The invention relates to the technical field of discharge valves, and in particular to a plug-in type ultra-high temperature corrosion-resistant discharge valve. Background Art

[0002] Ultra-high temperature corrosion-resistant discharge valve is a specially designed valve, mainly used in extremely high temperature and corrosive environments. It has been widely used in industrial fields such as petroleum, chemical, metallurgy, and electric power, especially in pipeline systems that handle high temperature, high pressure and corrosive media.

[0003] The working principle of the traditional plug-in type ultra-high temperature and corrosion-resistant discharge valve is to realize the opening and closing functions by the plug-in plate (valve disc) moving linearly along the center line of the fluid. However, although this special structure has good sealing performance, due to the structural characteristics of the valve, it will produce greater resistance when the fluid passes through, resulting in a large fluid pressure loss, affecting the efficiency of the system. In addition, since there is a gap between the sealing surface of the valve and the valve core, if the medium contains particles, high viscosity or easily coked substances, such as when installed at the discharge port of a glass reaction furnace, it is easy to cause the valve to be blocked or poorly sealed, affecting its normal use.

[0052] The working principle and beneficial effects of the present invention are:

[0053] 1. During installation, the present invention installs the liquid inlet pipe at one end of the furnace or the conveying pipeline, and connects the liquid discharge pipe to another pipeline of the high-temperature medium, so that the medium can flow through the liquid inlet pipe, the liquid hole and the liquid discharge pipe. During the flow process, not only will no excessive resistance be applied to the medium, but the transmission efficiency of the fluid will be ensured. When the fluid is cut off, firstly, the power tube is slid on the blocking tube through the power turntable, so that the hexagonal power groove on one side of the power tube is sleeved on the hexagonal blocking block. At this time, the main adjustment gear is separated from the adjustment gear, and then the power turntable is rotated. The rotation of the power turntable drives the power tube to rotate, and the rotation of the power tube drives the hexagonal The blocking block rotates, and the rotation of the hexagonal blocking block drives the blocking tube to rotate, and the rotation of the blocking block drives the blocking ball nut group to rotate. When the blocking ball nut group moves, the blocking screw moves downward, and the movement of the blocking screw drives the hollow blocking plate to move. When the hollow blocking plate moves, the hexagonal adjustment rod slides in the adjustment tube. When the hollow blocking plate moves to one side of the liquid hole, the fluid in the pipeline will flow through the pressure relief hole and the second-stage hole. In the process of blocking the medium fluid through the hollow blocking plate, the aperture of the medium is continuously reduced. In order to prevent the water hammer effect caused by cutting off the fluid too quickly, part of the medium will be discharged through the pressure relief hole at this time.

[0054] 2. According to the present invention, when the fluid is cut off for the second time, the power turntable is used to slide the power tube on the blocking tube to separate the power tube from the hexagonal blocking block, and at the same time, the adjustment main gear is meshed with the adjustment slave gear. At this time, the power disk is continued to be rotated, and the rotation of the power disk drives the power tube to rotate, and the rotation of the power tube drives the adjustment main gear to rotate, and the rotation of the adjustment main gear drives the adjustment slave gear to rotate, and the rotation of the adjustment slave gear drives the adjustment tube to rotate, and the rotation of the adjustment tube drives the hexagonal adjustment rod to rotate, and the rotation of the hexagonal adjustment rod drives the two-stage ball nut group to rotate, and the rotation of the two-stage ball nut group causes the two-stage screw rod to move upward, and the movement of the two-stage screw rod drives the two-stage gate plate to move, and the two-stage hole and the pressure relief hole are misaligned through the movement of the two-stage gate plate, so as to realize complete interception of the fluid. In the interception process, even if the fluid contains particulate matter, the particulate matter will accumulate on the hole wall of the two-stage hole. When the two-stage hole and the pressure relief hole overlap again, the particulate matter will continue to flow with the fluid, and will not affect the sealing performance of the stop valve.

[0055] 3. In the present invention, when the liquid hole is blocked and the flow is intercepted by the movement of the hollow sealing plate, the hollow sealing plate will preferentially contact the anti-slag slider as it moves, and after contacting the anti-slag slider, it will continue to drive the anti-slag slider to move in the direction of the anti-blocking cleaning plate and compress the anti-slag spring, even if there are impurity particles between the hollow anti-blocking plate and the anti-slag slider, when the anti-slag slider completely crosses the liquid hole, the liquid hole will be completely sealed. After the hollow anti-blocking plate moves upward and leaves the liquid hole, the anti-slag slider will continue to move to its original position under the rebound of the anti-slag spring, and the impurities adhered to the edge of the anti-slag slider can be washed away by continuing to transport the fluid. In actual use, when the particulate matter in the fluid is squeezed by the hollow anti-blocking plate and adheres to the anti-slag slider, the anti-slag slider can be taken out of the hollow gate plate for cleaning by disassembling the anti-blocking cleaning plate.

[0073] As mentioned above, the hollow gate plate 2 passes through and is sealed in the valve body 1. The hollow gate plate 2 divides the valve body 1 into a liquid inlet area and a liquid discharge area. Two liquid holes are opened on the hollow gate plate 2, and the two liquid holes are respectively connected with the liquid inlet area and the liquid discharge area.

[0074] Specifically, when the particles in the fluid are squeezed by the hollow anti-blocking plate and adhere to the anti-slag slider 4, the anti-blocking cleaning plate 3 can be disassembled to remove the anti-slag slider 4 from the hollow gate plate 2 for cleaning.

[0075] As mentioned above, the two-stage plugging mechanism 002 is sealed and detachably arranged on the valve body 1, and the two-stage plugging mechanism 002 is sealed and slidably arranged in the valve body 1 to cut off the fluid medium.

The plugging cover 7 is sealed and detachably arranged on the valve body 1, and the plugging adjustment component is arranged on the plugging cover 7. And the blocking adjustment component is connected to the hollow blocking plate 6, and is used to adjust the position of the hollow blocking plate 6. The two-stage gate plate 8 is sealingly and slidably arranged in the hollow blocking plate 6. The two-stage gate plate 8 is provided with two-stage holes connected to the pressure relief hole. There are two two-stage adjustment components, which are arranged between the blocking cover 7 and the hollow blocking plate 6, and the two-stage adjustment component passes through the hollow blocking plate 6 and is connected to the two-stage gate plate 8. Two two-stage adjustment components are arranged on both sides of the blocking adjustment component for adjusting the position of the two-stage gate plate 8. The positioning power component is slidably arranged on the blocking adjustment component, and the positioning power component is engaged with the two-stage adjustment component.

[0076] Among them, the blocking adjustment component includes a blocking ball nut group 9, a blocking screw 10, a blocking tube 11 and a hexagonal blocking block 12. The blocking ball nut group 9 is rotatably set on the blocking cover 7. The blocking screw 10 is threadedly connected in the blocking ball nut group 9. One end of the blocking screw 10 is connected to the hollow blocking plate 6. One end of the blocking tube 11 is set at the end of the blocking ball nut group 9 away from the hollow blocking plate 6. The blocking screw 10 is located in the blocking tube 11. The other end of the blocking tube 11 passes through the top of the blocking cover 7. The hexagonal blocking block 12 is set on the side of the blocking tube 11 away from the hollow blocking plate 6.

[0078] Among them, the positioning power assembly includes a power turntable 19, a power tube 20 and a positioning main gear 21. The power tube 20 is arranged at the center position of the power turntable 19. The power tube 20 is sleeved on the blocking tube 11. One end of the power tube 20 is provided with a hexagonal power groove adapted to the hexagonal blocking block 12. The positioning main gear 21 is arranged on the power tube 20, and the positioning main gear 21 is meshed with the positioning slave gear 18.

[0079] Specifically, firstly, the power turntable 19 is used to slide the power tube 20 on the blocking tube 11, so that the hexagonal power groove on one side of the power tube 20 is sleeved on the hexagonal blocking block 12. At this time, the main adjustment gear 21 is separated from the adjustment slave gear 18, and then the power turntable 19 is rotated. The rotation of the power turntable 19 drives the power tube 20 to rotate, and the rotation of the power tube 20 drives the hexagonal blocking block 12 to rotate. The rotation of the hexagonal blocking block 12 drives the blocking tube 11 to rotate, and the rotation of the blocking block drives the blocking ball nut group 9 to rotate.

At this time, the power disk is continued to be rotated, and the rotation of the power disk drives the power tube 20 to rotate, and the rotation of the power tube 20 drives the adjustment main gear 21 to rotate, and the rotation of the adjustment main gear 21 drives the adjustment slave gear 18 to rotate, and the rotation of the adjustment slave gear 18 drives the adjustment tube 16 to rotate, and the rotation of the adjustment tube 16 drives the hexagonal adjustment rod 17 rotates, and the rotation of the hexagonal adjusting rod 17 drives the second-stage ball nut group 14 to rotate. The rotation of the second-stage ball nut group 14 makes the second-stage screw 15 move upward. The movement of the second-stage screw 15 drives the second-stage gate 8 to move. The movement of the second-stage gate 8 makes the second-stage hole and the pressure relief hole misaligned to achieve complete interception of the fluid. During the interception process, even if the fluid contains particulate matter, the particulate matter will accumulate on the hole wall of the second-stage hole. When the second-stage hole and the pressure relief hole overlap again, the particulate matter will continue to flow with the fluid and will not affect the sealing of the stop valve.

[0081] It should be noted that a power cover 22 is also provided on the blocking cover 7. The main adjustment gear 21 and the slave adjustment gear 18 are both located inside the power cover 22. The power pipe 20 passes through the power cover 22 to protect the main adjustment gear 21 and the slave adjustment gear 18 and extend their service life.
