The cryogenic valve can filter and divide and pressure-divide the liquid, thereby making it less likely for the subsequent cryogenic valve to have a poor low-temperature seal caused by warping and deformation of the sealing surface, and thus less likely to have internal leakage problems.

Description

Technical Field

[0001] The present invention relates to the technical field of cryogenic valves, in particular to a cryogenic valve with a pressure regulating function. Background Art

[0002] Cryogenic valves include cryogenic ball valves, cryogenic gate valves, cryogenic stop valves, cryogenic safety valves, cryogenic check valves, cryogenic butterfly valves, cryogenic needle valves, cryogenic throttle valves, cryogenic pressure reducing valves, etc. They are mainly used in ethylene, liquefied natural gas devices, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tanks and tank trucks, pressure swing adsorption oxygen production devices, etc. The output liquid cryogenic media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc. are not only flammable and explosive, but also need to be gasified when heated. When gasified, the volume expands hundreds of times. The application of cryogenic valves controls the temperature and prevents hidden dangers such as explosion and leakage.

[0003] At present, when the cryogenic valves on the market are used, they need to be connected to the pipeline for use. At the same time, the cryogenic valve can effectively control the temperature of the medium. In actual use, after the cryogenic valve is connected to the pipeline, the cryogenic valve is mostly used to control the flow direction of compressed gas and liquid. The compressed gas and liquid have a relatively high pressure themselves, and when the compressed gas and liquid flow to the cryogenic valve in the pipeline, it is easy for the compressed gas and liquid to impact the cryogenic valve, causing the internal pressure of the cryogenic valve to increase instantly, which makes the subsequent cryogenic valve prone to warping and deformation of the sealing surface that was originally ground with high precision, resulting in poor cryogenic sealing, and then internal leakage problems.

When the compressed gas and liquid flow to the cryogenic valve in the pipeline, it is easy for the compressed gas and liquid to impact the cryogenic valve, causing the instantaneous internal pressure of the cryogenic valve to increase.

When the rotating rod is rotated, the flanges on both sides of the valve body are connected to the pipeline ports, the gasket is not easily moved out from the gasket groove, thereby making it more convenient to connect the flanges at both ends of the subsequent valve body to the outside of the pipeline.

[0038] The working principle of the present invention is as follows: the flanges 4b04 at both ends of the valve body 1 are connected with the pipeline, the liquid enters the connecting groove 5 from the pipeline, and is pressure-divided through the holes outside the pressure-dividing plate 4a10, so that the liquid is filtered and pressure-divided through the pressure-dividing plate 4a10 inside the connecting groove 5 and enters the valve groove 2. At this time, the valve stem 6 is rotated, so that the valve stem 6 drives the multiple pressure-dividing plates 8 to move through the extrusion plate 7, so that the pressure-dividing plates 8 slowly rise. At this time, the liquid can enter the multiple pressure-dividing grooves 10 outside the pressure-dividing plate 8 through the liquid inlet hole for pressure-dividing and shunting, so that the liquid is pressure-divided and shunted into the other side of the valve groove 2. When the pressure-dividing plate 4a10 is used for a long time and is clogged by impurities and impact-worn, the rotating rod 401 is pulled at this time, and the rotating rod 401 is at the first The first adjusting groove 4a02 slides inside, and the rotating rod 401 drives the positioning plate 402 to move at the same time, so that the positioning plate 402 enters the first adjusting groove 4a02, and the rotating rod 401 is rotated. The rotating rod 401 drives the first adjusting disk 4a01 to move through the positioning plate 402 and the first adjusting groove 4a02, so that the first adjusting disk 4a01 rotates slightly inside the groove 3, and the first adjusting disk 4a01 drives the first rotating plate 4a03 to make a small circular motion inside the groove 3. At the same time, the first adjusting disk 4a01 drives the second rotating plate 4a04 to make a small circular motion inside the groove 3, and the first rotating plate 4a03 and the second rotating plate 4a04 respectively drive the first magnet 4a05 and the second magnet 4a06 to rotate in the groove 3. The groove 3 has a small circular motion inside, and the second rotating plate 4a04 drives the telescopic spring 4a12 to move at the same time, so that the telescopic spring 4a12 is stretched, so that the subsequent first rotating plate 4a03 drives the first magnet 4a05 away from the third magnet 4a09, and the second rotating plate 4a04 drives the second magnet 4a06 to reach the top of the third magnet 4a09, and the second magnet 4a06 and the third magnet 4a09 attract each other, and the third magnet 4a09 drives the positioning rod 4a08 to slide inside the groove 3, and the positioning rod 4a08 moves with the fixing plate 4a07 at the same time, and the bottom end of the positioning rod 4a08 will separate from the positioning groove 4a11, and at this time, the pressure dividing plate 4a10 is pulled to make the pressure dividing plate 4a10 move from the connecting plate 4a10 to the connecting plate 4a11. 8.

At this time, the rotating rod 401 is released, and the elastic force of the telescopic spring 4a12 drives the second rotating plate 4a04 to reset, so that the subsequent second magnet 4a06 is away from the first magnet 4a05, and the first magnet 4a05 reaches the top of the third magnet 4a09. The first magnet 4a05 and the third magnet 4a09 repel each other, so that the third magnet 4a09 drives one end of the positioning rod 4a08 to enter the positioning slot 4a11, so that the position of the subsequent pressure dividing plate 4a10 is restricted, and the subsequent liquid filtration pressure division is not affected.

When the roller 4b10 moves, the roller 4b10 can drive the movable plate 4b07 to move, so that the movable plate 4b07 moves on the outer wall of the stabilizing rod 4b08.

[0041] In a preferred embodiment, a valve stem 6 is provided inside the valve groove 2, and an extrusion disk 7 is fixedly connected to the bottom end of the valve stem 6, and a pressure dividing plate 8 is fixedly connected to the bottom end of the extrusion disk 7. When the first adjusting disk 4a01 moves, the first adjusting disk 4a01 can drive the first rotating plate 4a03 to move, so that the first rotating plate 4a03 moves inside the groove 3.

[0043] The working principle of the present invention is as follows: when the flanges 4b04 at both ends of the valve body 1 are connected to the outside of the pipeline, the bottom end of the rotating rod 401 enters the second adjusting groove 4b02, the rotating rod 401 drives the positioning plate 402 to enter the second adjusting groove 4b02, and the rotating rod 401 is rotated. The rotating rod 401 drives the second adjusting disk 4b01 to rotate through the positioning plate 402 and the second adjusting groove 4b02, and the second adjusting disk 4b01 drives the extrusion block 4b03 to move, and the extrusion block 4b03 makes a small circular motion inside the groove 3. The top of the extrusion block 4b03 is in an arc shape, so that when the top of the extrusion block 4b03 contacts the roller 4b10, the second adjusting disk 4b01 drives the roller 4b10 to move through the extrusion block 4b03, so that the roller 4b10 slides upward, and the roller 4b10 drives the moving plate 4b07 to move, so that the moving plate 4b07 slides inside the groove 3, and the moving plate 4b07 is simultaneously on the stabilizing rod When the outer wall of 4b08 slides, the movable plate 4b07 squeezes the reset spring 4b09, causing the end of the movable plate 4b07 away from the roller 4b10 to enter the fixed groove 4b06 from the gasket groove 4b05. At this time, the sealing gasket enters the gasket groove 4b05, and the rotating rod 401 is released. At this time, the roller 4b10 loses the squeeze of the squeeze block 4b03, and the reset spring 4b09 resets the movable plate 4b07, so that the movable plate 4b07 b07 slides and resets on the outer wall of the stabilizing rod 4b08, so that one end of the movable plate 4b07 moves away from the roller 4b10 and enters the gasket groove 4b05 from the inside of the fixed groove 4b06, so that one end of the movable plate 4b07 squeezes and limits the gasket. At this time, when the flanges 4b04 on both sides of the valve body 1 are connected to the pipeline port, the gasket is not easy to move out from the gasket groove 4b05, thereby making it easier to connect the flanges 4b04 at both ends of the subsequent valve body 1 with the outside of the pipeline.
