Description

Technical Field

[0001] The invention relates to the technical field of pressure reducing valves, and in particular to a novel pressure reducing valve. Background Art

[0002] The pressure reducing valve is an important fluid control device, which is widely used in various occasions where the fluid or gas pressure needs to be adjusted and controlled. It reduces the inlet pressure to a certain required outlet pressure and relies on the energy of the medium itself to automatically keep the outlet pressure stable.

[0003] Although the technology of pressure reducing valves has made significant progress, there are still some problems in practical applications. For example, traditional pressure reducing valves generally only use a single pressure reducing module for pressure reduction, and the pressure reducing valve is generally connected to the two ends of the pipeline and the fixed frame by several bolts. When the pressure reducing valve needs to be maintained or replaced, it takes a long time to maintain and disassemble, which affects the fluid transportation. In addition, when used in some high-pressure situations, when the fluid pressure suddenly drops too much through the pressure reducing valve, cavitation and large fluid dynamic noise are prone to occur, which can easily damage the valve body and pipeline and affect the service life.

[0004] In view of the above problems, the present invention document proposes a new type of pressure reducing valve. Summary of the invention

[0029] In this embodiment: the propulsion component 102 drives the connection component 104 and the docking component 103 to separate from the switchable pressure reducing valve component 201, and then the adjustment component 203 adjusts the position of the switchable pressure reducing valve component 201, so that the position of the pressure reducing valve structure 2011 and the delivery pipe 2014 are switched, so that the delivery pipe 2014 can be smoothly docked with another set of pressure reducing valve structures 2011 after switching the position, so that after the two pressure reducing valve structures 2011 are replaced, the continuous pressure reducing and delivery operation of the fluid can be met, and the replaced pressure reducing valve structure 2011 can be inspected and maintained, thereby reducing the downtime of the operation and improving the operation efficiency.

[0030] Working principle: When switching the pressure reducing valve structure 2011, the operating head 1024 is rotated in the opposite direction, so that the operating head 1024 drives the screw 1025 to rotate, and the screw 1025 drives the two nuts 1026 to move away from each other, so that the two nuts 1026 respectively drive the adjustment plate 1042 and the movable plate 1033 to move, so that the movable plate 1033 drives the docking rod 1034 to separate from the docking port 2013, and the adjustment plate 1042 drives the insertion rod 1043 to separate from the docking port. 2013, the butt joint pipe 1032 and the connecting pipe 1041 are separated from the pressure reducing valve structure 2011, and at the same time, the adjusting plate 1042 and the movable plate 1033 drive the extrusion plate 1047 and the side plate 1036 to move, and the side plate 1036 and the extrusion plate 1047 are separated from the fixed block 2025, and at the same time, the adjusting plate 1042 drives the movable rod 1046 to move, so that the movable rod 1046 drives the tooth plate 1045 to move, and the tooth plate 1045 drives the tooth valve 1044 to close the connecting pipe 1041; Then, the pressure valve structure is moved to make the movable sleeve 2035 slide on the guide frame 2037, so that the movable sleeve 2035 drives the support plate 2034 to move, so that the second spring 2031 is deformed and turned, and when the second telescopic rod 2032 remains horizontal and moves to the other side again, the second spring 2031 is elastically reset, so that the support plate 2034 drives the sleeve to reset, so that the position of the pressure valve structure and the delivery pipe 2014 is exchanged, so that the delivery pipe 2014 keeps corresponding to the docking pipe 1032 and the connecting pipe 1041; At this time, by rotating the operating head 1024 forward, the screw rod 1025 drives the two nuts 1026 to move relative to each other, so that the adjusting plate 1042 and the movable plate 1033 move relative to each other, so that the docking rod 1034 and the insertion rod 1043 are smoothly inserted into the docking port 2013, and the first cone opening 1037 and the second cone opening 1049 are docked and installed with the inner cone opening 2017. At the same time, the side plate 1036 and the extrusion plate 1047 move the fixed block 2025, so that the fixed block 2025 squeezes the limiting chuck 2023, and the limiting chuck 2023 presses against the cone disk 2015 to maintain stability. At the same time, the connecting rod 1038 and the fixing rod 10410 are inserted into the connecting port 2036, thereby completing the installation operation. At this time, the operation of fluid delivery can be met. When two sets of pressure reducing valve structures 2011 are used, the same method can be used for replacement installation; When the pressure reducing valve structure 2011 needs to be dismantled for maintenance, the limit chuck 2023 can be pulled apart from the cone disk 2015 by the handle 2024, and the pressure reducing valve structure 2011 can be taken out for maintenance.
