Description

Technical Field

[0001] The utility model belongs to the field of regulating valves, and in particular relates to a high-pressure resistant oil pressure regulating valve. Background Art

[0002] A regulating valve, also known as a control valve, is a final control element in industrial automation process control that receives control signals from a regulating control unit and uses power to alter process parameters such as flow, pressure, temperature, and liquid level. It typically consists of an actuator and a valve. Regulating valves can be categorized by stroke characteristics as linear or angular. Based on the power used by their actuators, they can be divided into pneumatic, electric, and hydraulic control valves. Their functions and characteristics can be categorized into linear, equal percentage, and parabolic characteristics.

[0003] When the existing oil pressure regulating valve regulates the pressure of the fluid before and after the valve, the valve stem will move up and down rapidly due to the sudden change in the pressure of the fluid before or after the valve, which will cause the regulating valve itself to vibrate easily. The connection between the regulating valve and the pipeline will become loose due to the influence of long-term vibration, which will lead to leakage. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high-pressure resistant oil pressure regulating valve.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A high-pressure oil pressure regulating valve comprises an oil pressure regulating valve body, a flange docking ring, and a special-shaped frame. Both ends of the oil pressure regulating valve body are provided with flange docking rings for docking with external flanges. External pipes are connected to the outsides of the two external flanges. Special-shaped frames for reinforcing the flange docking rings and the external flanges are symmetrically fixed on both sides of the oil pressure valve body. The outsides of the two flange docking rings are both sleeved with inner contact rings.

[0007] The side end of each special-shaped frame is threadedly connected to a fastening bolt, and the side end of the fastening bolt is rotatably connected to the connecting ring through a bearing. The connecting ring is fixedly connected to the outer contact ring, and a reinforcement area for reinforcing the flange docking ring and the external flange is provided between the outer contact ring and the inner contact ring.

[0008] Optionally, anti-slip pads are fixed to the opposite surfaces of the outer and inner contact rings.

[0009] Optionally, the flange docking ring and the outer sleeve of the external flange are provided with an expansion sealing airbag, a gas nozzle is fixed on one side of the expansion sealing airbag, and one side of the gas nozzle passes through the special-shaped frame through a conduit and is connected to one end of the pressure gauge.

[0010] Optionally, the upper ends of the two special-shaped frames located on the upper side are hinged with fixing covers through connecting pieces, and the upper ends of the fixing covers and the lower ends of the special-shaped frames located on the lower side are provided with screw holes for screwing fixing bolts.

[0011] Optionally, a reinforcement pad is provided on the inner side of the inflatable sealing airbag, and a film-coated pressure sensor is provided inside the reinforcement pad. The film-coated pressure sensor passes through the special-shaped frame and is connected to the controller.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] The utility model reinforces the external flange installed on the flange docking ring of the oil pressure regulating valve body through the special-shaped frame, the inner contact ring and the outer contact ring, so that the connection will not loosen when facing high-pressure gas or liquid. After the expansion sealing airbag is injected with air in the later stage, the expansion sealing airbag will expand on the inner side of the special-shaped frame and the inner contact ring and the outer contact ring, thereby performing auxiliary sealing to avoid leakage.

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] See also Figures 1 to 6 The utility model provides a technical solution: a high-pressure oil pressure regulating valve, comprising an oil pressure regulating valve body 1, a flange docking ring 3, and a special-shaped frame 5. Both ends of the oil pressure regulating valve body 1 are provided with a flange docking ring 3 that is docked with an external flange 2. External pipes 4 are connected to the outsides of the two external flanges 2. Special-shaped frames 5 for reinforcing the flange docking ring 3 and the external flange 2 are symmetrically fixed on both sides of the oil pressure valve body. The outsides of the two flange docking rings 3 are both sleeved with inner contact rings 6.

[0028] The side ends of each special-shaped frame 5 are threadedly connected with a fastening bolt 7, and the side ends of the fastening bolt 7 are rotatably connected to the connecting ring 8 through a bearing. The connecting ring 8 is fixedly connected to the outer contact ring 9. A reinforcement area for reinforcing the flange docking ring 3 and the external flange 2 is provided between the outer contact ring 9 and the inner contact ring 6. Considering that when the pressure of the fluid before and after the existing oil pressure regulating valve is adjusted, the valve stem will move up and down quickly due to the sudden change of the fluid pressure before or after the valve, which will cause the regulating valve itself to vibrate easily, making the connection between the regulating valve and the pipeline affected. In order to prevent the loosening caused by long-term vibration and thus the occurrence of leakage, the utility model strengthens the external flange 2 installed with the flange docking ring 3 of the oil pressure regulating valve body 1 through the special-shaped frame 5, the inner contact ring 6 and the outer contact ring 9, so that the connection will not loosen when facing the high-pressure gas or liquid. After the expansion sealing airbag 12 is injected with air at a later time, the expansion sealing airbag 12 will expand on the inner side of the special-shaped frame 5 and the inner contact ring 6 and the outer contact ring 9, thereby performing auxiliary sealing to avoid leakage.

[0029] Among them, anti-slip pads 11 are fixed on the opposite surfaces of the outer contact ring 9 and the inner contact ring 6. The provision of the anti-slip pads 11 increases the friction between the outer contact ring 9 and the inner contact ring 6 and the flange docking ring 3 and the external flange 2.

[0030] Among them, the flange docking ring 3 and the external flange 2 are sheathed with an inflatable sealing airbag 12, and a gas nozzle 13 is fixed on one side of the inflatable sealing airbag 12, and one side of the gas nozzle 13 passes through the special-shaped frame 5 through a conduit and is connected to one end of the pressure gauge 14. By setting the inflatable sealing airbag 12, the contact surface of the external flange 2 and the flange docking ring 3 plays an auxiliary sealing role, further improving the sealing performance of the flange connection ring 8 and the external flange to avoid the impact of the transported high-pressure gas or high-pressure liquid on the flange connection and causing leakage.

[0031] Among them, the upper ends of the two special-shaped frames 5 located on the upper side are hinged with fixed covers 16 through connecting parts 15, and the upper ends of the fixed covers 16 and the lower ends of the special-shaped frames 5 located on the lower side are provided with screw holes for screwing fixing bolts. The setting of the fixing bolts plays a role in fixing the fixing covers 16 and the special-shaped frames 5.

[0032] Among them, a reinforcement pad 17 is provided on the inner side of the expansion sealing airbag 12, and a film-coated pressure sensor 18 is provided inside the reinforcement pad 17. The film-coated pressure sensor 18 passes through the special-shaped frame 5 and is connected to the controller 19. The controller 19 is internally provided with a remote communication module, a processing chip and a storage module. By setting the film-coated pressure sensor 18 and cooperating with the controller 19, a leak detection function is played between the external flange 2 and the flange docking ring 3. When the flange connection leaks, the gas or liquid will cause an impact on the expansion sealing airbag. At this time, the film-coated pressure sensor 18 obtains the pressure analog quantity, and after being processed by the processing chip inside the controller 19, it will be sent to the maintenance terminal of the remote device through the remote communication module, so that the remote device personnel can notify the local personnel of the leakage.

[0033] Among them, the front end of the oil pressure regulating valve body 1 is fixed with an elastic metal clip 20 by screws, and the two end ends of the elastic metal clip 20 are rotatably connected with a resistance wheel 21, and the resistance wheels 21 of the two elastic metal clips 20 are in resistance with the surface of the inflated balloon 10. By setting the elastic metal clip 20, the inflated balloon 10 is fixed, and the inflated balloon 10 can be used to inflate the expansion sealing airbag 12.

[0034] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
