Description

Technical Field

[0001] The present invention relates to the technical field of throttle valve surfaces, and in particular to a corrosion-resistant throttle valve surface strengthening treatment device for ultra-high pressure working conditions. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by a pressure regulating valve and is typically used in combination with a solenoid pressure regulating valve. It can be used to remotely control the on / off flow of oil, gas, and water pipelines in hydropower stations. It is commonly used for clamping, control, and lubrication. The valve body is the primary structure of a check valve, and cast iron and stainless steel are the most common materials. Stainless steel valve bodies are more expensive, while cast iron valve bodies have more surface defects and are typically electroplated.

[0003] In the existing technology, the valve body surface is often required to be phosphated first and then subjected to cathode electrolysis. During the surface treatment, multiple equipment are required to form a production line for processing, which is very inconvenient as a whole and has a low degree of integration. In addition, during the treatment, the surface treatment effect is often poor due to the transportation of the valve body. Summary of the Invention

[0038] Preferably, the transmission frame includes a first frame and a second frame, the first frame is a rectangular frame 408f as a whole, and there are two second frames, which are arranged on both sides of the long side of the first frame. When viewed from directly above, the first frame and the two second frames are combined to form a cross shape, and in order to install the processing cylinder 201, the width of the first frame and the second frame are both greater than the width of the processing cylinder 201.

[0039] A rotating member 305 is provided between the first receiving tube 302 , the second receiving tube 303 and the gas discharge tube 304 , and the rotating member 305 drives the movement of the first receiving tube 302 , the second receiving tube 303 and the gas discharge tube 304 .

[0040] Furthermore, the first receiving tube 302 and the second receiving tube 303 are arranged opposite to each other, and two gas discharge tubes 304 are provided and arranged opposite to each other.

[0041] Furthermore, an electrolyte injection pipe 202 extends from the upper end of each gas exhaust tube 304, a first drain pipe 306 is provided at the lower end of each gas exhaust tube 304, a phosphating liquid injection pipe 203 is provided on the first receiving tube 302 and the second receiving tube 303, a second drain pipe 307 is provided at the lower end of the first receiving tube 302 and the second receiving tube 303, and a valve 308 connected to the first drain pipe 306 and the second drain pipe 307 respectively is provided at the lower end of the main processing box 100.

[0043] In this embodiment, the rotating member 305 includes a rotating ring 305a rotatably connected to the transmission frame, a raised ring 305b arranged on the rotating ring 305a, and a recessed groove 305c opened on the rotating ring 305a. There are two raised rings 305b and they are arranged opposite to each other. The two recessed grooves 305c are opened at the two connecting points of the two raised rings 305b.

[0044] Furthermore, abutment blocks 305d abutting against the surface of the rotating ring 305a are provided on the first receiving tube 302, the second receiving tube 303 and the gas exhaust tube 304, and a guide rail 305e for the first receiving tube 302, the second receiving tube 303 and the gas exhaust tube 304 to slide is provided on the transmission frame, and a pull rod 305f is provided between the abutment blocks 305d and the abutment blocks 305d, and one end of each pull rod 305f is hinged to the abutment block 305d, and a slide groove 305g is provided at the other end of each pull rod 305f, and a slider cooperating with the slide groove 305g is provided on the abutment block 305d.

[0045] With the rotation of the rotating ring 305a, the abutment block 305d is always in abutment with the surface of the rotating ring 305a. As the rotating ring 305a rotates, the abutment block 305d will continue to move to the raised ring 305b and the recessed groove 305c. Since the recessed groove 305c is relatively arranged, the raised ring 305b is also relatively arranged, and the rotating ring 305a will perform the following actions when rotating: the recessed groove 305c corresponds to the first receiving tube 302 and the second receiving tube 303. At this time, the first receiving tube 302 and the second receiving tube 303 are in a position close to each other, and the two gas exhaust tubes 304 correspond to the raised ring 305b at this time and are pushed away from each other. At this time, the phosphating liquid injection pipe 203 on the first receiving tube 302 and the second receiving tube 303 injects the phosphating liquid into the processing cylinder 201, and then performs phosphating treatment. After the treatment, the phosphating liquid is discharged using the second liquid discharge pipe 307.

[0046] Then, as the rotating ring 305a continues to rotate, the raised ring 305b corresponds to the first receiving tube 302 and the second receiving tube 303. At this time, the first receiving tube 302 and the second receiving tube 303 are in positions far away from each other, and the two gas exhaust tubes 304 correspond to the recessed groove 305c at this time and are pulled to positions close to each other. The electrolyte injection pipes 202 on the two gas exhaust tubes 304 are connected to the processing cylinder 201, and at this time, the cathode part on the grabbing part cooperates to perform the electrolysis action.

[0047] Furthermore, in this embodiment, the grabbing component 400 includes an end cover 401 rotatably connected to the upper end of the processing cylinder 201, and a grabbing arm 402 arranged in the end cover 401. In this embodiment, the rotation plane of the grabbing arm 402 is vertically arranged, and a grabbing rod 403 is arranged at the bent end of the grabbing arm 402. There are two grabbing rods 403, and they are symmetrically arranged. A retaining ring 404 is provided at the lower end of the two grabbing rods 403, and a side claw 405 is provided on the outside of the retaining ring 404. The side claw 405 is bent from the outside of the connecting ring 407 and extends downward.

[0048] Preferably, a cathode rod 504 is provided at the lower end of the side claw 405, mainly so as to be used as a cathode in subsequent electrolysis operations.

[0049] Furthermore, a clamping plate 406 is provided in the middle section of the grab bar 403. The clamping plate 406 is in the shape of a circular plate. There are two clamping plates 406, one clamping plate 406 is located at the upper end, and the other is located at the lower end. A connecting ring 407 is provided between the two clamping plates 406, and a number of clamping parts 500 are provided on the connecting ring 407. At the same time, a groove group 408 is provided on the connecting ring 407.

[0050] Furthermore, in this embodiment, the clamping member 500 includes a first connecting rod 501 rotatably connected to the side wall of the connecting ring 407, a second connecting rod 502 rotatably connected to the first connecting rod 501, and a grabbing hook 503 arranged at the end of the second connecting rod 502. The rotation planes of the first connecting rod 501 and the second connecting rod 502 are both vertical planes, and the rotation of the first connecting rod 501 can pull the second connecting rod 502. The grabbing hook 503 is bent downward, and the middle part of the grabbing hook 503 is hinged to the connecting ring 407, and an abutment plane is provided at the lower end of the grabbing hook 503.

[0051] As a preferred embodiment, in this embodiment, the groove group 408 includes an upper ring 409a and a lower ring 409b arranged in the connecting ring 407, a first slide groove 408a opened on the upper ring 409a, and a second slide groove 408b opened on the lower ring 409b, the first slide groove 408a is recessed toward the upper position of the upper ring 409a, and the second slide groove 408b is recessed toward the direction of the lower ring 409b, and there are multiple first slide grooves 408a and second slide grooves 408b, and a protrusion is formed between the first slide grooves 408a, and the protrusion corresponds to the second slide groove 408b, so that after the first slide groove 408a and the second slide groove 408b are installed accordingly, a bending path is formed between the first slide groove 408a and the second slide groove 408b.

[0052] Furthermore, a driving block 408c is slidingly connected in the connecting ring 407, and a sliding rod 408h that cooperates with the first sliding groove 408a and the second sliding groove 408b extends from the side wall of the driving block 408c. The driving block 408c drives the sliding rod 408h to move in the groove group 408. Because the sliding rod 408h is restricted by the first sliding groove 408a and the second sliding groove 408b, the driving block 408c will also rotate horizontally.

[0053] Furthermore, a torsion spring is arranged between the driving block 408c and the clamping plate 406, an adjusting rod 408d extends from the lower end of the driving block 408c, a paddle 408e is provided at the lower end of the adjusting rod 408d, a connecting frame is provided at the center position of the retaining ring 404, and two parallel push rods 408g are provided on the connecting frame, and the paddle 408e can extend from the space formed by the two push rods 408g.

[0054] Preferably, a bottom plate 505 is provided inside the processing cylinder 201 to facilitate the grabbing of the grabbing hook 503. When the grabbing rod is pressed down, the grabbing rod will drive the pressing of the retaining ring 404. The side claws 405 on the outside of the retaining ring 404 will first clamp the outside of the bottom plate 505. At the same time, the driving block 408c will move downward. At the same time, the long side of the paddle 408e will not abut against the two supporting rods 408g. At this time, when the grabbing rod moves up, it will drive the clamping plate 406 to move up. The movement of the clamping plate 406 will drive the movement of the first connecting rod 501, and then drive the rotation of the second connecting rod 502, so that the grabbing hook 503 can clamp the lower end of the bottom plate 505.

[0055] Operation process: First, use the grabbing piece to grab the valve body, and then use the rotation of the rotating ring 305a. Because the abutment block 305d is always in abutment with the surface of the rotating ring 305a, and as the rotating ring 305a rotates, the abutment block 305d will continue to move to the raised ring 305b and the recessed groove 305c. Because the recessed groove 305c is relatively set, the raised ring 305b is also relatively set, and then the rotating ring 305a will perform the following actions when rotating: the recessed groove 305c corresponds to the first receiving tube 302 and the second receiving tube 303. At this time, the first receiving tube 302 and the second receiving tube 303 are in a position close to each other, and the two gas exhaust tubes 304 correspond to the raised ring 305b at this time and are pushed away from each other. At this time, the phosphating liquid injection pipe 203 on the first receiving tube 302 and the second receiving tube 303 injects the phosphating liquid into the processing cylinder 201.

[0056] Then, as the rotating ring 305a continues to rotate, the raised ring 305b corresponds to the first receiving tube 302 and the second receiving tube 303. At this time, the first receiving tube 302 and the second receiving tube 303 are in positions far away from each other, and the two gas exhaust tubes 304 correspond to the recessed groove 305c at this time, and are pulled to positions close to each other, and at this time the second liquid discharge pipe 307 is connected to the lower end of the processing cylinder 201, and the electrolyte injection pipe 202 on the two gas exhaust tubes 304 is connected to the processing cylinder 201, and at this time the cathode part on the grabbing part cooperates to perform the electrolysis action.

[0057] After the electrolysis is completed, the electrolyte is discharged, and then the end cover 401 is opened and the valve body is taken out to complete the treatment.

[0058] The above structure arranges phosphating and electrolysis in one device, reducing the processing steps and the need for transportation. The overall structure is compact, and the liquid in the treatment cylinder 201 can be replaced by connecting pipes.
