[0003] Common valve materials mainly include: cast iron, cast steel, stainless steel, copper, etc. These materials greatly improve the anti-rust degree of the valve. However, since the working environment of the valve is always in contact with liquid, especially the water stains and water scales formed after the valve stem is penetrated by the liquid, and after the anti-corrosion materials on the surfaces of the valve stem and valve core are worn, the valve stem and valve core are prone to rust under the action of liquid and air, thereby shortening the service life of the valve and affecting the normal use of personnel. Conventional anti-rust measures, such as adding lubricating oil, require the entire valve to be disassembled, resulting in very inconvenient anti-rust work, making it difficult to perform anti-rust work regularly, and the lubricating oil is unevenly applied, resulting in poor lubrication effect; on the other hand, affected by the working environment of the valve, the valve is prone to water scales, etc., which further induces the generation of rust.

Detailed Implementation Manner

[0021] In the description of this embodiment, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this utility model is usually placed during use. It is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this utility model.

[0022] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "connected", and "linked" should be understood in a broad sense.

[0023] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0024] Refer to Figures 1 to 5 , this embodiment discloses an anti-rust device for ultrasonic metal valves, including a valve body 100. The valve body 100 includes a horizontal pipe 110 and a vertical pipe 120. A valve stem 130 is arranged in the vertical pipe 120. One end of the valve stem 130 is fixedly connected to a valve core, and the other end is fixedly connected to a handwheel 140. The valve core is in sealing sliding contact with the vertical pipe 120. The handwheel 140 is located outside the valve body 100. It is characterized in that: it further includes a lubrication device 200 and an ultrasonic anti-rust device 300; the lubrication device 200 is arranged at one end of the valve stem 130 close to the handwheel 140, and the ultrasonic anti-rust device 300 is arranged outside the valve body 100; the ultrasonic anti-rust device 300 includes an ultrasonic generating component 310 and a telescopic component 320. The ultrasonic generating component 310 is arranged inside the telescopic component 320; when the telescopic component 320 is in a retracted state, the ultrasonic generating component 310 is not in direct contact with the valve body 100; when the telescopic component 320 is in an extended state, the ultrasonic generating component 310 is in direct contact with the valve body 100.

[0025] In the use of this embodiment, the telescopic component 320 can adopt components capable of realizing telescopic movement such as hydraulic components and screw transmission components. When the telescopic component 320 is in the extended state, the ultrasonic generating component 310 is in direct contact with the valve body 100, and power supply to the ultrasonic generating component 310 is started. The ultrasonic waves generated by the ultrasonic generating component 310 are conducted along the outer wall of the pipeline, conducted from the outer wall to the valve core in sealed sliding contact with the inner wall of the pipeline, and then the ultrasonic waves are conducted along the valve core towards the valve stem 130 fixedly connected thereto; on the one hand, the ultrasonic waves can generate strong vibrations and cavitation effects, which can effectively remove dirt, grease, impurities, etc. on the surface of the valve body 100 to keep the surface of the metal valve clean, thereby helping to reduce the occurrence of its corrosion and rust; on the other hand, the ultrasonic waves can be used in combination with an anti-rust coating or anti-rust agent. When the valve body 100 is sprayed with an anti-rust coating or anti-rust agent, the ultrasonic waves help the anti-rust coating or anti-rust agent to be more evenly distributed and penetrate into the tiny pores and gaps on the metal surface, enhancing the anti-rust effect of the valve body 100. Moreover, all the series of transmission media of the ultrasonic waves are solids. Compared with liquid and gas transmission media, the atomic interaction in the solid transmission medium is close and regular, which can more effectively transmit the energy of the ultrasonic waves, with a fast propagation speed and less attenuation. When the telescopic component 320 is in the retracted state, the ultrasonic generating component 310 is not in direct contact with the valve body 100, the power supply to the ultrasonic generating component 310 is ended, and the ultrasonic generating component 310 stops working.

[0026] As a further solution of this embodiment: The ultrasonic anti-rust device 300 further includes a locking component 330, and the locking component 330 is arranged on the outer layer of the telescopic component 320; when the locking component 330 is in the relaxed state, the locking component 330 is not in direct contact with the ultrasonic generating component 310 and the telescopic component 320. At this time, the telescopic component 320 is in the retracted state, and the ultrasonic generating component 310 is not in direct contact with the valve body 100; when the locking component 330 is in the locked state, the locking component 330 is in direct contact with the ultrasonic generating component 310 and the telescopic component 320. At this time, the telescopic component 320 is in the extended state, and the ultrasonic generating component 310 is in direct contact with the valve body 100.

[0027] Adjust the extension or retraction degree of the telescopic component 320 by the locking degree of the locking component 330. When the locking component 330 is in a relaxed state, the locking component 330 is not in direct contact with the ultrasonic generating component 310 and the telescopic component 320, that is, the locking component 330 does not exert a force on the two. At this time, the telescopic component 320 is in a retracted state, the ultrasonic generating component 310 is not in direct contact with the valve body 100, and the ultrasonic generating component 310 is not powered. When the locking component 330 is in a locked state, the locking component 330 is in direct contact with the ultrasonic generating component 310 and the telescopic component 320, and exerts an inward compressive force on the two. The telescopic component 320 starts to extend inward under the inward compressive force, and the ultrasonic generating component 310 inside the telescopic component 320 starts to move inward under the inward compressive force and finally comes into direct contact with the valve body 100. After that, the ultrasonic generating component 310 is powered.

[0028] As a further solution of this embodiment: The ultrasonic anti-rust device 300 further includes an arc base 340 and a shock-absorbing component 350; the arc base 340 is fixedly connected to the transmitting end of the ultrasonic generating component 310, and the arc base 340 is located inside the telescopic component 320; the shock-absorbing component 350 is fixedly connected to the receiving end of the ultrasonic generating component 310, and the shock-absorbing component 350 is located outside the telescopic component 320; when the locking component 330 is in a locked state, the arc base 340 is in direct contact with the valve body 100, and the shock-absorbing component 350 is in direct contact with the locking component 330. Further, the bottom of the arc base 340 adopts an arc with a larger radian.

[0029] When the locking component 330 is in a locked state, the ultrasonic generating component 310 and the telescopic component 320 should be in direct contact with the locking component 330, and under the inward compressive force of the locking component 330, the ultrasonic generating component 310 is in direct contact with the valve body 100; but because the arc base 340 is fixedly connected to the transmitting end of the ultrasonic generating component 310 and the shock-absorbing component 350 is fixedly connected to the receiving end of the ultrasonic generating component 310, the shock-absorbing component 350 is in direct contact with the locking component 330 and the arc base 340 is in direct contact with the valve body 100; the advantages of such a design are: on the one hand, through the shock-absorbing component 350, the rigid contact between the locking component 330 and the telescopic component 320 and the ultrasonic generating component 310 is avoided, reducing the damage of the three components due to long-term locking, and on the other hand, the reaction force generated by the ultrasonic generating component 310 during operation on the locking component 330 under the locked state can be reduced, thereby improving the service life of the locking component 330, the ultrasonic generating component 310, and the telescopic component 320; by setting the arc base 340, the ultrasonic generating component 310 can better fit the valve body 100, improving the effective conduction range of ultrasonic waves.

[0030] As a further solution of this embodiment: The ultrasonic generating component 310 is symmetrically arranged inside the telescopic component 320. The telescopic component 320 includes a first limiting plate 321, a first telescopic spring 322, a first circular ring frame 323, and an arc support frame 324. One end of the first telescopic spring 322 is fixedly connected to the first limiting plate 321, and the other end is fixedly connected to the first circular ring frame 323. The first ultrasonic generating component 310 is located inside the first telescopic spring 322 and the first circular ring frame 323. The arc support frame 324 is symmetrically arranged outside the first circular ring frame 323, and the first circular ring frame 323 is detachably connected to the arc support frame 324. The first limiting plate 321 is in direct contact with the emitting end of the ultrasonic generating component 310, and the first limiting plate 321 is provided with a circular hole to facilitate its arrangement between the first ultrasonic generating component 310 and the arc base 340.

[0031] When the model of the valve body 100 changes significantly, the arc support frame 324 can be replaced at this time to adapt to different models of the valve body 100. When installing the ultrasonic generating component 310, the ultrasonic generating component 310 is installed into the first telescopic spring 322 through the first circular ring frame 323, and then the emitting end of the ultrasonic generating component 310 is extended out from the circular hole of the first limiting plate 321. After that, the arc base 340 is fixedly connected to the emitting end of the ultrasonic generating component 310. When the locking component 330 is in a relaxed state, the locking component 330 is not in direct contact with the shock-absorbing component 350, the first telescopic spring 322 is in a retracted state, and the first limiting plate 321 limits the ultrasonic generating component 310 and the arc base 340 fixedly connected thereto to ensure that the two are not in direct contact with the valve body 100, and the ultrasonic generating component 310 is not powered. When the locking component 330 is in a locked state, the locking component 330 compresses the shock-absorbing component 350 inward, thereby pushing the ultrasonic generating component 310 to move inward. The first limiting plate 321 and the arc base 340 also move inward under the push of the ultrasonic generating component 310. The first limiting plate 321 prevents the ultrasonic generating component 310 from falling off inside the telescopic component 320, the arc base 340 is in direct contact with the valve body 100, and the ultrasonic generating component 310 starts to be powered.

[0032] As a further solution of this embodiment: the locking component 330 includes a fixed ring body 331, a movable ring body 332, a ratchet 333, a moving component 334, and a first return spring 335; the fixed ring body 331 and the movable ring body 332 are rotationally connected; the fixed ring body 331 is provided with a slide groove, and the first return spring 335 and a slidable moving component 334 are arranged in the slide groove, one end of the first return spring 335 is fixedly connected to the moving component 334, and the other end is fixedly connected to the inner surface of the slide groove, and the moving component 334 and the ratchet 333 are unidirectionally rotationally connected; the movable ring body 332 is provided with a sawtooth 336; when the first return spring 335 is in an extended state, the fixed ring body 331 and the movable ring body 332 form a closed loop, and the sawtooth 336 is in direct contact with the ratchet 333; when the first return spring 335 is in a retracted state, the sawtooth 336 and the ratchet 333 do not come into contact.

[0033] When the locking component 330 is in a relaxed state, the fixed ring body 331 and the movable ring body 332 do not form a closed loop, and the saw teeth 336 of the movable ring body 332 do not directly contact the ratchet 333 . When the locking component 330 is in the locked state, the fixed ring body 331 and the movable ring body 332 form a closed loop, and the movable ring body 332 continues to rotate around the fixed ring body 331 to reduce the closed area of ​​the closed loop formed by the two. The movable component 334 is pushed by the first return spring 335 to approach the movable ring body 332, and the ratchet 333 on the movable component 334 is in direct contact with the saw teeth 336 on the movable ring body 332. The ratchet 333 starts to rotate under the push of the saw teeth 336, and the closed area of ​​the closed loop formed by the movable ring body 332 and the fixed ring body 331 continues to decrease until the arc base 340 is tightly fitted with the valve body 100. At this time, the locking movement is stopped. Since the ratchet 333 and the movable component 334 adopt unidirectional rotation, the ratchet 333 can prevent the saw teeth 336 from moving in the opposite direction, that is, prevent the movable ring body 332 from moving in the opposite direction, to ensure that there is no looseness in the locked state. When it is necessary to open the locking component 330 in the locked state, the movable component 334 is pushed along the retraction direction of the first return spring 335 to separate the ratchet 333 from the serration 336, and then the movable ring body 332 is rotated outward around the fixed ring body 331 so that the two cannot form a closed loop, thereby opening the locking component 330.

[0034] As a further solution of this embodiment: an oil pipe 131 is opened inside the valve stem 130 , and an oil hole 132 is opened at the connection between the valve stem 130 and the valve core. The oil hole 132 is connected to the oil pipe 131 , and the oil pipe 131 is connected to the lubrication device 200 .

[0035] When this embodiment is in use, the rust preventive oil stored in the lubricating device 200 is injected into the inside of the valve stem 130 along the oil passage pipe 131. The rust preventive oil flows along the oil passage pipe 131 to the oil passage hole 132, and then flows from the oil passage hole 132 to the connection between the valve stem 130 and the valve core, thereby preventing rust here. Moreover, under the action of ultrasonic waves, the rust preventive oil can better penetrate into the small gaps at the connection between the valve stem 130 and the valve core, improving the rust prevention effect.

[0036] As a further solution of this embodiment: The lubricating device 200 includes an oil storage barrel 210, a circular barrel cover 220, a compression cover 230, and a second return spring 240. The oil storage barrel 210 is screwed to the circular barrel cover 220. One end of the second return spring 240 is fixedly connected to the circular barrel cover 220, and the other end is fixedly connected to the compression cover 230. The compression cover 230 is in sealed sliding contact with the inner side surface of the oil storage barrel 210. A drain hole 211 is provided at the bottom of the oil storage barrel 210, and the drain hole 211 is communicated with the oil passage pipe 131. An inner barrel 212 is provided on the inner surface of the bottom of the oil storage barrel 210 around the drain hole 211. A through hole is provided at the bottom side of the inner barrel 212. An inner cover 231 is provided at the bottom of the compression cover 230, and a pressing rod 232 is provided at the top of the compression cover 230. When the second return spring 240 is in a compressed state, the compression cover 230 is close to the circular barrel cover 220, and the inner cover 231 does not directly contact the inner barrel 212. When the second return spring 240 is in an extended state, the compression cover 230 is close to the bottom of the oil storage barrel 210, and the inner cover 231 completely covers the inner barrel 212, including its side through hole.

[0037] When the oil storage barrel 210 is filled with oil, the second return spring 240 is in a compressed state, and the compression cover 230 is close to the circular barrel cover 220 in the oil storage barrel 210. As the rust preventive oil in the oil storage barrel 210 flows from the oil discharge hole 211 in the built-in barrel 212 to the through oil pipe 131, the rust preventive oil in the oil storage barrel 210 gradually decreases, the oil level gradually drops, and the compression cover 230 also gradually moves away from the circular barrel cover 220 as the oil level drops, and the second return spring 240 is gradually stretched. When the oil level in the oil storage barrel 210 drops to a certain extent, the second return spring 240 is in an extended state. At this time, the built-in barrel 212 cover on the compression cover 230 blocks the built-in barrel 212 in the oil storage barrel 210, and the remaining rust preventive oil in the oil storage barrel 210 no longer flows into the oil discharge hole 211 but remains in the oil storage barrel 210, stopping the oil supply to the valve body 100. Therefore, it is necessary for personnel to conduct regular inspections. When the staff lifts the compression cover 230 by pressing the lever 232, the built-in barrel 212 is completely separated from the built-in cover 231, and the rust preventive oil in the oil storage barrel 210 continues to flow into the through oil pipe 131 through the oil discharge hole 211. When the staff releases the pressing lever 232, the compression cover 230 begins to sink under its own gravity, but due to the stretching effect of the second return spring 240, the sinking speed of the compression cover 230 is relatively slow, thus realizing the timed oil discharge of the lubrication device 200.
