Description

Technical Field

[0001] The present invention relates to the technical field of vacuum compensators, and more specifically, to a vacuum compensator with an adaptive adjustment function. Background Art

[0002] A vacuum compensator is a device used to compensate for the volume change of a vacuum system caused by temperature changes. The main function of a vacuum compensator is to balance the internal and external pressures of the vacuum system and ensure the normal operation of the system. In a vacuum system, as the temperature changes, the volume of the gas also changes, which will affect the vacuum degree and gas flow. Therefore, it is necessary to solve this problem through a vacuum compensator. Vacuum compensators can be divided into corrugated vacuum compensators, hinge expansion vacuum compensators, etc.

[0003] However, when installing the current hinge vacuum compensator, fixing the two flanges to the opposite ends of the two pipes can complete the installation. When the pressure inside the two pipes changes, the corrugated pipe part of the compensator will twist, and the rotating plate on one of the flanges will also rotate with the rotating shaft as the fulcrum. There is no limit component in the hinge structure formed by the rotating plates on the two flanges. When the pressure inside the two pipes changes too much, the twisting amplitude of the corrugated pipe will also increase. Without a limit component, the corrugated pipe is prone to damage, resulting in leakage of the conveyed medium; moreover, the rotating shaft on the hinge structure needs to rotate with the rotating plate, and the rotating part between the rotating shaft and the rotating plate will cause wear to both of them due to long-term rotation. There is no lubrication mechanism on the rotating shaft to lubricate the rotating part to reduce wear. When the wear is large, it will not only affect the protection of the corrugated pipe, but also cause abnormal noise; a flow guide cylinder is installed inside the corrugated pipe between the two flanges. The flow guide cylinder is made of metal and welded to one end of the corrugated pipe. When the corrugated pipe twists, the flow guide cylinder will also move. When the flow guide cylinder moves, it will deform, resulting in an increase in the gap between the corrugated pipe and the flow guide cylinder. Impurities in the medium will enter between the corrugated pipe and the flow guide cylinder, which is difficult to clean, affects the twisting of the corrugated pipe, and reduces the compensation function. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a vacuum compensator with an adaptive adjustment function.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: A vacuum compensator with an adaptive adjustment function, including two flange plates and a compensation mechanism installed between the two flange plates.

Connecting pipes are installed on the opposite sides of the two flange plates. Fixed slots are provided at the opposite ends of the two connecting pipes, and a corrugated pipe is welded between the two fixed slots. A sealing ring is provided between the connecting pipe and the corrugated pipe; The rotating mechanism includes two groups of fixed seats. Two fixed seats are relatively fixedly connected to the outer walls of the two connecting pipes. Rotating plates are fixedly connected to both of the two fixed seats on one of the connecting pipes, and rotating frames are fixedly connected to both of the two fixed seats on the other connecting pipe. The rotating plates and the rotating frames on the same side are rotatably connected through a rotating shaft; The limiting mechanism includes two groups of limiting holes. A plurality of limiting holes are opened on the two rotating plates. Two clamping columns are inserted between two opposite limiting holes on the same rotating plate. A limiting rod is slidably connected between the two clamping columns. A bidirectional lead screw is threadedly connected between the two clamping columns on the same side. The limiting hole at the center of the rotating plate and the center of the rotating shaft are located on the same straight line.

[0006] Specifically, the two groups of the limiting holes are arranged in an arc array, and the distance between any one of the limiting holes and the rotating shaft is equal.

[0007] Specifically, the limiting mechanism further includes a rotating block. Rotating blocks are fixedly connected to the centers of the two bidirectional lead screws. The rotating block has a hexagonal prism structure.

[0008] Specifically, there are two rotating frames in the same group, and the rotating plate is located at the center of the two rotating frames.

[0009] Specifically, the oil outlet mechanism includes a housing. Housings are fixedly connected to the two rotating plates. Diversion holes located at the bottom of the housing are opened on the two rotating plates. The two diversion holes are located at the top of the two rotating shafts. Sponge pads are placed inside the two housings. Pressing rods located on the top of the sponge pads are slidably connected inside the two housings. Springs are clamped between the pressing rods and the housings.

[0010] Specifically, the oil outlet mechanism further includes balls. Balls are rotatably connected to the tops of the two pressing rods.

[0011] Specifically, the pressing mechanism includes two mounting seats. Mounting seats are fixedly connected to the inner sides of the two rotating frames. Fixed rods are fixedly connected to the two mounting seats. Pressing plates are fixedly connected to the two fixed rods. The pressing plates and the fixed rods form an L-shaped structure, and the two pressing plates are located at the top of the housing.

[0012] Specifically, the oil injection mechanism includes an oil leakage pipe and oil leakage ports. Oil leakage ports are opened on the sides of the two housings. An oil leakage pipe in a U-shaped structure is connected between the two oil leakage ports. Two oil injection holes are symmetrically arranged at the center of the oil leakage pipe.

[0013] Specifically, the oil injection mechanism further includes a protective sleeve. A protective sleeve is slidably connected to the oil leakage pipe. The length of the protective sleeve is greater than the distance between the two oil injection holes.

[0014] Specifically, the diversion mechanism includes a mounting ring. A mounting ring is fixedly connected to the inner wall edge of one of the connecting pipes. A slot is opened on the mounting ring. A connecting cylinder is inserted into the slot. A limiting groove is provided on the mounting ring. A snap ring corresponding to the limiting groove is sleeved on the connecting cylinder. A sponge ring is provided between the end of the connecting cylinder and the other connecting pipe. The connecting cylinder is made of rubber material.

[0015] The beneficial effects of the present invention are as follows: (1) For a vacuum compensator with an adaptive adjustment function according to the present invention, a rotating mechanism is provided between the two connecting pipes. When the bellows twists and is in a compensation state due to a change in internal pressure, the rotating plate remains stationary, and the rotating frame rotates with the rotating shaft as the fulcrum. The twisting amplitude of the bellows is proportional to the rotation angle of the rotating frame. A limiting mechanism is provided on the two rotating plates. The distance between the two clamping columns can be adjusted by holding the limiting rod and rotating the bidirectional lead screw, so that the clamping columns are inserted into the two opposite limiting holes. Since the limiting holes are symmetrically distributed with respect to the rotating shaft, when the bidirectional lead screw is rotated, the clamping columns are limited by the limiting rod, and the moving distances of the two clamping columns are equal. After the clamping columns are engaged with the limiting holes, the rotation of the rotating frame is limited. The rotation range of the rotating frame can be limited as needed to avoid excessive rotation amplitude, that is, excessive compensation range, which may cause serious damage to the bellows and lead to medium leakage.

[0016] (2) For a vacuum compensator with an adaptive adjustment function according to the present invention, an oil outlet mechanism is provided on the rotating plate. The oil outlet mechanism is communicated with the rotating shaft, and an oil injection mechanism is installed between the two oil outlet mechanisms. Lubricating oil can be added through two oil injection holes and flow to two oil leakage ports, and then flow to the sponge pad inside the housing through the oil leakage ports. When the pressure inside the bellows changes greatly, the rotating frame rotates counterclockwise. At this time, the pressing plate presses the pressing rod and the spring contracts. Further, the pressing rod presses the sponge pad, and the lubricating oil overflows and flows to the position of the rotating shaft through the diversion hole to lubricate the rotating shaft and the rotating frame, reduce wear, and avoid abnormal noise caused by excessive wear between the rotating frame and the rotating shaft and affect the protection of the bellows.

[0017] (3) For a vacuum compensator with an adaptive adjustment function according to the present invention, a diversion mechanism located inside the bellows is installed on one of the connecting pipes. The slot on the installation ring is used for installing the connecting cylinder. When the bellows twists, due to the elasticity of the connecting cylinder, it will also twist, which can prevent deformation and inability to reset, resulting in residues in the conveyed medium entering the inside of the bellows and affecting its twisting. When the connecting cylinder needs to be replaced, the snap ring on its outer wall can be disassembled and the connecting cylinder can be pulled out for convenient replacement of the connecting cylinder.

Detailed implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0022] Such as Figures 1-9As shown in the figure, a vacuum compensator with an adaptive adjustment function according to the present invention includes two flange plates 1 and a compensation mechanism 2 installed between the two flange plates 1. Two rotating mechanisms 3 are installed on the compensation mechanism 2, two limiting mechanisms 4 are installed on both of the two rotating mechanisms 3, two oil outlet mechanisms 7 are installed on both of the two rotating mechanisms 3, two pressing mechanisms 5 are installed on both of the two rotating mechanisms 3, an oil injection mechanism 6 is installed between the two oil outlet mechanisms 7, and a diversion mechanism 8 is installed inside the compensation mechanism 2; the compensation mechanism 2 includes two connecting pipes 201, connecting pipes 201 are installed on the opposite sides of the two flange plates 1, fixed slots 204 are provided at the opposite ends of the two connecting pipes 201, a corrugated pipe 202 is welded between the two fixed slots 204, and a sealing ring 203 is provided between the connecting pipe 201 and the corrugated pipe 202; the rotating mechanism 3 includes two groups of fixed seats 301, two fixed seats 301 are relatively fixedly connected to the outer walls of the two connecting pipes 201, rotating plates 302 are fixedly connected to both of the two fixed seats 301 on one of the connecting pipes 201, rotating frames 304 are fixedly connected to both of the two fixed seats 301 on the other connecting pipe 201, and the rotating plates 302 and the rotating frames 304 on the same side are rotatably connected through a rotating shaft 303; the limiting mechanism 4 includes two groups of limiting holes 405, a plurality of limiting holes 405 are provided on the two rotating plates 302, two clamping columns 403 are inserted between two opposite limiting holes 405 on the same rotating plate 302, a limiting rod 404 is slidably connected between the two clamping columns 403, a bidirectional lead screw 401 is threadedly connected between the two clamping columns 403 on the same side, and the limiting hole 405 at the center of the rotating plate 302 and the center of the rotating shaft 303 are located on the same straight line; the two groups of limiting holes 405 are arranged in an arc array, and the distance between any one of the limiting holes 405 and the rotating shaft 303 is equal; the limiting mechanism 4 further includes a rotating block 402, rotating blocks 402 are fixedly connected to the centers of the two bidirectional lead screws 401, and the rotating block 402 has a hexagonal prism structure; two of the same group of rotating frames 304 are provided, and the rotating plate 302 is located at the center of the two rotating frames 304; Since the rotating plates 302 on two of the fixed seats 301 are rotatably connected to the rotating frames 304 on the other two fixed seats 301 through the rotating shafts 303, when the internal pressure of the bellows 202 changes, the rotating frame 304 will rotate clockwise or counterclockwise with the rotating shaft 303 as the fulcrum, thus protecting the bellows 202. The rotating frame 304 can be limited by the clamping posts 403 to adjust the twisting range of the bellows 202, thereby protecting the bellows 202. When adjusting the movement range of the rotating frame 304, the limiting rod 404 can be held, and the rotating block 402 on the bidirectional lead screw 401 can be rotated. After the rotating block 402 rotates, the bidirectional lead screw 401 is rotated. Since the clamping post 403 is limited by the limiting rod 404, when the bidirectional lead screw 401 rotates, the two clamping posts 403 move relatively or away from each other. As long as the distance between the two clamping posts 403 is adjusted to match the two symmetric limiting holes 405, the two clamping posts 403 can be inserted into the two opposite limiting holes 405. Tighten the bidirectional lead screw 401 again to prevent the clamping post 403 from falling out of the limiting hole 405. The distance between the ends of the two rotating frames 304 and the clamping post 403 is the maximum range of rotation of the rotating frame 304. This range can be adjusted to adjust the twisting amplitude of the bellows 202, that is, to adjust the compensation range of the bellows 202, and prevent the bellows 202 from being severely damaged and causing medium leakage.

[0023] Specifically, referring to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the oil outlet mechanism 7 includes a housing 701. The housing 701 is fixedly connected to both of the two rotating plates 302. A diversion hole 706 is provided at the bottom of the housing 701 on both of the two rotating plates 302. The two diversion holes 706 are located at the top of the two rotating shafts 303. A sponge pad 705 is placed inside each of the two housings 701. A pressure rod 702 is slidably connected inside each of the two housings 701 and is located on top of the sponge pad 705. A spring 703 is clamped between the pressure rod 702 and the housing 701. The oil outlet mechanism 7 further includes a ball 704. The ball 704 is rotatably connected to the top of each of the two pressure rods 702. The pressing mechanism 5 includes two mounting seats 503. The mounting seats 503 are fixedly connected to the inner sides of the two rotating frames 304. A fixing rod 501 is fixedly connected to each of the two mounting seats 503. A pressing plate 502 is fixedly connected to each of the two fixing rods 501. The pressing plate 502 and the fixing rod 501 form an L-shaped structure, and the two pressing plates 502 are located on top of the housing 701. The oil injection mechanism 6 includes an oil leakage pipe 601 and an oil leakage port 603. An oil leakage port 603 is provided on the side of each of the two housings 701. The two oil leakage ports 603 are connected by an oil leakage pipe 601 having a U-shaped structure. Two oil injection holes 604 are symmetrically provided at the center of the oil leakage pipe 601. The oil injection mechanism 6 further includes a protective sleeve 602. The protective sleeve 602 is slidably connected to the oil leakage pipe 601, and the length of the protective sleeve 602 is greater than the distance between the two oil injection holes 604. Since there will be wear between the rotating shaft 303 and the rotating frame 304 after long-term rotation, lubrication is required for the two. Slide the protective sleeve 602 located on the oil leakage pipe 601 to expose the two oil injection holes 604. After the oil injection is completed, the protective sleeve 602 can protect the oil injection holes 604 to prevent dust from entering. Add lubricating oil into the two oil injection holes 604. The lubricating oil will flow into the two oil leakage ports 603 and finally flow from the oil leakage ports 603 into the two housings 701. The lubricating oil flowing into the housing 701 is absorbed by the sponge pad 705. If the right end of the corrugated pipe 202 twists upward, at this time, the rotating frame 304 will rotate counterclockwise with the rotating shaft 303 as the fulcrum. After the rotating frame 304 rotates counterclockwise, it drives the fixing rod 501 to make a circular motion with the rotating shaft 303 as the center. After the fixing rod 501 rotates a certain angle, the pressing plate 502 presses the pressure rod 702 and the spring 703 contracts. Further, the pressure rod 702 presses the sponge pad 705, and the lubricating oil inside the sponge pad 705 is squeezed out and flows from the diversion hole 706 to the space between the rotating shaft 303 and the rotating frame 304 to lubricate the two, reduce wear, improve the protection effect on the corrugated pipe 202, and avoid abnormal noise. After the rotating frame 304 resets, the pressure rod 702 resets and no more oil will be discharged for lubrication to avoid waste. Only need to add lubricating oil to the oil leakage pipe 601 regularly.

[0024] Specifically, referring to Figure 2 andFigure 3 As shown, the flow guiding mechanism 8 includes a mounting ring 801. The inner wall edge of one of the connecting pipes 201 is fixedly connected with the mounting ring 801. A slot 804 is formed in the mounting ring 801. A connecting cylinder 802 is inserted into the slot 804. A limiting groove 805 is provided on the mounting ring 801. A snap ring 806 corresponding to the limiting groove 805 is sleeved on the connecting cylinder 802. A sponge ring 803 is provided between the end of the connecting cylinder 802 and the other connecting pipe 201. The connecting cylinder 802 is made of rubber material; When installing the connecting cylinder 802, insert one end of the connecting cylinder 802 into the slot 804 inside the mounting ring 801, and then sleeve the snap ring 806 on the outside of the connecting cylinder 802. The connecting cylinder 802 deforms, and the snap ring 806 can snap the connecting cylinder 802 into the limiting groove 805 outside the mounting ring 801, improving the fixing effect on the connecting cylinder 802. Moreover, the end of the mounting ring 801 is the medium inlet end. A sponge ring 803 is provided between the other end of the connecting cylinder 802 and the connecting pipe 201, which can increase the sealing performance when the connecting cylinder 802 twists, and prevent impurities in the medium from entering between the corrugated pipe 202 and the connecting cylinder 802 and affecting the twisting of the corrugated pipe 202.

[0025] When the present invention is in use, first, when installing the entire device, connect the two flange plates 1 to the two pipe joints. It should be noted that the flange plate 1 at one end of the installation ring 801 is connected to the stationary pipe, and the other flange plate 1 is connected to the other movable pipe. One end of the installation ring 801 is the medium inlet end, and the unfixed end of the connecting cylinder 802 is the medium outlet end, which can prevent impurities in the medium from entering the gap between the corrugated pipe 202 and the connecting cylinder 802 and affecting the torsion of the corrugated pipe 202. Since the rotating plates 302 on two of the fixed seats 301 are rotatably connected to the rotating frames 304 on the other two fixed seats 301 through the rotating shafts 303, when the internal pressure of the corrugated pipe 202 changes, the rotating frame 304 will rotate clockwise or counterclockwise with the rotating shaft 303 as the fulcrum, thus protecting the corrugated pipe 202. The movement range of the rotating frame 304 can be limited by the clamping column 403 to adjust the torsion range of the corrugated pipe 202, thereby protecting the corrugated pipe 202. When adjusting the movement range of the rotating frame 304, hold the limiting rod 404 and rotate the rotating block 402 on the bidirectional screw rod 401. After the rotating block 402 rotates, the bidirectional screw rod 401 is rotated. Since the clamping column 403 is limited by the limiting rod 404, when the bidirectional screw rod 401 rotates, the two clamping columns 403 move relatively or away from each other. Just adjust the distance between the two clamping columns 403 to match the two symmetrical limiting holes 405, and then insert the two clamping columns 403 into the two opposite limiting holes 405. Tighten the bidirectional screw rod 401 again to prevent the clamping column 403 from falling out of the limiting hole 405. The distance between the end of the two rotating frames 304 and the clamping column 403 is the maximum range of rotation of the rotating frame 304. This range can be adjusted to adjust the torsion amplitude of the corrugated pipe 202, that is, to adjust the compensation range of the corrugated pipe 202, and avoid serious damage to the corrugated pipe 202 resulting in medium leakage; Then, when installing the connecting cylinder 802, insert one end of the connecting cylinder 802 into the slot 804 inside the installation ring 801, and then sleuth the snap ring 806 onto the outside of the connecting cylinder 802. The connecting cylinder 802 deforms, and the snap ring 806 can buckle the connecting cylinder 802 into the limiting slot 805 outside the installation ring 801 to improve the fixing effect on the connecting cylinder 802. One end of the installation ring 801 is the medium inlet end, and a sponge ring 803 is provided between the other end of the connecting cylinder 802 and the connecting pipe 201, which can increase the sealing performance when the connecting cylinder 802 twists and prevent impurities in the medium from entering between the corrugated pipe 202 and the connecting cylinder 802 and affecting the torsion of the corrugated pipe 202; Finally, since there will be wear between the rotating shaft 303 and the rotating frame 304 after long-term rotation, it is necessary to lubricate the two. Slide the protective sleeve 602 on the oil leakage pipe 601 to expose the two oil injection holes 604. After the oil injection is completed, the protective sleeve 602 can protect the oil injection holes 604 to prevent dust from entering. Add lubricating oil into the two oil injection holes 604. The lubricating oil will flow into the two oil leakage ports 603 and finally flow into the two outer shells 701 from the oil leakage ports 603. The lubricating oil flowing into the inner part of the outer shell 701 is absorbed by the sponge pad 705. If the right end of the corrugated pipe 202 twists upward, at this time the rotating frame 304 will rotate counterclockwise with the rotating shaft 303 as the fulcrum. After the rotating frame 304 rotates counterclockwise, it drives the fixed rod 501 to make a circular motion with the rotating shaft 303 as the center. After the fixed rod 501 rotates a certain angle, the pressing plate 502 presses the pressing rod 702 and the spring 703 contracts. Further, the pressing rod 702 presses the sponge pad 705, and the lubricating oil inside the sponge pad 705 is squeezed out and flows from the diversion hole 706 between the rotating shaft 303 and the rotating frame 304 to lubricate the two, reduce wear, improve the protection effect on the corrugated pipe 202, and avoid abnormal noise. After the rotating frame 304 is reset, the pressing rod 702 is reset and no more oil will be used for lubrication to avoid waste. It is only necessary to regularly add lubricating oil to the oil leakage pipe 601.
