Description

Technical Field

[0001] The invention relates to the technical field of valve core cleaning, and in particular to a valve hole cleaning device for an automatic valve. Background Art

[0002] Automatic valves are valves that do not require external force to drive, but rely on the energy of the medium itself to make the valve move. Such as safety valves, pressure reducing valves, steam traps, check valves, automatic regulating valves, etc. During the long-term use of automatic valves, they may be affected by internal foreign matter accumulation or crystallization, causing blockage, such as sediment, iron filings, process raw materials and other foreign matter; or due to defects in the design of automatic valves, dead corners or eddy currents may appear inside the pipeline, leading to the accumulation of sediments and causing pipeline blockage. Therefore, during the long-term use of automatic valves, regular cleaning and maintenance are required.

[0003] During the cleaning process of the valve hole of the automatic valve, due to the complexity of the automatic valve structure and the limited internal space of the valve hole, it is difficult for existing cleaning tools to effectively clean the dead corners that can be reached, resulting in unsatisfactory cleaning effects and affecting the normal operation of the subsequent automatic valve. At the same time, although overly strong cleaning methods or cleaning agents can ensure the cleaning effect, they may damage the surface quality of the valve hole and affect the sealing and service life of the automatic valve. Therefore, the present invention provides a valve hole cleaning device that can be adjusted according to the situation of the valve hole itself, thereby reducing damage to the valve hole while ensuring the cleaning effect. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a valve hole cleaning device for an automatic valve, which is used to perform bending adjustment according to the specific conditions of the valve hole, thereby reducing contact damage to the valve hole and ensuring the cleaning effect.

[0005] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: a valve hole cleaning device for an automatic valve, comprising a bracket, on which a fixing mechanism for mounting a valve body is provided;

[0006] A liquid spraying mechanism is provided on one side of the fixing mechanism, and the liquid spraying mechanism includes a driving member, the driving member is slidably matched with the bracket, and the output shaft of the driving member is coaxially fixedly connected with a mounting rod; a rotating rod for adjusting the cleaning angle is provided at one end of the mounting rod close to the fixing mechanism, and a ball is hinged at one end of the rotating rod away from the mounting rod, and an ultrasonic generator for generating ultrasonic waves is provided in the ball;

[0007] A plurality of nozzles for spraying cleaning liquid are also arranged on one side of the rotating rod away from the rotating direction of the driving member.

[0008] The technical principles of the above scheme are as follows:

[0009] The fixing mechanism drives the valve body to rotate, so that the tortuous valve hole and the liquid ejection mechanism are kept in the center position, so that the ball on the mounting rod forms an annular rotating surface for contact cleaning during the contact process with the valve hole. The driving member then drives the mounting rod to rotate, so that the ultrasonic generator vibrates the bubbles generated on the annular water surface to generate cavitation to clean the valve hole and remove impurities inside the valve body.

[0010] The above scheme has the following beneficial effects:

[0011] 1. In this scheme, contact cleaning is performed by rotating the mounting rod to form several annular surfaces to clean the valve holes one by one, so as to achieve comprehensive cleaning of the valve holes and reduce impurity residues in the valve holes due to inadequate cleaning.

[0012] 2. Compared with the prior art, this solution adopts a steel ball contact method to reduce friction and alleviate surface damage to the valve hole during the cleaning process.

[0013] 3. This solution utilizes the cleaning fluid sprayed from the nozzle to drive the mounting rod to rotate, thereby increasing the contact area between the cleaning fluid and the air to generate a number of bubbles in the cleaning fluid. At the same time, the rotation speed of the rotating rod is accelerated, so that the ultrasonic generator vibrates and ruptures the bubbles in the cleaning fluid, so that the closed shock waves of the bubbles expand and clean the surface of the valve hole, making it easier for the bubbles in the cleaning fluid to clean the tortuosity, thereby achieving comprehensive cleaning of the inside of the valve hole.

[0014] Furthermore, the fixing mechanism comprises an annular disk, on which a plurality of bolt holes arranged in an annular shape are formed; and a side of the annular disk away from the liquid ejection mechanism is hinged to the bracket.

[0015] Beneficial effects: A number of bolt holes arranged in an annular shape are used to meet the installation requirements of automatic valves of different sizes, so as to maintain stability during the cleaning process of the valve hole; and the annular disk is hinged with the bracket so that the curved valve body can be rotated to remain level with the installation hole, so as to facilitate subsequent cleaning.

[0016] Furthermore, the liquid spraying mechanism also includes a mounting plate, a slide groove is opened in the center of the mounting plate, and extension blocks are fixedly connected on both sides of the driving member, the extension blocks are located in the slide groove, and the extension blocks and the slide groove are gap-matched; a ring is fixedly connected to one side of the mounting plate close to the fixing mechanism, and the ring is slidingly matched with the mounting rod.

[0017] Beneficial effect: The extension block and the collar are used to limit and support the mounting rod to ensure stability during use.

[0018] Furthermore, a plurality of threads are formed on the mounting rod, and screw teeth are provided on one side of the mounting rod; an adjusting rod is fixedly connected to the center of the screw teeth, one end of the adjusting rod away from the screw teeth extends outside the mounting plate, and a handle is fixedly connected to the other end of the adjusting rod away from the screw teeth.

[0019] Beneficial effect: The screw teeth are engaged with the threads, and the mounting rod is pushed forward to automatically and continuously clean the stable surface in the valve body during the continuous rotation of the mounting rod. At the same time, the screw teeth are driven to rotate by the handle to achieve the purpose of controlling the engagement of the screw teeth with the threads on the mounting rod, so as to control whether the mounting rod moves in a straight line.

[0020] Further, the rotating rod comprises a rotating block, a first rod, a second rod and a third rod which are arranged in sequence from right to left, and the rotating block is threadedly connected to the mounting rod;

[0021] A first groove is formed on the rotating block, and both ends of the first rod are fixedly connected with a vertically arranged clamping shaft; a second groove and a third groove for the clamping shaft to rotate are formed at both ends of the second rod, and the third groove is located on both sides of the second groove; one end of the third rod is hinged with a ball bearing, and the other end of the third rod is fixedly connected with the clamping shaft;

[0022] The two ends of the first rod are respectively rotatably matched with the rotating block and the second rod through a clamping shaft, and the end of the third rod away from the ball is rotatably matched with the second rod through a clamping shaft;

[0023] A clamping mechanism for rotating and fixing the rotating rod is provided between adjacent rotating blocks and the first rod, between the first rod and the second rod, and between the second rod and the third rod; the clamping mechanism includes an electromagnet located at the center of the rotating shaft, the electromagnet is electrically connected to a control panel for manually controlling the working condition of the electromagnet, a plurality of limit rods are arranged circumferentially of the electromagnet, the included angles of adjacent limit rods are the same, and the limit rods are slidably matched with the clamping shaft, and a second spring support is provided between the clamping shaft and the electromagnet; a limit groove corresponding to the limit rod is provided on the second rod and the rotating block;

[0024] When the limit rod is in a normal state, the limit rod is located in the limit groove; when the limit rod is adsorbed by the electromagnet, the limit rod is located in the clamping shaft.

[0025] Beneficial effects: The working condition of the electromagnet is controlled through the control panel to realize the control of the extension and retraction of the limit rod, so as to control the adjacent rotating rod to adjust to any angle to contact the valve hole, so as to be suitable for cleaning of valve bodies of different shapes; the limit rod is engaged with different limit grooves to realize the fixing of the rotating rod at any angle to meet the stability during the cleaning process.

[0026] Furthermore, a first spring is provided at one end of the third rod close to the ball, and the first spring is located between the steel ball and the third rod.

[0027] Beneficial effect: The first spring support is used to ensure that the steel ball can fit and clean the slight gap changes during the valve hole cleaning process, ensuring that the liquid ejection mechanism can clean the valve hole.

[0028] Furthermore, the control panel is electrically connected to the driving member, a pressure sensor is fixedly connected inside the third rod, the pressure sensor is located on a side of the spring away from the ball, and the pressure sensor is used to record the real-time pressure value of the spring on the pressure sensor and send the real-time pressure value to the control panel;

[0029] The control panel is used to record the number of changes in the current interval based on the change range of the peak and valley values ​​of the real-time pressure value, and compare the number of changes in the current interval with the set standard number. If the number of changes is greater than the standard number, a speed reduction instruction is sent to the drive component. If the number of changes is less than the standard number, a normal speed instruction is sent to the drive component.

[0030] Beneficial effect: By adjusting the rotation speed, the speed of the steel ball is reduced when it encounters the valve hole surface with a lot of impurities attached. After the speed is reduced, an ultrasonic generator is used to pre-clean the surface impurities to improve the flatness of the valve hole surface and ensure the stability of the subsequent steel ball during the cleaning process, thereby reducing the damage to the valve hole caused by the attached impurities during the cleaning process.

[0031] Furthermore, an indicator light is fixedly connected to the mounting plate and electrically connected to the control panel. The control panel is also used to compare the real-time pressure value with the set rated value. If the real-time pressure value is greater than the rated value, a start command is sent to the indicator light; if the real-time pressure value is less than the rated value, a continuous monitoring command is sent to the pressure sensor.

[0032] Beneficial effect: The indicator light is used to remind you to judge the fit between the ball and the inside of the valve body, avoiding scratches on the valve hole caused by excessive fit. Under the premise of ensuring fit cleaning, the damage to the valve hole caused by attached impurities during the cleaning process is reduced.

[0033] Furthermore, the fixing mechanism further comprises a slider and a slide rod, both ends of the slide rod are fixedly connected to the bracket, and the slider and the slide rod are slidably matched, and the arrangement directions of the slide rod and the annular disk are perpendicular to each other;

[0053] The following is further described in detail through specific implementation methods:

[0054] Embodiment 1:

[0055] As attached Figures 1 to 10Shown: A valve hole cleaning device for an automatic valve, comprising a bracket 1, on which a fixing mechanism for mounting a valve body 3 is provided; the fixing mechanism comprises an annular disk 2, on which a plurality of bolt holes arranged in an annular shape are opened (not shown in the figure); and the annular disk 2 is hinged to the bracket 1 at a side away from the liquid ejection mechanism.

[0056] A liquid ejection mechanism is provided on one side of the fixing mechanism, and the liquid ejection mechanism includes a driving member and a mounting plate 4. The driving member is a motor 51, and a slide groove is provided at the center of the mounting plate 4. Extension blocks 52 are welded on both sides of the driving member, and the extension blocks 52 are located in the slide groove, and the extension blocks 52 are in clearance with the slide groove; a collar (not shown in the figure) is integrally formed on one side of the mounting plate 4 close to the fixing mechanism, and the collar is in sliding cooperation with the mounting rod 5. The output shaft of the driving member is coaxially clamped with the mounting rod 5. The mounting rod 5 is provided with a plurality of threads, and a screw tooth 6 is provided on one side of the mounting rod 5; an adjusting rod 61 is clamped at the center of the screw tooth 6, and the end of the adjusting rod 61 away from the screw tooth 6 extends to the outside of the mounting plate 4, and a handle (not shown in the figure) is welded on the end of the adjusting rod 61 away from the screw tooth 6.

[0057] The end of the mounting rod 5 close to the fixing mechanism is provided with a rotating rod 71 for adjusting the cleaning angle. The rotating rod 71 includes a rotating block 7, a first rod 73, a second rod 74 and a third rod 75 arranged from right to left in sequence. The rotating block 7 is threadedly connected to the mounting rod 5; the rotating block 7 is provided with a first groove, and both ends of the first rod 73 are welded with a vertically arranged clamping shaft 72; the two ends of the second rod 74 are provided with a second groove and a third groove for the clamping shaft 72 to rotate, and the third groove is located on both sides of the second groove; one end of the third rod 75 is hinged with a ball 8, and an ultrasonic generator for generating ultrasonic waves is arranged in the ball 8, and the other end of the third rod 75 is fixedly connected with the clamping shaft 72; the two ends of the first rod 73 are respectively rotatably matched with the rotating block 7 and the second rod 74 through the clamping shaft 72, and the end of the third rod 75 away from the ball 8 is rotatably matched with the second rod 74 through the clamping shaft 72. In addition, the end of the third rod 75 close to the ball 8 is also provided with a first spring 82, and the first spring 82 is located between the steel ball and the third rod 75.

[0058] A clamping mechanism for rotating and fixing the rotating rod 71 is provided between the adjacent rotating blocks 7 and the first rod 73, between the first rod 73 and the second rod 74, and between the second rod 74 and the third rod 75; the clamping mechanism includes an electromagnet 721 located at the center of the rotating shaft, the electromagnet 721 is electrically connected to a control panel (not shown in the figure) for manually controlling the working condition of the electromagnet 721, and a plurality of limiting rods 722 are arranged circumferentially of the electromagnet 721, the included angles of adjacent limiting rods 722 are the same, and the limiting rods 722 are slidably matched with the clamping shaft 72, and a second spring support is provided between the clamping shaft 72 and the electromagnet 721; a limiting groove 741 corresponding to the limiting rod 722 is provided on the second rod 74 and the rotating block 7; when the limiting rod 722 is in a normal state, the limiting rod 722 is located in the limiting groove 741, and when the limiting rod 722 is adsorbed by the electromagnet 721, the limiting rod 722 is located in the clamping shaft 72.

[0059] A plurality of nozzles 91 for spraying cleaning liquid are also provided on the side of the rotating rod 71 away from the rotation direction of the driving member. Water pipes 9 are provided at the centers of the first rod 73, the second rod 74 and the third rod 75, and the water pipes 9 are connected to the nozzles 91. A buffer layer is provided outside the water pipe 9. In this embodiment, the buffer layer is a thermoplastic resin, such as a polyolefin resin, a polyamide resin and a modified elastomer having a reactive group that reacts with the polyamide resin.

[0060] The specific implementation process is as follows: First, the valve body 3 to be cleaned is installed on the annular disk 2 by bolts. If the valve hole of the valve body 3 is a linear valve hole, the center of the valve hole is aligned with the installation hole, and the electromagnet 721 is started through the control panel to adjust the rotation angles of the first rod 73, the second rod 74 and the third rod 75 so that the ball 8 contacts the valve hole. Then, the electromagnet 721 releases the fixed adsorption of the limit rod 722, and the limit rod 722 is engaged with different limit grooves 741 by the push of the second spring, so as to realize the fixing of the rotating rod 71 at any angle to meet the stability during the cleaning process.

[0061] Then, by rotating the adjusting rod 61, the screw teeth 6 are meshed with the thread, and during the rotation of the installation rod 5, the meshing of the screw teeth 6 and the thread is used to push the installation rod 5 forward, so as to automatically push and continuously clean the stable surface in the valve body 3, thereby reducing manual pushing. When it is necessary to stop pushing, the adjusting rod 61 is manually rotated to separate the screw teeth 6 from the thread of the installation rod 5. Since the ball 8 and the valve hole are rotated for cleaning, when the ball 8 on the rotating rod 71 moves to the bend, the direct contact is converted into rotating contact, so as to reduce the impact damage to the valve hole during the cleaning process.

[0062] During the rotation of the mounting rod 5, the steel ball contact method is used to reduce the friction, so as to reduce the surface damage to the valve hole during the cleaning process. At the same time, the driving force of the nozzle 91 is used to assist in driving the mounting rod 5 to rotate to improve the energy efficiency. Since the cleaning liquid is filling the valve body 3 or the cleaning liquid has filled the inside of the valve body 3, the rotation of the mounting rod 5 will continue to stir the cleaning liquid, thereby accelerating the generation of bubbles. The mounting rod 5 drives the ball 8 to rotate, so that the ultrasonic generator vibrates and breaks the bubbles in the cleaning liquid, so that the shock wave closed after the bubble expands clears the surface of the valve hole, and the inside of the valve hole is fully cleaned.

[0063] If the valve hole of the valve body 3 is a zigzag valve hole, the annular disk 2 and the rotating rod 71 are rotated in a front-to-back order based on the direction of the zigzag valve hole, so that the mounting rod 5 is located at the center of the valve hole to be cleaned for annular cleaning. The mounting rod 5 is slowly pushed to move manually, and the adjacent rotating rods 71 ​​are controlled to adjust to any angle to contact the valve holes at different positions, so as to be suitable for cleaning valve holes of different shapes. If the mounting rod 5 cannot directly enter the inside of the valve hole that is similar to a right angle, the ball 8 is used at the intersection closest to the valve hole, and the motor 51 drives the mounting rod 5 to rotate continuously, so that the rotating rod 71 stirs the cleaning liquid, forms a certain driving force to make the cleaning liquid enter the valve hole, and uses ultrasonic cavitation to clean the inside of the valve hole that is similar to a right angle.

[0064] Embodiment 2:

[0065] The difference from Example 1 is that the control panel is electrically connected to the driving member, and the pressure sensor 81 is fixedly connected to the third rod 75 by bolts. The pressure sensor 81 is located on the side of the spring away from the ball 8. The pressure sensor 81 is used to record the real-time pressure value of the spring on the pressure sensor 81 and send the real-time pressure value to the control panel.

[0066] The control panel is used to record the number of changes in the current interval based on the change range of the peak and valley values ​​of the real-time pressure value, and compare the number of changes in the current interval with the set standard number. If the number of changes is greater than the standard number, a speed reduction instruction is sent to the drive component. If the number of changes is less than the standard number, a normal speed instruction is sent to the drive component.

[0067] For example, during the rotation of the rotating rod 71, the valve hole surface with many impurities attached has a large reaction force on the steel ball, which makes it easy for the ball 8 to push the impurities and cause friction damage to the valve hole surface. By adjusting the rotation speed to reduce the speed of the steel ball when it encounters the valve hole surface with many impurities attached, after the speed is reduced, the surface impurities are pre-cleaned using an ultrasonic generator to improve the flatness of the valve hole surface and ensure the stability of the subsequent steel ball during the cleaning process, thereby reducing the damage to the valve hole caused by the attached impurities during the cleaning process.

[0068] Embodiment 3:

[0069] The difference from Example 2 is that an indicator light (not shown in the figure) is carded on the mounting plate 4, and the indicator light is electrically connected to the control panel. The control panel is also used to compare the real-time pressure value with the set rated value. If the real-time pressure value is greater than the rated value, a start command is sent to the indicator light; if the real-time pressure value is less than the rated value, a continuous monitoring command is sent to the pressure sensor 81.

[0070] For example, when adjusting the rotation angle of the rotating rod 71, the staff cannot judge the contact status of the ball 8 and the valve hole due to the obstruction of the valve body 3. The indicator light is used as a reminder to facilitate the judgment of the fit between the ball 8 and the inside of the valve body 3, avoiding scratches on the valve hole caused by excessive fit. Under the premise of ensuring fit and cleaning, the damage to the valve hole caused by attached impurities during the cleaning process is reduced.

[0071] Embodiment 4:

[0072] The difference from the third embodiment is that the fixing mechanism further comprises a slider 21 and a slider 11, both ends of the slider 11 are fixedly connected to the bracket 1, and the slider 21 and the slider 11 are slidably matched, and the arrangement directions of the slider 11 and the annular disk 2 are perpendicular to each other;

[0073] The slider 21 and the annular disk 2 are in the same horizontal direction and are fixedly connected with a support rod, one end of the support rod is hinged to the annular disk 2, and the other end of the support rod is slidably matched with the bracket 1, and the support rod is fixedly connected to both ends of the slider 21.

[0074] The specific implementation process is as follows: the annular disk 2 is supported by the support rod and the slide rod 11 to ensure the stability of the annular disk 2 in the support, and then the slider 21 is moved on the slide rod 11 to push the valve body 3 on the annular disk 2 to move horizontally, so that the position of the center of the valve hole of the special-shaped valve hole can be adjusted after rotation, so that the center of the contacting valve hole surface is consistent with the mounting rod 5, which is convenient for subsequent cleaning.

[0075] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
