Description

Technical Field

[0001] The present invention relates to the field of valve technology, and more particularly to a valve plate clamping device and a use method thereof. Background Art

[0002] Angular-turn pneumatic valves are commonly used valves in production sites, including angular-turn single-acting pneumatic valves and angular-turn double-acting pneumatic valves. When the signal or air source is cut off, the valve will automatically turn to the fully open or fully closed state. Due to the production process, the valve body cannot be replaced during the use of the angular-turn pneumatic valve. When the pneumatic actuator or regulator of the valve body has problems and needs to be repaired or replaced, due to the characteristics of the angular-turn pneumatic valve, production can only be suspended for repair or replacement, which has a great impact on the production rhythm. Therefore, it is necessary to propose an auxiliary device to solve the above problems. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a valve plate clamping device and a method of use, which is locked and fixed to the rotating shaft of the angular stroke pneumatic valve so that the position of the valve plate in the pipeline remains unchanged, making it easy to handle problems of the pneumatic actuator components at will, effectively improving maintenance efficiency, and not affecting the production rhythm.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A valve plate clamping device comprises a screw, a nut and two clamping members, wherein the clamping member is an L-shaped plate, comprising a base plate and a vertical plate perpendicular to each other, a locking groove is arranged on the side of the vertical plate away from the base plate along the height direction of the vertical plate, the vertical plates of the two clamping members are arranged opposite to each other, and the two locking grooves lock and fix the rotating shaft of the angular stroke pneumatic valve, the vertical plate is provided with a plurality of through holes along the height direction, the screw passes through the through holes at the same height position of the two vertical plates, the nut is located outside the side of the vertical plate facing the base plate, and is threadedly connected to the screw to lock the two clamping members.

[0006] In one of the embodiments, a rough wear-resistant layer is provided in the locking groove of the clamping member.

[0007] In one of the embodiments, the valve plate clamping device also includes a locking belt, connecting rings are arranged at both ends of the locking belt, a cylindrical connecting protrusion is arranged at the center of the top surface of the bottom plate of the clamping piece, the outer diameter of the connecting protrusion is smaller than the inner diameter of the connecting ring, the connecting ring at one end of the locking belt is inserted into the outside of the connecting protrusion, the locking belt is wrapped around the circumference of the pipeline, and the connecting ring of the other end of the locking belt is also inserted into the outside of the connecting protrusion to lock the clamping piece on the pipeline.

[0008] In one of the embodiments, an annular groove is provided on the circumferential side surface of the connecting protrusion, and the connecting rings at both ends of the locking belt are inserted into the annular groove of the connecting protrusion.

[0009] In one embodiment, the valve plate clamping device also includes a detection component, which includes a proximity sensor and a detection piece. A mounting rod is set on the bottom plate of the clamping piece. The length of the mounting rod is greater than the height of the vertical plate. The proximity sensor is set at the top of the mounting rod. The detection piece is detachably set on the side of the rotating shaft, and the detection piece is at the same height as the proximity sensor, and the detection piece is close to the proximity sensor.

[0010] In one embodiment, the detection member is a magnetic member, which is fixed to the side of the rotating shaft by magnetic attraction.

[0011] A method for using a valve plate clamping device is as follows:

[0012] When it is necessary to disassemble or process the pneumatic actuator components of the angular stroke pneumatic valve, first adjust the opening of the angular stroke pneumatic valve to the position required for the current production, then place two clamping pieces on the pipeline, and the two clamping pieces are located on both sides of the rotating shaft of the angular stroke pneumatic valve, and pass multiple screws through the two clamping pieces respectively, and lock the two clamping pieces by connecting the nuts with the screws;

[0013] The two clamping pieces lock the rotating shaft. Since the two clamping pieces abut against the pipeline, the downward movement of the rotating shaft is restricted, so that the opening degree of the angular stroke pneumatic valve in the pipeline is determined;

[0014] The pneumatic actuator components of the angular stroke pneumatic valve are then replaced or repaired. After the replacement or repair is completed, the two clamping parts are loosened and disassembled, and the angular stroke pneumatic valve is put into use again.

[0016] When the shaft moves toward or away from the pipeline, the position of the detection part changes, and the proximity sensor no longer detects the detection part, sending a signal to the control system, which then sounds an alarm to remind on-site personnel to check the shaft position to prevent the shaft movement from causing changes in the opening in the pipeline and affecting production.

[0017] In summary, the present invention has the following beneficial effects:

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0026] like Figure 1-2 As shown, the present invention proposes a valve plate clamping device, including a screw 6, a nut 7 and two clamping members 1, wherein the clamping member 1 is an L-shaped plate, including a bottom plate 2 and a vertical plate 3 perpendicular to each other, and a locking through groove 4 is arranged on the side of the vertical plate 3 away from the bottom plate 2 along the height direction of the vertical plate 3, the vertical plates 3 of the two clamping members 1 are arranged opposite to each other, and the two locking through grooves 4 lock and fix the rotating shaft 13 of the angular stroke pneumatic valve, the vertical plate 3 is provided with a plurality of through holes 5 along the height direction, the screw 6 passes through the through holes 5 at the same height position of the two vertical plates 3, the nut 7 is located outside the side of the vertical plate 3 facing the bottom plate 2, and is threadedly connected to the screw 6 to lock the two clamping members 1.

[0027] In the present invention, the locking groove 4 is used to lock the rotating shaft 13. It is easy to understand that the minimum distance between the two locking holes 5 is smaller than the diameter of the rotating shaft 13. When the two clamping members 1 approach each other to the extreme position, the rotating shaft 13 is clamped, so that the relative position of the valve plate clamping device and the rotating shaft 13 is locked.

[0028] Based on the specific structure of the valve plate clamping device described above, the present invention also proposes a method for using the valve plate clamping device, which is as follows:

[0029] When it is necessary to disassemble or process the pneumatic actuator components of the angular stroke pneumatic valve, first adjust the opening of the angular stroke pneumatic valve to the position required for the current production, then place two clamping pieces 1 on the pipe 14, and the two clamping pieces 1 are on both sides of the rotating shaft 13 of the angular stroke pneumatic valve, and pass multiple screws 6 through the two clamping pieces 1 respectively, and connect the two clamping pieces 1 with the screws 6 through nuts 7 to lock the two clamping pieces 1;

[0030] The two clamping members 1 lock the rotating shaft 13. Since the two clamping members 1 abut against the pipe 14, the downward movement of the rotating shaft 13 is restricted, so that the opening degree of the angular stroke pneumatic valve in the pipe 14 is determined;

[0031] The pneumatic actuator components of the angular stroke pneumatic valve are then replaced or repaired. After the replacement or repair is completed, the two clamping parts 1 are loosened and disassembled, and the angular stroke pneumatic valve is put into use again.

[0032] Furthermore, in order to increase the friction between the clamping member 1 and the rotating shaft 13, a rough wear-resistant layer is provided in the locking groove 4 of the clamping member 1. When the two clamping members 1 are locked with the rotating shaft 13, the wear-resistant layers of the two clamping members 1 increase the friction and prevent the rotating shaft 13 and the clamping member 1 from sliding.

[0033] Further, such as Figure 3-4 As shown, in order to prevent the clamping member 1 from moving relative to the pipe 14, the valve plate clamping device further includes a locking belt 8, connecting rings 9 are arranged at both ends of the locking belt 8, a cylindrical connecting protrusion 10 is arranged at the center of the top surface of the bottom plate 2 of the clamping member 1, the outer diameter of the connecting protrusion 10 is smaller than the inner diameter of the connecting ring 9, the connecting ring 9 at one end of the locking belt 8 is inserted into the outside of the connecting protrusion 10, the locking belt 8 is wrapped around the circumference of the pipe 14, and the connecting ring 9 of the other section of the locking belt 8 is also inserted into the outside of the connecting protrusion 10, so as to lock the clamping member 1 on the pipe 14. It is easy to understand that the locking belt 8 has the ability to stretch a certain length. When the locking belt 8 is locked around the pipe 14, the locking belt 8 is in a tightened state, so that the clamping member 1 is in close contact with the pipe 14.

[0034] When a locking belt 8 is provided, the present invention can also be applied to the situation where the rotating shaft 13 escapes from the pipe 14 under unrestricted conditions. Specifically, after the two clamping members 1 lock the rotating shaft 13, the two locking belts 8 respectively lock the two clamping members 1 on the pipe 14. When the rotating shaft 13 tends to move into the pipe 14, the two clamping members 1 restrict the movement of the rotating shaft 13 in the box. When the rotating shaft 13 tends to move out of the pipe 14, the two clamping members 1 restrict the outward movement of the rotating shaft 13 under the action of the locking belts 8.

[0035] Furthermore, an annular groove is provided on the circumferential side of the connecting protrusion 10 , and the connecting rings 9 at both ends of the locking belt 8 are inserted into the annular grooves of the connecting protrusion 10 , which effectively prevents the connecting rings 9 from escaping from the connecting protrusion 10 .

[0036] Further, such as Figure 3-4 As shown, the valve plate clamping device also includes a detection component, which includes a proximity sensor 12 and a detection member 15. The bottom plate 2 of the clamping member 1 is provided with a mounting rod 11, the length of the mounting rod 11 is greater than the height of the vertical plate 3, the proximity sensor 12 is provided at the top of the mounting rod 11, the detection member 15 is detachably provided on the side of the rotating shaft 13, and the detection member 15 is at the same height as the proximity sensor 12, and the detection member 15 is close to the proximity sensor 12. It is easy to understand that the proximity sensor 12 is connected to the control system, and the control system is also connected to components such as an alarm.

[0037] In the case of setting the detection component, the method of using the present invention also includes the following contents:

[0038] After the two clamping members 1 lock the rotating shaft 13, the proximity sensor 12 is installed, and the detection member 15 is installed on the side of the rotating shaft 13, so that the proximity sensor 12 and the detection member 15 are at the same height, and the detection member 15 is close to the proximity sensor 12;

[0039] When the rotating shaft 13 moves toward the pipeline 14 or moves away from the pipeline 14, the position of the detection member 15 changes, and the proximity sensor 12 no longer detects the detection member 15, sends a signal to the control system, and then issues an alarm to remind on-site personnel to check the position of the rotating shaft 13 to prevent the movement of the rotating shaft 13 from causing changes in the opening in the pipeline 14 and affecting production.

[0040] Furthermore, the detection member 15 is a magnetic member, and is fixed to the side of the rotating shaft 13 by magnetic attraction.

[0041] The present invention is locked and fixed with the rotating shaft 13 of the angular stroke pneumatic valve, and the relative position between the rotating shaft 13 and the pipeline 14 is kept fixed, so that the position of the valve plate in the pipeline 14 remains unchanged, which is convenient for disengaging the fasteners connected to the pneumatic actuator part, and the problems of the pneumatic actuator parts can be handled arbitrarily, effectively improving the maintenance efficiency, and will not affect the production rhythm.

[0042] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
