Description

Technical Field

[0001] The invention relates to the technical field of safety valve calibration, in particular to a safety valve calibration and marking integrated calibration platform. Background Art

[0002] Safety valves are extremely important safety pressure relief devices on boilers, pressure vessels and pressure pipes. They play an automatic pressure relief protection role when the pressure equipment or system is over-pressured. The quality and performance of their products directly affect the safe operation of the pressure equipment. In order to ensure the quality and safety of safety valves, the national safety technical specification "Safety Technical Supervision Regulations for Safety Valves" stipulates that safety valves must be calibrated once a year, and the contents of the calibration include: set pressure and sealing performance.

[0003] When checking the safety valve, since some safety valves have flanges, the flanges need to be tightened with multiple bolts to ensure that they are firmly fixed and sealed. However, this method requires that all bolts be tightened firmly to meet the safety valve verification requirements, and all bolts must be removed to remove the safety valve after the verification, which makes the inspection operation very inconvenient. At the same time, when clamping safety valves of different calibers, due to the inability to adjust well, the safety valve is likely to shake during the verification process, affecting the verification results. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a safety valve calibration and marking integrated calibration platform, including a platform, and an air pump fixedly installed at the bottom of the platform;

[0006] A marking mechanism, wherein the marking mechanism is fixedly mounted on the top of the platform;

[0007] A control box, the control box is fixedly connected to the top of the platform, and the control box is connected to the fixing mechanism, the marking mechanism and the air pump line;

[0008] The cam is provided with a plurality of grooves, and the grooves are provided at the inner wall of the grooves, and the grooves are connected with the inner wall of the grooves in a sliding manner. The grooves are provided with a plurality of grooves, and the grooves are connected with the plurality of grooves in a plurality of directions. One end of the fixed ring is fixedly connected with a return spring, and the return spring is provided to ensure that the limit plate can always be close to the safety valve and does not damage the safety valve. At the same time, the return spring also plays a returning role, and the one end of the return spring away from the limit plate is fixedly connected to the support plate, and the return spring is located inside the slide groove, and the outer wall of the limit plate is slidably connected to the fixed frame, and the bottom of the fixed frame is fixedly connected with a spring plate, and the end of the fixed frame near the square hole is provided with a sealing block. During operation, when a safety valve with a larger diameter is clamped, under the elastic force of the spring plate, the sealing block at one end of the fixed frame is located inside the square hole, so that the safety valve and the circular plate form a closed space to avoid gas leakage through the square hole during the verification process, resulting in inaccurate verification results. When a safety valve with a smaller diameter is clamped, the limit plate drives the fixed frame to slide inside the circular plate, so that the limit plate clamps the outer wall of the safety valve, and the end of the spring plate away from the fixed frame is fixedly connected to the limit plate, and the inner wall of the support plate is slidably connected with a ventilation component, and the ventilation component passes through the support plate.

[0009] Preferably, the ventilation assembly includes a circular plate, the bottom of which is fixedly connected to a circular tube, the circular tube passes through a supporting plate, and one end of the circular plate close to the circular tube is fixedly connected to a compression spring. During operation, the horizontal bottom of the safety valve is placed on the circular plate, and the circular plate is subjected to force to drive the circular tube to move in the direction of the connecting tube, so that the compression spring is compressed. The elastic properties of the compression spring are utilized, and at the same time, extension plates at both ends of the limit plate are used to clamp and cooperate with the extension plates and the circular plate to fix the flange of the safety valve, thereby improving the fixity of the equipment and preventing the safety valve from detaching from the equipment during verification, resulting in inaccurate verification results. One end of the compression spring away from the circular plate is fixedly connected to the supporting plate, and a square hole is provided on the top of the circular plate. A sleeve is slidably connected to the inner wall of the circular tube, and one end of the sleeve away from the circular plate The end is fixedly connected with a magnetic ring, and the magnetism between the magnetic ring and the magnetic plate is the same. When working, the circular plate is forced to move in the direction of the connecting pipe. Under the action of the mutual repulsion between the magnetic ring and the magnetic plate, the sleeve maintains the current position, and then the sleeve exceeds the circular plate, so that the sleeve contacts the inner wall of the safety valve, thereby improving the air tightness during the verification process and improving the accuracy of the verification data. At the same time, the circular tube slides on the limiting tube, and the limiting tube connects the circular tube and the connecting tube. By setting a sealing ring, the air tightness between the connecting tube and the circular tube during the working process is good. The end of the circular tube away from the circular plate is slidably connected to the limiting tube, and the end of the limiting tube close to the sleeve is fixedly connected with a magnetic plate, and the end of the limiting tube away from the magnetic plate is fixedly connected with a sealing ring. The inner wall of the limiting tube is fixedly connected with a connecting tube, and the connecting tube is fixedly connected to the output pipe of the air pump.

[0010] Preferably, the platform includes a bottom plate, the bottom of the bottom plate is fixedly connected to a support rod, the top of the bottom plate is provided with a through groove, the inner wall of the through groove is slidably connected to a moving plate, the top of the moving plate is slidably connected to a supporting plate, the outer wall of the supporting plate is set to an arc shape, the channel on the side of the safety valve is placed on the moving plate, and during the process of placing the safety valve downward, it contacts and squeezes the outer wall of the supporting plate, so that the limit spring is forced to shrink, and then the inner wall of the through hole on the side of the safety valve is pressed through multiple supporting plates. After being fixed, the moving plate is pushed to slide toward the supporting plate in the through groove, so that the bottom of the safety valve contacts the circular plate. By arranging the moving plate and the through groove, a guiding and positioning effect is played when fixing the safety valve, the outer wall of the support plate is fixedly connected to the limit spring, and one end of the limit spring away from the support plate is fixedly connected to the moving plate, the outer wall of the bottom plate is fixedly connected to a motor, and the output end of the motor is fixedly connected to a screw, the top of the bottom plate is provided with a moving groove, the screw is located inside the moving groove, the through groove is close to one end of the fixing mechanism, and the moving groove is located at one end of the control box.

[0011] Preferably, the marking mechanism includes a support rod, which is threadedly connected to the outer wall of the screw rod, the support rod is located in the moving groove, the support rod is slidably connected to the moving groove, and the top of the support rod is fixedly connected to a positioning plate. During the working process, after the verification is completed, the verification data result is fed back to the inside of the control box, and the staff passes the verification data through the control box through the marking mechanism to engrave the data on the safety valve. The motor is connected to an external power supply to work, and the motor drives the screw rod to move horizontally, and then the screw drives the support rod to move horizontally. At the same time, the positioning plate moves vertically on the support rod, so that the positioning plate drives the positioning rod to contact the top of the safety valve, thereby positioning. The positioning plate is fixedly connected to one end away from the support rod, and the positioning ring is set as an L-shaped plate, and the bottom of the positioning rod is set as an arc. During operation, the bottom of the positioning rod fits the outer wall of the safety valve. Under the specified wavelength laser, the positioning plate is prevented from moving downward excessively, and the laser marking depth is prevented from being too deep. The bottom of the positioning plate is fixedly connected to a laser emitter, and the bottom of the positioning ring is fixedly connected to a positioning rod. The positioning rods are evenly distributed with the laser emitter as the center, and the outer wall of the positioning ring is fixedly connected to a cleaning mechanism.

[0012] Preferably, the cleaning mechanism includes a connecting rod, the bottom of the connecting rod is fixedly connected to a round rod, the outer wall of the round rod is rotatably connected to a rotating rod, the outer wall of the rotating rod is fixedly connected to an elastic plate, the end of the elastic plate away from the rotating rod is fixedly connected to the round rod, and the end of the rotating rod away from the round rod is fixedly connected to a cleaning plate. During operation, the positioning plate moves downward and the cleaning plate contacts the surface of the safety valve. As the positioning plate continues to move downward, under the elastic force of the elastic plate, the cleaning plate moves along the outer wall of the safety valve, and then cleans the area to be marked to avoid stains at the marking area, thereby hindering the precise focusing and energy transfer of the laser, resulting in the marking pattern or text not being clear enough, making the marking quality deteriorate, and may appear blurred, incomplete or irregular. A ball is fixedly connected to the end of the round rod away from the connecting rod.

[0013] The present invention provides a safety valve inspection and marking integrated inspection platform, which has the following beneficial effects:

[0014] 1. The integrated inspection table for checking and marking the safety valve is provided with extension plates at both ends of the limit plate, and the extension directions of the extension plates are opposite. The bottom extension plate extends toward the direction of the fixed ring. The arc-shaped protrusions on the inner wall of the fixed ring contact and squeeze the limit plate, so that the limit plate moves toward the circular plate inside the slide groove, so that the limit plate clamps and fixes the outer wall of the safety valve. By adjusting the position of the limit plate on the supporting plate, safety valves of different calibers can be clamped, thereby improving the applicability of the equipment.

[0015] 2. When the integrated inspection table for safety valve inspection and marking is used to clamp a safety valve with a larger diameter, the sealing block at one end of the fixed frame is located inside the square hole under the elastic force of the spring plate, so that the safety valve and the circular plate form a closed space to avoid gas leakage through the square hole during the inspection process, resulting in inaccurate inspection results. When the safety valve with a smaller diameter is clamped, the limit plate drives the fixed frame to slide inside the circular plate, so that the limit plate clamps the outer wall of the safety valve.

[0016] 3. The integrated inspection table for safety valve inspection and marking uses the extension plates at both ends of the limit plate to clamp and cooperate with the circular plate to fix the flange of the safety valve, thereby improving the fixity of the equipment and preventing the safety valve from detaching from the equipment during the inspection process, resulting in inaccurate inspection results.

[0017] Fourth, the integrated inspection and marking inspection table for the safety valve uses multiple support plates to inspect the inner wall of the side through hole of the safety valve. After fixing it, the movable plate is pushed to slide toward the support plate in the through groove, so that the bottom of the safety valve contacts the circular plate. By setting the movable plate and the through groove, it plays a guiding and positioning role when fixing the safety valve.

[0018] 5. The integrated verification table for safety valve verification and marking is set as an L-shaped plate through a positioning ring, and the bottom of the positioning rod is set as an arc. When working, the bottom of the positioning rod fits with the outer wall of the safety valve. Under the specified wavelength laser, the positioning plate is prevented from moving downward excessively, preventing the laser marking depth from being too deep.

[0019] 6. The integrated verification table for safety valve verification and marking contacts the surface of the safety valve through the cleaning plate. As the positioning plate continues to move downward, the cleaning plate moves along the outer wall of the safety valve under the elastic force of the elastic plate, and then cleans the area to be marked to avoid stains at the marking area, thereby hindering the precise focusing and energy transfer of the laser, resulting in unclear marking patterns or texts, poor marking quality, and possible blurring, incompleteness or irregularity.
