Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pneumatic actuator spare parts, specifically to a detachable pneumatic actuator spare part. BACKGROUND

[0002] The rapid development of industrial automation has driven the demand for pneumatic actuators and their spare parts. Manufacturing, chemical, power and other industries have higher requirements for the availability and reliability of equipment. The detachable design makes the replacement and maintenance of spare parts more flexible, reduces the downtime of equipment, improves production efficiency, and the application of new wear-resistant and high-strength materials improves the durability and service life of spare parts. Combined with Internet of Things technology, the pneumatic actuator can be equipped with sensors to realize real-time monitoring and early detection of potential faults through data analysis to optimize the use and management of spare parts. The standardized design of spare parts makes interchangeability stronger, reduces inventory costs, and speeds up maintenance and replacement. The design of traditional control valves often has limitations in fixing and connecting, which requires a lot of time and effort to disassemble and maintain. This inefficient maintenance process not only affects the replacement efficiency of the control valve, but also brings many inconveniences to the later maintenance of the control valve. Frequent maintenance and replacement are often necessary. The complexity of traditional design makes the process more tedious, which may cause production to stop and result in economic losses. In addition, when the control valve is transporting the flowing medium, leakage often occurs due to insufficient sealing performance, which not only brings potential safety hazards, but also may cause serious environmental pollution and personal injury. In addition, fluid leakage may also cause a significant decrease in medium flow efficiency, which will directly affect the stability and economy of the production process. With the leakage of fluid medium, the internal pressure of the system may be unstable, affecting the smooth operation of the overall process, thereby further reducing production efficiency. Therefore, we propose a detachable pneumatic actuator spare part. SUMMARY

[0012] (Three) beneficial effects

[0013] Compared with the prior art, the utility model provides a kind of detachable pneumatic actuator spare parts, with following beneficial effects:

[0014] 1. The detachable pneumatic actuator spare part, by introducing two front and rear fixing mechanisms in the design, can significantly improve the efficiency and convenience of the connection of the control valve and other spare parts. This design optimization makes the control valve installation and disassembly process simpler, reduces the dependence on professional tools, greatly improves the work efficiency of maintenance personnel, and the two fixing mechanisms provide more stable support during connection, so that the valve can be accurately aligned during assembly, avoiding poor connection or sealing due to errors.

DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A detachable pneumatic actuator spare part includes a valve body structure, a front fixing mechanism, and a rear fixing mechanism. One end of the valve body structure is movably connected to the front fixing mechanism, and the other end of the valve body structure is movably connected to the rear fixing mechanism.

[0023] Furthermore, the valve body structure includes a valve body 1, a spring 10, a circular hole 14, and a rubber ring 15. The valve body 1 is formed by coaxially welding two cylindrical blocks of different diameters, and a through hole is opened on the plane of the valve body 1, penetrating to the other side. A circular hole 14 in a circumferential array is opened on the surface of the smaller diameter cylinder of the valve body 1. A spring 10 is fixedly installed behind the circular hole 14 on the surface of the smaller diameter cylinder of the valve body 1. A rubber ring 15 is coaxially fixedly connected inside the larger diameter cylinder of the valve body 1. Due to its good elasticity and corrosion resistance, the rubber ring 15 can adapt to various working environments and resist fluid erosion and temperature changes.

[0024] Furthermore, the front fixing mechanism includes a stabilizing block 2, a roller 3, and a retaining ring strip 16. The roller 3 is movably connected to the circular hole 14. The stabilizing block 2 is fitted onto the cylinder with a smaller diameter of the valve body 1. The arc surface of the stabilizing block 2 is provided with rectangular protrusions arranged in a circumferential array. The retaining ring strip 16 is fixedly installed on the inner wall of the stabilizing block 2. The setting of the fixing mechanism makes the installation and disassembly of the control valve simpler, reduces the reliance on professional tools, and greatly improves the work efficiency of maintenance personnel.

[0025] Furthermore, the rear fixing mechanism includes a fixing platform 4, a sliding bar 5, and a handle 13. The fixing platform 4 is fixedly connected to the outer arc surface of the valve body 1. A rectangular opening is provided on the fixing platform 4. The sliding bar 5 is inserted into the fixing platform 4 through the opening. A handle 13 is also fixedly provided at the end of the sliding bar 5, and a slot is provided at the other end of the sliding bar 5.

[0026] Furthermore, the rear fixing mechanism includes a second fixing platform 6, a connecting block 8, and a rubber ring 9. The rubber ring 9 is fixedly connected to the inner wall of the connecting block 8. The rubber ring 9 significantly improves the sealing effect of the control valve, effectively reduces the risk of medium leakage, ensures the stable flow of the medium inside the control valve, optimizes the fluid transmission process, and also provides a guarantee for the safety of the entire system. The second fixing platform 6 is fixedly installed on the outer wall of the connecting block 8. The second fixing platform 6 has a slot on the side near the sliding bar 5, and the shape and size of the slot are consistent with the shape and size of the slot of the sliding bar 5. The sliding bar 5 is inserted into the second fixing platform 6 through the slot. Two parallel rectangular grooves are also opened on the side of the second fixing platform 6.

[0027] Furthermore, the rear fixing mechanism also includes a fixing block 7 and a second spring 12. The fixing block 7 is slidably connected to the second fixing platform 6 through two parallel rectangular grooves on the second fixing platform 6. The second spring 12 is fixedly installed on the inner wall of the fixing block 7, and the other end of the second spring 12 is fixedly connected to the inner wall of the second fixing platform 6. Moreover, the shape and size of the end of the fixing block 7 near the sliding strip 5 are consistent with the shape and size of the groove of the sliding strip 5. The fixing mechanism provides more stable support during the connection process, so that the valve can be accurately aligned during assembly, avoiding poor connection or poor sealing due to errors. In addition, this double fixing structure makes it easier to loosen the various connecting parts during disassembly, preventing the problem of difficult disassembly caused by tightness in traditional structures.

[0028] Working principle: To replace the front part of valve body 1, first, grasp roller 3 and push it backward. Simultaneously, apply a backward force to spring 10. This causes spring 10 to compress, thus relieving roller 3 of the compressive force of retaining ring 16. As roller 3 disengages from the compression of retaining ring 16, it begins to move upward. At this point, the connecting body can detach from valve body 1. After replacing it with a new connecting body, release the stabilizing block 2. Spring 10 will return to its original state. Push the stabilizing block 2 forward. At this time, retaining ring 16 will press down on roller 3, causing roller 3 to move upward... The valve moves downward and contacts the groove on the new connector, thus locking the new connector. To install the rear of the valve body 1, first pull the fixing block 7, and the sliding bar 5 inserts the slot at the front end of the sliding bar 5 into the slot of the fixing platform 2 6. Release the fixing block 7, and use the spring 2 12 to push the fixing block 7, which will then push the fixing block 7 into the slot on the sliding bar 5, thus installing the control valve. When the control valve needs to be disassembled for maintenance and replacement, pull the fixing block 7 to disengage it from the slot on the sliding bar 5, and then pull the handle 13 to disengage the sliding bar 5 from the slot, thus completing the disassembly of the high-pressure valve.
