Description

Technical Field

[0001] The utility model relates to the field of gas pipelines, in particular to an anti-stamping gas pipeline. Background Technique

[0002] A pneumatic actuator is a device that converts pneumatic energy into mechanical motion. It can convert the output signal of the controller into the linear displacement of the control valve stem or the angular displacement of the valve shaft, providing driving force or torque to overcome unbalanced forces, valve pressing forces, and frictional forces, etc. Pneumatic actuators have the advantages of fast response speed, large torque, simple control, simple structure, easy maintenance, long service life, and high reliability, and are widely used in various mechanical equipment, such as automated production lines, machining processes, and robot motion control. According to its working mode, pneumatic actuators can be divided into two types: double-acting and single-acting, which achieve the switching action through full driving by the air source and spring reset respectively. When the air source is first introduced into the pneumatic actuator, due to the instantaneous increase in pressure in the pipeline, it is easy to cause damage to the relevant rubber materials of the pneumatic actuator due to the instantaneous increase in pressure, which will increase the use and maintenance costs of the pneumatic actuator, and at the same time, the reliability of the pneumatic actuator will be poor. Therefore, an anti-stamping gas pipeline is needed to solve the above problems. Content of the Utility Model

The lower component 3 is composed of a lower housing 8 and a fixing plate 11. The fixing plate 11 is fixedly installed on the outer wall of the lower housing 8. The upper component 4 is composed of an externally threaded upper housing 13, a substrate 15, a square rod 16, and an anti - detachment plate 17. The substrate 15 is fixedly installed on the outer wall of the externally threaded upper housing 13. The square rod 16 is fixedly installed at the lower end of the substrate 15. The square rod 16 is also movably inserted into the fixing plate 11. The anti - detachment plate 17 is fixedly installed at the lower end of the square rod 16. An adjusting component 5 is installed on the lower housing 8 and the externally threaded upper housing 13. A sealing component 6 is fixedly sleeved on the upper component 4. The sealing component 6 is also located at the upper end of the adjusting component 5. The sealing component 6 is composed of a fixing ring 20, a sealing spring 21, and a rubber sealing ring 22. The sealing spring 21 is fixedly installed at the lower end of the fixing ring 20. The rubber sealing ring 22 is fixedly installed at the lower end of the sealing spring 21. During use, the expander composed of the lower component 3 and the upper component 4 cooperates with the adjusting component 5, which can provide buffering for the air source entering the pneumatic actuator 7 through the first air pipe 1 and the second air pipe 2. Thus, it can avoid damage to the relevant sealing rubber materials of the pneumatic actuator 7 due to an instantaneous increase in pressure or unstable working conditions when the air source is initially input, or damage to the first air pipe 1 and the second air pipe 2 due to excessive surging inside. Ultimately, it effectively ensures the reliability of the pneumatic actuator 7 in use.

[0018] Further, an annular groove 9 is formed on the outer wall of the upper side of the lower housing 8, the fixing plate 11 is located below the annular groove 9, a first hole 10 is formed on the lower side wall of the lower housing 8, a square hole 12 is formed on the fixing plate 11, a second hole 14 is formed on the upper side wall of the externally threaded upper housing 13, the externally threaded upper housing 13 is located above the lower housing 8, a square rod 16 is movably inserted into the square hole 12 formed on the fixing plate 11, one end of the first air pipe 1 is fixedly installed with a pneumatic actuator 7, the other end of the first air pipe 1 is fixedly inserted into the first hole 10 formed on the lower housing 8, one end of the second air pipe 2 is fixedly inserted into the second hole 14 formed on the lower housing 8, the adjusting assembly 5 is composed of an internally threaded sleeve 18 and an annular protrusion 19, the annular protrusion 19 is fixedly installed on the inner wall of the lower side of the internally threaded sleeve 18, the annular protrusion 19 is rotatably installed in the annular groove 9, the internally threaded sleeve 18 is rotatably sleeved on the lower housing 8, the internally threaded sleeve 18 is simultaneously installed on the externally threaded upper housing 13 by threads, the fixing ring 20 on the sealing assembly 6 is fixedly sleeved on the lower housing 8, and the fixing ring 20 is simultaneously located below the fixing plate 11, the rubber sealing ring 22 is pressed against the upper end of the internally threaded sleeve 18 under the elastic force of the sealing spring 21. During the use process, the distance between the lower assembly 3 and the upper assembly 4 can be adjusted by rotating the adjusting assembly 5, so as to adjust the volume of the expander. The method is to simply rotate the adjusting assembly 5 on the lower housing 8 and the externally threaded upper housing 13. Since the adjusting assembly 5 is rotatably connected to the lower housing 8 and the adjusting assembly 5 is threadedly connected to the externally threaded upper housing 13, as the adjusting assembly 5 rotates on the lower housing 8 and the externally threaded upper housing 13, the lower assembly 3 and the upper assembly 4 will approach or move away from each other, and the square rod 16 will slide in the square hole 12.
