Pneumatic actuator exhaust device reduces wear on its inner wall
The exhaust hole of the pneumatic actuator is generally a simple 1/4 or 1/2 inch copper silencer, but the poor environment of dust, corrosive gas, steam condensate and other conditions in the field environment leads to the corrosion and blockage of the exhaust hole of the actuator and poor exhaust. In addition, after the muffler corrosion perforation, pollutants enter the actuator cavity, corrode and wear the inner wall or rubber film of the actuator, affecting the normal operation of the pneumatic actuator. Especially the quick action and quick on-off valve of safety interlocking device affect the safe and efficient operation of the production device.
Technical implementation elements:
The technical problem to be solved by the utility model is the exhaust device of the pneumatic actuator, which can prevent the exhaust hole of the pneumatic actuator from being corroded, blocked and contaminated into the actuator, leading to the internal corrosion and wear of the actuator and ensuring the normal operation of the pneumatic actuator.
In order to solve the above technical problems, the technical solution of the utility model is as follows: a pneumatic actuator exhaust device including a shell, the shell is connected with the pneumatic actuator through a connecting pipe, the upper end of the shell is provided with a connecting pipe, and the shell is provided with a silencer.
The connecting pipe and the shell, the connecting pipe and the pneumatic actuator are connected by thread.
The connecting pipe is a bent pipe with a 90° bending section.
The shell is a hollow variable diameter structure with openings at the upper and lower ends, and the diameter of the outer circle of the horizontal section increases gradually from top to bottom.
The enclosure is provided with a muffler mounting thread ring, the inner wall of the muffler mounting thread ring is provided with internal threads, and the muffler is fixed on the muffler mounting thread ring by thread connection.
The muffler comprises a separator net and a silica gel dehumidifying adsorbent arranged at one end of the muffler mounting threaded ring near the muffler.
The pneumatic actuator exhaust device provided by the utility model has the following beneficial effects:
(1) The reducer shell can prevent dust impurities in the external environment from entering the actuator, and effectively avoid dust wear on the inner wall of the actuator;
(2) The vapor condensate in the environment also adheres to the shell due to the attraction of the molecules. When a certain amount is reached, it naturally drops to the ground or is adsorbed by the silica gel dehumidification adsorbent filled in the muffler to ensure that the air entering the actuator is dry and avoid the corrosion of the actuator.
