A Lubricator for Pneumatic Triple Parts

Abstract

The invention relates to the field of aerodynamics and provides a lubricator for a pneumatic FRL (filter regulator lubricator) unit. The lubricator comprises a lubricator body, an oil cup is arrangedbelow the lubricator body, the outer surface of the oil cup is hermetically connected with a seal part, and the outer peripheral surface of the seal part is hermetically connected with the lubricatorbody. The left side of the lubricator body is provide with an air inlet, the right side of the lubricator body is provided with an air outlet, the lubricator body is internally provided with a cavity,and the interior of the cavity is communicated with the air inlet and the air outlet. The lubricator has advantages that when a piston moves below a vent hole, pressure air in the cavity enters the oil cup through the vent hole, and the pressure of air in the oil cup is increased to enable oil discharging of an oil discharging device; when the internal air pressure of the oil cup is increased, the piston is driven to move up under the supporting action of a supporting spring, and the piston moves above the vent hole to effectively protect the oil cup from being damaged by strong air pressure.

Description

technical field [0001] The invention relates to the field of air transmission, in particular to a lubricator for pneumatic triple parts. Background technique [0002] Pneumatic triple parts are used in pneumatic technology. The assembly of three air source processing components: air filter, pressure reducing valve and lubricator is called pneumatic triple part. During the pressurization process, it is sent to the interior of the moving parts of the body for lubrication. [0003] During the working process of the lubricator, the air pressure in the cavity between the air inlet and the air outlet is relatively high. In order to let the lubricating oil inside the oil cup drip, a large air pressure needs to be passed into the oil cup. The pressure difference between the oil ports can drip the lubricating oil in the oil cup. When the strong air pressure inside the lubricator suddenly enters the oil cup, it is likely to damage the oil cup. There is a one-way valve to prevent bac...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a lubricator for a pneumatic triple unit, which solves the problem that when the strong air pressure inside the lubricator suddenly enters the oil cup, the oil cup may be damaged, and the oil suction pipe may be damaged. Generally, there is a one-way valve to prevent backflow. The setting of the one-way valve makes the lubricator prone to clogging, and it is difficult to unblock the clogged oil pumping mechanism.
