Air outlet check valve used for air dryer

Abstract

The invention belongs to the field of drying equipment, in particular to an air outlet check valve used for an air dryer. The air outlet check valve comprises an exhaust port. A first air inlet and asecond air inlet are formed in two sides of the exhaust port. Expanded filtering channels are formed below the first air inlet and the second air inlet. Valve elements are arranged below the expandedfiltering channels. Springs are arranged below the valve elements. A valve element guide base is arranged on the other side of each spring. According to the air outlet check valve used for the air dryer, a novel structure is ingeniously designed based on the aerodynamic principle, so that the problem of frequent opening and closing of an original air outlet check valve is solved, and loud noise isavoided; and the air outlet check valve used for the air dryer is simple in structure, stable and efficient.

Description

technical field [0001] The invention belongs to the field of drying equipment, in particular to an air outlet check valve for an air dryer. Background technique [0002] The check valve is an automatic valve that prevents the medium from flowing backwards. After the existing air outlet check valve on the market is opened, the valve core in the chamber will open and close at a high rate, resulting in abnormal system noise and a huge impact sound. At the same time, due to the high-frequency fluctuation of air pressure, the flowmeter connected to the outlet It is also impossible to measure normally, so there is an urgent need for a stable and efficient air outlet check valve that does not produce high-frequency opening and closing phenomena. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel air outlet check valve which is stable and efficient and does not produce high-frequency opening and closing phenomenon ...
