Description

Air inlet and exhaust valve and piston sleeve integrated sealing mechanical structure of compressor

Technical Field

The utility model relates to a compressor technical field, especially a compressor intake and exhaust valve and piston sleeve body seal mechanical structure.

Background

Compressor air valve air compressor is an important component of the compressor that controls the timely intake and exhaust of gas into and out of the cylinder. The air valves on the piston compressor are all automatic valves, namely the opening and closing of the air valves are realized by the pressure difference (the air pressure difference in the air cylinder and the valve cavity) on the two sides of the valve plate instead of a forced mechanism. Commonly used automatic valves include ring valves, mesh valves, strip valves, reed valves, butterfly valves, and straight flow valves, each of which is divided into an intake valve and an exhaust valve. The valve seat is provided with a gas channel which can be covered by the valve plate, closes an air inlet (or exhaust) channel together with the valve plate and bears the pressure difference between the inside and the outside of the cylinder; a valve plate alternately opening and closing the valve seat passage; the spring pushes the valve sheet to fall to the valve seat when the valve is closed, and inhibits the valve sheet from impacting the lift limiter on structures such as a strip valve, a reed valve, a direct current valve and the like when the valve sheet is opened, and the valve sheet has elasticity and plays a role of the spring; the lift limiter limits the lift of the valve plate and is often used as a part of the bearing spring.
