Description: The spring of the first-stage intake and exhaust valve of a natural gas compressor is an elastic wear-prone part inside the first-stage valve of a reciprocating compressor. It is installed between the first-stage valve lift limiter and the valve plate, driving the plate to return and close, and is adapted to the natural gas compression conditions of the first-stage cylinder.
It provides pre-tightening force so that the opened valve plate returns quickly to fit the valve seat, preventing gas backflow in the cylinder and ensuring intake, compression, and exhaust cycles of the first-stage cylinder.
It buffers the impact of valve plate opening and closing, controls the opening lift of the plate, and reduces impact fatigue damage to the plate.
It ensures that the valve plate responds sensitively to gas pressure differential changes, stabilizing the working pressure of the first-stage cylinder and maintaining the compressor gas delivery capacity.
Helical compression springs, with several springs evenly arranged around the circumference; fatigue-resistant alloy spring steel is selected for natural gas conditions, being resistant to oil and gas corrosion and adaptable to alternating pressure and temperature; the spring stiffness matches the pressure differential of the first-stage cylinder, and the springs in the same group are consistent in height and elasticity.
