Description: The spring of the third-stage intake and exhaust valve of a natural gas compressor is an elastic wear-prone part inside the valve. It is assembled between the third-stage valve lift limiter and the valve plate and works with the plate to complete the opening and closing action, adapting to the high-pressure natural gas compression conditions of the third-stage cylinder.
It provides pre-tightening force to push the valve plate back into position quickly for closing, preventing the compressed gas from flowing back.
It limits the opening lift of the valve plate, buffers the impact of opening and closing, and reduces impact fatigue damage to the plate.
It ensures that the valve plate responds sensitively to pressure differential changes, ensuring stable intake and exhaust cycles of the third-stage cylinder and maintaining the compression pressure and gas delivery volume.
Helical compression springs, mostly composed of several small springs arranged together; high-temperature resistant and fatigue-resistant alloy spring steel is selected for high-pressure natural gas conditions, being resistant to oil and gas corrosion, with stiffness matching the pressure differential conditions of the third-stage cylinder; the spring dimensions and elasticity are strictly selected according to the equipment technical requirements.
