What is the function of the one-way valve of the cutting machine? I believe this is the doubt of many people. The following is introduced by Qixin shoe machine accessories - cutting machine production, cutting machine manufacturing and cutting machine manufacturers.
Check valve, also known as check valve: used to prevent reverse oil flow in the hydraulic system of cutting machine. There are two types of check valves: straight through type and right angle type. The straight through check valve is installed on the pipeline with threaded connection.
Right angle check valve has three forms: threaded connection, plate connection and flange connection. The hydraulic control check valve of four column cutting machine is also called locking valve and pressure maintaining valve. It is the same as the check valve to prevent the reverse flow of oil. However, when the reverse flow of oil flow is required in the hydraulic circuit, the control oil pressure can be used to open the check valve so that the oil flow can flow in both directions. The hydraulic control check valve adopts conical valve core, so it has good sealing performance.
When the oil circuit is required to be closed, this valve can be used as one-way locking of the oil circuit to maintain the pressure.
There are two kinds of oil leakage modes of hydraulic control check valve: internal leakage type and external leakage type. Internal leakage type can be used in the oil circuit without back pressure at the reverse outlet of oil flow; Otherwise, an external leakage type is required to reduce the control oil pressure.
