What is the function of the throttle valve used in the precision four-column hydraulic cutting machine?
The throttle valve used in the cutting machine controls the flow of the fluid by changing the throttle section throttle length. The parallel connection of the throttle valve the one-way valve can be combined into a one-way throttle valve. The throttle valve the one-way throttle valve are simple flow control valves. In the hydraulic system of the cutting machine quantitative pump, the throttle valve the safety valve cooperate with each other to form three throttle speed control systems: the intake throttle speed control system, the return throttle speed control system, the bypass throttle speed control system. The throttle valve has no flow negative feedback function cannot compensate for the speed instability caused by load changes. They are usually only used when the load change is small the speed stability requirement is high.
What is the function of the safety valve used in cutting machine manufacturers? The pressure relief valve is a hydraulic control valve, which mainly plays the role of setting pressure overflow, stability, system unloading safety protection in the hydraulic equipment of the cutting machine. When assembling using the safety valve, due to damage to the O-ring combined sealing ring, loose mounting screws pipe joints, it may cause bad leakage. If the cone valve the main valve core is worn too much, the sealing surface is in poor contact, it will also cause excessive internal leakage even affect normal operation. What is the function of the one-way valve of the cutting machine? The one-way valve, also known as the check valve, is used to prevent the reverse flow of oil in the hydraulic system of the cutting machine. There are two types of one-way valves: straight-through valves right-angle valves. The straight-through check valve is installed on the pipeline through a threaded connection. The right-angle check valve has a threaded connection, a plate connection a flange connection.
The hydraulic control check valve, also known as the locking valve the pressure-maintaining valve, is the same as the one-way valve, preventing the reverse flow of oil. However, when the oil flow needs to flow in the hydraulic circuit in the opposite direction, the oil pressure can be controlled to open the check valve to allow the oil flow to flow in both directions. The hydraulically controlled one-way valve uses a conical valve core with good sealing performance. When the oil pipeline needs to be closed, the valve can be used as a one-way locking device to maintain pressure. There are two ways to control oil leakage through a hydraulic one-way valve: internal external. The internal leakage type can be used in oil pipelines with no back pressure at the reverse outlet of the oil flow, otherwise the external leakage type must be used to reduce the control oil pressure.
