The throttle valve used in the cutting machine controls the flow of the fluid by changing the throttle section or the throttle length. The throttle valve and the unidirectional valve in parallel can be combined into a unidirectional throttle valve. Throttles and one-way throttles are simple flow control valves. In the hydraulic system of the quantitative pump of the cutting machine, the throttle valve and the safety valve cooperate with each other to form three kinds of throttle speed regulating system: intake throttle speed regulating system, return throttle speed regulating system and bypass throttle speed regulating system. The throttle valve has no flow negative feedback function and cannot compensate for the unstable speed caused by load change. They are usually only used when the load changes are small or the speed stability is not high.
What is the function of the safety valve used in the home of the cutting machine manufacturer? Pressure relief valve is a hydraulic control valve, mainly in the cutting machine hydraulic equipment to set the pressure overflow, stability, system unloading and safety protection role. When assembling or using the relief valve, undesirable leakage may result from damage to the o-ring and combination seals, or from loose mounting screws and pipe connections. If the cone valve or the main valve core wear too much, or the sealing surface contact is poor, will also cause internal leakage too large, even affect the normal work. What is the function of the cutting machine one-way valve? One-way valve, also known as one-way valve, is used to prevent the reverse flow of oil in the hydraulic system of cutting machine tools. There are two kinds of one-way valve: straight - through valve and right - Angle valve. The straight through one-way valve is installed on the pipe through a threaded connection. The right-angle one-way valve has threaded connection, plate connection and flange connection.
Hydraulic control one-way valve, also known as lock valve and pressure valve, is the same as one-way valve, to prevent the reverse flow of oil. However, when the reverse flow of oil is needed in the hydraulic circuit, the oil pressure can be controlled by opening the one-way valve so that the oil flows in both directions. Hydraulic control one-way valve with a cone valve core, good sealing performance. The valve can be used as a one-way locking device to maintain pressure when the pipeline needs to be closed. There are two ways to control a leak through a hydraulic one-way valve: internally and externally. The internal leakage type can be used in the pipeline with no back pressure at the reverse outlet of oil flow, otherwise the external leakage type must be used to reduce the control oil pressure.
