Commonly used in clamping, control, lubrication oil passage. There are direct acting and pilot type of points, the use of pilot type. Hydraulic transmission fluid pressure to element ﹑ flow and direction control. Wherein the control pressure is called the pressure control valve to control the flow is called flow control valve to control the direction of the pass ﹑ called off and flow control valves. Divided by use of ﹑ relief valve and sequence valve. (1) relief: to control the hydraulic system to maintain a constant state when it reaches the set pressure. Called safety valve relief valve for overload protection. When the system fails, the pressure was increased to potentially damaging limit value, the valve opens and overflow port to ensure the safety of the system. (2) The valve: control branch circuit stable than the primary circuit oil pressure depression. It controls the pressure relief valve according to different functions can be divided into setting valve (output pressure at a constant value) ﹑ fixed differential pressure relief valve (input and output pressure difference value) and fixed ratio valve (input and output pressure to maintain a certain ratio between). (3) the sequence valve: enables an execution element (such as a hydraulic cylinder ﹑ hydraulic motor, etc.) after the operation, and then make the other actuator action sequence. Pressure generated by the pump cylinder 1 to promote sports, through the inlet valve action sequence in area A, when the hydraulic cylinder 1 is moved fully into the pressure rises, the upward thrust in the area of ??A is greater than the spring it is set After the value of the intake port spool rising oil outlet communicating with the hydraulic cylinder 2 is moved. By adjusting the flow control valve orifice area between the valve and the valve body and local resistance to the traffic it generates adjusted to control the speed of movement of the actuator. Flow control valve according to use is divided into five species. (1) Throttle: After set-orifice area, it makes little change in load pressure and velocity of movement of the actuator even less demanding remained largely stable. (2) control valve: When the load pressure changes to maintain the pressure drop of the throttle valve is constant. Thus, the orifice area it is set in the future, no matter what the load pressure changes, control valve can maintain constant flow through the throttle valve, so that the movement speed of the actuator is stabilized. (3) The shunt valve: two actuator load regardless of size, can receive the same oil source is equal to the same amount of traffic as synchronous shunt valve or valves; receive a distribution in proportion to the ratio of the flow diverter valve. (4) flow valve: the role of the shunt valve contrary, flowing into the manifold valve flow prorated. (5) shunt flow valve: both shunt valve and flow valve two functions. Directional control valve use is divided into one-way valve and valve. Check valve: Allow only way turned fluid in the pipeline, to cut off the reverse. Valve: change through different pipes ﹑ off relationship between the two, minute ﹑ number three and so on according to the spool valve in the operating position; according to the number of channels controlled by a two-way communication ﹑ ﹑ ﹑ Stone Five-and so on; according to the spool drive mode sub-manual ﹑ ﹑ hydraulic motor, electrically powered and so on. Figure 2 is a three way valve works. P for the supply mouth, O is back to the oil port, A ﹑ B is the gateway to the actuator output. When the spool is in the neutral position, all ports off, the actuator does not move; when the spool is moved to the right position, P and A pass, B and O pass; when the spool is moved to the left position, P and B pass , A and O pass. Thus, the actuator will be able to make a positive ﹑ reverse movement. The late 1960s, on the basis of the several hydraulic control valves on and developed the electro-hydraulic proportional control valve. Its output signals (pressure ﹑ flow) can continuously change with the input. Electro-hydraulic proportional control valve according to the role of different, accordingly divided into electro-hydraulic proportional pressure control valve ﹑ electro-hydraulic proportional flow control valve and electro-hydraulic proportional directional control valve. http://www.zffmc.com/ http://www.51079178.com/ Tel: 021-51079178 Mobile: 13681810483 E-mail: shzffmc@126.com Fax: 021-51079178 QQ: 648239308 http: //www.zffmc .com /
