How the classification of slide valve function

      Slide valve function of spool valve in the middle or the original position, the oil outlet valve is called spool valve function. Slide valve function directly influence the executive component of working state, slide valve function can meet the differentrequirements of different system. The correct choice of valvefunction is important.

     Classification

     According to the structure and movement characteristics,reciprocating and rotary slide valve is divided into two types.Reciprocating piston and a planar single valve, planar doublevalve and plunger type 3. Plunger type valve used in the hydraulicand pneumatic device. When the piston reaches the left limit position, spool drive shaft is driven, the piston position to the left,switching the fluid flow, the fluid pressure and flow of P1 B channel, enter the B ′ chamber pressure cylinder, the pistonmoves to the right, the fluid in a A chamber is returned to A and the flow outlet channel. When the piston reaches the right limit position, drive shaft and driven spool valve, the piston positionback to the right position.

       Thus, slide the piston pressure cylinderto complete a cycle of action reciprocating motion. This constant cycle, the piston automatically continuous reciprocating motion. If the valve drive shaft in the middle position, the piston movement to stop. The valve plane single valve spool valve by the pressure difference, the friction sliding surface of large, action is notsensitive, easy to wear.

Planetary Gearbox

       It is also because of the defects of the structure, can not be adjusted in the small flow range, so when the machine runs at low load, the economy will reduce. Planardouble valve flap valve to increase the valve), a flow regulatingvalve performance and stress situation has improved, but there are still shortcomings big friction. Plane type valve spool valve is mainly used for steam machine. Rotary slide valve advantages isswitching action quickly, accurately, and can fine tune, but the poor sealing. It is suitable for the pressure, temperature is not high.

The proper maintenance of control valve

      Control valve maintenance

      The control valve has the advantages of simple structure andreliable action, but because it is in direct contact with the process medium, its performance directly affects the quality and environmental pollution, so the control valve must be regular maintenance and periodic maintenance, especially for the use of harsh conditions and important occasions, more attention should be paid to repair work. Inspection of key parts:

     1.The inner wall of the valve body

For the use of control valve in the high differential pressure andcorrosive media occasions, diaphragm valve body wall,diaphragm valve often media impact and corrosion, we must focus on examination of pressure, corrosion of the situation.

      2.The valve seat

Control valve work, due to media penetration, fixed seat screw used in the inner surface susceptible to corrosion Ershi seat loose, inspection should be noted. Working under high pressure differential valve, check valve seat sealing surface is alsowashed.

      3.The valve core

     The valve to regulate the work of moving parts, by the media,erosion, corrosion is the most serious, when the repair parts to carefully check whether the valve is corrosion, wear and wear,especially in the case of valve pressure differential is moreserious (due to cavitation phenomena), should be noted. Valve replacement should be badly damaged, the stem should also pay attention to whether a similar phenomenon, or connected with the spool loosening.

       4.The diaphragm

     "O" - rings and other seals. Diaphragm control valve should be seized, "O" - shaped sealing gaskets are aging, cracking.

      5.Packing

     It should be noted PTFE packing, sealing grease is aging, with the surface is damaged, should be replaced when necessary.

Spring Chain Tensioner

     Regulating valve and control valve, the main types of actuators,by accepting the control unit regulating the output control signal,using power operated to change the fluid flow. Control valveactuator and valve are generally composed. If you press it with the implementing agencies use the power, control valve can be divided into pneumatic, electric, hydraulic and three, that is the source of compressed air powered pneumatic valve, using electricity as the power source of electric control valve, the liquid medium (such as oil) pressure powered electric hydraulic controlvalve and, in addition, according to their functions andcharacteristics, and electromagnetic valves, electronic, intelligent,fieldbus regulating valve.
