wafer check valve---2009-10-19
Wafer check valve drive is to use external power open and close needle-valve device. The purpose of using the drive is to make effort to facilitate the operation of the valve Šp fast and reliable, or to achieve automatic control and remote control. Right valve drives the basic requirements are: torque, or thrust to meet the needs of open and close the valve on the itinerary and torque control of accurate and reliable, dynamic selection of appropriate on-site conditions, open and close actions comply with control requirements, the device itself light small.
wafer check valve drive unit according to the output shaft movement pattern is divided into many parts of rotary Šp reciprocating rotary and linear three kinds. Multi-turn or multi-turn rotary type, suitable for stem or stem nut need to turn Multi-turn in order to fully on or off the valve, ball valveŠp globe valve, the output torque value is a series of generally 40 ~ 10000 cattle meters (20 to 1100 kN thrust). Part of the Rotary for the rotation lap of the stem will be able to fully on or off within the valve, ball valve Šp butterfly valve, the output torque of the series is generally 125 ~ 125,000 Nm. Linear reciprocating stem Zhizuo applies to linear reciprocating motion will be able to fully on or off valves such as solenoid valves.
wafer check valve drive unit according to the power source can be divided into manual installations or gear transmission device, pneumatic device, electrically powered hydraulic installations or installations or Gas-oil installations or electro-hydraulic linkage devices. The most primitive and most simple valve drive device is a hand-wheel, handle. With the needle valve and the large-scale automation of production processes, for a variety of needle valve drives the need for more and more. Needle valve drive automation in industrial production occupies an important position.
