Valve pneumatic device is safe, reliable, low cost, easy to use and maintenance, is a major branch of the valve drive structure. At present, pneumatic devices have more applications where explosion-proof requirements. Valve pneumatic device using gas source pressure is low, generally not more than 0.82MPa. Because the size of the structure should not be too large, so the total thrust of the valve pneumatic device can not be great. First, the valve pneumatic device conditions of use Conditions of work Air pressure 0.4 ~ 0.7 (MPa) Ambient temperature and medium temperature 5 ~ 60 (℃) Piston working speed and blade diameter line speed 10 ~ 500 (mm / s) Electromagnetic control input Signal current 4 ~ 20mA Second, the classification of pneumatic valves Valve Pneumatic devices according to their structural characteristics are divided into three types: film pneumatic device, pneumatic cylinder or device, pneumatic swing device. In addition there are pneumatic motor pneumatic device. Pneumatic Device Classification Film Type 1, Film Cylinder 2, Diaphragm ①Disk Diaphragm ② Flat Diaphragm 3, Spring 4, Piston Rod Cylinder 1, Cylinder ①Single Cylinder ② Double Cylinder 2, Piston and Piston Ring ①O-ring Ring ② J-ring ③ U-ring ④ V-ring 3, Piston rod 4, Manual operating mechanism 5, Air line accessories ①Circuit system ② Signal return circuit ③ Air filter ④ Pressure reducing valve Oil mist eliminator ⑤ Control Valve swing type 1, the cylinder 2, the stator 3, the rotor 4, the blade Third, the structure of various types of pneumatic devices Pneumatic device structural features Type Features Thin film stroke, <40mm, compact, flexible, manual cylinder Long stroke, if necessary, need to add cushioning mechanism, the output is not enough Dual cylinder structure, manual and manual pneumatic switch structure Swing structure is simple, low cost, reciprocating motion directly into a rotary motion Air motor can directly replace the valve Motor and become a pneumatic device, which can have the function of the electric device such as torque control, but the structure is complicated Search this: More Valves Product Info Gas source pressure 0.4 ~ 0.7 (MPa) Ambient temperature and medium temperature 5 ~ 60 (℃) Piston working speed and blade radial velocity 10 ~ 500 (mm / s) Electromagnetic control input signal current 4 ~ 20mA Film type 1, (1) Disk diaphragm (2) Flat diaphragm (3) Spring (4) Piston rod cylinder type (1) Cylinder (1) Single cylinder (2) Double cylinder (2) Piston and piston ring ①O-ring ② J-ring ③ U-ring ④ V-ring 3, Piston rod 4, Manual operating mechanism 5, Accessories for air circuit ①Circuit system ② Signal return circuit ③ Air filter ④ Pressure reducing valve Oil mist eliminator ⑤ Control valve swinging type 1, Cylinder 2, stator 3, the rotor 4, the blade type features film-type stroke is short, <40mm, compact structure, flexible, without manual cylinder stroke, if necessary, need to add cushioning mechanism, the output is less than double cylinder structure, manual and manual pneumatic switch structure Swing structure is simple, low cost, reciprocating motion directly into a rotary motion Air motor can replace the valve motor directly into a pneumatic device, which can have the electric device torque control and other functions, but the structure is complex
Outer Coil Storage Tank
1. Use:
Outer coil mixing tank is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and scientific research field.
2. Notes:
1) According to user`s different requirements,there are many mixing methods(anchor, paddle, pan wheel, push, or box-type stirring )to choose.
2) There are five kinds of heating way,including the jacket heating , coil heating, electric heating,steam heating,and the heat transfer oil heating.
3)The user can choose the explosion-proof device,the sealing device, positive pressure or negative pressure inside the Reactor.
