Brief Introduction of Pneumatic Cast Iron Wafer Butterfly Valve:
Butterfly valve is mainly consisted of body, stem, disc, seat and driver(lever, gearbox, pneumatic and electric Actuator) and so on.
On off and controlling flow of valve are made by turning stem and disc together.
Suitable Medium:Water, sewage,sea water, air, foodstuff, oil etc.
Operator:Suitalbe for handles(dn50~300), gear operators, electric and pneumatic control actrators
- Q:What are the classification criteria for pneumatic butterfly valves?
- The channel of the valve body inner surface smooth, fluid resistance, high CV value, strong circulation, moderate torque, the use of four seal structure and elastic rubber gasket seat with SI in high temperature aging on the outside sealing surface, zero leakage medium.Pneumatic butterfly, characteristics, there is a slit leaving the valve seat, the product is suitable for use in poor air circulation environment.The pneumatic telescopic butterfly valve is characterized in that the novel and reasonable design, unique structure, light weight, convenient operation, open and close rapidly; in addition to the telescopic valve for regulating and throttling effect, compensation pipeline temperature generated by thermal expansion and contraction function, but also for the installation of valve replacement and maintenance convenience. The sealing parts can be adjusted, replaced, sealed, reliable and so on.
- Q:Butterfly valve D71X-16 and D71X-16Q what is the difference?
- The two difference is that the body of the material is not the same, 16 behind with no sign, expressed as a default, is carbon steel (usually C), if you need to specify material, just behind with symbols, such as Q nodular cast iron, stainless steel P.
- Q:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
- Axis is not the same, so fast reaction, small wear.
- Q:What is the meaning of American Standard butterfly valve B series
- American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
- Q:Gate valve, butterfly valve and so on can do the valve so that?
- Yes, but the accuracy of the adjustment is not high. Just about. To adjust the flow, please use flow control valve.
- Q:Butterfly valve in the use of the difference? Caliber?
- According to the function and use of the valve and butterfly valve, gate valve, small flow resistance, good sealing performance, the valve plate and the flow direction of the medium is the vertical angle, if the valve is not in place in the valve plate switch, wash medium on the valve plate of the valve plate is easy to fibrillation, according to valve seal damage.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
- Q:How can I get the fire signal butterfly valve?
- 1, the signal butterfly drive by the worm gear drive shaft and butterfly plate rotation, realize the opening and closing and control flow. 2, rotating the handwheel worm gear to the disc to open and close and adjust the flow to the handwheel clockwise rotation for the valve closed. 3, worm gear is arranged in the box body micro switch has two forms: A, in the gear box body is provided with open and close direction two microswitches, respectively, when the valve fully open and close action, connected to the control room "valve open" valve off "light source, the quasi it shows the state of the valve switch. B, in the driving device is arranged in the box body the microswitch (disc position close to 0 degrees), when the butterfly plate from 0 degrees to 40 degrees when the position of a micro switch, the output valve closed signal, 40 degrees to 90 degrees when the position of another pair of normally closed output valve opening signal. A cam that adjusts the touch microswitch and shows the different positions of the disc.
- Q:Does the pneumatic butterfly valve need electricity?
- Yes, for emergency power off, use the 24V power belt with pneumatic butterfly coil to allow pneumatic valve to work
- Q:How to use the fire butterfly valve properly?
- Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
- Q:How is the lug butterfly valve connected to the flange?
- When installing, pay attention to the butterfly plate. The sealing ring between the flange face and the butterfly valve is tightened. After clamping, it can be tightened.
