Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
Q:How do you explain A in butterfly valve D37A1?
Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy
Q:Types of butterfly valves
Butterfly valve structure categories: central to clip butterfly valve, central flange butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, eccentric butterfly valve, soft sealing butterfly valve, hard sealing butterfly valveButterfly drive categories: handle, worm gear, electric, pneumatic, electromagnetic, electromagnetic, hydraulic, electro hydraulic, hydraulic, hydraulic, pneumatic
Q:How to calculate the size of the manual butterfly valve?
[1] type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, valve body material, this is the most basic arrangement way now D341X-16C. [2]: butterfly valve 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 air water, steam, and all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. 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:Butterfly valve is generally used in what position?
It can also be used for switch control of low pressure pipeline medium.
Q:What's the difference between butterfly valves and check valves?
Butterfly valve is manual, only switch function.The check valve is an automatic valve, which prevents backflow of the pipe medium.
Q:Gate valve, butterfly valve and so on can do the valve so that?
Do a lot of use valve and butterfly valve, pneumatic / hydraulic, or electric device, automatic control valve, adjust its switch angle, so as to achieve the purpose of regulation. For example, in the factory, in order to ensure the top pressure, then the pressure regulating valve, the valve is automatically adjusted by a butterfly valve! And there is also pressure regulator, pressure regulator valve series is used independently. Of course the more, is mainly used to adjust the flow!
Q:What is the butterfly valve
Double valve technology is the use of large sets of small valve valve technology, place a small butterfly in the large butterfly valve, when feeding in a large number of double valves open at the same time, the material quickly added, when the material is in accordance with the set to a certain number, the valve automatically shut down, by a small valve to feed, until it reaches the requirements of the control system the number of closed, so as to ensure high precision batching material, thereby saving expensive raw materials.
Q:Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
Q:What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?
D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.
