BUTTERFLY VALVE FLANGE DOUBLE ECCENTRIC DUCTILE IRON DN80- DN1200

Q: What is the difference between turbine butterfly valve and flanged butterfly valve?: Their models are different, the structure is different, they are the main driving part, different worm gear and straight rod distinguish, all belong to the flange valve.

Q: The difference between butterfly valve d71x_10s and d341s-10: Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.

Q: What is the electric butterfly valve? Please, great God!: Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve.

Q: What is an electric two position butterfly valve?: Answer for you:Shanghai Huquan electric valve manufacturer of electric double position butterfly valve this product is connected with the flange clamp. Material: cast iron, carbon steel, stainless steel, 304/316Product overviewElectric double position butterfly valve (soft seal) is suitable for temperature less than 200 DEG C, adjust the flux and closure of the role of the medium nominal pressure is less than 1.6MPa of food, medicine, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipeline.main features1., the design is novel and reasonable, unique structure, light weight, fast opening and closing.2., small operation torque, easy operation, labor-saving and smart.3. can be installed in any location, easy maintenance.4., seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5., sealing material aging resistance, corrosion resistance, long service life and so on.Electric double position butterfly valve adopts standardDesign standard: gb/T12238-1889Flange connection size: gb/T9113.1-2000; GB/T9115.1-2000; jb78Structure length: gb/T12221-1889Pressure test: gb/T13927-1992; jb/T9092-1999

Q: The flow ratio of area and maximum flow area of the valve is? If it refers to the opening of the valve rotation angle? Butterfly linear closure refers to the butterfly valve at constant angular velocity close? When the change trend of flow is what? These valves problem bothering me for a long time,: Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;

Q: What is the principle of butterfly valve and check valve? Any difference?: Direct water butterfly valve, check valve is to water can not flow valve

Q: Where are the exhaust valves, mud valves and butterfly valves?: The exhaust valve is suitable for the pipeline with working medium, so as to improve the efficiency of the water conveyance equipment and protect the pipe from deformation and rupture. Sludge discharge valves are suitable for use in floating waste water treatment plants, such as gypsum. Slag, scale power stations, smelters, sugar mills.

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: 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: Which is expensive, butterfly valve?: The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
