Q:It is different from the butterfly valve butterfly valve
It should be the same. Butterfly valve (also called butterfly) English Name: butterfly valve: headstock disc disc disc plate and can rotate around the axis of the valve body of a valve rotating. Construction: mainly composed of valve body, valve stem, disc and sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a plate.
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:Fire, the signal butterfly valve flange connection or welding?
Fire signal butterfly valve is generally used to clamp type connection more, the clip type butterfly valve body is without flange, that is to say, with two flanges on the pipe, then screw the butterfly valve. Followed by the butterfly valve itself with flanges, and then the pipe flange with screws connected, this is the flange connection. Fire welding less use, pressure is not high!
Q:What's the difference between turbine butterfly valve and manual butterfly valve?
Butterfly (Manual butterfly) butterfly plate installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped disc rotates around the axis. The angle of rotation is between 0 and -90 degrees. When rotating to 90 degrees, the valve is fully open.Butterfly valve structure is simple, small size, light weight, only by a few parts. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better. Butterfly valve has an elastic seal and metal seal, two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
Q:What does "10" in the butterfly valve "D71X-10" mean?
The pressure of 10 kg 1.0MPA is usually cast iron
Q:What is an electric two position butterfly valve?
It's an electric valveProduct brief:  Electric double position butterfly valve, this product is connected with flange type, clip type. Material: cast iron, carbon steel, stainless steel, 304/316Product overview   Electric 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 reasonable and novel design, unique structure, light weight, rapid opening and closing.2 operating torque is small, easy to operate, saving smart.3 can be installed in any position, convenient maintenance.4 seals can be replaced, reliable sealing performance to achieve two-way seal zero leakage.5 sealing material aging resistance, corrosion resistance, long service life etc..Electric double position butterfly valve adopts standardDesign standard: GB/T12238-1889Flange size: GB/T9113.1-2000; GB/T9115.1-2000; JB78Length: GB/T12221-1889Pressure test: GB/T13927-1992; JB/T9092-1999
Q:Are fire fighting signal valves and signal butterfly valves the same thing?
The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
Q:How do the butterfly valves d341 and d343 differ in appearance?
D341 is a wedge type single gate structureThe D343 is a parallel single gate structure
Q:How many kinds of butterfly valves are there?
1. according to the structure classification (1) Central sealing butterfly valve (2) single eccentric sealed butterfly valve (3) double eccentric sealed butterfly valve (4) three eccentric sealed butterfly valve2., according to the sealing material classification (1) soft sealing butterfly valve. (2) metal hard sealing butterfly valve.3. according to the form of sealing classification (1) forced sealing butterfly valve (2) pressure sealed butterfly valve.4. classification according to working pressure (1) vacuum butterfly valve. 2) low pressure butterfly valve. (3) medium pressure butterfly valve. (4) high pressure butterfly valve. (5) ultra high pressure butterfly valve.5. classification by working temperature (1) high temperature butterfly valve. (2) medium temperature butterfly valve. (3) normal temperature butterfly valve. (4) low temperature butterfly valve. (5) ultra low temperature butterfly valve.
Q:What is an ERG valve?
If initially the codes confirmed that the EGR valve grew to become into defective and grew to become into no longer replaced this might smash the o2 sensor. whilst the EGR is caught open simply by fact of carbon strengthen the engine is taking in extra air it is coming from the blistered gases out of the exhaust and re burning them interior the process the EGR. The O2 sensor will examine this gases passing interior the process the exhaust and point out a lean mix of gasoline and could sign the ECM to strengthen the gasoline to the engine.consequently after a time of employing with mistaken mixtures the o2 sensor will fail. My suggestion is to change the EGR and the O2 sensor then highway try the vehicle.then have the codes rechecked. additionally if the engine isn't working mushy this might reason the transmission to act up.verify that the vacuum hose is linked to the modulator valve on the decrease back of the transmission. some transmissions have a working laptop or computer on a separate circuit interior the device and if the engine isn't working solid computer will p.c.. up the incorrect sign and transmission won't shift properly.. solid good fortune oh and the vehicle ECM or computer isn't your difficulty.
