Q: does it come in when you go over a certain rpm or do the valves change depending on how far you depress the throtle?
The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
Q: Butterfly valve use
Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. 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: When will Butterfly Valves be used?
Butterfly valve is the most common and most widely used in the field of the valve, cases of sewage treatment, water supply, iron and steel, building construction and heating fields needs a lot of valves, especially with the hard seal butterfly valve butterfly valve position and a lot of popularity, the field is used more widely.
Q: What does butterfly valve nps12cl150d373f4-150lb stand for?
NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
Q: I have 1993 Seville 4.9. I got a new EGR valve but it didn't help. I tested it with vacuum pump, it won't hold pressure at all, same with old one. Is that new EGR valve bad or just different type of EGR that vacuum pump won't work? Thanks!
HI i have question is all EGR valve work the same ? I Have an 86 Rx7 and when I test the EGR valve is doesn t hold pressure. So I m curios are they different from other vehicle due to is a rotary engine or due they all work the same. Thank You.
Q: What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
Q: Butterfly valve network and ordinary butterfly what is the difference?
Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
Q: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.
When talking about car engines, references such as v4, v6, v8, v10 and v12 are not for the number of valves. it is for the number of cylinders. The more cylinders that an engine has, the more fuel it consumes and most of the time, the more horsepower it can make. There are exceptions to this though. Regarding the noise of the engine, i would agree that a v8 sounds very good when it is roaring. Valves are actually the openings for fuel to get into the cylinders and the exhaust to come out from. Most modern engines have two valves for incoming fuel and two valves for the exhaust making a total of four valves per cylinder. hope that clears it for you
Q: Butterfly valve sealing material has several?
Butterfly valve sealing material has nine kinds:X1 (natural food gum);X2 (Heipalen);X3 (ethylene propylene rubber);X4 (chloroprene rubber);X5 (Ding Qing rubber);X6 (abrasion resistant rubber);X7 (fluorine rubber);X8 (silicone rubber);X9 (heat resistant ethylene propylene rubber).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.
