Q:What does the butterfly valve D361H - 25C DN350 mean?: Corrigendum: correct type: D361H-25 DN350Should not have C, nominal pressure above 1.6MP carbon steel valve material code name should be omittedValve: central vertical plate welded turbine butterfly valve, nominal pressure 25kg, caliber 350mm, body material, carbon steel, sealing surface material: Cr13 stainless steel

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:What kinds of butterfly valves are available? What is the working principle of butterfly valves?: At work temperature:(1) high temperature. T>450 degrees C butterfly valve.(2) medium temperature butterfly valve. 120 C<t<450 DEG butterfly valve.(3) normal temperature butterfly valve. A 40C<t<120 degree C butterfly valve.(4) low temperature butterfly valve. One 100<t< one, 40 degrees C butterfly valve.(5) ultra low temperature butterfly valve. T< one 100 degrees C butterfly valve. Www bgfm /df/Divided by connection:1 pairs of clip butterfly valveThe butterfly plate of the clip butterfly valve is installed in the direction of the diameter of the pipe. The valve is fully open.The clip butterfly valve is simple in structure, small in size and light in weight. 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.2, flange butterfly valveThe flange butterfly valve is a vertical plate structure, and the stem is a sealing ring of an integral metal hard sealing valveFor flexible graphite plate and stainless steel plate composite structure, mounted on the valve body, butterfly plate sealing surface of stainless steel surfacing. The sealing ring of the soft sealing valve is made of nitrile rubber and is mounted on the butterfly plate.3, lug butterfly valve4 、 welded butterfly valveWelding type butterfly valve is a non sealed butterfly valve, widely used in medium temperature less than building materials, metallurgy and mining, electric power production process at 300 nominal pressure 0.1Mpa pipe, used to open and close connected, or adjust the medium quality.

Q:I have a good set of #142 Pontiac heads with small diameter valves. I want to have the heads enlarged to accept the larger Pontiac valves, and I have the larger exhaust valves out of #13 heads and the larger intakes from 6X8 heads. The valves appear ok and shiny on the stems: If the valve is burnt there is no longer something you're able to do with it yet replace it. in the event that they simply desire cleansing up you could lap them in with a lapping compound the threat with this is which you would be able to desire to visual exhibit unit which you don't get close to to the sting of the valve, this is once you will finally end up with a burnt valve. The valve should not be flush with the valve seat this is plenty to close and the warmth of combustion could have an more advantageous effect on the textile.

Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?: Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.

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:Transformer butterfly valve and pressure relief valve difference: The butterfly valve is usually fitted with an oil immersed transformer between the tank and the radiator to control the flow of oil between the transformer tank and the heat sink. When large power transformers are delivered, the radiators are usually individually packed to reduce transport sizes. The butterfly valve is closed to prevent the outside air or water from entering the transformer tank. When the transformer is transported to the installation site, the radiator is installed on the butterfly valve one by one. When the radiator is installed, the butterfly valve can be opened so that the oil flow between the transformer, the oil tank and the radiator can be circulated, so as to play the role of heat dissipation.When the transformer is running, it is found that when the radiator has seepage, the butterfly valve can be closed to avoid further leakage of transformer oil, and a new radiator can be replaced.

Q:What is the effect of nylon coating on butterfly valve plate? Thank you: Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high

Q:Who was the first doctor to discover Pulmonary Valve Stenosis? Also, who was the first doctor to perform surgery for it? Please and thank you for your help.P.S. I have this condition.: 1761 - Pulmonary valvar or valvular stenosis is one of the more common forms of congenital heart malformations and it has been extensively studied since the original description of pulmonary valve stenosis by John Baptist Morgagni in 1761. 1888 - Tetralogy of Fallot, first characterized by Dr.Etienne Fallot in 1888, is present in about 3000 children born each year in the United States. It is a combination of four heart abnormalities. Dodrill and his colleagues employed it with success for the open correction of a stenotic pulmonary valve in October 1952.

Q:What's the difference between D71X-16 and D71H-16 butterfly valves?: Model D71X model means this, D represents butterfly valve, 7 represents butterfly connection form for clip type connection, 1 represents straight through, and 16 represents pressure 16 kg pressure.X stands for sealing and soft sealing, and the sealing surface is usually nbr.H stands for metal hard sealing, usually 2Cr13 surfacing.D71X-16 butterfly valve featuresIts main features are:1 、 the design is novel, reasonable, unique structure, light weight, fast opening and closing.2 、 small operating torque, easy operation, labor-saving and smart.3. It can be installed and maintained conveniently in any position.4, seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.5, sealing materials aging resistance, corrosion resistance, long service life and so on.
