Q: How many kinds of butterfly valves are there?: What's the score?There are central butterfly valve, double eccentric butterfly valve, three eccentric butterfly valveAnd according to the materialAnd according to the way of connection

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: Okay, so I've been thinking about trying to learn how to play my dad's baritone bugle, but I have no idea how to. If anyone had a good fingering chart for it, that would be great. The bugle has one valve and a trigger. I am a natural flute player and percussionist, so this is my first time playing a brass instrument. Needless to say I am very confused. Call me a noob, I don't care, as long as you get me a fingering chart for a 1 valve baritone bugle. Please help. :): Starting below the staff in treble clef - G - open (yeah, intonation heck) C - open D - valve (gap) F# - rotor G - open or valve (gap) Bb - Rotor valve B - Rotor OR valve (pick it) C - open C# - both D - valve D#(Eb) - rotor E - open F - valve F# - rotor G - open G#(Ab) - both (yech!) A - valve or rotor Bb - open or both B - valve or rotor C - open anything above C - dial it in. After seeing this, you'll know why going from G-D to G-F was such a radical improvement. After playing on this relic, you'll really appreciate what some of those corps had to do to sound good.

Q: I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.: top of the manifold

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: How warm is the PTFE butterfly valve?: The normal temperature can be kept at 120 degrees and the instant temperature is 150

Q: Should I connect the butterfly valve before and after the pump? Or gate valve?: 1, valve, the fluid resistance is small, the sealing surface by the erosion of small and medium Chong brush. 2, opening and closing more effort. 3, medium flow unrestricted, no disturb, do not reduce pressure. 4. The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide. Butterfly valve main deficiency is that it uses the pressure and temperature range is small. And poor sealing. Therefore, the gate valve should be preferred.Gate valve (gatevalve) is a gate valve used to open and close parts, and along the vertical axis of the valve seat movement, in order to achieve the opening and closing action of the valve. The valve can only be fully open and fully closed, opening and closing parts is the gate, the direction of motion perpendicular to the direction of the fluid, valve two square I-shaped sealing surface forming the wedge, the wedge angle varies with the valve parameters, usually 5 degrees is not high, medium temperature is 2 degrees 52'. Improve the process of valve, make up the sealing surface angle in the process of production deviation, this kind of gate is called flexible gate.

Q: CAD drawing of butterfly valve: Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.

Q: What type of valve does the butterfly valve D343X DN300 represent?: D butterfly valve, 3 worm gear, 4 flange type, 3 should be three eccentric X body, sealing surface for rubber, DN300 caliber 300MM

Q: Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?: 5. butterfly valve structureButterfly valve mainly by the body, butterfly plate, stem, sealing ring and transmission components.(1) the valve body is cylindrical, and the upper and lower parts each have a cylindrical boss for installing the valve stem. Butterfly valve and pipe flange connection, such as the use of clamp connection, the minimum length of its structure.(2) stem, stem is the axis of the butterfly plate, shaft end adopts stuffing box sealing structure, can prevent leakage of medium. The upper end of the valve stem is directly connected with the driving device to transmit the torque.(3) the butterfly plate is the opening and closing part of butterfly valve.
