- 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: How big is the butterfly valve with a diameter of 80?
- With the 80 caliber 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 flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid.
- Q: What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
- D341 is flanged connection center plate butterfly valve under pressure 1.0MPa-1.6MPa ZB1 rubber soft seal
- Q: Model specification for butterfly valves
- 1. classification by structure(1) Central sealed butterfly valve (2) single eccentric sealed butterfly valve (3) double eccentric sealed butterfly valve (4) three eccentric sealed butterfly valve2. by secret cover material classification(1) soft sealing butterfly valve. (2) metal hard sealing butterfly valve.3. classified by seal type(1) forced sealing butterfly valve (2) pressure sealed butterfly valve. (3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.4. classification by work pressure(1) vacuum butterfly valve. Butterfly valve with lower working pressure than standard atmosphere. (2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa. (3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa. (4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve. (5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.5. classification by operating temperature(1) high temperature butterfly valve. T>450 degrees C butterfly valve (2) medium temperature butterfly valve. 120 C6. classification by connection1 pairs of clip butterfly valve2, flange butterfly valve (3) lug butterfly valve. (4) welded butterfly valve.
- Q: What are the butterfly valves models?
- Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.
- Q: Butterfly valve switch direction respectively?
- First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.
- Q: Butterfly valve in the use of the difference? Caliber?
- According to the function and use of the valve and butterfly valve, gate valve, small flow resistance, good sealing performance, the valve plate and the flow direction of the medium is the vertical angle, if the valve is not in place in the valve plate switch, wash medium on the valve plate of the valve plate is easy to fibrillation, according to valve seal damage.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.
- Q: D what's the meaning of "one 71x one 1 butterfly"?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
- Q: Which is more expensive, gate valve or butterfly valve?
- Gate valves of the same material and specifications are much more expensive. The weight of the gate valve is much heavier than that of the butterfly valve.
