Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
Liu1964tg, this guy is right, don't know, don't mislead everybody
Q:Timing belt reason for bent valve?
A TDI has no valve to piston clearance as a results of the indisputable fact that's a diesel and has a extreme compression ratio. i'm a mechanic myself and hate to slam different techs yet it truly is clearly a screw-up on his section. There are some issues that would have exceeded off even if the shop he works at is to blame for the damages. If the tensioner did bend (which I surprisingly doubt exceeded off) then he has recourse by the business business enterprise that man made the tensioner yet to be quite truthful, it truly is only no longer real. similar is going for the snatch problem. that only isn't plausible. good success.
Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
What's the difference between a worm valve and a manual butterfly valve?The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching.
Q:1 valve bugle fingering chart? (more complicated than it sounds)?
This Site Might Help You. RE: 1 valve bugle fingering chart? (more complicated than it sounds)? 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...
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: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?
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. According to type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, material of valve body, regulate butterfly valve type.
Q:D341W-10P-400 butterfly valve, what does each alphanumeric letter mean?
According to JB/T308-2004 "valve type programming method"D butterfly valve3 worm gear4 flange connection1 Structure: sealed type, central vertical plateW sealing material for valve body material10 nominal pressure PN10P body material is chromium nickel stainless steel400 shall be nominal size DN400
Q:Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
3. kinds of butterfly valve:According to the connection mode: flange type, clip type.According to the material of sealing surface, soft seal and hard sealing.According to the structural form, butterfly valves can be divided into the following types:Plate typeInclined plate typeOffset plateLever type4. butterfly valve features:(1) the structure is simple and the shape is small. The utility model has the advantages of compact structure, short structural length, small size and light weight, and is suitable for large caliber valves.(2) the resistance of the fluid is small, and when the valve is fully opened, the valve seat passage has an effective circulation area, so the fluid resistance is smaller.(3) open and close, convenient and quick, good adjustment performance, butterfly plate rotation 90 degrees can be completed headstock. By changing the angle of rotation of the disc, the flow can be graded.(4) the opening and closing moment is smaller, because the butterfly plate on both sides of the rotating shaft is basically equal to the medium, and the opposite direction of the torque is generated, so that the opening and closing is more labor-saving.(5) low pressure sealing performance, sealing surface materials generally use rubber, plastic, sealing performance is good. Limited by the material of the sealing ring, the pressure and the temperature range of the butterfly valve are smaller. But the use of hard sealing butterfly valve pressure and temperature range has been greatly improved.
Q:The difference between the directly buried gate and the flange valve and butterfly valve
The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.Butterfly valve refers to the closure of parts (valve or butterfly plate) as 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. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
