- Q: What's the use of fire butterfly valve?
- Fire butterfly valve is the abbreviation of fire signal butterfly valve, which belongs to a kind of fire valve.Fire valve is an important accessory on the industrial and building pipelines. The fire fighting valve is composed of three parts: valve body, headstock gear and valve cover. Among them, the fire signal butterfly valve has the advantages of simple structure, reliable sealing, light opening, long life, convenient maintenance and so on. It is widely used in water supply and drainage, building, fire fighting systems, all kinds of pipelines, especially in fire lines.
- Q: Function of signal butterfly valve in fire sprinkler system
- The signal butterfly valve is connected with the fire alarm system to monitor the switch status of the valve, thus effectively preventing misoperation
- Q: What does butterfly valve do?
- 5, connections are flanged, wafer connections, welded connections and lugs on the clip connection. ?Drive in the form of manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage actuator, can realize remote control and automation.Advantages of butterfly valves1, opening and closing convenient, fast and labor-saving, fluid resistance is small, you can often operate. ?2, simple structure, small volume, light weight. ?3, to transport slurry, accumulation of fluid in the pipe outlet at least. ?4, under low pressure, can achieve a good seal. ?5, good regulating performance.Disadvantages of butterfly valve1, use pressure and working temperature range is small. ?2, poor sealing. ?Butterfly structure can be divided according to the bias plate, vertical plate, inclined plate and lever type. According to the form of sealing can be divided into soft sealing type and hard sealing type of two. The soft sealing type usually adopts rubber ring seal, and the hard sealing type usually adopts metal ring seal. ?By connection type can be divided into flange and clamp connections; press can be divided into manual transmission, gear transmission, pneumatic, hydraulic and electric types.
- Q: Should I connect the butterfly valve before and after the pump? Or gate valve?
- This situation should use gate valveBecause it has the following advantages:1, 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.Of course, there is also a multi-functional pump control valve is also very good, dedicated to the water supply system. Connection URL: (Reference), you can look at yourself, and I hope to help you.
- Q: i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II
- well depends .. how far the piston was down and if the valve is still in the valve guide. intake you may have to pull the intake and feed it up from the intake port .. exhaust .. pull the manifold and feed it back up from the exhaust port.. and last .. pull the head .. if the the valve is still in the guide and the piston is not at the top .. you may could turn the engine slowly by hand to the top the piston may push up the valve up . you may be able to pull the valve up then..
- Q: For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious
- The direction of the arrow on the valve body is cast, refers to the flow of media, users see the arrow, the arrow direction according to the logical and installation, this installation has become a habit, it is easy to accept the installation instructions, according to the national standard is not what error. But in the eccentric butterfly valve is installed so that sometimes there will be some problems, said the following example: according to the flow of eccentric butterfly valve with the medium flow consistent installation, tube medium is liquid, after the valve is closed, if the original direction of medium inlet pressure, reduced or zero, the export of medium reflux reflux, if senior supply, resulting in the high pressure medium, the pressure is greater than the inlet pressure, the valve will be subjected to reverse pressure, because the hard seal butterfly valve as a one-way valve so that the use is not conducive to sealing butterfly valve, and there will be leakage.
- Q: can't locate freon intake valve for 03 jaguar an was wondering were it is located at
- Most manufacturers put the fill nozzle on the hoses, either the high or/and the low side. Also, the low side can be found on the accumulator.
- 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: What's the difference between electric butterfly valve and electric two way valve?
- The electric two way valve is specially used for the fan coil of the central air conditioner. It is usually used in conjunction with the temperature controller. It can realize the automatic regulation of temperature. But the electric butterfly valve and the electric control valve belong to a kind of variety, and they are important execution units in the field of industrial automation control.
- Q: Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!
- Not at all a big expense most places should do it for $90 -150 including the gasket . Takes me about an hour to do one. If you don't adjust them eventually you could wear the cam possibly although I've never seen any issues from not doing it. If they are too tight then possibly they could've got the engine hot . If they are too loose which is what they should do as they wear they'll just be a little noisy until you get them adjusted if I can help in any other way please let me know hope this helps
