- Q: What's the use of fire butterfly valve?
- You should ask the signal butterfly valve, butterfly valve in the fire signal system which is a monitoring alarm signal, its purpose is to ensure that the valve has been opened in the daily state, to prevent misuse operation was closed, thus affecting when accidental fire extinguishing. Therefore, it is necessary to set up the signal valve!
- Q: Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
- D--- stands for butterfly valves; 4--- refers to the form of flange connections; 1--- refers to the valve stem and disc in the center of the valve line, without eccentricity; w--- refers to the valve seat material and body material is the same, usually carbon steel. The final 1--- refers to the nominal pressure of 1 kg / cm2.
- Q: What's the size of the signal butterfly valve sleeve?
- The output signal is stable and reliable for a long time. The valve has an electric node, which is drawn out to the control center by signal line, and the signal line voltage is 12V. In fact, the valve is open and closed, there is a signal to the consumer control center, easy to monitor, the valve in addition to the electric node, with the ordinary valve is not much difference, there are also signal butterfly valve. When setting a quota, cover a valve, and then set 13-156.Door closer, 7-194 and 13-1013.Fire phone 7-188.Fire radio 7-382
- Q: Gate valve and butterfly valve which is installed when there is a direction?
- Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.
- Q: Seat has said to the previous owner that the car needs a new air mass meter and dump valve.I am putting a new air mass meter on it.Does it have a dump valve.I know very little on this subject.
- every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.
- Q: How does the pneumatic butterfly valve control the angle of opening?
- The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator
- Q: Do you use the straight stem butterfly valve in the fire fighting engineering?
- Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
- 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: What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
- General large bore turbine.What is the difference between worm gear pair butterfly valve and center line worm gear butterfly valve?The structure is the same, but the model is different, the central line refers to the butterfly valve, an eccentric structure (371), the clip butterfly valve can do 371, you can do 373, etc.. In more detail, the clamp can be a midline type, 1 single eccentric, 2 double eccentric, 3 is 371372373 midline, then it can be flange connection, it can also be a pair of clamp connection
- Q: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- Three eccentric hard seal butterfly valve quality standards, up to zero leakage, but you mean the end of the direct discharge?If so, that's OK. First you have to calculate how much the pipe fluid pressure is.For example, the pipe fluid pressure is highest and the pressure is 1.6MPa (16 kg)Should choose three eccentric hard seal butterfly valve should be pressure 1.6MPa (16 kg)If you worry, optional 2.5MPa (25 kg) will not leak!Answer: three eccentric hard sealing butterfly valve can be installed at the end of the pipe
