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
Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
Divided by way of drive(1) electric butterfly valve(2) pneumatic butterfly valve;(3) hydraulic butterfly valve;(4) manual butterfly valve;In the form of structure:(1) Central sealed butterfly valve(2) single eccentric sealed butterfly valve(3) double eccentric sealed butterfly valve(4) three eccentric sealed butterfly valve;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.
Q:Butterfly valve in use when should pay attention to what problems?
In the process of using the butterfly valve, you should timely notice valve state, without excessive loosening, no abnormal leakage, or abnormal high temperature and so on, if there is abnormal, should immediately close the valve, to identify the reasons for the problem, treatment after use, it is also very important.
Q:Transformer butterfly valve and pressure relief valve difference
I don't know. Let's have a Baidu! Baidu is powerful.
Q:What is the electric butterfly valve? Please, great God!
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.
Q:How much is the Honeywell butterfly DN300?
Find the agent or find a reliable valve plant a lot of foreign brands are in Chinese OEM so find a reliable factory is relatively good service to keep up
Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:What is the butterfly valve
From the working principle of double butterfly valve can be seen that the operation is simple and easy to use, almost no wearing and maintenance compared with traditional ingredients.
Q:Does the pneumatic butterfly valve need electricity?
Yes, for emergency power off, use the 24V power belt with pneumatic butterfly coil to allow pneumatic valve to work
Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers
