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:Why use special flanges for butterfly valves?
Because to use special flange butterfly valve butterfly flange diameter is just the butterfly inside diameter of DN coincides with a slot in the back, and this is the connection of the steel pipe is inserted into the slot, so as to ensure the sealing effect, but with a flange piece of ordinary cannot guarantee the effective sealing effect.Butterfly valve plate installed in the direction of the diameter of the pipe. Butterfly valve structure is simple, small size, light weight. Consists of only a few components. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better.If the butterfly valve is used as a flow control, the main thing is to correctly select the size and type of valve. Butterfly valve structure and principle, especially suitable for making large-diameter valves. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve. The clip type butterfly valve is a double headed bolt connecting the valve between the two pipe flanges. The flange type butterfly valve is provided with a flange on the valve, and a bolt is used to connect the flanges at the ends of the valve to the pipe flange.
Q:Buried extension butterfly valve is buried directly, or need to repair the valve well?
It's better to get a valve well for future maintenance.
Q:What is the meaning of American Standard butterfly valve B series
American Standard flange connection is divided into A, B series. A series for normal flanges, B series for compact flanges. 24 "to no AB series, flange standards for B16.5, 24" above B16.47.
Q:When will Butterfly Valves be used?
Butterfly valve is the most common and most widely used in the field of the valve, cases of sewage treatment, water supply, iron and steel, building construction and heating fields needs a lot of valves, especially with the hard seal butterfly valve butterfly valve position and a lot of popularity, the field is used more widely.
Q:What's the use of fire butterfly valve?
Its working principle is as follows:1, the signal butterfly drive by the worm gear drive shaft and butterfly plate rotation, realize the opening and closing and control flow.2, rotating worm gear drive handwheel, so that the butterfly plate to open and close and adjust the flow of purpose, hand wheel clockwise rotation for the valve closed.3. The worm gear drive box is equipped with micro switches in two forms:A, in the gear box body is provided with open and close direction two microswitches, respectively, when the valve fully open and close action, connected to the control room "valve open" valve off "light source, to accurately display the switch state of the valve.B, the transmission device is arranged in the box body the microswitch (disc position close to 0 degrees), when the butterfly plate from 0 degrees to 40 degrees when the position of a micro switch, the output valve closed signal, 40 degrees to 90 degrees when the position of another pair of normally closed output valve opening signal. A cam that adjusts the touch microswitch and shows the different positions of the disc.The fire in the fire that is the switch signal butterfly valve in the pipe network, because the fire pipe water must be kept clear, so as to ensure the timeliness of fire, so the signal valve once closed, will tell the host signal module alarm, fire control network notify the monitoring center is closed.
Q:Butterfly valve general use occasions
Valve is especially suitable for low differential pressure, large diameter, large flow of gas and slurry liquid. For general control valve, DN300mm is big valve, only individual to DN450, and for the butterfly valve, DN500 below is a small valve, DN500 ~ 1000 is the standard valve, the largest butterfly caliber up to 9m. Visible, large diameter pipe with the main butterfly valve.
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:Classification of telescopic butterfly 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. (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. (1) high temperature butterfly valve. T>450 C butterfly valve
Q:What is the D37-10Q butterfly valve?
D- butterfly valve (valve type); 3- worm (drive); 7- pairs of clamp (connection); 10-PN1; nominal pressure of 10 kg; Q- ductile iron (valve body material).
