Q:What are the uses and classifications of manually operated clip butterfly valves?
In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees -90 degrees between, when rotates to 90 degrees, the valve opens the card completely. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also applied to the cooling water system of thermal power stations.
Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
At work temperature:(1) high temperature. T>450 degrees C butterfly valve.(2) medium temperature butterfly valve. 120 C
Q:What do D71, D371 and D341 represent in butterfly valves?
D71 stands for middle line to clip butterfly valveD371 represents the worm wheel centerline pair clip butterfly valveD341 stands for worm gear flange butterfly valve
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:butterfly valves d7a1x5
D71x-1.6? Or D371X-1.6, do you need butterfly valves for production or butterfly valves? The question perplexed us all.
Q:The difference between butterfly valve and gate valve
Butterfly valve role, butterfly valve is used to open and close disk type reciprocating rotation of about 90 degrees to open, close or adjust the flow of a medium valve. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, the driving performance of torque is small, simple operation, rapid, high chemical corrosion, and can also have good flow control function and closure characteristics, the use of butterfly valve is very extensive.
Q:How to calculate the size of the manual butterfly valve?
I don't know what size you mean, and what about DN in diameter, such as DN125, which means 125 cm in diameter
Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.
Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
D: for clamp, 3: turbine head 4: flange connection 1: vertical plate X5: Ding fine rubber 10/16: nominal pressure Z: gray cast iron valve body, B1: valve plate material is ductile iron
Q:Especially butterfly valve
Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the opening or closing or adjustment; actuators have electric or pneumatic, and so on, through the transmission device to drive the stem, valve plate rotation;
