Q:Why is the butterfly valve used for fire control?
1, this is a good question, it seems that this has not yet made a unified standard requirements, a bit confused2, personal understanding of fire water supply pipe, pipe shall be installed on the valve, because the valve is fully open all closed features of fire control system is usually required is fully open, easy management features are obvious.3, fire water supply system is also useful to butterfly valve, but mainly signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
Q:How big is the butterfly valve with a diameter of 80?
80 caliber butterfly valveAskIn practice, this is not the case. Why not use it when I use it?. However, I used 65 butterfly valves, right? WhyChasing the answerWhat's the thickness of your pipe?
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: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:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
Eccentric butterfly valve and ordinary butterfly valve, when the butterfly valve is opened, the eccentric butterfly valve sealing surface will reduce great wear, in the opening, the disc will leave the valve at the first time the sealing surface!
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
The clip type valve bolts are generally longer, in high temperature conditions, bolt expansion may lead to leakage, so the high temperature conditions are not suitable for large diameter.But for the end and downstream pipeline occasions need to remove the clip on butterfly valve is generally not, because when the downstream flange dismounting clamp down, the valve will fall down, it must do in order to remove the nipple, and the flange type butterfly valve does not exist on the surface of the problem, but the cost will be relatively high.
Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
What's the difference between a worm valve and a manual butterfly valve?The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching.
Q:Especially butterfly valve
Butterfly valve is fully open to fully closed is usually less than 90 degrees, the opening refers to the butterfly plate rotation angle;Linear closing should be the locator is linear, if the potentiometer is 0-10 euro, corresponding to 0-90 degrees, 500 Europe, opening 45 degrees;
Q:What are the functions and uses of butterfly valves?
Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear.Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.
