BUTTERFLY VALVE DOUBLE FLANGED DUCTILE IRON DN50- DN1200

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 common faults and treatment methods?: Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.

Q: What does "C" in D971F-16C DN450 RF mean for electric butterfly valves?: Valve carbon steel -16c body 316 stainless steel -16r

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's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?: Stop valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to the amount of adjustment is also very suitable for convection.Check valve: also known as counter flow valve, check valve, back pressure valve or one-way valve, such valves are dependent on the flow of the pipeline itself flow force and automatically open and close, belonging to an automatic valveButterfly valve: it is a kind of valve which uses disc type opening and closing parts to turn back and forth about 90 degrees to open, close and adjust the passage of fluidGate valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material is different in various media. The valve, the valve is the most widely used.

Q: oil coming from valve into turbo charger: Diesels do not have pcv valves. Pcv valve are on gas engines only.

Q: valve adjustment 2001 chev prism 1.8L: valve adjustment . you need to know the fire order. the gage between the stem. rotators the cranshaft. it could be cold start. cylinder need to be bottomed center.

Q: DN80 flange butterfly valve, DN80 flange butterfly valve DN80, flange butterfly valve DN80 what is the difference?: Of course there are differences, the general market sales of the DN80 are many flange plate copper rod butterfly valve, quality can not reach the national standard, to use copper rod copper butterfly valve quality is king.

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.
