Q:Are fire fighting signal valves and signal butterfly valves the same thing?
The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
Q:How do hydraulic butterfly valves work?
The valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. Sorry, the picture doesn't come up
Q:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.
Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.
Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Butterfly valve switching speed, fluid resistance is small, but the flow control is not good, suitable for only fast opening and closing occasions. Control valve switching speed is relatively slow, fluid resistance, but the flow control of the linear good, suitable for flow control requirements of the occasion.
Q:What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
Double eccentric butterfly valve: in the single eccentric butterfly valve on the basis of further improvement of forming, is the most widely used double eccentric butterfly valve. The structure features that the center of the stem deviates from the center of the disc as well as the center of the body. The effect of the double eccentric valve can be opened immediately after the disc from the valve seat, substantially eliminating the unnecessary disc and valve seat over squeezing, scratching phenomenon, reduce the resistance from the open, reducing the wear and improve seat life.
Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
Worm gear flange butterfly valve, also known as worm gear flange plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.Butterfly valve structure is simple, small size, light weight, only by a few parts. 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. Butterfly valve plate installed in the direction of the diameter of the pipe. 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. When the flange butterfly valve is in the fully opened 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 that the flow control characteristic is better. Butterfly valve with bullet sealing and metal sealing two seal type. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.
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:What does the model D373H-16C of butterfly valve mean?
For example: Z543H-16C bevel gear flange plate valve, nominal pressure 1.6MPa, the valve body is made of carbon steel valves valve name according to the mode of transmission, connection form, structure, lining material and type name. But here in the name of the content shall be omitted: (1) the connection form: "flange" (2. Structure: a): valve "rod" and "flexible" and "rigid" and "single gate"; B: "straight" stop valve and throttle valve; C: ball "floating" and "one-stop"; D: butterfly valve "vertical plate type"; E: the diaphragm valve "roof"; F: Cock "filler" and "one-stop"; G: check the "one-stop" and "single"; H: "safety valve is not closed. (3) the valve seat sealing surface material in the material name Said. I have just engaged in the valve industry, mainly to do www.ssfmsh.com traps, but also hope that we learn from each other and make progress together
Q:How to use the fire butterfly valve properly?
Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
