5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.
3. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
- Q: What's the difference between the three eccentric butterfly valve and the two eccentric butterfly valve?
- Double eccentric butterfly valve refers to: valve plate and central axis partial, simply said that there are two parts of the butterfly valve.Three eccentric butterfly valve, there are three places are biased
- 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 many kinds of butterfly valves are there?
- Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. 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.[structure]The utility model is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a butterfly plate.
- 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: Butterfly valve general use occasions
- Butterfly valveAlso known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. 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.
- Q: Function of signal butterfly valve in fire sprinkler system
- The signal butterfly valve is connected with the fire alarm system to monitor the switch status of the valve, thus effectively preventing misoperation
- Q: Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
- One is the turbine drive and the other is with the handle
- Q: Butterfly valve network and ordinary butterfly what is the difference?
- Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
- Q: What type of valve does the butterfly valve D343X DN300 represent?
- D- butterfly valve, 3- worm drive, 4- flange connection, 3- three eccentric, X- soft seal, DN300- nominal size is 300, the full name is 300 of the three eccentric butterfly valve, and I hope to help you.
- Q: How do the butterfly valves d341 and d343 differ in appearance?
- D341 is a wedge type single gate structureThe D343 is a parallel single gate structure
