- Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
- Q:It is different from the butterfly valve butterfly valve
- How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. The main sealing element is a sealing ring, and the material is selected according to the use and the medium.
- Q:Butterfly valve medium flow direction of the provisions of it?
- The direction of the arrow on the valve body is cast, refers to the flow of media, users see the arrow, the arrow direction according to the logical and installation, this installation has become a habit, it is easy to accept the installation instructions, according to the national standard is not what error. But in the eccentric butterfly valve is installed so that sometimes there will be some problems, said the following example: according to the flow of eccentric butterfly valve with the medium flow consistent installation, tube medium is liquid, after the valve is closed, if the original direction of medium inlet pressure, reduced or zero, the export of medium reflux reflux, if senior supply, resulting in the high pressure medium, the pressure is greater than the inlet pressure, the valve will be subjected to reverse pressure, because the hard seal butterfly valve as a one-way valve so that the use is not conducive to sealing butterfly valve, and there will be leakage.
- Q:D what's the meaning of "one 71x one 1 butterfly"?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
- 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 valve use
- Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for 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.
- Q:What is the difference between the installation and function of a butterfly valve and butterfly valve?
- The principle of the valve gate valve is open and close cases, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface forming wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing. Gate valve with the stem along with a straight line of motion, called the lift rod gate valve is also known as the bar gate valve. Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust. When opening the valve, when the gate lift height is equal to 1:1 times of the valve path, the passage of the fluid is completely unblocked, but at run time, this position is unable to monitor. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position.Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
- Q:Butterfly valve flow direction is single or two-way?
- Hello, soft sealing butterfly valve is generally two-way flow, large bore with flow direction is one-way flow. Hard sealed butterfly valves are the same.
- Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
- Liu1964tg, this guy is right, don't know, don't mislead everybody
- Q:Butterfly valve network and ordinary butterfly what is the difference?
- 1. The butterfly valve of the pipe network adopts an eccentric structure. When closed, it has the function of closing and tightening. The sealing performance is reliable. After opening and closing, the cover is completely sealed, and the cover is completely out of contact, so as to ensure that the sealing surface is not damaged.2, 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 a single space, can be installed in the any direction.
