Q:What's the use of fire butterfly valve?
Fire butterfly valve is the abbreviation of fire signal butterfly valve, which belongs to a kind of fire valve.Fire valve is an important accessory on the industrial and building pipelines. The fire fighting valve is composed of three parts: valve body, headstock gear and valve cover. Among them, the fire signal butterfly valve has the advantages of simple structure, reliable sealing, light opening, long life, convenient maintenance and so on. It is widely used in water supply and drainage, building, fire fighting systems, all kinds of pipelines, especially in fire lines.
Q:What do you mean, handle, butterfly valve, hard back and soft back?
The butterfly valve of the handle butterfly valve is 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 between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.
Q:Which is expensive, butterfly valve?
The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
D: for clamp, 3: turbine head 4: flange connection 1: vertical plate X5: Ding fine rubber 10/16: nominal pressure Z: gray cast iron valve body, B1: valve plate material is ductile iron
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:Transformer butterfly valve and pressure relief valve difference
I don't know. Let's have a Baidu! Baidu is powerful.
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:Gate valve, butterfly valve and so on can do the valve so that?
Valve can not be used to adjust the use, if the switch can not be in place, the medium flushing gate valve is easy to cause poor sealing!
Q:Where is the pcv valve in a 2001 ford focus?
Go around to the passenger side of the car and shove your arm way down along the firewall behind the engine. Feel around with your fingers and you will feel the PCV hose where it connects to the intake. Once you have found that you can follow it forward from underneath (no kidding) about a foot to the PCV valve. I don't think it is even visible from the top.
Q:unstick valves in 1988 volkswagon rabbit?
The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
