Q:What is the difference between ball valve Q41F-16C and Q41F-16P?
Q41F-16C ball valve material is carbon steel, Q41F-16P material is 304. No difference between the others. I hope you'll be satisfied.
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?
Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.
Q:What are the applicable conditions of ball valves?
This deformation can compensate the ball manufacturing accuracy and surface roughness, and ensure the sealing performance of the ball valve.Because the valve seat ring is usually made of plastic, so the choice of valve structure and performance, to consider the ball of fire and fire, especially in petroleum, chemical, metallurgy and other departments, the use of ball valve in the equipment and piping system of flammable and explosive medium, should pay attention to fire and fire.Usually, the double adjustment, strict sealing, slurry wear necking channel, the rapid opening and closing movement (1/4 turn open and close), high pressure cut-off (pressure difference), low noise, there is the phenomenon of cavitation and gasification, a small amount of leakage to the atmosphere,It is recommended that ball valves be used in piping systems with small operating torque and low fluid resistance.
Q:Is the ball valve the same as the float valve?
The answer upstairs is more accurate, I will add.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. float valve, that is upstairs to explain the kind of specific, you can refer to the toilet, which is used on the water supply device is this structure.The 3 threaded valve, threaded flange valve, valve flange welding flange or valve: This refers to the connection forms of body, such as your home with the water valve between the valve and pipeline is usually a threaded connection, then the other is threaded, welding, flange connection means.
Q:What does copper ball valve mean by "1/2"?
1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.
Q:What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?
Structure and characteristics of eccentric hemisphere valve1, a type: mainly for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and cost.2, side mounted: side mounted compact structure, valve quality light, applicable to the valve installation space requirements, the light valve of the leading product seems to be eccentric hemisphere valve!
Q:What does "2P" ball valve mean?
2P is made up of two parts. The price of 2P is higher than that of 1P, and its performance is good.
Q:Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball
There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.
Q:Daily maintenance and common maintenance of ball valves, Q347F-16C and Q41F-16C
Filler and sealing materials pay attention to point, basically no technical things
Q:Valve and ball valve is the same thing? Don't know don't speak
Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves
