Q: Gate valve, ball valve, the difference between the pressure regulating valve
Gate valve and stop valve are shut-off valve, is the most common two valves. From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious. Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions.
Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?
*DN25 nominal diameter 25MM*PN18 nominal pressure 18 kg / cm2
Q: The toilet water pipe valve is broken, with a new twist, how are the screw does not move, then they told me to go on to the pipe on the water and then tighten, did as he said, really screwed, but do not know why, please tell the master what is the principle, if it is water without water when the screw does not move, but when the water can twist. What a kink!Is the water valve normal, a pull rod, pulling it back flush, do not rush the kind, the middle is a hollow ball
This is because the ball valve in the factory after the test pressure, after the ball valve pressure test, there is a vacuum, and the ball core and gasket pressed.When the pipe is loaded, the ball core and the sealing surface are slightly moved by the water pressure, so the taxi is opened. There is no vacuum in the inner part of the opening. Ball valve is good to use.A pressure test valve is not open for the first time.
Q: Is the water inlet valve good or the ball valve well?
Water valve at home as far as possible not to use the form of valve, gate valve for water, slag better, shut down with the next valve and ball valve. Just don't buy cheap goods, cheap ball valves use a period of time, gland leakage, spool corrosion must be replaced.
Q: 3/4 on the elbow of the water pipe. How about that ball valve?
3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material
Q: Is the two piece ball valve in the direction of the pressure pipe?
Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
Q: What are the advantages of an air operated ball valve in comparison with other types of valves?
In full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, will not cause the valve sealing surface erosion.Wide range of applications: diameter from small to a few millimeters, large to several meters, from high vacuum, high pressure can be applied. As the ball valve has a wipe in the opening and closing process, it can be used in suspension with solid particles in the medium.High processing accuracy: expensive, high temperature should not be used, such as impurities in the pipeline, easy to be blocked by impurities, leading to the valve can not open.
Q: Is the ball valve ball valve?
Therefore, strictly speaking, eccentric hemisphere valve ball valve, butterfly valve is more like a ball valve.
Q: Q41F-16-64P this is the ball valve, what type, please answer in detail, thank you!
Q--- ball valve4---- flange connection1----- ball valve is floating ball (ball valve has floating ball and fixed ball points, 7 represents the fixed ball)F----PTFE- PTFE seal (PTFE PTFE),16-64---- ball valve nominal pressure is 16-64 kg (1.6-6.4Mpa)P---- ball valve body material is 304 stainless steel
Q: That is to say, there is still a difference The man in the workshop said it was one thing... It's completely confusedHere are the data for the two valves. Please consult with the experts.Ball plug valve, high temperature cast steel, A216Gr.WCB flange, two pass, full quantity type 3, X 150LB RF ball / rod, 13%Cr seat, PTFE handle openBall valve Q41F-150LB-3"
Ball valve refers to the valve for the sphere of the valve, the English BALL VALVE, ball plug valve should be said that the plug valve, the disc is like a plug like, PLUG VALVE in english,
