Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
In addition to the three common, flange standard complex, a long story.All kinds of standards, there is a little difference in thickness, diameter of flange, bolt hole number, but the flange bolt hole parameters of the same pressure level (bolt circle diameter K, bolt diameter L, bolt number N) are the same.
Q:What is the maximum temperature resistance of the 304 stainless steel ball valve?
What seal do you have?.PTFE sealing maximum temperature: 120 degreesMetal seal maximum temperature: 325-400 degrees, look at the manufacturers.
Q:Gate valve, ball valve, the difference between the pressure regulating valve
The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve. The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by. When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem.
Q:What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
Ball valve (in the field of marine engineering and ships should be cut-off valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve to rotate the valve movement.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.Ball valve was introduced in 1950s, with the rapid development of science and technology, production process and product structure of continuous improvement, in a short span of 40 years, has rapidly developed into a major valve category. In western developed countries, the use of ball valves is increasing year by year.
Q:What's the advantage of using an electric ball valve?
The electric ball valve uses electric control, not very suitable in very dangerous conditions, the electric ball valve belongs to the valve control, remote control, manpower, and convenient, and now all the enterprises have to use the valve in the automatic control to change
Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
1, the valve body and the valve cover as a whole bear cavity, must meet the design manual on the minimum wall thickness requirements, at the same time to add corrosion allowance, at the same time calculation, large value as the wall thickness of 2, then according to the height of gate valve diameter, to ensure that the valve in the fully open under the condition, ensure the seal and the valve cover seal gate, so that we can determine the height of
Q:What do you mean by ball valves dn20pn1.6rf?
DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve
Q:Hard sealing ball valve, what method can calculate the leakage?
Valve leakage level is actually the valve sealing class. There are two kinds of GB and American Standard.
Q:PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?
Not a thing, gate valve, globe valve, ball valve for the installation of dark valve, suitable for buried wall installation, I hope my answer can help you, Shanghai Rui River group Liaoning branch
Q:DN15 ball valve with a bit of outer wire
We normally say 4 points, 6 points, 1 inches, corresponding to 152025
