Q:Daily maintenance of ball valve
The new parts need to be cleaned before assemblingThe assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities, foreign matter contamination, adhesion or remain in part into the cavity on the surface or, if the packing is micro discharge, to lock the stem nut.Note: do not lock too tight, usually lock 1/4 circle to 1 laps, the leak will stop.(A) disassemblyMake the valve in a half open position, flush and remove dangerous substances that may exist inside and outside the valve body.Close the ball valve, remove the connecting bolts and nuts on both sides of the flange, and then remove the valve completely from the line.In order to remove the drive - actuator, a connecting bracket, lock washer, stem nut, butterfly spring, glam, wear plates, valve stem packing.Remove the body cap connecting bolts and nuts, separate the valve cover from the valve body and take off the valve cover washer.Make sure the ball is in the "off" position, which can be easily removed from the valve body and then removed from the valve seat.A hole in the body downward nudge stem until completely removed, and then remove the packing ring and the O.Caution: Please operate carefully to avoid galling, stem surfaces and body packing box seals.B) reassembleCleaning and inspection of the parts removed, it is strongly recommended to use spare parts package replacement valve seat and valve cover, gaskets and other seals.Assemble in reverse order of disassembly.Cross the locking flange bolts with the specified torque.Lock the stem nut with the specified torque.
Q:What's English for ball valves?
Check valve/ball vavle/globe valve (ball valve), there are three kinds of translation, see which you preferFast stainless steel ball valve, ball valve is evolved from the plug valve. It has the same rotation, 90 degrees lifting action, and the difference is that the cock body is a sphere and has a circular through hole or passage through its axis. The ratio of the sphere to the channel opening should be this, i.e., when the ball rotates 90 degrees, the spherical surface should be fully presented at the inlet and outlet, thus truncating the flow. The ball valve only needs to rotate 90 degrees of operation and very small turning moment can close tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel. It is generally believed that the ball valve is suitable for direct opening and closing, but the development of the ball valve has been designed to make it throttling and controlling the flow.
Q:Family aluminum tube ball valve, with a long handle so that, or butterfly shaped handle so that?
Where can I distinguish it from the handle?!!In simple terms, the heavy ones need to wear a little longer
Q:3/43/8 above the ball valve is not usually said of the big ball valve?
Ball valve above the 3/4, 3/8, refers to the ball valve connector, thread connection water pipe diameter, 3/4, 3/8 is the pipe diameter of the British size, 3/4 is 6 in charge, equivalent to 19.1 mm diameter; 3/8 is 3 in charge, 9.5 mm. Of course, the larger the ball valve, the greater the diameter.
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:Open the pressure relief valve core hole with what
Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution.
Q:What are the uses and characteristics of copper ball valves?
Copper ball valve features:1, suitable for regular operation, quick and easy to open and close.2, fluid resistance is small.3, simple structure, relatively small size, light weight, easy maintenance.
Q:Is the ball valve ball valve?
The hemisphere valve has two kinds, one is no eccentric, the valve seat is always close the valve, the valve must be made (such as the V type ball valve etc.).
Q:Switch valve type, switch valve, ball valve or butterfly valve is good
Ball valve and butterfly valveBall valve is 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.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.
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.
