However, if make the disc into a ball or ceramic ball, the problem is solution of the struggle. At the same time. Because the valve open and close between stroke is small, tightly closed surface can undertake repeatedly opening and closing again, because of this it is very suitable for use in demand more occasions of the switch. Its main material is brass. Because most of the Industrial Valves seat and valve disc is easier to repair or change, and when repair or change closely enclosed components don't need to put the whole valve removed from the pipeline, the valve and pipeline welding is very suitable for use as a body of occasions. Has research to create satisfaction of petrochemical, electric power, smelting metal, urban construction, chemical industry and other departments by the valve of various kinds of use of a variety of ways. Brass is also called copper zinc alloy, is one of the most commonly known as panax notoginseng brass, zinc and the proportion of pure copper. The lack of, however, as of valve is also couldn't help not value. Q: as of brass introduce a: brass as of valve is one of the globle valve series products. As of valve disc once away from the closed position, the seat and disc tightly closed surface, there is no longer contact between so it tightly closed surface mechanical abrasion of the very small, so its tightly sealed performance is good, lack is tightly closed surface is likely to be clamped between particles in the flow medium. ( 3) Typically on the valve body and disc is only one tightly closed surface, thus making craft is better, easy to maintenance. However, on the basis of body structure and stem't relatively, the layout of the export channel, this state is Marine valve can be improved. The want of it mainly flow resistance coefficient is larger, because the cause pressure losses, especially in the hydraulic device, the pressure loss is particularly apparent. The valve is closed ( The disc) Along the core line movement of the valve seat. Because open or close the valve stem travel relatively short, and have very good truncation function, and because of the changes in the seat of his stroke proportional relationship with the disc, very suitable for traffic regulation. Based on disc this way of moving, the seat of his change is relation with directly proportional valve stroke. This is caused by the ponder question to the closing of the valve torque. Because of its satisfactory mechanical properties and processability was widely to drink. The use of the valve is extremely widespread, but because of the opening and closing torque is larger, the structure length is longer, average nominal size limit under 250 mm, also have to 400 mm, but choose to believing the import direction. 。 Brass as of valve in the Marine valve were used more widely. By the time the valve is the most apparent strengths: ( l) In the process of opening and closing, because the disc and body tightly closed between the friction force is smaller than gate valves, and wear resistance. ( 2) Open highly common channels for seat diameter l / 4, because this is much smaller than gate valves. With the usual by the Industrial Valves does not have the strength. Ordinary omm under 15 by the medium of valve are mostly from the lower part of the disc into, and more than 2 o0mm as of the media are mostly from the top of the disc. The valve can be used in most medium flow in the system. Opened or closed in order to reduce torque, common above 2 o0mm globle valve are set by-pass within or outside the by-pass valve. Because the media through the change of the flow direction of the valve, because the globle valve minimum flow resistance is also higher than most of the scores of other types of valves. Because of this, this type of valve is very adapt to as truncation or adjustment and throttling. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
