2. Globle valve uncomfortable or used for larger particles, viscosity, easy to medium of coke. 3. By the valve tightly closed, tightly closed between friction force is small, the survival of the fixed number of year is longer than the other. 。 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. Has research to create satisfaction of petrochemical, electric power, smelting metal, urban construction, chemical industry and other departments Marine valve by valve of various kinds of use of a variety of ways. The valve can be used in most medium flow in the system. According to the flow of media, have straight through the valve, once-through ended by the end of valve and Angle type. 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. 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. 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. 3. The valve regulation performance is poorer. By the valve in tightly closed way points, there are packed tightly closed tube tightly closed as of valve by valve and pattern. Because most of the valve 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. However, on the basis of body structure and stem't relatively, the layout of the export channel, this state is capable of improvement. 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. Based on disc this way of moving, the seat of his change is relation with directly proportional valve stroke. Use the valve by valve refers to shut down a ( The disc) Along the core line movement of the valve seat. 3. The flow of media should be direction of the arrow shown in exactly the same with the valve body. The lack of the valve as follows: 1. Open and close the valve fluid resistance is big, the required force is larger. The category by the valve according to the position of the stem turnbuckle points within a turnbuckle type of valve, turnbuckle type of Industrial Valves. Because of this, this type of valve is very adapt to as truncation or adjustment and throttling. This is caused by the ponder question to the closing of the valve torque. 2. The handwheel, handle and wei motivation, for sling is not allowed. The valve installation and protection should be paid attention to the following projects: 1. The handwheel, handle operation of the Industrial Valves can be installed on no matter what position of the pipeline. 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. 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. Q: as of the valve has the following advantages: a: 1. By the valve has simple structure, production and maintenance more convenient. 2. Small office by the valve stroke, opening and closing time is short. However, if make the disc into a ball or ceramic ball, the problem is solution of the struggle. 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.
