6-5 in two-way flow spinning ball valve general situation of the world's most sophisticated, the highest ratio of most of the valve ball valve pipe network system, mainly used for medium truncated and adjustment, this part of the valve in the system as a whole accounted for more than major, dosage, more durable, cost-effective for valve at the same time should be adjusted when medium positive flow and load break, while the differential transform or maintenance can prevent the backflow medium, which has a two-way cutting function. A few days ago, this part of the valve in the pipeline system, the main application of the cut-off valve, gate valve, butterfly valve and ball valve. Globe valve and gate valve, with good two-way cutting function, sealing performance and using life is pretty good, all the valve is one of the first, but stop valve door type structure of congenital restrictions, appearance is big operation torque, production of large diameter, the largest on the market at present only to DN400; Gate valve, no adjustment function to adjust flow exist gate off great dangers, and large-diameter gate also with its huge shape and height, the difficulties in the manufacturing and transportation. Compared with the butterfly valve and gate valve opening and closing time is short, the operating torque is small, light weight and small installation space features, such as part of the division of labor with butterfly valve gate Industrial Valves instead. However, has been the butterfly valve sealing performance has not fully meet the market requirements, in addition to the midline rubber lining can be two-way sealing butterfly Industrial Valves can to a certain pressure range, other basic for uniflow structure. The midline structures restricted by rubber can't popularity. Improved, appear on the market has both elastic piece structure of stainless steel butterfly valve, but its high cost. Mainly used in petroleum, natural gas, coal gas and other medium is relatively important line, in general network, especially water system application. 6-5 in two-way flow spinning ball valve main material a) Body: carbon steel, Except the goods indicated in the demand schedule) ; b) plate: stainless steel; c) Stem: stainless steel; d) Sealing surface: cobalt-based carbide surfacing. Technical requirements for a) Sediment abrasion resistance; b) The valve opening and closing flexible, not affected by medium pressure high and low; c) Seat and disc friction without opening and closing, have the close tight sealing; d) The valve plate sealing ring seal compensation function; 6-5 in two-way flow spinning ball valve technical parameters to smash two-way flow and ball contact medium for raw water, turbine oil, or insulating oil reservoir for worm gear eccentric structure flange ball valve, sealing type for the metal to metal seal, drive form for the worm gear and worm drive. Spin valve can be two-way flow, two-way sealing performance and can meet the requirements of nominal pressure. Confront the bidirectional flow spinning ball valve main type and working principle, main types: 1 the valve of the main types are: worm gear and worm, electric, pneumatic, hydraulic, pneumatic valve and hydraulic valve is suitable for places that have requirements of liquid pressure gas source and the source. 2, how it works: two-way flow is the main function of the valve can not only in positive pressure sealing good, when reverse pressure or reverse pressure is greater than positive pressure can also be properly sealed. When positive pressure, medium pressure push valve plate moving forward, deformation of the valve stem, valve plate seal face close to the valve seat sealing surface pressure, steps into the body seat, and good sealing. When reverse pressure, medium pressure push valve plate backward, deformation of the valve stem, medium pressure to push the seat backward at the same time, the valve seat sealing surface close to the valve plate seal face pressure, good seal. Two-way flow head spin ball valve, its main advantages: 1, not only can reliably shut off in positive pressure, the reverse pressure or reverse pressure is greater than the positive pressure can also reliably shut off; 2, on the sealing pair two seal can be used according to the different hardness of space plasma spraying, the etheric laser sputtering, vacuum protection permeability after welding and other advanced technology to form martensite stainless steel, austenitic stainless steel, hard alloy, functionally gradient materials such as metal ceramics, artificial diamond; 3, can automatically to align the center ( Adaptive) The wear and tear, and can automatically the distance compensation; 4, close make full use of the energy of the medium in the valve, automatic high sealing specific pressure, make the high hard seal deputy to achieve reliable zero leakage; 5, instantly shut down, no friction between instantly open the seal. When open the valve core projection section continuous condensed and back, opened the initial back faster than the inside shrink. Closing valve core projection section and expanding, closed initial inflation rate is greater than the forward rate, closed end of the forward rate is greater than the inflation rate. With eccentric and ball valve, cut-off valve, the characteristics of wedge gate valve; 6, the main body structure similar to butterfly valve, has the characteristics of the structure of the butterfly valve is short, small volume, thus can manufacture large diameter, super-large diameter, large caliber of the valve.
