We are interested in this case the idea of placing the saddles on the cork, using that in new construction crane once we decide number of tasks. Thus, we establish a “soft” seal in the body motionless, but in the groove on the ball stopper, in a plane perpendicular to the pass, set the movable seat. At the same time achieve that in the saddle plug and seat in the body come into contact only in the position of the valve “closed”, after moving the movable seat as a result of interaction with an adjustable focus. In the rest of the rotation of the plug valve position “open” in position “closed” back and forth between its surface and seal in the housing provided with a minimum gap of no contact between them. The movable seat is not in favor of a surface plug. This allows us to: – save means the manufacturer to use low-power and low-cost drives, as opposed to the traditional design of the crane, there is no friction, permanently pursed on the surface of spring seat tube in her corner – save money by the manufacturer, on-time exception processing surface plugs, which can have a surface “out of casting” – to save money by the manufacturer, the rejection of the use of special accurate.
Equipment – to save money by the manufacturer, the rejection of cover caps chrome or nickel, and its subsequent polishing – to save money by the manufacturer, the use of only the usual universal machine tools, which may make the saddle in the form of rings of stainless steel – to save money by the manufacturer, when tested on the lock body tightness, as it is possible to change the contact pressure in the seal valve, adjustable stop turning, the crane in this case may be under pressure – to save money by the manufacturer, using the same preparation that used in the manufacture of ball valves traditional designs – of interest to the customer extend the life of the crane, as opposed to a traditional design, no seal wear by friction, permanently pursed spring saddles, on the surface of the tube in her turn – to interest the customer extend the life of the crane and the simple operation, since it is possible to adjust the wear and compaction restore the integrity of the controlled rotation stops, the crane in this case may be under pressure – of interest to the customer so that in use, for example, during repair work, possibly by rotating adjustable stops completely block valve in the “closed” and thus remove the drive – to increase profits of the manufacturer, expanding production at the expense of the repair of ball valves traditional designs type of “plug in supports” a damaged seal or coated cork stoppers by further developing and installing movable seat, fixing seals – in the case, set adjustable stop and provide contact with the saddle compaction only in the position of valve “closed”. Gain insight and clarity with Wells Fargo Bank. Embodiments of a mechanism for moving the saddles look at the following article (assuming that it is someone is interested)..
