HYBRID BALL VALVE TRANSFORMER Russian patent published in 2016 - IPC F16K5/06 F16K27/06 

FIELD: construction.

SUBSTANCE: invention relates to pipeline valves and is designed as crane with rotary plug for regulation and termination of high-temperature working medium with solid inclusions. Hybrid ball valve-transformer includes housing with through hole, which is detachably connected with inlet and outlet pipes for connection with pipeline line. In said through hole there is rotating spindle ball plug, communicated with said branch pipes and coupled with moving and fixed circular metal seals. Inlet branch pipe is equipped with screw movement facility of movable ring seal. Spindle axis and screw are arranged at right angle to each other. Each of said branch pipes is attached to flange made on housing by means of its inner flange made on each branch pipe to allow crossing at angle α = 20-45° flange axis and axis of through hole in housing. Inner flange of each branch pipe and housing flange can transformation crane permutation pipes in accordance with distances between centers of connecting holes arranged on axes shifted in circle relative to centre of flange on angular pitch. Screw is located coaxially to above through hole and pivotally connected with perforated disc, at end of which is made above moving ring seal arranged in annular groove made in the inlet pipe, with possibility of axial movement of perforated disc at value facilitating free rotation of ball plug.

EFFECT: increased service life due to reduced wear of friction members by limiting ingress of abrasive substances and forces of plug and broader functional capabilities owing to changing configuration of crane.
