DRENCHER HEAD Russian patent published in 2014 - IPC A62C31/02 

FIELD: process engineering.

SUBSTANCE: drencher head comprises casing with sprayer mounted thereat and composed by the body made up of threaded union with through bore. Said threaded part is engaged with end circular bead accommodating shutoff valve. Two curved stiffness ribs connected with sprayer are coupled with said end circular bead. Note here that the diameter of circular bead surface whereto connected are two ends of said stiffness ribs is at least three times larger than that of sprayer surface. Two opposite ends of stiffness ribs are connected to sprayer surface. Said sprayer is composed of a socket making a portion of spherical surface confined by inner and outer hemispheres. Note that hemisphere centre is located at the line connecting threaded union through bore axis with valve axis. Three grooves are made at socket outer side their axes being located at hemisphere radial lines. Note also that hemisphere peripheral part has at least two orifices arranged in circle with centres located in the plane parallel with hemisphere centre line perpendicular to that connecting the threaded union through bore axis with valve axis. At least three orifices are located at every row.

EFFECT: perfected design.
