FIELD: valving engineering. ^ SUBSTANCE: valve comprises housing, seat, and plate that is movably connected with the axle and separates the housing space into the inlet and outlet spaces. The plate is secured to the seat between the lugs by means of the axle and is made in block with the seat. The seat with opening is locked inside the housing by means of a threaded bushing. Between the seat and housing is a sealing spacer. The housing is made of two parts with central coaxial openings. The parts of the housing are interconnected via a thread. Between the parts of the housing is a sealing spacer. The longitudinal axes of the openings in the housing and in the flanges are coincident. The longitudinal axis of the opening in the seat is inclined to the longitudinal axis of the housing and flanges. ^ EFFECT: enhanced pressure tightness and improved accessibility for repair. ^ 2 cl, 3 dwg |
