FIELD: mechanical engineering.
SUBSTANCE: invention relates to design of pipeline valving for cutting off medium flows in different technological pipelines. Proposed gate of pipeline fitting contains sealing rings with interacting sealing fields. Sealing rings are secured on shutoff member and on housing by means of half-rings. Sealing rings are made detachable, being provided with two side plane-parallel sealing fields, and are sealed relative to shutoff member and housing.
EFFECT: increased overhaul period of gate owing to turning over of sealing rings with two side sealing fields and fastening of sealing rings by half-rings.
