description FIELD: oil extractive industry. ^ SUBSTANCE: in accordance to first variant, valve contains body, locking element and rod with catching head, rigidly connected to locking element. In accordance to invention during extraction of oil from well, equipped with packer with shaft - hydraulic channel and locking element for closing this channel and shutting the well it is provided with container, mounted on locking element, in form of a barrel with open top, for collecting and accumulating mechanical admixtures, and perforated walls for flow of liquid. In accordance to second variant valve contains body and locking element. In accordance to invention during extraction of oil from well, equipped with packer with shaft - hydraulic channel and locking element for closure of this channel and stopping of well it is equipped with container, mounted on locking element, in form of barrel with open top, for collection and accumulation of mechanical admixtures, and perforated walls for passage of liquid. On internal side of container walls shelves and/or a recess are made. ^ EFFECT: prevented difficulties during replacement of well equipment. ^ 2 cl, 3 dwg
