FIELD: machine building. ^ SUBSTANCE: invention is related to valves manufacture and is intended for air exhaust from gas-containing structure. Plate valve design comprises ring-shaped frame element 3, installed on opening of gas-containing structure 2, round body element 4, installed with the possibility of removal on internal peripheral surface 4d of ring-shaped frame element 3, and valve 6, installed in space for installation of round body element 4 valve. Round body element 4 has obverse through hole 4e and inward through hole 4f. Valve 6 comprises sealing cap 6a and activating element 6b. Round body element 4 comprises ring-shaped groove 4b and rotating cap 5, subject to pressure by means of rotation. Obverse through hole 4e is shifted from center of ring-shaped groove 4b. Rotary cap 5 comprises hole 5b for gas forcing with extent of eccentricity identical to extent of eccentricity of obverse through hole 4e. ^ EFFECT: acceleration and facilitation of air exhaust and maintenance of air permeability of gas-containing structure and at provision of device functioning reliability. ^ 6 cl, 21 dwg |
