DEVICE pneumatically actuated valves for the thermal vacuum chamber inlet conduit SEALING HIGH-RISE stands for testing of turbojet

摘要

The invention relates to test equipment and can be used for high-rise test aircraft and missile technology. Apparatus pneumatically operated valves for sealing the inlet conduit thermal vacuum chamber altitude stand for testing jet engines, comprising Metal partition mounted between the outer and inner receivers supplying air in thermal vacuum chamber, a stationary flange cone having outer and inner flanges and is rigidly coupled to the outer flange with Metal partition, removable flange cone with outer and inner flanges with two sealing planes located on the outer m and internal flanges, and with an abutment surface formed on the surface of the outer flange opposite to the sealing plane disk partition with lateral coupling surfaces and a central hole, the inner surface of which is associated with the outer surface of the inlet conduit thermal vacuum chamber, and valves with a pneumatic actuator arranged uniformly circumferentially on a stationary flange cone able to cooperate with the bearing surface of the outer flange removable flantsevog a cone, wherein the pneumatic drive each shutter is formed as a double cavity of the cylinder and piston rod mounted on a stationary flange cone and the associated piston and rod cavities through the dispenser with the pressure source and the atmosphere, the piston rod of each piston is mechanically connected with one of the gates, a removable flanged outer cone flange sealing plane conjugate with the side surface of the inner flange of the stationary conical flange with a sealing element and sealing plane of the inner flange is associated with the side surface of the docking disk partitions. Cylinders pneumatic actuator valves are mounted on the inner flange of the stationary flange cone and provided with pneumatically spring-loaded retainers disposed in the cylinder for engagement with the piston rod in its extreme positions, the piston of each cylinder is made spring-loaded and is provided with a check valve for communicating the piston chamber of the cylinder with its rod cavity, each gate is designed as a stem end portion provided with a flattened, oriented to engage the support n overhnostyu outer flange removable flange cone cavity being pneumatically clamps constantly communicated with the hollow stem of a pneumatic drive cylinder valves channels made in the stock. Such embodiment a pneumatically actuated valves increases the reliability of operation of the device for sealing the inlet conduit thermal vacuum chamber altitude stand for testing jet engines.
