Abstract

The invention discloses a wedge-shaped door plank device. The wedge-shaped door plank device comprises a door plank wedge-shaped body, a wedge-shaped rail, an air cylinder, a frame, a frame wedge-shaped body, an adjustable limiting block, a sealing frame, a sealing gland and sealing padding. The frame serving as a main body is connected into a system. The air cylinder serving as a power source is fixed to the frame and connected to the door plank wedge-shaped body. The wedge-shaped rail is connected with the frame in a welding mode, and the frame wedge-shaped body, the wedge-shaped rail and the door plank wedge-shaped body are connected into a whole to form a channel sealing partition. The adjustable limiting block is fixed to the frame to adjust the wedge degree of the door plank wedge-shaped body to guarantee that the door plank wedge-shaped body cannot be clamped tightly through too large strength. The sealing frame is connected to the frame, and the sealing padding, the sealing gland and the sealing frame are combined to enable the door plank wedge-shaped body and the frame to be sealed. The wedge-shaped door plank device has the advantages of being simple and reasonable in structure, beneficial to machining, tight in sealing, safe and reliable.

Description

technical field [0001] The invention relates to a wedge-shaped door panel device, in particular, it is suitable for the plug-in panel door equipment that needs to be shut off and isolated in six parts of a thermal power plant. Background technique [0002] Among the six components of a thermal power plant, the sliding door used for shut-off isolation is used as the main isolation device. When the unit is put into operation, overhaul or standby, the sliding door must be opened and closed reliably and isolated safely. In addition, the working condition of the isolation door Because of high working temperature, large air duct cross-section, large stress, and high requirements for tightness and reliability of closing. [0003] After counting the defects of conventional sliding doors used in most occasions, there are mainly door panels that are not tightly closed, internal leakage, external leakage, the stroke of the locking cylinder is uncertain, and the door switch is not flexi...
