Abstract

The invention discloses a sealing cover for a retarder, relates to a sealing cover, and aims to solve the problem that the conventional retarder equipment is used in an environment with severe working conditions, high use frequency and high load strength. In order to solve the problems that repair and maintenance are not in place in the using process, water enters an inner cavity of a retarder sliding oil cylinder assembly, icing occurs, hydraulic oil goes bad and increases, counter force of retarder equipment exceeds the limit in the working process, and potential safety hazards are brought to station yard shunting operation, the retarder device comprises a first sealing cover shell, a sealing gasket, a bottom plug, a one-way valve body and a valve spring. The bottom plug is installed at the bottom of the one-way valve installation hole, and the one-way valve body is arranged above the bottom plug and abuts against the sealing gasket. The sealing cover comprises a second sealing cover shell, a blasting diaphragm and a fixing sleeve. The second sealing cover shell is a cylinder, the blasting diaphragm is arranged at the bottom of the blasting diaphragm installation hole, and the fixing sleeve is installed at the position, above the blasting diaphragm, of the blasting diaphragm installation hole. The invention belongs to the field of railway dowty retarders.

Description

Technical field[0001]The present invention relates to a sealing cover, and more particularly to a sealing cover for decelerating the top.Background technique[0002]Top of the railway vehicle deceleration is a speed control device widely used in the formation of domestic and abroad. It does not require external energy to automatically control the speed of the vehicle, and can be installed in line segments, curve segments, and road channels in the tunnel. The reduction top speed system consists of deceleration capabilities of different functional features, which can not only improve the hump grouping capability, but also control the speed of the hump slippery, thereby realizing the safety of the vehicle, and greatly reducing the vehicle. Damaged accidents, realize the automation of the mosaic operation, and greatly improve the working conditions, get rid of artificial iron shoes, liberate the workers from the heavy dangeous labor conditions, completely eliminate personal injury acciden...
