Abstract

The invention discloses a clamp for a cleaning cavity of an air brake control valve middle body. The clamp comprises a cleaning chamber shell and a cleaning chamber formed in the cleaning chamber shell, wherein a foundation is arranged at the bottom of the cleaning chamber; a placing hole corresponding to a bolt on the air brake control valve middle body is formed in the foundation; side hydraulic oil cylinders and a top hydraulic oil cylinder are respectively arranged on the left side, the right side and the top of the cleaning chamber shell; side sealing covers and a top sealing cover are respectively arranged at one end of piston rods of each of the side hydraulic oil cylinders and the top hydraulic oil cylinder; a reset spring is arranged on each of the side sealing covers and the top sealing cover; a conical positioning hole is formed in each of the side sealing covers and the top sealing cover. The clamp has the advantages of simple structure and convenience in operation, is capable of eliminating size error, and satisfies the cleaning requirement of middle bodies from different factories, the sealing property is stable, and a clamping process is simple, quick and safe.

Description

technical field [0001] The invention relates to a jig for cleaning the internal cavity of an air brake control valve intermediate, and belongs to the technical field of cleaning the internal cavity of a railway vehicle air valve valve. Background technique [0002] At present, the air brake control valve (120 valve) for railway freight cars is the control center and core component of the freight car brake. The production and maintenance quality of the 120 valve directly affects the safety of railway operation. There are also many accessories, many air passages and the aperture is small, the smallest diameter is only ∮0.2mm, so if the dirt, sludge and other sundries formed during the production and use of the valve are not completely removed, it is easy to block the brake. The air channel causes brake failure and brings serious hidden dangers to the safety of railway wagons. The existing cleaning method is to place the air brake control valve in a special cleaning device and ...
