Abstract

The invention discloses a closed self-suction large-aperture quick-release valve, which comprises a valve body and a valve bonnet. A self-suction valve spool component is arranged in the valve body and comprises a valve spool with a through hole at the center, a plurality of oil holes which are communicated with the through hole are arranged on side walls of the valve spool, a valve spool rod is disposed in the through hole of the valve spool, one end of the valve spool rod is provided with an elastic component via a locking nut, the other end of the valve spool rod is connected with a valve spool moving cover, pre-tightening force is produced by the elastic component and is positioned on the valve spool by the valve spool moving cover via locking nuts at two ends of the valve spool rod , a valve spool inner cover is fixed above the valve spool rod in the valve spool, large-aperture holes A which match with an oil return pipe of an oil tank are arranged on side walls of the middle of the valve body, and an oil inlet hole, a blow-off hole and a large-aperture hole B matching with an oil cylinder are arranged on a side wall of the lower portion of the valve body. The closed self-suction large-aperture quick-release valve does not need to be provided with a high-power oil pump, so that energy consumption is greatly reduced, and noise is reduced.

Description

technical field [0001] The invention relates to a valve, in particular, it is a closed self-priming large-diameter valve on the large-tonnage special foaming molding machine oil cylinder for the production of shoe soles, foamed floor glue, heat preservation boards, luggage linings, diving clothing materials and other plastic or rubber products. Quick release valve. Background technique [0002] At present, it is known in the plastic or rubber product production industry that the large-tonnage special foam molding machines used to produce shoe soles, foamed floor glue, insulation boards, luggage linings, diving clothing materials, etc. must be configured to control Valves of corresponding specifications and sizes for oil in and out of the oil cylinder. The valve comprises a long cylindrical valve body, a valve cover is arranged on the upper end of the valve body, the valve cover has a central through hole, and a valve core and a sealing ring are arranged in the valve body. ...
