Abstract

The invention discloses a hammer globe valve, belonging to the field of hydraulic equipments and comprising a valve body and a valve pocket; an inlet hole and an outlet hole arranged in a staggered way and communicated with the valve pocket are opened on the valve body; a lug boss is arranged on the inner wall of the valve pocket between the inlet hole and the outlet hole; a seal valve gasket is arranged corresponding to one side of the lug boss of the outlet hole and is arranged higher than the lug boss; valve cores are arranged in the valve pocket; the valve core corresponding to the inlet hole side is wrapped in a core retainer plate; the outer wall of the core retainer plate is in close contact with the inner wall of the valve pocket; one end of the core retainer plate is in contact with the seal valve gasket. The hammer globe valve has the advantages of convenient opening and closing, tight sealing, safe and reliable use and the like.

Description

technical field [0001] The invention relates to a hydraulic valve of a hydraulic system. Background technique [0002] The globe valve is a hydraulic component widely used in various hydraulic systems. In the high-pressure pipeline, due to the high oil pressure, a large force needs to be applied to it when opening or closing the globe valve, and the phenomenon of lax closure often occurs. . For example, the invention patent announced in the Chinese Patent Bulletin on November 24, 2004: Spinning globe valve, application number: 03 1 33323.0, consists of a valve body side transmission device, a pressure compensation device and a spinning device. The valve body side transmission device, The rear end of the transmission shaft is fixed on the bevel gear and meshes with the bevel gear installed on the front end of the driving gear shaft. The middle part of the driving gear shaft is equipped with an O-ring seal to cooperate with the gear box cover. The gasket on the driving gear ...
