Problems solved by technology

[0005] There is a problem that the unit price of the valve itself increases due to the addition of such parts and the precision machining to form the flow path of the safety valve.
In addition, there are difficulties in the quality control of the addition of parts and the flow path that has been precisely processed.

Abstract

The invention relates to a safety valve which pressurizes an elastic component in a housing based an oil pressure for regulating a release pressure. The safety valve comprises the components of a plunger which is elastically supported by the elastic component and is internally provided with a main plunger flow path in a manner that oil that flows into the housing can move; an adjusting stopper which is hollow at the inner part and is arranged at one side of the housing; and a piston which is configured in a manner that the inner circumferential surface faces the outer circumferential surface of one area of the plunger. One area of the outer circumferential surface divides the inner part of the adjusting stopper into a first chamber and a second chamber, and moves through the oil pressure or the elastic component.

Description

technical field [0001] The present invention relates to a safety valve, and more specifically, to a safety valve in which a release pressure is adjusted by pressurizing an elastic member based on oil pressure inside a casing. Background technique [0002] In general, a safety valve performs a role of selectively communicating a flow path based on a set pressure. The safety valve pressurizes the spring through the flow path formed inside by the pressure of the oil flowing into the inlet, and communicates the inlet and the outlet based on the set pressure so that the flow path connected to the safety valve communicates. [0003] Such a safety valve may be provided in a hydraulically driven device and controlled to prevent the pressure in the hydraulic circuit from rising above a set pressure. [0004] Conventional safety valves have a problem in that their interiors are formed to have complicated flow paths. In this case, the accuracy of parts is required, and a precise proc...
