A deadweight safety valve for oil storage tank

The utility model provides a deadweight safety valve of oil storage tank. The deadweight safety valve is equipped with flange in its bottom, and the hydraulic oil import is equipped with to one side of outer barrel, and the barrel is cut apart to internal being equipped with of urceolus, and the valve gap is equipped with at the top of outer barrel, is equipped with the metering rod chi on the valve gap, and the metering rod chi stretches into to be cut apart in the barrel. The dismouting that the deadweight safety valve that prior art exists has been overcome to this deadweight safety valve exists filling volume and the liquid level unmanageable defect of potential safety hazard, hydraulic oil, safety valve structure is simple for this hydraulic pressure, and operation, maintenance are very convenient. 本实用新型提供了种储油罐的液压安全阀。所述液压安全阀在其底部装有连接法兰，外筒体的侧装有液压油进口，外筒体内装有分割筒体，外筒体的顶部装有阀盖，阀盖上装有量油尺，量油尺伸入到分割筒体内。该液压安全阀克服了现有技术存在的液压安全阀的拆装存在安全隐患、液压油的充装量和液面难以控制的缺陷；该液压安全阀结构简单，操作、维修十分方便。
