以下是先导式溢流阀DB30A的产品中英文介绍：
中文介绍
DB30A先导式溢流阀是一种广泛应用于液压系统中的压力控制元件。它主要由先导阀和主阀组成，采用锥阀式结构。当系统压力超过导阀弹簧调定压力时，锥阀被打开，主阀芯上端的压力油通过阻尼器等部件流回，产生压差使主阀芯打开，从而实现压力油的溢流。该阀具有较高的工作压力，最高可达315bar，能够满足多种复杂工况的需求。其工作介质包括矿物油和磷酸酯，适用于丁腈橡胶或氟橡胶密封。此外，DB30A还具备多种连接方式，如板式、管式等，方便用户根据实际需求进行选择。它在起重运输、建筑机械、工程车间、机床、船舶、冶金等设备的液压系统中有着广泛的应用。
English Introduction
The DB30A pilot-operated relief valve is a pressure control element widely used in hydraulic systems. It mainly consists of a pilot valve and a main valve, both of which are of the conical valve structure. When the system pressure exceeds the pressure set by the pilot valve spring, the conical valve opens. The pressure oil at the upper end of the main valve core flows back through the orifice and other components, creating a pressure difference that opens the main valve core, thus achieving the overflow of pressure oil. This valve has a high working pressure, up to 315bar, which can meet the needs of various complex working conditions. Its working media include mineral oil and phosphate ester, suitable for nitrile rubber or fluororubber seals. Moreover, the DB30A has multiple connection methods, such as plate and pipe connections, which are convenient for users to choose according to their actual needs. It is widely used in hydraulic systems of equipment such as lifting and transportation machinery, construction machinery, engineering workshops, machine tools, ships, and metallurgy.
