关于德国《LOCKE》洛克
德国LOCKE洛克国际集团有限公司成立于1875年,是一家流体制造商,主要服务于全球工业、以石油,天燃气,石化、蒸汽、水系统以及各类型流体控制系统,公司致力于产品设计、研发、制造、销售,为用户提供完善的流体控制方案和阀门制定方案。目前LOCKE在德国本土拥有3家阀门生产工厂,分别位于总部弗兰肯塔尔,佩格尼兹和侣能三地,并在中国设立全资加工厂,主要负责亚洲地区产品供应,在上海设立销售代理处,负责大陆运营及售后服务。
进口套筒式电动调节阀产品概述:
德国《LOCKE》洛克--进口套筒式电动调节阀采用阀塞和套筒导向,导向面大,故稳定性较好。LOCKE电动套筒调节阀常指双密封套筒阀,具有允许压差大、泄漏大的特点;也可以为单密封式套筒阀,具有泄漏小、允许压差小的特点,这种结构定货时予以特别说明。LOCKE电动套筒调节阀采用径向分布的多孔结构型式,则为低噪声套筒调节阀,这种结构不产生扭转式的振动,具有防振和耐磨的优点可降低噪声7dB以上;由于导向间隙小,对结晶、结巴、结垢介质和含纤维颗粒的不干净介质易堵卡。其适用场合与单座调节阀、双座调节阀完全一致。即单密封套筒阀用于泄漏要求较严、压差不大的干净介质场合,双密封套筒阀用于压差较大、泄漏要求不严的干净介质场合。
The sleeve type electric control valve imported from Locke adopts valve plug and sleeve guide, with large guide surface and good stability. Lock electric sleeve regulating valve usually refers to double sealed sleeve valve, which has the characteristics of large allowable pressure difference and large leakage; it can also be single sealed sleeve valve, with the characteristics of small leakage and small allowable pressure difference, which shall be specially explained when ordering. Locke electric sleeve control valve adopts radial distribution of porous structure, which is low noise sleeve control valve. This structure does not produce torsional vibration, has the advantages of anti vibration and wear resistance, and can reduce noise by more than 7dB. Due to small guide clearance, it is easy to block crystalline, stuttering, scaling media and unclean media containing fiber particles. It is suitable for single seat control valve and double seat control valve. That is to say, single seal sleeve valve is used for clean medium occasions with strict leakage requirements and small pressure difference, while double seal sleeve valve is used for clean medium occasions with large pressure difference and lax leakage requirements.
进口套筒式电动调节阀工作原理:
进口电动高压套筒调节阀,是电动单元组合仪表中的执行单元,它是生产过程自动调节系统中的重要环节之一,它以AC220V电源电压为动作力,接受统一标准信号0~10mA DC或4~20mA DC,将此转为与输入信号相对应的上下位移,自动地操纵阀门,改变阀门的开度位移,从而达到对工艺管路流体介质如压力,流量,温度,液位等参数的自动调节控制。
The imported electric high-voltage sleeve control valve is the executive unit of the electric unit combination instrument. It is one of the important links in the automatic control system of the production process. It takes AC220V power supply voltage as the action force, receives the unified standard signal of 0 ~ 10mA DC or 4 ~ 20mA DC, converts it into the up and down displacement corresponding to the input signal, and automatically operates the valve to change the opening displacement of the valve, So as to achieve the process of pipeline fluid medium such as pressure, flow, temperature, liquid level and other parameters of automatic adjustment and control.
