一、进口自力式铸钢调节阀概述
进口自力式铸钢调节阀(美国威盾VTON),Self cast steel control valve碳钢调节阀,也叫自力式铸钢控制阀,直接作用式铸钢调节阀,弹簧负载式调节阀,是指阀体采用采用优质碳钢阀体,不锈钢密封的调节阀,依靠流经阀内铸钢自身的压力、压差、温度作为能源驱动阀门自动工作,不需要外接电源和二次仪表,通过信号管传递到执行机构驱动阀瓣改变阀的开度,达到调节流体介质压力、流量、温度的目的阀门。
Self operated cast steel control valve (VTON, USA), also known as self operated cast steel control valve, direct acting cast steel control valve, spring loaded control valve, refers to a regulating valve with a high-quality carbon steel valve body and stainless steel seal. It relies on the pressure, pressure difference, and temperature of the cast steel flowing through the valve as the energy source to drive the valve to work automatically, without the need for external power supply and secondary instruments. It is transmitted through a signal pipe to the actuator to drive the valve disc to change the valve opening, achieving the purpose of regulating the pressure, flow rate, and temperature of the fluid medium.
二、进口自力式铸钢调节阀特征
1、节能环保,无需外加能源即能实现自动控制,有利于企业节约成本
2、阀门主体结构中,信号和推动的部件与主阀相互密封隔开,不会象其他控制方式那样因阀内部零件移损而出现滴、冒、漏现象。
3、把各控制要素如信号采测、放大、反馈、控制、执行集为一体,并在运行时巧妙地运用流体力学和气动原理,整个控制过程在一个阀体内全部完成,尽管结构不复杂,但十分可靠。
4、不需要用电和气等辅助能源,依靠管道内被控介质的自身压力进行控制,结构简单、安装方便、投资小运行成本低,特别适合在钢管密布或潮湿的环境中应用,而采用其他方式一般都需要用电或压缩空气作动力,系统结构相对复杂,给安装和使用带来很大不便,而且投入大、可靠性差。
