特點 | Characteristic |
該閥系高性能球狀高壓控制閥。其主要特點是:因閥瓣為球狀 ,在很小的比壓下就能實現密封。由于閥座表面經特殊處理, 所以具有耐高溫、耐沖刺、耐氣蝕、使用壽命長、扭矩小、開 關靈活、密封可靠等優點,克服了通用針型閥的一系列缺點, 是目前的控制閥門。 | This valve is that spherical high pressure of high performance controls the valve. Its main characteristicis: Because the valve one is spherical, the very small in can be realized sealing than under pressing. Through special-purpose processing, so have high temperature of able to bearing, is it erode, able to bear vapour lose, have long performance life, torsion little, flexible because of valve flat surface sealing advantaging such as being reliable switch to able to bear, having overcome aseries of shortcomings of the needle type valvein common use, is the most ideal control valve at present. |
