RETZ瑞茨『進口軸流式止回閥』詳細介紹●RETZ止回閥系列●RETZ軸流式止回閥●產品數據
?進口軸流式止回閥描述--
RETZ軸流式止回閥具有一般止回閥的止回功能，又有雙重密封閥座結構能使閥門達到零泄漏的效果，*的文丘里流線型流道設計具有流體阻力小、水擊壓力小、流態(tài)好、對介質壓力變化響應速度快、外形尺寸小等優(yōu)點,是國內外油氣集輸管網系統(tǒng)特別是輸油泵出口的優(yōu)選閥門。
RETZ axial flow check valve has the check function of the general check valve and the double sealing seat structure can make the valve achieve the effect of zero leakage. The unique Venturi streamline flow channel design has the advantages of small fluid resistance, small water hammer pressure, good flow state, fast response to medium pressure change, small shape and so on. Oil and gas gathering and transportation network system, especially the preferred valve for the outlet of the oil pump.
