?進(jìn)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(jié)構(gòu)能使閥門達(dá)到零泄漏的效果，*的文丘里流線型流道設(shè)計(jì)具有流體阻力小、水擊壓力小、流態(tài)好、對(duì)介質(zhì)壓力變化響應(yīng)速度快、外形尺寸小等優(yōu)點(diǎn),是國內(nèi)外油氣集輸管網(wǎng)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.
