(換向)氣動三通高壓球閥用來截斷工作介質(zhì)和使工作介質(zhì)的液流換向,球閥不是設(shè)計為流量控制制閥,因此要么全開要么全閉以免損壞密封(Reversing) The imported pneumatic three-way high-pressure ball valve is usedto cut off the working medium and reverse the liquid flow of the working medium.The ball valve is not designed as a flow control valve, so it is either fullyopen or fully closed to avoid damaging the seal
進口氣動三通高壓球閥產(chǎn)品詳情Product details
氣動三通高壓球閥閥芯為L形結(jié)構(gòu),轉(zhuǎn)向過程中三個接口互相連接,旋轉(zhuǎn)控制芯軸使液體按球口形狀換向,同時無泄漏地截斷對進口三通高壓球閥2.jpg立的一側(cè),系統(tǒng)壓力把球體推向密封的無壓側(cè)。球體無泄漏地截斷從接口1到接口2或3的液流。當(dāng)流向從接口2或3到接口1時,會有少許泄漏,但取決于壓力 RETZ(Reversing) The inlet three-way high-pressure ball valve core is L-shapedstructure. During the steering process, the three interfaces are connected witheach other. Rotate the control spindle to make the liquid reverse according tothe shape of the ball mouth. At the same time, cut off the opposite sidewithout leakage. The system pressure pushes the ball toward the non pressureside of the seal. The ball can cut off the liquid flow from interface 1 to interface2 or 3 without leakage. When the flow direction is from interface 2 or 3 tointerface 1, there will be a little leakage, but it depends on the pressure
