摘要
阐述了电动防爆V形球阀的结构和工作原理,分析了其流量特性及影响因素,提出了防爆设计关键问题,对V形球阀的传统结构设计进行了大的改进,使新设计的V形球阀具有调节精度高、安全防爆、密封可靠、驱动力矩小、使用寿命长的优点。
This paper describes the structure composition and operation of the electric explosion- proof V-ball valve, analyses the characteristics of flow rate and the influence factors, and discusses the principle and key point of explosion-proof design. The traditional structure of the valve is greatly improved so that the new kind of V-ball valve has the following advantages : high precision of adjustment, good safety of explosion-proof, reliable sealing, low driving torque and long life of use.
