RETZ/我們一直致力于流體控制和測控領域的持續創新,始于2005……(開關型,調節型)進口電動法蘭球閥是由電動執行器與高性能球閥組成。適用于兩位切斷、調節的場合 (Cast steel, stainless steel) imported electric flange ball valve is composed of electric actuator and high-performance ball valve. Applicable to two-position cut-off and adjustment occasions
根據結構形式可分為:電動軟密封球閥和電動硬密封球閥兩類。軟密封球閥主要適用于溫度低于250度以內的介質。硬密封球閥主要適用于250度以上的介質 According to the structure, it can be divided into two types: electric soft seal ball valve and electric hard seal ball valve. Soft seal ball valve is mainly applicable to the medium with temperature below 250 ℃. Hard seal ball valve is mainly applicable to medium above 250 ℃
電動法蘭球閥密封性能優良、流通能力大、裝卸維護方便、流阻小、密封可靠,甚至切斷。電動法蘭球閥體積小、重量輕、推力大、功能強、伺服放大器內裝、操作方便、可靠性高,球閥與執行器采用直連方式,內置伺服系統,無須另配伺服放大器,輸入輸出信號4-20mA及220VAC電源即可控制運轉。電動法蘭球閥具有連線簡單、結構緊湊、動作穩定可靠等優點 The electric flanged ball valve has excellent sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing and even cut-off. Electric flanged ball valve has small size, light weight, large thrust, strong function, built-in servo amplifier, convenient operation and high reliability. The ball valve and actuator are directly connected, with built-in servo system, without additional servo amplifier. The input and output signals can be controlled by 4-20mA and 220VAC power supply. Electric flange ball valve has the advantages of simple connection, compact structure, stable and reliable action, etc
產品特點 Product features
(1)流體阻力小,即使是縮徑球閥,其流體阻力也相當小 The fluid resistance is small, even for the reduced diameter ball valve, its fluid resistance is also quite small
(2)止推軸承減小閥桿摩擦力矩,可使閥桿長期操作平衡靈活 The thrust bearing reduces the friction torque of the valve rod, which can make the valve rod balance and flexible for long-term operation
(3)閥座密封性能好,采用聚四氟乙烯等材料制成的密封圈,結構易于密封,而且球閥的閥封能力隨著介質壓力的增設而增大 The sealing performance of the valve seat is good. The sealing ring made of polytetrafluoroethylene and other materials is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure
(4)閥桿密封可靠,由于閥桿只作旋轉運動而不做升降運動,閥桿的填料密封不易破壞,且密封能力隨著介質的壓力增設而增大 The valve rod is sealed reliably. Because the valve rod only rotates without lifting, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure
(5)由于聚四氟乙烯等材料具有良好的自潤滑性,與球體的摩擦損失小,幫球閥的使用壽命長 Due to the good self-lubrication of PTFE and other materials, the friction loss with the ball is small, and the service life of the ball valve is long
(6)下裝式閥桿和閥桿頭部凸階防止閥桿噴出,如火災造成閥桿密封破壞,凸階與閥體間還可形成金屬接觸,確保閥桿密封 The bottom-mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying out. If the valve stem seal is damaged by fire, the metal contact between the convex step and the valve body can also be formed to ensure the valve stem seal
