美国BOLON软密封对夹式凸耳蝶阀概述:
美标硬密封对夹式凸耳蝶阀又名支耳式蝶阀、单夹式蝶阀,是用双头螺栓将阀门连接在两管道法兰之间。美标硬密封对夹式凸耳蝶阀是用圆形蝶板作启闭件并随阀杆转动来开启、关闭和调节流体通道的一种阀门。美标硬密封对夹式凸耳蝶阀适用于给消防管道、排水、污水、食品、供暖、燃气、船舶、水电、冶金、能源系统以及轻纺等行业。
美标硬密封对夹式凸耳蝶阀编号815、830系列蝶阀的主要结构特征为对夹式和法兰式三偏心结构,而815、830L系列蝶阀的主要结构特征为阀体周边带凸耳且设计成带螺孔单法兰结构。815、830系列蝶阀广泛应用于石油、化工及工业环保水处理、高层建筑、给排水等管道上。其特点为:由于采用的是三偏心结构,密闭性能可靠,确保开启时蝶板不接触密封座,消除了密封座不均匀负载,延长了使用寿命、确保可靠的密封性能,具有耐高温、耐磨损、耐腐蚀等优点。
美国BOLON软密封对夹式凸耳蝶阀原理:
美国BOLON软封对夹式凸耳蝶阀是圆盘阀瓣,围绕阀轴旋转来达到开启与关闭的一种阀,在管道上主要起切断和节流用。启闭件是一个圆盘形的蝶板,在阀体内绕其自身的轴线旋转,从而达到启闭或调节的目的。蝶阀全开到全关通常是小于90°。

The United States of America BOLON soft sealing clamp lug butterfly valve overview: American standard hard sealing clamp lug butterfly valve also known as supporting ear butterfly, single wafer type butterfly valve, is double-headed bolts to connect the valve between the two pipe flanges. American standard hard sealing clamp lug circular disc butterfly valve is used for opening and closing parts and a valve to open, close and adjust the fluid channel with the valve stem rotation. American standard hard sealing clamp lug butterfly valve is suitable for the fire pipes, drainage, sewage, food, heating, gas, power, metallurgy, shipbuilding, energy systems and textile industries. American standard hard seal structure characteristics of the clamp lug butterfly valve No. 815, 830 series of butterfly valve is on the clip and flange type three eccentric structure, and the main characteristics of the 815, 830L Series Butterfly Valves for valve surrounding belt lug design with screw and single flange structure. 815, 830 series of butterfly valve is widely used in petroleum, chemical and industrial water treatment, high-rise buildings, water supply and drainage pipeline. Its characteristics are: due to the use of the three eccentric structure, sealed reliable performance, ensure open butterfly plate does not contact the sealing seat, the seat is not uniform load, prolongs the service life, ensure reliable sealing performance, has the advantages of high temperature resistance, wear resistance, corrosion resistance. The United States of America BOLON soft sealing clamp lug butterfly valve principle: The United States of America BOLON soft sealing clamp lug butterfly valve is the valve disk, around the valve axis to achieve the opening and closing a valve in the pipe, and cut off from the main throttle with. Headstock piece is a disc-shaped butterfly plate in the valve body, rotating around its own axis, so as to achieve the purpose of regulating the opening and closing or. Valve fully open to fully closed is usually less than 90 °. Lug butterfly valve technology parameters: Nominal pressure: 150Lb-300Lb;
