涡轮偏心半球阀
Turbine eccentric half ball valve
产品概述
偏心半球阀是一种比较新型的球阀类别，它有着自身结构所独有的一些优越性，如开关无摩擦，密封不易磨损，启闭力矩小。这样可减小所配执行器的规格。配以多回转电动执行机构，可实现对介质的调节和严密切断。
Product Overview
Eccentric half ball valve is a relatively new type of ball valve category, it has its own structure has some unique advantages, such as no friction switch, seal is not easy to wear, small opening and closing torque. This reduces the size of the configured actuator. With a multi-turn electric actuator, the medium can be adjusted and tightly cut off.
特点
①解决了工业生产中的浆状、混流液体、灰尘等介质在管道输送中沉淀、易结垢、阻塞，使阀门关不严等问题。
②开关轻便，开启时球与壳体脱离，无任何接触，启动扭矩小，转动灵活。关闭时，半球与阀座的挤切作用能除去密封面上的污物，使阀门顺利启闭，安全系数高，密封性能好。
③密封面的偏心结构，使球面能自动补偿磨损，能保持阀门的密封，使用寿命长。
④该阀门T型是属于耐磨硬密封球阀，它的密封副材料是特殊的，密封面要经过特殊耐磨处理。处理后表面硬度可达到HRC65-72度，故阀门的耐磨性能特别好。⑤阀门表面油漆，有常温和高温两种。高温用耐温600℃的进口漆，喷涂后，高温使用不烧漆、炭化、焦化现象、不变色。
peculiarity
① Solve the problem that slurry, mixed flow liquid, dust and other media in industrial production precipitate, easy to scale and block in pipeline transportation, so that the valve is not tightly closed.
② The switch is light, the ball is separated from the shell when it is opened, without any contact, the starting torque is small, and the rotation is flexible. When closed, the squeezing and cutting action between the hemisphere and the seat can remove the dirt on the sealing surface, so that the valve can be opened and closed smoothly, with high safety factor and good sealing performance.
The eccentric structure of the sealing surface enables the sphere to automatically compensate for wear, maintain the seal of the valve, and have a long service life.
④ The valve T-type is a wear-resistant hard seal ball valve, and its sealing auxiliary material
It is special, and the sealing surface should be treated with special wear resistance. The surface hardness after treatment can reach HRC65-72 degrees, so the wear resistance of the valve is particularly good. ⑤ Valve surface paint, there are room temperature and high temperature two. High-temperature imported paint with a temperature resistance of 600℃, after spraying, high-temperature use of no paint, carbonization, coking phenomenon, no discoloration.
