蝶阀是一种结构简单的调节阀,它的启闭部分是一个圆盘形蝶板,在阀体上绕自身轴线旋转,以达到启闭或调节的目的。蝶阀从全开到全关通常小于90。蝶阀和蝶阀杆不是自锁的。为了蝶板的定位,要在阀杆上安装蜗杆减速器。使用蜗轮蜗杆减速机不仅可以使蝶板在任意位置自动锁止蝶板,而且可以提高阀门的操作性能。上海良工阀门厂家具体为大家介绍关于蝶阀的运用知识。
Butterfly valve is a control valve with simple structure. Its opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis on the valve body to achieve the purpose of opening, closing or adjustment. The butterfly valve is usually less than 90 from fully open to fully closed. Butterfly valves and butterfly valve rods are not self-locking. For the positioning of the butterfly plate, a worm reducer shall be installed on the valve rod. The use of worm gear reducer can not only automatically lock the butterfly plate at any position, but also improve the operation performance of the valve. Shanghai Lianggong valve manufacturer introduces the application knowledge of butterfly valve.
1、具有良好的控制特性来自流量。蝶阀旋转90即可快速启闭,操作简单。因此,它被广泛应用于石油、化工、冶金、水电行业应用等诸多领域。
1. It has good control characteristics from flow. The butterfly valve can be opened and closed quickly by rotating 90, and the operation is simple. Therefore, it is widely used in petroleum, chemical industry, metallurgy, hydropower industry and many other fields.
2、随着密封技术的发展,蝶阀的密封圈技术也得到了进一步的提高。由于过去结构特性的限制,不适用于高温、高压、耐腐蚀、耐磨等行业的不足。高分子复合材料技术和方法取代传统方法,密封面层表面被耐高温、耐腐蚀的合金材料所取代。因此,行业专用蝶阀应用广泛。
2. With the development of sealing technology, the sealing ring technology of butterfly valve has been further improved. Due to the limitation of structural characteristics in the past, it is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries. Polymer composite technology and methods replace the traditional methods, and the surface of sealing surface layer is replaced by high temperature and corrosion-resistant alloy materials. Therefore, industry-specific butterfly valves are widely used.
3、一般在节流、节流控制和污泥介质中,结构长度短,启闭速度快(1/4转)。低压切断,蝶阀。
3. Generally, in throttling, throttling control and sludge medium, the structure length is short and the opening and closing speed is fast (1 / 4 turn). Low pressure cut-off, butterfly valve is recommended.
4、蝶阀适用于淡水、污水、海水、盐水、蒸汽、天然气、食品、医药、石油等要求完全密封、零气体泄漏试验、要求高寿命和工作温度之间的产品。-10度和150度各种酸、碱等管道。
4. Butterfly valves are suitable for products requiring complete sealing, zero gas leakage test, high service life and working temperature, such as fresh water, sewage, seawater, brine, steam, natural gas, food, medicine, petroleum, etc- Various acid, alkali and other pipelines at 10 degrees and 150 degrees.
5、蝶阀也可用于二位调节,通道变窄,噪音低,有气穴和放气现象,少量泄漏到大气和磨蚀性介质中。
5. The butterfly valve can also be used for two position regulation, with narrow channel, low noise, cavitation and deflation, and a small amount of leakage to the atmosphere and abrasive media.
以上是上海良工阀门厂家为大家介绍的关于蝶阀在实际应用中经常用到的场景。随着技术的发展,蝶阀产品的应用可能会越来越多。
The above is the scene often used in practical application of butterfly valve introduced by Shanghai Lianggong valve manufacturer. With the development of technology, the application of butterfly valve products may be more and more.
