进口插板阀原理特点
进口插板阀是一种闸板与阀座始终紧密接触密封的阀门,其原理是闸板上开有一个通径大小的圆口,通过闸板启闭使得闸板上圆口跟通径做完全脱离和相吻合的动作,广泛使用在冶金、矿山、建材、粮食等行业。
The TK model knife gate is a bi-directional wafer valve designed for media with high consistency. The double seat design assures a non-clogging shut off on either normal or reverse flow. The valve is used in a wide range of demanding applications in industries such as:
• Pulp & Paper
• Wastewater Treatment Plants
• Chemical plants
• Power Plants
• Etc.
