刀型闸阀产品概述
刀型闸阀，又称刀闸阀或刀型浆闸阀。其应用范围非常广泛，从矿山、电厂的选煤、排矸、排渣，到城市的污水处理；从水泥、造纸厂的浆液输送，到食品、卫生、医药等专业管道。超薄设计的刀型闸阀以其体积小、重量轻、阻流小、不积渣，易安装，易拆卸的优点解决了普通闸阀、平板闸阀、球阀、截止阀、调节阀、蝶阀等阀门的阻流大，占空间，易积渣，不易安装和维修等疑难问题。因而大量的通用切断类阀和调节型阀门被刀型闸阀取代。
产品概述
手动对夹式刀型闸阀又叫手动插板阀或手动闸板阀，适用于糖浆、纸浆、污水、煤浆、灰渣、粉尘、渣水混合物等介质管道，可作为介质切断和节流使用，该刀型闸阀适合水平安装，亦倾斜安装。

Knife Gate Valve Product Introduction
Type knife gate valve, also known as the knife gate valve or knife gate valve type pulp. Its application scope is very broad, from coal mines, power plants, slag discharge, discharging the gangue, the city sewage treatment; From the cement slurry transportation, paper mills, to food, health, medicine and other professional pipeline. Ultra-thin design type knife gate valve with its small volume, light weight, small flow resistance, no slag, easy to install, easy to remove completely solve the advantages of the common gate valve, flat gate valve, ball valve, globe valve, regulating valve, butterfly valve, choke valve, occupy a space, easy slag deposition, not easy to install and maintenance problems. So a lot of general cut off valve and external regulation valve replaced by type knife gate valve.
Product Introduction
The valve is suatable for pipeline conveying such mediums including syrup,paper pulp,sludge,sewage,coal slurry,etc.for controlling switching on/off and throttling.it allows horizontal mounting as well as in clined mounting.
