刀型閘閥產(chǎn)品概述
刀型閘閥，又稱刀閘閥或刀型漿閘閥。其應(yīng)用范圍非常廣泛，從礦山、電廠的選煤、排矸、排渣，到城市的污水處理；從水泥、造紙廠的漿液輸送，到食品、衛(wèi)生、醫(yī)藥等專業(yè)管道。超薄設(shè)計的刀型閘閥以其體積小、重量輕、阻流小、不積渣，易安裝，易拆卸的優(yōu)點解決了普通閘閥、平板閘閥、球閥、截止閥、調(diào)節(jié)閥、蝶閥等閥門的阻流大，占空間，易積渣，不易安裝和維修等疑難問題。因而大量的通用切斷類閥和調(diào)節(jié)型閥門被刀型閘閥取代。
產(chǎn)品概述
手動對夾式刀型閘閥又叫手動插板閥或手動閘板閥，適用于糖漿、紙漿、污水、煤漿、灰渣、粉塵、渣水混合物等介質(zhì)管道，可作為介質(zhì)切斷和節(jié)流使用，該刀型閘閥適合水平安裝，亦傾斜安裝。

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.
