伞齿轮刀型闸阀安装尺寸以及外形图

伞齿轮刀型闸阀产品概述
伞齿轮刀型闸阀，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。超薄设计的伞齿轮刀型闸阀以其体积小、重量轻、阻流小、不积渣，易安装，易拆卸的优点彻底解决了普通闸阀、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伞齿轮刀型闸阀取代。
产品概述
伞齿轮刀型闸阀的齿形是圆弧形状，而且一般都是呈锥状，像伞形，故名伞齿轮。伞齿轮传动效率高，传动比稳定，圆弧重叠系数大，承载能力高，传动平稳平顺，工作可靠，结构紧凑，节能省料，节省空间，耐磨损，寿命长，噪音小。

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
Bevel gear knife gate valve tooth profile is arc shape, and are generally not cone shaped like a umbrella, therefore bevel gear. Bevel gear drive with high efficiency, stable transmission ratio, arc overlap coefficient is big, high bearing capacity, stable transmission smooth, reliable operation, compact structure, and energy saving material, saving space, wear resistance, long life and low noise.
