沟槽 蝶阀阀门的种类有多种分法.按其作用来分,可分为如上竿所述的 截止阀, 调节阀,止回阀,安全阀,稳压阀,减压阀,转向阀等.如按照启闭方法来分,可分为两大类:他动阀准自动阀.他动阀就是靠外来作用力来启闭的阀门,又可分为手动阀,气动阀,液压阀, 电动阀等.自动阀就是阀门可必自动操作,不需外力作用,例如: 止回阀,安全阀,稳压阀,减压阀,疏水阀等.

Grooved butterflyvalve hasa variety ofkinds ofmethods.According to the effectto points,can be divided intocut-off valve,thevalverodis as above,check,safety valve,regulator valve,relief valve,turnvalve.As inopening and closing methodto points,can be divided into two categories:heoperated valvequasiautomatic valve.Valveis to rely onexternalforceshimtoopen and close the valve,and can be divided intomanual valve,pneumatic valve,hydraulic valve,electricvalve,automaticvalveis the valvecanbe.Automatic operation,no need of the external force,such as:checkYin,safety valve,regulator valve,relief valve,the drain valve.

　　最好是按照阀门的形状和构造来分类.这种分类方法形象地描述了阀的特性和结构.分述如下:

It is best to follow theshape and structureof valvetypes.This classificationmethod ofimageto describe thecharacteristics andstructure ofthevalve:

闸阀的构遣特点是利用fq7板来启闭M门.调节114板高度,即可调节流体旅量.所以它既可用作截止阀又可用作调节阀

Structural characteristicsof gate valve issenttoopen and close thedoorby using fq7Mboard.Adjusting the 114plate height,can adjust theamount offluidtravel.So itcan be used as acut-off valvecan also be used as acontrol valve,

　　按照闸板的结构又可分为楔式闸板阔和平行式闸板阀二类.楔式闸板阀如图2一1(a)所示,闸板像一个楔子插在阀座上,闸板连接阅杆(螺丝杆),通过阔杆(螺丝杆〕的绷动来启闭或调节闸板高度.图2一I所示为平行式,闸板由两块平行板组成,二板中间夹一块或上下二块楔形块,利用楔形块移动来挤压两块闸板使之向左右分开,贴紧阀座密封面,以紧闭阀门.　

In accordance with thegate structurecan be divided intowedge gatewidthandparallel gate valvetwo.Wedge gate valveas shown in Figure2(a1)shows,the gatelikea wedgeis inserted in thevalve seat,disc connectingrod(screw),readthrough the broadrod(screw)stretchactiontohoistoradjusting the height of flashboard.Figure 2showsaIparallel,gateconsists of twoparallelplates,platessandwichingablockor twowedges,thewedge blockmovement tosqueezetwo gatestodivided right and left,closethe valve seat sealing surface,with thedoorclosedYan.

　　涡轮沟槽蝶阀适用于石油、化工、食品、医药、造纸、水电、船舶、给排水、冶炼、能源等系统管路上。可在多种腐蚀性、非腐蚀性的气体、液体、半流体以及固体粉末管线和容器上作为调节和节流设备使用。特别广泛适用于高层建筑消防系统及其它需要显示阀门开关状态的管线系统上。　　

Turbinetrenchbutterfly valve used in petroleum,chemical,food,medicine,papermaking,power,shipping,water supply and drainage,smelting,energysystem.Available in a variety of corrosive,non -corrosive gas,liquid,semi-liquidand solid powder pipelines and containersused for regulating and cutting equipment.Especially widely used inhigh-rise building fire safety systems and otherneed to displaythe state of pipeline valve switching system.

　　涡轮沟槽蝶阀不需焊接，安装速度比法兰联接快3倍以上沟槽式管件头比法兰轻，螺栓数量少、作业仅需一把板手即可。施工现场不动火，管路内无焊接渣污染，特别适合禁火工地。与法兰联接施工总费用节约10-20%。沟槽接头与法兰相比占空间为2：3，紧固螺栓无方向性，特别适合用于空间狭小的地方。
