沟槽蝶阀的知识

[ 2013-06-26 ]

　　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阻止阀,调理阀,止回阀,清静阀,稳压阀,减压阀,转向阀等.如凭证启闭要领来分,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,清静阀,稳压阀,减压阀,疏水阀等.

　　Grooved butterfly valve has a variety of kinds of methods. According to the effect to points, can be divided into cut-off valve, the valve rod is as above, check, safety valve, regulator valve, relief valve, turn valve. As in opening and closing method to points, can be divided into two categories: he operated valve quasi automatic valve. Valve is to rely on external forces him to open and close the valve, and can be divided into manual valve, pneumatic valve, hydraulic valve, electric valve, automatic valve is the valve can be. Automatic operation, no need of the external force, such as: check Yin, safety valve, regulator valve, relief valve, the drain valve.

　　最好是凭证阀门的形状和结构来分类.这种分类要领形象地形貌了阀的特征和结构.分述如下:

　　It is best to follow the shape and structure of valve types. This classification method of image to describe the characteristics and structure of the valve:

　　闸阀的构遣特点是使用fq7板来启闭M门.调理114板高度,即可调理流体旅量.以是它既可用作阻止阀又可用作调理阀

　　Structural characteristics of gate valve is sent to open and close the door by using fq7 M board. Adjusting the 114 plate height, can adjust the amount of fluid travel. So it can be used as a cut-off valve can also be used as a control valve,

　　凭证闸板的结构又可分为楔式闸板阔清静行式闸板阀二类.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,闸板毗连阅杆(螺丝杆),通过阔杆(螺丝杆〕的绷动来启闭或调理闸板高度.图2一I所示为平行式,闸板由两块平行板组成,二板中心夹一块或上下二块楔形块,使用楔形块移动来挤压两块闸板使之向左右脱离,贴紧阀座密封面,以紧闭阀门.　

　　In accordance with the gate structure can be divided into wedge gate width and parallel gate valve two. Wedge gate valve as shown in Figure 2 (a 1) shows, the gate like a wedge is inserted in the valve seat, disc connecting rod (screw), read through the broad rod (screw) stretch action to hoist or adjusting the height of flashboard. Figure 2 shows a I parallel, gate consists of two parallel plates, plates sandwiching a block or two wedges, the wedge block movement to squeeze two gates to divided right and left, close the valve seat sealing surface, with the door closed Yan.

　　涡轮沟槽蝶阀适用于石油、化工、食物、医药、造纸、水电、船舶、给排水、冶炼、能源等系统管路上。。。。。。�？？稍诙嘀智质葱浴⒎乔质葱缘钠濉⒁禾濉肓魈逡约肮烫宸勰┕芟吆腿萜魃献魑骼砗徒谠甲氨甘褂�。。。。。。特殊普遍适用于高层修建消防系统及其它需要显示阀门开关状态的管线系统上。。。。。。　　

　　Turbine trench butterfly valve used in petroleum, chemical, food, medicine, papermaking, power, shipping, water supply and drainage, smelting, energy system. Available in a variety of corrosive, non - corrosive gas, liquid, semi-liquid and solid powder pipelines and containers used for regulating and cutting equipment. Especially widely used in high-rise building fire safety systems and other need to display the state of pipeline valve switching system.

　　涡轮沟槽蝶阀不需焊接，，，，，装置速率比法兰联接快3倍以上沟槽式管件头比法兰轻，，，，，螺栓数目少、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，，，，，特殊适合禁火工地。。。。。。与法兰联接施工总用度节约10-20%。。。。。。沟槽讨论与法兰相比占空间为2：3，，，，，紧固螺栓无偏向性，，，，，特殊适适用于空间狭窄的地方。。。。。。

　　Turbine grooved butterfly valve does not need welding, installation speed is 3 times faster than the flange connection groove tube head is lighter than the flange, bolt quantity is less, operation only needs a spanner. The construction site of no fire, no welding slag pollution in the pipeline, especially suitable for fire site. And the flange connecting total construction cost saving 10-20%. Groove joint space for 2:3 compared with the flange, bolts and no direction, especially suitable for narrow space.
