溝槽蝶閥閥門的種類有多種分法.按其作用來(lái)分,可分為如上竿所述的截止閥,調(diào)節(jié)閥,止回閥,安全閥,穩(wěn)壓閥,減壓閥,轉(zhuǎn)向閥等.如按照啟閉方法來(lái)分,可分為兩大類:他動(dòng)閥準(zhǔn)自動(dòng)閥.他動(dòng)閥就是靠外來(lái)作用力來(lái)啟閉的閥門,又可分為手動(dòng)閥,氣動(dòng)閥,液壓閥,電動(dòng)閥等.自動(dòng)閥就是閥門可必自動(dòng)操作,不需外力作用,例如:止回閥,安全閥,穩(wěn)壓閥,減壓閥,疏水閥等.

　　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.

　　最好是按照閥門的形狀和構(gòu)造來(lái)分類.這種分類方法形象地描述了閥的特性和結(jié)構(gòu).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:

　　閘閥的構(gòu)遣特點(diǎn)是利用fq7板來(lái)啟閉M門.調(diào)節(jié)114板高度,即可調(diào)節(jié)流體旅量.所以它既可用作截止閥又可用作調(diào)節(jié)閥

　　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,

　　按照閘板的結(jié)構(gòu)又可分為楔式閘板闊和平行式閘板閥二類.楔式閘板閥如圖2一1(a)所示,閘板像一個(gè)楔子插在閥座上,閘板連接閱桿(螺絲桿),通過(guò)闊桿(螺絲桿〕的繃動(dòng)來(lái)啟閉或調(diào)節(jié)閘板高度.圖2一I所示為平行式,閘板由兩塊平行板組成,二板中間夾一塊或上下二塊楔形塊,利用楔形塊移動(dòng)來(lái)擠壓兩塊閘板使之向左右分開,貼緊閥座密封面,以緊閉閥門.　

　　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.

　　渦輪溝槽蝶閥適用于石油、化工、食品、醫(yī)藥、造紙、水電、船舶、給排水、冶煉、能源等系統(tǒng)管路上。可在多種腐蝕性、非腐蝕性的氣體、液體、半流體以及固體粉末管線和容器上作為調(diào)節(jié)和節(jié)流設(shè)備使用。特別廣泛適用于高層建筑消防系統(tǒng)及其它需要顯示閥門開關(guān)狀態(tài)的管線系統(tǒng)上?！　?br />

　　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.

　　渦輪溝槽蝶閥不需焊接，安裝速度比法蘭聯(lián)接快3倍以上溝槽式管件頭比法蘭輕，螺栓數(shù)量少、作業(yè)僅需一把板手即可。施工現(xiàn)場(chǎng)不動(dòng)火，管路內(nèi)無(wú)焊接渣污染，特別適合禁火工地。與法蘭聯(lián)接施工總費(fèi)用節(jié)約10-20%。溝槽接頭與法蘭相比占空間為2：3，緊固螺栓無(wú)方向性，特別適合用于空間狹小的地方。

　　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.
