進(jìn)口手動(dòng)法蘭式蝶閥

德國(guó)巴赫進(jìn)口手動(dòng)法蘭式蝶閥特點(diǎn)：

1、設(shè)計(jì)新穎、合理、結(jié)構(gòu)*，重量輕，啟閉迅速。
2、操力矩小，操作方便，省力靈巧。
3、可以任何位置安裝，維修方便。
4、密封件可以更換，密封性能可靠達(dá)到雙向密封零泄漏。
5、密封材料耐老化、耐弱腐蝕，使用壽命長(zhǎng)等特點(diǎn)。

進(jìn)口手動(dòng)法蘭式蝶閥概述：

蝶閥啟閉件是一個(gè)圓盤(pán)形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的閥門(mén)叫蝶閥。蝶閥全開(kāi)到全關(guān)通常是小于900　，蝶閥和蝶桿本身沒(méi)有自鎖有力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門(mén)的操作性能。工業(yè)蝶閥的特點(diǎn)能耐高溫，適用壓力范圍也較高，閥門(mén)公稱通徑大，閥體采用碳鋼制造，閥板的密封圈采用金屬環(huán)代替橡膠環(huán)。大型高溫蝶閥采用鋼板焊接制造，主要用于高溫介質(zhì)的煙風(fēng)道和煤氣管道。

進(jìn)口手動(dòng)法蘭式蝶閥優(yōu)點(diǎn)：

啟閉方便迅速、省力、流體阻力小，可以經(jīng)常操作。

結(jié)構(gòu)簡(jiǎn)單，體積小，重量輕。

可以運(yùn)送泥漿，在管道口積存液體zui少。

低壓下，可以實(shí)現(xiàn)良好的密封。

調(diào)節(jié)性能好。

Import manual flange butterfly valve

Germany imported manual top flange type butterfly valve characteristics:

1, design novel, reasonable, unique structure, light weight, open and close quickly.

2, operating torque is small, easy to operate, labor-saving dexterity.

3, can be installed in any location, easy maintenance.

4, the seal can be replaced, the sealing performance to achieve two-way seal zero leakage.

5, sealing material aging, corrosion resistance, long life and other characteristics.

Import manual flange butterfly valve overview:

Butterfly valve opening and closing pieces is a disc shaped butterfly plate in the valve body around its own axis rotation, so as to achieve the opening or closing or regulating the valve called the butterfly valve. Butterfly valve is fully open to fully closed is usually less than 900, butterfly and butterfly stroke does not have strong self-locking, in order to position the disc to install the valve stem on the worm gear. The use of worm gear reducer, not only can make the butterfly plate with self-locking capability, so that the butterfly plate stops at any position, but also improve the operating performance of the valve. Industry specific characteristics of butterfly valves for high temperature, high pressure range, the valve nominal diameter of large, carbon steel valve body, the valve plate sealing ring with metal ring instead of rubber ring. Large scale high temperature butterfly valve is made of steel plate, which is mainly used for flue gas duct and gas pipeline in high temperature medium.

Import manual flange butterfly valve advantages:

Open and close quickly and easily, labor, fluid resistance is small, can often operate.

Simple structure, small size, light weight.

Can carry mud accumulation of fluid in the pipe outlet at least.

Low pressure, can achieve a good seal.

Good adjustment performance.

Technical parameters of imported manual flange butterfly valve:

Nominal diameter: 1/8 ~ 80 (DN1~DN2000);

5 pressure range: ASME/ANSI Class150 ~ CLASS2500 (PN2.5 ~ PN420)

6 working temperature: -196 ~980;

7 main applications: metallurgy, mining, chemical, petroleum, natural gas, petrochemical, power, heat, building and pharmaceutical industry
