5、密封材料耐老化、耐弱腐蚀，使用寿命长等特点。

进口手动法兰式蝶阀概述：

蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的阀门叫蝶阀。蝶阀全开到全关通常是小于900　，蝶阀和蝶杆本身没有自锁有力，为了蝶板的定位，要在阀杆上加装蜗轮减速器。采用蜗轮减速器，不仅可以使蝶板具有自锁能力，使蝶板停止在任意位置上，还能改善阀门的操作性能。工业蝶阀的特点能耐高温，适用压力范围也较高，阀门公称通径大，阀体采用碳钢制造，阀板的密封圈采用金属环代替橡胶环。大型高温蝶阀采用钢板焊接制造，主要用于高温介质的烟风道和煤气管道。

进口手动法兰式蝶阀优点：

启闭方便迅速、省力、流体阻力小，可以经常操作。

结构简单，体积小，重量轻。

可以运送泥浆，在管道口积存液体zui少。

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
