德国泰科螺纹球阀适用场所:
主要用于公称压力 PN 16~140、公称尺寸 DN 8~50低压、小口径管道上,用于截断水流和改变水流的分配或用于需快速启闭的场所。
德国泰科螺纹球阀特点:
1)流动阻力小;
2)结构简单;
3)体积小、重量轻;
4)目前球阀的密封面材料选用塑料,密封性好;
5)操作方便,开闭迅速,便于远距离的控制;
6)维修方便,密封圈一般都是活动的,拆卸更换方便;
7)全开或全闭时,球体和阀座的密封面与介质隔离,介质通过不会引起阀门密封面的侵蚀。
德国泰科螺纹球阀注意事项:
1)安装位置、高度、进出口方向必须符合设计要求,螺纹连接应牢固紧密。
2)安装在保温管道上的各类手动阀门,手柄均不得向下。
3)阀门安装前必须进行外观检查,阀门的铭牌应符合现在国家标准《通用阀门标志》GB 12220的规定。对于工作压力大于1.0 MPa 及在主干管道上起到切断作用的阀门,安装前应进行强度和密封试验,合格后方便使用。强度试验时,试验压力为公称压力的1.5倍,持续时间不少于5min,阀门壳体、填料应无渗漏为合格。密封试验时,试验压力为公称压力的1.1倍;试验压力的试验持续的时间应符合JB/T 9092标准要求,以阀瓣密封面无渗漏为合格。
4)阀门法兰与管线法兰间按管路设计要求装上密封垫。
5)带传动机构的球阀,按产品使用说明书的规定安装。

Application areas
Mainly for nominal pressure PN 16 ~ 140, nominal size DN 8 ~ 50 low, small-diameter pipe, used to truncate the distribution of water and change the flow or to require rapid opening and closing of the place.
Feature
1) flow resistance;
2) The structure is simple;
3) Small size, light weight;
4) valve sealing surface material selection plastic, sealing;
5) easy to operate, opening and closing rapidly, to facilitate remote control;
6) Easy maintenance, seals are generally activities, the removal easy to replace;
7) fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, the medium through the valve sealing surface will not cause erosion.
Precautions
A) the installation location, height, import and export orientation must meet the design requirements, should be firmly screwed tight.
2) installed in various types of pipe insulation manual valve handle shall not be down.
3) Valves must be visually inspected prior to installation, the valve plate should be consistent with national standards now "Universal Valve logo" GB 12220 requirements. For working pressure greater than 1.0 MPa and played off in the role of main pipeline valves should be carried out before installation and sealing strength test after passing the ease of use. Strength test, the test pressure is 1.5 times the nominal duration of not less than 5min, the valve casing, packing should be no leakage is qualified. Seal test, the test pressure is 1.1 times the nominal pressure; test pressure test duration should be consistent with JB / T 9092 standard requirements, the valve sealing surface without leakage is qualified.
4) between the valve flange and pipe flange installed on piping gasket design requirements.
5) with transmission valve, according to product instructions for the installation.
