金沙js5官网在线厂家分享高压针阀使用注意事项

发布时间:2020-04-30 10:53:18   发布人:
  高压针阀是一种具有高耐压性能和小通径的高压截止阀。
  High pressure needle valve is a kind of high pressure stop valve with high pressure resistance and small diameter.
  1.在安装高压针阀之前,检查针阀的形状是否有损坏。如果有任何损坏,针形阀不能正常使用。
  1. Before installing the high-pressure needle valve, check whether the shape of the needle valve is damaged. If there is any damage, the needle valve will not work properly.
  2.安装前,检查阀门是否接口,阀门内部和阀门表面干净,如果不干净,可以使用一个气枪清洗(注:如果有废铁,一定要把废铁和其他固体颗粒,然后清洗,以免伤害身体内部甚至密封面)。

  2. Before installation, check whether the valve interface, the inside of the valve and the valve surface are clean. If they are not clean, use an air gun to clean them (Note: if there is scrap iron, be sure to clean the scrap iron and other solid particles, and then clean them, so as not to hurt the inside of the body or even the sealing surface).
  3.根据针阀结构,将针阀正确安装在管道或系统上。对于标记在进口和出口的针形阀,使用进口进口出口。对于没有标识针阀的进出口,按低进高接的原则,即在低接是进口,在高接是出口。注意,管道和系统也必须是干净的,应该在系统中安装过滤器以保护系统组件。
  3. Install the needle valve on the pipeline or system correctly according to the structure of the needle valve. For needle valves marked at inlet and outlet, use inlet inlet outlet. For the inlet and outlet of needle valve without identification, the principle of low inlet and high connection shall be followed, that is, the low connection is the inlet and the high connection is the outlet. Note that piping and systems must also be clean and filters should be installed in the system to protect system components.
  4.安装完成后,启动/关闭针形阀2-3次,检查其性能。注意,在开启或关闭阀门时,不要太用力(太用力可能导致密封失效)。一般情况下,当大家关闭阀门时,只要大家能够关闭并承受系统压力就不能强转动手柄。
  4. After installation, start / close the needle valve 2-3 times and check its performance. Note that when opening or closing the valve, do not use too much force (too much force may cause seal failure). In general, when we close the valve, as long as we can close and bear the system pressure, we can not force the handle to rotate.
