The benefits of direct buried all welded ball pneumatic valve

why use pneumatic valve directly buried type all welded ball? Use of directly buried type pneumatic welding ball valve can solve many problems, its advantage is illustrated by the following to:
and heating network is often buried in order to control pneumatic valve need to be tall building pneumatic valve well, rain or snow will put the rubbish into the pneumatic valve well, these waste, can produce a large number of harmful gas in the borehole. Operators of the pneumatic valve pneumatic control valve well cause personnel injury. Burst pipe and pneumatic valve will cause harm to the operators.
, heating pipelines due to reasons such as construction, welding, corrosion pipeline often have sundry, medium flow will carry these debris flushing pneumatic valve sealing structure, pneumatic valve sealing surface damage to close the pneumatic valve is lax, close to snuff out valve becomes the decoration.
, ordinary pneumatic need to connect the valve and pipe flange, screw, gaskets, pneumatic valve and pipeline connection to waste a lot of material resources, is not conducive to the global environment and energy conservation and emissions reduction. For all welded directly buried type pneumatic valve to obtain the very good development.
