All welded ball buried type and working principle of the pneumatic valve characteristics

a: buried all welded ball type pneumatic valve working principle:
buried type pneumatic valve ball can be directly buried underground, need not build high large pneumatic valve well, only need to set up small shallow Wells on the ground, greatly reduce the construction cost and project time. Can be adjusted according to the requirements of the pipeline construction and design, the length of the pneumatic valve and the height of the pneumatic valve stem. Sphere of machining accuracy is very precise and convenient operation, no harmful interference. Compared with similar industry of the same specification products, pneumatic valve body is small, and beautiful. And can prevent the risk of gas explosion, buried type ball pneumatic valve pneumatic valve is very safe. Buried type pneumatic valve ball drive, the operator does not need to enter the underground, simply on the ground for transmission operation, very safe and convenient.
2: all welded ball buried type pneumatic valve features:
buried all welded ball design characteristics of the pneumatic valve is integral whole welding, such as diameter and variable diameter channel, the fixed and floating ball, double piston effect sealing system, pneumatic valve stem, long pneumatic valve body, short pneumatic valve stem, long pneumatic valve body, directly buried type.
: as the buried all welded type pneumatic valve pneumatic ball valve body is welded structure, so the pneumatic valve light weight and easy for insulation
: spring loaded type sealing to ensure in all applications of PTFE sphere under the condition of absolute rigor
: all welded ball buried type pneumatic valve ball and stem are made by stainless steel with two o-rings shot out pneumatic valve stem structure, this kind of pneumatic valve stem fly prevention structure is: set up the steps, at the bottom of the pneumatic valve stem bottoms pneumatic valve stem from inside the pneumatic valve body, preventing pneumatic valve stem. Ensure its rigor, the upper container can be replaced, long working life.
: buried type pneumatic welding ball valve has a welding wire,
and the flange connection: get ISO certification
: steel ball pneumatic valve is suitable for the local heating and cooling systems, such as pressure pipelines of oil and gas pipe.
: anti-static function: between the spheres and pneumatic valve body or pneumatic valve stem the Settings of the anti-static spring, will be generated switch movement process of electrostatic export.
