Use the underground buried type all welded ball the advantage of pneumatic valve

use the advantage of directly buried underground type pneumatic valve ball:
the inside of the modern urban vehicles and pedestrians, roads is also very complex. So in the construction and maintenance of gas supply and heating supply line to the construction time and construction safety requirement is very high. Adopts full welding pneumatic ball valve, can be directly buried deep underground. Using the latest engineering construction method can maximize reduce pneumatic valve control of space, and greatly reduce the construction cost and project time. And can prevent the risk of gas explosion, the whole welding pneumatic ball valve pneumatic valve is very safe. Directly 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.
all welded directly buried underground type pneumatic valve ball there will be no external leakage phenomenon, such as the pneumatic seat is made of carbide, fluorine, sealing ring and cafe spring, in order to adapt to the change of pressure and temperature capability is strong, with pressure and temperature range will not produce any drainage and smooth. Sphere of track, with advanced computer processing detector in the sphere of high machining accuracy. The pneumatic valve body material as pipe material, can appear uneven stress, not because of the earthquake and the vehicle through the ground deformation, occurs when pipe ageing resistance. Sealing ring ontology using content % C ( Carbon PTFE material, guarantee completely without leakage, %。
