Q341W characteristics of turbine pneumatic ball valve and overview < / div >

pneumatic ball valve opening and closing is a piece of board, internal is a ball, it has the same revolving 90 degrees movements, only need to rotate 90 degrees of operating and small rotational torque can be closed tightly, completely parallel pneumatic valve body cavity for medium resistance is very small, straight flow channel, is generally thought that pneumatic ball valve switch is used, the most suitable for direct do alias also called switch pneumatic valve, with the development of the enterprise development, is now the pneumatic ball valve has been designed very precise, it not only has the switch function, and the throttling and control flow. In the oil, natural gas, coal and ore mining, refining processing and pipeline system; In chemical products, medicine and food production; In hydropower, thermal power and nuclear power production system; In urban and industrial water supply and drainage, heating and gas supply system; In the farmland irrigation and drainage systems; Widely used in metallurgical production system, is a kind of related to production and construction, national defense construction and people's life important mechanical products. Pneumatic ball valve closed in all kinds of pipeline system used to truncate or flow through media, the media in accordance with the procedures scheduled delivery to the specified point.
Q341W - 16 p stainless steel turbine pneumatic ball valve product features
1 and manual part of the steel plate can be used to neutralize the grip or the handle of the stainless steel casting. Handle sets limit structure, set in the position of the pneumatic valves open and close limit, when the pneumatic valve used in the key device, limit block has a lock can lock switch position to avoid wrong operation. Handle has obviously and off.
2, pneumatic valve stem adopts A182F ( 1Cr13） Overall forging and modulation treatment, hardness of HB220 ~ 250. Pneumatic valve rod through key spline or the parties connected to the handle, strong commonality, easy tear open outfit. Pneumatic stem with blow-out proof design.
3, pneumatic valve filling knitting, flexible graphite sealing ring or ptfe sealing ring, lubricated pneumatic valve stem in certain circumstances to achieve reliable seal.
4, according to the need, pneumatic ball valve can be designed as antistatic structure, the spheroid and pneumatic valve stem, pneumatic valve stem and valve body between the conductive spring, avoid electrostatic spark to ignite flammable material, ensure the security of the system.
5, sealing deputy various forms. According to the different condition can choose soft seal and hard seal, fire prevention structure such as pneumatic valve seat; 6 the following for floating ball form, DN200 for fixed ball form below.
6, pneumatic ball valve pneumatic seat in auxiliary seal structure can be set up, in the pneumatic seat and pneumatic valve stem parts adding greasing pneumatic valve, an emergency can be temporarily seal, and can according to need to lengthen the pneumatic valve stem with suitable buried laying venues
