Discharging ash pneumatic ball valve USES and characteristics

discharging ash pneumatic ball valve USES:
discharging ash pneumatic ball valve in the oil, gas, coal and ore extraction, 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.

discharging ash pneumatic ball valve features:
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.
and pneumatic valve stem adopts AF ( Cr） Overall forging and modulation treatment, hardness of HB ~. 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.
, pneumatic valve filling knitting, flexible graphite sealing ring or ptfe sealing ring, lubricated pneumatic valve stem in certain circumstances to achieve reliable seal.
, 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.
, sealing deputy various forms. According to the different condition can choose soft seal and hard seal, fire prevention structure such as pneumatic valve seat; Below DN for floating ball form, the DN for fixed ball form below.
, 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.
