Brake pneumatic valve is analysed the characteristic and advantage?

in recent years, with the benign development of private economy in our country, the pneumatic double disc brake pneumatic valve is widely used, particularly in the field of industry, today, small make up take you to understand what are pneumatic double disc brake pneumatic valve characteristics and advantages.
pneumatic double disc brake characteristics of pneumatic valve:
and double block and emission features: pneumatic double disc brake pneumatic valve adopts floating pneumatic seat spring preload, regardless of the pneumatic valves are in a state of full open or close, upstream and downstream side of the pneumatic valve seat make fluid blocking, pneumatic double disc brake pneumatic valve pneumatic valve body lumen retentate emissions by pneumatic valve discharge.
function, automatic pressure release: pneumatic double disc brake pneumatic valve body cavity for medium temperature increase caused by the abnormal pressure, do not need through the security pneumatic valve, pneumatic seat function is only can automatic pressure release, the pneumatic double disc brake pneumatic valve to ensure safety is very important in conveying liquid medium.
, the structure of the fire safety: pneumatic double disc brake of pneumatic valve has function of fire safety, its design, manufacture all follow API and APIFA specification requirements.
pneumatic double disc brake of the pneumatic valve advantages:
and sealing emergency greasing rescue: caused by foreign bodies or fire in our medium pneumatic double disc brake pneumatic valve seat seal unexpected failure, on the pneumatic valve provides a connection to a quick note grease gun, convenient and quick to sealing grease injection to the pneumatic valve seat sealing parts, reduce leakage.
and reliable pneumatic double disc brake pneumatic valve stem seal and low operating torque: in addition to setting the standard of sealing ring, the packing gland is also equipped with the 'O' type sealing ring, double seal to ensure the reliability of the pneumatic valve stem seal; Adding graphite packing and sealing grease injection make fire after pneumatic double disc brake pneumatic valve pneumatic valve stem leakage to a minimum. Pneumatic valve rod sliding bearing and thrust bearing pneumatic valve operation.
and full size or reducing: can choose according to need full size or reducing structure. All sizes of pneumatic double ram pneumatic valve aperture is consistent with the pipe diameter, flow passing the gate to facilitate pipeline cleaning.
pneumatic valve pneumatic valves, pneumatic double disc brake lever can be lengthened: according to the need of installation or operation of pneumatic double disc brake pneumatic valve pneumatic valve stem for longer. Pneumatic double disc brake pneumatic valve is particularly suited to the occasion of city gas and so on need to be buried laying pipelines. Extended pneumatic valve stem size according to customers need to be addressed.
, flexible operation, pneumatic valve adopts pneumatic double disc brake has a small friction coefficient and good self-lubrication pneumatic seat and pneumatic valve rod bearing, greatly reduced the pneumatic valve operating torque. So even in the case of the provided no sealing grease, is also a long-term mobility of pneumatic double disc brake pneumatic valve operation.
