Pneumatic Flanged Thermal Power Plant Dry Ash Inlet Valve (GJQ641FM)
Characteristics:
This valve is applicable as an on-off device for pipelines containing abrasive dry ash, water (such as cinder water ) and the like in mines, paper making, chemical engineering and so on, as an on-off for pipelines with both soft grains and corrosive media. Its working nominal pressure is 1.0MPa, applicable temperature is below 200 Deg C, and air supply pressure is 0.6-0.8MPa.
The inlet valve is integrated with the storehouse pump and cylinder drives the rocking arm to rotate by 90 Degree to achieve the valve's opening/closing function.
The inlet valve with such a structure can meet extremet conditions for pneumatic dry ash transportation in storehouse pumps. Its sealing surface with Fluorine rubber has a big containability for dry ash grains and is invulnerable to abrasion and resistant to a high temperature lower than 250 Deg C. The sealing element can be replaced directly. Its bell-shape chamber is invulnerable to ash accumulation, and the hand hole on its body makes it available to replace internal sealing parts online, easy for maintenance.
