Ceramic feed pneumatic valve

feed pneumatic valve has been widely used in power plant ash system, but its wear resistance is an urgent need to solve the problem. Now with the widely application of the ceramic, ceramic discharge the emergence of the pneumatic valve solved the problem of the pneumatic valve wear resistance. Ceramic feed pneumatic valve is suitable for power plant dry ash pump feed conveyor system, storehouse, and also can be used in mining, paper making, chemical and other kinds of dry dust, water, etc have wear medium in the pipeline for opening and closing. Ceramic feed pneumatic valve technology reference to Armstrong pneumatic valve, shut down any direction all sealed, pneumatic valve pneumatic valve cover using WCB steel castings and seamless steel pipe, welding filler used, hard seal. Good sealing performance, high resistance to wear, small startup load, ash and knot less ash phenomenon, long service life.

ceramic feed pneumatic valve structure
disc and the brake lever unique structure design makes the process of pneumatic valve closed, pneumatic valve board spin. Thus realize the pneumatic valve plate coincided with pneumatic seat from sealing and pneumatic valve plate uniform wear, in the medium with abrasive materials can achieve lasting sealing performance. Opening and closing flexible, reliable sealing
the design of the cavity thoroughly avoids the problem of card plug, suitable for warehouse pump or economizer feed pneumatic valve switch, libraries, top pneumatic valve pneumatic actuators are nominal pressure for
. - 。 Mpa, pneumatic valve nominal pressure for Mpa
can meet a variety of installation and transmission device, manual, pneumatic, electric. Adopts pneumatic drive method, non-standard can customize

. More than ten thousand times the static test of fly ash, reliable sealing. Flow, gate, brake block, and use the structure of high performance ceramics manufacturing, wear resistance, long service life.

ceramic feed pneumatic valve performance advantage
ceramic feed pneumatic valve using structural ceramics as seal, scouring resistance, abrasion resistance is good!
ceramic material in the process of the pneumatic valve in the opening and closing a self-cleaning polishing function, pneumatic valve closing two-way sealing, flexible opening and closing.
non-standard, can be set up according to different working condition of purging mouth, automatic purging system, suitable for dry ash, slag slurry, material conveying medium, small startup load, less dust, no jamming and simple maintenance, long service life. Ceramic feed


pneumatic valve working principle of pneumatic principle for ceramic feed pneumatic valve: when the air supply from the aspirant port trendy, pneumatic valve rod drives the pneumatic valve plate movement down, pneumatic valve shut off. When the air supply from the air inlet fashionable words, pneumatic valve rod drives the pneumatic valve plate upward movement, pneumatic valve opens. Pneumatic valve plate and seat load between spring, spring force keeps the air valve plate pressure to the pneumatic seat guarantee the sealing of the pneumatic valve and allow the pneumatic valve plate in the vertical direction, which helps to compensate the heat bilges cold shrink of pneumatic valve parts, and can overcome any back pressure changes on the seal and prevent the influence of the particle medium enter between the sealing surface. In the process of opening and closing, pneumatic valve plate can produce rotation, caused the surface grinding, polishing, and because the aerodynamic body of channel eccentric, in open drainage discharge materials, can produce eddy current, materials forming spiral cleaning themselves pneumatic valve lumen. This pneumatic valve for double ram single seal, unique design of the pneumatic valve body cant guarantee the pneumatic valve lumen is not heavy. All of these features, making this kind of pneumatic valve has long service life and safe operation for your system provides a reliable guarantee.

ceramic feed pneumatic valve installation use points
, should read the instructions carefully before installation, and check the pneumatic valve type, size and technical parameters.
strictly prohibit the welds with the pneumatic valve flange, so as not to damage the pneumatic valve seal. Since the first reserved pneumatic valve installation distance should be appropriate, on both sides of the flange gasket.
, two pipe center center should maintain coaxial with the pneumatic valve size and flange face should level off, do not allow the large deflection of the flange surface, to guarantee the normal work of the pneumatic clamping and valve. Tighten bolts should be uniform.
