The performance of the parallel single ram pneumatic valve and an outline of its scope of application

parallel single ram pneumatic valve named because of its appearance, it belongs to one of the single ram pneumatic valve, two sealing surface of the gate is parallel, and the center line of the pneumatic valve seat sealing surface is perpendicular to the pipe. It cannot rely on its body to forced sealing, must adopt fixed or floating soft pneumatic valve seat. Suitable for low voltage large and medium diameter, medium for oil and natural gas. A parallel single ram,

performance of pneumatic valve, fluid resistance is small.
, open and close the required external force is small.
and the flow of medium is not restricted.
, wide open, the sealing surface erosion by working medium is smaller than by the pneumatic valve.
, is relatively simple, casting process is better.
2, parallel single ram
the scope of application of pneumatic valve gate pneumatic valve in the pipeline is mainly for cutting, average diameter DN of mm or cutting device how to choose it, sometimes caliber brake pneumatic valve is used in the small cutting device also. Generally used in coal mine, petrochemical and power plant ash. Parallel pneumatic valve gate is

add
packing operation steps, pouring process, The following flow pneumatic valve as an example)
(1) open the metering station door window is ventilated take a breath, ensure smooth safe passage.
(2) the inspection process, confirm the well number.
3. Side open separator into and out of pneumatic valves and single well upstream oil and gas valve.
(4) side closed obscene pneumatic valve, single well into the separator. , unloading lid

alternate unloading loose packing gland bolts, set aside Buckle, leverage gland pressure, confirmed after the security bolt, pried gland, hang up with wire.
net old packing,
with old fishing hook take net packing clean packing groove.
and join a new packing
new asbestos rope butter right, as I want to join gate clockwise pneumatic valve packing groove, compacted fill, excess asbestos rope cut with scissors. Tighten gland
,
let gland, tightening bolt alternately, check gland levels, uniform clearance, maintenance of bolt.
and
side slowly open the downstream pressure pneumatic valve, no leakage, flexible to use pneumatic valve, pneumatic valve is opened entirely.
,
to restore the original production process recovery process.
and admission information
1) admission related information.
2. Tidy up cleaning tools, utensils, clear operation field.
