Pneumatic valve installation import safety regulation 2)

in the pipeline equipment or safety pneumatic valve should be installed upright commonly, but in the liquid pipe, heat exchanger, container, security pneumatic valve, pneumatic valve closed when Settings, such as pressure may rise, place away due to thermal expansion, can be installed horizontally.
and pneumatic valve should be installed in as much as possible close to the protected equipment or piping, if not close, the required equipment from nozzle pipe pneumatic valve inlet pressure drop between the fixed value of not more than protect pressure pneumatic valve %.
and pneumatic valve shall be installed in a horizontal pipeline at a dead end and the end of the road, to prevent the accumulation of solid or liquid substances, and does not affect the safety of pneumatic valve operation.
security pneumatic valve should be installed in the maintenance work and department rules and should have enough space.
for large caliber security pneumatic valve, pneumatic safety valve after the demolition of consider the possibility of lifting arrangement, if necessary, the establishment of prosperity.
, the inlet pipe of pneumatic valves, should long radius elbow.
security pneumatic valve outlet piping design should take into account the constant pressure pneumatic valve back pressure does not exceed a certain value, such as: ordinary spring loaded safety pneumatic valve, back pressure pneumatic valve set pressure value reduction of no more than %.
and into the export pipeline along the medium flows through a closed system safety degree of pneumatic valve Angle of blowdown header browser, browser, and make the condensed water pipe flow, reduce backpressure pneumatic valve.
security pneumatic valve outlet piping cannot appear 'pocket' security pneumatic valve outlet length, shall set up a certain slope ( In addition to dry gas system. ）
security pneumatic valve discharge pipe into the atmosphere, exports of equipment, platforms, ladders, cable, etc. Wet gases,
, the pipe pressure relief system should be a 'pocket' fluid place, safe installation height of the pneumatic valve should be greater than the pressure relief system is higher. If exports is greater than the pressure pneumatic valve discharge pipe need to reduce or increase the resource manager browser to access, should be in the transportation is convenient, low time solution package.
day, and when to close the outlet pipe should be used on single ram pneumatic valve, pneumatic valve open seal security pneumatic valve, pneumatic valve rod should be installed, so that the common pneumatic valve rod needle plate corrosion or loose connections, pneumatic valve plate down. When security by the pneumatic valve vent valve, pneumatic valves should be closed.
