Pneumatic valve installation requirements and pipeline installation height level

the general requirements of pneumatic valve installation:
( ） Pneumatic valve should be located in easily accessible, easy to operate, repair. Rows pipe ( Such as pipeline in and out of the device) Pneumatic valve should focus on the layout, and consider setting operation platform and ladders. Parallel arrangement of the pneumatic valve in the pipeline, the center line should make even as far as possible. Clear distance between the wheel should not be less than mm, in order to reduce the pipe spacing, can decorate the pneumatic valve stagger.
( ） Partition equipment using pneumatic valves, in conditions allow time into the equipment nozzle directly, or close to the equipment. In the system can test more pipe when water pressure test, also can remove the maintenance, Or separated) Equipment without affecting the system.
( ） Accident treatment pneumatic valve, such as fire water use pneumatic valve, fire fighting steam use pneumatic valve and so on should be scattered layout, and take into account when the accident of safety operation. To decorate this kind of pneumatic valve after the control room, security wall, with factories outside, or a accident happened in a safe distance from the ground, to make the fire accident occurs, the operator can safe operation.
( ) Tower, at the bottom of the reactor, vertical container equipment of the pneumatic valve in the pipeline, not decorate in the skirt.
( ) Leads from the main branch, generally close to the roots and cut off the pneumatic valve is set on horizontal section.
( ) Aerodynamic lift check valve should be installed in horizontal pipe runs with the vertical lift check pneumatic valve can be installed in the tube medium flow in vertical pipe runs from bottom to top. Swing check pneumatic valve should be installed in horizontal pipe runs priority, also can be packed in tube medium flow in vertical pipe runs from bottom to top. Hand moving valve should be installed in the centrifugal pump suction pipe.
( ) Arrangement around the operation platform, operation platform, the pneumatic valve hand wheel center distance of edge should not be greater than mm, when the pneumatic valve rod and hand wheel and height is less than m above into platform, should make it not affect the operation of the operator and prevailing.
( ) Underground pipeline pneumatic valves should be located within a trench or pneumatic valve hole, when necessary, should be a pneumatic valve rod. Fire water pneumatic valve shaft shall be clearly marked.
the pneumatic valve is the most appropriate installation height distance operation. Meters.
horizontal line on the pneumatic valve, pneumatic valve stem direction can be determined in the following order: vertical upward. Level. The upward sloping °. Downward sloping °. Avoid straight down.
horizontal stem type pneumatic valve, when the pneumatic valve opens, pneumatic valve stem shall not affect traffic
