Tianjin butterfly pneumatic butterfly valve production home to clip pneumatic valve to the installation steps

wafer butterfly valve pneumatic valve is one of the most common types of pneumatic valves in industrial piping, wafer butterfly valve pneumatic valve itself structure is small, only need to put the butterfly pneumatic valve in the pipeline both ends flanges, with stud through pipe flange and wafer butterfly valve pneumatic valve lock, can control the fluid of pipeline. Wafer butterfly valve pneumatic valve is especially suitable for narrow space or a shorter distance between the pipe, control pneumatic valve in the fully open position, the butterfly plate thickness is medium flows through the pneumatic valve when the only resistance, so by the pneumatic valve pressure drop is small, it has good flow control characteristics.
a, wafer butterfly valve, pneumatic valve before installation instructions:
and installation before operation, with spray washing to remove air piping on the external things, to match the tube surface, clean with water.
, carefully check whether use pneumatic valve is consistent with its performance specification; （ Temperature and pressure)
, to check whether there is sundry, pneumatic valve channel and sealing surface and keep clear of in time;
, when unpacking the case pneumatic valve to install in time, please do not arbitrarily loose any fastening screw or nut on pneumatic valves;
, wafer butterfly valve, pneumatic valve must use special butterfly pneumatic valve flange.
pneumatic valves, electric butterfly can be installed at any Angle of the line, in order to maintain convenient is not recommended to mount a horse.
, pneumatic butterfly valve flange during installation must ensure that the flange face and sealing rubber, screws evenly tighten, sealing face must be nicely complete; If there is a screw strength can appear uneven rubber bump stuck butterfly plate, or to resist butterfly plate in the pneumatic valve stem leakage.
2, wafer butterfly valve, pneumatic valve installation steps:
the wafer butterfly correct installation of pneumatic valve is related to the control of the pneumatic valve seal degree, and will not leak, including working in security, users should be understand installation process.
and placed pneumatic valve in pre installed between two pieces of the flange, pay attention to the bolt hole to neatly aligned.
, will be four pairs of bolt and nut gently insert flange hole, tighten nut slightly to correct the flatness of flange face;
, will be fixed on the pipeline flange using spot welding;
and remove the pneumatic valves;
, the flange welding completely fixed on the pipeline;
, stay cool joint before installation of pneumatic valve. Ensure pneumatic valves in the flange have enough space to prevent the pneumatic valve was damaged, and guarantee of the opening of the pneumatic valve plate has certain;
and correction of pneumatic valve position and tighten with four bolts, ( Be careful not to twist too tight)
and open the pneumatic valve, pneumatic valve plate to ensure free to open and close, and then make the pneumatic valve plate slightly open.
, cross balance. Tighten all nuts;
free to open and close, again confirmed pneumatic valve, note: make sure there's no touching the pipe pneumatic valve plate.
wafer butterfly valve pneumatic valve installed first before installation to must be flat, in casual knock against, when installation will be made after the length of the installation, it pulls in the design of piping, without special permission is not free to remove the wafer butterfly valve pneumatic valve, this is what we want to know before installation. At the same time you also know, wafer butterfly valve pneumatic valve can be installed in any position, but after the wafer butterfly valve pneumatic valve installation is complete you need butterfly laid along the pneumatic valve, a bracket for wafer butterfly valve pneumatic valve, and after stents once made, at the time of use is strictly prohibited to stand off.
