SD341X Flanged Telescopic Butterfly Valve product introduction
SD341X Flanged Telescopic Butterfly Valve produced and sold by Baigang valve group with automatic compensation for thermal expansion and contraction of the convenience of loading and unloading functions, used at temperatures below 120 ℃, the nominal pressure of 1.6MPa below the oil, chemical, power, papermaking, water supply and municipal construction and other industrial pipelines The best device for regulating flow and breaking fluid.
SD341X Flanged Telescopic Butterfly Valve working principle
Flange retractable butterfly valve is divided into three types:
A,
ordinary type: When used according to the design specifications of
expansion joints design and installation, such as the need to add limit
bolts, please indicate when designing.
B, fixed limit type: it can
be retractable, but also limit, with the telescopic part of the fixed
function of not letting its expansion. Its features are
multi-functional, wider scope of application.
C, lengthened: it is
the ordinary expansion telescopic extension of the butterfly valve
lengthened to make it the length of the length required by the user (not
including the amount of expansion), which is characterized by the
transformation of the old pipe, the valve on the original pipeline needs
to be updated Replacement, without the original pipeline on the
connecting part of the pipeline cut off, you can replace it. Extended
type selection should also be considered plus limit measures, such as
the limit please specify when designing.
SD341X Flanged Telescopic Butterfly Valve features:
1, sealing parts can be adjusted replacement, reliable sealing performance.
2, unique structure, flexible design, light weight, labor-saving, quick opening and closing.
3, telescopic butterfly valve can not only compensate for the thermal expansion and contraction shrinkage caused by the pipe temperature difference, but also for the maintenance of valve installation and replacement to provide convenience.
SD341X Flanged Telescopic Butterfly Valve installation Precautions:
1, Flange retractable butterfly valve must be placed flat before installation, do not bump freely, the operation is prohibited to remove the bracket.
2, Flange retractable butterfly valve factory structure length of the minimum length, installation, pulled to the installation length (ie, design length).
3, when the pipe length exceeds the telescopic valve installation length, please adjust the pipe interval, do not forcibly stretch the butterfly valve, so as not to damage the butterfly valve.
4, Flange retractable butterfly valve can be installed in any, do temperature compensation with the installation of the pipeline is completed, the direction along the pipe axis to be added at both ends of the bracket to prevent telescopic tube telescopic tube pulled out.
