Description
Technical field
The utility model relates to a kind of thermometer, is specifically related to a kind of thermometer for petrochemical industry pump valve mechanical seal rinsing system.
Background technique
At present, be applied to the thermometer of petrochemical industry pump valve mechanical seal rinsing system, its structure generally includes dial plate, feeler and for the three-way interface of connected system pipeline, the upper end of feeler is fixedly connected with dial plate, the lower end of feeler penetrates in three-way interface, and described feeler penetrates on the lower end in three-way interface and is enclosed with protecting jacket, in the prior art, people normally directly weld described protecting jacket and three-way interface to realize the fixed installation of thermometer, so just cause forming between thermometer and system pipeline non-removable being fixedly connected with, thereby be unfavorable for maintenance or the replacing of thermometer.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of thermometer for petrochemical industry pump valve mechanical seal rinsing system of being convenient to maintenance and changing.
For achieving the above object, the utility model provides a kind of thermometer for petrochemical industry pump valve mechanical seal rinsing system, comprise dial plate, feeler and for the three-way interface of connected system pipeline, the upper end of feeler is fixedly connected with dial plate, the lower end of feeler penetrates in three-way interface, and described feeler penetrates on the lower end in three-way interface and is enclosed with protecting jacket, described protecting jacket is detachably mounted on system pipeline by detachable member, described detachable member includes socket welding flange and protecting jacket flange, socket welding flange is set on protecting jacket and with system pipeline and is welded and fixed, described protecting jacket flange is set on feeler, and be welded and fixed with the end, upper end of protecting jacket, described protecting jacket flange is positioned at socket welding flange top, detachably fixing by connecting bolt between protecting jacket flange and socket welding flange.
The beneficial effects of the utility model are: adopt said structure; owing to being to be detachably mounted on system pipeline by detachable member at the protecting jacket described in the utility model; described detachable member includes socket welding flange and protecting jacket flange; therefore turn on the connecting bolt between described socket welding flange and protecting jacket flange; just thermometer can be disassembled from system pipeline, thereby be convenient to maintenance and the replacing of thermometer.
The utility model can further be set to also be provided with welded pipe between described socket welding flange and three-way interface; described welded pipe coaxial package is on protecting jacket; insert in socket welding flange the upper end of welded pipe; and upper end outer surface and the socket welding flange of described welded pipe are welded and fixed; insert in three-way interface the lower end of welded pipe; and lower end outer surface and the three-way interface of described welded pipe are welded and fixed, between the inner ring surface of described welded pipe and protecting jacket outer surface, form the space that can flow into for system media.
Employing said structure arranges; in the time that system pipeline is normally worked; system media will fully fill up the space forming between described welded pipe inner ring surface and protecting jacket outer surface all the time, thus make feeler can be more truly induction system medium temperature directly, greatly improve the testing precision of thermometer.
The utility model also can further be set to also be provided with seal arrangement, the preferred graphite metal spirotallic gasket of described seal arrangement between described protecting jacket flange and socket welding flange.
Employing said structure arranges, and sets up seal arrangement and can effectively prevent that foreign matter from entering in system pipeline by the gap between protecting jacket flange and socket welding flange.
Brief description of the drawings
Fig. 1 is structural drawing of the present utility model.
