Bimetallic thermometer used on heat supply pipeline, all using bimetallic thermometer protection pipe, is directly immersed in measured medium
The method of middle measurement temperature.In the case where Heating Season thermal power plant unit is continuously run, if bimetallic thermometer breaks down, palpus
Whole thermal power plant unit is stopped transport, then by after system decompression, new thermometer can be just re-replaced, time-consuming, shadow is not only changed
Heat supply is rung, and is repaired extremely inconvenient.
The content of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and there is provided a kind of movable external screw thread bimetallic thermometer
Protection sleeve pipe device, when solving current bimetallic thermometer and breaking down, changes must the stop transport technology of thermal power plant unit of thermometer and asks
Topic.
The utility model is achieved through the following technical solutions：
A kind of movable external screw thread bimetallic thermometer protection sleeve pipe device, including：Stainless steel protection sleeve pipe, its feature exists
In：The small head end of the stainless steel protection sleeve upper end and stainless steel step joint is welded, and bottom uses stainless steel plate plug
Closure；The stainless steel step joint is machined with internal thread close to stub end centrally along being axially arranged with through hole, through hole, institute
The small head end for stating stainless steel step joint is machined with external screw thread, by the external screw thread with being welded on tested heat supply pipeline
The internal thread connection of stainless steel pipe hoop joint, passes through the internal thread and the movable external screw thread of movable external screw thread bimetallic thermometer
Connection；The stainless steel protection cannula cavity fills conduction oil.
Further, the profile of the stainless steel step joint stub end is hexaplanar.
The utility model compared with prior art, due to stainless steel protection sleeve pipe with provided with internal and external threads stainless steel step
Formula joint is connected, and is connected, passed through with the internal thread for the stainless steel pipe hoop joint being welded on tested heat supply pipeline by external screw thread
Internal thread is connected with the movable external screw thread of movable external screw thread bimetallic thermometer；So the utility model be installed on high temperature, high pressure,
High flow rate, with corrosivity pipeline, once bimetallic thermometer breaks down in thermal power plant unit is continuously run, it is possible to achieve
Do not stop transport in thermal power plant unit, under conditions of not pressure release, quick-replaceable bimetallic thermometer.

Embodiment
With reference to accompanying drawing, clear complete description will be carried out to the technical solution of the utility model below.
As shown in Figure 1, 2, 3, a kind of movable external screw thread bimetallic thermometer protection sleeve pipe device, including：Stainless steel protection
Sleeve pipe 1, the upper end of stainless steel protection sleeve pipe 1 and the small head end of stainless steel step joint 3 are welded, and bottom uses stainless steel plate
Plug 2 is blocked；The stainless steel step joint 3 centrally along in being axially arranged with through hole, through hole and being machined with close to stub end
Screw thread 3.2, the small head end of the stainless steel step joint 3 is machined with external screw thread 3.1, passes through the external screw thread 3.1 and welding
The internal thread connection of stainless steel pipe hoop joint 4 on tested heat supply pipeline 5, passes through the internal thread 3.2 and movable external screw thread
The movable external screw thread connection of bimetallic thermometer 7；The inner chamber of stainless steel protection sleeve pipe 1 fills conduction oil 6.
The profile of the stub end of stainless steel step joint 3 is hexaplanar 3.3.
In use, the local perforate for being easy to observe and overhauling in tested heat supply pipeline 5 first, by stainless steel pipe hoop joint 4
Welded in tapping with tested heat supply pipeline 5, while by the small of the upper end of stainless steel protection sleeve pipe 1 and stainless steel step joint 3
Head end is welded, and the bottom of stainless steel protection sleeve pipe 1 is blocked using stainless steel plate plug 2；Then stainless steel protection sleeve pipe 1 is inserted
Enter in tested heat supply pipeline 5, insertion depth must be over tested heat supply pipeline center, and can not contact tube wall, be pulled with spanner
Hexaplanar 3.3, the external screw thread 3.1 of stainless steel step joint 3 is connected with the internal thread of stainless steel pipe hoop joint 4, then will
The movable external screw thread of bimetallic thermometer is connected with the internal thread 3.2 of stainless steel step joint 3, finally in stainless steel protection sleeve pipe
Filling conduction oil 6 in 1, thus completes whole installations of bimetallic thermometer.Because protection sleeve pipe immersion media fraction is envelope
Close, so, the installation of bimetallic thermometer can be rapidly completed under thermal power plant unit normal operation.
The utility model uses all 304 stainless steels of material.Stainless steel protection sleeve pipe 1 will be carried out after machining
Bulge test, test pressure is necessary for 1.5 times of protection sleeve pipe operating pressure.
The essence that the utility model can be embodied without departing from utility model in a variety of forms, it should therefore be appreciated that
Above-described embodiment is not limited to foregoing details, and should widely be explained in claim limited range, therefore falls into power
Profit requirement or the change in its equivalent scope and remodeling all should be claim and covered.
