Specific embodiment
The embodiment of the utility model is illustrated below in conjunction with the accompanying drawings, embodiment does not form the limit to the utility model
System：
A kind of Novel down-hole electromagnetic flowmeter, which is characterized in that electromagnetic flowmeter includes electrode section 2, the electrode portion
Exceptionally portion includes insulated part, and the insulated part includes insulation tapered sleeve 3, and the insulation tapered sleeve 3 is a part for insulation sleeve 5,
The insulation of electrode section and main body uses disposable engineering plastics injection molding；The insulated part is extruded in outside sensor pressure-bearing
Between shell A1 and sensor bearing shell B4.The substantive technique effect and its realize that process is that the technical solution at this place is played
It is as follows：This structure uses non-oil injection structure type Shooting Technique, and the insulation of electrode section and main body is noted using disposable engineering plastics
It is moulded into type sensor.Advantage：1. without using note silicone oil sealing；2. thoroughly solve the insulation problem of poor of electrode and main body；3.
Sensor portion partial pressure is solid structure without balance portion；4. easy cross line mating other instruments；5. sensor portion is divided into
Non-maintaining component, is now no longer repaired, and substantially increases production efficiency；6. Underwell electromagnetic flowmeter sensor is disposable injection
Molding, conformity of production is good, is universal product, available for a variety of different downhole instruments.Comparison diagram 5, the structure of this patent
Integrated degree is high, and manufacture is more convenient.
The magnetic sensor of centainly process and coiling coil is inserted into mechanism before injection, during in order to be molded
Facilitate installation, dismounting, demoulding, magnetic sensor lead-out wires of coil, electrode outlet line, instrument cross line etc. and draw simultaneously essence using copper post
Really it is fixed on mold；It is demoulded after the completion of injection, wiring copper post is exposed, checks insulation characterisitic, ensures per piece-root grafting line copper post over the ground
Insulation resistance is more than 500M i.e. between outer cover metal body, and sensor orientation is qualified.
The sensor bearing shell A1 and sensor bearing shell B4 respectively contains the protrusion of inner wall, the protrusion of inner wall
Insulation tapered sleeve is extruded in middle part.
In a creative way, each effect is individually present more than, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technique effect that more than structure is realized is realized, discounting for additional technical solution, this patent title is also
It can be a kind of novel sensor.It is not shown in figure part details.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen in claimed range.
