A kind of novel liquid level liquid temperature measurement sensor
Technical field
This utility model is related to a liquid level temperature measurement sensor device, is particularly suitable for nuclear power station and other irradiation rings
Liquid level temperature measurement sensor under border.
Background technology
At present, the high temperature in the pressure vessel of pressurized-water reactor nuclear power plant or thermal power plant, high-pressure boiler or liquid storage tank are this kind of
Temperature or liquid level sensor that the occasion of high reliability request is used, are that one-parameter is measured mostly, i.e., one sensor is individually surveyed
The reliability of amount temperature or liquid level, the occasion of these high reliability requests, its temperature and level gauging is directly connected to production and sets
Standby safety and personal safety, so in the urgent need to the temperature and liquid level in measurement pressure resistant vessel while a kind of high reliability
Integrated transducer.
But the sensor measurement assembly of existing electric contact liquid level emasuring device is mostly using the design of column type profile
Mode, by separately installed for the electric contact mounting flange in cylinder, this column type sensor measurement assembly, as liquid level is surveyed
The scope of amount is more and more wider, and the electric contact number that electric contact liquid level emasuring device is arranged is more, the length of sensor measurement assembly
To also become longer, when electric contact is installed in the cylindrical measurement assembly, also become further difficult;While the longer cylinder of length
Shape outer tube processing and transportation in be susceptible to deformation situations such as, also to can to later stage sensor measurement assembly function and
Service life causes the impact that can not be estimated.
Utility model content
The purpose of this utility model be in order to overcome the shortcomings of above-mentioned installation difficulty, be affected by human factors larger, there is provided
A kind of design is more reasonable, easy for installation and meets the liquid level temperature measurement sensor used under severe environmental conditions.This new
Type liquid level temperature measurement sensor, can reduce difficulty when electric contact is installed and keep in repair in the measurement assembly, while can also prevent
Only measurement assembly produces the adverse effects such as deformation in processing and transportation.
In order to solve above-mentioned technical problem, this utility model is accomplished by:
A kind of novel liquid level liquid temperature measurement sensor, including U-type groove steel, hollow type front panel, seal box, connector, armour
Loading electrode and proof armored platinum resistor, the hollow type front panel are mounted at the opening of U-type groove steel, and U-type groove steel and hollow out
Formula front panel is collectively forming a closing space, the bottom of U-type groove steel be provided with anti-fall be caught, treat for preventing measuring cell from falling into
In liquid, the seal box is located at the top of U-type groove steel, is provided with connector at the one side of seal box, the sheathed electrode and
The proof armored platinum resistor is separately mounted in U-type groove steel.
Further, this utility model also includes flange, and the flange is by the way of welding in U-type groove steel
Offer in portion, and flange for fixing the through hole of sheathed electrode and proof armored platinum resistor.
Preferably, the number of the sheathed electrode is for multiple, and sheathed electrode order arrangement is installed up and down.
The sheathed electrode and proof armored platinum resistor are respectively and fixedly installed to not by the way of weld bolt adds installation nut
On same flange.
Compared with prior art, this utility model has the advantage that:
(1), compared with column type measurement assembly, dismountable U-type groove steel construction is simpler for this utility model, install and
Convenient during maintenance, the intensity of whole measurement assembly can be strengthened, the deformation caused because of external force during transport and use is prevented;
(2) measurement assembly is needed to measure by connector installed in the side of seal box when sensor measurement assembly is arranged on
During the edge in pond, signal cable is in smooth-going state naturally, will not produce bending.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, each labelling is respectively:1st, U-type groove steel, 2, hollow type front panel, 3, anti-fall be caught, 4, seal box, 5, connect
Plug-in unit, 6, sheathed electrode, 7, proof armored platinum resistor, 8, flange.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of novel liquid level liquid temperature measurement sensor, including U-type groove steel 1, hollow type front panel 2, sealing
Box 4, connector 5, sheathed electrode 6 and proof armored platinum resistor 7, the hollow type front panel are mounted at the opening of U-type groove steel,
And U-type groove steel and hollow type front panel are collectively forming a closing space, the bottom of U-type groove steel be provided with anti-fall be caught 3, for preventing
Only measuring cell is fallen in testing liquid, and the seal box is located at the top of U-type groove steel, is provided with and patches at the one side of seal box
Part, when this measurement assembly is installed in the edge in pond to be measured, what signal cable can be smoothed out naturally is arranged in pond edge, will not
Bending is produced, affects the transmission of signal, the sheathed electrode and the proof armored platinum resistor to be separately mounted in U-type groove steel, described
The number of sheathed electrode for multiple, and sheathed electrode order arrangement is installed up and down.
Further, this utility model also includes flange 8, and the flange is discrete installed in U-shaped by the way of welding
Inside channel-section steel, and offer on flange for fixing the through hole of sheathed electrode and proof armored platinum resistor, the sheathed electrode and armouring
Platinum resistance is separately mounted on the mounting flange of diverse location, by being distributed in by the way of weld bolt and installation nut
The sheathed electrode of diverse location is making liquid level information discrete output.
The above is only embodiment of the present utility model, states again, for the ordinary skill people of the art
For member, on the premise of without departing from this utility model principle, some improvement can also be carried out to this utility model, these improvement
Also list in this utility model scope of the claims.
