Abstract
The utility model relates to an oxygen-measuring sensor of zirconia, which can not only resist smash and collision but also be cut, processed and welded. The utility model comprises a filter, a zirconia tube, an armored thermocouple, a connected box, a shell and a gas labeled pipe, wherein, the metal filter is connected with the zirconia tube and an integrated constant temperature oven, and an electrode leader of the zirconia tube, a power leader of the integrated constant temperature oven and a temperature controlled couple are connected with the connected box and adopt armored structures; the shell is divided into two parts which are connected together by adopting a limited-rotation lock mechanism with openings oppositely assembled. The utility model is applicable for continuously monitoring oxygen content in various boilers, such as power, metallurgy, petrochemical industry, heating supply, etc.
Description
Technical field:
The utility model relates to sensor technical field, and exactly it is a kind of zircite oxygen transmitter.
Background technology:
Oxygen content is a very important techniques index in big-and-middle-sized Industrial Boiler, kiln, heating inner flue gas of the stove such as electric power, metallurgy, petrochemical complex, heat supply heating, it is for determining best combustion conditions and burning efficiency, an important parameters is provided, provides reliable assurance for burning to regulate automatically.Also have a kind of oxygen determination sensor to be applied on the car combustion engine, it is used for measuring, and oxygen concentration comes the oxygen determination sensor of controlling combustion engine burning in the combustion in IC engine tail gas, is that 00259974 disclosed patent documentation is exactly the oxygen determination sensor of such use as China Patent No.: CN1121177A, CN1217790A and application number.But existing oxygen determination sensor adopts porcelain filter mostly, is difficult to processing, and impact resistance is poor, fragile, what tubular zirconium-oxide electrode lead-in wire and constant temperature oven power supply lead-in wire and temperature control galvanic couple adopted is assembly structure, and reliability is not high, adopt flange arrangement during installation, it is convenient inadequately to connect.
Summary of the invention:
The purpose of this utility model provides a kind of zircite oxygen transmitter, and it is not only anti-pounds, also machinable and welding of impact resistance, has adopted sheathed structure, and the product reliability height, installs and fixes conveniently, solid and reliable.It comprises filtrator, tubular zirconium-oxide, armoured thermocouple, terminal box, shell, gas pipe, it is characterized in that: metallic filter (1) connects tubular zirconium-oxide (2) and integrated constant temperature oven (3), the contact conductor (4) of tubular zirconium-oxide (2) and the interior power supply lead wire of integrated constant temperature oven (3) (5) and temperature control galvanic couple (6) are connected in the terminal box (8) and all use sheathed structure, shell (7) is divided into two parts, adopts opening to link together to adorning spacing rotary locking mechanism between the two.
The utility model has the advantages that:
1, use metallic filter, good filtration effect has protective effect to tubular zirconium-oxide, anti-ly pound, impact resistance, and machinable and welding, easy to use, durable in use.
2, the tubular zirconium-oxide chemical analysis compatibility of can selecting the superior, moulding and electrode manufacturing process advanced person.The product quality excellence is measured accurately, stable performance, and the life-span is long.
3, zirconia contact conductor, constant temperature oven power supply lead-in wire and temperature control galvanic couple all adopt sheathed structure, guarantee this product reliability height, and be durable in use.
4, install and fix conveniently, solid and reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Structural representation when Fig. 2 installs for installing and fixing parts in the shell.
Embodiment:
In the utility model metallic filter 1 can make tested flue gas straightway enter in the tubular zirconium-oxide 2 detected, can filter again simultaneously and jeopardize the objectionable impurities of polluting tubular zirconium-oxide 2, and this metallic filter 1 can carry out machining and welding, especially anti-ly pound, impact resistance, have enough obdurabilities and plasticity, durable in use.These parts are installed in the head of measuring junction shell.Tubular zirconium-oxide 2 adopts sheathed electrode lead-in wire 4, thereby make the good quality of product, stable and reliable for performance, long service life, constant temperature oven 3 is designed to integral structure, adopts corundum tubulose body of heater, built-in spiral is swung to resistance wire and armouring power supply lead wire 5 and temperature control armouring galvanic couple 6, the constant temperature yard that can advantageously guarantee tubular zirconium-oxide 2 is evenly accurate, and any electromagnetic interference (EMI) of lining up, and reliability is high.These parts are installed in the shell 7, outside the tubular zirconium-oxide 2.On the integrated constant temperature oven 3 gas pipe 9 is housed also.Install and fix parts and adopt spacing rotary locking mechanism, these parts are two parts, a part is installed in the oxygen determination position of boiler, another part is installed on the shell of fixing this sensor, terminal box 8 is assemblied in the tail end of shell, be provided with the zirconia contact conductor in the box, constant temperature oven contact conductor, temperature control galvanic couple contact conductor.
