Description
Technical field
The utility model relates to a kind of connection structures of enhanced Zirconium oxide oxygen sensor.
Background technique
Zirconia sensor is made of zirconium oxide (ZrO2) and metal fixed structure.Conventional oxidation zirconium oxygen on the market passes
Sensor, when the sensor of ceramic body is connect with metal structure, because of expansion coefficient difference and stress variation, in high temperature, high humidity and height
Under the site environment of pressure, there are easy gas leakage, the shortcomings that easy fracture, brought not to the oxygen content detection in industrial processes
Just, to be impacted to entire process flow.
Utility model content
The technical problem to be solved by the utility model is to provide one kind to be directed to harsh site environment, after improving
It is enhanced, have leakproofness good, thermal shock resistance is excellent and the enhanced Zirconium oxide oxygen sensor of simple installation advantage
Connection structure.
The utility model is achieved through the following technical solutions:
A kind of connection structure of enhanced Zirconium oxide oxygen sensor, including zirconia sensor, metal fixed flange,
Metal connects neck tube；The bottom of zirconia sensor be inserted in metal connection neck tube, zirconia sensor connect with metal neck tube it
Between by high-temperature seal adhesive or soldering be attached；The outer diameter that metal connects neck tube is less than the inner hole of metal fixed flange
Diameter is attached between metal connection neck tube and metal fixed flange by welding, and metal connects the one of the bottom of neck tube
Crouched in part in the inner hole of metal fixed flange, metal connect formed between neck tube and metal fixed flange one it is open
Cavity.
The surface of zirconia sensor is coated with protective coating as a preferred technical solution,.
Metal connection neck tube is thin wall typed structure as a preferred technical solution,.
Metal fixed flange is made of stainless steel or heat-resisting alloy as a preferred technical solution,.
The surface light of zirconia sensor, metal connection neck tube, metal fixed flange as a preferred technical solution,
It is sliding.
The beneficial effects of the utility model are: 1, effective solution is because of two kinds of materials (ceramics and metal), in industrial ring
Zirconia ceramics body caused by the difference of stress variation ruptures under border.2, complete with the internal structure of oxygen detecting probe general at present
Full matching.Being changed without the structure to oxygen detecting probe can be used.3, structure fabrication is easy, and working service is convenient.4,
Certain thickness metal fixed flange can reduce the rate that moisture enters zirconia ceramics body, avoid high humility gas
Damage to zirconia ceramics body.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural perspective of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
In the description of the present invention, it should be understood that term " one end ", " other end ", " outside ", "upper", " interior
The orientation or positional relationship of the instructions such as side ", "horizontal", " coaxial ", " center ", " end ", " length ", " outer end " is based on attached drawing
Shown in orientation or positional relationship, be merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion institute
The device or element of finger must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this reality
With novel limitation.
In addition, in the description of the present invention, the meaning of " plurality " is at least two, such as two, three etc., unless
Separately there is clearly specific restriction.
In the present invention unless specifically defined or limited otherwise, term " setting ", " connection ", " passes through at " socket "
Wear ", the terms such as " grafting " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integral；
It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, can also indirectly connected through an intermediary, it can be with
It is the interaction relationship of the connection or two elements inside two elements, unless otherwise restricted clearly.For this field
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.
The connection structure of the enhanced Zirconium oxide oxygen sensor of one kind as depicted in figs. 1 and 2, including zirconia sensor
1, metal fixed flange 2, metal connect neck tube 3；It is inserted in metal connection neck tube, zirconium oxide sensing in the bottom of zirconia sensor
It is attached between device and metal connection neck tube by high-temperature seal adhesive or soldering；The outer diameter that metal connects neck tube is less than metal
The diameter of the inner hole of fixed flange is attached between metal connection neck tube and metal fixed flange by welding, metal
It connects and is crouched in a part of the bottom of neck tube in the inner hole of metal fixed flange, metal connects neck tube and metal fixed flange
Between formed an open cavity.
Working principle: being metal neck tube with zirconia ceramics connecting portion, the reduction of metal volume greatly reduces gold
The temperature change stress of category.Metal fixed flange connect neck tube with metal and is welded by interior horizontal connection structure, is formed
