Description

Special zirconia zirconium pond

Technical Field

The utility model relates to an analysis appearance zirconia field specifically is a special zirconia zirconium pond.

Background

The zirconia zirconium pool is the core sensor part of zirconia and is used for meeting the requirement of measuring the oxygen concentration of a sample. General zirconia zirconium pond adopts the ring flange fixed, leads to the outside lead wire can't be drawn forth, therefore the outside lead wire in zirconia zirconium pond can only be connected in the ring flange, and the external transmission signal of rethread ring flange, and the ring flange contact surface is great, and as the conduction face of signal, the error is great, and is great to measurement accuracy influence, and the ring flange fixed mode leads to zirconia to make up the head size great moreover, and the installation is maintained inconveniently.

Disclosure of Invention

An object of the utility model is to provide a special zirconia zirconium pond to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a special zirconia zirconium pond, includes the zirconium pond, the outer end in zirconium pond is provided with the threaded connection seat, be provided with outer lead wire and internal lead on the zirconium pond, outer lead wire and internal lead wire pass threaded connection seat and outside electric connection, and outer lead wire and internal lead wire all are fixed with the threaded connection seat is sealed.

As a further aspect of the present invention: and a metal O-shaped ring is arranged at the tail part of the threaded connecting seat.

As a further aspect of the present invention: and a wrench step is arranged at the outer end of the threaded connecting seat.

As a further aspect of the present invention: the thread of the threaded connecting seat adopts a large thread.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model adopts the external thread mode which is suitable for long-term use in high temperature state to connect with the equipment, which can make the equipment more stable in operation and more convenient in maintenance and replacement of the zirconium tank; the lead adopts a unique threaded inner penetrating structure, so that the problem that the lead on the outer side of the zirconium pool cannot be led out is solved skillfully, and the accuracy of instrument signal response can be improved.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Referring to fig. 1 and 2, in an embodiment of the present invention, a special zirconia zirconium pond includes a zirconium pond 1, an outer end of the zirconium pond 1 is provided with a threaded connection seat 4, an outer lead 3 and an inner lead 2 are provided on the zirconium pond 1, the outer lead 3 and the inner lead 2 pass through the threaded connection seat 4 to be electrically connected with the outside, and the outer lead 3 and the inner lead 2 are both fixed to the threaded connection seat 4 in a sealing manner.

The afterbody of threaded connection seat 4 is provided with metal O type circle 5, and metal O type circle 5 is used for solving the sealed problem when the high temperature operation, the outer end of threaded connection seat 4 is provided with spanner step 6, the screw thread of threaded connection seat 4 adopts big thread, and 1 high temperature operation back in zirconium pond can be solved to big thread, dismantles convenient problem.

The working principle is as follows: when the device is used, the zirconium oxide pool is installed and connected, then the lead is connected with a circuit, when the zirconium oxide starts to work, the zirconium oxide pool is heated to more than 600 ℃, the measured process gas passes through the outer side of the zirconium oxide pool, the process gas can be ensured not to leak to the inner side of the zirconium pool through the threads and the metal O-shaped ring, and the measurement accuracy is ensured; at the moment, charge movement can be generated on the inner side and the outer side of the zirconium oxide pool, an inner side signal is led out through an inner side lead, an outer side signal lead is led out through the bottom of the thread, and a mV voltage signal generated between the inner side and the outer side is subjected to signal processing through an electric part of the instrument, so that the measurement of the oxygen concentration of the process gas is realized.

The utility model adopts the external thread mode which is suitable for long-term use in high temperature state to connect with the equipment, which can make the equipment more stable in operation and more convenient in maintenance and replacement of the zirconium tank; the lead adopts a unique threaded inner penetrating structure, so that the problem that the lead on the outer side of the zirconium pool cannot be led out is solved skillfully, and the accuracy of instrument signal response can be improved.
