Specific embodiment
The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model
Among the embodiment described range.
By in the space filling gas in electrode stem between sealing-plug in the utility model, to form similar air bag
Structure, thus to absorb the increased pressure of liquid expansion or solidification institute in electrode stem, even if still being protected under extreme temperature environment
The integrality of product is held, rupture or leakage will not be generated.And in temperature use temperature back to normal, electrode can still be protected
Hold normal performance.
Below by embodiment as described below, the implementation of the utility model is illustrated.
Embodiment 1
As shown in Fig. 2, one end of the electrode stem 1 of electrode is provided with end face seal plug 21 in the present embodiment, the other end is same
It is also equipped with end face seal plug 22.The sealing in space in electrode stem 1 is realized in the present embodiment using end face seal plug 21,22.Cause
This present embodiment can fill in the space of electrode stem 1 and store test solution.
Solidification glue 3 also is filled in the one end for being provided with end face seal plug 22 in the present embodiment, thus by end face seal plug 22
Thoroughly it is fixed on the end of electrode stem 1.And electrode cap 7 is also set up in one end that end face seal plug 22 is arranged in electrode stem 1 to wrap
Cover the end of electrode stem 1.Furthermore as shown in Fig. 2, the glass tube 5 being arranged in electrode stem 1 in the present embodiment is arranged in end face seal
Plug 21,22 and buffering sealing-plug 41.
The inner space of electrode stem 1 is divided into space A by the cushion seal plug 41 being arranged in electrode stem 1 in the present embodiment
And space B, and the stream of liquid or gas between space A and space B is completely cut off by the sealing structure of the composition of electrode stem 1
It is logical.
Test solution 6 needed for wherein filling electrode in space B fills air in the A of space, empty in another embodiment
Between can also fill the gases such as nitrogen.Space A constitutes airbag structure at this time, the generated pressure when liquid volume expands and increases
Power will push cushion seal plug 41 to slide in electrode stem 1 to end face sealing-plug 22, increase to alleviate test liquid volume
The pressure applied on electrode stem 1 and end face seal plug 21, ensure that the reliability of electrode.
