Abstract

The utility model relates to an environmental gas analysis instrument in the petrochemical industry, in particular to an anti-oxidation protection case for an electrode of a gas analysis instrument. The anti-oxidation protection case comprises a case body and a case cover. The case cover is movably hinged with a rear side wall of the case body, a locking mechanism is arranged on the front side wall of the case body, an elastic sealing ring is arranged between the case body and the case cover, the shape of the elastic sealing ring is matched with the shape of the case cover and the shape of the case body, a protective gas inlet and an air outlet which are communicated with an inner cavity of the case body are arranged on a side wall of the case body, and a protective gas concentration indicator gauge is arranged on the case cover and is communicated with the inner cavity of the case body. Protective gas is filled into the relatively closed protection case, so that the content of oxygen in the protection case is about 2-3%, the electrode of the instrument can be protected when the environment analysis instrument is placed in the anti-oxidation protection case, the service life of the electrode is prolonged, and the anti-oxidation protection case is simple in structure, convenient to use and low in maintenance cost.

Description

Gas analysis instrument electrode anti-oxidation protection box
Technical field:
The utility model relates to a kind of petrochemical industry environmental gas analyzer device, particularly relates to a kind of gas analysis instrument electrode anti-oxidation protection box.
Background technology
Need in the petrochemical industry to use all kinds of environmental gas analyzer devices, such as explosimeter, oxygen analyser etc., this quasi-instrument is most of by built-in electrochemical gas sensor testing environment gas concentration.Adopting platinum such as oxygen electrode is negative electrode, and silver-colored silver chloride is anode, and oxygen can see through film and arrive negative electrode in the gas sample, under certain polarizing voltage, react, and the electric current that is directly proportional with ambient oxygen partial pressure of output.The use even if this quasi-instrument is not started shooting also can react with airborne oxygen and naturally consumption, and affect electrode life.
The utility model content
Goal of the invention of the present utility model is to overcome the defective that prior art exists, and realizes gas analysis instrument electrode anti-oxidation protection box.
For achieving the above object; the technical solution of the utility model: a kind of gas analysis instrument anti-oxidation protection box; comprise casing and case lid; described case lid and casing rear wall are movably hinged; be provided with latch mechanism with the casing front side wall; be provided with elastic seal ring between casing and the case lid; described elastic seal ring and case lid and box shape are complementary; wall box is provided with gas atmosphere inlet and the air out that is communicated with cabinets cavity, and case lid is provided with blanket gas concentration indicator gauge and is communicated with cabinets cavity.
Described air out level height is higher than the gas atmosphere inlet.
Described gas atmosphere inlet is nitrogen or inert gas entrance.
Described box house is provided with vertical netted dividing plate, or the bottom has the vertical clapboard of intercommunicating pore or connectivity slot.
Described latch mechanism comprise the tight locking button that is arranged on the case lid, be arranged on the lock sleeve on the casing and be installed in tight locking button and the locking trepanning in locking pin.
The beneficial effects of the utility model are:
1. this is practical by pass into nitrogen or inert gas in relatively airtight guard box, and the interior oxygen content of guard box is low to moderate about 2-3%, and environmental analysis is placed therein with instrument, and lowering apparatus anodizing speed increases the service life greatly.
2. the utility model case lid is provided with blanket gas concentration indicator gauge, can ensure better that institute's inflated with nitrogen or inert gas concentration reach request for utilization.
3. the utility model is simple in structure, make easily, and use, maintenance cost is low, easily promotion and implementation.
Description of drawings
Fig. 1 is the perspective view of this gas analysis instrument electrode anti-oxidation protection box;
