Technical field
The utility model relates to gas detecting instrument accessory technical field, especially relates to a kind of stationary gas detector with the probe protective cover.
Background technology
The stationary gas detection instrument generally is installed in the open-air open-air atmosphere.The breathing element of its probe itself can't be accomplished permeable watertight, that is to say that probe itself does not possess water-proof function, need add a protective cover and be used for waterproof.Want the concentration of combustible gas in the testing environment gas or poison gas, probe just need suck gas from environment and do analyzing and processing, is called sampling in the industry, so water-proof protection cover needs not only to breathe freely but also waterproof.Because detection instrument use meeting produces some drifts; These long time integrations that drift about; Can make the detection instrument reading inaccurate, and then possibly produce false alarm and maybe should report to the police and not report to the police, so detection instrument need regularly be demarcated in using; Promptly feed the gas of normal concentration and detection instrument reading adjustment is shown by standard value, with the drift of excision accumulation.Timing signal generally need use special-purpose demarcation fitting sleeve on probe, and one feeds standard gas with flexible pipe, and an outside exhaust is called the demarcation cap in the industry.At present traditional probe protective cover adopts inside and outside layering dislocation perforate method to realize the air permeable waterproof function, can prevent the probe water inlet, can guarantee the contact environment gas of popping one's head in again.But present probe protective cover major part is the bandgap calibration joint not, and each demarcation needs to go to the scene, and needs the well special-purpose demarcation cap of band, removes rainproof protective cover earlier, changes special-purpose demarcation cap, can demarcate, and demarcation also will be changed protective cover after finishing.Because a lot of on-the-spot probes are contained in very high place, and have combustible gas or poison gas, belong to the hazardous area, institute is so that proving operation is comparatively dangerous.Minority has the demarcation joint, and also because adopt layering dislocation open-celled structure, it is very big to make demarcation influenced by wind speed.Therefore be necessary to improve.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of stationary gas detector with the probe protective cover, when it has water-proof function; Good air permeability; Simultaneously, this probe protective cover has calibrating function, can directly be used for demarcating; Timing signal need not to change its special calibrating joint, and has the features of smaller that influences of demarcating wind-engaging.
To achieve these goals; The technical scheme that the utility model adopted is: the stationary gas detector is with the probe protective cover; Be installed on the front end of probe; Said stationary gas detector comprises outer cover with the probe protective cover, and the upper end and the probe of this outer cover is tightly connected, the lower end is sealedly connected with the demarcation joint, and the inner chamber of outer cover middle part is provided with the air permeable waterproof diaphragm.
Be provided with the inner cover of cup-shaped in the inner chamber of said outer cover, this inner cover is enclosed within on the air permeable waterproof diaphragm, and simultaneously, the bottom surface of inner cover is penetrating, and the bottom surface is provided with the bottom surface stainless steel cloth.
The side of said inner cover is penetrating, and the side is provided with the side stainless steel cloth.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: when 1, having water-proof function, and good air permeability.The stationary gas detector of the utility model forms enclosure space with the inner chamber and the air permeable waterproof diaphragm of the outer cover of probe protective cover, and probe is positioned at this enclosure space.Like this, when accomplishing to pop one's head in waterproof, probe can touch environmental gas.2, have calibrating function simultaneously, can directly be used for demarcating, timing signal need not to change its special calibrating joint.The other end of outer cover promptly is connected with the demarcation joint, and the gas outlet of demarcating joint is positioned at the formed space of outer cover equally.Timing signal need not into probe the demarcation joint to be installed separately, promptly can be probe feeding marked gas and demarcating.3, the influence of demarcation wind-engaging is less.Compare with the inside and outside layering dislocation open-celled structure of tradition probe protective cover, the utility model has used the air permeable waterproof diaphragm, can effectively isolate the influence of wind behind this tunic, thereby the influence of demarcating wind-engaging is less.4, extendability is good.The utility model makes the stationary gas detection instrument at timing signal, can remove the process that changes its special calibrating joint from, and is more convenient to operate.The more important thing is: the utility model makes long-range demarcation become possibility, as long as will demarcate in advance on the intake interface of the demarcation joint that gas circuit is connected to this protective cover, just can in the pulpit, realize long-range demarcation, and proving operation is made things convenient for a lot.
