Abstract
The invention discloses a calibrating box of an exhausting device, and belongs to detecting devices of gas measuring equipment. The calibrating box of the exhausting device comprises a rectangular box body and a top cover, and is characterized in that a power wire hole and an air inlet and outlet hole are formed in the sidewall of the box body; and at least four probe inserting holes with rotatable sealing covers are formed in the top cover. The calibrating box has the advantages that the calibrating box is sealed by a plurality of times, and a probing device is convenient to pick without opening the cover of the calibrating box, therefore, the gas with rated concentration is kept in the box all the time. The calibrating box can prevent gas from spreading into the air, reduce the gas waste, and also can greatly reduce the usage of standard gas and pure gas, therefore, the efficiency can be improved, and the cost can be reduced; and furthermore, the requirements on occupational health and environmental protection are met.
Description
Technical field
The invention belongs to the pick-up unit of gas measuring apparatus.
Background technology
Combustible gas probe is the gas examination checkout equipment of using always, in the place widespread use of using inflammable gas.Combustible gas probe need be demarcated after debugging to guarantee to detect the accuracy of data.Existing scaling method is: method one; Use standard gas carries out calibration check one by one through the probe position of calibration mask alignment detector; The whole disperses of gas are in air like this, and promptly having wasted a large amount of standard gas, not meet worker's occupational health safety requirements and efficient again low.It is uneconomical also not environmental protection.Method two is to use the demarcation case to carry out calibration check.1. detector integral body is put into case during calibration check; 2. connect back energising preheating debugging detector with pick-up unit; 3. build case lid; 4. analyze through infrared spectrum analyser with pure gas and set concentration gases injection demarcation case, 5. transfer the potentiometer on the detector that detector is carried out proving operation with straight screwdriver; Shortcoming is to operate very inconvenience; And place detector seldom in one the case, efficient is extremely low, and demarcating finishes must take away case lid detector is taken out from demarcate case; The gas that FCL is set concentration all disperse still repeats above step when calibration check once more in air.Not only waste gas but also be unfavorable for that workers health safety and work efficiency are extremely low.
Summary of the invention
In order to overcome the deficiency that the FCL gas-dispersion when picking and placeing detecting device of existing demarcation case had not only been wasted gas but also had been unfavorable for workers health safety; The present invention provides a kind of exhaust apparatus to demarcate case, and this exhaust apparatus is demarcated case can reduce the outside disperse of gas of demarcating in the case.
The technical solution adopted for the present invention to solve the technical problems is: a kind of exhaust apparatus is demarcated case; Comprise rectangular parallelepiped casing, top cover; It is characterized in that: wall box is provided with power lead hole and air inlet/outlet, and top cover is provided with at least 4 probe inlets that have rotatable gland bonnet.
Between described casing top mouth and the top cover sealing gasket is housed, the fan Fixture that fan is housed is being fixed at two ends in the casing.
The described detector patchhole structure that has rotatable gland bonnet does; Have concentric circle holes on top cover bottom plate and the top cover top plate; Be inlaid with the plain cushion rubber seal identical in the circular hole of top plate with its thickness; Rubber gasket is being fixed in the gland bonnet bottom surface of cam-shaped, and gland bonnet is fixed on the top cover by fixed screw.
The method of using the present invention to demarcate detecting device is: 1. detector is placed in and connects back energising preheating with pick-up unit on the worktable and debug detector; 2. will demarcate gland bonnet on the case top cover is threaded to open state and inserts the detector probe position from probe inlet and demarcate the case; 3. analyze through infrared spectrum analyser with pure gas and set concentration gases injection exhaust apparatus demarcation case; 4. open and demarcate small fan in the case, the gas that gets in the case is fully mixed; 5. gas reaches when setting concentration in analyser shows the demarcation case, regulates the detector potentiometer with straight screwdriver detector is carried out proving operation; 6. demarcate the detector that finishes demarcating on the case and take off, gland bonnet is rotated to sealing state;
The invention has the beneficial effects as follows that and detector takes conveniently, need not open bid and decide case lid, remains the setting concentration gases in the case owing to demarcate case and adopt multiple-sealedly.Not only prevented that gas-dispersion from air but also reduce the gas waste, also having significantly reduced the use of standard gas and pure gas, and reduced cost thereby raise the efficiency, and then also meet occupational health and environmental requirement.

Embodiment
Embodiment of the present invention is, and is as shown in the figure:
Between described casing top mouth and the top cover sealing gasket 5 is housed, the fan Fixture 6 that is used to install fan 10 is being fixed at two ends in the casing.
The described detector patchhole structure that has rotatable gland bonnet does; Have concentric circle holes on top cover bottom plate 15 and the top cover top plate 4; Be inlaid with the plain cushion rubber seal 3 identical in the circular hole of top plate with its thickness; Rubber gasket 2 is being fixed in the gland bonnet bottom surface of cam-shaped, and gland bonnet is fixed on the top cover by fixed screw 9.
The method of using the present invention to demarcate detecting device is: 1. detector is placed in and connects back energising preheating with pick-up unit on the worktable and debug detector; 2. will demarcate gland bonnet on the case top cover is threaded to gland bonnet open state 14 and inserts the detector probe position from probe inlet and demarcate the case; 3. analyze through infrared spectrum analyser with pure gas and set concentration gases injection exhaust apparatus demarcation case; 4. open and demarcate small fan in the case, the gas that gets in the case is fully mixed; 5. gas reaches when setting concentration in analyser shows the demarcation case, regulates the detector potentiometer with straight screwdriver detector is carried out proving operation; 6. demarcate the detector that finishes demarcating on the case and take off, gland bonnet is rotated to sealing state.
