Abstract
The invention discloses an explosion-proof gas circuit detecting device with double-row gas holes. The explosion-proof gas circuit detecting device comprises a lampshade, an upper shell, a lower cavity, a main control board and a lining board, and is characterized in that the upper shell is connected to the bottom of the lampshade, and the lower cavity is connected to the bottom of the upper shell; the main control board is arranged inside the upper shell, and the lining board is arranged inside the lower cavity; the main control board is connected with the lining board by a hexagon stud combination. The explosion-proof gas circuit detecting device has the advantages that detection gas can flow into a detection cavity from the bottom of the explosion-proof gas circuit detecting device and can be directly guided to the front end of a sensor by the gas flow direction, so that the sensor can react quickly, and the response time of the explosion-proof gas circuit detecting device can be shortened.
Description
Technical field
the present invention relates to a kind of gas circuit detection architecture, particularly relate to a kind of gas circuit pick-up unit of explosion-proof double pore.
Background technology
at present in damp detection field, when the kind of object gas is more, and check point position not easily sample in pipeline or in deep-well environment time, need to connect movable type detector of bleeding and carry out gas detect.Detect gas in sampling process and be delivered to sensor air inlet pipeline by aspiration pump, then arrive sensor sample end through the gas circuit air intake structure of sensor front end.The air intake structure of tradition explosion-proof type sensor front end, because the test chamber space in the middle of cavity is comparatively large, air admission hole and vent port form convective structure, make detection gas can not enter sensor in time with fully, cause sensor response slow, affect the response time of checkout equipment.
Summary of the invention
for the problems referred to above, the object of the invention is one and make sensor response rapid, promote the gas circuit pick-up unit of a kind of explosion-proof double pore of its response time.
in order to realize object of the present invention, the technical solution adopted in the present invention is: a kind of gas circuit pick-up unit of explosion-proof double pore, comprises lampshade, upper shell, lower chamber, master control borad, liner plate; It is characterized in that: described lampshade bottom connects upper shell, connects lower chamber bottom upper shell; Described upper shell inside is provided with master control borad, and lower chamber inside is provided with liner plate; Be connected with hexagonal double-ended bolt between master control borad and liner plate.
pilot lamp is provided with in described lampshade.
described master control borad is provided with change-over panel, and change-over panel connects pilot lamp.
be provided with air admission hole bottom described lower chamber, both sides, lower chamber bottom are respectively equipped with left bank pore and right vent port.
described liner plate is provided with sealing gasket.
o-ring seal and set collar is provided with between described upper shell and lower chamber.
introducing device is provided with outside described upper shell.
beneficial effect of the present invention: detect gas and enter test chamber from bottom, airflow direction directly can draw detection gas to sensor front end, makes sensor response rapid, promotes its response time.
