Abstract
The utility model discloses a stationary combustible gas detector. The detector comprises a sensor component, a circuit board, an upper cover, an O-shaped sealing ring, a circuit board protection cover, a bottom box, an explosion-proof gasket, a sealing gasket, a block, a mounting base plate and a dust cover. The stationary combustible gas detector disclosed by the utility model is simple in structure, reasonable in design and low in cost, and is waterproof by adopting the sealing ring to seal the box body simultaneously, so that the service life of the detector is effectively prolonged, and the detector can be widely applied to various environments and is beneficial to promotion.
Description
Technical field
The utility model relates to a kind of inductive probe spare, relates in particular to a kind of fixed combustible gas probe.
Background technology
On gas industry, the technology that infrared gas sensor replaces the catalytic combustion sensor is a kind of large trend.Although the catalytic combustion sensor is widely used and low price, easy contaminated poisoning lacks the fail safe self check, require periodic maintenance and demarcation and maintenance and demarcation cycle short, and serviceable life is short.And combustible gas probe of the prior art does not possess water-proof function, is installed on the open air and is easily damaged by rainwater or wet environment.
The utility model content
The purpose of this utility model provides a kind of fixed combustible gas probe with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises sensor module; circuit board; loam cake; the O RunddichtringO; the circuit board over cap; end box; explosion-proof packing ring; packing washer; stop up; mounting base and dust cover; described circuit board is installed on the bottom in the box of the described end; described circuit board over cap is installed in the box of the described end by screw and is positioned at the top of described circuit board; described O RunddichtringO places the position between box of the described end and described loam cake; described loam cake is connected by socket head cap screw with box of the described end; described mounting base is arranged at the outer lower end of box of the described end; the side of box, the described end is provided with siphunculus; described sensor module places in the described siphunculus; described dust cover is installed on outside the described siphunculus; the opposite side of box of the described end is provided with air hole; described dust cover places in the described air hole; described obstruction is installed on described breather port, between described dust cover and the described obstruction described packing washer is housed also.
The beneficial effects of the utility model are:
The utility model is simple in structure, and is reasonable in design, with low cost, and by adopting the O-ring seal sealing box body, thereby reaches waterproof action, Effective Raise product serviceable life, and can be widely used in various environment, be beneficial to popularization.
