Description
Technical field
The utility model belongs to combustible gas leakage detection alarm technical field, has more particularly to one kind detachable anti-
The gas power car and boat combustible gas probe of helmet shell.
Background technology
Gas detector is applied to flammable or toxic and harmful gas hazardous area be present, quilt in energy continuous monitoring air
The content or concentration surveyed within gas burst lower limit.It is widely used in combustion gas, petrochemical industry, steel, coking, electric power, household, car
The fields such as ship, it is to ensure property and the preferable detection device of personal safety.Combustible gas probe core component is gas sensing
Device, its operation principle are：When fuel gas reaches the reception window of gas sensor by diffusion, with the change of gas concentration
Produce corresponding resistance variations, detector will become corresponding voltage or current signal according to the change, at amplified and signal
Reason, when gas concentration exceedes alarm setting value, detector can produce leakage alarm signal., should if sensor window is intake
Sensor will fail.For waterproof, a waterproof ventilated membrane is pasted in the reception window of sensor, this is doing for the common detector
Method.Detector is applied in adverse circumstances, such as the enging cabin of automobile, often because in waterproof and breathable after the cooling such as greasy dirt steam
Schmutzband is formed on film or blocks air-vent above head protector, prevents detected gas from entering the reception window of gas sensor
Mouthful, probe functionality can be caused to fail.Automobile-used combustible gas probe is used for fuel gas power car (ship), detects fuel gas
Leakage.When detecting that target gas levels exceed alarm setting value, leakage alarm signal can be sent to controller, controller hair
Go out sound and light alarm signal, remind driver to confirm leakage, and adopt an effective measure, when preventing that gas leakage concentration from reaching explosion limit
Such as run into naked light to explode, avoid causing the heavy losses of personal safety and property.
The automobile-used combustible gas probe of prior art, head protector and probe body are integrated, when in greasy dirt steam ring
Border, the air admission hole of fixed protection cap or the waterproof ventilated membrane of sensor of detector are easily blocked, and make sensor and detector
Initial failure.Reduce the service life of detector.If changing the necessary integral replacing detector of detector, this, which is increased by user, makes
Use cost.
If waterproof ventilated membrane can at any time or periodic replacement, it is possible to extend detector working life, while reduce use
Family use cost, here it is the design aim of dismountable head protector.If head protector is non-exchange, overall detection can only be changed
Device, customer using cost increase.After using replaceable head protector, a part for the simply detector of replacing, it is easy to clean
Change waterproof ventilated membrane or change head protector it is cheap, customer using cost can be substantially reduced.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of head protector and its part can change, sealed reliable and
Automobile-used combustible gas probe simple in construction.
The technical solution adopted in the utility model is：A kind of automobile-used combustible gas probe, including head protector, with it is described anti-
The probe body of helmet connection, the pcb board in the probe body, be integrated on the pcb board with it is described anti-
The gas sensor that helmet is engaged, the head protector include protection cap main body, waterproof ventilated membrane, pressure ring, O-ring, the protection
Cap main body is threadedly coupled with the probe body.
Further, O-ring installation groove is set on the probe body, set on the probe body anti-
Helmet rotation starts and termination flag；The pressure ring periphery is provided with tip degree.
The beneficial effects of the utility model are：Head protector is detachable, can clean or change in time after dismounting, it is this can be with
Local replacing or the detector of maintenance can substantially reduce use cost, increase service life.There is protection on probe body
The rotation beginning of cap and termination flag, installing/dismounting is easy to operate, ensures that the combination of head protector and probe body is closed.Pressure ring
The tip degree of periphery can ensure the inner headed face tight connecting of pressure ring and head protector, can with sealed water-proof air permeable film edge,
Reach waterproof and effect is fully sealed.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings：
As shown in Figure 1 to 4, the detector that automobile-used combustible gas probe includes head protector, is connected with the head protector
Shell 1, the pcb board 2 in the probe body 1, it is integrated in what is be engaged on the pcb board 2 with the head protector 1
Gas sensor 11, the head protector 1 include protection cap main body 10, waterproof ventilated membrane 9, pressure ring 8, O-ring 7, the helmet main body
10 are threadedly coupled with the probe body 1.O-ring installation groove is set on the probe body 1, makes head protector with visiting
Surveying device shell 1 being capable of excellent sealing.Head protector is set to rotate beginning and termination flag 12 on the probe body 1, from mark
Will beginning rotates head protector and terminated to mark termination, and installing/dismounting is easy to operate.The periphery of pressure ring 8 is provided with tip degree,
Namely certain taper, it can reach waterproof with better seal waterproof ventilated membrane edge and effect be fully sealed.Detection
The front end of device shell 1 sets connector plug 13.
As shown in figure 5, detector parts are followed successively by since top, protection cap member includes protection cap main body 10, prevented
Water ventilated membrane 9, pressure ring 8, O-ring 7, the top surface and top for protecting cap main body 10 are provided with air-vent；Head protector and probe body 1
Combination, probe body 1 be provided with place O-ring groove, top has the rotation beginning of head protector and termination flag, front end to set
Put connector plug；Pcb board 2 is arranged within the probe body 1, and gas is integrated in the position corresponding with head protector of pcb board 2
