The utility model discloses an explosion -proof equipment can introduce the automobile exhaust that the oxygen content is extremely low airtight intracavity, through the oxygen concentration of oxygen test probe monitoring oil tank and airtight intracavity to feed back to the controller, controller control solenoid opening and closing, realizes reducing the oxygen content in the oil tank, thereby realizes the explosion -proof function of motor vehicle oil tank. The utility model discloses an explosion -proof equipment simple structure, convenient to use, safe and reliable.
Description
Technical field
The utility model relates to a kind of explosion protection, particularly relates to a kind of explosion protection for motor vehicle oil tank.
Background technology
Along with expanding economy, self-propelled vehicle becomes people's daily trip of conventional modern times instrument.Fuel tank is the critical component of self-propelled vehicle, and a large amount of inflammable substance is housed usually, and therefore, the safety problem of fuel tank, particularly Explosion-Proof become a very important problem.
For realizing oil tank anti-explosion function, German product ECN(ExploControl) automotive oil tank explosion-proof net adopt mode be: the explosion-proof oil-economization net placing a kind of aerated materials in fuel tank, this material is when contacting high temperature spark, can within the time of one of 20,000,000 points seconds, rapidly by heat absorption, keep temperature in fuel tank below detonation point, guarantee fuel tank can not Yin Gaowen explosion caused.But in use, because having installed the problems such as this net often causes oiling slow.
Utility model content
The purpose of this utility model is the explosion protection for motor vehicle oil tank providing a kind of structure simple, easy to use for the deficiencies in the prior art.
The utility model solves the technical scheme that its technical matters adopts:
A kind of explosion protection for motor vehicle oil tank, comprise fuel tank and be located at choker relief valve and the steam cock of tank surface, casing is covered with at tank surface, closed chamber is formed between casing and fuel tank, choker relief valve and steam cock are all positioned at closed chamber, controller and the first oxygen measurement probe is provided with in closed chamber, in closed chamber fuel tank surface on have some pores, each pore is sealed and installed with an electromagnetic valve, fuel tank internal is equipped with the second oxygen measurement probe, controller respectively with the first oxygen measurement probe, second oxygen measurement probe and each electromagnetic valve connect, casing is communicated with automobile tail pipe by pipeline.
Explosion protection of the present utility model, can vehicle exhaust extremely low for level of oxygen be introduced in closed chamber, two oxygen measurement probes real-time oxygen concentration detected in fuel tank and in closed chamber respectively, and by the information feed back of detection to controller, when detecting that the oxygen concentration in fuel tank is higher than the higher limit preset and higher than in closed chamber during oxygen concentration, Controlling solenoid valve is opened by controller, oxygen content in fuel tank is reduced, until in fuel tank oxygen concentration lower than preset lower limit or closed chamber in oxygen concentration time, controller is by closed electromagnetic valve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by the vehicle exhaust of low oxygen amount is introduced automotive oil tank, to make in fuel tank oxygen content gas reduce, when lack one of blast necessary condition namely oxygen time, blast is difficult to occur, thus realizes the explosion prevention function of motor vehicle oil tank.Explosion protection structure of the present utility model is simple, easy to use, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the explosion protection for motor vehicle oil tank.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, explosion protection for motor vehicle oil tank of the present utility model, comprise fuel tank 1 and be located at choker relief valve 2 and the steam cock 3 on fuel tank 1 surface, it is characterized in that, casing 4 is covered with on fuel tank 1 surface, closed chamber 5 is formed between casing 4 and fuel tank 1, choker relief valve 2 and steam cock 3 are all positioned at closed chamber 5, controller 6 and the first oxygen measurement probe 7 is provided with in closed chamber 5, in closed chamber 5 fuel tank surface on have some pores, each pore is sealed and installed with an electromagnetic valve 8, the second oxygen measurement probe 9 is equipped with in fuel tank 1 inside, controller 6 respectively with the first oxygen measurement probe 7, second oxygen measurement probe 9 and each electromagnetic valve 8 connect, casing 4 is communicated with automobile tail pipe 11 by pipeline 10.
Explosion protection of the present utility model, can vehicle exhaust extremely low for level of oxygen be introduced in closed chamber 5, two oxygen measurement probes 9 and 7 real-time oxygen concentration detected in fuel tank 1 and in closed chamber 5 respectively, and by the information feed back of detection to controller 6, when detecting that the oxygen concentration in fuel tank is higher than the higher limit preset and higher than in closed chamber during oxygen concentration, Controlling solenoid valve 8 is opened by controller 6, fuel tank and closed chamber both sides gas communicate, oxygen content in fuel tank is reduced, until in fuel tank oxygen concentration lower than preset lower limit or closed chamber in oxygen concentration time, electromagnetic valve 8 is closed by controller 6.
Device of the present utility model is by the level of oxygen in control fuel tank thus realization is effectively explosion-proof, and structure is simple, easy to use, safe and reliable.
