Abstract
The utility model provides an anti-reversal valve, which relates to the structure technology of a fluid valve, in particular to a valve structure used in the fuel supply system of an automobile fuel tank. A valve inner cover is transversely arranged in a valve body, an upper cavity and a lower cavity are respectively arranged at the upper side and the lower side of the valve inner cover, gas passages are respectively arranged in the upper cavity and the lower cavity, the valve inner cavity is provided with a valve port which communicates the upper cavity with the lower cavity, and the upper side of the valve port is provided with a valve bonnet which is connected to the upper end of the valve body. The inner bottom of the lower cavity is supported with a floater through a spring, the upper end of the floater is hinged with a valve clack at one side, and the valve clack is arranged under the lower end surface of the valve port. The anti-reversal valve is assembled on the oil pump flange of an automobile fuel system, when the side tumbling happens to a vehicle body, the floater moves to the valve port, and the valve plate thereon blocks at the valve port, so as to prevent the oil in the oil tank from flowing out when the vehicle has side tumbling. The anti-reversal valve has the advantages that the structure is simple, the production and the assembly are convenient, the driving safety of the vehicle can be improved, the security of the fuel supply system is ensured, and an exposition is avoided.
Description
Technical field
The utility model relates to a kind of structure technology of liquid valve, especially for the valve arrangement of the oil supply system of fuel tank of vehicle.
Background technique
Unimpeded in order to guarantee the fuel tank of vehicle fuel feeding, on fuel tank, be provided with weight valve, this weight valve mainly is made up of the spool of valve body and Qi Nei, when rollover appears in car body, flow out certainly in the car oil in the fuel tank, can cause very big potential safety hazard, sometimes, also can cause the person and property safety.Though existing part safety valve, because complex structure is difficult to produce inconvenient as installed, use.
The model utility content
When the utility model purpose is to design the rollover of a kind of car body, the anti-valve that turns over that oil can not flow out automatically in the fuel tank.
The utility model is cross setting valve inner cap in valve body, upper and lower two cavitys are set in that the valve inner cap is upper and lower respectively, in upper and lower two cavitys, gas channel is set respectively, in valve, cover the valve port that is communicated with upper and lower two cavity gas channels is set, arrange bonnet above valve port, described bonnet is connected the upper end of valve body.At the inner bottom part of lower chamber, support a float by spring, one side is hinged a valve block in the upper end of float, and described valve block is arranged in the below, lower end surface of valve port.
The utility model is assemblied on the vehicle fuel system Oil pump flange, and when the car body rollover occurring, float is to the valve port displacement, and the valve block retaining on it is at the valve port place, and oil flows out from fuel tank when preventing to overturn.The utility model is simple in structure, be convenient to produce, assembling, and the Security that can improve vehicle driving ensures oil supply system safety, avoids setting off an explosion.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Cross setting valve inner cap 2 in valve body 1 is provided with upper and lower two cavity A, B respectively in that valve inner cap 2 is upper and lower, in upper and lower two cavity A, B gas channel is set respectively, and the valve port 3 that is communicated with upper and lower two cavity gas channels is set on valve inner cap 2.Arrange bonnet 4 above valve port 3, bonnet 4 is connected the upper end of valve body 1.
At the inner bottom part of lower chamber B, support a float 6 by spring 5, a side is hinged a valve block 7 in the upper end of float 6, and valve block 7 is arranged in the below, lower end surface of valve port 3.
Claims (1)
1, the anti-valve that turns over, comprise valve body, cross setting valve inner cap in valve body, upper and lower two cavitys are set in that the valve inner cap is upper and lower respectively, in upper and lower two cavitys, gas channel is set respectively, in valve, cover the valve port that is communicated with upper and lower two cavity gas channels is set, above valve port, arrange bonnet, described bonnet is connected the upper end of valve body, it is characterized in that inner bottom part at lower chamber, support a float by spring, one side is hinged a valve block in the upper end of float, and described valve block is arranged in the below, lower end surface of valve port.
