Abstract
The utility model relates to a compound air inlet-exhaust valve for an automobile fuel tank, composed of a valve cap (1), a filter sheet (2), a support (3), an air exhaust valve sheet (4), a valve seat (5), an air inlet valve sheet (6), and a valve body (7). The utility model uses one valve, and uses the technical method that the valve sheets and the valve seat are provided with air ventilating holes to realize the air inlet-exhaust purpose. The utility model uses one combined valve to replace two one-way valves, which simplifies the structure of a fuel tank, and lowers the cost of an automobile. The utility model is provided with the filter sheet, which purifies air, and guarantees the favorable working performance of the valve. Meantime, the valve cap is additionally provided with a short joint, which ensures that the testing method of the whole valve is simple and convenient, and enhances work efficiency.
Description
Belong to the valve class, relate to and be used to regulate the fuel tank of vehicle internal pressure, and realize the dual-purpose valve of air inlet or exhaust.
At present, safe reliability and sealing requirements to the right fuel tank of bogie are more and more stricter, for regulating the balance of the fuel tank internal pressure after sealing, the light truck that China goes into operation the nineties adopts and make two interfaces on fuel tank, one taps into air valve, another air valve that runs in has replaced original exhaling hole structure.Above-mentioned inlet and outlet valve all is a single structure, special purpose, and air inlet valve does not have air-filtering arrangement, and dust is stuck between the inlet valve seat easily or enters fuel tank, influences the response pressure of air inlet valve and the cleanliness level of oil.In addition, the valve gap that this advances or blow off valve leads to atmosphere one end does not have adaptor union, when the response pressure of testing valve, also must just can carry out by special holding device.
The purpose of this utility model: (one) will provide a kind of both can realize air inlet, can realize the dual-purpose combined type valve of exhaust again, thereby replaced two check valves, reduced auto cost; (2) to solve the air filtration problem of air inlet, guarantee the good quality and the serviceability of valve.
Technical conceive of the present utility model is: (one) uses for reference the principle of air inlet and blow off valve, and the intake and exhaust valve block is fixed on the valve seat both sides, can freely pass through for making atmosphere, and reach air inlet.The purpose of exhaust is provided with air extractor vent in the edge of exhaust valve plate and valve seat, and this hole is sealed by the air-intake valve plate on opposite side (opposite); Equally, in the edge of air-intake valve plate and valve seat air extractor vent is set also, this hole is sealed by the exhaust valve plate of opposite side, and the number in hole is decided on the material and the physical dimension of valve block, but advances.Air extractor vent on the exhaust valve plate will keep certain angular displacement mutually, guarantees sealing relatively, and the number of valve seat upper vent hole is the summation of the number in hole on air-intake valve plate and the exhaust valve plate.(2) for realizing the purpose of air filtration, at induction opening one end a filter is set, it is attached on the support that has through hole.(3) for making things convenient for the test of response pressure, the utility model has been set up a source nipple with valve gap.
The structural representation of embodiment of the present utility model is provided by Fig. 1, and it is by valve gap (1).Filter (2), support (3) exhaust valve plate (4), valve seat (5), air-intake valve plate (6), valve body (7) is formed; Constitute with valve body (7) by valve gap (1), the cavity volume of exhaust, the gas that this chamber can make into or discharge obtains buffering at this, the chance of step-down, the atmosphere that sucks filters and purifies by filter (2), guarantee the cleanliness level of fuel oil, support (3) plays support filter (2) and compresses valve seat (5), air-intake valve plate (6) and exhaust valve plate (4) are being fixed in the both sides of valve seat (5), advance, exhaust valve plate is a vitals of realizing intake and exhaust, it will guarantee to reach unlatching in the range of pressure of regulation, and the number in its physical dimension and hole is all determined through the test of strictness.Advancing of present embodiment, the exhaust valve plate structure is provided by Fig. 2 and Fig. 3, and Fig. 2 is a front view, and Fig. 3 is a left view.Valve block adopts the elastomeric material compacting to form, the air extractor vent that the edge is provided with 3 five equilibriums communicates with the air extractor vent of 6 five equilibriums on the valve seat respectively, during assembling, advance, angular displacement between the exhaust valve plate upper vent hole is 180 degree (see figure 1)s, principle of work of the present utility model: the lengthening joint and the fuel tank of valve are connected, short circuit head leads to atmosphere, atmosphere is from three through holes of valve block (4) when the reduction of the minimizing of fully enclosed fuel tank internal cause oil mass or outside air temperature and when producing negative pressure, the pressure that gives that overcomes air-intake valve plate (6) opens it, oil-feed tank is just closed until the internal and external pressure balance air-intake valve plate.Otherwise, when outside air temperature increase or fuel tank because of impact endurance test shock cubic expansion suddenly or produce oil gas, when the fuel tank internal pressure surpasses regulation, high pressure gas in the fuel tank enters 3 through holes of valve pocket by air-intake valve plate (6), make exhaust valve plate (4) overcome precompressed compression and open, high pressure gas is through filter disc (2) exhaust to atmosphere, until internal and external pressure balance, exhaust valve plate (4) overcomes and gives pressure and open, high pressure gas is through filter disc (2) exhaust to atmosphere, until internal and external pressure balance, exhaust valve plate (4) side closes.
Effect of the present utility model: (one) adopts a valve, by the technological means of passage is set at valve block and valve seat, realized the purpose of air inlet and exhaust, two check valves have been replaced by a combination valve, simplified the structure of fuel tank, reduced the cost of automobile, (two) are provided with filter, purify air, guaranteed the works fine performance of valve. (3) set up short circuit head at valve gap, the test that makes whole valve is simple and direct and make things convenient for, and has improved work efficiency.
The utility model has enough cavity volumes, is not only applicable to the fuel tank of light truck, also is suitable for applying at jumbo fuel tank or diesel oil tank.
