the bottom end of the valve body is sealed by a bottom cover, the floater is arranged in the inner cavity of the valve body, the density of the floater is smaller than that of fuel oil, the outer diameter of the floater is smaller than the inner diameter of the inner cavity of the valve body, and the bottom of the floater is connected with the bottom cover through a lower spring;
the top of valve body is sealed with the upper cover, and the top of upper cover is equipped with the exhaust hole, the bottom face of exhaust hole is equipped with the retaining ring, be equipped with the pressure release ball in the exhaust hole, the external diameter of pressure release ball is less than the aperture of exhaust hole just is greater than the aperture of retaining ring, thereby the top of pressure release ball supports through last spring the top of exhaust hole, thereby the hoop is equipped with the clamping ring on the lateral surface of upper cover fixes the top at the valve body with the upper cover, the upper portion of valve body inner chamber is equipped with sealing fin and block by supreme down in proper order, the sealing fin locates the upper portion of float and seals the valve body inner chamber, thereby the top at the valve body inner chamber is fixed to the sealing fin in the top of sealing fin is supported to the bottom of block upper portion and block.
The car dumper with the safety valve is characterized in that: the outer diameter of the floater is 75-95% of the inner diameter of the inner cavity of the valve body, and the outer diameter of the pressure relief ball is 75-95% of the aperture of the vent hole.
The utility model relates to a car dumper valve integrated with an overpressure protection valve, which simplifies the structure of a fuel filling cover and simultaneously saves the cost. The exhaust hole on decompression ball and the last spring cooperation upper cover constitutes the overvoltage protection valve structure, and its overvoltage protection exhaust passage is independent of outside the main exhaust passage, and the decompression ball seals the exhaust hole under the thrust effect of last spring under the normal operating mode, and this exhaust passage is normally closed passageway, and when the valve main passage can't exhaust because unusual reason, after the oil tank internal pressure exceeded the prescribed value, the decompression ball was pushed away the exhaust hole bottom, and the overvoltage protection exhaust passage was opened, realizes the exhaust function, ensures that the oil tank is in safe operation environment.
The utility model has the following beneficial effects: simple structure, good sealing performance, simplified structure, safety and reliability and cost saving.

Detailed Description
The utility model is further illustrated by the following specific examples.
Examples
The utility model provides a rollover valve with relief valve, includes valve body 1, snap ring 2, upper cover 3, float 4, sealing washer 5, lid 6, bottom 7, lower spring 8, pressure release ball 9 and last spring 10, as shown in figure 1, and specific structure is:
the valve body 1 is in a tubular shape with a through middle part, the bottom end of the valve body 1 is closed by a bottom cover 7, the float 4 is arranged in the inner cavity of the valve body 1, the density of the float 4 is smaller than that of fuel, the outer diameter of the float 4 is smaller than the inner diameter of the inner cavity of the valve body 1, and the bottom of the float 4 is connected with the bottom cover 7 through a lower spring 8;
the top of valve body 1 is sealed with upper cover 3, and the top of upper cover 3 is equipped with the exhaust hole, the bottom surface of exhaust hole is equipped with the retaining ring, be equipped with pressure release ball 9 in the exhaust hole, the external diameter of pressure release ball 9 is less than the aperture of exhaust hole just is greater than the aperture of retaining ring, thereby the top of pressure release ball 9 supports through last spring 10 the top of exhaust hole, thereby hoop on the lateral surface of upper cover 3 establishes snap ring 2 and fixes upper cover 3 on the top of valve body 1, and the upper portion of valve body 1 inner chamber is equipped with sealing washer 5 and block 6 from bottom to top in proper order, and sealing washer 5 locates the upper portion of float 4 and seals valve body 1 inner chamber, and block 6 inlays to be established and fix the upper portion in valve body 1 inner chamber and the top surface of sealing washer 5 is supported to the bottom of block 6 thereby fixes sealing washer 5 on the upper portion in valve body 1 inner chamber.
