The oil drain valve of the recovery oil storage box for the motor vehicle oil tank is characterized in that: the lower part of the oil drain hole is in a truncated cone shape, the cross section of the truncated cone shape is gradually increased from top to bottom, and the top end of the plug is in a truncated cone shape matched with the lower part of the oil drain hole.
The use method of the recovery oil storage box oil drain valve for the motor vehicle oil tank is characterized by comprising the following steps of: the method comprises the following steps of:
closing the valve body: the shell is sleeved outside the valve body and then is arranged at the bottom of the oil storage box, when the oil storage box is hollow, the sealing piece drives the plug to push upwards into the oil drain hole of the valve body under the action of spring force to enable the valve body to be closed, and the state can optimize the sealing performance of the oil tank and reduce the emission of oil gas;
recovering fuel oil: when the fuel gradually escapes from the protruding pipe to the oil storage tank at one side of the floater, the total weight of the floater increases to press down the spring, the floater presses down the sealing piece to separate the plug from the oil drain hole so as to open the valve body, and then the fuel in the oil storage tank is recovered;
closing the valve again: after the fuel oil in the oil storage tank is used, the total weight of the floater is reduced, and the sealing sheet drives the plug to upwards push into the oil drain hole of the valve body under the action of the elastic force of the spring so as to close the valve body again.
The invention has the following beneficial effects: simple structure, convenient to use, the leakproofness is good, reduces fuel loss.
Drawings
Fig. 1 is a front view in cross section of the present invention.
Detailed Description
The invention is further illustrated by the following specific examples.
Example 1
