Referring to fig. 1, fig. 1 is a schematic structural diagram of the device for preventing oil and gas from escaping during refueling and metering of a refueling machine according to the present invention. The utility model provides an oiling machine adds oil measurement and prevents oil gas escape device, includes metering tank 1, and metering tank 1's top is equipped with the opening, and metering tank 1's top is equipped with and is used for sealing open-ended upper cover 2, has seted up tank filler hole 3 on the upper cover 2, is equipped with round elastic layer 4 in the tank filler hole 3.

Metering tank 1 is current device, metering tank 1 is including a jar body, a jar body is equipped with the cone by a top, the bottom is equipped with down the cylinder of cone and constitutes, jar body bottom is fixed through the installing support, the cone bottom is the leakage fluid dram down, be used for connecting oil discharge pipe, leakage fluid dram department is equipped with the drain valve, the inclined plane bottom of going up the cone is equipped with two mutually perpendicular's tubulose spirit levels along the horizontal plane, the installing support bottom is equipped with the leveling stabilizer blade, be used for 1 leveling of metering tank, it is connected with the overflow cover through the measurement neck to go up cone top opening part, overflow cover open-top, and the top inwards buckles the extension and forms cyclic annular. The upper cover 2 is arranged at the top end of the overflow cover. A liquid level pipe made of transparent glass is communicated between the overflow cover and the upper cone, and a vernier caliper for measuring the liquid level is arranged on one side of the liquid level pipe; the vernier of the vernier caliper is provided with a transparent reading ring surrounding the liquid level pipe, and the transparent reading ring is horizontally provided with a central reading line for tracking the concave surface of the liquid level in the corresponding liquid level pipe.

When the oiling machine is checked, firstly, the metering tank 1 is well grounded, trial operation is carried out according to the method of the verification regulation of JJJG 443-2015 Fuel oiling machine, the metering tank 1 is in a preparation state, the metering tank 1 is leveled by matching a tubular level with leveling support legs, the metering tank 1 is well grounded, a fuel gun is extracted, the oiling machine is started, an indicating device of the oiling machine returns to zero, the fuel gun is inserted into a fuel filling hole 3, and due to the fact that the elastic layer 4 has contractibility, under the condition that the fuel filling hole 3 is inserted into the fuel gun, the elastic layer 4 can automatically rebound, the fuel gun is wrapped by the elastic layer 4, the sealing performance between the fuel gun and the upper cover 2 is good, air flowing is isolated, and volatilization of fuel injected into the metering tank 1 is avoided.
