[0002] At present, during the daily inspection of gas stations, it is necessary to regularly open the oil measuring port to measure and check the oil storage amount in the tank, test the water content with water test paste, etc. However, since the oil tank will produce volatile oil and gas during daily storage and operation, thereby generating a large gas pressure, when the operator opens the ball valve and sealing cover at the oil measuring port, the volatile gas gushes out under the action of pressure. First, the volatile oil vapor will cause safety hazards. Second, it will pollute the environment and cause great harm to the health of personnel. Third, the volatilization of oil and gas causes a huge waste of energy. Based on the above three points, it is necessary to design and modify the oil measuring port ball valve with as little modification as possible in order to meet the use requirements.

The manhole well 1 of an oil tank in a gas station generally comprises a large flange of the oil tank, an oil inlet pipeline, an oil delivery pipeline, a liquid level meter system, an oil metering pipeline 2, etc., wherein the oil metering pipeline 2 comprises: a straight pipe section, an oil measuring port ball valve 3 and a ball valve sealing flap 4. The bottom of the straight pipe section is connected to the large flange, the oil measuring port ball valve 3 is installed on the straight pipe section, one end of the ball valve sealing flap 4 is hinged to the upper part of the straight pipe section, and the other end of the ball valve sealing flap 4 is locked with the straight pipe section by a locking member 7.

[0025] The utility model is an auxiliary device for measuring oil products in an oil tank of a gas station, comprising an oil and gas recovery pipe 5 for cooperating with a ball valve sealing flap 4 and an oil and gas recovery box 6 for cooperating with the oil and gas recovery pipe 5. The oil and gas recovery pipe 5 is used to guide and recover the volatilized oil and gas when measuring oil products. The oil and gas recovery box 6 is used to communicate with the oil and gas recovery pipe 5 to store the recovered oil and gas to prevent it from volatilizing again. Specifically:

[0026] An air inlet 11 is provided on one side of the oil and gas recovery box 6, and a gas bottle 9 is installed in the oil and gas recovery box 6, one end of the oil and gas recovery pipe 5 is connected to the air outlet 8 provided on the ball valve sealing flap 4, and the other end of the oil and gas recovery pipe 5 is connected to one end of the air inlet 11, and the bottle mouth of the gas bottle 9 is connected to the other end of the air inlet 11, so that the gas bottle 9 and the ball valve sealing flap 4 can be connected through the oil and gas recovery pipe 5, which is convenient for using the gas bottle 9 to store and recover the volatilized oil and gas, and in order to prevent the oil and gas entering the gas bottle 9 from escaping again, a one-way check valve 13 is also installed at the bottle mouth of the gas bottle 9, preferably, a gas adsorbent 14 is also provided in the gas bottle 9, and further preferably, the gas adsorbent 14 is activated carbon.

[0027] In order to facilitate the replacement operation of the gas cylinder 9, an opening for taking and placing the gas cylinder 9 is provided on the other side of the oil and gas recovery box, and the opening is sealed by a bottom cover 12. Preferably, the bottom cover 12 is threadedly connected to the oil and gas recovery box 6, and an internal thread is provided on the bottom cover 12, and an external thread matching the internal thread is provided on the oil and gas recovery box 6 at the opening.

[0028] In order to facilitate the rapid disassembly and assembly of the oil and gas recovery pipe 5, gas pipeline quick connectors 10 are installed at both ends of the oil and gas recovery pipe 5; in order to ensure the sealing of the connection between the gas storage bottle 9 and the air inlet 11, a sealing ring for cooperating with the air inlet 11 is also installed at the bottle mouth of the gas storage bottle 9; at the same time, the oil and gas recovery pipe 5 is an anti-static and oil-corrosion-resistant hose, which is not only strong and durable, but also can always maintain the connection between the ball valve sealing flap 4 and the oil and gas recovery box 6 when bent and folded, which is convenient for cooperating with the opening and closing operation of the ball valve sealing flap 4, and is also convenient for moving the oil and gas recovery box 6 to replace the gas storage bottle 9.

[0029] In actual use, the oil and gas recovery box 6 and the gas storage bottle 9 are both cylindrical.

[0030] The specific use process of the oil product metering auxiliary device for oil tanks in gas stations provided by the utility model is as follows:

[0031] Before metering, the oil-measuring port ball valve 3 and the ball valve sealing flap 4 are both closed and locked to prevent oil and gas from volatilizing outward from the oil metering pipeline 2. During metering, the ball valve sealing flap 4 is kept closed first, and then the oil-measuring port ball valve 3 is opened. The volatilized oil and gas escape outward from the oil metering pipeline 2 through the oil-measuring port ball valve 3 under pressure. Due to the obstruction of the ball valve sealing flap 4, the volatilized oil and gas enter the oil and gas recovery pipe 5 through the air outlet 8 on the ball valve sealing flap 4, and then enter the gas storage bottle 9 through the air inlet 11 of the oil and gas recovery box 6. After being adsorbed by the activated carbon in the gas storage bottle 9, it is stored. A one-way check valve 13 is arranged at the bottle mouth of the gas storage bottle 9, so that the gas entering the gas storage bottle 9 cannot escape. At the same time, the bottom cover 12 of the oil and gas recovery box 6 can be unscrewed to facilitate the replacement of the gas storage bottle 9.

[0032] After the volatilized oil and gas enter the gas storage bottle 9 under high pressure, the air pressure in the oil storage tank drops. At this time, the ball valve sealing flap 4 can be opened to measure oil or test water. Because the pressure in the oil storage tank drops, the risks of safety, escape, pollution, etc. caused by the oil and gas spraying are reduced, which not only ensures safety, but also avoids the waste of energy caused by the volatilization of oil and gas as much as possible.
