[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0026] Reference Figure 1-Figure 4The oil and gas recovery refueling gun with ORVR function provided by the utility model comprises a gun body 1, an oil and gas recovery channel 101 arranged in the gun body 1, an ORVR valve 2 arranged on the oil and gas recovery channel 101, an oil circuit 102 arranged in the gun body 1, a main oil circuit valve 3 arranged on the oil circuit 102 and a wrench 4 arranged on the gun body 1. The main oil circuit valve 3 controls the on-off of the oil circuit 102 by the lifting and lowering of the valve stem 301 inside it. The wrench 4 can press the valve stem 301 to control its lifting and lowering. When the wrench 4 is pulled upward, the wrench 4 can drive the valve stem 301 to rise upward, thereby opening the oil circuit 102. After the wrench 4 is released, the wrench 4 no longer presses the valve stem 301, and the valve stem 301 automatically resets to disconnect the oil circuit 102. A sealing member 5 is slidingly arranged in the oil and gas recovery channel 101, and the on-off of the oil and gas recovery channel 101 is controlled by the sliding sealing member 5. The valve stem 301 is connected to the sealing member 5, and the sliding of the sealing member 5 is driven by the lifting and lowering of the valve stem 301. By utilizing the linkage function of the wrench 4 and the valve stem 301, the seal 5 is driven to control the opening and closing of the oil and gas recovery channel 101, replacing the original oil and gas valve, which can reduce the number and weight of the fuel gun parts, improve the service life and convenience, and at the same time, the ORVR valve is embedded in the position of the original oil and gas valve of the fuel gun to avoid interference of the ORVR valve during the refueling process.

[0027] like Figure 3 As shown, the seal 5 is sleeved on the valve stem 301 and fixedly connected thereto, and the valve stem 301 is raised upward to drive the seal 5 to move together, and to connect the oil and gas recovery channel 101. An annular rubber seal ring 501 is provided on the seal 5 to improve the sealing performance.

[0028] like Figure 1 and Figure 2 As shown, the front end of the gun body 1 is provided with an oil and gas sealing cover 6, and the inlet of the oil and gas recovery channel 101 extends into the oil and gas sealing cover 6. The oil and gas sealing cover 6 includes a telescopic sleeve 601 provided on the gun body 1 and a sealing sleeve 602 provided at the end of the telescopic sleeve 601. The end of the sealing sleeve 602 is an eccentric cross-section structure.

[0029] like Figure 4 As shown, when refueling a car tank without ORVR, the oil and gas in the tank first enter the oil and gas recovery channel 101 through the oil and gas sealing cover 6, and then reach the ORVR valve 2. The ORVR valve 2 controls the oil and gas recovery channels 101 on both sides to be connected, so that the oil and gas reach the seal 5. Since the seal 5 is moved under the pushing action of the wrench 4, the oil and gas recovery channels 101 on both sides of the seal 5 are connected, and the oil and gas are smoothly recovered through the secondary oil and gas recovery system along the remaining oil and gas recovery channels 101.

[0030] When refueling a car tank with ORVR, the ORVR valve 2 controls the oil and gas recovery channels 101 on both sides to be disconnected under the action of the external atmospheric pressure, thereby limiting the vacuum pump of the secondary oil and gas recovery system from extracting gas from the tank.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
