[0006] When the present application is in use, the amount of liquefied gas entering the branch pipeline is controlled by the first valve and the second valve, and is observed by the flow meter at the same time, and the excess liquefied gas flows along the main pipeline to the connecting pipe, and is pressurized by the pressure pump and the squeezed liquefied gas is filled into the liquefied gas tank through the gas outlet pipe.

[0007] Preferably, the outlet end of the connecting pipe is connected to the inlet end of the three-way valve, and the two outlet ends of the three-way valve are connected to the outlet pipes respectively. The three-way valve can ensure that when one outlet pipe is inletting air, the other outlet pipe is in a closed state, thereby ensuring that there is always one side to inlet air into the liquefied gas tank, and then ensuring that when one liquefied gas tank is sealed, the other outlet pipe is still in an outlet state, achieving continuous inflation and improving work efficiency.

The hinged connection of the right annular plate can not only facilitate the placement of the liquefied gas tank between the left annular plate and the right annular plate, but also after the right annular plate surrounds the left annular plate and the plug rod is inserted into the slot, the left annular plate and the right annular plate can position the liquefied gas tank, making it convenient for the conveyor belt to drive the liquefied gas tank.

[0010] Preferably, the rotating shaft of the three-way valve is sleeved with a driven sprocket, a driving motor is fixedly arranged on one side of the driven sprocket, the rotating shaft of the driving motor is sleeved with a driving sprocket, and the driving sprocket and the driven sprocket are driven by a chain. The rotation of the rotating shaft of the driving motor can drive the rotation of the driving sprocket, and then drive the rotation of the driven sprocket through the chain, and the rotation of the driven sprocket drives the rotation of the rotating shaft of the three-way valve, thereby eliminating the need to manually rotate the rotating shaft to adjust the valve opening position.

[0011] The beneficial effects of the present utility model are as follows: the use of the present application can not only extract the light component of the liquefied gas in the stable part, but also store the extracted liquefied gas in the liquefied gas tank for storage and sale, thereby reasonably utilizing the excess liquefied gas and reducing waste; at the same time, through the three-way valve and the two air outlet pipes, one can seal the liquefied gas tank while the other one can inflate the liquefied gas tank, thereby avoiding the need to shut down the delivery gas when sealing the liquefied gas tank, thereby improving the filling efficiency.

[0018] A hydrogenation product liquefied gas delivery system, such as Figure 1 and Figure 2 As shown. It includes a main pipeline 1 connected to the reflux tank, the main pipeline 1 is sequentially connected with a branch pipeline 2 and a connecting pipe 3 along the gas connection direction, the gas outlet end of the connecting pipe 3 is connected with one end of the gas outlet pipe 4; the branch pipeline 2 is connected with the stabilization tower reflux pump, and a flow meter 5 and a first valve 6 are arranged on the branch pipeline 2; the connecting pipe 3 is sequentially provided with a second valve 7 and a booster pump 8, and the other end of the gas outlet pipe 4 is detachably connected and connected with the liquefied gas tank.

[0019] When the present application is in use, the amount of liquefied gas entering the branch pipe 2 is controlled by the first valve 6 and the second valve 7, and is observed by the flow meter 5, while the excess liquefied gas flows along the main pipe 1 to the connecting pipe 3, and is pressurized by the pressure pump 8 so that the squeezed liquefied gas is filled into the liquefied gas tank through the gas outlet pipe 4. Thus, not only can the light components of the liquefied gas be extracted at the stable part, but the extracted liquefied gas can also be stored in the liquefied gas tank for storage and sale, thereby making reasonable use of the excess liquefied gas and reducing waste.

[0020] The outlet end of the connecting pipe 3 is connected to the inlet end of the three-way valve 9, and the two outlet ends of the three-way valve 9 are respectively connected to the outlet pipe 4. The three-way valve 9 can ensure that when one side of the outlet pipe 4 is inlet, the other side of the outlet pipe 4 is in a closed state, thereby ensuring that there is always one side to inlet gas into the liquefied gas tank, and then ensuring that when one side of the liquefied gas tank is sealed, the other side of the outlet pipe 4 is still in the outlet state, achieving continuous inflation and improving work efficiency.

[0021] A conveying device is provided below the air outlet pipe 4. The conveying device includes a conveyor belt 10 and a conveyor motor driving the conveyor belt 10 for conveying. Several positioning devices are evenly provided on the conveyor belt 10 along the conveying direction. The liquid level gas tank is arranged on the conveyor belt 10 through the positioning device.

A slot for the plug rod 14 to be inserted is provided on the top surface of the right annular plate 12.

[0022] The right annular plate 12 is hingedly connected, which not only facilitates the placement of the liquefied gas tank between the left annular plate 11 and the right annular plate 12, but also after the right annular plate 12 surrounds the left annular plate 11 and inserts the insertion rod 14 into the slot, the left annular plate 11 and the right annular plate 12 can hold the liquefied gas tank in place, making it convenient for the conveyor belt to drive the liquefied gas tank, and the conveyor belt 10 can drive the liquefied gas tank to move, eliminating the need for the tooling personnel to manually move the filled liquefied gas tank out, and the tooling personnel only need to hold the upper part of the liquefied gas tank by hand.
