Description

Technical Field

[0001] This utility model relates to the field of recoiler maintenance equipment, and in particular to rapid gas and liquid injection equipment. Background Technology

[0002] The recoil mechanism of artillery needs to be inspected regularly, or tested and repaired after a malfunction. Currently, most of the inspection and repair work involves nitrogen cylinders and foot-operated or hand-operated injection guns for testing, replenishing gas and liquid. First, the internal pressure is checked. If the pressure is low, nitrogen is added using the gas injection tool. If the liquid is low, liquid is added using the liquid injection tool. Inspection, gas replenishment, and liquid replenishment involve three sets of equipment that are constantly being replaced, resulting in very low efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rapid gas and liquid injection device that integrates liquid injection and gas injection together, eliminating the need to change tools midway, thus making it more efficient and convenient.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a rapid gas and liquid injection device, including a liquid injection cylinder, a nitrogen source, a first reversing valve and a second reversing valve;

[0005] The injection cylinder has an air inlet and a liquid outlet at its two ends. The air inlet is provided with an air inlet, and the liquid outlet is provided with a liquid outlet and a liquid inlet. The liquid inlet is provided with a liquid inlet valve. A piston and a spring are provided inside the injection cylinder. The spring pushes the piston to slide towards the air inlet.

[0006] The nitrogen source is connected to the inlet of the first reversing valve, the first outlet of the first reversing valve is connected to the air inlet, the second outlet of the first reversing valve is connected to the first inlet of the second reversing valve, the second inlet of the second reversing valve is connected to the liquid outlet, and the outlet conversion tool of the second reversing valve is connected to the air nozzle.

[0007] In use, the second reversing valve is connected to the gas nozzle of the re-entry machine via a conversion tool. The pressure monitoring tool built into the conversion tool is used to detect the pressure inside the re-entry machine. When gas needs to be added, the inlet of the first reversing valve is connected to the second outlet, and the second inlet of the second reversing valve is connected to the outlet. At this time, the nitrogen source can directly bypass the liquid injection cylinder to add gas to the re-entry machine. When liquid needs to be added, first open the liquid inlet valve, and the liquid is injected into the liquid injection cylinder. Then connect the inlet of the first reversing valve to the first outlet, and the first inlet of the second reversing valve to the first outlet. The nitrogen source gas enters the liquid injection cylinder from the gas inlet, pushing the piston. The piston pushes the liquid in the liquid injection cylinder out of the liquid outlet and injects it into the re-entry machine. The liquid and gas paths are supplied separately and transported to the re-entry machine through a unified pipeline. There is no need to change the liquid injection or gas injection equipment, making the whole process more efficient and convenient.

[0008] Preferably, the air inlet is provided with a vent, and the vent is provided with a vent valve. This facilitates the release of air from the inner wall near the air inlet to allow the piston to move.

[0009] Preferably, the air inlet is located on the side wall of the injection cylinder to facilitate air release.

[0010] Preferably, the liquid inlet is located on the side wall of the injection cylinder, which facilitates the injection of liquid into the injection cylinder.

[0011] Preferably, the injection cylinder, the first reversing valve, and the second reversing valve are rigidly connected to each other, forming a single integrated structure for easy portability.

[0012] Preferably, the second outlet of the first directional control valve is connected to the first inlet of the second directional control valve via a direct connection pipe, so as to connect the first directional control valve and the second directional control valve.

[0013] Preferably, the direct connection pipe is made of metal. This improves the stability of the relative position of the first and second directional valves.

[0014] Preferably, the spring is located between the piston and the liquid outlet end, facilitating the pushing of the piston towards the air inlet end.

[0015] The beneficial effects of this utility model are:

[0016] This solution integrates liquid injection and gas injection, eliminating the need to change tools midway, making it more efficient and convenient. Attached Figure Description

The liquid inlet is equipped with an inlet valve 9. A piston 3 and a spring 2 are installed inside the injection cylinder 1. The spring 2 pushes the piston 3 to slide towards the air inlet end. The nitrogen source 6 is connected to the inlet of the first reversing valve 4. The first outlet of the first reversing valve 4 is connected to the air inlet. The second outlet of the first reversing valve 4 is connected to the first inlet of the second reversing valve 5. The second inlet of the second reversing valve 5 is connected to the liquid outlet. The outlet conversion tool 7 of the second reversing valve 5 is connected to a gas nozzle.

[0026] The liquid inlet is located on the side wall of the injection cylinder 1, which facilitates the injection of liquid into the injection cylinder 1.

[0027] The injection cylinder 1, the first reversing valve 4, and the second reversing valve 5 are rigidly connected to each other, forming a single integrated structure for easy portability.

[0028] The second outlet of the first directional valve 4 is connected to the first inlet of the second directional valve 5 via a direct connection pipe, so as to connect the first directional valve 4 and the second directional valve 5.

[0029] The direct connection pipe is made of metal. This improves the stability of the relative position of the first reversing valve 4 and the second reversing valve 5.

[0030] The spring 2 is located between the piston 3 and the liquid outlet end, facilitating the pushing of the piston 3 towards the air inlet end.
