Abstract
Description
Technical Field
[0001] This invention belongs to the field of oil recovery and pressure relief technology, and specifically relates to an oil recovery and pressure relief device. Background Technology
[0002] During the cold spray test of a certain type of military product, the oil in the oil bottle is sprayed out under the pressure generated by the combustion of gunpowder. If effective measures are not taken in time to collect the sprayed semi-fluid oil, it will cause environmental pollution and pose a fire hazard. Furthermore, the combustion of gunpowder during the cold spray test generates significant pressure; if a pressure relief device is not implemented in time, it will endanger the operators. This paper proposes a rapid oil recovery and pressure relief device to solve the problems of rapid recovery of semi-fluid oil and pressure relief in the cold spray test procedure. The device is simple in structure, easy to operate, and safe to use. Summary of the Invention
[0003] The invention device achieves two functions: first, the elbow part (2) at the front end of the device is connected to the collection device (1), and the sprayed oil reaches the collection device (1) through the pressure relief pipe (4) and the elbow part (2), thereby realizing the rapid collection of the sprayed semi-fluid oil; second, the pressure relief pipe (4) of the device has a long structure and a large diameter, which can realize the rapid unloading of the pressure generated by the combustion of gunpowder. The outlet of the oil bottle (6) is sealed by a piston. The piston opens under the pressure generated by the combustion of gunpowder, and the oil passes through the oil outlet pipe (6) and reaches the pressure relief pipe (4) through the connecting hose (5). By changing from the small diameter oil outlet pipe to the large diameter pressure relief pipe (4), the pressure generated by the combustion of gunpowder is safely unloaded by the outlet of the pressure relief device, realizing the functions of simple and safe operation, convenient oil recovery, and rapid pressure relief.

[0006] The invention device achieves two functions: first, the elbow part (2) at the front end of the device is connected to the collection device (1), and the sprayed oil reaches the collection device (1) through the pressure relief pipe (4) and the elbow part (2), thereby realizing the rapid collection of the sprayed semi-fluid oil; second, the pressure relief pipe (4) of the device has a long structure and a large diameter, which can realize the rapid unloading of the pressure generated by the combustion of gunpowder. The outlet of the oil bottle (6) is sealed by a piston. The piston opens under the pressure generated by the combustion of gunpowder, and the oil passes through the oil outlet pipe (6) and reaches the pressure relief pipe (4) through the connecting hose (5). By changing from the small diameter oil outlet pipe to the large diameter pressure relief pipe (4), the pressure generated by the combustion of gunpowder is safely unloaded by the outlet of the pressure relief device, realizing the functions of simple and safe operation, convenient oil recovery, and rapid pressure relief.
