All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the ship checks the tightness of the pipeline system or the valve under the condition that the pipeline system is complete, the pressure test needs to be carried out on the pipeline. Before the pressure testing, must use the instrument of suppressing to the pipeline, and current equipment generally exerts pressure to it through hand pump or compressed air pipe in the middle of the construction operation, wastes time and energy, and simultaneously, current equipment can only exert pressure to valve under single system pipeline or the same pressure, has the lower problem of practicality. The scheme provides a pressure distribution system, can meet the pressure requirements of different pipelines, outputs different pressure values, and has the advantages of saving time and improving efficiency. The specific scheme is as follows:
referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the present invention.
A pressure distribution system comprises a control unit, a hydraulic output oil path and at least two groups of shunt output oil paths. The hydraulic output oil path comprises a hydraulic pump 1; the shunt output oil path comprises a remote control valve 2 and a pressure sensor 3 which are arranged in sequence, and the remote control valve 2 is connected with the hydraulic pump 1; the hydraulic pump 1, the remote control valve 2 and the pressure sensor 3 are all electrically connected with the control unit.
In the present embodiment, 5 sets of the branch output oil paths are provided, and the remote control valves 2 of each set of the branch output oil paths are connected to the hydraulic pump 1.
The remote control valve 2 has the working principle that the spring force is larger than the normal pressure (the pressure value selected in advance) of the medium acting on the valve core, the valve core is in a closed state, when the pressure of the medium in the pipe exceeds the allowable pressure, the spring is compressed, the valve core is separated from the valve seat, the valve is automatically opened, the medium is discharged out of the valve, when the pressure returns to the normal value, the spring pressure pushes the valve core to the valve seat again, and the valve is automatically closed.
Illustratively, when the distribution system is used, a pressure value required by each component flow output oil path needs to be preset in advance to the control unit, the pressure value is a working pressure value of the remote control valve, then the hydraulic pump 1 can be started through the control unit, when the hydraulic pump 1 works, the pressure value of the shunt output oil path gradually rises, when the pressure borne by the remote control valve 2 reaches the preset pressure value, the remote control valve 2 is conducted, and at the moment, the pressure sensor 3 on each shunt output oil path feeds back a real-time pressure value to the control unit in real time, so that different pressure distribution processes are realized. In this embodiment, a hydraulic output oil circuit can 5 component flow output oil circuit of stable control, satisfies 5 pipeline pressure testing work, to the required pressure requirement of different pipelines, exports different pressure size, has the advantage of saving time, raising the efficiency, and it has high use practicality and use flexibility.
