Abstract
The utility model relates to a kind of CNG hydraulic substation reversing arrangement.Total oil inlet pipe and total oil outlet tube communicate with first, second sealing joint of two position four-way valves respectively, oil inlet pipe is communicated with fuel tank by high-pressure service pump, oil outlet tube communicates with fuel tank, and the first oil distributing pipe and the second oil distributing pipe communicate with the 3rd, the 4th sealing joint of two position four-way valves.Its structure is simple, reliable, easy to maintenance.
Description
Technical field
The utility model belongs to a kind of hydraulics device of hydraulic substation, particularly a kind of CNG hydraulic substation reversing arrangement.
Background technique
At present, in the CNG air entraining substation prying body that on market, a lot of producer is used, the object that traditional oil-feed oil return uses 4 air operated reversing valves mutually to exchange to reach oil-feed and oil return.As shown in Figure 1, total filler opening is entered by direction as shown, is divided into two-way to be that A1, A2 pneumatic actuator opens and closes successively under the control of PLC respectively afterwards.Enter A pipeline and B pipeline.In like manner under the control of PLC, the hydraulic oil flowed back to by A pipeline and B pipeline enters respectively after B1 and B2 pneumatic actuator is aggregated into total return line and enters fuel tank.The shortcoming of the method is the more, uneconomical of pneumatic actuator use.Control complicated, go wrong and morely not easily to investigate.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of CNG hydraulic substation reversing arrangement.Its structure is simple, reliable, easy to maintenance.
The technical scheme in the invention for solving the technical problem is: total oil inlet pipe and total oil outlet tube communicate with first, second sealing joint of two position four-way valves respectively, oil inlet pipe is communicated with fuel tank by high-pressure service pump, oil outlet tube communicates with fuel tank, and the first oil distributing pipe and the second oil distributing pipe communicate with the 3rd, the 4th sealing joint of two position four-way valves.
The utility model structure is simple, reliable, easy to maintenance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is prior art schematic diagram;
Fig. 2 is the utility model schematic diagram.
Embodiment
As shown in Figure 2, total oil inlet pipe 1 and total oil outlet tube 2 communicate with first, second sealing joint of two position four-way valves 5 respectively, oil inlet pipe 1 is communicated with fuel tank (not shown in FIG.) by high-pressure service pump (not shown in FIG.), oil outlet tube 2 communicates with fuel tank, and the first oil distributing pipe 3 and the second oil distributing pipe 4 communicate with the 3rd, the 4th sealing joint of two position four-way valves 5.
