In one embodiment of the utility model, a gas-liquid linkage actuating mechanism comprises a control system, a main valve 1, a valve-opening gas-liquid tank 2, a valve-opening connecting pipeline 3, a valve-closing gas-liquid tank 4, a valve-closing connecting pipeline 5 and a first gas transmission pipeline 6, wherein the main valve 1 is respectively communicated with the valve-opening gas-liquid tank 2 and the valve-closing gas-liquid tank 4, and further comprises a second gas transmission pipeline 7, a gas storage tank 8, an isolation tank 9, a pressure monitoring device and a solenoid valve 10; be provided with gas holder 8 and insulation jar 9 on the second gas transmission pipeline 7, insulation jar 9 sets up in the bottom of gas holder 8 and communicates with gas holder 8 through the connecting pipe, and pressure monitoring device is used for monitoring and adjusting the internal pressure of gas holder 8 and insulation jar 9, and pressure monitoring device and solenoid valve 10 communication connection, solenoid valve 10 set up in the entrance of first gas transmission pipeline 6.
Specifically, as shown in fig. 1 to 2, in the gas-liquid linkage actuating mechanism of the present utility model, since the second gas transmission pipeline 7 is communicated with the gas storage tank 8, when the high-pressure gas enters the first gas transmission pipeline and the second gas transmission pipeline, after the high-pressure gas enters the first gas transmission pipeline and the second gas transmission pipeline, the gas storage tank 8 can temporarily store part of the high-pressure gas, so that stable gas pressure and flow can be provided when the present utility model operates, and meanwhile, impact on the gas-liquid linkage actuating mechanism can be reduced, the service life of the gas-liquid linkage actuating mechanism can be prolonged, and energy sources can be saved. In addition, because the air storage tank 8 can generate certain impurities such as rust, iron slag or water in the air storage tank 8 after long-term use, the isolation tank 9 is arranged at the bottom of the air storage tank 8, and the impurities in the air storage tank 8 can be collected and isolated through the isolation tank 9, so that the impurities in the air storage tank 8 can be prevented from being conveyed to other parts and blocking in the use process, and the air storage tank is reliable in use.
According to the existing gas-liquid linkage actuator and the actual operation condition thereof, the gas-liquid linkage valve of the main valve chamber is normally closed for one stroke, and the pressure of the gas storage tank 8 is required to be above 3.5 MPa. The branch valve chamber gas-liquid linkage valve is normally closed for one stroke, and the pressure of the gas storage tank 8 is required to be more than 1.8 MPa. Further, if the pressure of the air storage tank 8 is lower than the rated pressure of the valve which can be normally closed, the air storage tank 8 is in a low pressure state, in the utility model, the pressure in the air storage tank 8 and the isolation tank 9 can be monitored by arranging the pressure monitoring device, and a worker can set the action pressure value, the delay time, the action time and the like of the pressure monitoring device, and the data of the pressure of the air storage tank 8 and the like can be transmitted to the control system by the pressure monitoring device, so that an alarm signal is sent to the control system when the power gas leaks or the pressure of the air storage tank 8 is lower than the rated pressure and other abnormal conditions, thereby being convenient for the worker to judge whether the power gas leaks or not, the joint of the first gas pipeline and the second output pipeline is in a sealing failure or not, and the like, so that the worker can go to the site in time to maintain, check the potential safety hazard, ensure the normal operation of the gas-liquid linkage actuating mechanism, and effectively avoid the safety accidents caused by the power gas leakage.

In addition, the difference value between the pressure of the air storage tank 8 fed back by the pressure monitoring device and the pressure of the trunk line and the pressure of the branch line can be set manually, and a worker can adjust the pressure of the air storage tank 8 by the pressure monitoring device up or down.
It should be noted that, since the pressure monitoring device is electrically connected with the electromagnetic valve 10, and the staff can set the action pressure value, delay time, action time and the like of the pressure monitoring device, after the staff starts the automatic mode control through the control system, the control system carries out signal transmission on the pressure monitoring device, at this time, the pressure monitoring device judges whether to open the electromagnetic valve 10 for air supplement, that is, the pressure monitoring device judges whether the air supplement time is in the air supplement time set by the staff, if the air supplement time is in the set air supplement time, the electromagnetic valve 10 is opened and can supplement air to the air storage tank 8, otherwise, the air storage tank 8 is closed; when the air supply time reaches the time set by the pressure monitoring device, the pressure monitoring device controls the electromagnetic valve 10 to close, thereby stopping air supply to the air storage tank 8.
It should be noted that, for the conveying manner how the high-pressure gas entering the first gas conveying pipeline is conveyed to the second gas conveying pipeline, the connection structure of the first gas conveying pipeline and the second gas conveying pipeline is the mature prior art, such as the conveying manner of the natural gas entering the gas conveying pipeline in the patent document with publication number CN111322451B, which is not described in detail in the present application, and the specific structure of the present application has been omitted in the drawings of the specification, the present application is only aimed at solving the problem that the existing gas-liquid linkage executing mechanism is not convenient for carrying out gas supplementing and pressure monitoring on the gas storage tank 8, and the normal working of the gas-liquid linkage executing mechanism is affected.
