Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of valve core composed described in the utility model embodiment, at least comprise two reduction valve, two Pneumatic valves, solenoid valve, one-way valve, positioning work piece, two speed increasers, gas holder, valve actuator FC and control units, wherein;
The suction port of the first reduction valve PRF1 is connected with on-the-spot compressed air outlet port; The air outlet of the first reduction valve connects respectively suction port and the positioning work piece EP of one-way valve CH, solenoid valve SOV on gas holder VT; The suction port of described solenoid valve connects the SC sigmal control mouth of the first Pneumatic valve AOV1 and the second Pneumatic valve AOV2; Described positioning work piece is connected with the second speed increaser BS1 control end with the first speed increaser BS1 respectively;
The suction port of described the first reduction valve is connected with on-the-spot compressed air inlet port, and the air outlet of the first reduction valve is connected with the suction port of the second speed increaser with the first speed increaser respectively; The air outlet of described the first speed increaser is connected with the first gas port C of described the first Pneumatic valve, and the second gas port D of described the first Pneumatic valve is connected with valve actuator; The air outlet of described the first speed increaser is connected with the first gas port A of the second Pneumatic valve, and the second gas port B of described the first Pneumatic valve is connected with valve actuator;
Described the first Pneumatic valve and described the second Pneumatic valve are equipped with the 3rd gas port, and the 3rd gas port of described the second Pneumatic valve is connected with gas holder; Described solenoid valve, positioning work piece, Pneumatic valve are all connected with described control unit.
Working principle of the present utility model is:
Pressurized air in on-the-spot compressed air hose is divided into three tunnels after the first reduction valve, and the first via is connected on solenoid valve; The second tunnel is connected on the one-way valve of gas holder; Third Road is connected on positioning work piece.The pressurized air that enters solenoid valve obtains the SC sigmal control mouth that arrives the first Pneumatic valve and the second Pneumatic valve under electric condition at solenoid valve, promote the spool action of each Pneumatic valve, realize the conducting of the first gas port and second gas port of the first Pneumatic valve, the 3rd gas port of the second Pneumatic valve and the conducting of the 4th gas port.The pressurized air that enters positioning work piece regulates and controlled afterwards the first speed increaser and the second speed increaser through positioning work piece.
Pressurized air in on-the-spot compressed air hose is through the second reduction valve, the second reduction valve outlet minute two-way divides and is clipped to the first speed increaser and the second speed increaser, the air outlet of the air outlet of the first speed increaser and the second speed increaser arrives actuator through the first Pneumatic valve, the second Pneumatic valve respectively, pushing executing mechanism action.
When on-the-spot pressurized air fault, the gas control signal of two Pneumatic valves loses gas, and Pneumatic valve resets and makes the second gas port D and the 3rd gas port F conducting of the first Pneumatic valve under spring action separately; Make the second gas port B and the 3rd gas port E conducting of the second Pneumatic valve.The 3rd gas port of the second Pneumatic valve is connected with gas holder, and pressurized air in gas holder is entered by the 3rd gas port of the second Pneumatic valve, finally enters into actuator, realizes abort situation requirement, simultaneously at the 3rd gas port of the first Pneumatic valve to pressure release in atmosphere.
By above-mentioned valve core composed for control system, this control system comprises integral valve, upstream pressure transmitter, downstream pressure transmitter, with PID adjusting and low pressure, cuts off pressure controller or the PLC of warning function.
When system is used, before valve, the pressure signal of downstream pressure transmitter all regulates access with PID and low pressure is cut off in the pressure controller or PLC of warning function.
Because the pressure of gas main fluctuates larger sometimes, in order to guarantee the operation of the continuous long-term stability of production, when downstream pressure is higher, pressure controller is according to the deviation of downstream pressure setting value and measured value, after PID processes, export a suitable current signal, then by positioning work piece, convert pressure signal to and be sent to speed increaser, then with its output signal, go the action of control cylinder.After integral valve action, the displacement of valve rod feeds back to valve positioner by mechanical device again, in positioning work piece, by comparison control signal and feedback signal, go the aperture of control valve, valve position situation sends Upper system to by electrical signal, realize thus the automatic adjusting of gas pressure, guarantee the stable of pipeline pressure.
When the low warning of gas pipe line upstream pressure, integral valve is according to the low-voltage signal collecting, export a shutoff signal and produce and report to the police, the instantaneous dead electricity of coil of solenoid valve, trigger Pneumatic reversal valve valve rapid-closing, enter self-locking state, cut off the supply of combustion gas, prevent in time the generation of serious accident.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
