Through adopting above-mentioned technical scheme, the setting of relief pressure pipeline shunts steam conduit, and the high-pressure steam transmission in the steam conduit enters relief pressure pipeline, is used for reducing the internal pressure of pipeline through the setting of relief pressure valve, guarantees to be located the normal work of its rear solenoid valve. The pressure transmitter converts the pressure in the pressure reducing pipeline into an electric signal and transmits the electric signal to the controller, and the controller is used for controlling the opening and closing of the electromagnetic valve according to a detection signal transmitted by the pressure transmitter. When the pressure in the pressure reducing pipeline is larger than the adaptive range of the automatic regulating valve, the controller controls the electromagnetic valve to be opened, so that the pressure reducing pipeline is conducted, the pressure in front of the automatic regulating valve is reduced, the automatic regulating valve is prevented from losing efficacy, and the normal operation of an air supply system of the air conditioner is ensured.

Further setting the following steps: the rear of the electromagnetic valve on the pressure reducing pipeline is connected with a pressure reducing valve, the position of the pressure reducing pipeline between the pressure reducing valve and the steam pipeline is connected with a first control valve, and the position of the pressure reducing pipeline between the pressure reducing valve and the steam pipeline is connected with a second control valve.

Through adopting above-mentioned technical scheme, when the too big urgent pressure release of needs of pressure in the steam conduit, open first control valve and solenoid valve when closing second control valve and automatically regulated valve, make the pressure accessible relief valve discharge in the steam conduit for prevent unexpected emergence.

Further setting the following steps: and a pressure gauge is connected to the position of the pressure reducing pipeline in front of the pressure reducing valve.

Through adopting above-mentioned technical scheme, the setting up of manometer makes the staff can know the pressure in the relief pressure pipeline, carries out real time monitoring to the pressure in the pipeline, prevents that the accident from taking place.

Further setting the following steps: the emergency pipeline is connected with an emergency pipeline, two ends of the emergency pipeline are connected to two sides of the steam pipeline located on the automatic regulating valve respectively, a support is fixedly arranged in the emergency pipeline, a spoiler sliding along the axial direction of the emergency pipeline in a reciprocating mode is arranged on the support, a sealing ring matched with the spoiler and used for sealing the emergency pipeline is arranged in front of the spoiler in the emergency pipeline, and a pre-tightening spring used for driving the spoiler to seal the sealing ring is arranged between the spoiler and the support.

By adopting the technical scheme, when the electromagnetic valve and the automatic regulating valve are in failure and are in a closed state at the same time, the pressure in the steam pipeline is prevented from continuously rising to exceed a controllable range; the event sets up urgent pipeline, and pressure gets into urgent pipeline and exerts the effect that the sealing ring removed dorsad in the spoiler of sealing ring, and the spoiler that the sealing ring removed dorsad compresses the pretension spring, and when the pressure in the urgent pipeline was greater than the pretightning force of pretension spring, the spoiler broke away from with the sealing ring and makes urgent pipeline switch on, and the pressure in the steam conduit can realize urgent discharge through urgent pipeline like this, prevents unexpected emergence.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses a with pressure regulation to automatic regulating valve's accommodation to ensure air conditioner air supply system's normal operating.
