Integrated valve

The invention relates to an integrated valve. The integrated valve comprises a valve body, a check valve and an exhaust valve. The valve body is provided with an air inlet hole, an air outlet hole, a first exhaust hole and a first valve cavity. The air inlet, the first valve cavity and the air outlet are sequentially communicated, and the first exhaust hole is communicated with the air inlet. The check valve is arranged in the first valve cavity so that air can flow in the direction from the air inlet hole to the air outlet hole. The exhaust valve has an open state and a closed state, and in the open state, gas flows in the direction from the gas inlet hole to the first exhaust hole. In the closed state, gas flows in the direction from the gas inlet hole to the gas outlet hole. Before the compressor is started each time, the exhaust valve can be opened firstly, gas between the compressor and the check valve is exhausted, no-load starting is achieved, the instantaneous starting current of the compressor is red
