Technical Field

The utility model relates to an admission valve technical field, especially a compact structure's admission valve of integrated admission valve compact structure, reduce whole valve height, reduce whole valve volume, reduction in production cost, simple to operate.

Background

The air inlet valve consists of a valve body, a rotary check valve, a butterfly valve and a control cylinder. The rotary check valve is provided with a balance weight and a fluororubber sealing ring, when the compressor is started, a main machine of the compressor sucks air, and the check valve is rapidly opened due to pressure difference; when the engine is stopped, the check valve can be closed quickly and tightly in time under the control of the counterweight after the pressure difference is lost, so that the phenomenon of oil discharge during the stop is avoided. The opening and closing of the butterfly valve are controlled by the control cylinder, and the butterfly valve is opened or closed according to the extension length of a piston rod of the control cylinder, so that the air input of the compressor is adjusted.

The rotary check valve with the counterweight can be quickly closed after emergency shutdown, so that oil gas in a host is prevented from being sprayed out; 2, the specially designed control cylinder can set the butterfly valve opening pressure according to the requirement; 3, the control cylinder with the independent design patent is simple and durable, and the diaphragm of the diaphragm type cylinder is prevented from being frequently damaged. The design service life is 300 ten thousand times.

The pressure rises, part of the pressure is released to the upper part of the air inlet valve through the emptying valve, and the residual pressure is maintained. 2, loading, star-delta conversion of a motor, opening an electromagnetic valve, enabling the pressure in the oil gas tank to reach a pressure reducing valve through a line, pushing a control cylinder to open a butterfly valve, and fully opening an air inlet valve to suck air; the emptying valve is closed at the same time through the pressure of the electromagnetic valve, the machine is not emptied any more, and the pressure in the tank continuously rises to supply air to the outside. And 3, unloading, namely when the pressure rises to the upper limit value of the differential pressure gauge, the differential pressure gauge sends an electric signal to the electromagnetic valve, the electromagnetic valve is closed, the butterfly valve is closed when the control cylinder is not pressed, the small hole is maintained for air inlet, and the emptying valve is opened to release the pressure in the oil tank to the basic oil pressure. And 4, stopping the machine, stopping the motor, stopping the main engine, stopping the check valve at the lower part of the air inlet valve, isolating the inside and the outside of the machine, and continuously emptying the emptying valve to the external atmospheric pressure.

The existing air inlet valve has a single air pressure adjusting mode, and needs an air inlet valve which is integrated with an integrated air inlet valve and has the advantages of compact structure, reduction in the height of the whole valve, reduction in the volume of the whole valve, reduction in the production cost and convenience in installation.
