FIG. 2 is a schematic diagram: the utility model discloses diaphragm compressor's control valve member work flow chart.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a diaphragm compressor for negative pressure air intake includes a box 1, a left cylinder 2, a right cylinder 3 and a control valve 4, the left cylinder 2 and the right cylinder 3 are respectively installed at the left and right sides of the box 1, the left cylinder 2 and the right cylinder 3 have the same structure but different sizes, the left cylinder 2 and the right cylinder 3 both include an upper cylinder 5, a lower cylinder 6 and a diaphragm located at the middle position of the upper cylinder 5 and the lower cylinder 6, the upper cylinder 5 includes an air inlet 8 and an air outlet 9, and the lower cylinder 6 includes an oil inlet and an oil outlet. An oil inlet of the lower cylinder body 6 is connected with the box body 1 through an oil pipeline 7, and the oil pipelines 7 of the left and right cylinder bodies are respectively provided with a control valve 4. The control valve 4 is used for controlling oil inlet amount of the left cylinder body 2 and the right cylinder body 3, the control valve 4 is controlled by using a pressure value, when the pressure value reaches a set value, the control valve 4 is opened, hydraulic oil from the tank body 1 enters the oil inlets of the left cylinder body 2 and the right cylinder body 3 through only a pipeline, when the pressure value is lower than the set value, the control valve 4 is closed, and the hydraulic oil stops entering the tank body.
As shown in fig. 2, the working method:
the left cylinder body and the right cylinder body of the diaphragm hydraulic machine are divided into an upper cylinder body 5 and a lower cylinder body 6, a deformable diaphragm is arranged between the upper cylinder body 5 and the lower cylinder body 6, a cavity formed by the diaphragm and the upper cylinder body 5 is an air cavity, a cavity formed by the diaphragm and the lower cylinder body 6 is an oil cavity, when the diaphragm hydraulic machine works, air enters the cylinder body through an air inlet 8, the air extrudes the diaphragm downwards, a piston in an oil cylinder is in a return stroke state, the air enters the air cavity, after the process is completed, the piston is changed into a process state, the piston enables the diaphragm to move upwards through compressed hydraulic oil, the space where the air is located is compressed in the process, and the air is discharged through an exhaust port of the cylinder body after being changed from a low-pressure state to a high-pressure state.
Therefore, in the whole process of air intake and air exhaust, the pressure change of the air cavity and the oil cavity is greater than the pressure of the oil cavity by the pressure of the air cavity and the pressure change of the oil cavity, the pressure of the oil cavity is greater than the pressure of the air cavity, when the diaphragm compressor is under the normal air intake pressure, the air pressure is generally greater than 1 atmosphere, and therefore the air pressure value can effectively reach the condition that the pressure of the air cavity is greater than the pressure of the oil cavity to compress air.
However, when the diaphragm compressor is used for negative pressure air intake, the pressure in the air cavity needs to be adjusted to realize that the required air cavity pressure is greater than the oil cavity pressure, so that the oil inlet amount of the left cylinder body and the right cylinder body is controlled by the control valve 4 to control the pressure in the oil cavity. The control valve element 4 is set at a set pressure value according to the pressure of the negative pressure intake air.
