Abstract
The utility model discloses an air compressor control system, which comprises an air release valve, an air inlet valve, a pressure switch and a control pipe. The air release valve is fixedly connected with the air inlet valve, and the pressure switch is connected with the air release valve by the aid of the control pipe. The air compressor control system is extremely simple, is stable and reliable in running and greatly saves cost.
Description
Technical field
The utility model relates to a kind of control system, particularly a kind of air compressor control system.
Background technique
Air compressor is used for general power gas source, and it is widely used in industries such as machinery, medical treatment, weaving, food, electric power, automobile, iron and steel, oil, chemical industry, railway, building materials and military project.In general air compressor control system, as shown in Figure 1, the air compressor control system comprises solenoid valve 11, atmospheric valve 12 and suction valve 13, and solenoid valve 11 is fixedlyed connected with atmospheric valve 12, and atmospheric valve 12 is fixedlyed connected with suction valve 13.Be loading and the unloading that electric/dead electricity is controlled machine that get by solenoid valve, the pressure signal of solenoid valve is taken from the gas pressure in the barrel of oil and gas.
The operation of machine with stop to be connected a pressure switch and control by gas holder, pressure switch is a kind of simple pressure control device, when being reached rating value by measuring pressure, pressure switch can give the alarm or control signal.The working principle of pressure switch is: when by the measuring pressure overrate, the free end of elastic element produces displacement, directly or after relatively promotes switching element, changes the on off operating mode of switching element, reaches control by the purpose of measuring pressure.The elastic element that pressure switch adopts has single-coil spring pipe, diaphragm, bellows and bellows etc.Pressure switch is used in the start-stop state of mainly regulating air compressor above the air compressor, allows air compressor shut down rest by the pressure of regulating in the gas holder, and machine is had the maintenance effect.In the debugging of air compressor factory, be adjusted to specified pressure according to client's needs, set a pressure reduction then.For example, compressor starts starts, and inflates to gas holder; time eight kilograms of pressure, air compressor is shut down or unloading, and air compressor begins again to start in the time of pressure to six kilogram; a pressure difference is arranged around here, and this process just can allow compressor have a rest, and reaches the effect of protection air compressor.
Above-mentioned working principle is to control the operation of machine and stop by pressure switch, controls the unlatching and the loading of machine by solenoid valve.Prescribe a time limit compressor emergency shutdown, solenoid valve dead electricity when reaching going up of pressure switch setting; Prescribe a time limit when reaching the following of pressure switch setting, unit operation, solenoid valve gets electric, and unit loads.
The defective that existing air compressor control system exists is: control principle is too complicated, by pressure switch control unit operation, reach the electric/dead electricity that gets of solenoid valve by output signal, unreliable by the operation of electromagnetic valve suction valve system again, the cost height, a solenoid valve will spend hundreds of unit, bring the huge waste of resource and capital to the client.
The model utility content
Technical problem to be solved in the utility model provides a kind of air compressor control system, and it makes control system become very simple, stable and reliable operation, and saved cost greatly.
For solveing the technical problem, the utility model provides a kind of air compressor control system, described air compressor control system comprises atmospheric valve and suction valve, atmospheric valve is fixedlyed connected with suction valve, it is characterized in that, described air compressor control system also comprises pressure switch and control valve, and pressure switch is connected with atmospheric valve by control valve.
Positive progressive effect of the present utility model is: the utility model makes control system become very simple, stable and reliable operation, and saved cost greatly, also eliminate unloading of pressure switch place and put noise.
Description of drawings
Fig. 1 is the structural representation of existing air compressor control system.
Fig. 2 is the structural representation of the utility model air compressor control system.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 2, the utility model air compressor control system comprises pressure switch 1, atmospheric valve 2, suction valve 3 and control valve 4, and pressure switch 1 is connected with atmospheric valve 2 by control valve 4, and atmospheric valve 2 is fixedlyed connected with suction valve 3.
The working principle of the utility model air compressor control system is as follows: when unit reaches pressure switch upper limit setting pressure (for example being eight kilograms), the pressure switch action, unit is out of service, simultaneously, gas in the gas holder is by the pressure switch pipeline of releasing, the control suction valve cuts out suction valve; When threshold pression (for example six kilograms) that unit is set to pressure switch, pressure switch automatically resets under spring action, pressure switch is unloaded to put simultaneously and mouthful closes, and at this moment, unit brings into operation, and often drives the air valve suction valve into and also begins to load, the set steady operation.
The utility model is by improving pressure switch construction, is that the venting body that unloads at pressure switch place is recycled, and controls opening/closing of air inlet valve position, by this road gas pressure, control to unload and put valve simultaneously, unload the pressure of putting in the barrel of oil and gas, simplify the suction valve structure, reduced cost.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, protection domain of the present utility model is limited by appended claims.
