  • a compressed air production plant mainly consisting of an oil-bath screw compressor, a air / oil separator tank, an accumulation tank of pressurized air, further comprising radiators separate for cooling air and oil, thermostatic valves, non-return valves, maximum pressure, (pressure switches or safety devices), of the minimum pressure and other control and control, arranged on the installation conduits.
  • a valve which has the function intercept the passage of air from the outside to inside the circuit.
  • regulator suction of which a particular form of construction is described in Italian patent applications no. 85.521 / A / 90, VI983A00069 and VI93A000101, deposited in the name of the Applicant, is mounted on the suction mouth of the screw compressor and has the function of adjusting or interrupt the flow of air from outside by according to the operating needs of the installation.
  • the suction regulator is essentially made up by an alternating rectilinear cursor which is caused by the balancing effect between the action of thrust generated by the pressurized air taken from the circuit, and by the pushing action, in the opposite direction of the previous, generated by the outside air and by the action of resistance of one or more opposing springs.
  • the displacement of the metal disc, constituting the cursor, relative to the fixed seat can be of two types, namely proportional movement or full movement (switching).
  • the operation of the suction regulator in the two different modes is possible that by making enough hydraulic circuits complex and including valves that control the pressure fluid, valves that regulate fluid flow, and valves which control the flow of the fluid, i.e. valves that define the priority directions in the pipeline network.
  • the object of the present invention is to provide a system that achieves the same result as known circuits, but with notable simplifications mechanical and construction. This goal is achieved by through the features of the game Characterizing of claim 1.
  • the monoblock according to the invention it is possible to generate a back pressure capable of balancing the action of negative thrust which generates on the mechanics of the pump screw, during proportional operation and during vacuum operation.
  • one provides, thanks to the particular internal conformation of the monobloc, and by equipping the two external solenoid valves of an electronic card order, the possibility of achieve a gradual and not instantaneous stop of the compressor, so as not to damage the mechanics of the screw pump.
  • the suction regulator is fitted on the outside air intake mouth and over the mouth of connection to compressor, movable fasteners, preferably flange.
  • Another characteristic of the invention resides in the possibility of making a suction regulator of the type called "modular" where the same body of said regulator suction is likely to be fitted with another combination of flange fittings and distributors monoblocks. This allows to realize, quickly and with remarkable economy, devices meeting requirements specific to each user.
  • the installation of compressed air production regulated by the distributor monobloc 001 according to the invention, essentially consists a suction regulator 002 that intercepts air outside and feeds it to the oil-filled screw compressor 003, powered by an electric motor.
  • the mixture of fluid under oil / air pressure produced by the compressor enters a separation tank 004, where separation of air and oil occurs.
  • the pressurized air will then fill the tank 005, waiting to be used, while the oil, after passing through the radiator 006, returns to the compressor 003 in closed circuit.
  • the 001 one-piece distributor according to the invention supplied by pressurized air taken from the separator tank 004, via conduit 007, and controlled by the action of the two solenoid valves 008 and 009, is mounted on the body of the suction regulator 002 to adjust the proportional or commutative operation, this to regulate and / or interrupt the air flow from outside depending on the needs of the installation, according to the methods and diagrams which are described in the following.
  • the one-piece distributor 001 consists of a body 1, provided with a plurality of cavities in which the devices capable of carrying out the action of distributing compressed air control and a network of conduits which put said cavities in communication.
  • the body 1 in the body 1 are housed two valves with fixed throttle with guided discharge 2A and 2B, a valve quick discharge 3, an air injection control valve 4 in the compressor screw, a control valve proportional 5, two selector valves 6A and 6B and one calibrated nozzle 7.
  • Main conduit 111 supplies the relief valve quick 3 and valve 4 and, on this conduit, connect the conduits 112A and 112B which supply the respective valves 2A and 2B, and the conduits 113 and 114 which supply, at their tower, the corresponding solenoid valves 008 and 009, on which connect the conduits 115 and 116 which communicate with the corresponding valves 2A and 2B.
  • the conduit 116 is also connected by the branch 117 to the quick relief valve 3 from which the conduit 118 connected to valve 6A and conduit 119, provided with setting 9, through the discharge opening 101.
  • the valve 2B is put in communication with the valve selector 6B via the conduit 120, which via the bypass 121, is in communication with the pressure adjusting screw minimum 8, through the discharge port 102 and the conduit discharge 119.
  • the function of the monobloc distributor 001 is to closing of the 021 external air intake opening by moving cursor 022 of the suction regulator 002, to allow the air contained to be pressurized in the circuit.
  • valve 2B it is possible feed the conduit 120 and, through the selector valve 6B, the conduit 126 and thus cause the displacement of the slider 022 and the complete closing of the suction mouth 021.
  • a screw is mounted minimum pressure setting 8 which, set by the operator, ensures a minimum air pressure value in the circuit and allows possible pressure evacuation by through conduit 119, intercepted by the screw discharge setting 9, which communicates with the outside.
  • Switching full load regulation (see fig. 4), which involves the total displacement of the cursor 022 for opening the suction mouth 021, is done in exciting the two solenoid valves 008 and 009 which, by through discharge pipes 115 and 116 respectively, modify the state of the two valves routing 2A and 2B.
  • a small suction valve 023 ensures the maintenance a minimum intake of air from the outside.
  • the quick release valve 3 opens, so that the air, passing through ducts 118 and 127, which communicate via the directional valve 6A, will supply valve 4 which, consequently, allows the air from the main inlet duct 111, passing through the conduit 128 and the check valve 10, to return to the compressor 003 by achieving a back pressure in this way positive in the mechanics of the screw pump, reducing wear, vibration and resulting noise.
  • valve 3 further allows, by via conduits 007, 111 and 119, to discharge the air contained in the air / oil separator 004 to the external environment, with the interposition of a filter, not shown, and which, in addition to the filtration action of so that said air can return to the circuit, limit the noises.
  • Proportional full load regulation (see fig. 6), with cursor 022 which opens according to the amount of air demanded by consumption is achieved by exciting the 009 solenoid valve, while the 008 solenoid valve remains closed so that air, passing through the duct 122, enters the proportional control valve 5 from where, passing through conduits 125 and 126 and under the effect of the action of the selector valve 6B, it will activate said slider which proportionally adjusts the opening of the suction mouth 021.
  • Bypass 124 will feed, through the valve selector 6A and the conduit 127, the valve 4 which maintains the positive action of back pressure in the mechanics of the screw pump, even during this phase.
  • the branch 123 is provided with the calibrated nozzle 7 which serves to balance the interaction between the valve proportional 5 and the movement of the cursor 022.
  • the progressive shutdown action of the compressor (see fig. 7) is done with the use of an electronic card which, simultaneously and progressively de-energizes (firm) the solenoid valve 009 and excites (opens) the solenoid valve 008.
