Definitions

  • the present invention relates to a system for fittings comprising a tap, an electro-hydraulic actuator for actuation of the valve and an actuator control device, in especially in environments where a large number of taps are each connected on the one hand to a common source of electric current and on the other hand to a central information processing system, in particular in so-called harsh environments, for example in ships.
  • the control device consists of an electric motor, a block hydraulic comprising a hydraulic pump and a hydraulic tank, and an electronic assembly for local control of the tap.
  • the actuator control devices are there generally made up of two parts, namely a first part comprising a housing, in which the electric motor and the block are located hydraulic, comprising a pump and a reservoir, and a second part with a cabinet or small cabinet in which there is a post local control electronics, including a PLC.
  • the present invention aims to overcome these drawbacks by proposing a new control device for an electro-hydraulic actuator a tap, which offers more functionality for controlling and valve control, including, for example, the possibility of manual control in the event of failure of the central control system, monitoring the motor temperature, its amperage and the time maneuvering, end-of-travel discrimination, level monitoring oil, an indication of movement, etc., without, however, propensity to fail the device when exposed to an environment difficult, especially in a ship, does not increase.
  • the system is less sensitive to harsh environments and especially in marine environments, for example at a humidity level Student.
  • the system is less bulky than the systems of the art anterior, which makes it particularly suitable for use in boats or ships.
  • a valve system is such that defined in claim 1.
  • the housing common has an access opening to part of the assembly electronic, in particular a part for a local order.
  • the housing common has a second access opening to the connectors for the connection of the motor and the electronic assembly to the electrical and data power. So, just as in the case of the access opening to the electronic control part, when connects the two electrical power networks and data from the central control system and the network central power supply, it is not necessary to remove the housing, and thus avoids subjecting the control device to the actuator under difficult conditions, in particular a high humidity level.
  • the common housing has an auxiliary compartment in which are located connection terminals for connectors, auxiliary compartment being sealed against fluids and dust, compared to the rest of the case.
  • the housing has a second auxiliary compartment in which is located said part of local control, notably manual, of electronics.
  • the electronic assembly includes a microcontroller allowing integrate the control and command functions of the motor and pump.
  • Means can also be provided for performing the interpretation. operator commands. One can also provide a system of restitution of end positions, and digital electrical signals or proportional.
  • Means can also be provided for monitor motor temperature, motor amperage or time engine operation. Means can also be provided for end of race discrimination. Means can also be provided for high and low oil level monitoring. We can also provide means for indicating movement. We can also provide means diagnostic and predictive maintenance.
  • the present invention also relates to a system for valves comprising an electro-hydraulic actuator and a device for control according to the invention.
  • the tap can be a tap quarter turn or a linear tap.
  • Figure 1 is an overview of a valve system in a ship having a central data processing system, a central system power supply and a plurality of electro-hydraulic valves and actuators associates each linked to central systems.
  • Figure 4 is an overview of the actuator hydraulic, its control device and its associated tap.
  • Figure 5 is a sectional view of the housing of Figure 2 comprising the following hydraulic actuator control device the invention.
  • FIG. 1 there is shown a valve system In a boat.
  • Several R valves each have their own actuator 1 hydraulic.
  • Each of these valve + actuator assemblies hydraulics are connected on the one hand by electrical cables 2 to a system central power supply 3, and secondly, by buses communication, i.e. data transmission lines, to a 4 central processor governing the central command and control of these taps R.
  • the device 5 for controlling the hydraulic actuator consists of a housing 6 in which is enclosed a motor 7, a hydraulic block 8 and an assembly 9 electronic (in the form of printed circuit boards for example) allowing local command and control of the control device 5 of the hydraulic actuator.
  • the hydraulic block 8 includes a pump 10 to gear, an oil tank 11 and hydraulic circuits 12 comprising hydraulic valves 12 for the connection with the hydraulic actuator 2 in view of its control by hydraulics.
  • the common box 6 is made up a side wall 18 which goes all around a bottom 14 and a top 15 which is fixed to the rest of the case by screws 18 screwed into an upper flange 17 projecting inwardly from the side wall 18.
  • a waterproof and flexible membrane 24 can be provided interposed between the pushbuttons 28 and the outside, so that the operator can press the buttons by pressing the membrane which transmits to the buttons 23 the thrust of the operator, the membrane being arranged in a sealed manner, so that when the operator performs the control by pushing the buttons, it does not expose the inside of the case common to the difficult external environment, in particular to an environment at high humidity.
  • auxiliary compartment 29 in the common box in which part 22 of manual control is received local control device.
  • a opening 30 which is discovered by unscrewing a plug 31 which can be screwed tightly over the opening.
  • This opening gives access to blocks 32 terminals for the connection of the electrical network and the data respectively to the engine and to the electronic assembly 9, which found in the case.
  • These terminal blocks 33 are themselves enclosed in an auxiliary compartment 34, so that when carrying out the connection of the two power and data networks, the rest of the housing is not subject to a difficult environment, especially at a low high humidity.
  • the hydraulic pump is a gear pump. We could obviously provide other types of pumps according to the invention.
  • the set 9 of local control electronics is consisting of printed circuit boards 40 on which circuits are provided electronics allowing the control of the electric actuator in function of a certain amount of data obtained from several different sensors arranged either in the tap, in the actuator, or in the device actuator control.
  • Data signals are either analog signals, or digital signals. In the case of analog signals, you can provide an analog / digital converter upstream of the box which transform the signals into digital signals before sending them to printed circuit boards or cards of the electronic assembly 9.
