Definitions

the present invention relates to a valve system comprising a valve, an electro-hydraulic actuator for actuating the valve and an actuator control device, particularly in environments where a large number of valves are each connected to the valve. on the one hand to a common source of electric power and on the other hand to a central information processing system, in particular in so-called difficult environments, for example in ships.
the control device consists of an electric motor, a hydraulic block comprising a hydraulic pump and a hydraulic reservoir, and an electronic assembly for local control of the valve.
valves of this kind are generally constituted in two parts, namely a first part comprising a housing, in which is located the electric motor and the hydraulic block, comprising a pump and a reservoir, and a second part comprising a cabinet or small cabinet in which there is a local electronic control station, including a PLC.
the present invention aims to overcome these disadvantages by proposing a new control device of an electro-hydraulic actuator of a valve, which offers more functionalities for controlling and controlling the valve, including, for example, the possibility of manual control in the event of failure of the central control system, monitoring of the engine temperature, its amperage and operating time, end-of-travel discrimination, level monitoring oil, an indication of movement, etc., without the propensity to break down the device when exposed to a difficult environment, especially in a ship, does not increase.
the system is less sensitive to harsh environments and in particular to marine environments, for example at a high humidity level.
the system is less bulky than prior art systems, which makes it particularly suitable for use in ships or ships.
a valve system according to the preamble of claim 1 is known from EP-A-0665381.
a valve system is as defined in claim 1.
a local control that is to say independent of the central power supply and control and control systems and assigned respectively to the actuator, is thus possible.
an operator or a user can manually control the valve in the immediate vicinity of it being assigned to it.
the common housing comprises an access opening to a part of the electronic assembly, in particular a part for a local control.
the common housing comprises a second access opening to the connectors for connecting the motor and the electronic assembly to the power and data networks.
the common housing comprises an auxiliary compartment in which are the connection terminals for the connectors, the auxiliary compartment being sealed against the fluids and dust, relative to the rest of the housing .
the housing comprises a second auxiliary compartment in which is located said local control part, in particular manual, of the electronics.
the electronic assembly comprises a microcontroller for integrating the control and control functions of the motor and the pump. It is also possible to provide means for performing the interpretation of the operator's commands. It is also possible to provide a system for restoring end-of-travel positions and digital or proportional electrical signals. It is also possible to provide means for monitoring the engine temperature, the engine amperage or the engine operating time. It is also possible to provide end-of-stroke discrimination means. It is also possible to provide means of monitoring the oil level up and down. It is also possible to provide movement indicating means. Predictive diagnosis and maintenance can also be provided.
the present invention also relates to a valve system comprising an electro-hydraulic actuator and a control device according to the invention.
the valve may be a quarter turn valve or a linear valve.
FIG. 1 is an overview of a valve system in a ship comprising a central data processing system, a central power supply system and a plurality of valves and associated electro-hydraulic actuators each connected to the central systems.
FIG. 4 is an overview of the hydraulic actuator, its control device and its associated valve.
Figure 5 is a sectional view of the housing of Figure 2 comprising the control device of the hydraulic actuator according to the invention.
valve system in a boat.
valves R each have their own hydraulic actuator 1.
Each of these valve + hydraulic actuator assemblies are connected on the one hand by electrical cables 2 to a central electrical power supply system 3, and on the other hand by communication buses, that is to say data lines, to a central processor 4 controlling the central control and control of these valves R.
the 5 control device of the hydraulic actuator consists of a housing 6 in which is enclosed a motor 7, a hydraulic block 8 and an electronic assembly 9 (in the form of printed circuit boards for example) for control and control local control device 5 of the hydraulic actuator.
the hydraulic block 8 comprises a gear pump 10, an oil tank 11 and hydraulic circuits 12 comprising hydraulic valves 12 for connection with the hydraulic actuator 2 for hydraulic control thereof.
the housing 6 common consists of a side wall 18 all around a bottom 14 and a top 15 which is fixed to the rest of the housing by screws 18 screwed into a rim 17 upper projecting inwards of the side wall 18.
auxiliary compartment 29 in the common housing in which is received the portion 22 of local manual control of the control device.
an opening 30 which is discovered by unscrewing a cap 31 which can be screwed tightly on the opening.
This opening gives access to terminal blocks 32 for the connection of the electrical network and the data network respectively to the motor and to the electronic assembly 9 which are in the housing.
These terminal blocks 33 are themselves enclosed in an auxiliary compartment 34, so that when the two power and data networks are connected, the rest of the housing is not subjected to a harsh environment, especially at a high humidity.
the hydraulic pump is a gear pump.
the local electronic control assembly 9 is constituted by printed circuit boards 40 on which electronic circuits are provided which make it possible to control the electric actuator as a function of a certain number of data obtained from several different sensors arranged either in the tap. either in the actuator or in the control device of the actuator.
the data signals are either analog signals or digital signals.
an analog-to-digital converter can be provided upstream of the box which transforms the signals into digital signals before sending them to the boards or printed circuit boards of the electronic assembly.
