Definitions
- the invention relates to a Ventilbaukastensyste 'm, in particular the valves can be constructed such as "pre-controlled pressure-limiting and pressure control valves" are known under the technical terms.
- Pressure limiting valves are regularly those valves by which the inlet pressure is limited by the function element, which is closed when it is at rest, opening the outlet to the tank when the set pressure is reached. This is done by opening against a closing force of a closing element.
- the closing element is acted upon by the medium pressure, which is controlled by a pilot valve. As a result, the pressure difference between the beginning and end of opening is very small.
- This type of pilot-operated pressure relief valve is the most common type of valve protection for hydraulic systems as a whole.
- the pressure regulating valves which are also referred to as pressure reducing valves, are those that keep the lower outlet pressure (secondary pressure) constant when the inlet pressure changes (primary pressure).
- Pressure control valves in this regard can also be pilot-controlled and these are then often used to reduce the pressure in the case of larger fluid flows.
- Manually operated pilot valves, but also electrically operated pilot valves are used for the mentioned pilot control, the latter being controlled by a magnet, usually in the form of a proportional magnet system.
- the magnets in question can be provided with an emergency pressure actuation and thus allow the valve to be adjusted by hand even if they fail.
- switching magnets in particular proportional magnet systems, with inverted characteristic curves are known, ie the opposite effect is achieved as with a known proportional magnet system, that is to say the valve is kept in its closed position when the proportional magnet is not energized ( so-called fail-safe applications).
- the object of the invention is to create a new valve concept with which it is possible to help avoid the disadvantages described, in particular to reduce the costs in the manufacture and maintenance of valves.
- a related problem is solved by a modular valve system with the features of claim 1 in its entirety.
- the modular valve system according to the invention is provided with at least one valve housing which has standardized nominal sizes at its opposite ends both on the inside and outside circumference and on the inside of the housing for attaching further valve components, such as a valve piston, at least one energy store, a pilot part (pilot valve) and at least one Fluid connection or for fixing the valve designed in the manner of a screw-in cartridge to other components (valve block).
- valve in particular in dependence on the application case the "pilot part so that for one type of main valve assemblies themselves can provide a hand-operated pilot control, but also one with proportional magnets with and without emergency pressure actuation as well as with and without an inverted characteristic and switching behavior.
- the other valve components such as the valve piston and the energy accumulator (compression spring) acting on the valve piston, can also be standardized in their size and adapted to the specified valve housing.
- FIG. 1 shows four different structures of a pilot-operated pressure relief valve with a predeterminable nominal size
- Fig.2 four different structures of a pilot-controlled pressure control valve with a predetermined nominal size.
- the pilot valves shown under I correspond to each other both in the embodiment according to FIG. 1 and according to FIG. 2.
- the figures show a manually operated pilot valve 10, an electrically operated pilot valve in the form of a proportional magnet 12, a corresponding proportional magnet 14 with emergency pressure actuation 16 and a proportional magnet 18 with an inverted characteristic curve compared to the embodiments 12, 14.
- the manually operable pilot valve 10 has a valve seat 20 and a valve part 22.
- the valve part 22 is supported against an energy store in the form of a compression spring 26, the closing force of which can be predetermined via an adjusting part 28.
- the adjusting part 28 is in turn guided in an adjusting housing 30 and the closing force can be predetermined manually by means of a hexagon screw 32 with locking ring 34 which can be screwed onto the adjusting part 28.
- Manually adjustable pilot valves 10 are known in the prior art, so that no further details will be given here.
- the pilot valve thus completed can be screwed into one end 38 of the valve housing 40.
- a further energy store in the form of the compression spring 44 is then introduced, at one end of which the main piston 46 is supported, which is supported at its other end on a multi-part end part 50, which in the lower free end 42 of the Valve housing 40 can be screwed in.
- main control stage II and therefore the actual main valve is standardized in the form of a pressure relief valve and, as the further assembly lines 36 demonstrate, appropriately modified pressure springs 26 and adjusting parts 28 are used with unchanged valve parts 22 and pilot chambers 20 in order to achieve changed pressure relief valves with accordingly Modified pilot control stages I with the versions mentioned on different switching magnets 12, 14 and 18.
- valve housing 40 If a different fluid volume flow is to be controlled with the complemented overall valves III according to the valve construction system according to the invention, the nominal sizes on the valve housing 40 must be changed accordingly, in particular with reference to the inner and peripheral sides at the opposite ends 38 and 42 and with respect to the interior of the housing 52nd
- the design for the pilot-controlled pressure control valve is chosen accordingly, in particular the pilot stage I is essentially the same as the pilot stage I in FIG. 1, with the manually operated pilot valve 110 in addition to that Energy storage in the form of the compression spring 26 occurs another energy storage in the form of the compression spring 154, which engages on the opposite side of the pilot chamber 120.
- the relevant structure is also known, so that it will not be dealt with in more detail here and if the components according to the modified embodiment according to FIG. 2 correspond to the structure of a valve concept according to FIG. 1, the same reference numerals are used. which are only increased by 100 each. What has been said so far also applies to the embodiment of a pressure control valve according to FIG. 2.
- control piston 146 has a nozzle body 156 and otherwise the valve housing 140 is adapted to a pressure control valve from its fluid connections in accordance with the task.
- valve housing 140 with its valve components must be adapted, provided that the fluid flows to be controlled change in terms of volume and / or pressure.
- diesel Use the pilot control stages as used in Fig. 1 for the valve concept according to Fig. 2.
- the modular valve system according to the invention allows the valve obtained in each case to be designed in the manner of a screw-in cartridge, so that in this way both the pressure-limiting and the pressure-regulating valves can be defined on further structural components, for example in the form of a valve block in an overall hydraulic system.
