Description

The present invention relates to an actuating valve connection plate

  progressive modular construction, in

  particularly for pneumatic fluids.

  In the arrangement of connection plates, the valves are individually mounted on a base plate.

  The valves themselves only have bore holes

  The connections for the working ducts and

  air supply can be found in the base plate.

  Thanks to this arrangement, we obtain a compact construction

  pact, which allows the exchange of individual valves

  plets without disassembly of neighboring valves To allow exchangeability of valves of different constructions, the configurations of the connection bores are internationally standardized, that is to say that the arrangement of the exit bores of a valve, which must correspond to the holes in the connection plate, is standardized by standardization. This is the case for distributors in DIN 24340, sheet A and ISO 4401 (for

  pneumatic field DIN ISO 5599) and for valves of

  , pressure and regulators in DIN 24340 D or E and ISO 2624 (for DIN pneumatic applications)

24345).

  In the connection plates, individual connection plates, interconnected plates and battery plates are differentiated. The individual connection plates are intended for receiving a valve and have all the necessary connections of the fluid guide channels to the valve. back or sideways

  interconnected plates represent individual plates

  which are constructed so that they can be screwed together into interconnected systems. They are used, under different embodiments, in the hydraulic and pneumatic fields. The battery plates, called collective connection plates, consist of a part for receiving a plurality of valves, which can be mounted in a very narrow space Such collective connection plates are essentially not

  only in the pneumatic field.

  It is known to arrange several connecting plates, called ISO base plates, side by side.

  in modular construction, and to connect them in a

  In addition, for example fluid guide channels, ie working ducts, pressure lines and venting ducts, are machined from one connection plate to the other. working duct exits from each connecting plate for the corresponding valve All fluid guiding channels are guided, each time, in the area of a valve by a single oval connecting channel to the outlet in the plate separation plane By using this predefined connection plate with fixed connection channels, only identical connections can be made with the individual mounted valves. A modification of this predetermined association of the connection channels of the connection plate with the bores. the valve is no longer possible after completion of the connection plate. Thus, for example, a subsequent mounting of a 2/2 dispenser in place of a dispenser ur 3/3, or

conversely, is in principle excluded.

  The object of the present invention is to provide a

  Valve connection, which can be set or adapted to several different functions and is not rigidly limited to a single function.

  For this purpose, the progressive action valve plate of modular construction, in particular for pneumatic fluids, the plates forming a subgroup being arranged individually or multiple next to each other, in which fluid guide channels for the working ducts, pressure lines, vent lines, and adjacent connection plates are arranged in the connection plate. adjacent to each other and connectable, and separate connecting channels each extending fluid guide channels 10 to corresponding valve bores, is remarkable, according to the invention, in that, each time, in the valve housing and opening into a connecting plane, there are provided one or more oval or longitudinal slot shaped recesses, intersecting the fluid guide channels, 15 recesses which can be connected with the corresponding valve bores, to the fluid guide channels machined parallel through each connecting plate via the separate connecting channels, in that the connecting channels in the connection plate can be closed at the same time. means of plugs and sealing rings, opposite to selected valve bores, and in that

  that any switching paths corresponding to the fluid switching, or the number of channels and the number of switching positions of the progressive acting valve, can be determined via the plug and plug-free connection channels.

  The advantages of the invention consist in particular in

  that the connection plate can be connected, in a variable manner, to the valve outlets. Thus, for example, different distributors can be formed on an existing connection plate. Thus, the connection plate module

  In addition, it saves mounting time, in the case where, in principle, new functions must be introduced into a circuit.

  According to another characteristic of the invention, a food

  Appropriate sealing fluid is obtained in that larger diameter recesses for the sealing ring plugs are provided coaxially with the connecting channels or said recesses, opening into the connection plane. To improve the flow, that is, to increase the

  cross-section of passage and, thus, increase the flow, it is further proposed that the stop-ring ethe-10 is in each case, oval or circular.

  Advantageously, an adaptation of the connection channels of the connection plate to the slot-shaped recess of the valve housing is further obtained in that the width of the recesses in the valve housing is smaller than the

  width of sealing ring plugs.

  According to another characteristic of the invention, a separa-

In this case, it is appropriate for the sealing element to be constituted by a metal plate which, on the periphery, is surrounded by an annular seal, and the annular seal is clamped between two connecting plates. . According to a variant, it is provided that the sealing element is constituted by an annular sleeve which surrounds the outer peripheral zone of a metal plate, and that the metal plate with the annular sleeve is tight.

  between two adjacent connection plates.

  An improvement of the invention consists in that

  The annular seal is arranged sealingly between two adjacent connecting plates.

  The connection of individual connecting plates is relatively difficult because of the fluid guide channels. An advantageous arrangement is that adjacent connecting plates are connected to each other by means of contoured cut-outs and protrusions. gaging into each other, and by means of screws

  extending inclined up and down.
