Problems solved by technology

Since only the minimum size of the connecting surface, the position of the threaded hole, the position of the fastening pin and the inlet and outlet holes of the air channel are defined in the above-mentioned standard, it is however possible to provide a mounting hole for the magnetic valve in the area of ​​the second connection. Free space presents the problem that when trying to mount the solenoid valve on the second interface with insufficient free space, in some drives it can cause a conflict between the solenoid valve and e.g. the head of the drive

Embodiment Construction

[0020] As is known, a solenoid valve with a first connection (not shown in the figures) is mounted on the second connection 1 of the regulator. in accordance with figure 1 In the exemplary embodiment of the present invention, this second connection 1 is arranged on the rear side of a separate connection block 2 , and a further connection for a position controller (not shown in the drawing) is located on the front side 3 facing away from this rear side. Embodiments of the second connection 1 are common to those skilled in the field of process instrumentation, which deals with control valves and position regulators, and need not be described in detail here. exist figure 1 The fixing pin 4, the two threaded holes 5 and 6 and the four air channels 7, 8, 9 and 10 of the connection 1 can be seen in the figure.

[0021] The solenoid valve mounted on the second port 1 can be used, for example, for venting the drive, so that the regulator provided thereby moves into a safe position i...

Abstract

The invention relates to an adapter for an assembly having a valve and a positioner, which are designed for pipeless valve mounting according to the guideline VDI / VDE 3847. The adapter (11) is intended to be installed between the valve and the positioner. The adapter enables a variably adjustable position of the valve relative to the positioner, such that possible collisions between the valve and other parts located near the interface (1) intended for the installation of the valve can be largely avoided.

Description

technical field [0001] The invention relates to an adapter for an assembly having a valve and a regulator according to the preamble of claim 1 , wherein the valve has a first connection and the regulator has a corresponding second connection, the first connection and The second connection is designed according to VDI / VDE 3847 for hose-free and pipe-free connection of the valve to the regulator. Background technique [0002] Pneumatic actuating drives (regulators) are usually used to control process valves, in which a pressure is applied to a diaphragm acting on the control device, for example on the closing body of the regulating valve, by means of a gaseous medium, thereby deflecting the diaphragm , the general term "air" is used in this application document for the gaseous medium. The application of variable pressure to the membrane can be achieved on one side, where the membrane is spring loaded on the other side, or can be achieved on both sides, where different Pressu...
