Description

The invention relates to a compact distributor with valve inserts with stuffing box packing
for steam and non-toxic media according to the generic term of
Claim 1.

Such compact distributors are used to connect a central line with several branch lines and are equipped with valve inserts with stuffing box packing, with which the branch lines can be individually shut off from the central line. The valve spindle is surrounded by a stuffing box packing and seals the passage for the valve spindle from the inlets and outlets of the valve, so that the required leak protection is guaranteed for piping systems for steam and non-toxic media.

Known distributors of this type consist of a large number of individual parts that must be connected to one another during assembly in a leak-free manner. The pipe string formed by the pipe bridges and T-pieces is sealed at one end by a pipe screw connection or a flange. Between the free nozzles

'if

A separate valve with a stuffing box of a known design is then inserted into each of the T-pieces and the branch lines.

The installation of these well-known distributors is very labor-intensive, especially since the numerous connections between the individual fittings must be carefully sealed and checked for leakage. In addition, the conventional distributor is extremely bulky, so that the planning and installation of the systems in which such distributors are to be used is made more difficult by the large amount of space required.

The object of the invention is therefore to create a distributor of the type mentioned above, which is characterized by a compact design and simple assembly.

This object is achieved according to the invention with the features specified in the claims.
Features solved.

According to the invention, the compact distributor is formed by a one-piece, tubular housing that can be connected to the central line and to which the valve housings for all outgoing secondary lines are welded. These valve housings are designed as T-pieces. The number of individual valves connected to one another without the use of additional sealing elements is thereby considerably reduced. All outlets for the secondary lines branch off at right angles from the tubular housing. The valve inserts with stuffing box packing and two-part coupled spindle are inserted vertically into these T-pieces.

The use of the two-part coupled spindle results in smooth operation, which leads to very small closing moments and thus enables the use of space-saving actuating elements. This makes it possible to arrange the valve inserts with stuffing box packing in a compact manner directly on the tubular housing and the valves can be conveniently operated by hand.

The compact distributor according to the invention significantly simplifies assembly, considerably reduces the space required and, thanks to the use of the two-part coupled spindle, makes it easier to operate and reduces frictional wear. Furthermore, the tubular housing can be extended as required, which also makes it possible to increase the number of branching secondary lines. The vertical arrangement of the T-pieces makes assembly easy and, if repairs are necessary, the valve inserts can be easily replaced and the valve seats in the T-piece can be easily viewed, checked for any damage and reworked. This applies to both the vertical and horizontal installation position of the compact distributor.

Advantageous embodiments and constructive features of the invention result
from the subclaims.

The compact distributor has a one-piece, tubular housing (1) that has flattened surfaces on the sides at a specified distance. The housing (1) is connected to a central line at the ends. If the compact distributor is located at one end of a central line or container and samples are taken via the branching secondary lines or test pressure gauges are attached, one end of the tubular housing can be closed. The holes for the outlets and the sleeves (1.2) for welding in the T-pieces (1.3) are made on the flattened sides (1.1) of the tubular housing (1). The outlets (1.2), which branch off at right angles from the housing (1), are arranged in the X plane. If necessary, the outlets (1.2) can also be arranged offset without any problem.

At the location of the paired outlets (1.2) there are two T-pieces (1.3) arranged at right angles, which serve to accommodate the valve inserts with stuffing box packing (4) that are positioned vertically upwards. The inlet channel (1.4) of the T-piece (1.3) is connected to the tubular housing (1). The interior of the tubular housing (1) is closed off from the further secondary lines by the cone (2), which seals the valve seat (1.5) incorporated in the T-piece (1.3).

The cone (2) is attached to the lower spindle (7). The lower spindle (7) is guided in the head piece (47) in which the stuffing box packing (15) is accommodated and the inner contour is designed in such a way that it offers the lower spindle (7) a stop (57) in the open position. This stop (57) serves as a back seal and additionally protects the stuffing box packing (15).

The lower spindle (7) is guided through the head piece (47) and the stuffing box packing (15) in such a way that its end is in the coupling (8).

The coupling (8) accommodates the lower spindle (7) as well as the upper spindle (10) in its inner contour. The valve is operated by a handwheel (11) which is attached to the upper spindle (10). Rotary movements on the handwheel (11) are converted into lifting movements of the lower spindle (7). The linear movement of the lower spindle (7) minimizes friction in the stuffing box packing (15) and ensures that the valve inserts with stuffing box packing (4) move smoothly.

The upper spindle (10) is guided in the thread of the spindle nut (50). The spindle nut (50) accommodates the coupling (8) in its inner contour. It is advantageous if the pitches of the threads between the upper spindle (10) / spindle nut (50) and the spindle nut (50) / head piece (47) are the same. This means that the gland packing (15) can be re-tightened regardless of the valve position if the handwheel (11) is held and the spindle nut (50) is turned using the spanner flats attached to it. The lock nut (49) must first be loosened, as this acts as a safeguard against the spindle nut (50) being accidentally loosened.

The one-piece tubular housing (1) is provided with connection options (1.5) on its underside, which are located at the intersection points of the axes of the outgoing secondary lines. With these connection options (1.5), the compact distributor can be attached vertically or horizontally to a mounting plate (not shown) or similar base.
