Insulation box for shut-off and control valves

The invention relates to an insulating box for shut-off and control valves, which consists of two shell-shaped halves made of insulating material, which form an opening for the outlet of the valve actuating part.

The object of the invention is to equip the insulating box with a simply constructed, easy to handle and safe covering and sealing device in the area where the valve actuating part exits the box, so that the box keeps the actuating part encapsulated.

This object is achieved according to the invention by the characterizing features of claim 1, whereby the design features listed in the original claims also represent advantageous further developments of the solution to the problem.

The subject matter of the invention extends not only to the features of the individual claims, but also to their combination.

The invention encapsulates the valve actuation part emerging from the insulation box by means of a cover cap which is simple to construct, inexpensive to manufacture and easy to handle and is sealed by the box, whereby the connection between the cover cap and the insulation box is made by _{means of} a convenient bead-groove connection.

and the cover cap forms relatively large and secure sealing surfaces with the box.

The cover cap is also made of insulating material, which ensures perfect insulation of the fittings housed in the box and at the same time the easily removable cover cap provides easy access to the operating part.

The drawing shows examples of the invention, which are explained in more detail below.

Pig* 1 a part of an insulating box half in the area of the outlet of the valve actuating part with a cover cap covering this actuating part ,

Fig. 2 shows a part of the connection area between the insulation box and the cover cap in a further design.

The insulation box for shut-off and control valves consists of two shell-shaped halves (1) made of insulating material, which form an opening (2) for the outlet of the valve operating part (3).

In the area of this opening (2), a cover cap (4) covering the exiting valve actuating part (3) is held in a sealed and detachable manner by a bead and groove connection (5, 6).

The two insulation box halves (1) form in a preferred manner and as shown in the drawing in Fig. 1 a nozzle (7) which is formed around the opening (2) and projects outwards, which is covered by the cover cap (4) and in which the bead-groove connection (5, 6) is located in this overlapping area between the nozzle (7) and the cover cap (4). The peripheral surface of the nozzle (7) is provided on the outside with the peripheral

Nut (6) is formed and the cover cap (4) rests I on the front face of the nozzle (7) and engages with

"% of an external wall extension (8) (a I peripheral edge) above the supports (7) and äti this

I Wall extension (8) is on the inside all around the

jj This hood fastening method according to Fig. 1 and the

I Wall extension (8) with the bead-groove connection

I (5,6) and the

I Hood front surface (4a) represents a relatively

I In a further embodiment not shown

I the cover engages in the molded socket (7)

' also in the interlocking plug-in area of

I Hood (4) and nozzle (7). The groove (6) can be

I \) on the circumferential inner surface of the nozzle (7)

and mold the bead (5) onto the surrounding outer surface of the I cover (4).

■'] " It is also possible to form the bead (5) on the inside of the nozzle (7) and the hood (4)

&iacgr; on its outside with the circumferential groove (6)

to equip.

In another embodiment shown in Fig. 2, the box halves (1) are equipped without molded-on connectors (7) and the cover (4) engages

then directly into the opening (2) and in the area j

This opening contains the bead-groove connection (5, 6), ;

wherein the opening (2) on its circumferential surface

with the molded groove (6) or the molded bead

(5) and the cover (4) on the outside with the &igr;

molded bead (5) or molded groove (6) i

can be equipped. '

The valve operating part (3) with certain \

Distance covering cover (4) also consists \

&igr; made of insulating material.
