When connecting parts such as pressure gauges, vent valves or the like. to one under your pressure of a gas or one Liquid standing system results in the difficulty of gas escaping while the parts are being connected or to prevent liquid at the connection point.

The object of the present invention is therefore to create a nipple serving as an intermediate piece that closes automatically when parts attached to it are removed and opens again when new parts, such as pressure gauges, vent valves or the like, are connected to the system, thereby establishing a connection between the connected parts and the pressurized plant manufactures * at the same time, the inventive nipple should be simple in construction vmu Proposal has no difficulties in handling constitutes frosting,

To solve this problem, a nipple is proposed according to the invention, in which a sleeve with play is used., which under ier effect on the one hand against an upper collar of the sleeve and, on the other hand, against an inner cliulfcfcer abs nipple supporting the The compression spring surrounding the sleeve is arranged to be longitudinally displaceable and one of the nipples on its lower part in the system

end face to be used with a relaxed spring closing seal and lateral openings above the seal
having.

In an advantageous embodiment of the nipple according to the invention, the lower end of the sleeve is closed and
provided with a cover, the angled edge of which surrounds the seal formed as a ring.

The structure and the mode of action of the according to the invention Nipples should be based on the drawing ,; in the one preferred Äus Ausführungsbeispiel is shown. explained in more detail be, namely shows:

ig condition and

Fig. 2 is a longitudinal section through the nipple in the open State.

The tubular nipple 1 has at its lower end
an external thread 2 for fastening to a pressurized system, not shown, but can
also be provided with a plug connection. On the outer circumference of the nipple 1 is designed as a hexagon

Bund 5 is provided, which has a sealing ring 3 for sealing Connection to the mooring carries «. At its upper end, the nipple 1 has an internal thread 4 (or a similar connection possibilities) for the connection of Parts, such as pressure gauges, vent valves or the like. Mistake.

Inside the nipple, which is open at the top and bottom, 1 5 3o a tubular sleeve 6 used with play.

Between an inner shoulder 7 in the nipple 1 and one upper collar 8 of the sleeve 6 is a sleeve 6 surrounding Compression spring 9 arranged. This compression spring 9 pulls the lower end of the sleeve 6, which is closed, and a seal 11 carries sealingly against the lower end face 12 of the Nipple 1, This causes the nipple 1 to be relieved Drue * '' eder 9 closed. At the lower end of the sleeve 6 a cover 15 is attached, the edge 14 of which is angled is and the seal formed as a ring 11 receives.

Above the seal 11 there are openings 15 in the sleeve β intended.

When the nipple 1 is in the position according to Pig. I. in a system or pipeline under pressure ohi> connected manometer «or ventilation valve is located, it is closed under the action of the compression spring 9,

so that no gas or liquid can escape from the pressurized system or pipeline. If, on the other hand, a part, e.g. a manometer, vent valve or the like, is connected to the nipple 1 by screwing it into the internal thread h or <ä by another equivalent connection, the sleeve Γ, against its upper collar 8, is made of screwed-in part with its screw-in flange 16 ■ pushes, while compressing the spring 9 in the nipple 1 in the longitudinal direction of the same downward. This removes the seal 11 of the sleeve 6 from the lower end face 12 of the nipple 1, so that the pressurized medium in the system or pipeline can flow through the openings 1 *> into the interior of the sleeve 6 and thus reach the connected part.

If the part is removed from the nipple 1, the sleeve 6 moves again under the pressure of the spring 9 in the nipple 1 upwards until the seal 1. '. sealingly rests against the lower end face 12 of the nipple 1 and an outflow of gas or liquid from the system.

Appropriately, a stop shoulder 1 ″ ^{7 can be} provided inside the nipple 1, which serves as a stop for the collar 8 (see FIG. 2). [The openings 15 are at a certain distance above the seal 11 in FIG

is screwed or inserted into the nipple 1. This' effect can, however, also be ensured by the fact that

the collar S at a slightly larger distance from the upper

'edge of the nipple 1 is arranged.

The automatically closing Kippel ensures that When connecting or removing parts, e.g. pressure gauges, vent valves or the like, gas or liquid is removed a pressurized system or pipeline can only flow into the connected part if it is already is inserted into the nipple. As soon as the connection between the connected part and the nipple is released, prevents ^ i this an outflow of gas or air from the under

Pressurized system or pipeline. Since the closing or opening with the installation or removal of the to be connected Partly connected, incorrect operation is excluded and separate handling is superfluous. The nipple is simple in construction and therefore inexpensive to manufacture,
