Valve on a portable pressurized gas container

The invention relates to a valve on a transportable pressurized gas container for emptying the same, consisting of a valve housing ■ with one permanently attached to the compressed gas container Inlet connection, a drain connection and a Manually operated shut-off element arranged in the passage channel of the valve housing.

Such containers are used to hold pressurized gases, cooling gases and foaming agents for production determined by foams, etc. and also allow refilling of the when the valve is open Container through the valve.

The object of the invention is now a valve of the type specified in the preamble of claim 1 to improve with simple means in such a way that a re-

filling of the pressurized gas container is excluded, The solution to this task is characterized by a tubular adapter with one of the drainage ports the valve adapted and inextricably attached to the latter inlet, an outlet and with one arranged in the through-channel of the adapter between the inlet and the outlet, in the direction of flow towards the drain from the medium pressure influenced automatically opening, but in the opposite direction automatically closing shut-off device.

These measures now make it possible to use known ones that already exist in large numbers and, in accordance with a legal requirement, to convert valves that are no longer permitted with little effort so that that afterwards their application also with thin- ■ uanded and therefore only for, one-time filling approved pressurized gas containers is allowed.

It is beneficial in the sense of the task if the adapter and the valve drain connection by means of a screw connection are connected and that the latter through into the threads of the Screwed connection are secured against turning back.

A preferred embodiment form which is both favorable in terms of production engineering and is also not susceptible to malfunctions characterized in that the free end face of the valve drainage connection is designed as a valve seat is that a valve body, in particular in the form of a ball, in Longitudinal stretching of the through-channel is limited adjustable and that in the through-channel of the adapter a spring element resting against the valve body on the valve seat, in particular a compression spring is arranged, whose end part facing away from the valve body is attached to one in the passage channel of the Adapter arranged, inwardly protruding shoulder is supported.

A variant which may be preferred under certain circumstances is that between the free end face of the Valve outlet nozzle and one in the through channel of the adapter, protruding inwards Shoulder a flange of a tubular, tapering towards the adapter drain Body made of elastic material is tightly clamped and that the walls this body in the area of the tapered end part on the one hand tightly abut one another and on the other hand, influenced by the medium pressure elastically can be pushed apart and then release the flow of medium.

It is advantageous if the adapter drain has the same shape and dimensions as the valve drain connector is formed and preferably also the inlet and the outlet of the adapter are aligned coaxially to one another are arranged to also connect the converted valve to existing lines without additional To be able to connect funds directly.

Embodiments of the invention are shown in the drawing and are described in more detail below.
It shows: FIG. 1 a part of a pressurized gas container

Drain valve in the front view,

partially broken open;

Fig. 2 shows a further embodiment in the same view.

Both embodiments are roughly bottle-shaped Pressurized gas container 1, a manually operated valve 2 and a tubular adapter 3 together. Jas valve 2 has one at the mouth of the pressurized gas container r. 1 tightly closing and permanently connected inlet connector 4, one drain connector 5 and one not shown, by means of a handle 6 actuatable shut-off device, with which the passage of the valve 2 closed or can be more or less released for the removal of medium from the container.

In order to prevent the pressurized gas container from being refilled through the valve 2, which is not permitted by law, in both embodiments a tubular adapter 3 is attached to the valve outlet connection 5 in a tight-fitting and non-detachable manner.

For this purpose, the outlet connection 5 of the valve 2 has an external thread zone 7.

Furthermore, a threaded hole is provided in the inlet of the adapter 3, into which the outlet nozzle 5 of the valve 2 is screwed in.

Furthermore, the drainage connection 5 and the adapter 3 are made by adhesive introduced into the threads inextricably linked.

According to FIG. 1, the free end face of the valve drain connection 5 is also designed as a valve seat, with a tapered shut-off element 10 which can be adjusted to a limited extent in the passage 9 of the adapter 3 cooperates.
