Description

The invention relates to a device for protecting a manometer arranged on a container, the manometer being screwed into a manometer connection of the container via a connecting piece arranged on its rear side.

Containers that are filled with a fluid are often equipped with a pressure gauge to monitor the pressure inside the container, which is usually screwed into a pressure gauge connection of the container on the top of the container. Often, the manometer has a connecting piece on the back for screwing into the manometer connection, so that the display surface of the manometer is aligned approximately parallel to the tank surface. Since the manometer is located outside the container, a protective device for the manometer is required to avoid damage, especially during transport. Such a protective device usually consists of a protective bracket made of sheet metal, which is welded to the container wall. The assembly or welding of such a protective bracket is quite complex, and it is also necessary to check the tightness of the container again after the protective bracket has been welded on. In addition, the container can deform in the welding area, which makes subsequent processing necessary. In addition, such a protective bracket makes it difficult to paint the container. Furthermore, such a protective bracket can damage an adjacent container during transport.

Out DE 19 05 752 U a slotted manometer protection cap is known, but it is not suitable for the aforementioned containers. Out DE 77 02 245 U A fire extinguisher with a pressure gauge is known, the pressure gauge being provided with a protective cap. Such a design is also not suitable for the aforementioned containers.

The object of the invention is to provide protection for a manometer mounted on a container, which is easy to manufacture, assemble and disassemble and which protects the manometer against external influences, in particular during transport.

This object is achieved according to the invention in that the device is designed as a protective cap made of plastic and has at least two cap parts which are detachably connected to one another, the cap parts lying circumferentially on the pressure gauge and at least one cap part having an inside fastening element for fastening to the connecting piece and / or to the pressure gauge connection.

The device is thus designed according to the invention as a preferably two-part protective cap made of plastic, the cap parts being designed such that they bear circumferentially against the pressure gauge and protect it against mechanical impairments. The two cap parts can be easily attached to the connecting piece and / or the pressure gauge connection in a positive and / or non-positive manner and can also be removed again accordingly. The two cap parts can be easily manufactured, for example, by injection molding. There is therefore no need for any welding work on the container, the container does not have to be repainted and it is not necessary to check the container again for leaks after the device has been installed. In addition, there is also no risk that the mounted device will damage another container during transport.

In an advantageous embodiment, it is provided that two essentially identical cap parts are provided, which are detachably connected to one another via two snap connections. The two cap parts then differ only in the design or arrangement of the snap connection elements, so that they can in principle be produced in a single injection mold, which further simplifies production.

It is preferably provided that the inside fastening element is designed as a fastening clip.

In a further preferred embodiment, it is provided that, starting from its outer end face, the protective cap has a first inner cavity, the inner wall of which is adapted to the contour of the circumferential surface of the pressure gauge, the first inner cavity being formed with a support shoulder lying all around the rear of the pressure gauge passes a second cavity. This design ensures that any shock loads are absorbed by the device and do not act on the manometer.

Furthermore, it is provided that the inner wall of the second cavity is adapted to the contour of the pressure gauge connection for bearing against the pressure gauge connection. This ensures exact positioning on the container.

It is particularly preferably provided that the outer contour of the protective cap is hemispherical.

If the assigned container has a further valve in the area of the pressure gauge connection, it is preferably provided that the Protective cap has at least one recess on the outside for an additional valve of the container.

In an additional embodiment it can be provided that the first inner cavity can be releasably closed at the end with a closure cap.

The invention also relates to a container with a pressure gauge connection and a pressure gauge, the pressure gauge being screwed into the pressure gauge connection via a connection piece arranged on its rear side, the container having a device as described above.

The container can be, for example, an expansion vessel in heating systems or the like.
