DE2430248A1 - Connecting ring for metal pipes - has rubber seal ring, holding ring and wedge cross section pressure ring - Google Patents

Abstract

The design is for metal pipes used in sanitary and heating installations. The advantages claimed are that the connection can be used for all sizes of pipes and for all the usual fluids. Installation is simple and cheap. The pipe (5) fits into a conventional muff or collar fitting (4). On the pipe there are three rings. The first is a flat rubber sealing ring (1). The second (2) is a holding ring V cross section and external anchor hooks. The third (3) is a pressure ring with wedge shaped cross section. This is forced into the V cross section of the holding ring and the inner surface of the latter presses against the rubber seal as the connection is made.

Description

Re .: Description and patent claim Title: Rohrverbi ndungsring for fTe tal l ronr (technical designation) field of application: The invention relates a connecting ring for connecting metal pipes in plumbing and heating installations.

Purpose: To connect the individual pipelines and fittings Technique: It is known that metal pipes in installations by means of fittings be joined together. To create a connection, either welding is carried out, screwed by thread, or connected to one another by compression fittings.

Criticism d. Stand d. Technology: It is necessary; 1. for threaded connections to make the thread by means of a thread cutting machine, the machine in all Cases must be carried (even in multi-storey buildings and with small repairs).

2. to transport the entire welding equipment during welding. aside from that skilled workers are required to carry out the welding work.

A compression fitting is for all larger dimensions of connections expensive.

The invention is based on the object of all complex device transports to avoid a simple implementation, possibly also by auxiliary staff can be run to allow. as well as a much faster execution of the work to ensure that these advantages save u @ a substantial amount of time and money To achieve cost savings.

Solution: According to the invention, the problem is solved by making the connection a.) from the pipe socket of the fitting u.

b. ) is made from the llohrverbindungsrin.

Obtainable advantages: The advantages achieved with the invention exist especially in it, ate only the fittings required depending on the size and diameter require a wet pipe connecting ring to make the connection between pipe parts and to manufacture fittings.

Description of an exemplary embodiment: An exemplary embodiment is shown in the drawing and is described in more detail below: For use this pipe connection ring must have the format piece without thread, but with a slightly wider socket than before.

Figure 1 shows: on the straight pipe part are in the following order pushed: 1. the press ring, 2. the pressure ring, 3. the rubber seal is the The rubber seal is only pushed halfway onto the pipe, the pressure ring is in it üoer advanced the rubber seal to the end of the pipe. It is then turned inside out overlapping rubber seals on the compression ring. Only the roiir is in the socket inserted and the press ring pressed in using special pliers.

Figure 2 shows that the pressure ring and the pressure ring on which there are small punched counter hooks are located, each pressed against the pipe or the socket. The counter hooks are attached in such a way that they cannot slip back out of the socket is. The rubber seal ensures the seal between the pressure ring and the fitting socket.
