DE7431646U - CONNECTION FOR HIGH PRESSURE PIPE FITTINGS - Google Patents

Description

The subject of the innovation are connections for high pressure pipe fittings, especially for connections with existing piping systems, e.g. according to DIN 3853.

The use of high pressure pipe fittings directly in existing piping systems, e.g. if there is a System show weak points, especially when using standardized screw connections, make suitable intermediate elements or Changes required »if you cannot replace the entire system want.

It is therefore an innovation to create connections which allow a simple connection with existing piping systems.

To solve this problem, connections are renewed Suggested for high pressure pipe fittings, marked by means of a standard fitting, the front end of which is inserted into a union nut is screwed in, wherein in a recess of the over-

union nut a clamping ring between a conical seat in the union nut and the front end of the standard fitting is provided and between the end and the cooperating therewith A seal is arranged on the surface of the clamping ring.

A special embodiment is characterized in that a sealing ring is used as an O-ring between conical contact surfaces is arranged at the front end of the fitting and the clamping ring in a recess of the same.

The characteristic of a further embodiment is that a sealing ring as an O-ring between lying perpendicular to the pipe axis Contact surfaces at the front end of the fitting and the clamping ring is arranged in a recess of one of these surfaces. With this design, a radially mountable butt joint is created.

In a modification of the connection is finally according to the renewal proposed that a sealing ring in the end of the fitting lying towards the seat surface between this and the clamping Intermediate pieces, which are supported on the seat surface, is arranged.

The advantages of the connection options according to the innovation are that the high-pressure connections in any existing piping system, in which elements according to DIN 3853 are used, can be used and thus high-pressure pipe screw connections be created that correspond to the extraordinary loads in this area.

In the attached drawings, those proposed according to the innovation are proposed Connections shown schematically in section. Show it:

Figure 1 shows a clamping ring with a conical attachment, Figure 2 a clamping ring with a straight attachment surface, Figure 3 shows another use of the clamping and sealing elements.

In Figure 1, the clamping and sealing elements are on a clamping ring 2 is connected to a standard fitting 1 via a conical extension 6 and is sealed there by an O-ring 4 known per se. The clamping ring 2 has a recess adapted to the sealing ring 3 at the opposite end. The bracing takes place a union nut 5, which takes all the elements in itself. Instead of the conical extension 6, as shown in FIG shows that the intermediate piece 2 can also be provided with a planar attachment surface 7, which creates a butt screw connection. All other elements remain unchanged.

Finally, FIG. 3 shows a solution that can be used, for example, due to a lack of space. Here the sealing ring 3 is the conical one Recess 9 of the standard fitting 1 adapted directly. The nut 5 is kept smaller in the wrench size than in using a banjo bolt.
