Definitions
- the present invention relates to union devices for pipe joints and more specifically to such a union, which keeps the pipes securely together on being joined, and where the union can only be disconnected using special measures.
- the present invention has the object of achieving such a pipe joint, which solves the problems mentioned above in a desired manner. This object is achieved by a union device of the kind disclosed in the claims, and what particularly characterizes the invention will also be apparent from the claims.
- Figure 1 is a perspective view of a locking ring used in the union device in accordance with the invention
- Figure 2 is an enlarged cross section through the locking ring of Fig. 1
- Figure 3 is a fragmentary section through the male and female part of a pipe joint intended for the union device in accordance with the invention
- Figure 4 illustrates a male and a female part at the beginning of fitting, with a locking ring placed in the female part, and
- Figures 5-7 show how the union is achieved during the fitting process.
- FIG. 2 there is shown a female part 1 and a male part 2 in fragmentary schematic cross section. From its outer radial end surface 3, the female part 1 has a first part 4 tapering to a decreased diameter inwards, a second part 5 in the form of a circular groove with a bottom parallel to the outside of the female part 1, and a third part 6 which is similarly tapered with reducing diameter inwards to terminate at a radially inwardly directed wall 7, in turn terminating at the inside 8 of the pipe.
- the male part 2 has to a large extent a configuration complemen- tal to the female part 1, so that it can be inserted in the latter. From its radially outward end surface 9 the male part 2 has a first part 10 complemental to the part 6 in the female part 1, a second part 11 which is an outwardly directed circular groove intended to be directly opposite the groove 5 in the female part, but having a first straight part 12 and a second tapering part 13, the male part also having a third part 14 complemental to the part 4 of the female part 1.
- the grooves 5 and 11 are intended to accommodate a locking ring, while the part 14 terminates in a radially outwardly directed end wall 15.
- the end walls 7 and 15 mate up with the end surfaces 9 and 13 respectively.
- male and female parts 2, 1 described here having tapering surfaces or parts, it will be understood by one skilled in the art that these can also have other configurations such as curved, cylindrical etc. without departing from the inventive concept.
- the locking ring itself is illustrated in Figures 1 and 2, and is to be accommodated in the grooves 5 and 11 when the union is made in the pipe joint.
- the locking ring 16 is conical with an outer surface 17 and an inner surface 18, these two surfaces being substantially parallel. At the narrow end of the inner surface 18 there is a short cylindri ⁇ cal part 19 and at the wide end of the outer surface 17 there is also a short cylindrical part 20.
- the ring 16 is suitably made from a plastics material and is comparatively rigid but with some resiliency.
- the ring 16 is also slit at 21 to facilitate its contraction when fitting the male and female parts into each other.
- the locking ring 16 is fitted beforehand into the groove 5 in the female part 1, where it is well protected from damage during storage, transport and fitting of the pipes.
- Figures 4-7 illustrate the fitting sequence.
- the male part 2 has begun to enter the female part 1 and has come as far as the locking ring 16. It is important here that the annular edge 22 forming the junction between parts 9 and 10 is within a diameter range permitting its entry into the conical opening of the ring 16.
- the locking ring 16 is pushed into the groove 5, as illustrated in Figure 5, to subsequently spring backwards again into the groove 11, as illustrated by Figure 6. Any attempt to pull the male and female parts apart is then prevented by the locking ring 16, as will be seen from Figure 7.
- the illustrated joint is comparatively tight with respect to penetrating contaminants.
- at least one flexible sealing ring must be inserted between the parts 6 and 10 and preferably also between the parts 4 and 14.
- the female part 1 is suitably provided with a through opening into the groove 5. A tool can then be inserted from the outside into such an opening for pulling out the locking ring 16 if a finished pipe joint must be opened.
- the invention has been described here in connection with pipes with a circular cross section. However, with the aid of simple methods it can be used for pipes having other cross sections, e.g. for pipes with a quadratic cross section.
- the male and female parts may then have the illustrated configuration, but the locking ring is provided with cuts at its corners. For removing such a locking ring when it has formed the union in the pipe joint, there should be an opening into the groove of the union device at each corner of the female part, so that the ring can be cut and pulled out. Such a square ring does not need to have any slit.
- the locking ring 16 may have one or more slits from its large end, but these are then not through slits, and they stop at a distance from its small end.
