Definitions

  • the invention relates to a fitting with screw ring for screwing the fitting, e.g. to a valve stub, with a circumferential bead, which is engaged behind by at least radially inwardly projecting collar of the screw ring, and thereby transmits the tensile force of the screw ring on the fitting.
  • Fittings with a threaded ring for example for connection to a valve stub, then offer no assembly problem if the fitting is designed as a straight fitting or has only a slight curvature, so that it can be inserted through the threaded ring before attaching the fitting.
  • a screw ring is to be mounted rotatably but not removable on a fitting which expands further in the further course or is designed as a 90 ° bend, then the screw ring can not be mounted "from behind”. It is then dependent on a fitting of the type described in the introduction, the screw ring is mounted "from the front".
  • the threaded ring consists of two screwed together partial rings, the assembly is made so that first the first part of the ring is inserted from the front over the connection piece, then the elbows are inserted and finally the second part ring plugged and is bolted to the first part ring, wherein the two partial rings clamp the elbows between them.
  • connection is known in which a sleeve with external thread is pushed onto the end of the fitting and then two arcuate pieces are inserted into a circumferential groove of the fitting, which prevent removal of the sleeve. On the sleeve then a screw ring can be screwed.
  • this known connection is complicated to manufacture and difficult to assemble because of the bipartite nature of the screw ring.
  • a fitting with a threaded ring wherein the fitting has a circumferential groove, in which two inserts are used, which are overridden by a collar of the screw and behind, so that the tensile force of the screw ring on the fitting can be transferred.
  • the fitting requires sufficient space behind the circumferential groove, so that the threaded ring can be pushed so far onto the fitting, that the inserts can be inserted into the circumferential groove.
  • this required for the sliding of the screw ring straight section is sometimes undesirable.
  • the invention has for its object to provide a fitting that does not have these disadvantages.
  • the fitting according to the invention thus has the advantage that the threaded ring mounted from the front and that the fitting can be attached in any angular position on the valve stub.
  • the invention can be realized not only on curved but on any fitting, even in fittings in which the screw ring is pushed from behind. If e.g. When installing the fitting at the end of a pipe forgotten to postpone the screw ring before, so this can now be done later, since it can be mounted from the front.
  • the fittings can be sold entirely without a threaded ring so that they can be fitted with any desired threaded ring, e.g. with screw rings for fork wrench or hook wrench or for manual assembly.
  • the screw ring can be plugged directly behind a bend on the fitting. It does not require a straight pipe section.
  • a simple manufacture and storage of the ring parts is achieved in that they are the same. It then only requires ring parts of different diameters, i. for fittings with different diameters, or ring parts for different tools, e.g. Fork wrench, hook wrench etc ..
  • the ring parts have means for mutual anchoring.
  • the means are integrally formed on the ring parts or formed as separate anchoring components.
  • the necessary for a secure screw connection of the ring parts is made, so that the fitting can be screwed as usual to other, fluid-carrying facilities.
  • the ring parts have at least one axial receiving opening which is open in particular to the screw-on side. This receiving opening serves to receive an anchoring component with which the individual ring parts are connected to each other after placement on the fitting.
  • a sleeve can be inserted as an anchoring component in the receiving opening.
  • the receiving opening is slit-shaped. This means that after placing the ring parts only the anchoring member must be used to connect the ring parts together.
  • a tool can be used, with which the mutual anchoring of the ring parts is solvable.
  • the anchoring member can be pulled or pushed out of the ring parts, so that the ring parts are separated again from each other and can be removed from the fitting.
  • the anchoring member is made of metal, so that large forces can be absorbed.
  • FIG. 1 is a perspective view of a fitting according to the invention
  • Figure 2 is a plan view of the fitting in the direction of the arrow II in Figure 1;
  • FIG. 3 shows a longitudinal section III-III according to FIG. 2;
  • FIG. 4 shows a view in the direction of the arrow IV according to FIG. 3.
  • the drawing shows a fitting, generally designated 10, which is connected to other components carrying fluids, e.g. a valve stub can be screwed.
  • a screw ring 12 is used, which is screwed onto an external thread on the other component.
  • the screw ring 12 at its end facing the other component an internal thread 14 and for attachment to the fitting 10 a radially inwardly projecting collar 16.
  • This collar 16 engages behind a provided on the fitting 10 circumferential bead 18, which projects beyond the outer circumference of the fitting 10.
  • This peripheral bead 18 is engaged behind by the collar 16.
  • the circumferential bead 18 has a radially outwardly directed surface, which does not positively connect with the internal thread 14 of the threaded ring 12.
  • the screw ring 12 is divided into two ring parts 20 and between the ring members 20, a gap 22 prevails, i. the two ring parts 20 are spaced from each other.
  • the parting plane 24 thus extends in the radial and axial directions.
  • the two ring parts 20 can be joined in the radial direction.
  • the ring part 20 has a blind hole-like receiving opening 26.
  • This receiving opening 26 runs in the ring member 20 and is open to Anschraubseite. It serves to receive an anchoring component 28, which is designed as a sleeve 30.
  • the slot-shaped receiving opening 26 extends over 85% to 90% of the total length of the screw ring 12, so that the inserted sleeve 30 completely covers the region of the internal thread 14.
  • the sleeve 30 also covers the area in which the collar 16 engages behind the peripheral bead 18.
  • the two ring members 20 are connected together and secured to the fitting 10 after the two ring members 20 have been radially placed on the fitting 10 such that the collar 16 engages behind the peripheral bead 18.
  • the threaded ring 12 can therefore also be fastened to fittings 10, if immediately following the peripheral bead 18 a curvature or pipe expansion follows, which does not permit a displacement of the screw ring 12.
  • the sleeve 30 is inserted by means of a suitable tool in the receiving opening 26. By means of another tool which engages in the gap 22, the sleeve 30 can be removed again from the receiving opening 26, whereupon the screw ring 12 can be opened.

Abstract

L'invention concerne un raccord (10) comprenant un anneau fileté (12) servant à visser le raccord (10), par exemple sur un ajutage de valve, comprenant un boudin périphérique (18) en contact, par l'arrière, avec un collier (16) de l'anneau fileté (12) faisant saillie radialement vers l'intérieur, la force de traction de cet anneau fileté (12) étant ainsi appliquée sur le raccord (10). L'anneau fileté (12) peut être divisé en au moins deux parties d'anneau (20), pouvant être soulevées ou retirées dans la direction radiale, au moyen d'au moins deux joints de séparation s'étendant dans la direction axiale.
