Definitions

  • the invention relates to corrugated pipes and corrugated hoses with fittings for connection between wire strands and assemblies or between assemblies with each other.
  • corrugated pipes made of metal such as low weight and high compressive strength are known. Also known is the fact that corrugated pipes are difficult to connect to the adjacent modules with the conventional mechanical engineering connection components. Furthermore, it is known that corrugated pipes are torsionally prone due to design. Therefore, with a permanent torsional stress caused by the installation conditions, material fatigue and subsequent destruction of the corrugated pipes or corrugated hoses must be expected. If corrugated pipes are used in installations with high safety requirements, a permanent torsional load must therefore be ruled out.
  • connection solutions that allow a reduction of the resulting torsional stress in a manufactured compound.
  • a guide component that is compatible with the wall profile should be able to be processed in conjunction with an elastic sealing ring.
  • the corrugated tube in the guide member remain torsion-free at least until the final tightening of the compound, but is tightened when tightening.
  • a sealing ring is intended to seal off the corrugated pipe to the connection component, while a crimping edge effects the axial securing by engagement in a corrugation valley of the corrugated pipe.
  • the corrugated tube thus connected to a connector can be compressed axially and then perform a rotational movement to a limited extent. If it comes to a permanent compression of the corrugated pipe, but the tightness of the connection is lost.
  • corrugated pipe according to the invention consists of the components according to the preamble of claim 1 and the embodiments according to the features of the characterizing part thereof.
  • the subclaims describe further preferred forms thereof.
  • corrugated pipe in the following description, this also applies equally to embodiments referred to as corrugated hoses.
  • the corrugated pipes described preferably relate to assemblies produced using metal corrugated pipes.
  • the invention is initially based on the assumption that a corrugated pipe is installed torsion-free only if it can still carry out a rotary movement after the tight fit of the connection. According to the invention this is achieved by a connector, the inner sleeve is firmly and pressure-tightly connected to the corrugated tube, while the outer member or an outer assembly is rotatably mounted on the inner sleeve and sealed against this. In this case, the seal is made between inner sleeve and outer component by means of sealing elements.
  • At least one intumescent seal is provided, so that an emergency sealing is ensured when the connection is overheated.
  • the corrugated pipes equipped according to the invention can be designed for connection to all known fixed or detachable connections. This requires only an adaptation of the geometry of the connecting pieces, in particular the geometry of the outer component or the outer unit.
  • a section of a corrugated pipe is machined at its end so that it has an approximately rectangular end.
  • the corrugated tube end and an inner sleeve are aligned coaxially with each other and firmly connected.
  • the fixed connection can be made in any way, provided that result of a tight connection. However, welding, soldering or gluing methods are preferred.
  • the junction is covered in a preferred embodiment by an over-pushed sleeve and protected against bending stress.
  • the pushed-sleeve can be firmly connected to the inner sleeve, wherein positive connections are just as suitable as welding, soldering or adhesive joints.
  • the sleeve can also take up and cover the end of the protective tube.
  • the inner sleeve of the connecting piece has on its outer side at least one annular groove for receiving an elastic sealing element.
  • an elastic sealing element Preferably, in this case, a round ring is used.
  • Another annular groove receives an intumescent sealing element.
  • This sealing element is not involved in the normal operation of the corrugated pipe to the sealing function.
  • the intumescent material is elastic in the normal state, it can also fulfill sealing functions.
  • the intumescent component can be of any type, provided that it has a fixed geometry in normal use, does not wear out and in use increases its volume by at least a multiple of the initial volume.
  • intumescent components of elastic mixtures in the initial state can be used as well as blanks of semi-finished products or pastes, which solidify after insertion into the groove.
  • the intumescent component before or after the round ring. There is only the requirement that a safe (emergency) sealing is achieved in case of loss of function of the circular ring.
  • the intumescent component can also consist of several parts that fill the groove completely or partially.
  • the inner sleeve has on its outer jacket means which, in conjunction with corresponding means in the bore of the outer member or an outer unit allow axial fixing or guiding thereof.
  • the inner sleeve has a groove for receiving a locking ring.
  • an outer member or assembly is pushed, wherein outer diameter of the inner sleeve and bore diameter of the outer member are paired with little play.
  • the bore of the outer member is also located outside the sealing area a groove corresponding in shape, dimensions and position to the groove of the inner sleeve.
  • the circlip is preferably a snap ring, but can also be filled by a punched wire filling the groove. It is possible to use components having the same effect, provided that an axial securing and at the same time a rotational movement is ensured between the inner sleeve and the outer component.
  • the inner sleeve has only one groove for receiving an elastic sealing element.
  • a sealing element of intumescent material is arranged on the front side of the inner sleeve and enclosed in the axial direction by an L-shaped ring with a projecting into the bore collar.
  • one end thereof is fixedly connected to a connection component, while the other end possesses the rotation-enabling connection pieces according to the invention.
  • This arrangement is sufficient for the reduction of possible torsional stresses. It is also possible to carry out both ends of the corrugated tube with the fittings according to the invention.
  • connection piece has an internal thread on the connection side, with which it is screwed tight against a connecting piece with a conical thread, for example a so-called RP thread.
  • a connecting piece with a conical thread for example a so-called RP thread.
  • Another design uses a sleeve which has an end opposite to the opposite connecting piece or - bore compatible form while it leads to its outer diameter by means of a federal there exists a Ü union nut, which serves to attach this connection.
  • Ü union nut which serves to attach this connection.
  • a loose flange or flange parts can be used instead of the union nut.
  • corrugated pipe according to the invention forms the corrugated pipe with the attached inner sleeves a rigid assembly.
  • connection to the corresponding line connections is then established.
  • the over-pushed sleeve can be provided with a threaded neck, forming ball or taper bushes, flange connections form or executed in the manner of the known quick-release couplings.
  • the corrugated pipe described above is exposed to excess temperatures in the region of one or both connecting pieces and if there is a risk that the sealing element used will lose its effect, the intumescent element will take effect and the sealing of the relevant connecting piece or line will be maintained.
  • the response temperature of the intumescent component can be selected such that swelling is reliably avoided in the operating temperature range, while the effect begins in good time before a lasting change in the material properties of the elastic sealing element.
  • the corrugated pipe according to the invention can also be designed so that at a line end, a terminal component of conventional type is used, while the second terminal end is designed in the construction described above. If a corrugated pipe designed in this way is first fastened to the non-rotatable connection part and then the rotatable connection part is connected, the freedom from torsion can also be ensured in this way.
