Definitions

  • the present invention relates to a hose coupling and corresponding seal and in one aspect relates to a claw type coupling and seal.
  • Hose couplings are used for numerous applications in the transfer of fluids and compressed air. It is important to inhibit the escape of air or fluid at the junction point since any leakage can increase operational costs and pose a safety risk.
  • Claw couplings including type A (originating from Europe), type B (originating from USA) and Surelok couplings (developed in Australia), have been used for many years within the mining industry. Examples of improvements to these can be seen in specifications AU 716175, AU 713875 and AU 716392 made by the present inventor.
  • Another type of coupling commonly referred to as "Storz type” couplings, are used in high pressure water hoses, such as those disclosed in US 489,107 to C. Storz, US 4,523,778 to K. Ebert and US 4,886,303 to Carson et al. There are however a number of problems with these existing types of couplings and corresponding seals.
  • Both the claw and Storz type couplings use two like fittings that can be pushed together and twisted to engage a retaining means, somewhat similar to a bayonet mount.
  • a retaining means somewhat similar to a bayonet mount.
  • two rubber sealing rings are used, one in each fitting, which abut each other when the coupling is joined.
  • bellows type seals having a resiliently flexible portion may be used in these couplings as well as in the Surelok couplings.
  • the bellows seals include a toroidal portion that fits into a correspondingly shaped annular cavity in the side of the passageway of the fitting thereby providing a seal between the fitting and air or fluid path. The top of the seal abuts a respective seal in an adjoining fitting - thereby providing a sealed connection between the fittings.
  • the bellows seals can tend to leak as fluid or gas is able to move behind the lower edge of the seal and out between the edge of the coupling and the seal. This can lead to the creation of dust, mud and other problems which can hinder efficient work practices. This can also lead to increased operation cost and danger to personnel.
  • the bellows seals can blow apart. This occurs when the lower edge of the seal folds back upon itself resulting in a portion of the seal blowing out the side of the coupling or the seal otherwise become dislodged within the fluid passageway.
  • a hose coupling of unitary construction comprising a tail portion, a head, and a passageway passing therethrough, the tail portion configured for connection with a hose, the head being radially enlarged relative to the tail portion, and including an end face perpendicular to said passageway, claws extending outward radially and axially from the head for connection with a like coupling, whereby respective end faces of said hose coupling and like coupling abut, the hose coupling having a seal retaining groove extending inwardly axially of the end face and separated from the passageway by an inner wall, such that in use a seal located in and extending axially outwardly from the seal retaining groove is compressed by contact with an adjacent seal in said like coupling to form a sealed connection.
  • the tail portion may include ribs, teeth, male or female thread, or any other form of fixing means used on hose couplings for connecting a hose directly or indirectly thereto.
  • the seal includes an abutment portion protruding axially from the seal retaining groove, and a resiliently deformable portion for retaining the seal in the groove.
  • the resiliently deformable portion acts to anchor the seal within the groove to inhibit displacement therefrom due to the flow of gas or fluid through said passageway.
  • the extent to which the seal extends into the passageway of the hose coupling thereby constricting the passageway at the head, is less than 30% of the diameter of said passageway, or less than 20%, 10%, 5%, 2% or 1 %. This means that the exposure of the seal to the medium being transported through the coupling is reduced relative to conventional couplings to inhibit the adverse flow affects being produced within the flow path, such as turbulence.
  • the seal includes an annular elastomeric portion coaxial with a generally rigid ring, the elastomeric portion including an upper abutment portion for abutment with a seal of an adjoining like coupling body the lower resiliently deformable portion being locatable within said annual seal retaining groove, wherein the rigid ring in located adjoining or integral with said abutment portion, whereby the abutment portion is inhibited from deformation in a lateral direction relative the passageway.

  • the rigid ring is separated from the upper abutment surface by a 1 mm thick layer of the elastomeric material.
  • the inner boundary of the rigid ring is generally even with an inner boundary of the elastomeric portion to thereby inhibit the formation of turbulence in the flow path.
