Definitions

  • the invention relates to a hose connection assembly, which is used for the purpose of connecting the flexible hoses used in houses, workplaces, factories and similar areas to each other or to the installation.
  • the invention specifically relates to a hose connection assembly which is especially used for the purpose of connecting flexible hoses made of metal material to each other or to the installation, which prevents leakage of the material passing through the hose to the outer environment after connection and which is end-user friendly.
  • hoses made of different materials are used in many areas such as houses, workplaces and industry in order to transfer liquids.
  • the connection of the said hoses to each other or to the installation has great importance in terms of transferring the liquid passing through them in a correct manner and also in terms of safety. It is aimed to provide good impermeability during the transfer of the liquids or air by using connection apparatus for hoses and to prevent any loss of liquids or air.
  • the tightening bushing part is not fixed in the nut in the hose connection apparatus used in the current art. In a possible scenario, reverse positioning of the tightening bushing in the nut causes the connection to leak and for this reason, these hose connection apparatuses are inadequate in terms of impermeability.
  • the tightening bushing part is not fixed in the nut in the hose connection apparatus used in the current art. Assembly errors or leakage occur due to inadvertent positioning of the tightening bushing inside the nut in reverse (upside down), when the connection set has to be removed or prior to assembly.
  • the mentioned negative situations create extra labor need, extra costs, installation errors and even gas leaks depending on the location, and therefore; permanent solutions are needed for the impermeability problem.
  • difficulties are encountered in the mounting of the hose connection apparatus used to connect the hoses to each other or to the installation.
  • connection piece which is created to integrate two or more flexible hoses is made of hard plastic that may contain glass wool reinforcement. At least three teeth with rounded ends are made on each siphon in the connecting piece, to have a circular structure that surrounds the siphons all around.
  • the connector end interior is inclined toward an angle greater than 30 ° in order for the vertical surface between the fluid and the fitting and that allows the fluid passing through the hose to enter the fitting with a smooth and uniform flow, thus preventing pressurized fluid from entering between the fitting end and the flexible hose to create a surface that prevents fluid from passing through and to prevent the reduction of the velocity of the fluid generated by friction to create a surface that could cause fluid to enter the space between the fitting and the hose.
  • the present invention is used in splicing flexible hoses, no bushing and seal are used for joining and impermeability in the said application.
  • the present invention relates to a hose connection assembly, which fulfills the requirements mentioned above, eliminates all the disadvantages and provides some additional advantages.
  • the main aim of the invention is to prevent the leakage problem that occurs during the connection of the hoses to each other or to the related installation due to the fact that the tightening bushing part is fixed in the nut, contrary to the hose connection apparatus used in the current technique.
  • An aim of the invention is to prevent the occurrence of errors before or during mounting, due to the fact that the tightening bushing part is fixed in the nut, unlike the hose connection apparatus used in the current technique.
  • Another aim of the invention is to ensure that the tightening process performed by the end-user can be done in a practical way during the connection of hoses to each other or to the installation, and thus to provide an easy-to-install structure.
  • Another aim of the invention is to minimize costs and prevent waste with the hose connection element structure that can be removed from the product and installed back instead of replacing the entire product due to tightening bushing, unlike the hose connection apparatus used in the current technique.
  • the present invention is a hose connection assembly, which is used for the purpose of connecting the hoses used in houses, workplaces, factories and similar areas to each other or to the installation, comprising a nut into which a hose is positioned, a tightening bushing which provides impermeability and a nipple element which provides tightening after the connection to the nut is provided, characterized by comprising a seal which ensures that the end-user can insert the hose into the said nut without crushing or forcing and which provides an impermeability by preventing the liquid leaks.
  • Figure 1 is a general view of the hose connection assembly.
  • Figure 2 is a detailed view of the hose connection assembly nut screw socket, nut socket, tightening bushing, bushing tie piece screw pitch and bushing tie piece.
  • Figure 3 is a detailed view of the hose connection assembly.
  • Figure 4 is a detailed view of the hose connection assembly seal and the seal recess.
  • Figure 5 is a demounted view of the hose and the seal.
  • Hoses made of different materials are used in many areas such as houses, workplaces and industry in order to transfer liquids.
  • the connection of the said hoses to each other or to the installation has great importance in terms of transferring the liquid passing through them in a correct manner and also in terms of safety. It is aimed to provide good impermeability during the transfer of the liquids or air by using connection apparatus for hoses and to prevent any loss of liquids or air.
  • hose connection assembly (A) of the invention fundamentally comprises a nut (1), a nut screw socket (1.1), a nut socket (1.2), a tightening bushing (2), a bushing tie piece screw pitch (2.1), a bushing tie piece (2.2), a seal (3), a nipple (4) and seal recess (6) elements for the purpose of connecting the hoses (5), which are already connected to one another or to the installation, to each other.
  • bushing tie piece screw pitch (2.1) and bushing tie piece (2.2) elements on the tightening bushing (2) which provides the impermeability of the said hose connection assembly (A) structuring complex.
  • the said bushing tie piece (2.2) and the bushing tie piece screw pitch (2.1) on it are connected to the nut screw socket (1.1) and the nut socket (1.2), respectively.
  • the bushing tie piece (2.2) is rotated in a circular motion through the nut screw socket (1.1) by virtue of the bushing tie piece screw pitch (2.1) on it, and the connection process is carried out by making it fall to the nut socket (1.2). Once the said tightening bushing (2) completes this movement, it is mounted into the nut (1) in a manner which it cannot be demounted without being rotated.
  • the intermediate bushing element can also be used during mounting and it is removed from the configuration and it is made of plastic material.
  • the most important feature that separates the hose connection assembly (A) configuration from the connection elements in the current technique is that the tightening bushing (2) is inserted into the nut socket (1.2) in the nut (1) by rotating it by means of screw pitch. This ensures that the tightening bushing (2) moves freely in the socket while it makes it impossible for it to come out. In this way, faulty mounting due to incorrect placement of the tightening bushing is prevented and a high level of safe impermeability is provided.
  • seal (3) aims at both high-level sealing and ease of mounting for the end-user.
