Definitions

  • Screw connection to be attached to an opening of a container
  • the invention relates to screw connections to be attached to an opening of a container with the features of the preamble of claim 1, ie screw connections which are provided for establishing a connection between the interior space of the container and a fitting to be connected to it.
  • liquid level indicators which are arranged on tanks of construction site vehicles and which enable the level of the fuel tank or hydraulic oil tanks concerned to be checked.
  • level indicators and / or devices for temperature monitoring connected to the screw connection the relevant hole provided with the screw connection is arranged in the vicinity of the tank or tank bottom. In the event of damage, replacement of the fitting in question therefore forces the container or tank to be practically completely emptied.
  • the invention has for its object to provide a remedy here by creating a screw that allows a particularly simple and convenient replacement of the associated valve.
  • the banjo bolt not only functions as a connecting member that establishes a fluid connection to the valve, but at the same time as Mechanical actuator of a check valve, which only releases the fluid connection between the interior of the container and the fitting depending on the fixing of the hollow screw on the container. Because the non-return valve prevents the fluid connection between the interior and the outside of the container, if the mechanical positioning of the hollow screw is eliminated when the hollow screw is unscrewed, there is no need to empty or empty the container when changing or replacing the fitting concerned If it is a gaseous medium, at least to have to depressurize it, as is unavoidable when using the usual screw connections.
  • the figure shows a longitudinal section of an embodiment of the screw connection provided for the connection of a liquid level indicator.
  • the embodiment of the screw connection shown in the figure is provided for the connection of a liquid level indicator to a hydraulic tank, of which only a partial section of its container wall 1 is shown.
  • the lower end section of the liquid level indicator tube labeled 3 can be seen.
  • the display tube 3, which extends along the outside of the container wall 1, stands with the interior of the container via a connection piece 5, which is arranged on the shaft of a hollow screw 9, an inner bore 7 of the hollow screw 9 and an inner through bore 11 of a threaded sleeve 13 in connection.
  • the threaded sleeve 13 passes through a suitable opening 15 of the container wall 1 and has an external thread 17 which extends to the end 19 of the threaded sleeve 13 assigned to the interior of the container, and a flange-like extension 18 provided at the opposite outer end of the threaded sleeve 13.
  • the inner through bore 11 of the threaded sleeve 13 has an internal thread 14 in its outer bore section assigned to the outside of the container.
  • the inner bore section of the through bore 11 opposite the internal thread 14 is also provided with an internal thread 16, the diameter of which is smaller than that of the thread 14.
  • a thread washer 31, which is screwed into the end region of the internal thread 16, has openings 26, which form through channels between the interior of the container and the inner bore section 20 of the through bore 11 of the threaded sleeve 13.
  • the threaded washer 31 serves to support a valve spring 25, which is designed as a helical compression spring and urges a sealing cone 24 of a check valve located in the bore section 20 against a valve seat, which is formed by an annular shoulder 33 that narrows the through bore 11 in some areas. In its closed position, the check valve prevents fluid passage between the inner bore section 20 and the outer bore section of the through bore 11 of the threaded sleeve 13 located beyond the annular shoulder 33.
  • the latter outer bore section of the through bore 11 is not provided with the above-mentioned internal thread 14 over its entire length. Rather, this ends at a distance from the annular shoulder 33.
  • the narrowed, thread-free bore section serves as a guide for a thrust piece which is axially displaceable therein and which is provided for the mechanical control of the sealing cone 24 of the check valve.
  • the pressure piece has a disk 35 with openings 23 which allow fluid to pass through and a projection 37 which extends in the direction of the sealing cone 24 and which extends through the opening of the valve seat of the check valve.
  • the pressure piece formed from disc 35 and projection 37 is provided for interaction with the free end portion of the hollow screw 9.
  • their inner bore 7 serves to establish a fluid connection with the display tube 3, specifically via lateral branch bores 39, which are aligned with a central opening 41 of the connecting piece 5.
  • the connecting piece 5 is opposite the threaded sleeve 13 by an intermediate sealing ring 47 and opposite the hollow screw 9 by an outer 0-ring 48 cooperating with the head of the hollow screw 9 sealed.
  • the opening 41 of the connecting piece 5 is also sealed off from the inner wall of the indicator tube 3, which is placed on the lateral extension of the connecting piece 5 containing the opening 41, by a sealing ring 43.
  • the length of the hollow screw 9 is in the length in the unthreaded end region which fits into the narrowed bore section, in which the pressure piece formed by the disk 35 with the projection 37 is guided Dimensioned such that screwing the banjo bolt 9 into the threaded sleeve 13 leads to a displacement movement of the pressure piece in the direction of the sealing cone 24 as soon as the banjo bolt 9 is screwed in so far that a seal on the sealing rings 28 and 47 and the 0th -ring 48 enters.
  • the projection 37 of the pressure piece lifts the valve cone 24 off the annular shoulder 33 forming the valve seat, so that a continuous fluid connection between the inner end of the through bore 11, the inner bore 7 of the hollow screw 9 and the Opening 41 of the connector 5 until the indicator tube 3 is released.
  • the banjo bolt 9 is unscrewed and the mechanical release of the pressure piece (disk 35 with projection 37) caused thereby, the check valve switches automatically into the closed position by the sealing cone 24 resting on the ring shoulder 33 forming the valve seat due to the action of the valve spring 25 and / or due to the bias pressure in the interior of the container.
  • the length of the hollow screw 9 and the thickness of the sealing ring 47 are adapted to the length of the threaded sleeve 13, measured from the outer sealing surface on the extension 18 to the annular shoulder 33 serving as a valve seat, so that at Screwing-in movement of the hollow screw 9 lifts the sealing cone 24 from the valve seat by mechanical action via the pressure piece (disc 35 with projection 37) as soon as a sealing contact pressure begins to build up on the sealing ring 47 and on the 0-ring 48.
  • the further screwing-in movement of the hollow screw 9, in which the sealing ring 47 and the 0-ring 48 lead to the production of the complete one Sealing can be lightly compressed to a corresponding stroke length of the opening movement of the sealing cone 24.

Abstract

Un raccord à visser dans l'ouverture (15) d'un récipient afin de relier l'intérieur du récipient à une garniture extérieure, par exemple un indicateur (3) du niveau du liquide, comprend une soupape de retenue (24), (33) capable de fermer l'alésage débouchant (11) d'une douille fileté (13). Lors du processus de raccordement de la garniture, la soupape de retenue peut être mécanquement amenée à la position d'ouverture par le vissage dans la douille filetée (13) d'une vis creuse (9) en communication fluide avec la garniture à raccorder.
