Definitions

  • the invention relates to a device for a liquid discharge from a tub according to the preamble of claim 1.
  • the device may be used for discharging dirty oil from an oil pan of an engine block and cooling water of a radiator and oil of a drive box in the car.
  • a device for oil drainage from an oil pan of an internal combustion engine ( Catalog of Parts and Assemblies for YaMZ-240M2, 1989, p.53 ), which has a housing with a continuous threaded bore.
  • the threaded bore has a sealing plug with a sealing element.
  • the housing is hermetically welded to the oil sump.
  • the drain valve has a housing with an internal thread and a sealing element, which is arranged free at the bottom of the housing.
  • a stepped plug with a blind hole is screwed into the housing.
  • the blind hole communicates with the side surface of the plug by means of radial openings.
  • the sealing element When unscrewing the drain plug, a free space is formed up to the sealing element.
  • the sealing element itself is located at the bottom of the housing unattached, and on the element, the flow of the liquid to be discharged acts.
  • the unattached sealing member moves from hard material and shifts towards the opening under the action of the liquid to be discharged. This leads to abrasion and tilting and as a result to a liquid leak, whereby the reliability of the device is reduced.
  • an elastic sealing member which can dry and shrink during operation and shifts under the influence of fluid flow, wobbles and clogs the opening. This leads to jamming of the plug and liquid leakage, thereby reducing the safety of the device.
  • a reducer for attaching a drain hose is connected to the plug.
  • the housing is provided with a threaded shaft with a sealing ring for connection to a liquid container. This will reduce the number of Components of the device increases and this more complicated. Safety is reduced and the dimensions of the device are increased.
  • the device for draining liquid from a tub comprises a housing having an internal thread into which a plug having a step-like side surface is screwed in, and a blind hole through the plug which communicates through radial openings with a side surface of the plug, as well as with a sealing element.
  • the side surface in the upper step of the plug is provided with an annular groove for fixing and centering the sealing element.
  • the sealing element is installed in this annular groove with forced seat.
  • the annular groove in the upper step of the plug ensures the installation and fixing of the sealing element, which may be made of any material.
  • the annular groove comprises the sealing element even denser.
  • the device is compact and has a minimum number of components.
  • the device is thereby also simpler and more reliable.
  • the device comprises a housing 1 with an internal thread, a plug 2 with an external thread and a blind hole 3, which communicates through radial openings 4 with a side surface of the plug 2, and a sealing member 5.
  • the housing 1 is immovable and hermetically connected to a trough 6 for the liquid to be drained, z. B. welded.
  • the plug 1 is provided for installation of the sealing member 5 with an annular groove 7 in the upper step of the side surface.
  • the sealing element 5 is z. B. as a flat ring or O-ring made of an elastic material (rubber, polyethylene, polyurethane, fluoroplastics, leather, it-fabric, etc.) or of soft metal (copper, aluminum).
  • the sealing member 5 is made of a softer material than the material of the other components.
  • the sealing element 5 brings with screwed plug 2 a clear seal, if it is provided that the sealing member 5 protrudes on the bottom of the tub 6 facing side of the annular groove 7 and rests against an inner web 8 of the housing 1.
  • the radial openings 4 in the plug 2 are arranged below the sealing element 5 in the plug 2 and open into a gap 9 which is formed by a part of the plug 2 provided without external thread and the end face of the sealing element 5 protruding from the annular groove 7.
  • the radial openings 4 run diametrically to the blind hole 3 of the plug 2.
  • the protruding from the housing 1 part of the plug 2 is designed as a screw head 10.
