Definitions

  • the present invention relates to an electromagnetic flame safety valve that is incorporated into a housing of a domestic gas tap supplying a burner.
  • EP 1036987 A ( ES 2155016 A ) discloses a flame safety gas valve that is incorporated into a cylindrical housing of a domestic gas supply tap that comprises an electromagnet with a core and a movable armature, a protective casing inside which is housed the electromagnet, a shaft and a valve sealing member, wherein the sealing member is fixed to the end of the shaft, both extending outside the casing, a coaxial seat supporting the core of the electromagnet onto which is fixed the protective casing and a helicoidal return spring of the sealing member surrounding the valve shaft, the closed end of the casing having a guide hole adjusted for the axial movement of the shaft.
  • a safety valve of this type occupies a housing in the tap of an equivalent length, which increases the volume of the body of the tap and, as a consequence, the weight of the alloy employed in the manufacture of the gas tap.
  • the object of the invention is to provide a safety gas valve adapted in its length to be housed in a gas tap body that comprises an electromagnet with a core and with a movable armature, a valve sealing member connected directly to the movable armature, a protective casing that houses the electromagnet in its interior, and a return spring housed in the protective casing for the closure of the sealing member when the electromagnet is switched off.
  • the objective of this invention is to reduce the length of the safety valve of the prior art in order to reduce the volume of its housing in the tap body and thus, achieve a smaller tap body volume.
  • the safety valve according to the invention houses the return spring in the protective casing, instead of the spring being disposed between said protective casing and the sealing member as in known safety valves, and does not require, therefore, a valve shaft connecting the sealing member to the movable armature to guide the spring when said frame is moving.
  • the protective casing is formed by a tubular fixed element that comprises a housing for the spring and a tubular moving element that is supported on a internal end of the return spring, and may thus compress the return spring when the movable armature is attracted towards the core in the opened-valve position, or alternatively, said moving element of the casing is moved in the closed-valve direction by the effect of the force of the spring when the electromagnet is switched off.
  • the protective casing is formed by a tubular moving element and a tubular fixed element of a flexible material, such as elastomer, which has a central part reinforced internally by the return spring, with a bag-type geometry adapted to said spring.
  • the tubular fixed element is connected at its free end to the tubular moving element so that said tubular moving element may compress the return spring and the tubular flexible central part when the movable armature is attracted towards the core in the opened-valve position, or alternatively, said moving element of the casing is moved in the closed-valve direction by the effect of the force of the spring, when the electromagnet is switched off.
  • the protective casing is formed by a tubular fixed element that corresponds with a tubular wall of the metallic casing that houses in its exterior the core and a tubular moving element that is supported on an internal end of the return spring and may thus compress the return spring when the movable armature is attracted towards the core in the opened-valve position, or alternatively, said moving element of the casing is moved in the closed-valve direction by the effect of the force of the spring, when the electromagnet is switched off.
  • the electromagnetic safety valve 1 which is adapted to a gas tap body, comprises an electromagnet 2 with a U-shaped core 3 and a movable armature 4 attracted by the core, a sealing member 9 fixed directly to the movable armature 4 that effects a stroke "e" equivalent to the air gap of the electromagnet 2 when it is switched on to open the valve seat 20, a metallic casing 7 providing an electrical connection to the mass supporting the core 3, a protective casing 10 with a tubular shape that houses the electromagnet 2 by surrounding it, a helicoidal-type return spring 8 for the sealing member 9, which is housed in the protective casing 10, and an electrical connector 22 that supplies the electromagnet, wherein the safety valve 1 is incorporated in a housing 6 of the tap body.
  • the tubular protective casing 10 comprises at least one moving element, such as a moving hood 12, and a tubular fixed element 11 surrounding the core 3.
  • the tubular moving hood 12 made, for example, of plastic, has a free end closed by means of a closing wall 12a of the casing, this acting as a support fixed to the movable armature 4 and the sealing member 9 and moving with them in one or other axial direction.
  • tubular fixed element 11 and the moving hood 12 form the casing 10 that remains closed in all its positions relative to both parts 11 and 12, thereby ensuring the hermetic closure of the protective casing 10.
  • tubular fixed element 11 is opened at both ends, the free end of which has a collar 11a to allow it to be fixed to the metallic casing 7.
  • the fixed element 11 forms a concentric circular channel 14 delimited by a cylindrical interior wall 17 and a cylindrical exterior wall 16, through which the return spring 8 is guided and supported on.
  • the end of the moving hood 12b is connected to the fixed element 11 of the casing 10 in the hole between the exterior wall 16 and the interior wall 17 so that it slides on them easily when the movable armature 4 is attracted towards the core 3.
  • the moving hood 12 is supported and presses on one end of the spring 8 when it is driven by the movable armature 4 attracted towards the core 3, thereby compressing said spring 8.
  • the spring 8 is extended to drive the moving hood 12 in order to close the sealing member 9.
  • the moving hood 12 comprises on its opened end 12b a plurality of projecting radial flanges 18 that are inserted into corresponding windows 19 opened on said exterior wall 16 of the casing.
  • the tubular fixed element 11 is made of a material such as elastomer, and has a bag-type flexible central part 30, reinforced internally by the return spring 8 and with a geometry adapted to said spring 8.
  • the tubular fixed element 11 of the casing 10 is opened at both ends, the free end 15 of which has a collar 11a allowing it to be fixed to the metallic casing 7, and the other end comprises an interior radial flange 33.
  • the moving hood 12 comprises on the exterior wall of the opened end 12b a radial groove 31 in which the interior radial flange 33 is inserted so that the fixed element 11 and the mobile element 12 integrated into the protective casing 10 are solidly connected.
  • the protective casing 10 comprises the moving hood 12, the free end 12b of which has an interior radial flange 43, and a fixed element 11 that corresponds with a tubular wall of the casing 7, which houses and encloses the electromagnet 2, surrounding it.
  • the metallic casing 7 comprises a ring-shaped base 41 upon which is supported one of the ends of the spring 8, said tubular wall 11 being concentric to the ring-shaped base 41.
  • the tubular wall 11 guides the spring 8 internally and has on its free end an exterior radial flange 42.
  • the exterior radial flange 42 is inserted into the interior radial flange 43, said interior radial flange 43 being locked in place by its complementary exterior flange 42.
  • the interior radial flange 43 has a ring-shaped exterior surface 43a that is supported on the spring 8.
  • the spring 8 is housed on the exterior of the tubular wall 11 of the casing 7, prestressed against the ring-shaped base 41 of said casing 7 and with one of its ends positioned in a housing 45 delimited by the tubular wall 11, the ring-shaped surface 43a of the moving hood 12 and a peripheral radial tab 44 formed on the end 12b of said moving hood 12.
  • the sealing member 9 closes the valve seat 20.
  • the spring 8 is guided on the tubular wall 11 of the casing 7, prestressed against the ring-shaped base 41 of the casing 7. In this rest position, the movable armature 4 is separated from the core 3 of the electromagnet 2 leaving an air gap "e".
  • the moving hood 12 occupies an extended rest position with the exterior radial flanges 42 of the tubular wall 11 abutting against the interior radial flanges 43 of the moving hood 12, so that in said rest position, the valve seat 20 remains closed.
  • the electromagnet 2 is switched on in the opened-valve position, the movable armature 4 is attracted towards the core 3 of the electromagnet 2, thereby overcoming the resistance of the spring 8, so that the moving hood 12 is moved towards the core 3 by a stroke "e", thereby compressing the spring 8.
