Definitions

  • the invention relates to household gas valves with double security working together with a motor and solenoid coil that can be driven with electronic circuit, wherein there is a male which is used in tasks of regulating gas passing amount and which provides a gradual throttling of the fire as differently from the present condition. Additionally, there are at least two gas passing chutes in connection with the male on the body of the gas valve and gas passing is provided by turning of the said male placed on this body.
  • double output alternative structure of gas valve that is subject of the invention was designed in order that it is used in burners having multiple burning circles. Accordingly, a gas valve with an alternative structure comprises a male and a body with an alternative structure.
  • the gas valve in which the male with chutes that is subject of the invention is positioned is made of brass or aluminum material such as the present gas valves. Because these materials are durable to the conditions of tests and experiments specified in standards of EN 1106, EN 125, EN 126 etc. Each gas valve manufacturer applies these gas valves to the tests specified in these standards. The safety and reliability of the product are determined according to these tests.
  • the male that is subject of the invention is produced by machining method from aluminum or brass material.
  • US2013260327 which may be regarded as representing the most pertinent prior art, discloses a valve comprising a male provided with grooves and with holes for max and min flow settings, which is adjustable for NG and LPG use.
  • a further related valve is disclosed in European patent application EP2827060 A1 , describing a motor driven gas valve comprising a male provided with a groove and with holes for combustion gas flow control.
  • Another application with number PI 8500156 dated 14.01.1985 owned by Adolfo de Mitry relates to gas-operated ovens and gas valve that opens and closes gas passing on lighters of these and regulates the amount of gas between. Closure of said valve is by means of an elastic disc that functions for supply of gas from its center either in larger or smaller rates by virtue of closing a metallic center, thus allowing the flame to be eventually supplied either in high or low quantities.
  • a tapped globe valve manufactured in such manner that enables adjustment of the inner section of the center has been used in said application and said center has been equipped with an orifice that designate opening and closing of the valve.
  • Metal is not used at the inner sphere of the center of the elastic cap in order to provide a solution to the nonconformity arising from this gas valve comprising of a tapered shaft. Accordingly, our invention in question is also a different application than this application.
  • the aim of the invention is to introduce a dual-safety gas valve that contains a male that differs from the males of the prior art.
  • the aim of the invention is to produce male from aluminum or brass material that provides adequate mechanical and thermal strength at the existing gas valve standards.
  • Another aim of the invention is to have grooves on the male that are interconnected with the orifices that allow gas passage at the gas valve.
  • Yet another aim of the invention is to have at least two gas passage grooves interconnected with the grooves at the male on the gas valve body.
  • Another aim of the invention is to enable gradual adjustment of the fully open or choked position of the cooker.
  • Another aim of the invention is to introduce a gas valve in an alternate dual-outlet configuration and a male in an alternate configuration in compliance with the same.
  • Yet another aim of the invention is to design the gas passage groove at the single outlet gas valve body in alternate configuration such that it sees the full combustion orifice and the groove linked with the full combustion orifice; while designing the cross-gas passage groove to see the NG and LPG pilot holes and the grooves linked to such pilot holes.
  • the invention relates to a dual-safety gas valve that operates together with a motor and solenoid coil that can be driven with an electronic circuit at the household cookers, and said gas valve (1) basically contains a male (1.2) and a body (1.1) that accommodates a gas passage groove (1.1.1) and cross gas passage groove (1.1.2) interconnected with said male (1.2).
  • the motor rotates according to the data forwarded to the electronic card and such rotation movement thus ensures orientation of the gas passage as such movement is transferred to the male (1.2) positioned at the gas valve (1) by means of the gears on the motor.
  • the male (1.2) at the gas valve (1) of the invention contains, as distinct from the male at the current states (2), a full combustion hole (1.2.1) instead of multiple combustion holes (2.1), NG pilot hole, LPG pilot hole (1.2.3), Groove linked with the NG pilot hole (1.2.2.1) and Groove linked with the LPG pilot hole (1.2.3.1).
  • the gas burner cannot be turned down gradually, thus preventing achievement of homogenous transition between the flame intensities. This, in turn, leads to an instant deflagration of the flame.
  • the triangular groove linked with the full combustion hole (1.2.1.1) available at the male (1.2) of the invention not only allows gradual reduction of the flame slowly but also precludes deflagration of the flame.
  • the gas valve (1) body (1.1) is also redesigned according to the current state in compliance with the male (1.2) of the invention. Accordingly, there are multiple gas outlet grooves at the body (1.1).
  • the gas burner can be rendered suitable for use with the natural gas as the cross gas passage groove (1.1.2) sees the grooves (1.2.3.1) associated with the NG pilot hole (1.2.2) and the LPG pilot hole; and for use with the LPG as it sees only the LPG pilot hole (1.2.3.1).
  • the cross gas passage groove (1.1.2) at the body (1.1), on the other hand, is positioned so as to see the grooves linked with the NG and LPG pilot holes (1.2.2.1 and 1.2.3.1). In this manner, starting from the instant when the male (1.2) starts to rotate, gas flows from the groove linked with the NG pilot hole (1.2.1.1), and from the groove linked with the LPG pilot hole (1.2.3.1) after a certain position of the male (1.2), thus preventing flame deflagrations as experienced in the present state.
  • Minimum gas flow is provided when the rotation of the male (1.2) within the gas valve (1) is completed, and the gas burner burns at the lowest level and, at this stage, for NG, the gas flows from the groove linked with the NG pilot hole (1.2.2) and the LPG pilot hole (1.2.3.1) to the cross gas passage groove (1.1.2) and reaches to the gas outlet (1.1.4).
  • the gas flows from the LPG pilot hole (1.2.3) to the cross gas passage groove (1.1.2) and reaches to the gas outlet (1.1.4).
  • angles at the said male (1.2) that allows reaching to such positions where maximum and minimum combustions are achieved and illustrated in figure 6 at cross-sections F-F, G-G and H-H on the male (1.2) are angle “a” (1.2.1.2), angle “b” (1.2.2.2) and angle “c” (1.2.3.2), and their values are disclosed hereunder:
  • the angle “a” (1.2.1.2) between the groove linked with the full combustion hole (1.2.1.1) that allows maximum combustion at the male (1.2) and the full combustion hole (1.2.1) is in the range of 90° to 140°;
  • the angle "b” (1.2.2.2) between the groove linked with the NG pilot hole (1.2.2.1) and the NG pilot hole (1.2.2) that allows minimum combustion when NG gas is used is in the range of 90° to 140°;
  • the angle "c" (1.2.3.2) between the groove linked with the LPG pilot hole (1.2.3.1) and the LPG pilot hole (1.2.3) that allows minimum combustion when LPG gas is used is in the range of 90°
  • an alternate dual-outlet configuration of the gas valve (1) of the inception and the male in an alternate configuration (3.2) for use in such configuration has been designed for the purpose of controlling gas passage at the burners with multiple combustion rings.
  • the body of the gas valve (3) in alternate configuration contains gas inlet (3.1.7), first gas outlet (3.1.1), second gas outlet (3.1.3), inner ring gas passage groove (3.1.2), inner ring cross gas passage groove (3.1.3), outer ring gas passage groove (3.1.4) and outer ring second gas passage groove (3.1.6).
  • the male (3.2) in an alternate configuration contains the inner ring full combustion hole (3.2.1), outer ring full combustion hole (3.2.4), inner ring NG pilot hole (3.2.2), outer ring NG pilot hole (3.2.5), inner ring LPG pilot hole (3.2.3) and outer ring LPG pilot hole (3.2.6), and figure 14, figure 15 and figure 16 illustrates perspective views of the male (3.2) in alternate configuration.
  • passage of gas at the gas valve (3) in alternate configuration is as follows: gas from the gas inlet (3.1.7) passes through the inner ring full combustion hole (3.2.1) and the outer ring full combustion hole (3.2.4) at the male in an alternate configuration (3.2) and reaches to the first gas outlet (3.1.1) and the second gas outlet (3.1.3).
  • Figure 23 illustrates the male in an alternate configuration (3.2) at maximum combustion position and the location of the inner ring and outer ring gas passage grooves (3.1.2, 3.1.3, 3.1.5 and 3.1.6) at the alternate body (3.1).
  • Figure 25 illustrates the position of the male (3.2) in an alternate configuration when the outer ring ports are closed and inner ring ports burn at maximum position.
  • minimum gas passage occurs to the inner ring ports from the inner ring NG pilot hole (3.2.2) if NG is used, and from the inner ring LPG pilot hole (3.2.3) if LPG is used. The view that depicts this position is illustrated in figure 26 .
  • angle ⁇ (3.2.1.2) between the inner ring full combustion hole (3.2.1) and the full combustion groove (3.2.1.1) on the male in an alternate configuration (3.2) is in the range of 100° to 140°; angle ⁇ (3.2.1.2) between the inner ring NG pilot hole (3.2.2) and the inner ring NG pilot groove (3.2.2.1) is in the range of 100° to 140°,
  • gas valve (1) of the invention and the gas valve in an alternate configuration (3) can be attached to the gas distribution pipe (4) either as single valve or in multiple quantities. These situations can be seen at figure 27, figure 28 , figure 29 and figure 30 .
