Definitions

  • This invention is about pressure spring (1) for taps working with gas that can also adjust the level of gas.
  • This invention is about lifting an extra force exerted on the adjustment screw (2) during coming out of the gas on the adjustment screw inside the gas tap when gas is opened. This force is lifted completely after the forward pushing movement of the mile (3) through the adjustment screw (2) of the pressure power.
  • all the force exerted on the spring is to be transmitted through the adjustment screw (2).
  • Half gas passage through the system is on the adjustment screw. For this reason, the speed of flow of the gas (lt/h) displays variations during the passage of gas. This is an unwanted situation for the control fixings. This problem has been completely eliminated with this invention.
  • gas entry (4) and gas exit (5) In the furnaces operating in furnaces and ovens, basically there is on gas entry (4) and gas exit (5). These taps may rotate 160°C or more. It is provided that the gas is entered through the entry section (4) and that passage of the gas is provided through a male (7) inside the main body (6). The passage of the gas is provided through two holes on the male gas. One of the holes (8) provides full passage of the gas and the other hole (9) provides half passage. This hole is referred to as (9) pilot hole and provides an opportunity for the furnace to burn with low heat. An opportunity is provided for the furnace to burn under low heat by changing the diameter of this hole (9). The passage position of the gas is provided through the mile (3) on the tap.
  • the cam on the mile passes though the chip (10) on the male and provides that along with the mile, the male rotates as well.
  • the segment (13) on the mile helping to stop the forward movement on the mile from a certain distance. It comes to a position with the first large hole (8) of 90°C along with the male (7) and provides an opportunity for the full flow of the gas. If the mile (3) can be revolved for another 70° the tap shall come into a half open position. In this way the furnace or the oven burn with low flame.
  • the taps working with gas are generally divided into two groups.
  • first group of taps the passage of the gas cannot be adjusted inside itself.
  • These types of taps are generally furnace taps. There is no adjustment screw (2) in the furnace tap shown in Figure 2 and the passage of the gas cannot be made. This results with the condition that the tap cannot be transformed into different gas usages.
  • gases used in furnaces. The first one of these is LPG and the other one is natural gas (NG).
  • LPG(G30) gas is more intense than NG(G25 and G20) gas. Due to the differences of intensity of the gases, problems come out when taps working with LPG are supplied with NG. The oven would not burn as requested in such case. For this reason, adjustment screws (2) that can make adjustments inside the tap have been invented.
  • Adjustment screws are generally developed for second group taps, hence oven taps. Such taps in which adjustment screws (2) are used are referred to as oven taps. If we would refer generally to the use of adjustment screw (2), the adjustment screw, the adjustment screw, the adjustment screw is cylinder shaped, there is a clove in the external part and is general made of brass material. Its dimensions are quite small when compared with taps. The outer part is narrowed with reduction. There is a split for screwdriver (18) in order to make an adjustment on the upper part with a screwdriver. An o-ring hole (19) has been opened in order to place an o-ring on the middle part. On the outer part, there are wholes of 90° to each other. One of the holes is a hole to the breadth and from one side to another (11).
  • a specifically designed spring (1) which is not fully conic and can be integrated fully into the system has been designed.
  • this spring (1) a definite fixed spire (16) and the following spires (17) have conic position that shall not go through each other and shall be of the same linear shape requested.
  • the internal diameter of fixed spears (16) is greater than the largest diameter of the adjustment screw.
  • the fixed spears (7) are smaller than the male internal diameter (22). In this way, it is replaced inside the male.
  • the spears coming after the conic part (23) do not have any conic position and the external diameter is in a manner that can go inside the mile (3).
  • the internal diameter of the spring (24) is in a manner through which screwdriver can pass to adjust the adjustment screw.
  • There is a ⁇ angle (15) with spring conic having been determined according to the I-I axis.
  • This conic angle (15) has been designed in such a manner that the spring spires do not go through each other at this point and do not mount on the adjustment screw (2).
  • This spring used inside the tap system (1) does not exert any pressure on the adjustment screw in the event that the adjustment screw is pulled back to the maximum extent. In this position the adjustment screw (2) passes inside the spring (1) and shall be loosened from extreme load.
  • This spring (1) used in this invention is made of spring steel material and three fixed spears (16) have been used. The number of fixed spears may show differentiation depending on the type of tap to be used. At the same time, the ⁇ angle (15) to be used may also be changed.
  • This spring invented may be used for the gas control of household devices (1) and it can also be used in industry, for all taps working with internal adjusted screwed gas.
