Definitions

  • the invention relates to a safety gas flow controller consisting of a valve body, a control and adjustment mechanism arranged in the upper part of the valve body, which has a valve needle element, a safety valve, which is arranged on one side of the valve body, and a gas outlet shut-off mechanism.
  • the invention has for its object to propose a safety gas flow controller, which is designed and constructed in such a way that it effectively prevents gas leakage and one gas has exit safety mechanism, which ensures that the gas flow leading out of the gas container is also shut off when gas escapes.
  • the design and implementation of the safety gas flow controller should be simple and it should be possible to manufacture and produce in an economical manner.
  • a safety gas flow controller of the type mentioned is proposed, ° which is characterized by a tube with an incorporated passage, with an axial bore located at the bottom, and with radial bores which are arranged in the tube wall, a ball arranged inside the tube, a socket arranged on top of the tube with a central bore through which the valve needle element of the control and adjustment mechanism is guided and a seal in the upper part of the socket.
  • two seals are arranged on the valve needle element along its length, that a valve seat is provided with two recesses and with a central bore through which the valve needle element extends, that an end cap is provided with two projections, which engage in the recesses of the valve seat such that the end cap can be moved and moved axially relative to the valve seat, the end cap being provided with a central bore for receiving the valve needle element, that a spring is arranged between the end cap and the valve seat and that in the Central bore of the end cap, a fastener is mounted, which is screwed to the upper end of the valve needle element.
  • a rotary handle is arranged below the valve seat, which has a central bore for the passage of the valve needle element.
  • valve needle element is expediently passed through an adjusting element with a rotatable part.
  • a plug is non-positively connected in the axial direction to the lower end of the rotatable part.
  • the axial bore of the tube has a larger diameter than the radial bores.
  • the drawing - in particular FIGS. 1, 2 and 3 - shows that the safety gas flow controller includes the construction elements listed below: a valve body 1, an automatic gas outlet shut-off device 2, a regulating and adjusting mechanism 3, an adjusting element 5 and a safety valve 6.
  • the automatic gas outlet shut-off device 2 consists of a tube 21, a ball 22, a bushing 24 and a seal 25
  • the control and adjustment mechanism 3 includes an end cap 31, a fastening element 32, a spring 33, a valve seat 34 and a valve needle element 35. Two seals 36 are assigned to the valve needle element 35.
  • the safety valve 6 consists of a bushing 63, a spring 62 and an end cap 61.
  • the design and construction of the safety valve 6 are well known in the art and therefore need not be described in detail.
  • the valve body 1 has a bore 11 in its lower part, and likewise an outlet opening 12 which is connected to the bore 11.
  • the automatic gas shut-off device 2 is arranged in the bore 11.
  • the tube 21 has a passage 211 and also the two radial bores 213 and 214 in its wall. At the lower end of the tube 21 there is an axial bore 212. The diameter of the axial bore 212 is larger than the diameter of the two radial bores 213 and 214.
  • the bushing 24, which has a central bore 241 and a curved recess at the bottom, is on the top of the tube 21 arranged. A seal 23 with an opening 231 is inserted into the bushing 24.
  • the ball 22 is located in the passage 211 of the tube 21.
  • the seal 25 is arranged on top of the bushing 24.
  • the rotatable part 51 arranged in the middle of the adjusting element 5 is in threaded engagement with the adjusting element 5.
  • the lower end of the rotatable part 51 engages in the plug 4, while the upper end is provided with a turning handle 52.
  • the valve seat 34 belonging to the control and setting mechanism 3 has two recesses 341 on two opposite sides and a section 342 with a smaller diameter at the lower part.
  • This valve seat 34 is arranged at the top of the rotary handle 52.
  • the end cap 31 is placed on the valve seat 34 such that its projections 311 protrude into the recesses 341 of the valve seat 34.
  • a spring 33 is arranged between the end cap 31 and the valve seat 34 in such a way that the end cap 31 can be moved relative to the valve seat 34.
  • the valve needle element 35 is inserted through the central bore 312 of the end cap 31, the spring 33 and the central bore 521 of the rotary handle 52 into the central bore 511 of the adjusting element 5. The result of this is that the lower end of the valve needle element 35 extends into the central bore 241 of the bush 24, while the upper end of the valve needle element 35 is screwed onto the fastening element 32.
  • the central bore 511 of the rotatable part 51 is smaller than the central bore 41 of the plug 4.
  • the seals 36 are thus arranged in the region of the central bores 41.
  • the coil spring 33 acts with an upward force on the end cap 31, which in turn then in turn the valve needle element 35 pulls up. Because the seals 36 are larger in diameter than the central bore 511, the valve needle element 35 is prevented from being pulled out.
  • the seals 36 are also designed and designed so that they prevent gas leakage to the outside.
  • the lower end of the valve body 1 must be connected to a gas container (not shown) and the outlet opening 12 of the valve body 1 must be connected to a gas stove (not shown) via a rubber hose or a similar connection.
  • the rotary handle 52 is to be rotated, which in turn then causes the rotatable part 51 to rotate, as a result of which the plug 4 is raised and gas through the axial bore 212 and through the radial bores 213 and 214 of the tube 21 in the bore 11 can flow.
  • the axial bore 212 and the radial bores 213 and 214 are constructed and designed such that the flow rates flowing through are equal to one another.
  • the pressure outside the safety gas flow regulator is much less than the pressure inside the gas container, causing the ball 22 to be pressed against the seal 23 of the bushing 24. This prevents further gas leakage from the gas container.
  • the rotary handle 52 can be turned so that the valve needle element 35 can push the ball 22 down again and thereby open the passage 211.
  • Fastening element 32 can be arranged in a lower position so that the ball 22 remains in contact with the lower end of the valve needle element 35 and the passage thereby remains open.
