Definitions
- the invention relates to a control device for gas burners.
- Control devices for gas burners are known from the prior art well known.
- Known control devices for gas burners have a main valve, a servo valve and a Servo drive, wherein according to the prior art, the servo drive the setpoint adjustment and the regulation of a gas outlet pressure serves.
- control device is known from DE 100 26 035 A1 known.
- the control device for gas burners described therein has a main and a servo valve, with the servo valve the opening of the main valve is regulated.
- the gas outlet pressure is an actuator for the servo valve provided with an opening and closing of the servo valve with the appropriate frequency that can be modulated.
- a control device is known whose operating principle is shown in Fig. 2.
- This control device has via a main valve whose valve plate 21 with a Valve seat 22 cooperates and by a spring 30 in the Closed position is charged.
- the valve plate 21 is connected to a Membrane 23 connected above the first gas space 24th is provided.
- the gas flows from the inlet 34 into the second Gas space 25 and can with the main valve open in the third Gas space 31 continue to flow and from there to the outlet 35th Ist closed the main valve, a gas flow is prevented.
- In the closed position is the two-way valve 29, the electrically operable, in the closed position.
- gas flows over the first Gas line 27 and the second gas line 26 through the two-way valve 29 in the third gas line 28, in the third gas space 31 opens.
- the line section before the two-way valve 29 and through the two-way valve 29 has a certain flow resistance possibly influenced by a throttle 33 can be. Gas thus flows out of the first gas space 24 until in the first gas space 24 and in the third gas space 31 of the same gas pressure prevails. Furthermore, no gas flows over the first and second gas line 27, 26 in the first gas space 24th after, as this rather on the two-way valve 29 in the third gas line and thus flows into the third gas space 31.
- the Cross sections and flow resistance of the gas lines are like this tuned that the required and desired opening and Closing speed is reached.
- opening the two-way valve 29 the main valve is thus inevitably with a predetermined speed brought into the open position, whereas when closing the two-way valve 29 with the desired closing speed a complete closing of the main valve.
- a pressure modulation is therefore only possible when the servo two-way valve 29 operated pulsed is, whereby the pulse width can be modulated.
- the object of the invention is a control device for gas burners to provide with a main valve and a servo valve the in a relatively simple way a pressure modulation without Frequency modulation of the servo valve allows.
- the invention provides a control device for gas burners, the servo valve as a three-way valve device comprising, connected via gas lines to a first gas space is formed, which is essentially completed and via the pressure of which the main valve is actuated, which later explained in detail with reference to the concrete embodiment becomes. Furthermore, the three-way valve device with a second gas space in the inlet region of the control device connected and with a third gas space in the outlet of the Control valve.
- the three-way valve device can be replaced by a single Three-way valve or a corresponding combination of Two-way valves are created.
- the three-way valve device can be switched be that either the first gas space with the second gas space or the first gas space is connected to the third gas space.
- About such a circuit can be in a simple way the Control the main valve and beyond the opening cross-section to modulate the desired modulation of the main valve To achieve gas flow through the control device.
- the main valve by a corresponding pressure difference between the gas chambers and continue by means of a Spring loaded in the closed position and is by vacuum in the first gas space opposite the second gas space open.
- the main valve with a membrane in operative connection, which separates the first gas space.
- Fig. 1 shows a schematic diagram of the control device according to the invention.
- the gas flows from the inlet 14 to the second gas space 5.
- the valve plate 1 sits on the valve seat 2, the gas can not continue to the third gas space 11 and thus do not continue to the outlet 15.
- the gas flow is interrupted and the control device locked.
- the valve disk 1 is by means of a compression spring 10 in the closed position, therefore pressed on the valve seat 2.
- the valve disk 1 is in Active compound with a membrane 3, which in the upper part of Control device separates a first gas chamber 4.
- the three-way valve 9 is connected to three gas lines, the first of which Gas line 7 with the first gas space 4 above the membrane 3 connected.
- the second gas line 6 connects the three-way valve 9 with the second gas space 5.
- the third gas line. 8 Finally, the three-way valve 9 connects to the third gas space 11th
- the three-way valve switched so that the first gas line 7 and the second Gas line 6 are interconnected. Based on these Circuit results in a pressure difference between the first Gas space 4 and the second gas space 5, which together with the force the spring 10, the valve plate 1 of the main valve in the closed Holding position.
- the three-way valve 9 in a Position brought in which it is the first gas line 7 with the third gas line 8 connects. Through this connection, the Pressure in the first gas space 4 to the third gas space 11 and thus to Outlet side of the control device relieved. Due to the Flow resistance before the three-way valve 9 drops the pressure in front of the three-way valve 9 and the pressure in the first gas space. 4 is therefore rapidly degraded. Due to the resulting pressure difference between the first gas space 4 and the second gas space 5, the main valve is opened because the pressure in the second gas space 5 is higher than the pressure in the first gas space 4.
- the three-way valve 9 simply brought into the aforementioned position, in the first gas line 7 is connected to the second gas line 6 is. In this way, pressure is again in the first gas space. 4 built and the main valve closed.
- suitable intermediate position of the three-way valve 9 it is possible to have a certain Pressure difference between the first gas space 4 and the to adjust the second gas space 5. For this, the inflow of the Gas via the second gas line 6 and the first gas line. 7 in the first gas space 4 and the outflow of the gas over the third gas line 8 are adjusted accordingly.
- the flow cross sections through the gas lines and through the three-way valve 9 therethrough are as well as the flow resistances on the opening and closing behavior of the main valve Voted.
- To quickly open and / or close are basically large cross sections and low Flow resistances appropriate.
- the coordination of the cross sections and flow resistance must also be considered in terms of desired modulation behavior of the main valve done.
- the connection of the first gas space 4 with the second Gas space 5 must therefore in terms of cross-section and flow resistance on the opening behavior of the main valve especially be matched to the spring 10 and the membrane 3, to allow the desired modulation of the opening cross-section.
- a control device for gas burner with a Main valve and a servovalve actuated by an actuator, with which the opening of the main valve is regulated.
- the Servo valve is as a three-way valve device or double Two-way valve designed and connected via gas lines with a first gas space bounded by a membrane with the main valve is in operative connection, as well as a second Gas space in the inlet area and a third gas space in the outlet area connected.
