Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1.
A kind of relay system double-source gas integrated valve, it comprises main pressure maintaining valve 1, main switch 2, double-air-supply nozzle 3, relay A4, ignition mechanism (PILOT) 23, low-pressure fuel gas pressure governor 16 and high-pressure gas pressure governor 18, and is as shown in Figure 1.The air-inlet cavity of main pressure maintaining valve 1 wherein is connected with gas inlet; The air-inlet cavity of main switch 1 is connected with the outlet chamber of main pressure maintaining valve 1, and the air outlet of main switch 2 is connected with double-air-supply nozzle 3; Relay A4 is used to control the pressure of back pressure chamber that main switch 2 is equipped with spring with the break-make of control main switch 2, thereby whether combustion gas gets in the double-air-supply nozzle 3.It is the controlling device of its break-make of adjusting of master with relay A4 that main switch 2 is connected with one; Main switch 2 back pressure chambers (promptly are equipped with a side of pressure adjusting spring; Cut off through epithelium between back pressure chamber and the suction chamber) first pipeline 5 that passes through be communicated with a gas-entered passageway of first air chamber 6; Another gas-entered passageway of first air chamber 6 is connected with the air-inlet cavity of main switch 2 through second pipeline 7; And the pipeline of second pipeline 7 is less than the caliber of first pipeline 5, and the outlet passageway of first air chamber 6 is connected with second air chamber 9 through the 3rd pipeline 8, and second air chamber 9 is provided with pressure relief vent 10; Pressure relief vent 10 is connected with the gas-entered passageway of double-air-supply nozzle 3, and the actuating member 11 that is used to control pressure relief vent 10 break-makes with relay A4 interlock is installed on the pressure relief vent 10.Realize the self adaption adjustment in order to improve main voltage stabilizing of the present invention according to different sources of the gas; Main pressure maintaining valve 11 of the present invention has utilized high pressure and low-pressure fuel gas voltage regulator design corresponding pressure-regulating device; The composition structure of pressure-regulating device is: the back pressure chamber that main pressure maintaining valve 11 is equipped with spring (promptly is equipped with a side of pressure adjusting spring; Cut off through epithelium between back pressure chamber and the suction chamber) be connected with a gas-entered passageway of the 3rd air chamber 13 through the 4th pipeline 12; Another gas-entered passageway of the 3rd air chamber 13 is connected with the air-inlet cavity of main pressure maintaining valve 11 through the 5th pipeline 14, and the internal diameter of the 5th pipeline 4 is less than the internal diameter of the 4th pipeline 12; The 3rd air chamber 13 is connected with the air-inlet cavity of low-pressure fuel gas pressure governor 16 through the 6th pipeline 15; The 7th pipeline 17 that passes through of the 3rd air chamber 13 is connected with the inlet end of high-pressure gas pressure governor 18, thereby the outlet side of described low-pressure fuel gas pressure governor 16 and high-pressure gas pressure governor 18 is adjusted through the corresponding pipeline self-adaptive pressure that is complementary with the combustion gas kind of realizing main pressure maintaining valve 1 back pressure chamber pressure that all is connected with the outlet chamber of main pressure maintaining valve 1.On the outlet side pipeline of said low-pressure fuel gas pressure governor 16 and/or high-pressure gas pressure governor 18, control switch 19 is installed.For control ignition device (PILOT) 23 or ODS system air feed, the outlet chamber of main pressure maintaining valve 1 of the present invention is provided with an aperture 20 of giving vent to anger that is communicated with ignition mechanism air-inlet cavity 21, and the relay B22 of its break-make of control is installed on the aperture 20 of giving vent to anger.
The difference of integrated valve of the present invention and existing integrated valve is; Existing integrated valve need be used the break-make of two electromagnetic valve gas circuits, the break-make of first electromagnetic valve PILOT, the break-make of second main gas circuit of control; But shortcoming is to need to use forceful electric power; In case have a power failure, integrated valve just can not be worked, and perhaps needs interface to be connected to a manually-operated gate.The present invention adopts the break-make of relay control gas circuit; The required electric weight of relay is less, but because the pressure ratio that relay produced is less, so can only control the small flow gas circuit; Like PILOT; As for the switch of main gas circuit, then need control the break-make of main gas circuit through a small flow gas circuit of main switch control loop of the present invention, as shown in Figure 1.
Working principle of the present invention is:
When the integrated valve suction port gets in the main pressure maintaining valve, and output to the air-inlet cavity of main switch 2 from the outlet side of pressure maintaining valve 1, this moment, relay A4 closed; Combustion gas gets into first air chamber 6 from second pipeline 7, and gets into the back pressure chamber and second air chamber 9 of main switch from first pipeline 5, and the pressure of epithelium both sides equates; Main switch is in closed condition, at this moment, if open relay A4; Pressure in first air chamber 6 discharges to second air chamber through the 3rd pipeline 8, and combustion gas gets in the outlet chamber of the main switch that does not have pressure through relief port 10, and the pressure of first air chamber is less than the pressure of main switch air-inlet cavity; Epithelium overcomes air outlet that the strength of spring opens main switch to the double-air-supply nozzle air feed; Meanwhile, relay B22 work is passed through to be its air feed the aperture 20 entering PILOT air chambers 21 from the part combustion gas that main pressure maintaining valve 1 comes out.The working principle of Here it is main switch of the present invention.
The pressure of main pressure maintaining valve 1 of the present invention carries out in the following manner; If what suction port connect is pressurized gas, then the 3rd air chamber 13 passes through the 5th pipeline 14 build-up pressures earlier, and feeds back to the back pressure cavity of main pressure maintaining valve and the entrance point of high-pressure gas pressure governor 18 through the 4th pipeline 12; Feed back to the outlet side realization pressure balance of main pressure maintaining valve 1 again from the outlet end of high-pressure gas pressure governor 18; If integrated valve inlet end pressure becomes big (little) during work, the stressed change of the epithelium of then main pressure maintaining valve 1 big (little) can cause the air outlet to become big; Pressure reduces (increase); This moment, the 5th pipeline 14 fed back to the back pressure chamber of epithelium with the pressure that produces through the 4th pipeline 12 immediately, made epithelium return to normal state, and meanwhile the delivery pressure of high-pressure gas pressure governor 18 changes; With the pressure of balance master pressure maintaining valve back pressure chamber, thereby the self adaption that realizes pressure is adjusted.
The present invention does not relate to all identical with the existing technology existing technology that maybe can adopt of part and realizes.
