Summary of the invention:
After taking following measures through my suggestion, this class fault does not again occur.
Water circulating pump by the outlet pipe reconfiguration to return pipe, effectively reduced the generation (in water at low temperature, gas is few) of vapour lock.
2. replace explosion-proof valve at exceedingly high pipe higher than water supply tank of boiler top installation, improved security.
3. when the angry resistance of boiler water temperature high yield, can change circular flow direction by valve, make its contrary circulation, with the gas pump back boiler, make gas pass through the exceedingly high pipe discharge on boiler top.
the utility model is comprised of boiler, motor, water pump, pipeline and some heating installation bags concretely, characteristics are: exceedingly high pipe is installed above boiler, exceedingly high pipe is a vertical and straight-through water pipe, the aspect ratio water supply tank is also high, the lower end is communicated with the highest point of boiler, the upper end is logical atmosphere directly, plays gas use in the discharge boiler, the boiler top is equipped with outlet pipe, outlet pipe is directly received upstairs from boiler, be connected with the threeway tube head, the threeway tube head is connected with heating installation bag upstairs, the other end of threeway tube head by vertical tube be connected the heating installation bag and connect, upstairs the heating installation bag be connected the heating installation bag and be connected with return pipe respectively by the threeway tube head, return pipe is connected with the bridge-type valve sets that four valves form by the threeway tube head, the bridge-type valve sets has four threeway nodes, wherein relative two threeway nodes, one end connects pump intake, one end connects pump outlet, relative two threeway nodes, one end connects boiler bottom in addition, the other end connects return pipe by the threeway tube head.
Being equipped with up and down on boiler, each two water pipes amount to four water pipes, the water pipe on top has outlet pipe, this outlet pipe no longer passes through water pump, but directly lead to upstairs from boiler, at first the water of boiler pass through outlet pipe and some threeway tube heads, is assigned to upstairs heating installation bag and heating installation bag downstairs, finally by return pipe, valve B enter water pump excessively, pump outlet is got back to boiler bottom through valve D, completes circulation.One, two water pipes of boiler bottom are the filling pipes on the left side, this filling pipe upper end is connected with water supply tank, the bottom is connected with boiler bottom, boiler the right water pipe is return pipe, be connected with valve D, valve A, chimney is to discharge flue gas, and firing door adds fuel and uses, ash-digging gate is used for clearing the ashes from a stove, and also can observe and manage combustion case by these two doors.
During normal operation, valve B, D open, and A, C close; When producing vapour lock, can at first turn-off the power supply of motor, water pump is stopped operating, then open valve A and C, valve-off B and D, connect at last motor power, water pump is started working, at this moment, the water of boiler bottom, A enters pump intake by valve, and the water under high pressure of pump outlet enters return pipe, heating installation bag and water inlet pipe back boiler through valve C, in the process of back boiler, with the gas one top lifting back boiler in water inlet pipe and heating installation bag, enter atmosphere through exceedingly high pipe, finally eliminated vapour lock.
The beneficial effects of the utility model are: effectively eliminated vapour lock, solved heating installation Bao Bure.
Description of drawings:
Below in conjunction with the accompanying drawings.Fig. 1 is outline drawing of the present utility model.
In figure: 1. water supply tank, 2. chimney, 3. exceedingly high pipe, 4. filling pipe, 5. outlet pipe, 6. heating installation bag upstairs, 7. return pipe upstairs, 8. heating installation bag downstairs, 9. return pipe downstairs, 10. valve C, 11. motor, 12. water pumps, 13. valve A, 14. valve D, 15. ash-digging gates, 16. firing door, 17. valve B, 18. boilers.
The specific embodiment:
The water pump 12 that heating system is originally driven by boiler 18, motor 11, pipeline 5,7,9 and some heating installation bags 6,8 form, originally water pump is arranged on outlet pipe 5, vapour lock often occuring cause water pump not work, cause that circulation does not freely cause final boiler 18 hydro-thermals, but heating installation bag 6,8 is not warm.
