The top of the boiler main body (1) is provided with a control water tank (11) which is directly communicated with the boiler main body (1), the upper part of the control water tank (11) is provided with an atmosphere pipe (18) in which a float valve (12) is arranged. The utility model has the advantages of stable operation, simple installation and convenient repair.
Description
The utility model relates to a kind of heating system, particularly a kind of novel normal pressure (do not have and press) hot-water boiler heating system.
Normal pressure (do not have and press) hot-water boiler is a kind of heat power equipment that late nineteen seventies progressively grows up, and it is characterized in that boiler body moves under atmospheric pressure, and has fundamentally eliminated the hidden danger of the bursting of boilers.But at present normal-pressure hot-water boiler is to utilize float-controlled valve control system backwater mostly, reach boiler body and be in purpose atmospheric pressure under, and this heating system operation less stable, backwater control cabinet physical dimension is big, and installation and keep in repair equal more complicated.
The purpose of this utility model is to provide a kind of novel normal-pressure hot-water boiler heating system, and it is stable, and volume is little, installs simple, easy to maintenance.
Its solution is: at the backwater pipe end internally piloted valve is set.Be provided with and its control water tank that directly is communicated with at the boiler body top, the control water tank upper has air pipe.
Piston is arranged in the internally piloted valve, in the control water tank float-controlled valve is arranged, filling pipe and overflow pipe, there is the water level meter its outside; The automatic control water inlet pipe that between internally piloted valve and return pipe, has bypass to be connected, on the automatic control water inlet pipe control valve is housed, internally piloted valve links to each other with the float-controlled valve of control in the water tank by the automatic control outlet pipe, the automatic control water inlet pipe is identical with the automatic control diameter of outflow tube, its diameter is less than the return pipe diameter, boiler water inlet pipe is arranged on the internally piloted valve, and backwater directly enters the boiler body bottom by boiler water inlet pipe behind internally piloted valve.
Accompanying drawing is described an embodiment of the present utility model.
Fig. 1: be the utility model schematic diagram.
Fig. 2: be internally piloted valve of the present utility model and control cisten mechanism schematic diagram.
Fig. 1: the utility model is by boiler body (1), feed pipe (2), circulating pump (3), check-valves (4), heat-exchanger rig (5), expansion tank (6), automatic control water inlet pipe (8), internally piloted valve (9), automatic control outlet pipe (10), return pipe (20), boiler water inlet pipe (13) control water tank (11) and float-controlled valve (12) are formed.
Fig. 2: internally piloted valve (9) is arranged at return pipe (20) end, piston (14) is arranged in the internally piloted valve (9), system's backwater outlet (7), the automatic control water inlet pipe (8) that between internally piloted valve (9) and return pipe (20), has bypass to be connected, control valve (15) is arranged on the automatic control water inlet pipe (8), internally piloted valve (9) links to each other by the interior float-controlled valve (12) of automatic control outlet pipe (10) and control water tank (11), automatic control water inlet pipe (8) is identical with automatic control outlet pipe (10) diameter, its diameter is all less than return pipe (20) diameter, boiler water inlet pipe (13) is arranged on the internally piloted valve (9), and backwater is directly introduced boiler body (1) bottom by boiler water inlet pipe (13) behind internally piloted valve (9).The control water tank (11) that directly is communicated with it is arranged at boiler body (1) top, air hose (18) is arranged at control water tank (11) top, in the control water tank (11) float-controlled valve (12) and overflow pipe (16) are arranged, filling pipe (19), there is water level meter (17) its outside.
When system moves, start circulating pump (3), the interior hot water of boiler body (1) is drawn by feed pipe (2), control water tank (11) free surface descends, float-controlled valve (12) is opened, backwater enters internally piloted valve (9) again in automatic control outlet pipe (10) enters control water tank (11) by automatic control water inlet pipe (8), internally piloted valve (9) internal pressure disappears like this, system's backwater outlet (7) pressure is greater than internally piloted valve (9) piston upper chamber pressure, internally piloted valve inner carrier (14) is pushed and moves, internally piloted valve is opened automatically, backwater enters boiler body (1) bottom circulation by internally piloted valve (9) by boiler water inlet pipe (13) through return pipe (20), when the backwater amount of the output of boiler body (1) and boiler water inlet pipe (13) and automatic control outlet pipe (10) reached balance, system entered normal operation.
When circulating pump (3) when closing, backwater enters boiler body (1) and causes controlling the interior free surface rising of water tank (11), float-controlled valve (12) rises, when rising to designated water level, float-controlled valve (12) cuts out, be that automatic control outlet pipe (10) is closed, backwater no longer enters in the control water tank (11) from internally piloted valve (9), bear system pressure of return water in internally piloted valve (9) epicoele this moment, system's backwater outlet (7) is located pressure less than the pressure in the internally piloted valve (9), and piston (14) promotes to move down automatically to close, and backwater no longer enters boiler body (1), and reaching the purpose that system and boiler body are separated, system is out of service.
