Description

The radiator valve

Technical field

The utility model relates to a kind of heating device control valve, the heating device control valve that especially can regulate the room temperature automatically.

Background technique

At present, heating device control valve general on the market is regulated the size of control air flow passage opening and is regulated the air-flow size mainly by the switch of electromagnetic valve principle control air-flow by rotating machinery formula adjusting knob.Its control principle is to make solenoid closure connect air-flow by heating thermoelectric lotus root generation electric current; Otherwise when cutting off thermoelectric lotus root heating source, disconnect solenoid valve thereby the cooling of thermoelectric lotus root causes thermoelectric lotus root to produce undercurrent and cut off source of the gas, realize the purpose that source of the gas switches on and off.Its Principles of Regulation are by rotating machinery formula adjusting knob, and knob shaft is made the purpose that corresponding rotation (or sliding up and down) is regulated air flow passage realization openings of sizes by the adjustable lever that gear transmission (or other driving mechanism) drives the mechanical type valve.The bad point of general heating device control valve shows following several respects:

(1), in the solenoid valve unlatching process, throughput change by no moment increase do not have steadily excessive;

(2), when regulating the throughput size, the discontinuity of regulating because of mechanical knob causes the increase and decrease of throughput also discontinuous, not steady.

(3), make gas shock greatly, it is high that control valve integral body is required sealability, reduces working life because of the discontinuity of throughput changes.

(4), under equal conditions the discontinuous temperature-control performance that causes of adjustment process reduces, the unnecessary air-flow of waste part, capacity usage ratio is not high.

Summary of the invention

For the bad point that the discontinuity that overcomes existing general heating device control valve throughput control causes, the utility model provides a kind of heating device control valve that can regulate the room temperature automatically.This valve is in solenoid valve unlatching process, and throughput changes in the increase process the pressure buffer performance, and the throughput size adjustment can realize that uniformity is excessive.This radiator valve arrangement is simple, easy to use and the life-span is long; Safety, reliable can be saved the combustion gas resource simultaneously.

The technological scheme that its technical problem that solves the utility model adopts is: a radiator valve, constitute by knob (9), air flow stabilizing device (11), ignition (13), solenoid valve (14), flame-out protection device (15), servo valve assembly (18), temp controller (19), installation housing (22) and normal naked light device parts such as (23), it is characterized in that: dispose an air flow stabilizing device (11) on the valve seat body; Between air flow stabilizing device (11) and the control valve body by being threaded.

This air flow stabilizing device (11) can be realized steadily excessive performance of gas flow and pressure; Its working principle be when air-flow from suction port through out-of-date, give (7) active forces of stabilier, stabilier (7) passes to diaphragm (4) through connecting rod (6) after stressed, pass to spring (3) simultaneously, under the interaction of diaphragm (4) and spring (3),, thereby make the outlet side obtain a metastable air pressure by the size of control suction port aperture, to guarantee valve (radiator valve) outlet in the knob aperture from large to small the time, throughput also from large to small.

The beneficial effects of the utility model are, when satisfying existing general heating device control valve all properties, the pressure buffer performance is good in the throughput change procedure, and throughput size adjustment uniform and stable is excessive; This radiator valve is realized automation adjusting radiator firepower size; Simple in structure, easy to use and the life-span is long; Safety, reliable can be saved the combustion gas resource simultaneously.

Embodiment

In Fig. 1 when air-flow from suction port (8) through out-of-date, give (7) active forces of stabilier, stabilier (7) passes to diaphragm (4) through connecting rod (6) after stressed, pass to spring (3) simultaneously, under the interaction of diaphragm (4) and spring (3), size by control suction port (8) aperture, thereby make air outlet (9) end obtain a metastable air pressure, to guarantee valve (radiator valve) outlet in the knob aperture from large to small the time (or changing from small to big), throughput is (or changing from small to big) also from large to small.This air flow stabilizing device can be by regulating the requirement that its tail end adjusting screw (1) satisfies different Environmental Conditions and usability; Simultaneously also can be by regulating adjusting and the correction that its tail end adjusting screw (1) realizes steady air-flow performance.

In Fig. 2; its ignition operation principle is: at first push-turn key (10) makes push rod (12) back down solenoid valve (14); again by ignition (13) igniting; flame-out protection device (15) is lighted; and continue to push about 15 seconds; make thermoelectric couple be enough to make solenoid valve (14) adhesive by the electric current that heating is produced; take advantage of a situation again and rotate counterclockwise knob (10); until big fire position (about 180 degree); make combustion gas pass through nozzle mouth (15), lighted by Chang Minghuo device (23) simultaneously to the heating device firing chamber.

In Fig. 2, its current stabilization Principles of Regulation are: when gas constant-current stabilizer (11) is passed through in combustion gas, combustion gas is by automatic steady current, (its current stabilization principle is mode of execution explanation among Fig. 1) thus make burner obtain gas flow relatively stably, it is adjustable that this valve has 7 gears, when turning knob, gear (17) moves upward by the moving temp controller (19) of thread belt, driving under the spring force effect simultaneously draws pole (20) to move upward, and then drivening rod (21) is opened the valve port controller---servo valve assembly (18), thereby make combustion gas pass through the rising of gear (17) or the long aperture size of controlling servo valve assembly (18) that descends, the user can be according to the different requirements to ambient temperature, arbitrarily adjust the firepower size, convenient being suitable for.

In Fig. 2, its safety protection is implemented principle and is: when the burner accident extinguishing, Chang Minghuo device (23) will be automatically ignition combustion device once more, thereby guaranteeing that combustion gas is unlikely leaks, and has guaranteed user's safety; If Chang Minghuo device (23) is when extinguishing simultaneously; because the cooling of thermoelectric couple; make it supply with the undercurrent of solenoid valve (14); solenoid valve (14) will automatically reset in 10 seconds after flame-out; thereby cut-out fuel gas source; whole heating device is quit work, guaranteed leaking of combustion gas equally, accomplished best protection user security.

In Fig. 2, its automatically control implement principle and be: when room temperature reached the maximum temperature that valve sets, temp controller (19) expanded under temperature action, and its elastomer is increased, thereby servo valve assembly (18) is descended, until close port; When room temperature reached the minimum temperature that valve sets, temp controller (19) expanded under temperature action, and its elastomer is shortened, thereby servo valve assembly (18) is risen, and opened valve port, and until maximum, by this kind mode, this valve reaches the purpose of temperature control.
