Description
Technical field
The utility model relates to the technical field of temperature control valve, especially relates to a kind of boiler temperature control valve.
Background technique
Thermostat valve is the typical apply of flow control valve in domain of control temperature, and its basic principle is by control heat exchanger, air-conditioner set or other are with heat, cool equipment, once heat (cold) matchmaker inlet flow rate, to reach control apparatus outlet temperature.When load changes, by changing valve opening degree adjust flux, to eliminate the impact that fluctuation of load causes, make temperature return to setting value.Thermostat valve traditional at present in use, though control to reach stable state to the temperature by valve body, but its effect controlled is not fine, a large amount of gas is easily gathered in valve body, and gas cannot be got rid of in valve body, cause the temperature of thermostat valve itself to raise, make the detection data of temperature inductor can not reach better precision.
Model utility content
In order to steam in exits valve body, prevent the problem that temperature inductor correctness reduces, the utility model proposes a kind of boiler temperature control valve, comprise valve body, valve rod, described valve rod stretches into described valve body from described valve body top, described body wall is relatively set with cold water outlet and steam port, and described valve body lower portion is provided with hot water mouth; The valve rod of described valve inner is provided with sealing plug, and described sealing plug both sides are by described cold water outlet and the sealing of described steam port, and described valve rod stretches into described sealing plug, and end is provided with temperature inductor, stretches out described sealing plug.
Further preferred version of the present utility model, described steam port place is provided with air suction device.
Further preferred version of the present utility model, in the valve body of described cold water outlet and hot water mouth bottom, be provided with projection, described sealing plug is pressed on described projection.
Further preferred version of the present utility model, described sealing plug is quality of rubber materials.
Further preferred version of the present utility model, on the valve rod on described sealing plug top, cover has spring.
Further preferred version of the present utility model, is provided with fixed block in described sealing plug.
Further preferred version of the present utility model, described cold water outlet, hot water mouth, steam port inwall are provided with internal thread.
The boiler temperature control valve that the utility model proposes has following beneficial effect: during use, and good sealing effect, when temperature inductor detects that temperature is too high, internal pressure becomes large, is upwards pushed away by sealing plug, now, cold water outlet and steam port are opened, cold water pours into back balance temperature, and steam discharges by the air suction device of steam port simultaneously, after ensureing that inside temperature is stable, valve rod resets by spring, by cold water outlet and steam port sealing, structure is simple, good sealing effect.
