Abstract
The utility model relates to a device capable of automatically regulating the water outflow temperature of a gas water heater. A temperature regulating hand wheel and a temperature regulating spring which is used for setting a temperature are installed outside a valve body, and a temperature sensing drive element, a valve rod and a conical valve disc are arranged in the valve body; a hot water passage and a gas passage are opened in the valve body; the temperature sensing drive element is installed in the hot water passage and can drives the valve rod and the conical valve disc to control the opening of a gas passage valve port, and the purpose of controlling the water outflow temperature of a gas water heater can be achieved.
Description
Technical field
The utility model relates to a kind of device that can regulate combustion vapour water heater water-exit temperature automatically, can make combustion vapour water heater water-exit temperature automatic stabilisation within user's range of set temperature.
Background technique
At present, the control of combustion vapour water heater water-exit temperature promptly when the user thinks that combustion vapour water heater water-exit temperature is too high, can be regulated vice versa by increasing inflow by manually control of user.When the user need carry out water yield adjusting, just must fire the adjusting of vapour air inflow simultaneously.The situation of hydraulic pressure and combustion steam pressure shakiness happens occasionally in life, sometimes in addition pressure surge frequent, it also is common occurrence that water consumption changes.Just there is following drawback in combustion vapour water heater present under above situation: 1, the frequent adjustment of water yield vapour amount is used to the user makes troubles.2, the increase and decrease inflow carries out temperature adjustment, has caused the waste of water resources and the waste of combustion vapour.Will cause personal injury to the user when user has little time to carry out the adjusting of inflow or can not strengthen inflow more when 3, raising as if water temperature.
Summary of the invention
User, energy saving, minimizing personal injury for convenience, the utility model provides a kind of heat-operated valve, no matter how the intake pressure and the combustion steam pressure of combustion vapour water heater change, how water consumption changes, this heat-operated valve can both make combustion vapour water heater water-exit temperature be stabilized in user's range of set temperature, has overcome existing combustion vapour water heater and can not carry out thermoregulator shortcoming automatically.
The technological scheme that its technical problem that solves the utility model adopts is: leave hot water entrance, combustion vapor inlet, combustion vapor outlet in a valve body, establish a valve port between combustion vapour is imported and exported, the valve port opening size is by the taper valve disc control that fuses with valve rod.By the temperature adjustment handwheel temperature adjustment spring is applied certain pretightening force (the given water-exit temperature that this pretightening force is corresponding certain) before use, at this moment the elastic force of temperature-sensitive driving element and temperature adjustment spring is in state of equilibrium.In use when combustion vapour water heater water-exit temperature is higher than setting temperature, temperature-sensitive driving element in the hot water access way will extend, the reaction force pusher ovable valve stem and the valve disc that overcome the temperature adjustment spring move down, valve port opening is reduced, corresponding combustion vapour flux reduces descends combustion vapour water heater water-exit temperature, the result that water-exit temperature descends makes the temperature-sensitive driving element shrink again, effect inferior pyramidal valve disc at the temperature adjustment spring rises again, water temperature will raise again (but can not be elevated to original temperature), after the adjustment period of passing through of short duration gradient of temperature like this, the elastic force of temperature-sensitive driving element and temperature adjustment spring (pretightening force) will reach state of equilibrium again, and water temperature also just returns to original setting value.
If actual water temperature is lower than set water temperature, heat-operated valve will carry out opposite adjustment process, and final water temperature also can return to original setting value.
The beneficial effects of the utility model are that no matter how the intake pressure and the gaseous-pressure of combustion vapour water heater change, how water consumption changes, this heat-operated valve can both make the gas water-heater water-exit temperature be stabilized in user's range of set temperature.
Description of drawings
Accompanying drawing is a sectional structural map of the present utility model.
In the accompanying drawing: 1. valve rod, 2. rubber seal, 3. valve port, 4. taper valve disc, 5. valve body, 6. temperature-sensitive driving element (memory alloy spring), 7. temperature adjustment spring (or claiming returning spring), 8. temperature adjustment handwheel, 9. hot water outlet 10. fires vapor inlet 11. combustion vapor outlets, 12. hot water inlets.
Embodiment
As shown in drawings, before use, rotation temperature adjustment handwheel (8) is set the combustion vapour water heater water-exit temperature of expectation: as if the water-exit temperature height of wishing, can increase the pretightening force of temperature adjustment spring (7), vice versa.
In use identical with set water temperature as actual water temperature, then the elastic force of temperature-sensitive driving element and temperature adjustment spring balances each other, and valve rod (1) is with respect to valve port (3) non-displacement, and valve port (3) aperture is constant.
If because of certain reason (reduces as hydraulic pressure, vapour pressure raises, water consumption reduces) make actual water temperature be higher than set water temperature, then be installed in hot water entrance (9,12) Nei temperature-sensitive driving element (6) extends because of temperature stress, the resistance that overcomes temperature adjustment spring (7) makes valve rod (1) drive taper valve disc (4) and moves down a segment distance, the aperture of valve port (3) is reduced, combustion vapour flux reduces, thereby water-exit temperature is descended, water-exit temperature descends temperature-sensitive driving element (6) will be shunk, the result who shrinks is that the aperture of valve port (3) has certain increase again, water-exit temperature has certain increase again, cause valve rod (1) taper valve disc (4) to descend (by test choose reasonable temperature-sensitive driving element, the elasticity coefficient of temperature adjustment spring and valve rod, the quality of taper valve disc, rubber seal can make temperature fluctuation be suppressed very soon with the frictional force of valve rod, reach state of equilibrium rapidly), after the adjustment period of passing through of short duration gradient of temperature like this, the elastic force of temperature-sensitive driving element and temperature adjustment spring (pretightening force) will reach state of equilibrium again, and water temperature also just returns to original setting value.
If actual water temperature is lower than set water temperature, heat-operated valve will carry out opposite adjustment process, and final water temperature also can return to original setting value.
Claims (2)
1. heat-operated valve, order is installed taper valve disc, temperature-sensitive driving element, temperature adjustment spring, temperature adjustment handwheel on valve rod, in valve body, open hot water channel and combustion vapour passage, open a valve port in the middle of the combustion vapour passage, it is characterized in that: the temperature-sensitive driving element places the hot water channel, and the taper valve disc places the valve port place between combustion vapor inlet and the combustion vapor outlet.
2. heat-operated valve according to claim 1 is characterized in that: the temperature adjustment handwheel connects with valve rod by screw thread, and the temperature adjustment handwheel can apply the water outlet water temperature of certain pretightening force with the setting temperature control valve to temperature adjustment spring and temperature-sensitive driving element.
