Description
Art
The present invention relates to a kind of solar-heating device, specifically a kind of multifunctional safety valve.
Background technique
At present, along with the swift and violent upgrading with water heater product that improves constantly of living standards of the people, various electric water heater, Solar Enercy Fission Geyser, pressure-bearing water heater start to promote the use of gradually, their water tank generally all makes pressure-bearing type, suitable pressure is had during assure feed water, can effectively meet pressure needs, be particularly suitable for the tall building can not installing regular solar water heater at roof.Known water heater bearing type water tank, when just commonly using water, open tap water inlet valve, keep certain pressure of supply water, but during stopping water in order to prevent in water tank hot water return or tap water pressure too high time cause water tank to break, general timely closedown tap water inlet valve, when closing tap water inlet valve, because glassware for drinking water has stronger performance of expanding with heat and contract with cold, after the cold water in water tank is heated, larger pressure can be produced in water tank, water tank is caused damage, water tank can be caused during especially severe to break, some bearing type water tanks are also provided with general one-way relief valves at water tank bottom, when water tank internal pressure is higher, still safety protection effect is not had.
Summary of the invention
The object of the invention is: overcome existing water heater bearing type water tank and very easily produce because of overpressure the shortcoming that damage is even broken, heat exchange efficiency is low; a kind of multifunctional safety valve is provided, has that structure is simple, easy for installation, press-bearing water tank long service life, realize secondary safety protection, strengthen safety protection function, prevent from water tank from very easily producing damage because of overpressure the feature such as even breaking.
The technical solution adopted for the present invention to solve the technical problems is: this multifunctional safety valve, primarily of ball valve body, ball valve core, valve control device composition, it is characterized in that: described ball valve body is provided with side by side high pressure one-way relief valves, low pressure one-way relief valves, be provided with linked hole between high pressure one-way relief valves and low pressure one-way relief valves, high pressure one-way relief valves is provided with overflow hole; Described ball valve body is also connected with movable joint nut; Described ball valve core has overflow ducts.
The invention has the beneficial effects as follows: the multifunctional safety valve adopting said structure, when hot water is used, operation valve control device, make ball valve core be in opening state, tap water enters water tank through the water port of ball valve core, to make up in water tank the consumption of storing water, because the sectional area of water port is less, its flow lower than the flow of watering equipment, thus reduces the pressure in press-bearing water tank, achieves and subtracts hydraulic water.When stopping using hot water, operation valve control device, make ball valve core be in closed condition, overflow ducts aims at low pressure one-way relief valves, when the water heating temperature rising generation of press-bearing water tank is expanded and reaches certain pressure, water flows out from overflow ducts, promote low pressure one-way relief valves and open outflow, discharge through linked hole, overflow hole, realize low pressure decompression and safety protection, when hydraulic pressure is reduced to certain pressure, low pressure one-way relief valves is closed automatically; When the hydraulic pressure of press-bearing water tank acquires a certain degree; promote high pressure one-way relief valves to open; water flows out from high pressure one-way relief valves; discharge through overflow hole, realize high pressure relief and secondary safety protection, when hydraulic pressure is reduced to certain pressure; high pressure one-way relief valves is closed automatically; thus realize press-bearing water tank, subtract hydraulic water, low pressure operation.Have that structure is simple, easy for installation, press-bearing water tank long service life, realize secondary safety protection, strengthen safety protection function, prevent from water tank from very easily producing damage because of overpressure the feature such as even breaking.
As improvement of the present invention, described low pressure one-way relief valves is made up of one-way sealing packing ring, one-way valve push rod, spring, one-way valve pressure regulating screw, plug; Described high pressure one-way relief valves is made up of seal washer, one-way valve push rod, spring, one-way valve pressure regulating screw, plug, has raising safety protective effect, adapts to the feature such as different press-bearing water tank and pressure of supply water needs.
As a further improvement on the present invention, pressure switch is provided with in described ball valve body; Described valve control device is provided with electric controller, when hot water is used, water tank internal pressure is lower than after certain pressure, and pressure switch sends signal, start electric controller, automatic control ball valve core reaches opening state and supplies water, and when stopping using hot water, water tank internal pressure is higher than after certain pressure, pressure switch sends signal, start electric controller, automatically control ball valve core and reach closed condition stopping water supply, can effectively reduce manually-operated loaded down with trivial details.
As a further improvement on the present invention, described ball valve body is provided with one-way valve, effectively can prevent the hot water return producing press-bearing water tank because of tap water cut-off, ensures that press-bearing water tank is in water state all the time.
