Description
Technical field
The present invention relates to a kind of jet mixer for liquid, particularly relate to a kind of jet mixer for liquid being applied in solar water heater water system, belong to technical field of solar water heaters.
Background technology
Existing solar water heater mainly includes pressure-bearing type and non-bearing type.
The operation principle of pressure-bearing type solar water heater is: tap water enters water tank and heat pipe through controlling switch, the cold water that thermal-collecting tube transfers thermal energy in heat pipe by medium after absorbing solar radiation, water in cyclic heating water tank, owing to water tank is integrally closed structure, cold water inlet must be opened during use, eject the hot water in water tank with the hydraulic pressure of tap water, make hot water be flowed into water use sector from outlet.The water tank of this kind of structure bears the pressure of tap water, and water flow is relatively large, and comfort is preferable, but, the water tank of this kind of structure needs to bear the hydraulic pressure of 7MPa, and inside also needs to increase heat pipe structure, higher to sealing requirements, material is thicker, thus causes the relatively costly of water heater.
The operation principle of non-bearing type solar water heater is: tap water is connected to the intake-outlet (water fender) of water tank through controlling switch, until being full of water tank and glass heat pipe, glass heat pipe absorbs sunlight post-heating water tank and the water in glass heat pipe, flows to indoor water unit for user by intake-outlet again after the water in water tank is heated.The water tank of this kind of structure and glass heat pipe are solely subjected to the hydraulic pressure of tank height, and pressurized is less, and therefore, glass heat pipe and water tank need not pressure design, save material, and for pressure-bearing type solar water heater, cost is relatively low.But, the solar water heater of this kind of structure, owing to the setting height(from bottom) of water tank is limited to building structure, general being difficult to provides higher hydraulic pressure to water unit, and the water flow causing water unit is less, affects comfort.
Chinese patent literature CN103016421A discloses a kind of ejector and has the valve for water heater of this ejector, belongs to non-pressure-bearing type water heater valve, and it is by arranging rational jet flow pressurizing structure, has reached jet flow pressurizing and the effect reducing cost simultaneously.But, valve for water heater disclosed in the document, the bore of its nozzle is changeless, when being adjusted the flow of inlet water of hot water or cold water respectively by hot water or cold water's flow control valve, when the opening of cold water regulation switch is less than the bore of spout, the hydraulic pressure of the working solution in nozzle will be lowered, so that the jet velocity of cold water working solution reduces, the effect of its suction hot water is bad, thus when causing use summer, comfort level is the highest.
Chinese patent literature CN102086941B discloses a kind of water-mixing valve, including valve body, valve body cooling water inlet it is provided with on described valve body, valve body hot water inlet, valve body outlet and the nozzle being connected with valve body cooling water inlet, described nozzle is provided with nozzle cooling water inlet and nozzle cooling water outlet, the hot water regulation chamber being connected with described valve body hot water inlet and the mixed water cavity being connected with described valve body outlet it is additionally provided with in described valve body, described mixed water cavity is connected by being positioned at the valve body hot water outlet of hot water regulation one end, chamber with described hot water regulation chamber, and mixed water cavity is also connected by nozzle cooling water outlet with described nozzle.When needs adjust hot water flow, can precession or select nozzle in valve body, the sectional area of hot water inlet is decreased or increased, meanwhile, nozzle is also decreased or increased the interfacial agents of cooling water inlet, thus adjusts the mixed proportion of hot and cold water.But, in use there is following defect in it:
When swivel nozzle, needle-valve together moves with nozzle, in the process, there is not relative motion in nozzle and needle-valve, so that the sectional area of cooling water outlet is always maintained at constant, so, when the sectional area of cooling water inlet is less than the sectional area of cooling water outlet, the hydraulic pressure of nozzle inner cold water will be the least, it is difficult to preferable jeting effect, and in order to ensure preferable jeting effect, it is accomplished by adjusting needle-valve simultaneously, thus the sectional area of cooling water outlet is reduced, and then require needle-valve and nozzle are regulated simultaneously, increase use difficulty, if asynchronously adjusting needle-valve and nozzle, preferable outlet effect and higher comfort will be difficult to ensure that.
Knowable to discussed above, how water-mixing valve is improved so that its reach simultaneously higher comfort, relatively low use cost and advantageously operation be the technical barrier the most not solved in prior art.
