Description
Technical field
The utility model relates to a kind of jet shower bath, relates in particular to a kind of jet shower bath that is applied in the solar water heater water system, belongs to technical field of solar water heaters.
Background technique
Existing solar water heater mainly comprises pressure-bearing type and non-pressure-bearing type.
The working principle of pressure-bearing type solar water heater is: tap water enters water tank and heat pipe through control switch, heat collecting pipe absorbs after the solar radiation by medium gives cold water in the heat pipe with thermal energy transfer, water in the cyclic heating water tank, because water tank is the integrally closed structure, must open cold water inlet during use, eject hot water in the water tank with the hydraulic pressure of tap water, make hot water flow into water use sector from water outlet.The water tank of this kind structure bears the pressure of tap water, and water flow is relatively large, and comfort is better, but the water tank of this kind structure need bear the hydraulic pressure of 7MPa, and inside also need increase heat tube structure, higher to sealing requirements, material is thicker, thereby causes the cost of water heater higher.
The working principle of non-pressure-bearing type solar water heater is: tap water is connected to the intake-outlet (manger board) of water tank through control switch, until being full of water tank and glass heat pipe, water behind the glass heat pipe absorption sunlight in heating water chamber and the glass heat pipe flows to indoor water unit by intake-outlet again after the water in the water tank is heated and uses for the user.The water tank of this kind structure and glass heat pipe only bear the hydraulic pressure of water tank height, and pressurized is less, and therefore, glass heat pipe and water tank do not need withstand voltage design, economical with materials, and cost is lower with respect to pressure-bearing type solar water heater.But the solar water heater of this kind structure because the setting height(from bottom) of water tank is subject to building structure, generally is difficult to provide higher hydraulic pressure to water unit, causes the water flow of water unit less, influences comfort.
Chinese patent literature CN103016421A discloses a kind of liquid jetting device and has had the water heater valve of this liquid jetting device, belongs to non-pressure-bearing type water heater valve, and it has reached jet supercharging and the effect that reduces cost simultaneously by rational jet pressure structure is set.Yet, the disclosed water heater valve of the document, the bore of its nozzle is changeless, when adjusting hot water or cold water's flow of inlet water respectively by hot water or cold water's flow control valve, when the opening of cold water by-pass cock during less than the bore of spout, the hydraulic pressure of the working solution in the nozzle will be lowered, thereby make the jet velocity of cold water working solution reduce, effect of its suction hot water is bad, thereby comfort level is not high when causing use summer.

When swivel nozzle, needle-valve and nozzle together move, in this process, relative movement does not take place in nozzle and needle-valve, thereby make the sectional area of cooling water outlet remain unchanged always, like this, when the sectional area of cooling water inlet during less than the sectional area of cooling water outlet, the hydraulic pressure of nozzle inner cold water will be very little, be difficult to realize jeting effect preferably, and in order to guarantee jeting effect preferably, just need adjust needle-valve simultaneously, thereby the sectional area of cooling water outlet is reduced, and then require needle-valve and nozzle are regulated simultaneously, increase the use difficulty, then will not be difficult to guarantee water outlet effect preferably and higher comfort if do not adjust needle-valve and nozzle simultaneously.
From above argumentation as can be known, how water-mixing valve is improved so that its reach higher comfort simultaneously, lower user cost and operation comparatively easily is the technical barrier that also not have solution in the prior art.
