Description
Technical field
The utility model relates to the plumbing technical field, relates in particular to a kind of constant-temperature tap.
Background technique
Constant-temperature water faucet also can be called constant-temperature tap or constant temperature water mixing tap, and its effect is that cold water and hot water are mixed into the warm water that presets temperature automatically.Mixer tap the earliest is the Double-knob tap, and the user need to rotate the knob of controlling cold water and hot water and regulate the inflow of hot and cold water, thereby is mixed into the warm water that needs temperature; Second generation mixer tap is single-handled faucet, and its core is a ceramic plate temp regulating valve core, and user's temperature that handle can be regulated mixing water that swings swings up and down the size of handle cistern capable of regulating drainage rate.But when the hydraulic pressure of hot water or cold water changed suddenly, when perhaps the temperature of hot water changed suddenly, above two kinds of combination taps all must go to readjust water temperature by manual operation.The constant temperature regulating valve core that constant-temperature water faucet can carry by tap, the hydraulic pressure of autobalance cold water and hot water, to keep the stable of water-exit temperature, do not need to carry out manual tune fully in a short period of time.Constant-temperature water faucet appears at Europe the earliest, mainly contains at present two kinds of automatic temperature-control modes, adopts respectively different constant temperature valve cores: a kind of is paraffin thermostatic element spool.The working principle of paraffin the temperature module is that highly purified special paraffin is filled with in a tiny copper container, container lid a slice rubber vane.Due to the variation of water temperature, the paraffin volume in container also increases contracting thereupon, then drives by the vane of vessel port the mixed proportion that the spring pushing piston is regulated hot and cold water.What adopt at present this constant temperature valve core is mainly the producer in Europe.Another kind of constant temperature valve core adopts shape memory alloy spring.In the SMA constant temperature valve core, most important part is exactly shape memory alloy spring, and the shape memory alloy spring of being made by nitinol mixes the shape of the temperature change of rear warm water itself by induction, thereby pushing piston is regulated the mixed proportion of hot and cold water.SMA constant temperature valve core reaction velocity is exceedingly fast, and near the reaction 40 ℃ is extremely sensitive, can satisfy the needs that the user carries out stepless fine adjustment.Because constant temperature valve core is a kind of very accurate device, no matter adopt the inside processing of any form spool constant-temperature water faucet shell also to require very accurate, the tolerance of all inner processing dimensions should be limited in ± 0.1mm in, the tolerance of significant dimensions must be controlled at ± 0.05mm in.The recommendation water feeding pressure of general constant-temperature water faucet requires: 0.05MPA-0.59MPA, the water inlet water temperature requires: the entering water temp of hot water will keep preferably uninterruptedly providing the hot water of temperature more than 55 degree than more than high 7 degree of the temperature of setting.Constant-temperature water faucet is applicable to the shower facilities of family, hotel, bathhouse, and the environment that often changes of the hydraulic pressure such as barber shop.
The constant temperature valve core of water tap complex structure of domestic production is at present installed inconvenience.
