Technical field
The utility model relates to technical field of valve manufacturing, especially a kind of self-locking water tap for current open and close and flow control.
Background technique
Water tap on the market is of a great variety, and induction type, hand push type, foot-operated, rotary etc. are arranged, and some water tap only is applicable to more specific places, and some then involves great expense, and is not suitable for family to use; Now family uses mostly is the manual rotary water tap, this low price, and easy to use, popularity rate is higher.But traditional manual rotary water tap does not possess the auto-lock function of cutting off the water, and the shortcoming of this water tap is: after cutting off the water, close water tap as if forgetting, often cause when coming water again, water tap can not be closed automatically, causes the waste of water resources.Therefore, the cut off the water appearance of self-locking water tap becomes a kind of inexorable trend.
The major function of self-locking water tap is to forget that closing water tap also can realize closing automatically the back people that cut off the water even cut off the water, and is unlikely to occur the situation of flood and waste water when coming water again, effectively using water wisely.Existing self-locking water tap on the market, its project organization principle mainly comprise external force such as the magnetic force, gravity of elastic force by elastic element, magnetic element, consider simultaneously to supply water and the variation in water pressure when cutting off the water, and realize cutting off the water self-locking by linking mechanism; As:
