Description

Economize water valve

Technical field

The utility model relates to province's water valve, relates in particular to a kind of province's water valve structure-improved that buffering is closed water function that has.

Background technique

The general now conduit control valve of traditional type on the market all is installed in the water faucet top, though it has advantage of simple structure, but after people finish the washing action, must just be operated the control valve that is positioned at water faucet top with portable, this closes the waste that can cause water resources when hydrodynamic(al) is done.

For solving the problem of waste water resource, development has a kind of infrared induction water valve on the market, when people wash action, hand is placed in induction region, by ultrared induction water valve is opened, and after finishing washing action hand being removed, water valve just can cut out automatically, and then is reached the effect of water-saving, but, because what infrared rays can be responded to is a location, people often repeatedly attempt just being able to hand is placed on suitable sensed position via need, have therefore caused the inconvenience of using.

So development has a kind of province water valve at present, as shown in Figure 6, this province's water valve is to be provided with a control valve group (70) in a receiver (60), directly be installed in the waterexit end of water pipe, and be to control water outlet and Guan Shui with the mode of operation of pushing control valve group (70), people can operate according to demand, with water-saving and the convenient advantage of using, yet, the moment of Guan Shui, current in the water pipe still have the situation that flows towards the waterexit end, and the kinetic energy that water produced that flows can change elastic energy into, and then produce a series of positive/negative pressure ripple and concussion back and forth in water pipe, be obstructed because of friction up to energy and stop, the situation that this phenomenon will cause harsh noise and water pipe to damage, and because utilization hydraulic pressure start relation, when hydraulic pressure is big, when control valve group (70) is pushed in operation, often need apply bigger power opposing hydraulic pressure, and cause operational feel comparatively to have some setbacks, historical facts or anecdotes has necessity of improvement.
