Description

Hydraulic pressure close type tap

The utility model relates to a kind of water tap (valve) on the running water pipe.

According to investigation, also do not find to have on the running water pipe this water tap at present to market.

At present, prior art is the rotary swivel handle, produce the power that moves downward with screw thread, the water of compaction tap valve is closed the water inlet, has following several respects problem therefrom: when people close water tap, all have the water tap of being afraid of to be not closed completely to produce the psychology of leaking, thereby excessive rotatable handle, cause damage, shortened the working life of valve rubber cushion, increase amount of maintenance seal rubber pad; Same rotatable handle tube squeezing valve can make valve rubber cushion unbalance stress produce damage and leaks, and this moment, people used bigger power rotatable handle, so that cause bigger injury such as fire hose captacula mouth stripped thread, and until changing water tap; Existing ceramic seal formula and beam barrel formula water tap all are to seal water by friction simultaneously, as the ceramic seal formula is to come switch water by friction sealed between two ceramic plates, the beam barrel formula is to come switch water by axle core and beam barrel friction sealed, all there are wearing and tearing thus, existence is to requirements in water quality, particularly existing high building all is a secondary water supply, the impurity that contains in the water, rust matter all can produce serious wearing and tearing to the water tap of above two kinds of on-off modes, the faucet valve core life-span is shortened greatly, produce water clock; Existing in addition water tap can not be adjusted automatically to adapt to variation in water pressure, when people close water tap, closed water tap at that time tight and do not leak, but people leave the back or to night when hydraulic pressure increases, water tap can drop down water again automatically, causes water resource waste.Concluding thus gets up is: existing water tap all exists outer power and spool friction to come switch water, and existence is worn and torn and made water tap make the lost of life thus, causes water clock.Amount of maintenance is big when using simultaneously, is subjected to the influence of water quality, open and close water tap effort, and faucet valve core can not be regulated the variation of hydraulic pressure automatically and produce water clock water.

The purpose of the present utility model is exactly in order to solve the above problems: make the more convenient labour-saving open and close of water tap energy; Can not cause wearing and tearing when making the water tap open and close, thereby prolong its working life spool; Can adjust the variation when adapting to hydraulic pressure and increasing after water tap is closed automatically, thereby reach watertight; And a day solution makes water tap not be subjected to the problems such as influence of water quality.

Design concept of the present utility model is: the hole, garden in the valve rod 13 1 ends importing lower seal valve rubber cushion 19, import again in the handle 8, and then lower seal valve rubber cushion 19 is fixedly mounted in the water tap water storage 2, when closing water tap, rotatable handle 8, handle 8 drives valve rod 13 and moves upward, make valve rod 13 and lower seal valve rubber cushion 19 seal valve rod into and out of tank 3, the hydraulic pressure foot makes valve rod 13 press lower seal valve rubber cushion 19 in the water storage 2 at this moment, and the closing valve connecting rod is into and out of tank 3.After closing water tap, this moment, there was a gap at handle and valve rod top chalaza 9 places, be to regulate variation in water pressure, when hydraulic pressure becomes big, valve rod 13 pressures are big more, thereby valve rod 13 is moved upward automatically, seal valve rod more closely into and out of tank 3, thereby reach automatic adaptation variation in water pressure and do not produce water clock water, it is stressed even that hydraulic pressure makes lower seal valve rubber cushion 19 simultaneously, avoids excessive rotatable handle to valve rubber cushion and other components damage.When fetching boiling water tap, handle 8 moves downward, and handle and valve rod top chalaza 9 compressing valve rods 13 move downward, and valve rod 13 is opened valve rod into and out of tank 3, and current flow to tube core osculum 15 from 3, flow out from going out sump 16 again.Find out thus, 13 of valve rods back and forth movement in the form of piston, to lower seal valve rubber cushion 19 frictional force without spin, increase thereby the faucet valve core longevity is closed greatly.Simultaneously since hydraulic pressure to valve rod 13 usefulness, make when turning off the tap very light, thereby realize goal of the invention.
