Abstract

The utility model discloses a sanitary water tap which is provided with two operating handles. In the process that a person uses the water tap, the upper handle can be operated to open the water tap by dirty hands, and the lower handle can be operated to close the water tap by cleaned hands; thus, the lower handle can not be contacted by the dirty hands, and the sanitation can be ensured; meanwhile, the utility model adopts a ceramic valve core, when the water tap is opened, water is exchanged between a movable valve core and a fixed valve core, and the water can not enter a control channel; a valve rod and a pressing nut do not need to be sealed, and a damageable sealing ring is saved; thus, the water tap of the utility model also has the advantages of corrosion resistance, good sealing effect and long service life of the whole body.

Description

Sanitary water tap

The utility model relates to a kind of sanitary water tap.

At present, the various sanitary water taps that use in the life, though internal structure respectively has characteristics, but majority is to adopt to allow the water that flows out directly wash handle to reach the health purpose, for this reason, the employing that has allows handle directly stretch out from water outlet, the employing that has allows handle be in the water outlet below, people use that purpose of sanitary water tap is a health in this, but everyone when washing one's hands dirty hand at first contact handle, easily booty is stayed on the handle, especially in public places, need a large amount of water to wash, the somebody also uses clean hand and comes to close water tap again behind the cleaning handle, makes troubles to the people.Also use a kind of ordinary faucet in the life, handle is contained in the top of water tap, adopt ceramic valve core, that ceramic valve core has is corrosion-resistant, the advantage of good sealing effect, long service life, but the water tap of the employing ceramic valve core that has is owing to the seal ring between valve rod and the gland nut weares and teares easily, cause between opening state lower valve rod and the gland nut and leak, this just causes the reduction of water tap bulk life time, and this mainly is that structural imperfection causes.

Goal of the invention of the present utility model is to provide a kind of advantages with above two kinds of water taps together, and bulk life time is longer, more the water tap of health.

Invention thinking of the present utility model is such, allow water tap that two handles are arranged, one of the upper end is the upper handle of ordinary faucet function, disconnected down one is the lower handle of sanitary water tap function, people use in the water tap process, dirty handling upper handle is opened, and the handling lower handle of cleaning is closed, and dirty like this hand no longer contacts lower handle, also health more just, simultaneously, water tap adopts ceramic valve core, and water only exchanges between movable valve plug and quiet spool during unlatching, water does not enter control channel, then need not seal between valve rod and the gland nut, save the seal ring of rapid wear, whole service life is longer.

To achieve the above object of the invention, sanitary water tap of the present utility model is by housing, upper handle, lower handle, valve rod, ceramic valve core, valve seat, gland nut, Sealing is formed, described ceramic valve core comprises a quiet spool and a movable valve plug, housing has intake tunnel, control channel and exhalant canal, this control channel and this exhalant canal are positioned on the straight line substantially, valve seat water inlet and valve seat osculum are arranged on the valve seat, this valve seat water inlet is communicated with intake tunnel with control channel, this valve seat osculum is communicated with control channel with exhalant canal, and the central axis that makes control channel and exhalant canal is in this valve seat osculum, from valve seat Sealing is housed successively upwards in the control channel, quiet spool, movable valve plug, have on this quiet spool with corresponding spool water inlet, valve seat water inlet and with the corresponding spool osculum of valve seat osculum, the transverse cross-sectional shape of this spool water inlet is the smaller part annular, this movable valve plug bottom has two grooves that shape is identical, the cross-section of the spool water inlet on the cross-section of this groove and the quiet spool is identical, the top seal of this movable valve plug upper groove, there is a mounting hole center of this movable valve plug, movable valve plug is contained on the valve rod by this mounting hole, gland nut is contained in the top of housing, valve rod is in the central axis place of control channel and exhalant canal, the upper end of valve rod is passed from the gland nut central part, upper handle is contained in the upper end of valve rod, the lower end of valve rod is passed from spool osculum and valve seat osculum, from exhalant canal, stretch out, lower handle is contained in the lower end of valve rod, tightening gland nut can be with valve rod, movable valve plug, quiet spool, Sealing and valve seat tightly force together, operation upper handle or lower handle can make movable valve plug rotate around the valve rod shaft axis, when wherein any groove of movable valve plug bottom is in spool water inlet opposite position is closed condition, when being in an end, the groove of movable valve plug bottom is overlapped on the spool water inlet, the other end is an opening state when being overlapped on the spool osculum, when the groove of movable valve plug bottom is 90 to be maximum opening state when spending in spool water inlet relative position.

For making operation sanitary water tap of the present utility model more laborsaving, can be at valve rod and gland nut locate to scribble lubricant oil movingly.

Sanitary water tap of the present utility model can be equipped with the spray guard of the middle guide hole of a band in the outlet port of described exhalant canal, described valve rod passes this centre guide hole.

Good effect of the present utility model is as follows: sanitary water tap of the present utility model has two operating grips, people use in the water tap process, dirty handling upper handle is opened, the handling lower handle of cleaning is closed, dirty like this hand no longer contacts lower handle, also health more just, simultaneously, the utility model has adopted ceramic valve core, water only exchanges between movable valve plug and quiet spool during unlatching, and water does not enter control channel, need not seal between valve rod and the gland nut, saved the seal ring of rapid wear, so that water tap of the present utility model also has is corrosion-resistant, good sealing effect, the advantage that whole service life is long.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
