Abstract
The utility model relates to a water-saving tap. The utility model is characterized in that a valve rod is arranged in an installing channel of the valve rod, and a water inlet channel is positioned at the same straight line as the installing channel of the valve rod. The length of the valve rod can cause a valve core to stretch in the water inlet channel. The water-saving tap also comprises a position controlling device of the valve core which can cause the valve core to disengage from the valve seat when the valve rod is downwards pressed, and can cause the valve core to automatically block the valve seat when the press is loosened. The valve rod is downwards pressed when water is used, water is automatically cut off after a hand loosens, water waste which is caused because the water tap is not closed or is not tightly closed is effectively prevented, and the effect of water saving is achieved. The water-saving tap is particularly suitable for public occasions which are not taken care of by special people, and is also suitable for families.
Description
The utility model relates to a kind of control valve unit, particularly relates to a kind of water conserving tap.
At present, the set water tap in public arena comprises the housing that is spun and formed by upper shell and lower shell body, handle, have externally threaded valve rod, assembly such as spool and valve seat, described housing has the intake tunnel that is interconnected, exhalant canal and valve rod are installed passage, intake tunnel and valve rod are installed passage not on a center line, handle and spool are loaded on the two ends of valve rod respectively, put on the round platform in the housing on the valve rod and be contained in the black box of upper shell upper end, upper shell is positioned on the lower cavity peripheral wall of round platform below and is shaped on the internal thread that can be complementary with the outside thread on the valve rod, the bottom of upper shell and the bottom of valve rod spin, described black box is made up of snap-in capping and stuffing box packing, stuffing box packing places on the interior round platform end face of upper shell, capping spins with the upper shell upper end and the lower end closely contacts with stuffing box packing, and valve rod is installed passage is realized the wall and the valve rod of this passage by capping and stuffing box packing sealing.Handle is positioned at the top of housing, by handle with sleeve valve rod is rotated on upper shell, and the rotation of valve rod on upper shell can realize the lifting of the relative valve seat of spool, thereby realizes opening or closing of water tap.This water tap has been widely used in family and various public place.But have following shortcoming when it is used in the public place: owing to adopt spiral lift to open and close, therefore Chang Yin is not closed completely and causes water leakage phenomenon after use, even some people is after using up water, because of the hand of fearing to make dirty after cleaning, and deliberately do not close water tap, caused the waste of water.
The purpose of this utility model is to provide a kind of water conserving tap that uses the back automatic shutoff.
The purpose of this utility model is by providing a kind of water tap with following structure to realize, this water tap comprises: the housing that is spun and formed by upper shell and lower shell body, button, have externally threaded valve rod, spool and valve seat, described housing has the intake tunnel that is interconnected, exhalant canal and valve rod are installed passage, button and spool are loaded on the two ends of valve rod respectively, put on the round platform in the housing on the valve rod and be contained in the black box of upper shell upper end and place valve rod that passage is installed, intake tunnel and valve rod are installed passage and are positioned at always on the line, the length of valve rod can put in the intake tunnel spool, and this water tap makes spool break away from valve seat when also comprising under one by valve rod, unclamp the valve element position control gear that makes spool block valve seat automatically when pushing.
Described valve element position control gear is made of the nut that is positioned at upper shell, spring, and nut and valve rod spin, and spring contacts with the round platform end face with nut respectively at two ends up and down with valve rod socket and its.
As further improvement of the utility model, there is a seal arrangement below of the inherent valve element position control gear of upper shell, this device is made up of the upper cap nut, Upper gasket, circular leather cup, lower levelling plate, the lower nut that are contained in successively on the valve rod, upper cap nut, lower nut and valve rod spin, Upper gasket, lower levelling plate and valve rod socket, the cavity peripheral wall that is in the round platform below in leather cup inner ring and valve rod, leather cup outer ring and the upper shell is sealed and matched.After adopting this structure, except that can preventing that the valve rod upper end from leaking, spring is not contacted with water, be difficult for getting rusty, thereby effectively prolong the working life of water tap.
Described black box is made up of external capping and seal ring.
The utility model water conserving tap is compared with the water tap of prior art has following advantage: because this water tap makes spool break away from valve seat, unclamp the valve element position control gear that makes spool block valve seat automatically when pushing when having under one by valve rod, therefore, pressing valve rod downwards during water gets final product, but automatic shutoff after loosing one's grip, effectively prevent the water waste that water tap is not closed or is not closed completely and causes, reached water-saving result.
Below in conjunction with accompanying drawing mode of execution of the present utility model is described in further detail.
Accompanying drawing is the structural representation of the utility model water conserving tap.
By accompanying drawing as can be known, has the intake tunnel 10 that is interconnected by upper shell 4 and lower shell body 8 housing that forms that spins, exhalant canal 14, valve rod is installed passage 6 and valve seat 9, valve seat 9 is in the lower shell body 8, the round platform 5 that one center drilling is arranged in the upper shell 4, intake tunnel 10 is installed passage 6 with valve rod and is positioned on the straight line, and lay respectively at the below and the top of valve seat 9, put on the round platform 5 in the housing 4 on the valve rod 7 and be contained in the black box of upper shell 4 upper ends and place valve rod that passage 6 is installed, black box is made up of external capping 2 and seal ring 3, button 1 spinning is in valve rod 7 outer ends, spool 11 is by nut 12, nut 13 is contained in valve rod 7 the inners, it is longer to work valve rod 7 length of opening the water tap effect, spool 11 can be put in the intake tunnel 10, there is a valve element position control gear upper shell 4 inherent round platforms 5 tops, this device is by nut 21, spring 20 constitutes, nut 21 spins with valve rod 7 tops, the spring 20 that plays pressed spool 11 effects contacts with round platform 5 end faces with nut 21 respectively at two ends up and down with valve rod 7 top sockets and its, elastic force by turn nut 21 Regulation springs 20, the tightness degree that may command spool 11 matches with valve seat 9, the below of upper shell 4 inherent valve element position control gear also has a seal arrangement, this device is by the upper cap nut 19 that is contained in successively on the valve rod 7, Upper gasket 18, circular leather cup 17, lower levelling plate 16, lower nut 15 is formed, upper cap nut 19, lower nut 15 spins with valve rod 7, Upper gasket 18, lower levelling plate 16 and valve rod 7 sockets, leather cup 17 inner rings and valve rod 7, the cavity peripheral wall that is in round platform 5 belows in leather cup 17 outer rings and the upper shell 4 is sealed and matched, the correct position place of described seal arrangement between valve rod 7 two end part.
It shown in the accompanying drawing closed condition of water tap.With the downward pressing button 1 of hand, promote valve rod 7 and move down, spool 11 moves down thereupon and breaks away from valve seat 9, opens tap, and water flows out through intake tunnel 10, valve seat 9, valve rod installation passage 6, exhalant canal 14; In case hand leaves button 1, button 1 suffered downward longitudinal thrust will disappear, and spool 11 is blocked valve seat 9, cutout cock automatically moving on immediately under the effect of spring force.
