Description

A kind of ceramic valve core water tap is used valve rod

Technical field

The utility model relates to a kind of valve rod, and particularly a kind of valve rod that is used on the ceramic valve core water tap is the improvement to the valve rod that uses on the present ceramic valve core water tap.

Background technique

Present ceramic valve core water tap occurs being not closed completely through regular meeting in use for some time; Perhaps after handle is moved the position when being in closed condition; Leakage phenomenon still takes place, though water leakage is very little, drop by drop; But according to the actual fact neither what minor matter, made water resources waste in vain.And tooth-like between handle with sleeve and the valve rod cooperate and often take place looseningly, and perhaps tooth is ground off.Analyze the deficiency below present ceramic tap exists from the internal structure of ceramic tap:

1, cooperates with the cylinder odontoid between handle with sleeve and the valve-rod body; Grown service time; Behind the inside and outside odontotripsis, it is big that the gap becomes, and makes after handle with sleeve has turned to the angle when making water tap be in buttoned-up status; Valve rod drive to rotate angle that ceramic plate rotated can not make rotate ceramic plate and fixedly the state position between the ceramic plate reach and make water tap be in the closing state position, thereby water leakage phenomenon takes place.

2, present water tap: valve rod and fixedly the distance between the ceramic plate be certain; After rotating ceramic plate and fixedly a certain amount of wearing and tearing being arranged between the ceramic plate, rotate ceramic plate and fixedly just have the slit between the ceramic plate because valve rod and fixedly the distance between the ceramic plate can not diminish; So rotate ceramic plate and fixedly the slit between the ceramic plate just can't eliminate; Thereby make that (this water leakage phenomenon is to be connected last time with washing machine when water tap in the time of the most tangible to water tap generation water leakage phenomenon, and certain pressure is arranged in the washing machine water pipe, makes that rotating ceramic valve core moves to valve rod; Thereby make and rotate ceramic valve core and the fixedly increase of the slit between the ceramic valve core; After faucet handle was closed, this slit still existed, and made water tap not close fully).

The model utility content

The utility model technical problem to be solved provides a kind of valve rod that is used on the ceramic valve core water tap; This valve rod can be eliminated automatically and rotate ceramic valve core and the fixing slit between the ceramic valve core, thus overcome because of rotate ceramic valve core and fixedly between the ceramic valve core wearing and tearing produce the generation that the slit causes water leakage phenomenon.Positive six terrace with edge shapes are made in the place that valve rod cooperates with handle with sleeve, and making cooperating between valve rod and the handle with sleeve is interference fit, prevent that it is loosening.

The utility model solves the technological scheme that its technical problem adopted: the ceramic valve core water tap of the utility model is used valve rod; Be by valve-rod body; Springs and handle with sleeve are formed, and it is characterized in that: handle with sleeve is in the upper end of valve-rod body, and springs is installed in the lower end of valve-rod body; When being assemblied on the water tap, the position of springs is between valve-rod body and rotation ceramic valve core.

The characteristic of said valve-rod body is: the position that the upper end of valve-rod body cooperates with handle with sleeve; Its shape is up-small and down-big positive six terrace with edges; There is pit the lower end of valve-rod body with the bi-side of rotating the ceramic valve core matching part, and the shape of pit is consistent with the shape of springs raising part.The characteristic of said springs is: there is convex portion (being used for fixing on valve-rod body) to the inside in the place that cooperates with valve-rod body; A side that contacts with ceramic valve core; Its shape is the spring bodies of two ends to the curved slabbing spring of a lateral bending of ceramic valve core; Be the main place that produces elastic force, springs is to make with the rigid material that can not get rusty.The characteristic of said handle with sleeve is: the identical endoporus of shape of positive six terrace with edges on its shape of the endoporus that cooperates with valve-rod body and the valve-rod body, the height of positive six terrace with edges is big on its aspect ratio valve-rod body.

The beneficial effect of the utility model is: the elastic force effect of springs can be eliminated automatically and rotate ceramic valve core and the fixing slit between the ceramic valve core; Thereby make water tap that water leakage phenomenon no longer take place; Reach water-saving purpose, prolonged the working life of water tap greatly.
