Abstract

The utility model relates to a water-saving valve for toilet cisterns, comprising a rubber ball valve matched with the port of a water output pipe, wherein, the rubber ball valve is fixedly connected with a valve rod which is sheathed in the guide hole of a guide bracket in the slide mode; the rubber ball valve is provided with a spring or a weight block which applies a down pressure on the rubber ball valve. Therefore, when a person releases the handle for operating the rubber ball valve, the rubber ball valve closes the port of the water output pipe instantly. The utility model can control the quantity of the water for flushing to save water according to the requirement. Simultaneously, the sealing performance of the rubber ball valve and the port of the water output pipe is enhanced to prevent the water from leaking. The utility model is suitable for toilet cisterns which use a float ball to control a water input valve and a rubber ball valve type flushing valve.

Description

Water-saving valve for toilet cistern

The utility model relates to a kind of flushing valve that is used in the toilet flush.

In the prior art, a kind of water box of water closet is arranged, controlling organization wherein is: thus control cistern water level by the keying of ball float control water intaking valve; Pass through the lever flushing valve to closet flushing by spanner.Its flushing valve is a rubber ball valve that the mouth of pipe with outlet pipe is complementary, and fixes a valve rod on the rubber ball valve, and the valve rod sliding sleeve is in the guide hole of guiding trestle.When needs during to closet flushing, pull spanner, poppet stem drives the rubber ball valve and rises by lever, and after the water in the water tank arrange, valve rod made the mouth of pipe of rubber ball valve aligning outlet pipe fall and seal under the guiding of guiding trestle; Simultaneously ball float falls and opens water intaking valve to water tank water intake, and ball float rises along with water inlet, and when cistern water level reaches predetermined water level, ball float is closed water intaking valve by lever.The rubber ball valve of this flushing valve is in light weight, when washing by water, can only wait until that water in the water tank has been arranged after, the rubber ball valve just can be closed the mouth of pipe of outlet pipe.Like this, each bath must rack up the water of putting in order water tank.Only need a small amount of bath to get final product for when urine, this flushing valve just causes a large amount of waste tap water, and rubber ball valve and the outlet pipe mouth of pipe be difficult for good seal, easily leaks.

The purpose of this utility model is to provide a kind of flushing valve that can discharge required discharging quantity of water and antileaking by the use human needs, to reach the using water wisely purpose.

For achieving the above object, the utility model adopts following technical proposals: this water saving flushing valve is the same with prior art to include the rubber ball valve that the mouth of pipe with outlet pipe is complementary, a fixedly connected valve rod on the rubber ball valve, the valve rod sliding sleeve is in the guide hole of guiding trestle.Be characterized in: on the rubber ball valve, settle a pressure piece.So just the rubber ball valve has been applied a downward pressure.Wash by water when the end user pulls spanner, hand one is decontroled spanner, and the rubber ball valve is just closed the mouth of pipe of outlet pipe immediately under the pressure piece effect, stop bath, reaches the using water wisely purpose.This pressure piece can be a spring, and the rubber ball valve is applied spring force; Also can be pouring weight, the rubber ball valve be exerted pressure with its gravity.Under the effect of pressure piece, also improve the sealing between the rubber ball valve and the outlet pipe mouth of pipe, prevent to leak.

Above-mentioned pressure piece can be such spring: this spring housing is on valve rod, and its lower end is seated at the upper surface of rubber ball valve, and its lower end is seated on the downside of guiding trestle.Like this, spring just applies spring force to the rubber ball valve.

But above-mentioned spring outside suit a sleeve, can protect spring first, moreover can be integral with the spring prepackage, is convenient to the installation of spring.This sleeve can be an outer sleeve by the lock dog inner sleeve that is slidingly connected, both ends of the spring is seated at the inner bottom surface of outer sleeve and inner sleeve respectively, the bottom surface of inner and outer sleeves has centre bore to join with the valve rod cunning, the openend of inner and outer sleeves has flange to collude upper and lower flange inner bottom surface in lock dog respectively, and lock dog is the two halves integrated structure.Like this, but spring and inner and outer sleeves and lock dog assembled in advance are integral.

Above-mentioned pressure piece can be annular pouring weight also, is enclosed within on the valve rod and is placed on the upper surface of rubber ball valve 7, and its gravity applies downward pressure to the rubber ball valve.Pressure piece also can be to be enclosed within valve rod to extend to annular pouring weight on the rubber ball valve insertion rod end, and annular pouring weight is placed in the rubber ball valve.Pressure piece also can be a pouring weight that directly is placed in the rubber ball valve body, just pouring weight is settled within it and the Pouring cast solid when Pouring casting rubber ball valve, prevents that pouring weight is subjected to water erosion when using.

The technical scheme of another same design of the utility model is: flushing valve includes the rubber ball valve that the mouth of pipe with outlet pipe is complementary equally, a fixedly connected valve rod on the rubber ball valve, and the valve rod sliding sleeve is in the guide hole of guiding trestle.Be characterized in: valve rod extends outside the tank lid, terminal fixedly connected handle.During bath, the end user pulls on handle and promptly opens flushing valve; Stop bath, the end user depresses handle and promptly closes flushing valve, promptly by manpower the rubber ball valve is exerted pressure, and realization rubber ball valve is closed the mouth of pipe of outlet pipe.This scheme simple in structure used also very convenient.

The utility model has following advantage compared with prior art: the utility model can not change the structure of original water tank, only through repacking easily simply again, just can be by end user's requirement operation control discharging quantity of water, using water wisely, simultaneously because of the rubber ball valve has been applied pressure, strengthen the sealing performance of rubber ball valve, prevent radiator leak, also reach the using water wisely purpose the outlet pipe mouth of pipe.
