Abstract

The utility model relates to a water-saving leakage-preventing discharge valve for a toilet cistern, which comprises a controlling device, a sealing device and a positioning device. The utility model adopts centralized positioning, double guide and vertical opening and closing in order to ensure accuracy that the sealing device returns and drops to a water outlet of a valve seat. A valve core is arranged on the sealing surface of sealing device, and the sealing surface is provided with a water sealing corner which is used for stopping leakage caused by the deformation of the sealing device. The traditional structure with flexible connection is replaced with hard connection between a handle (switch) and the valve core, so the opening and closing functions of the handle are realized; the user can control freely the water discharge quantity of the cistern according to requirements. The utility model is the current discharge valve for the toilet cistern, which is the ideal product which replaces the older generation.

Description

Tank for excrement pan water saving leakproof draining valve

The utility model relates to sanitary fittings, is a kind of tank for excrement pan water saving leakproof draining valve.

The tank for excrement pan draining valve is of a great variety at present, because structure is unreasonable, causes performance and effect not very good.Subject matter is draining valve because of producing, the distortion that brings being installed, and it can not be sealed fully and seepage occurs; The mechanism for opening/closing of draining valve all uses various ropes to be flexible coupling, and not only weares and teares easily, wears out, and can only just can automatically reset and close, quick closedown at any time artificially after arrange whole box water.

It is a kind of simple in structure that the purpose of this utility model is to provide, not easy to leak; Centralized positioning, the vertical keying; Highly versatile, the tank for excrement pan water saving leakproof draining valve that water-saving result is good.

The utility model is achieved in that tank for excrement pan water saving leakproof draining valve comprises control, sealing and positioner.Control device is fixed on handgrip (being switch) on the water tank or on the tank lid by handle bracket, cap, connects connecting rod, universally buckles, the valve gap bar forms.Sealing device is by spool, and the sealing mat on the spool, fastening nut are formed.Positioner is made up of with the guide housing that is installed on the valve seat the valve seat that clamp nut, sealing taper liner are fixed on water tank bottom.

Accompanying drawing is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:

Tank for excrement pan water saving leakproof draining valve comprises control, sealing and positioner.The handgrip of forming by control device 1 or 1 ', connecting rod 2 or 2 ', universally buckle 3, all be hard the connection between valve gap bar 5, part and the part, not only can directly open water tank drain valve fast, also direct quick closedown water tank drain valve, and all be under the dual guiding of guide housing 4, vertically to open and close.

Greater than the contact area of sealing mat 11 with spool 6, and the sealing surface of spool 6 and sealing mat 11 has water shutoff angle 10 to sealing mat 11 at the outfall area of valve seat 8.The water shutoff angle can remedy the seepage that the distortion because of sealing device brings, and the stamping press that is produced in the time of also making valve closing obtains buffering.

The floor space of spool 6 is greater than the twice of the outfall area of valve seat 8, and the bottom surface of spool 6 is gradient, can increase the buoyancy of valve closing during moment, plays throttling noise elimination effect.

Guide housing 4 is vertically mounted in the periphery and location notch hole of valve seat 8, and the column of guide housing 4 is for the ball float outside guiding of valve gap bar 5 bottoms, and the trough of belt mesopore of guide housing 4 is the rod tube external diameter guiding at valve gap bar 5 middle parts.

During installation, the sealing taper liner 12 of the valve seat 8 of draining valve together with the bottom is placed in the water tank macropore, put another sealing taper liner 12 more outside, the clamp nut 9 of screwing on, and tighten in right amount with wrench ... then, the sealing device that assembles, the top rod tube of valve gap bar 5 is from the mesopore string mistake of guide housing 4, the guide upright post of guide housing 4 inserted in the location notch hole of mounted valve seat 8 to lock again.Connecting rod 2 or 2 ' microcephaly go here and there into kink and buckle in 3 in the universal of valve gap bar 5 tops, and major part is installed on handgrip 1 or 1 ', and uses handle bracket, and cap is fastening.

During use,, collude by connecting rod 2 or 2 ' and universally to buckle 3 as long as plate is started 1 or spurred handgrip 1 ' gently, pull-up valve gap bar 5 and sealing device, water just pours urinal from the outfall of valve seat 8.When the gravity on the sealing device during greater than the buoyancy on the valve gap bar 5, valve gap bar 5 continues automatically to fall after rise under the dual guiding of guide housing 4, until sealing device the outfall on the valve seat 8 is closed.It is quantitative draining.Also can be according to actual needs, by the time you think that water has dashed when enough, plate is started 1 or is pressed handgrip 1 ' in the opposite direction, at this moment under the effect of external force, make gravity on the sealing device greater than the buoyancy on the valve gap bar 5, sealing device is descended rapidly, the outfall on the valve seat 8 is closed.Water tank begins water inlet again and constantly repeats above-mentioned circulation.

The utlity model has following advantage:

1, centralized positioning, dual guiding, the vertical keying fallen after rise extremely to guarantee sealing device The accuracy of valve seat discharge outlet.

2, the sealing surface of spool and seal has the water shutoff angle, the seepage of bringing with the distortion of stopping because of sealing device.

3, the hard connection between handgrip (switch) and the spool, broken traditional soft binding structure, made handgrip really accomplish the "on" and "off" effect, the user can control the displacement of water tank as required arbitrarily.

Claims
