Abstract

The utility model relates to a water tank water inflow control valve for a toilet bowl, which is mainly composed of two ceramic chips, a floating ball, etc., wherein, the opening and the closing of a water inlet is controlled by the rotation of the two ceramic chips. The utility model overcomes the deficiency of the water tank which is easy to leak after long-term using.

Description

Rotary valve

The utility model relates to a rotary control valve door.

Continuous development along with society.Flush toilet is more and more universal.Up to ten million of the existing flush toilet in the whole nation, but also in increase at full speed.The water inlet of these toilet flushes at present all utilizes lever principle to come control switch.Shown in figure two (the inlet valve form of lever principle is a lot, is wherein a kind of here); Its working principle is to finish when water tank water intake, and ball float 4 come-ups down push away depression bar 2, block the water inlet of intake pipe 1, realize closing into water.But its shortcoming is to block the water inlet, depression bar 2 will overcome pressure of supply water, this power exists more greatly and always, ball float 4 levers 3 are stressed always when the water tank full water like this, therefore valve damages easily, also because intake pipe 1 and depression bar 2 generally are made of plastics easy deformation under water for a long time, damage, cause and leak.So existing toilet flush water leakage phenomenon is very serious---" ten have nine leakages ".

The utility model is the improvement to above valve, replaces leverage with rotary mechanism, replaces plastics to overcome above-mentioned defective with indeformable stupalith.

The purpose of this utility model is to realize like this; Two revolvable circular ceramics have three apertures on a slice, three moon grooves are arranged on another sheet relatively, can make current close and circulate when two porcelain are rotated in diverse location.

Major character of the present utility model is to replace Lever type mechanism with rotary mechanism.

Further describe below in conjunction with accompanying drawing:

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

As figure one, 1. intake pipe, 2. anchor ear, 3. screw, 4. connecting rod, 6. little axle, 7. fixing ceramics 8. rotates ceramics, 9. pad, 10. spring washer, 11. nuts.

Three small sircle holes are fixedly arranged on the ceramics 7, and to three moon grooves should be arranged, rotation ceramics 8 can be around little axle 6 rotations on the rotation ceramics 8.After the water in the water tank washes out, ball float 5 drops, driven rotary ceramics 8 rotates an angle, and at this moment aperture and moon groove are just in time aimed at, and water just flows to water tank; When the water level of water tank rose to certain altitude, ball float 5 was also along with rising, and driven rotary ceramics 8 rotates an angle, and at this moment aperture is covered by turn ceramics 8, and water inlet is switched off.The advantage of this valve is: because two ceramics surface of contact are very smooth, can regard no any air as between two faces that are adjacent to, therefore " suction " is very big relatively, be similar to the suffered atmospheric pressure in the two ceramics outside, this " suction " substantially exceeds the pressure of supply water of three suffered on the rotation ceramics 8 apertures to it.So connecting rod 4 when valve closing, ball float 5 is no longer stressed.It only plays the effect of rotating a lower porcelain slice 8.Therefore ball float 5 also can dwindle greatly than the ball float of Lever type valve.Also can not damage, so can increase the service life owing to ceramics is under water for a long time.

Sample produces a desired effect through on probation.

This valve also can be used on the water tank of tap water after amplifying.

Claims

A kind of rotary control valve door is made up of parts such as two ceramics, ball floats, and it is characterized by has aperture on the ceramics, corresponding moon groove is arranged on another ceramics, and two ceramics can rotate relatively.
