Description
The utility model relates to Flushing cistern for closet, especially refers to a kind of pollution-free vapour-pressure type Flushing cistern for closet.
Existing Flushing cistern for closet all is a kind of casing of hollow seal, has only one to take over the mouth of a river on it, draining is supplied water and is all taken over the mouthpiece load by this, the feed pipe of tap water is entered by lower box through this segment pipe, is stored in the stagnant water in the case, also will pass through this segment pipe.Therefore produced under following situation and the tap water water source has been polluted the harm of the edible sanitary of water sources of influence.For example: 1, under the situation of water supply non-return line malfunctioning (or the non-return line is not installed) and tap water hydraulic step-down, be stored in stagnant water in the case and will flow back in the water supply pipe and pollute; 2, work as tap water cut-off, the water storage in the case discharges again and is over, and when not closing draining valve again simultaneously, the foul smell of water closet pan and bacterium will enter in the water supply pipe, and the water source is polluted.Generally speaking, casing itself does not have the device that prevents pollution of waterhead is set, and can not guarantee during work can not pollute the water source.
The purpose of this utility model is in order to overcome the above-mentioned shortcoming that existing water tank exists, to design and provide a kind of pollution-free vapour-pressure type Flushing cistern for closet.
The purpose of this utility model is achieved in that pollution-free vapour-pressure type Flushing cistern for closet, comprises casing, feed pipe, gutter and the valve of hollow seal, and it is characterized in that: casing is except that being provided with gutter, and other is provided with feed pipe, and water intaking valve is arranged on the feed pipe; This feed pipe top extends in the casing, and is provided with trap, the height of water storage face when its delivery port is higher than operate as normal.
Above-mentioned design will be set up separately for, drainage pipe, can prevent that aqueous reflux is gone into running water pipe in the casing, prevent that again foul smell from entering the possibility of running water pipe, obtain the effect that prevents to pollute tap water fully.
Be described further again below by drawings and Examples.
Fig. 1 is the utility model embodiment organigram.
As shown in the figure: casing has gutter 12 3 times, and other is provided with feed pipe 13, and water intaking valve 6, flap valve 7 are arranged on the feed pipe 13; Mat union nut 5 feed pipes 13 extend in the casing 3, and are provided with trap 4, and trap 4 can adopt the P type to become S type trap, and the height of water storage face 14 when its delivery port 2 is higher than operate as normal can prevent that contaminant water, foul smell from entering tap water.Plug 1 is arranged on the casing 3, and gutter 12 mat union nuts 8 are installed in casing 3 times, and are provided with movable joint 9 draining valves 10, and this draining valve 10 can adopt ball valve or time-delay flushing valve.Casing 3 configuration designs can be oval cartridge type, and promptly cross section is oval, can be near wall and take the purpose of water closet pan 11 superjacent air spaces less to reach, kept sealed construction, leak resistance is good, no moving parts in the casing, the tired brain developing result of removing maintenance from is good, both artistic and practical.
