Description
Technical field
The utility model is related to a kind of anti-syphon structures of cistern free pressure flush toilet.
Background technology
Toilet seat (closestool) generally comprises toilet seat and water tank two parts, and water-inflow and drain valve is equipped in water tank to rinse
Closestool is generally provided with air entry in order to avoid the aqueous reflux in water tank is to water system polluted drinking water at the top of inlet valve
The anti-siphon mechanism of formula has a siphon critical line CL label, standard that the working water bit line in water tank is required to want under air entry
Apart from this CL lines 25MM or more.This design is only applicable to traditional gravity cistern, is not particularly suited for pressure flush water tank.
So-called pressure flush water tank does not imply that pressure flush valve, and refers to that there are one the closed of special pressure store water
Water tank container, need bath when can the unlatching of flushing valve effect under pressure release, then can with automatic feeding water restore water
Pressure, this pressure flush cistern system can not use conventional CL to mark the critical anti-siphon of label wire type, because inside pressure water tank
Water check valve sealing be destroyed in the case of can directly flow back into water system to polluted drinking water source.
Some existing pressure water tank flushing systems are substantially high flush tank design on the market at present, i.e., pressure water tank is whole
It is arranged and is placed higher than the highest spillwag chute of toilet seat, they mostly simply combine anti-return using individual event valve and vacuum breaker
With anti-siphon, such design can not actually prevent the pressure water inside pressure water tank from flowing back into water system, but entire
Pressure water tank is because of the sewage backflow that higher than toilet seat, can accomplish to prevent inside toilet seat when blocking to pressure water
Case, therefore mentally saying from anti-siphon, it is not sewage that the water inside pressure water tank, which can consider, and such anti-siphon measure is
Safety.
But it is less than this toilet device of toilet seat spillwag chute for pressure water tank, above-mentioned anti-siphon measure is with regard to invalid
.Because when pressure water tank is less than toilet seat spillwag chute, pressure water tank can not prevent the sewage that toilet seat is generated when blocking
Pressure water tank is flowed back into, because in this case, the water inside pressure water tank should be treated as sewage to design anti-siphon, simply
Come anti-return and anti-siphon it is invalid using check valve and vacuum breaker
Invention content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of cistern free pressure flush toilets

Water outlet connection there is check valve, the water outlet of the check valve and the pressure water tank of toilet to be connected；Positioned at movable valve plug
Group front end side is provided with the vacuum breaker being connected with sluice；Being provided in ontology water intake end prevents the unidirectional of water reflux
Valve.
In the utility model embodiment, the movable valve plug group includes the mandrel being located within the body, one end of the mandrel
It is provided with connection ring, a spring is provided between one end and ontology of the connection ring, the other end setting of the connection ring is useful
In the waterstop pad for opening and closing sluice water flowing.
In the utility model embodiment, the ontology is located at the inlet channel water inlet other end and is provided with an end cap, the end
Lid with connect interannular and be provided with spring, the connection ring periphery is arranged with sealing ring, the waterstop pad through lock-screw with connect
Ring is connected.
In the utility model embodiment, the check valve water outlet connection has one to cross water pipe, the water outlet for crossing water pipe
It is connected with pressure water tank, crosses between water section and pressure water tank and be provided with split ring and locking nut.
In the utility model embodiment, an another check valve for preventing water from flowing back is arranged in the water inlet end of the ontology.
A kind of anti-syphon structure of cistern free pressure flush toilet of the utility model, has the advantages that：
1, the water inlet of anti-syphon structure is provided with check valve prevents water from flowing back.
2, prevent siphon from generating in the water inlet side of anti-syphon structure setting vacuum breaker.
3, in the water outlet of anti-syphon structure, setting check valve can normally prevent the sewage backflow in pressure water tank.
4, it is internally provided with movable valve plug group in anti-syphon structure, even if check valve sealing is destroyed, moves spool
Group remains able to close water route, thoroughly prevents sewage backflow to water system.
5, the anti-syphon structure does not have any external overflow port, does not have water and drains to outside closestool, safer.
