Description
Technical field
The utility model belongs to valve technology field, and in particular to a kind of anti-water recovery apparatus.
Background technology
, it is necessary to use water valve to control entering for water body in the existing home appliance such as washing machine, dish-washing machine, intelligent water toilet pan
Go out and water flow size, due to hydraulic pressure in different regions there is no small difference, and with the presence of area hydraulic pressure not
Steady situation.And in no hydraulic pressure, hydraulic pressure is unstable or intake pressure drastically decline in the case of when, in home appliance water inlet end and
Water side will produce a negative pressure, because under suction function, the water inlet end of home appliance can produce siphonage so that family
Water backflow in electric equipment, the water body of backflow will pollute the water resource of water inlet end.And when water body pressure increases suddenly sometimes,
If control is improper, can also cause to overshoot effect so that home appliance damages.
In the prior art, asked although also having and taking different technical schemes to solve anti-overshoot and the backflow of anti-water-stop body etc.
Topic, but existing technical scheme is ineffective, structure is relatively complicated, and without universal applicability, and cost is high, general
Property it is poor, make trouble, product structure is complicated, assembly process is complicated, therefore in the prior art, it is impossible to can not still efficiently solve

The internal wall of trapping is provided with defining flange, and the anti-backwater pad, which has, to be driven by back-moving spring and cover and be located at institute
The anti-backed-up water level on defining flange end face is stated, and water is crossed by what internal current of trapping drove and separated with defining flange end face
Position.
When current enter from water inlet it is fashionable, the utility model compression reseting spring under water flow pressure cause anti-backwater pad with
Being separated with defining flange end face, water space was formed between anti-backwater pad and lower body so that anti-backwater pad was in water level,
So that current enter in upper sleeve body, and discharged from the delivery port of upper sleeve body.
When recirculation water enters in upper sleeve body from delivery port, anti-backwater pad is driven due to backflow water pressure and back-moving spring elastic force
Make and cover and be located on defining flange end face so that anti-backwater pad returns is covered on limit convex acies in anti-backed-up water level, anti-backwater pad
On face, trapped hence in so that current can not flow into vivo, so as to play anti-backwater effect.
In order to improve sealing effectiveness of the present utility model, preferably, matching somebody with somebody between the upper sleeve body and lower body for interference
Close.
Preferably, the upper sleeve body inside top is provided with the guide pillar towards the extension of lower body side, on the guide pillar
Guide channel is offered, the diversion rod being slidably matched with guide channel is provided with the anti-backwater pad.
Preferably, the back-moving spring is set on diversion rod, and one end is fixedly connected with the guide pillar, the other end
It is fixedly connected with the anti-backwater pad.
Preferably, being provided with first annular groove on the anti-backwater pad, first is provided with the first annular groove
Sealing ring.
Preferably, the lower body is provided with the second annular groove in the close position with upper sleeve body socket place, it is described
The second sealing ring is provided with second annular groove.
The first sealing ring and the second sealing ring in the utility model, which can use, has certain elastically-deformable material
It is made, plays a part of sealing.
Compared with prior art, the beneficial effects of the utility model are embodied in：
Have to be driven by back-moving spring by anti-backwater pad in the utility model and prevent to cover to be located on defining flange end face
Backed-up water level, and water level is crossed by what internal current of trapping drove and separated with defining flange end face, so as to realize anti-backwater effect.
The utility model application is wider, can apply to the water body control of plurality of devices, and the utility model can be with valve
It is used in combination, can also be separately installed, the phenomenon for the backflow of anti-water-stop body occurs.
Brief description of the drawings
