Abstract
The utility model relates to an anti-back-leakage water tank, which comprises a tank body, wherein a water inlet communicated with a water feeding pipe is arranged at the bottom of the tank body and in a water groove; the water groove is arranged along the inner wall of the tank body; a water outlet is arranged at the upper edge of the wall of the water groove; a cover is arranged on the water groove; and a check mechanism is arranged between the cover and the water inlet. Since the water groove is arranged in the tank body, when an electromagnetic valve is opened, running water is fed through the water feeding pipe, flows in the water groove through the water inlet via the check mechanism, and water in the water groove flows into the tank body through the water outlet. On the contrary, when the electromagnetic valve is closed, residual water in the tank body can not flow back into the water feeding pipe due to the check mechanism, thereby avoiding reversal back flow effectively.
Description
Technical field
The utility model relates to a kind of water tank, especially a kind ofly prevents back waste tank.
Background technology
The product of paddling often uses the shutoff of electromagnetic water inlet valve control tap water and opens, and electromagnetic water inlet valve is opened, and intakes in water tank; Otherwise electromagnetic water inlet valve disconnects, and stops to intake in water tank.Yet electromagnetic water inlet valve does not often have reverse turn-off function, if there is water very easily to cause the water in the water tank oppositely to flow in the tap water pipe in the water tank.
The utility model content
The purpose of this utility model is to provide a kind of waste tank of preventing back that can prevent reverse counterflow.
For achieving the above object, the utility model has adopted following technical scheme: a kind ofly prevent back waste tank, comprise casing, the water inlet that is communicated with water inlet pipe is offered in the bottom of casing, water inlet is positioned at tank, and tank arranges that along the inwall of casing the upper edge of tank cell wall sets out the mouth of a river, lid is installed on the tank, between lid and the water inlet non-return mechanism is set.
As shown from the above technical solution, the utility model is provided with tank in water tank, and when electromagnetic valve was opened, tap water was intake by water inlet pipe, and water inlet is intake in tank through non-return mechanism, and the water in the tank flows in the casing by delivery port; Otherwise when closed electromagnetic valve, because the existence of non-return mechanism, the water in the casing can't be back in the water inlet pipe, can effectively prevent reverse counterflow.
Description of drawings
Fig. 1 is the structural representation of lid in the utility model;
Fig. 2,3 is respectively the structural representation before the installation lid, behind the installation lid;
Fig. 4 is a sectional view of the present utility model.
The specific embodiment
A kind ofly prevent back waste tank, comprise casing 1, the water inlet 2 that is communicated with water inlet pipe 3 is offered in the bottom of casing 1, water inlet 2 is positioned at tank 4, tank 4 arranges that along the inwall of casing 1 upper edge of tank 4 cell walls sets out the mouth of a river 5, and lid 6 is installed on the tank 4, between lid 6 and the water inlet 2 non-return mechanism is set, shown in Fig. 1,2,4.
Shown in Fig. 1,2,3,4, described non-return mechanism comprises rubber stopper 7, and the lower end of rubber stopper 7 is positioned at water inlet 2, and the lower end of the upper end of rubber stopper 7 and spring 8 is connected, and the upper end of spring 8 is fixed on the lid 6.Described lid 6 comprises cover plate 9, offer at least two through holes 10 on the cover plate 9, offer at least two installing holes 14 with the corresponding position of through hole 10 on the tank 4, tap bolt is fixed on cover plate 9 on the tank 4, cover plate 9 belows are provided with the cylindrical shell 11 of hollow, being shaped as of cylindrical shell 11 cross sections is rectangular poroid, is symmetrical arranged in the cylindrical shell 11 to be used for spring 8 is carried out spacing spacing block set 12, offers the opening 13 that supplies water and flow out on the cylindrical shell 11.The upper end of described spring 8 is installed on the lower face of cover plate 9, and spring 8 is positioned at cylindrical shell 11.
When work, when electromagnetic valve is opened, water inlet in the water inlet pipe 3, because the effect of tap water hydraulic, the rubber stopper 7 that tap water will be positioned at water inlet 2 backs down, and rubber stopper 7 moves upward and compresses spring 8, and tap water flows in the cylindrical shell 11 of lids 6 by water inlet 2, tap water flows in the tank 4 through the opening 13 of cylindrical shell 11 then, flows in the casing 1 through the delivery port on the tank 45 at last.Otherwise, when electromagnetic valve turn-offs, there is not water to flow in the water inlet pipe 3, because the elastic force of spring 8, spring 8 drives rubber stopper 7 and moves downward, rubber stopper 7 returns are blocked water inlet 2, thereby the water in the casing 1 can't be back in the water inlet pipe 3.
