Abstract

The utility model discloses a flushing device for the toilet which is operated by the pressure of a water source. The self pressure cistern is a sealing box which is connected to a tap water pipeline. A water inlet and a water outlet of the box are arranged at the lower part of the box. The water is injected into the box through the water pipe. The water level is gradually raised. The potential energy is accumulated by the compressed air on the upper part of the box. The powerful water flow is generated to cleanly wash the urinal when the water is discharged. The utility model has simple structure, low cost and water saving without maintenance. The flushing device for the toilet is suitable for various toilets.

Description

Self-pressure type water tank

The utility model relates to the flushing device of water-closet, particularly by the pressure-operated flushing device of water supply system.

At present, widely used flushing device is the float water tank in water-closet, and the float water tank is limit because of its structure, and large and small water supply volume is just all fixed, and the water yield of whenever putting once all is no less than 0.006 cubic metre.In addition, this cisten mechanism complexity, accessory rapid wear, maintenance is frequent, manufacturing cost is high, especially in recent years the plastic cistern of Sheng Chaning " defect is come forth in large number, and repaiies not well repeatly " especially, go out of use need not and change the quite a lot of directly flushing with tap water into, wasted water resource greatly.

The purpose of this utility model provide a kind of can using water wisely, simple in structure, cost is low, need not maintenance, the flushing device of long service life.

Self-pressure type water tank comprises water inlet pipe, inlet valve, casing, flowing water Valve, outlet pipe, and tank box is communicated with water inlet pipe and outlet pipe respectively, and all in the bottom of casing, whole box body seals to external world for the water inlet of casing itself and delivery port.

Daily treating the time spent, inlet valve is often opened, and flowing water Valve is normally closed, water storage in the casing.Before the water filling, casing does not lead to by the outlet pipe and the external world, and the pressure of its inner air accumulation is atmospheric pressure; When current are injected in the casing by water inlet pipe, the lower box water is hedged off from the outer world its internal gas, along with water level rises, air in the casing is squeezed and is reduced to casing top, when water level reach a certain height, air pressure in the casing upper cavity and source pressure relative equilibrium, water filling stops.At this moment, the water of putting aside in the case bears the pressure of upper air, and the water integral body of promptly storing in the case is all being born the pressure at water source, and more because of its amount of savings, capacity for work is stronger.When using flushing, open flowing water Valve, the water that the potential energy of the Compressed Gas savings in the casing upper cavity is stored the bottom pushes away apace, can reach the anxious strength of current, the effect that flushing is clean.

Self-pressure type water tank is simple in structure, and cost of manufacture is low, long service life, and whole none mobile machine parts need not maintenance in the use.Control flowing water Valve, regulating pondage arbitrarily.When source pressure during at 0.02MPa, water supply volume can be rinsed well for 0.0016 cubic metre; Large and small just balanced water, contrast float water tank can economize on water 60-70%, compares with directly flushing with tap water, when source pressure deficiency 0.06MPa, can economize on water more than 60%.

Further specify structure of the present utility model below in conjunction with drawings and embodiments.

Fig. 1 is the self-pressure type water tank connection diagram;

Fig. 2 is self-pressure type water tank casing embodiment 1 structural representation.

Fig. 3 is self-pressure type water tank casing embodiment 2 structural representations.

Self-pressure type water tank comprises water inlet pipe 1, inlet valve 2, casing 4, flowing water Valve 6, outlet pipe 7, and casing 4 is communicated with water inlet pipe 1 and outlet pipe 7 by joint 3 and joint 5 respectively.The water inlet of casing is all in the bottom of casing 4, and outlet pipe 7 is communicated with urinal 8.Whole box body 4 seals to external world.

It is cylindrical that embodiment casing 4 adopts plastics to make, and connected and composed by upper cover 10, barrel 11, low head 12 3 parts.Upper and lower end socket is threaded by union with inlet tube and outlet tube, and barrel and upper and lower end socket adopt welding.

Casing 4 tops connect water inlet pipe 1 in the embodiment 1, and outlet pipe 7 is connected in the bottom, and the core pipe 9 that has a upper end to be communicated with water inlet pipe in casing, the lower end delivery port of core pipe 9 are near bottom half, but casing is unsettled relatively.When inlet valve 2 is opened, when flowing water Valve 7 was closed, current injected casings by core pipe 9, and from bottom half water level raising gradually, with the air compression of the casing first half, up to pressure balance, water filling stops.

Casing 4 upper end closeds in the embodiment 2, water inlet pipe 1 and outlet pipe 7 are directly connected the bottom of casing 4 respectively; Current inject casing by water inlet pipe 1 during water filling, and the effect of its closed box bottom, Compressed Gas is with mode 1.

The utility model is simple in structure, easy for installation, occupy little space, and is fit to all kinds of washrooms and uses.
