Description

Anti-pollution airtight water tank

technical field

The utility model relates to a water tank for building domestic water, in particular to an airtight water tank which is suitable for a secondary water supply system and can prevent water pollution.

Background technique

At present, in the secondary water supply field of high-rise buildings, since the water supply department does not allow water pumps to draw water directly from the municipal water supply pipe network, most of the secondary water supply systems of buildings need to be equipped with low-level pools, and some buildings also need to be equipped with roof water tanks. Since the water surface of the pool or tank is open to the atmosphere, the residual chlorine content in the water decreases sharply and thus loses its inhibitory effect on bacterial growth. In addition, pollutants in the air are also easy to enter the water, thereby causing secondary pollution of the water body in the pool or water tank.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1～Fig. 4, a kind of anti-pollution airtight water tank, comprises water storage box body 1, float control water tank 15, water inlet pipe 10 and water outlet pipe 11, and described water storage box body 1 is provided with described water inlet pipe The water inlet 9 communicated with 10 and the water outlet 8 communicated with the outlet pipe 11, the float control water tank 15 is fixedly connected in parallel with the water storage tank 1, in the middle of the inner wall of the water storage tank 1 The bottom end of the floating cap-shaped rubber diaphragm 6 is connected through the fixed seal 7, the shape of the floating cap-shaped rubber diaphragm 6 is adapted to the inner cavity of the water storage tank 1, and the floating cap-shaped rubber diaphragm 6 The top surface of the shaped rubber diaphragm 6 and the upper end of the inner wall of the water storage box 1 form an overflow space 2, and the upper part of the inner wall of the water storage box 1 is provided with an overflow space that communicates with the overflow space 2 Orifice 13; the middle part of the top surface of the floating cap-shaped rubber diaphragm is provided with a duckbill rubber one-way valve 5, and the duckbill rubber one-way valve 5 is connected with a valve located in the overflow space 2 Duckbill outlet 4.

Water storage tank body 1 inboard lower half adopts fixed type, and inboard upper half adopts the floating cap shape rubber diaphragm that can rise and fall with the water surface. The fixed part at the inner lower end of the water storage tank and the floating part at the inner upper end of the water storage tank are connected by a fixed seal 7 at the inner middle of the water storage tank, so that the floating cap-shaped rubber diaphragm 6 is embedded in the water storage tank 1 Inside. The upper half of the inner side of the water storage tank adopts a floating cap-shaped rubber diaphragm 6 to prevent the volatilization of residual chlorine in the water and pollutants in the air from entering the water. The floating cap-shaped rubber diaphragm 6 is processed according to the shape of the pool. In this implementation The example is a five-sided cuboid. An overflow space 2 is formed between the top of the floating cap-shaped rubber diaphragm 6 and the inner side of the water storage tank 1 . A duckbill rubber check valve 5 is installed in the middle of the top surface of the floating cap-shaped rubber diaphragm 6, and water can only overflow from the inside of the water storage tank 1 through the duckbill rubber check valve 5, while the water storage Water and air outside the casing 1 cannot enter the water tank. The duckbill rubber one-way valve 5 is usually airtight. When an accident occurs in the water tank, the water level in the water storage tank 1 exceeds the maximum water level and exceeds the set pressure, and the water flows out from the duckbill rubber one-way valve 5 and flows concurrently. It enters the overflow space 2, passes through the overflow port 13, and is discharged by the overflow collecting pipe 14.

Both the water inlet 9 and the water outlet 8 are arranged at the lower end of the inner side of the water storage box 1 , and the fronts of the water inlet 9 and the water outlet 8 are provided with stainless steel grilles. It is used to prevent the floating cap-shaped rubber diaphragm 6 from being sucked by the water outlet 8 and the water inlet 9. Since the water inlet 9 of the water storage box 1 is arranged on the lower half of the water storage box 1, the water inflow forms a submerged outflow. In order to prevent backflow siphon from water stoppage at the water inlet end, a check valve 19 is added on the water inlet pipe 10 . A vent pipe 12 is connected to the bottom of the water storage tank 1 .

The float control water tank 15 is installed on the outside of the water storage tank 1, and the water inlet pipe 10 is linked with the float control water tank 15. When the water level in the water storage tank 1 rises, the floating cap-shaped rubber diaphragm 6 rises accordingly. At the same time, water in the water inlet pipe 10 enters the float control water tank 15 through the float control valve conduit 17, and the water level in the float control water tank 15 also rises, and the float 3 rises, and when it reaches a certain position, the outlet of the float control valve conduit 17 is closed. Water port 16, then closes the valve 18 on the water inlet pipe. When the water level in the water storage tank 1 dropped, the floating cap-shaped rubber diaphragm 6 also dropped thereupon, and the water level in the float control water tank 15 also dropped simultaneously, and the float 3 dropped, and the water outlet of the float control valve conduit 17 16 is opened, then the valve 18 on the water inlet pipe is opened, and the water inlet pipe 10 starts to enter water.

In order to ensure safety, in this embodiment, the inner fixed part of the water storage tank 1 is made of food-grade stainless steel and other materials, and the floating cap-shaped rubber diaphragm 6 is lined with food-grade materials.

Working principle of the utility model:

Please refer to Figures 5 to 6, when there is no water in the water storage tank 1, the floating cap-shaped rubber diaphragm 6 is attached to the fixed part at the inner lower end of the water storage tank 1, and when the water inlet pipe 10 has water passing through the water inlet 9 When entering the water storage tank 1, as the water level in the water storage tank 1 rises, the floating cap-shaped rubber diaphragm 6 rises accordingly, and at the same time, water in the water inlet pipe 10 enters the float ball through the float control valve conduit 17 Control water tank 15, the water level in the float control water tank 15 also rises, and float 3 rises, then closes the water outlet 16 of float control valve conduit 17 to a certain position, then closes the valve 18 on the water inlet pipe. When the water level in the water storage tank 1 dropped, the floating cap-shaped rubber diaphragm 6 also dropped thereupon, and simultaneously the water level in the float control water tank 15 also dropped, the float 3 dropped, and the outlet of the float control valve conduit 17 The water port 16 is opened, and then the valve 18 on the water inlet pipe is opened, and the water inlet pipe 10 starts to take in water.

When an accident occurs in the water tank, when the water level in the water storage tank 1 exceeds the maximum water level and exceeds the set pressure, the water flows out from the duckbill type water outlet 4 of the duckbill rubber check valve 5 and flows into the upper part of the inner side of the water tank. The overflow space 2 is drained away by the overflow collecting pipe 14 through the overflow port 13 .

Although the preferred embodiment of the utility model has been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative and not restrictive. Under the enlightenment of the utility model, those skilled in the art can also make many forms without departing from the purpose of the utility model and the protection scope of the claims, and these all belong to the protection scope of the utility model.
