Automatic backwater flow dividing device with water sealing device

Technical Field

The utility model belongs to a nitrogen gas seal automatic return water diverging device on the nitrogen gas seal water tank among the ultrapure water system.

Background

Traditional backward flow waste water system comprises two automatic valve, and when nitrogen sealed water tank liquid level reached the high point, opened backward flow automatic valve, closed nitrogen sealed water tank automatic valve that intakes. When the liquid level of the nitrogen-sealed water tank reaches a low point, the water inlet valve of the nitrogen-sealed water tank is opened, and meanwhile, the automatic backflow valve must be closed. Meanwhile, a special water seal tank is arranged to ensure the nitrogen seal effect of the water tank.

Disclosure of Invention

The utility model aims to solve the technical problem that, this device provides a take water seal arrangement's automatic return water diverging device.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides a take water seal arrangement's automatic return water diverging device, has the preceding stage water tank of reserve water and can improve the purification equipment of water purity, and the preceding stage water tank switches on mutually with purification equipment, the back flow has been connect on the preceding stage water tank, and the back flow is connected in the water seal box, is equipped with back flow and blast pipe on the water seal box, back flow and blast pipe all are connected in the nitrogen seal water tank, are equipped with the nitrogen gas pipe of input nitrogen gas on the nitrogen seal water tank, be equipped with the delivery pipe on the purification equipment, delivery pipe and back flow switch on.

Preferably, in order to adjust the water inflow of the water inlet pipe, the return pipe is provided with a water inlet valve capable of controlling whether water enters or not.

Preferably, in order to adjust the content of the nitrogen in the nitrogen-sealed water tank, a micro-pressure difference adjusting valve for controlling the nitrogen to enter is arranged on the nitrogen pipe.

Compared with the prior art, the utility model discloses an useful part is: the device combines a backwater diversion system and the nitrogen-sealed water tank into a whole, and carries out water sealing on the nitrogen-sealed water tank simultaneously in the process of realizing automatic backwater diversion, so that the structure is simplified, and the functions are diversified.

Description of the drawings:

fig. 1 is a schematic structural view of an automatic backwater diversion device with a water seal device.

In the figure: 1. a preceding stage water tank; 2. a purification device; 3-1, a first return pipe; 3-2, a second return pipe 4 and a water seal tank; 5. an exhaust pipe; 6. a nitrogen-sealed water tank; 7. a nitrogen gas pipe; 8. a water supply pipe; 9. a water inlet valve; 10. and a micro-pressure difference regulating valve.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, an automatic backwater flow divider with a water seal device comprises a preceding water tank 1 for storing water and a purifying device 2 capable of improving water purity, wherein the preceding water tank 1 is communicated with the purifying device 2, and the automatic backwater flow divider is characterized in that: the pre-stage water tank 1 is connected with a first return pipe 3-1, the first return pipe 3-1 is connected to a water seal tank 4, a second return pipe 3-2 and an exhaust pipe 5 are installed on the water seal tank 4, the second return pipe 3-2 and the exhaust pipe 5 are both connected to a nitrogen sealed water tank 6, a nitrogen pipe 7 for inputting nitrogen is arranged on the nitrogen sealed water tank 6, a water supply pipe 8 is arranged on the purifying equipment 2, and the water supply pipe 8 is communicated with the second return pipe 3-2; in order to adjust the water inflow of the water inlet pipe conveniently, a water inlet valve 9 capable of controlling whether water enters or not is arranged on the second return pipe 3-2; in order to adjust the content of nitrogen in the nitrogen-sealed water tank, a micro-pressure difference adjusting valve 10 for controlling the nitrogen to enter is arranged on the nitrogen pipe 7.

Description of the functional principle: the device is an automatic backwater shunting device with a water seal, when the liquid level of a nitrogen-sealed water tank 6 reaches a high point, water is automatically shunted to a preceding water tank 1 backwater through a pipeline only by closing a water inlet valve 9 of the nitrogen-sealed water tank 6. The device combines a return water diversion system and the nitrogen-sealed water tank 6 into a whole, and water sealing is carried out on the nitrogen-sealed water tank 6 simultaneously in the process of realizing automatic return water diversion. When the liquid level of the nitrogen-sealed water tank 6 reaches a low point, the water inlet valve 9 of the nitrogen-sealed water tank 6 is opened, and the inlet water automatically flows to the nitrogen-sealed water tank 6. When the liquid level of the nitrogen-sealed water tank 6 reaches a high point, the water inlet valve 9 of the nitrogen-sealed water tank 6 is closed, the inlet water automatically flows to the nitrogen sealing device, and the inlet water flows back to the front-stage water tank 1 after being filled with the nitrogen sealing device. Therefore, the nitrogen-sealed water tank can be always in a nitrogen-sealed state completely isolated from air regardless of the water inlet state or the backflow state of the nitrogen-sealed water tank 6.

The existing device compares with the traditional device: the device shunts the water supply and the water return, only an automatic valve needs to be arranged on a pipeline, the water in a water supply pipe can be ensured to have a direction in any state, the safety of pure water preparation is ensured, only a water inlet valve of the nitrogen-sealed water tank needs to be closed, the water automatically shunts the water to the water return of a preceding-stage water tank through a pipeline, and simultaneously the nitrogen pressure in the nitrogen-sealed water tank can be ensured, and the nitrogen-sealed effect is ensured; traditional nitrogen-sealed water tank needs an solitary nitrogen-sealed water tank and return water diverging device, and return water diverging device comprises two automatic valves, under some trouble or special circumstances, can take place two valves and open and close discordance, or close simultaneously, causes the unable discharge of water supply, and the short-term or long-time suppressing pressure in the water supply pipe damages ultrapure water preparation equipment, causes great loss.

It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form, and any simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
