Referring to fig. 1 to 5, there is schematically shown a depressurized water tank and a water supply and drain assembly thereof according to the present utility model, including a water tank 1, a water supply assembly 2 fixedly connected to the top of the water tank 1, and a first drain pipe 32, a second drain pipe 4, and a sub-overflow pipe 31 respectively fixedly connected to the bottom of the water tank 1, which are introduced into the interior of the water tank 1.

The tank 1 is typically placed in a preparation room of a laboratory bulkhead, with its height set at most 3m from the ground, using a gravity water supply system. The range is set in consideration of actual floor level, so that the height of the water tank 1 cannot exceed the level of a common floor, and in consideration of the purpose of pressure reduction, the water tank not only meets the water pressure requirement in the specification, but also has a certain height, otherwise, too small water pressure also causes the condition of insufficient water pressure and small water flow. The volume of the tank 1 is in this embodiment set with 0.5 x 0.5m, the critical water level height is 250mm.

The secondary overflow pipe 31 is made of DN50, and the distance between the portion of the secondary overflow pipe located in the water surface and the critical liquid surface is 150mm. A manhole 6, which is 0.2×0.2m in size, is provided at the top of the tank 1, and is normally in a capping and locking state. The top of the water tank 1 is also provided with a vent pipe 7 which is made of DN50 material and has a height of 300mm. The water supply pipe 22 is made of DN40, the first water drain pipe 32 is made of DN50, and the second water drain pipe 4 is made of DN 32.

The water supply assembly 2 includes a first valve assembly 21 provided in a water supply pipe 22 in the water supply assembly 2, the first valve assembly 21 being capable of controlling the connection between water supplied into the water supply pipe 22 and the water tank 1. The valve clack 2132 of the float valve 213 is arranged on the liquid level so that it can move up and down along with the water level change of the liquid level, the water meter 212 is arranged on the side of the float valve 213, which is positioned in the water supply pipe 22, the main valve 211 is arranged in the direction of the side, away from the water meter 212, of the water supply pipe 22, and the main valve 211 can be a gate valve or a butterfly valve.

One end of the auxiliary overflow pipe 31 goes deep into the water tank 1 so that the height of one end of the auxiliary overflow pipe 31 in the water tank 1 is the same as the critical height of the liquid surface, and the other end of the auxiliary overflow pipe 31 merges into the main overflow pipe 3.

The first drain pipe 32 is provided at the bottom of the water tank 1, and is internally provided with a second valve 321 for controlling on-off, one end of which is incorporated into the main overflow pipe 3.

The second drain pipe 4 is provided at the other end of the bottom of the tank 1, and is internally provided with a third valve 41 for controlling on-off, and one end thereof is incorporated into the header pipe 5.

Before water supply is performed, water in the water tank 1 needs to be emptied, and thus, the remaining water in the water tank 1 needs to be discharged to the outside through the main overflow pipe 3 communicating with the first drain pipe 32 by opening the second valve 321 so that the remaining water is introduced into the first drain pipe 32.

After the water tank 1 is emptied, the main valve 211 is opened to supply water to the water tank 1, and after the water in the water tank 1 reaches the critical water level, the valve clack 2132 floats upwards along with the water level and transmits a signal back to the controller 2131, so that the float valve 213 is closed after the water level reaches the critical water level, and the water supply is closed. After the water level of the supplied water exceeds the critical level, the water above the critical level flows into the secondary overflow pipe 31, and is discharged to the outside through the primary overflow pipe 3 connected to the secondary overflow pipe 31.

When laboratory water is used, the third valve 41 is opened, the water tank 1 supplies water to the manifold 5 through the second drain pipe 4, and water flows through the manifold 5 to the respective water nozzles. When water is used in a laboratory, the real-time water level can drop, so that the liquid level of the real-time water level can be lower than the critical liquid level, at the moment, the valve clack moves downwards along with the liquid level, the ball float valve 213 is opened by the control part, and water in the water supply pipe 22 is introduced into the water tank 1, so that the real-time water level in the water tank can be maintained near the critical water level, the water supply pipe network supplies water to the water tank 1, and the water supply of the water tank 1 to each water nozzle reaches dynamic balance, so that the water quantity of the water nozzle can be ensured, and the water pressure requirement in the specification is met.

The top of the water tank 1 is provided with the ventilation pipe 7, so that the internal environment of the water tank 1 is the same as the external environment, the generation of microorganisms and bacteria is reduced, and the water tank can be emptied when used for laboratory water, thereby ensuring the water quality.

Compared with the prior art, the utility model has the advantages that: the water tank 1 is arranged at the height of three meters from the ground, so that the pressure requirement in the specification is met; the floating ball valve 213 is arranged in the water supply pipe 22, so that the water level in the water tank 1 is in a dynamic balance state during water supply, and the requirement of the water outlet quantity of the water nozzle is met; the utility model can perform the emptying operation before the experimental water, and the top of the water tank 1 is provided with the vent holes to prevent the generation of microorganisms and bacteria, thereby ensuring the requirement of water quality.

The foregoing description of the embodiments of the present utility model is merely illustrative of the technical solutions of the present utility model and not limiting thereof, and it should be understood that modifications and substitutions can be made by those skilled in the art without departing from the inventive concept of the present utility model, and all such modifications and substitutions shall fall within the scope of the appended claims. In this case, all details may be replaced with equivalent elements, and the materials, shapes and sizes may be arbitrary.
