[0002] Ultrapure water, also known as UP water, refers to water with a resistivity of 18 MΩ*cm (25°C). In this kind of water, there are almost no impurities except water molecules, let alone bacteria, viruses, organic substances such as chlorinated dioxins, and of course no mineral trace elements required by the human body, that is, water that has almost removed all atoms except oxygen and hydrogen.

[0003] However, in the existing technology, the storage of ultrapure water is relatively complicated. When ultrapure water comes into contact with air, it will cause air to enter the ultrapure water, affecting the quality of ultrapure water. Generally, a certain amount of nitrogen is filled into a sealed water tank, and the nitrogen pressure in the water tank is not greater than 80 Kpa. Nitrogen is an inert gas that can prevent other substances such as carbon dioxide from dissolving in the water and affecting the water quality, ensuring that the water in the water tank is not secondarily polluted and the water quality does not decline.

[0004] However, the current water tank lacks the recovery of nitrogen after use, and disposable use will cause waste of resources. Therefore, an environment-friendly and energy-saving electronic-grade ultrapure water sealed water tank is proposed to solve the above problems. Content of the Utility Model

[0012] Compared with the related art, an environmentally friendly and energy-saving electronic-grade ultrapure water sealed water tank provided by the present invention has the following beneficial effects:

[0013] The present invention provides an environmentally friendly and energy-saving electronic-grade ultrapure water sealed water tank. By screwing the tank cover onto the top of the water tank body, during the process, the sealing plate and the sealing groove are gradually sealed and fitted together to form a sealing cavity by the sealing plate and the sealing groove. At the same time, the rubber gasket is extruded, and the deformation of the rubber gasket completely fills the sealing cavity, so that the water tank body has a good sealing effect. Nitrogen is injected into the water tank body through the inflation pipe, and the nitrogen inside the water tank body is recovered by the air extraction pipe, making the sealed storage of ultrapure water more environmentally friendly and saving the storage cost.

[0014] The present invention provides an environmentally friendly and energy-saving electronic-grade ultrapure water sealed water tank. When injecting nitrogen into the water tank body through the inflation pipe, it will push the first one-way valve to open, so that nitrogen can smoothly enter the water tank body through the first one-way valve. After use, sleeving the sealing cover on the top of the inflation pipe can achieve a good dust-proof and sealing effect. When the nitrogen inside the water tank body is pumped out and recovered through the air extraction pipe, it drives the second one-way valve to open, so that nitrogen can be smoothly pumped out and recycled from the water tank body through the second one-way valve.

Specific implementation mode

[0020] Please refer to Figures 1 - 4 , the present utility model provides a technical solution, including a water tank body 1, a water injection port 11 is opened at the lower end of the water tank body 1, a tank cover 12 is detachably installed at the upper end of the water tank body 1, a sealing structure is arranged between the water tank body 1 and the tank cover 12, a charging pipe 13 and an air extraction pipe 15 are fixedly installed through the top of the tank cover 12, the sealing structure includes a sealing groove 18, a rubber gasket 19 is filled inside the sealing groove 18, a sealing plate 25 is concavely arranged at the bottom of the tank cover 12, the sealing plate 25 is in sealing fit with the sealing groove 18, and the tank cover 12 is threadedly sleeved on the top of the water tank body 1;

[0021] By threadedly sleeving the tank cover 12 on the top of the water tank body 1, during the process, the sealing plate 25 and the sealing groove 18 are gradually in sealing fit, a sealing cavity is formed by the sealing plate 25 and the sealing groove 18, and at the same time, the rubber gasket 19 is extruded, and the sealing cavity is completely filled by the deformation of the rubber gasket 19, so that the water tank body 1 has a good sealing effect, and nitrogen is injected into the water tank body 1 through the charging pipe 13, and the nitrogen inside the water tank body 1 is recovered through the air extraction pipe 15, so that the sealed storage of ultrapure water is more environmentally friendly and the storage cost is saved.

[0022] A first one-way valve 16 is fixedly arranged inside the charging pipe 13, the charging pipe 13 is communicated with the inside of the water tank body 1 through the first one-way valve 16, a second one-way valve 17 is fixedly arranged inside the air extraction pipe 15, the air extraction pipe 15 is communicated with the inside of the water tank body 1 through the second one-way valve 17, and a sealing cover 14 is threadedly sleeved at the upper end of the charging pipe 13;

[0023] When injecting nitrogen into the water tank body 1 through the charging pipe 13, the first one-way valve 16 will be pushed open, so that nitrogen can smoothly enter the inside of the water tank body 1 through the first one-way valve 16. After use, sleeving the sealing cover 14 on the top of the charging pipe 13 can achieve a good dust-proof and sealing effect, and when extracting and recovering the nitrogen inside the water tank body 1 through the air extraction pipe 15, the second one-way valve 17 is driven to open, so that nitrogen can be smoothly extracted and recycled from the water tank body 1 through the second one-way valve 17.

[0024] A through slot 22 is formed transversely through the upper end of the exhaust pipe 15, and a connecting port 21 is formed vertically through the interior of the through slot 22. An adjustment plate 2 is slidably mounted on the inner wall of the through slot 22, and an exhaust hole 27 is formed through the surface of the adjustment plate 2. The connecting port 21 is connected to the interior of the exhaust pipe 15 through the exhaust hole 27.

[0025] When it is necessary to use the exhaust pipe 15 to extract the nitrogen inside the water tank body 1, the sliding adjustment plate 2 drives the exhaust hole 27 to align with the connecting port 21, so that the connecting port 21 can smoothly recover the nitrogen from the inside of the water tank body 1, and push the adjustment plate 2 in the opposite direction after the exhaust is completed. The adjustment plate 2 realizes a sealed separation between the connecting port 21 and the inside of the exhaust pipe 15, thereby preventing the nitrogen inside the water tank body 1 from leaking when in use.

[0026] A limit block is fixedly installed on the inner wall of the through slot 22, and a sliding groove 26 is provided on the surface of the adjustment plate 2. The sliding groove 26 is slidably sleeved on the surface of the limit block.

[0028] A slot 24 is formed in the top of the adjusting plate 2, and a rubber clamp 23 is fixedly installed on the inner wall of the through slot 22. The rubber clamp 23 is elastically clamped to the inner wall of the slot 24.

[0029] When adjusting the position of the exhaust hole 27 by sliding the adjustment plate 2, the elastic clamping of the card slot 24 and the rubber clamp head 23 enables the exhaust hole 27 to be more accurately aligned with the connecting port 21, and will not slide easily when the adjustment plate 2 is stationary, thereby achieving precise positioning of the adjustment plate 2.

[0030] The water inlet 11 is equipped with an airtight valve. The storage and discharge of ultrapure water are achieved through the water inlet 11, and the airtight valve isolates the water tank body 1 from the external environment, further reducing the mixing of ultrapure water with air inside the water tank body 1 and improving the sealing effect of the water tank body 1.
