Description

Technical Field

[0001] This utility model relates to the field of pressure tank technology, specifically to a chuck structure inside a pressure tank. Background Technology

[0002] A pressure tank is a prerequisite for a water pump to enter sleep mode. It utilizes the property that water has very low compressibility, using external force to store water in the tank. The gas is compressed and the pressure increases. When the external force is removed, the compressed gas expands and can expel the water.

[0003] Diaphragm pressure tanks completely separate air and water. Water is on one side of the rubber diaphragm, while the other side is pre-filled with air. This type of pressure tank does not have the problem of loss of aerosols and water. It can be used for a long time after a single filling. Therefore, it saves investment, simplifies the system, and expands the scope of application. It is often used for secondary water supply in high-rise buildings.

[0004] Chinese Patent Publication No. CN205530476U discloses a pressure tank, including a tank body, an air bladder liner disposed within the tank body, a water inlet pipe connected to the tank body for introducing water into the tank body, and an air inlet on the tank body for inflating the air bladder liner. The pressure tank also includes a drain pipe connected to the pressure tank for draining water, a solenoid valve disposed on the drain pipe, and a time relay connected to the solenoid valve for controlling the opening and closing of the solenoid valve. This invention uses the time relay to set a fixed time to open the solenoid valve for draining water, thereby achieving periodic discharge of stagnant water and avoiding secondary water pollution.

[0005] However, this utility model has the following problems in actual use:

[0006] There are many types of tap water supply equipment in the existing technology. One type is a water supply equipment with a pressure tank. This type of pressure tank usually adopts a capsule type, that is, a capsule is placed in the tank, and tap water is poured into the capsule. The pressure is stabilized by the elasticity of the capsule. This structure is expensive and easy to break. For a long time, the rubber material of the air bladder is tightly attached to the tank wall, making it difficult to pull out during maintenance and replacement, which is very laborious and time-consuming.

[0019] (III) Beneficial Effects

[0020] This utility model provides a chuck structure inside a pressure tank, which has the following advantages:

[0021] 1. The internal chuck structure of this pressure tank, through the cooperation of the piston and the tank body, can use its own sliding adjustment to replace the expansion and contraction of the air bladder. Therefore, even with long-term use, there will be no damage or leakage caused by repeated expansion and contraction of the air bladder after use. Furthermore, through the cooperation of the mounting groove and the cover plate, the piston can be directly removed for cleaning and maintenance after regular use, and the sealing ring can also be replaced, thereby ensuring the sealing performance of the device and ensuring the stability of the water supply.

[0022] 2. The chuck structure inside the pressure tank, through the setting of guide blocks, can assist and guide the sliding of the piston, thereby ensuring that the piston slides and adjusts along the direction of the tank. Therefore, when the pressure changes, the water pressure below drives the piston to slide upward, thereby compressing the gas in the upper part of the tank. Then, when the water is discharged, the pressure of the gas can be used to drive the piston to slide downward, squeezing the water outward. Attached Figure Description

After the cover plate 6 is closed, it can be fixed with the fixing bolt 9.

[0034] See also Figures 1 to 4 In order to assist the piston 12 in sliding under pressure, a guide block 7 is connected to the pipe on the inner side wall of the tank 1.

[0035] The inner wall of the cover plate 6 is fixedly connected to a locking block 8. The inner wall of the tank body 1 is connected to a limiting block 11 at the bottom of the outer wall of the guide block 7. A piston 12 is slidably connected to the inner wall of the tank body 1. The outer wall of the piston 12 is provided with a guide groove 13 that matches the guide block 7. The inner wall of the guide groove 13 is slidably connected to the outer surface of the guide block 7. A sealing ring 14 is fitted onto the outer surface of the piston 12. The guide block 7 provides assistance for the sliding of the piston 12 and guides the piston 12 to move in the correct direction along the inner wall of the tank body 1.

[0038] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0039] In this invention, the working steps of the device are as follows:

[0040] First, the preparatory work:

[0041] First, remove the fixing bolt 9. Then, use the push rod 10 to open the cover plate 6. Install the piston 12 into the tank 1 and ensure that all components of the pressure tank are properly installed, including the seal between the piston 12 and the sealing ring 14. Check the seal of the tank 1 and all connecting parts. Then, close the cover plate 6 and retighten the fixing bolt 9 to prevent leakage. Water can then be injected into the tank 1 through the delivery pipe 4.

[0042] Water is introduced into tank 1 and filled to an appropriate level. The water will fill the bottom of the entire tank 1, creating pressure. As water is injected, the liquid pressure inside tank 1 gradually increases. When the water pressure exceeds a certain threshold, the water pressure will push the piston 12 to move upward.

[0043] Piston 12 slides upward, compressing the upper part of the gas in the tank 1 and increasing the gas pressure. This process can achieve pressure balance between liquid and gas.

[0044] When drainage is required, the delivery pipe 4 can be connected. The pressure of the gas pushes the piston 12 to slide downward, discharging the water below through the delivery pipe 4 to the outside.

[0045] Periodically unscrew the fixing bolts 9, push the push rod 10 to open the cover plate 6, and remove the piston 12 by means of the cooperation between the mounting groove 5 and the cover plate 6 for cleaning. At the same time, check and replace the sealing ring 14 to ensure the seal with the tank body 1 and prevent leakage.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
