Description

Technical Field

[0001] The utility model relates to the technical field of pressure tank protection, in particular to a side leakage prevention pressure tank. Background Art

[0002] Pressure tanks are used in closed water circulation systems to balance water volume and pressure, avoiding frequent opening of the safety valve and frequent water replenishment by the automatic water replenishment valve. In addition to accommodating expansion water, the expansion tank can also serve as a water replenishment tank. The expansion tank is filled with air to obtain a larger volume to accommodate the expansion water. The high and low pressure expansion tanks can use their own pressure to replenish water to the pressure stabilization system in parallel. Currently, existing pressure tanks do not have devices to prevent side leakage when in use. Pressure tanks are easily bumped during transportation, handling or installation, which can cause damage to the pressure tank and side leakage.

[0003] A Chinese utility model patent with the publication number CN217329432U specifically discloses a side leakage prevention pressure tank, including a tank body, handles on both sides of the tank body, a support frame at the lower end of the tank body, a ring bracket No. 1 at the lower end of the tank body, a support leg No. 1 at the lower end of the ring bracket No. 1, a ring bracket No. 2 at the lower end of the support leg No. 1, a support leg No. 2 at the lower end of the ring bracket No. 2, a base at the bottom of the support leg No. 2, and a rubber pad at the outside of the tank body. The side leakage prevention pressure tank can be isolated from direct contact with the ground or other transportation tools during transportation by installing a rubber pad movably around the outside of the tank body, thereby preventing the tank body from hitting sharp objects to damage and wear the tank body and causing side leakage of the tank body. By fixing a welded base at the bottom end of the support leg No. 2, the base can make the support frame more stable, so that the tank body can be stably placed inside the support frame without tipping over, thereby achieving the beneficial effect of preventing side leakage.

[0004] In the above patent, the protection of the tank body is achieved only by the rubber pad, which cannot fully protect the tank body, and there is no anti-corrosion treatment on the tank body, which is not convenient for long-term use of the tank body.

[0005] Therefore, it is necessary to invent a kind of anti-side leakage pressure tank to solve the above problems. Utility Model Content

[0025] In the above technical solution, the filler 3 is filled in the upper end of the cavity formed between the outer shell 1 and the tank body 2. The outer shell 1 is fixedly connected to the tank body 2 through the filler 3 and the shockproof block 4. The filler 3 is made of foam, the shockproof block 4 is made of rubber, and the shape is a prism, and is evenly distributed around the cavity.

[0026] Specifically, by providing the filler 3 and the shockproof block 4, the protective device is prevented from being bumped during transportation and causing side leakage of the tank body.

[0027] The water injection pipe 10 extends to the inside of the sealing ring 6 , the water bag 5 is fixedly connected to the inner wall of the tank body 2 through the sealing ring 6 , and the air intake pipe 7 penetrates and connects the outer shell 1 and the tank body 2 .

[0035] How this utility works:

[0036] Refer to the instruction manual Figure 1-3 First, before the device leaves the factory, a proper amount of nitrogen is injected into the tank body 2 through the air valve 9. The injected nitrogen needs to reach 0.2 MPa when the water bag 5 is filled with water. The water valve 11 is connected to the water network to automatically inject water into the water bag 5 until the water bag 5 is full. When the water bag 5 is full of water, if the value of the pressure gauge 8 is observed to reach 0.2 MPa, nitrogen should be immediately injected into the tank body 2 through the air valve 9 until the value of the pressure gauge 8 reaches 0.2 MPa. Because the device has been operating in a relatively humid environment, it is easy to cause corrosion to the tank body 2 or its welding parts. When the tank body 2 or its welding parts produce an oxidation reaction with the water and oxygen in the environment, the metal strip 21 transmits the electrons lost during the oxidation reaction to the tank body 2 or its welding parts through electrical connection. Finally, the metal strip 21 will cause itself to undergo an oxidation reaction when protecting the tank body 2. The status of the metal strip 21 can be observed from the observation port 16, and the user can replace it in time.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
