Description

Technical Field

[0001] The utility model relates to the technical field of bend storage pipes, in particular to a bend storage pipe for a water tank. Background Art

[0002] The bend pipe is one of the main accessories in the drainage system of a building. It has a water seal structure of a certain height inside, which can not only prevent the gas in the drainage pipe system from entering the room, but also play a certain buffering effect.

A filter is provided so that object particle residues poured into the pool after the experiment cannot pass through the water trap joint, thus avoiding blockage caused by object particle residues in the pipeline. A water trap joint is provided to prevent highly corrosive liquids from directly entering the drain pipe, causing chemical reactions in the drain pipe, causing water leakage in the pipeline, and the experimental wastewater will pollute the environment. A water trap joint that is easy to disassemble is provided, thus making it convenient for users to install and disassemble the water trap joint.

[0004] In the above technical solution, a water storage joint is provided to cache the sewage in the pipe system.

[0031] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-3 As shown, a water tank bend pipe of the present invention comprises a sealing box 1 and a filter screen 2.

[0033] Among them, the sealing box 1 is the main structure of the storage bend pipe, which includes a hollow box 11, an inlet pipe 12, an outlet pipe 13 and a boss 14. The hollow box 11 is a box-shaped structure with a cavity inside; the inlet pipe 12 and the outlet pipe 13 are both fixed on the hollow box 11, the inlet pipe 12 is connected to the indoor pipe, and the outlet pipe 13 is connected to the drainage pipe; the boss 14 is fixedly arranged on the bottom side of the hollow box 11 and is arranged below one end of the inlet pipe 12 in the hollow box 11. After the indoor sewage enters the hollow box 11 through the inlet pipe 12, it first impacts the boss 14 and then is discharged from the hollow box 11 through the outlet pipe 13; there are usually impurities in the sewage, and some of the impurities will accumulate and settle on the bottom side of the hollow box 11. In order to prevent the sewage in the inlet pipe 12 from turning over these impurities, the boss 14 is spaced apart from the circumferential side of the hollow box 11, so that the impurities accumulate in the cavity between the boss 14 and the hollow box 11.

[0034] The filter screen 2 is used to block impurities in the sewage in the storage bend pipe to prevent them from entering the drainage pipe along the outlet pipe 13. The filter screen 2 is fixedly arranged between the hollow box 11 and the water inlet pipe 12. A filter hole 201 is opened inside the filter screen 2, and the water inlet pipe 12 and the outlet pipe 13 are connected through the filter hole 201; because the impurities in the sewage accumulate in the cavity between the boss 14 and the hollow box 11, the sewage in the water inlet pipe 12 will not blow the impurities between the boss 14 and the hollow box 11 when entering the hollow box 11, thereby reducing the filtering burden of the filter screen 2 and improving the cleanliness of the storage bend pipe.

[0035] like Figure 1 As shown, a buffer groove 101 is provided on one side of the boss 14 close to the water inlet pipe 12. When the sewage in the water inlet pipe 12 enters the hollow box 11, it is first buffered in the buffer groove 101 and the flow direction of the sewage is changed, making it easier for the sewage to flow upward rather than flowing into the cavity between the boss 14 and the hollow box 11, thereby enhancing the cleanliness of the storage bend pipe.

[0036] Similarly, it is preferred that the water inlet pipe 12 is arranged in a vertical direction, and the buffer tank 101 is arranged coaxially with the water inlet pipe 12, so as to enhance the buffering effect of the buffer tank 101 on the sewage in the water inlet pipe 12.

[0037] In order to allow the sewage entering the buffer tank 101 to flow to the filter screen 2 better, it is preferred that the inner diameter of the buffer tank 101 gradually increases from bottom to top, and the outer diameter of the water inlet pipe 12 is smaller than the inner diameter of the buffer tank 101 .

[0038] like Figure 1As shown, the outlet pipe 13 is arranged in the horizontal direction and is arranged above one end of the water inlet pipe 12 in the hollow box 11. When sewage flows through the storage bend pipe, it is affected by the height difference between the outlet pipe 13 and the water inlet pipe 12, and a water seal will be generated in the hollow box 11, thereby preventing air or mosquitoes in the drainage pipe from entering the room.

[0039] In order to increase the filtration area of the filter screen 2 and improve the filtration efficiency of the present bent pipe, Figure 3 As shown, the filter screen 2 is preferably a conical structure, and the outer diameter of the filter screen 2 gradually increases from bottom to top, so that the impurities blocked by the filter screen 2 move toward the edge of the hollow box 11 so as to enter between the boss 14 and the hollow box 11 for accumulation.

[0040] like Figure 2 and Figure 3 As shown, the hollow box 11 includes an upper box body 111, a lower box body 112 and a sealing ring 113, and the water inlet pipe 12 and the water outlet pipe 13 are arranged on the upper box body 111; the lower box body 112 is detachably fixed to the upper box body 111, and the boss 14 is arranged on the lower box body 112; the filter screen 2 is slidably arranged on the outside of the water inlet pipe 12 and is clamped between the lower box body 112 and the upper box body 111. It is preferred that the lower box body 112 and the upper box body 111 are connected by threaded cooperation, and the top of the lower box body 112 is located inside the upper box body 111, and the sealing ring 113 is abutted and arranged between the lower box body 112 and the upper box body 111. Using this structural design, it is not only convenient to disassemble and maintain the filter screen 2, but also can improve the cleaning efficiency of the hollow box 11.

[0041] like Figure 1 As shown, the boss 14 and the hollow box 11 are integrally formed and continuously arranged, that is, the edge of the bottom of the boss 14 is integrally formed with the bottom side of the hollow box 11, which not only facilitates the processing and forming of the sealing box 1, but also saves processing costs.

[0042] The working principle of the utility model of a water tank bend pipe is as follows:

[0043] After the sewage in the indoor pipe enters the hollow box 11 along the water inlet pipe 12, it first flows into the buffer tank 101 for buffering, and then flows into the drainage pipe through the filter holes 201 and the outlet pipe 13 in sequence; during this period, impurities in the sewage are blocked by the filter mesh 2 and accumulated in the cavity between the boss 14 and the hollow box 11, and will not be blown away by the sewage in the water inlet pipe 12.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
