Description

Technical Field

[0001] The utility model relates to the field of drainage systems in construction projects, in particular to an anti-clogging and water-sealed same-floor drainage pipe fitting. Background Art

[0002] Existing drainage pipes with water seals consist of a main pipe and a branch pipe. A water seal is installed between the main and branch pipes. The seal is bonded to the sidewall of the main pipe, and a transverse cutout is made in the sidewall above the junction, allowing water from the branch pipe to flow into the main pipe. However, water in the main pipe swirls downward along the pipe wall, and objects hanging in the transverse cutout of the main pipe could cause pipe blockage or poor flow. Therefore, a solution to these existing technical problems is needed. Utility Model Content

[0003] The utility model provides an anti-clogging and water-sealed same-floor drainage pipe fitting, which aims to solve the technical problems of pipeline blockage and poor flow in the water-sealed same-floor drainage pipe fitting.

[0004] The technical solution of the present utility model is achieved as follows:

[0005] A same-floor drainage pipe fitting with anti-clogging and water seal, comprising a main riser, a branch pipe, and a water seal, wherein the branch pipe is connected to the main riser via the water seal, the water seal being a U-shaped chamber structure formed by a middle partition, the water seal having a water inlet and an overflow port respectively provided on the outer walls of the chamber on both sides of the middle partition; the water inlet being connected to the branch pipe; the overflow port being surrounded by an upper horizontal pipe wall, a side pipe wall, and a lower vertical pipe wall; the vertical pipe wall forming an overflow baffle 106; and characterized in that:

[0006] The water seal 104 adds a discharge area 107 at the overflow outlet, and the discharge area 107 is located between the main riser 1 and the water seal 104. The discharge area extends outward through the horizontal pipe wall 108 and extends obliquely downward and outward through the inclined wall 102 connected to the outside of the overflow baffle 106, and is connected to the side wall of the main riser; a water outlet 101 is provided on the side wall of the main riser, and the lower end of the inclined wall 102 intersects and smoothly connects at the bottom edge of the water outlet; the height of the upper edge of the water outlet 101 is not higher than the upper edge of the overflow baffle 106; the upper end of the inclined wall is connected to the overflow baffle 106 and is lower than the outer wall of its upper edge, and the side pipe wall is extended to connect the two side edges of the water outlet 101.

[0007] The anti-clogging and water-sealed same-layer drainage pipe fitting is provided with an inspection hole 103 on the horizontal pipe wall 108 just above the water seal 104 and is adjacent to the middle partition.

[0008] The anti-clogging and water-sealed same-layer drainage pipe fitting is characterized in that the height of the water outlet 101 is lower than the height of the branch pipe.

[0009] In the aforementioned anti-clogging and water-sealed same-floor drainage pipe fitting, the branch pipe opening 105 is connected to other pipe fittings via a pipe clamp 2 .

[0010] In the anti-clogging and water-sealed same-floor drainage pipe fitting, the overflow baffle 106 is directly arranged above the inclined wall 102 and integrally connected thereto, and the water seal and the main riser 1 share the same vertical pipe wall.

[0011] Beneficial effects of the utility model:

[0012] The utility model provides a same-floor drainage pipe fitting that is anti-clogging and has a water seal. A discharge area is added to the overflow outlet of the water seal. The discharge area is located between the main riser and the water seal and is connected to the side wall of the main riser after extending outward through the horizontal pipe wall and the inclined wall connected to the outside of the overflow baffle. The lower end of the inclined wall intersects and smoothly connects at the bottom edge of the water outlet; the upper end of the inclined wall is connected to the overflow baffle, and the side pipe wall extends to connect to the two side edges of the water outlet. When the water flow in the main riser rotates and flows downward along the pipe wall, due to the overflow baffle and inclined wall in the discharge area, objects in the water flow are less likely to accumulate at the water outlet and clog the pipe. At the same time, the water flow in the branch pipe passes through the water seal and bypasses the overflow baffle, then enters the discharge area and discharges downward along the inclined wall into the main riser. The water flow is released in the discharge area and does not collide with the water flow in the main riser, resulting in a smoother flow. BRIEF DESCRIPTION OF THE DRAWINGS
