Anti-blocking same-layer drainage pipe fitting with water seal

Abstract

An anti-blocking same-layer drainage pipe fitting with a water seal comprises a main vertical pipe, a branch pipe and the water seal, the branch pipe is connected with the main vertical pipe through the water seal, the water seal is of a U-shaped cavity structure partitioned by a middle partition plate, and a water inlet and an overflow port are formed in the positions, on the outer walls of cavities on the two sides of the middle partition plate, of the water seal respectively; the water inlet is connected with a branch pipeline; the overflow port is enclosed by a horizontal pipe wall at the upper part, a side pipe wall and a vertical pipe wall at the lower part; the vertical pipe wall forms an overflow baffle; the water seal is additionally provided with a drainage area at an overflow port, the drainage area is located between the main vertical pipe and the water seal and extends outwards through a horizontal pipe wall, and the drainage area is connected to the side wall of the main vertical pipe after obliquely downwards and outwards extending with an inclined wall externally connected with an overflow baffle; a water passing opening is formed in the side wall of the main vertical pipe; the side pipe wall extends and then is connected with the edges of the two sides of the water passing opening. When water flow in the main vertical pipe rotates and flows downwards along the pipe wall, due to the fact that the overflow baffle and the inclined wall are arranged in the drainage area, objects in the water flow are not prone to being accumulated at the water passing opening to cause pipeline blockage. Meanwhile, the water flow in the branch pipe passes through the water seal, bypasses the overflow baffle, enters the drainage area and is downwards drained into the main vertical pipe along the inclined wall, the water flow is released in the drainage area and does not collide with the water flow in the main vertical pipe, and flowing is smoother. The invention solves the technical problems of pipeline blockage and unsmooth flow of the same-layer drainage pipe fitting with the water seal.

The water seal is combined with the side wall of the main pipe and a transverse cut is opened on the upper side wall of the joint point, so that the water in the branch pipe flows into the main pipe. The water in the main pipe rotates and flows downward along the pipe wall. There may be objects hanging in the water at the transverse cut of the main pipe, causing pipe blockage or poor flow. Therefore, the above technical problems need to be solved. Summary of the invention

[0006] The water seal 104 adds a discharge area 107 at the overflow port, 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 to the edges on both sides of the water outlet 101.

[0011] Beneficial effects of the present invention:

[0012] The present invention provides a same-floor drainage pipe fitting with anti-clogging and water seal, wherein a discharge area is added at the overflow port 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 oblique wall connected to the outside of the overflow baffle obliquely downward and outward, and is provided with a water outlet on the side wall of the main riser, and the lower end of the oblique wall intersects and smoothly connects at the bottom edge of the water outlet; the upper end of the oblique wall is connected to the overflow baffle, and the side pipe wall is extended to connect to the edges on both sides of the water outlet. When the water flow in the main riser rotates and flows downward along the pipe wall, since the overflow baffle and the oblique wall are provided in the discharge area, objects in the water flow are not easy to accumulate at the water outlet and block the pipe. At the same time, the water flow in the branch pipe passes through the water seal and bypasses the overflow baffle, enters the discharge area, and is discharged downward into the main riser along the oblique wall. The water flow is released in the discharge area and will not collide with the water flow in the main riser, so the flow is smoother. BRIEF DESCRIPTION OF THE DRAWINGS
