Embodiment 1
[0029] Such as figure 1 , 2 , 3, and 4, the building embedded drainage concentrator according to the present invention is composed of a vertical pipe drainage section 1, a horizontal pipe drainage collection section 2 and a water seal member 3. The vertical pipe drainage section 1 is connected up and down; the horizontal pipe drainage collection section 2 is located on one side of the vertical pipe drainage section 1, and the hollow part communicates with the hollow part of the vertical pipe drainage section 1, and the horizontal surface 9 of the horizontal pipe drainage collection section 2 and The lower inner wall is flat, and the included angle with the upper interface 4 of the vertical pipe drainage section 1 is 90°; the cross-sectional area of the opening 10 at the connection between the horizontal pipe drainage collection section 2 and the vertical pipe drainage section 1 is 3000mm 2 The horizontal pipe drainage converging section 2 connected to the riser drainage sec...
Embodiment 2
[0031] Such as Figure 5 As shown, the water seal member lower part 20 and the water seal member middle part 19 of the building embedded drainage concentrator according to the present invention are not integral members, and the inner diameter of the water seal member middle part 19 lower end 31 is larger than the water seal member lower part 20 lower end The outer diameter of the outer diameter is less than the outer diameter of the water seal member bottom 20 upper end 33, and there is a groove one 34 on the outer diameter of the water seal member bottom 20 upper end 33, and a rubber ring 35 is arranged in the groove one 34, and the rubber ring 35 is positioned at the water seal member bottom 20 upper end 33. In the inner wall of the middle part 19 of the sealing body member; when it is necessary to overhaul and clear the drainage collection section 2 of the horizontal pipe, only the lower part 20 of the water sealing body member needs to be pulled out from the middle part 19 ...
Embodiment 3
[0033] Such as Figure 5 , 6 As shown, the water seal component lower part 20 and the water seal component middle part 19 of the building embedded drainage concentrator according to the present invention are not integral components, and the inner diameter of the water seal component middle part 19 lower end 31 is 70 mm, and the water seal component lower part The outer diameter of the lower end of 20 is 68 mm, the outer diameter of the upper end 33 of the lower part 20 of the water sealing body member is 86 mm, the upper surface of the lower end 31 of the middle part 19 of the water sealing body member is in contact with the lower surface of the upper end 33 of the lower part 20 of the water sealing body member, and both are plane , there are two grooves 2 39 on the lower end 31 of the middle part 19 of the water seal member, the diameter of the groove 2 39 is 76 mm, and the arc length is 10 mm. The outer diameter is 75mm, the arc length is 9mm, the upper and lower thickness ...
