Embodiment 1

[0028] see Figure 1-7 As shown, a domestic sewage collection device includes a first water pipe 1 and a second water pipe 2, and the opposite sides of the first water pipe 1 and the second water pipe 2 communicate through a connector 3, and the connector 3 is far away from the second water pipe. One side of the water pipe 2 is fixedly connected with the first sealing edge 4, the diameter of the outer end of the first sealing edge 4 is larger than the diameter of the outer end of the first water pipe 1, and the end of the connector 3 far away from the first sealing edge 4 is tightly connected with the thread. The second sealing edge 5, the outer end diameter of the second sealing edge 5 is greater than the outer end diameter of the first water pipe 1, and the first water pipe 1 and the second water pipe 2 are respectively provided with a A sealing cover 13 matching the sealing edge 4 and the second sealing edge 5, wherein one sealing cover 13 is threaded with a locking bolt 17...

Embodiment 2

[0037] see Figure 8 As shown in Comparative Example 1, as another embodiment of the present invention, the inner end wall of the sealing gasket 14 is provided with a ring of sealing gaskets 30. Through the setting of the sealing gasket 30, the connection between the sealing gasket 14 and the first The airtightness of the sealing edge 4 and the second sealing edge 5 improves the overall airtightness of the connecting head 3 .

[0038] Working principle, by turning the screw rod 27 to drive the moving nut 29 to adjust the two sets of vertical plates 20 and then adjust the distance between the two sets of arc sleeves 24, in the process of actual use, the first water pipe 1 and the second water pipe 1 can be strengthened. The stability of the connection between the water pipes 2 avoids the phenomenon that the two are separated due to the vibration of the high-pressure water flow inside. By adjusting the bolt 22, the lifting bar 23 and the setting of the arc sleeve 24, it can be c...

Abstract

The invention belongs to the technical field of domestic sewage collection, and particularly relates to a domestic sewage collection device which comprises a first water passing pipe and a second water passing pipe, the opposite sides of the first water passing pipe and the second water passing pipe are communicated through a connector, and the side, away from the second water passing pipe, of the connector is fixedly communicated with a first sealing edge. The diameter of the outer end of the first sealing edge is larger than that of the outer end of the first water passing pipe, the end, away from the first sealing edge, of the connector is in threaded sealing connection with a corresponding second sealing edge, and the diameter of the outer end of the second sealing edge is larger than that of the outer end of the first water passing pipe. The sealing cover and the sealing gasket are matched with the inclined sealing face and the arc-shaped sealing ring to achieve multi-stage plugging, the sealing performance of the connecting position of the water passing pipe is improved, when dismounting and mounting are needed, the whole sewage collecting pipeline does not need to be closed, only the adjusting rod needs to be screwed, the second sealing edge and the second water passing pipe can be dismounted, and convenience is achieved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage collection, in particular to a domestic sewage collection device. Background technique [0002] Domestic sewage is the wastewater discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets, etc. Domestic sewage is exported from each household through pipelines , and finally transported to the sewage treatment plant in a unified manner. In fact, before the treatment of domestic sewage, it is often necessary to use the corresponding domestic sewage collection device to collect these domestic sewage. [0003] The existing domestic sewage collection device must contain multiple pipes connected in sequence. When disassembling or repairing the pipes, the staff often need to find the corresponding shut-off valve to close, which is inconvenient. Anoth...
