In people's production life, generally need discharge domestic waste water through the pipeline, stop up to lead to liquid from the main line overflow in order to solve when the main line, set up overflow pipe usually at the main line, discharge liquid through overflow pipe, avoid the main line to stop up and lead to the building to damage, but because overflow pipe and main line are the on-state always, so can lead to worm or mouse etc. to get into indoorly through overflow pipe.
The utility model provides an anti-overflow flow pipeline structure, fig. 1 to fig. 2 are the utility model provides an anti-overflow flow pipeline structure's embodiment.
Referring to fig. 1 to 2, the overflow prevention pipeline structure 100 includes a main pipeline 1, an overflow pipeline 2 and an overflow baffle 3, the main pipeline 1 is sequentially provided with a water inlet a, a water outlet b and an overflow port c arranged between the water inlet a and the water outlet b along the vertical direction, a connecting pipeline section 11 is arranged on the side wall of the main pipeline 1 in an extending manner from the periphery of the overflow port c, one end of the overflow pipeline 2 is communicated with the connecting pipeline section 11, and the overflow baffle 3 is rotatably installed in the connecting pipeline section 11 to unidirectionally conduct the connecting pipeline section 11, so that overflow liquid in the connecting pipeline section 11 is guided into the overflow pipeline 2 and discharged.
The utility model provides an among the technical scheme, stop up when trunk line 1 and lead to the liquid level in trunk line 1 to rise, overflow liquid overflow in the trunk line 1 extremely during the connecting pipe section 11, overflow liquid promotes overflow baffle 3 rotates, makes connecting pipe section 11 one-way switches on, overflow liquid in the connecting pipe section 11 is leading-in extremely discharge in the overflow pipeline 2, after overflow liquid discharges, overflow baffle 3 resets closedly connecting pipe section 11, so avoid overflow pipeline and main line to be the on-state always, so avoid worm or mouse etc. to get into indoorly through overflow pipeline 2.
Referring to fig. 1 and 2, the connecting pipe section 11 is inclined upward, the overflow baffle 3 extends upward and downward, the lower end of the overflow baffle 3 is rotatably mounted on the inner wall surface of the connecting pipe section 11, so as to avoid that liquid enters the connecting pipe section 11 when the main pipe 1 is not blocked, at this time, because the connecting pipe section 11 is inclined upward, the liquid can flow back into the main pipe 1, when the main pipe 1 is blocked, the overflow liquid enters the connecting pipe section 11, the water pressure of the overflow liquid pushes the overflow baffle 3 to rotate, because the lower end of the overflow baffle 3 is rotatably mounted on the inner wall surface of the connecting pipe section 11, when the water pressure of the liquid entering the overflow pipe 2 is high, the upper end of the overflow baffle 3 can be pushed to rotate to be parallel to the connecting pipe section 11, therefore, the conduction opening of the overflow baffle 3 for conducting the connecting pipe section 11 is the largest, the resistance borne by the overflow liquid during discharge is reduced, and the overflow liquid can be discharged quickly.
Referring to fig. 2, an elastic reset piece 4 is arranged between the overflow baffle 3 and the connecting pipe section 11, the elastic reset piece 4 resets to close the overflow baffle 3 to the connecting pipe section 11, so that the connecting pipe section 11 is closed after overflow liquid is discharged from the overflow pipeline 2, insects or mice are prevented from entering the connecting pipe section, and the structure is simple.
Specifically, elasticity resets 4 and includes reset spring, reset spring's one end is fixed in overflow baffle 3's upper end, reset spring's the other end is fixed in connect the pipeline section 11 with the corresponding internal face in overflow baffle 3 upper end, so set up, through reset spring elastic force pulls overflow baffle 3 resets to the closure connect the pipeline section 11, simple structure, it is effectual.
Further, connect the pipeline section 11 with 2 threaded connection of overflow pipeline, so set up, be convenient for connect the pipeline section 11 with 2 dismouting of overflow pipeline, and work as when trunk line 1 blocks up, can pass through overflow pipeline 2 discharges overflow liquid, work as overflow liquid discharges the back, will overflow pipeline 2 with connect the pipeline section 11 split, certainly connect the pipeline section 11 mediation trunk line 1, easy operation, it is effectual.
Specifically, connect pipeline section 11 and include external screw thread pipeline section 111, the protruding cyclic annular butt platform 1111 that is equipped with in external screw thread pipeline section middle part, overflow pipe 2 includes internal screw thread pipeline section 21, internal screw thread pipeline section 21 with external screw thread pipeline section 111 threaded connection, the internal screw thread pipeline section corresponds cyclic annular butt platform 1111 is provided with annular groove 211, install the sealing ring in the annular groove 211, the sealing ring outer lane be used for with the sealed butt of cyclic annular butt platform 1111, through the sealing ring is to threaded connection connect pipeline section 11 with overflow pipe 2 seals, avoids connect pipeline section 11 with overflow pipe 2 junction takes place to leak, and is effectual.
In order to avoid the overflow baffle 3 being opened by mistake, the surface of the periphery of the overflow baffle 3 and the inner wall of the connecting pipe section 11 are abutted is set as a friction surface, when the water pressure of the overflow liquid is greater than the friction force received by the overflow baffle 3, the overflow baffle 3 is conducted to the connecting pipe section 11 in a one-way mode, so that the overflow liquid in the connecting pipe section 11 is led into the overflow pipeline 2 to be discharged, and the effect is good.
Referring to fig. 1, the overflow pipeline 2 includes a bent pipe section 22, a first overflow dividing pipe section 23 and a second overflow dividing pipe section 24, one end of the first overflow dividing pipe section 23 is communicated with the connecting pipe section 11, the other end is communicated with one end of the bent pipe section 22, the other end of the bent pipe section 22 is communicated with one end of the second overflow dividing pipe section 24, and the other end of the second overflow dividing pipe section 24 is used for draining liquid.
Specifically, the bending pipe section 22 is arc-shaped, so that the overflow liquid in the overflow pipeline 2 can be smoothly discharged, the bending pipe section 22 is prevented from being blocked, and the effect is good.
Further, the bent pipe section 22 is bent downward, so as to prevent the overflow liquid in the second overflow dividing pipe section 24 from flowing backwards.
Referring to fig. 1, the overflow port c is provided with a filter screen 5, and large-particle substances are filtered by the filter screen 5, so that the overflow pipeline 2 is prevented from being blocked due to the large-particle substances entering the overflow pipeline 2.
In order to avoid overflow liquid to flow back extremely trunk line 1, connect the protruding backstop post 112 that is equipped with of pipeline 11 lateral wall, backstop post 112 with overflow baffle 3 orientation a side butt of overflow mouth c, so set up, work as when overflow liquid falls back, because overflow baffle 3 with backstop post 112 offsets, and is closed connect pipeline section 11, thereby stop overflow liquid falls back to trunk line 1, it is effectual.
The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
