Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, for the utility model discloses a water supply and drainage structure for kitchen and toilet of high-rise building, including header tank 1, be responsible for 2 and communicate in the drainage of header tank 1 and be responsible for 2 drainage branch pipe 3.
The water collecting tank 1 is of a cavity structure, the upper part of the water collecting tank 1 is of a cuboid structure, and the bottom of the side wall of the upper part of the water collecting tank 1 gradually shrinks downwards along the direction far away from the side wall of the water collecting tank 1 to form a cone. An access hole 7 has been seted up at the top of header tank 1, and the setting of access hole 7 is convenient for carry out the inspection maintenance to header tank 1 inside. The main drainage pipe 2 is a vertical pipeline, and the main drainage pipe 2 penetrates the bottom of the water collecting tank 1 from the top of the water collecting tank 1 and is communicated with the water collecting tank 1.
The branch drain pipe 3 is an L-shaped pipeline, one end of the branch drain pipe 3 in the vertical direction extends out of the top of the water collecting tank 1, and one end extending out of the top of the water collecting tank 1 can be connected with a drain pipeline of a kitchen or a toilet. One end of the horizontal direction of the branch drainage pipe 3 is communicated with the main drainage pipe 2, one end of the branch drainage pipe 3 close to the main drainage pipe 2 is provided with a one-way valve 31, and the one-way valve 31 enables sewage to flow into the main drainage pipe 2 only from the branch drainage pipe 3, so that the sewage is prevented from flowing into the branch drainage pipe 3 from the main drainage pipe 2, and sewage and odor are prevented from flowing back to a kitchen or a toilet to cause pollution.
An emergency valve 32 is further arranged between the check valve 31 and the main drainage pipe 2, and the emergency valve 32 is in a normally open state when the drainage system operates normally. When the check valve 31 breaks down, the emergency valve 32 can be closed to prevent sewage and odor from flowing back to the drainage branch pipe 3 to cause pollution, and the check valve 31 can be maintained without sewage flowing from the drainage main pipe 2 to the drainage branch pipe 3.
Referring to fig. 2, the main drainage pipe 2 is communicated with a buffer tube 4, the buffer tube 4 is located inside the water collecting tank 1 and communicated with the water collecting tank 1, and the buffer tube 4 is gradually inclined upward along a direction away from the main drainage pipe 2. The buffer tube 4 is close to the one end of the drainage person in charge 2 and is installed first flange 41, installs first filter screen 42 in the first flange 41, and first filter screen 42 is stainless steel. Buffer tube 4 can release the atmospheric pressure that high-rise building sewage let off the formation down fast to the header tank 1 in, prevent that the pipeline from receiving the atmospheric pressure inflation and breaking, effectively prevented the back towards of foul smell and sewage. The first filter 42 is disposed to prevent solid foreign matters in the sewage from entering the buffer tube 4 or the water collecting tank 1 to cause blockage when the sewage is discharged rapidly. The slope setting of buffer tube 4 can avoid the drainage to be responsible for 2 sewage entering buffer tube 4 when pressure is normal, reduces the erosion and corrosion of sewage to first flange 41 and first filter screen 42, has prolonged the life of first flange 41 and first filter screen 42.
Referring to fig. 3, the main drainage pipe 2 is further connected to a return pipe 5, and the return pipe 5 is located below the water collection tank 1 and is connected to the lowest horizontal position of the conical portion at the bottom of the water collection tank 1. One end of the return pipe 5 close to the drain pipe is provided with a second flange 51, a second filter screen 52 is arranged in the second flange 51, and the second filter screen 52 is also made of stainless steel. The return pipe 5 enables the water collecting tank 1 and the main drainage pipe 2 to be communicated in a circulating mode, so that the pressure generated by the water collecting tank 1 on the main drainage pipe 2 can be better buffered, and sewage entering the water collecting tank 1 from the buffer pipe 4 can be discharged into the main drainage pipe 2 from the return pipe 5. The arrangement of the second filter screen 52 can block solid foreign matters in the sewage entering the return pipe 5, and avoid the blockage of the return pipe 5. The conical arrangement of the water collecting tank 1 has a guiding function on the sewage entering the water collecting tank 1, so that the sewage can flow into the main drainage pipe 2 through the return pipe 5 more easily, and the sewage accumulated in the water collecting tank 1 is avoided.
The edge of the first filter screen 42 and the edge of the second filter screen 52 are wrapped with a sealing sleeve 6 respectively, and the sealing sleeve 6 is made of rubber and is sleeved on the circumferential edge of the first filter screen 42 and the circumferential edge of the second filter screen 52. The setting of seal cover 6 has guaranteed the leakproofness of filter screen with the flange butt department, prevents that sewage from oozing from the junction of filter screen and flange, and the material of rubber also can reduce the friction loss between filter screen and the flange, has prolonged the life of flange and filter screen.
The implementation principle of the embodiment is as follows: the one-way valve 31 is arranged to ensure that the sewage can only flow into the main drainage pipe 2 from the branch drainage pipe 3, thereby preventing the sewage and the odor from flowing back to the kitchen or the toilet to cause pollution. When the check valve 31 is out of order, the back flushing of sewage and odor can be prevented by closing the emergency valve 32. The arrangement of the buffer tube 4 and the return tube 5 enables the water collecting tank 1 to be circularly communicated with the main drainage pipe 2, so that air pressure formed by quickly discharging sewage of a high-rise building is released into the water collecting tank 1, the pipeline is prevented from being broken due to air pressure expansion, and odor and sewage are prevented from backflushing. The setting of filter screen can prevent that the solid foreign matter in the sewage from entering into header tank 1, avoids causing the jam. The conical arrangement at the bottom of the water collecting tank 1 plays a role in guiding sewage entering the water collecting tank 1, so that the sewage can flow into the main drainage pipe 2 through the return pipe 5 more easily, and the sewage is prevented from accumulating in the water collecting tank 1.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
