Description

Technical Field

[0002] With social development and technological progress, people's living standards have gradually improved. In building construction, the drainage system of the bathroom is particularly important. For example, in the invention patent application entitled "An L-shaped Bathroom Micro-lowering Slab Same-floor Drainage System" (publication number CN112962727A), a micro-lowering slab same-floor drainage system is designed. It uses flat pipes as drainage fittings, slightly lowering the floor height to meet the conditions for same-floor drainage. It is adaptable to various installation scenarios, occupies little floor space, and is highly practical. In the event of a fire, it can prevent the fire from spreading to other floors. However, during the use of the drainage system, negative pressure is easily generated in the drain pipe. Under the presence of negative pressure, the water seal of the drain pipe is damaged, causing the odor from the drain pipe to overflow into the bathroom, which cannot meet the increasingly higher environmental quality requirements of modern urban buildings.

[0013] Beneficial effects

[0014] This invention provides a fully closed-loop sanitary and safe drainage system for building sewer pipes. It solves the technical problem that negative pressure easily forms within the sewer pipes during operation, disrupting the water seal and causing odors to leak into the bathroom. The invention installs a positive and negative pressure resistant device within the horizontal branch pipe drainage assembly. This device, through a pressure-conducting membrane, a transmission connecting rod, and a pressure conductor, ensures that when the pressure at the upper end of the water seal is greater than the lower end, the pressure membrane presses against the pressure conductor, causing it to move downwards. This pressure conductor then pushes the transmission connecting rod, which in turn holds the support rod in place, preventing the support rod from rotating and pushing the balance shaft bidirectional power valve plate. This, in turn, prevents the balance shaft bidirectional power valve plate from opening the opening and closing valve plate, effectively preventing odors from the riser and horizontal branch pipe drainage assemblies from emanating from sinks, washing machines, toilets, same-floor inspection drains, and sealed floor drains.

The other end of the bent water seal body 62 is connected to a lower branch pipe 65, which is connected to the sixth water pipe 19.

[0027] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0028] Example: As shown in the attached drawings of the instruction manual, during use, water from different floors is introduced into the vortex generator 7 through the upper inner spiral pipe 5 and discharged through the lower inner spiral pipe 6. Wastewater from the toilet 3 is introduced into the vortex generator 7 through the first water pipe 8 and discharged through the lower inner spiral pipe 6. Wastewater from the washbasin flows through the trap 20 and the sixth water pipe 19 to the second oblique tee 17. Water from the sealed floor drain 18 flows into the second oblique tee 17 and flows through the fifth water pipe 16, elbow 15 and fourth water pipe 14 into the first oblique tee 10. At this time, the water flows into the second water pipe 9 and into the vortex generator 7, and is discharged through the lower inner spiral pipe 6. Wastewater from the washing machine 2 flows through the connector 12, the third water pipe 11 and the same-floor maintenance floor drain 13 into the first oblique tee 10, flows into the second water pipe 9 through the first oblique tee 10, and flows into the vortex generator 7 and is discharged through the lower inner spiral pipe 6.

[0029] When negative pressure occurs in the riser drainage pipe assembly and the horizontal branch drainage pipe assembly, a pressure difference exists between the upper and lower ends of the pressure transmission membrane 26 (the pressure transmission membrane is made of high-elastic rubber material). The pressure at the upper end of the pressure transmission membrane 26 is greater than the pressure at the lower end. The pressure generated by the pressure difference acts on the pressure conductor 22, which generates downward pressure. This causes the lower end of the transmission connecting rod 27 to act on the upper end of the support rod 30 of the balance shaft bidirectional power valve plate 23. Since the arc surface at the lower end of the transmission connecting rod 27 contacts the arc surface at the upper end of the support rod 30, a resistance torque is generated through the rotating shaft 35 of the balance shaft bidirectional power valve plate 23 to prevent the opening and closing valve plate 31 from opening. When the balance shaft bidirectional power valve plate 23 is under negative pressure in the drainage pipe, the opening and closing valve plate 31... There is also a pressure difference between its upper and lower ends, with the upper pressure being greater than the lower pressure, thus generating downward pressure and torque that causes the valve plate 31 to open. When the resistance torque of the valve plate 31 closing is greater than or equal to its opening torque, the balance shaft bidirectional power valve plate 23 remains closed and the valve plate 31 is pressed tightly against the sealing ring of the main body 21. The second fixed magnetic core 37 and the second moving magnetic core 39 attract each other, preventing negative pressure from passing through. This can prevent the water seal from being destroyed by the negative pressure in the drain pipe assembly and the horizontal branch pipe assembly, and prevent the odor in the drain pipe assembly and the horizontal branch pipe assembly from overflowing through the same-floor maintenance drain 13, the sealed drain 18 and the washbasin, thus preventing the washing machine 2 from being contaminated by odor.

[0030] When the riser drainage pipeline assembly and the horizontal branch drainage pipeline assembly generate positive pressure or when sewage overflows, the lower end of the opening and closing valve plate 31 of the balance shaft bidirectional power valve plate 23 is closed under pressure (based on the principle of a check valve).

[0031] When drainage occurs, the water pressure acting on the pressure transmission membrane 26 is less than the water pressure on the valve plate 31. Therefore, the torque generated to prevent the valve plate 31 from opening is less than the torque to open the valve plate 31. The balance shaft bidirectional power valve plate 23 opens to drain. When drainage stops, the balance shaft bidirectional power valve plate 23 generates a torque to close the valve plate 31 under the attraction of the second fixed magnetic core 37 and the second moving magnetic core 39 and the repulsion of the first fixed magnetic core 36 and the first moving magnetic core 38. The valve plate 31 closes, blocking the water seal and usable space in the lower riser drainage pipeline assembly and the horizontal branch drainage pipeline assembly.
