Double-seal transient negative pressure strong siphon closestool sewage drainage device

Abstract

The invention discloses a double-seal transient negative pressure strong siphon closestool sewage drainage device. The double-seal transient negative pressure strong siphon closestool sewage drainagedevice comprises a double-seal main body, an upper sealing opening, a strong washing valve main body, a tap water connector, a water tank, a water inlet rod main body, a drainage valve main body, a negative pressure pipe, a water pressure pipe, a brushing hole, a bed pan, a negative pressure bag main body, a sewage drainage opening, a drainage pipe, a drainage one-way valve, a lower sealing opening, a sewage drainage pipe air hole, a bottom drainage sealing line, a sewage drainage pipe middle, a bed pan water storage line, a light sealing ball and a sewage drainage pipe upper portion; the double-seal transient negative pressure strong siphon closestool sewage drainage device is mainly characterized in that the upper portion of the sewage drainage pipe upper portion is utilized, the double-seal main body is installed through the sewage drainage pipe air hole, when the negative pressure pipe makes certain negative pressure formed inside the double-seal main body and the sewage drainage pipe upper portion, part of water can pass through the sewage drainage pipe air hole to seal the light sealing ball and the upper sealing opening, so that the negative pressure pipe only achieves the effect of transient negative pressure, the sewage drainage pipe middle quickly forms negative pressure siphon, the replacing effect on sewage and dirt by later siphon force is not influenced, and thusthe effects of quick siphon, strong replacement and strong water saving are achieved.

Description

technical field [0001] The invention relates to a toilet blowdown system, in particular to a double-sealing valve main body installed above the upper part of the blowdown pipe through the vent hole of the blowdown pipe. Finally, part of the water will seal the lightweight sealing ball and the upper sealing port through the vent of the sewage pipe, so that the negative pressure pipe only plays the role of instantaneous negative pressure, so as to realize the rapid formation of negative pressure siphon in the middle of the sewage pipe without affecting the later siphon It is a double-sealed instant negative pressure powerful siphon toilet sewage device that can effectively replace dirty water and dirt. Background technique [0002] Now, the industry standards for sanitary ceramics are becoming more and more refined and strict. There is basically no problem in controlling the water consumption of toilets produced by various manufacturers within the secondary water-saving standa...

Problems solved by technology

The problem is that if the conveying distance is 18 meters, it will not be able to pass the test. After a long time, it will definitely cause blockage of the sewage pipe; the negative pressure bag fast siphon patented technology introduced from Canada, from the surface, the water in the bedpan is quickly sucked into the sewage pipe. However, due to the long-term continuous effect of negative pressure during flushing, the upper bend of the sewage pipe first becomes an empty water area, the siphon toilet does not even have a siphon, and the downward bend of the sewage pipe always has dirt that is not completely replaced. This design is based on the principle The replacement process of the negative pressure siphon was not clarified
