【 Weak current College 】 indoor drainage-the second section of the drainage system commonly used equipment

This section describes common equipment of drainage systems have soil appliances, washing equipment, washing equipment, accessories and HES drainage snorkel, learn various drainage devices of different forms and use requirements, snorkel and its type. First, the stool and fecal slot 1 stool
The stool is sitting, squat type. Sitting stool by flushing can be divided into the hydraulic principle washout and siphon two, sit on stools will bring water bends (seal); squatting stools without water bends, design installation needs other configuration water bends.

2. poop chute
Often built in the densely populated or mobility.　　Second, the urinal urinal in the men's room, hanging, vertical and urinal troughs, three types of vertical urinal for standard and high buildings.　　3. washing utensils washing apparatus in General by the washbasin, washing tank, bathtubs and shower, etc.　　4. washing apparatus mainly sinks, laboratory sinks and sewage basins, etc. 5. Annex 1 water bends
Water bends type has the S-type and P-type, is passed a certain height of water (typically 50-100 mm), block drainage systems of toxic gas or insects into the rooms, the indoor environment and health.

2. check the mouth and sweeping mouth
Inspection openings and sweeping mouth's role is to facilitate dredging, drainage pipe and tube has set.
Check the port settings in vertical pipes, multi-layer or tall buildings within the drainage pipe one every two floors. Sweeping mouth General settings in horizontal pipe, horizontal pipe health apparatus attached to a large sweeping mouth should be set starting point.

3. floor drain
Floor drain drainage device used to belong to the exclusion of the ground water. 　　Floor drain general common floor drain, multi-channel leak, leak, water boxes, double-floor drain grate Cup and backflow floor drain, etc. 6. drainage ventilation tube 1. drainage ventilation tube system
① the drainage pipe out toxic gas emissions to meet hygiene requirements.
② snorkel to recharge the air inside the drainage pipe to reduce pressure fluctuations, prevent water damage.
③ by supplementing the fresh air, reduce the corrosion of metal pipes, extended service life.
④ set snorkel can increase the capacity of the drainage system.

2. drainage ventilation tube system type
Drainage snorkel system has reached the top snorkel, special ventilation stack, the main ventilation risers, Deputy ventilation risers, combined with snorkel, ring snorkel, apparatus snorkel and join snorkel, etc. type, are used in different locations. In addition, there is a new type of Suwito drainage pipe system, the floor of the mixer and the lowest layer on water, it is easy and the benefits of the project cost low.

3. set the conditions of the snorkel snorkel set conditional comment extension type top snorkel set in drainage piping or dissemination of harmful gases production waste water pipe when unconditional settings, you can set the inspiratory valve dedicated ventilation stack set in the drainage pipe drainage design flow over without special ventilation risers of the drainage pipe maximum drainage capacity dedicated ventilation tube diameter and the drainage pipe's diameter is the same as the main ventilation risers or Deputy ventilation riser set to building floors of horizontal drainage pipes with ring when the general use of snorkel in conditions more sophisticated architecture and high-level public buildings combined with snorkel with special ventilation risers or main ventilation risers, the need to set the connection drainage pipe and dedicated ventilation risers or main ventilation risers with snorkel snorkel set to ring: ① connect four and four more health apparatus and the distance is greater than the vertical tube 12m of horizontal drainage pipes; ② connect 6 and 6 above in the stool of horizontal pipes; ③ equipped with appliances vented drainage pipes in general use in conditions more sophisticated architecture and high-level public building apparatus snorkel set to health, quiet request high building sewage drainage system in the convergence snorkel set to not allow excessive stretching top snorkel or impossible to separate out the number of root set when roof reaching top snorkel tandem rear to outdoor convergence snorkel
