Floor drain is a sanitary device that excludes indoor area water. Its main task is to eliminate indoor floor water and prevent harmful gases in the drainage system from entering the room. People have three basic requirements for it: First, they have a certain drainage capacity. Second, have a certain depth of water seal, that is more than 5 cm. Third, have a certain ability to pollute self-cleaning. However, the floor drain has two special features: 1 It excludes surface water, and the water quality is sometimes worse than any other equipment. There are many solids and fibers, and it is easy to deposit in the trap; 2 The adjacent two drainage The maximum time distance is longer than other utensils, so that the sediment is accumulated and cannot be cleared by the next drainage. Therefore, the floor drain generally does not have a trap, and a water seal structure is made on the floor drain product itself to facilitate removal of the deposit. Drainage site trap water body is very easy to form a new odor source due to deposition of black hair odor, it is recommended to promote the need for users to seal the water rotation, in order to ensure that the water seal water is fresh and disinfected. Avoid mosquito breeding. The need for floor drain installation and the use of common sense First, the drainage capacity is the minimum requirement for floor drain, as it is originally used to exclude the surface of the waste water appliances. The need for floor drain installation is also reflected in its use as an emergency leak after the burst water pipe or faucet closure fails to prevent the flood damage from expanding after the burst water pipe or faucet closure fails. Installation and use of common sense: floor drains should be slightly lower than the ground. The floor must be sloped and drained to the floor. When the broom sweeps to the floor and drains with difficulty, it is too late for repentance. It is not a place where water is often generated. Floor drains should not be installed. The location of the design floor drain should avoid the location where the kitchen equipment may be installed. It is forbidden to remove the location of the original floor drain of the rough house where the water seal and the deodorizing floor drain are removed during the renovation. Since this is only two methods such as moving: First, laying pipes on the rough floor. Calculate according to the current 50 type with the smallest drain diameter. Leveling the ground to a minimum requires laying a layer of concrete 7 cm thick. If you want to ensure that the leak seal is qualified more than 5 cm. The height of the sloping floor and pipeline slope will be used to pay for a 15 cm thick concrete cushion for this random alteration. The conservative estimation cost is more than 300 yuan. It is only for modification and installation, and may not meet the required floor drain. It is not advisable to spread resources and increase the weight of the building. The reason for moving the floor drain is often due to the installation of kitchen and bathroom equipment. It is recommended that when installing kitchen and bathroom equipment, it is recommended to avoid in-situ leakage or to install in the same drainage system where the caisson-type drainage pipeline can be modified. The second is to dig the fascia to the downstairs, but it must be re-waterproof. The problem is that when the property downstairs is not your property or has been decorated, it is often difficult to implement. This is also the reason why the trap with a checkpoint cannot exert its effect during obstruction. Second, the depth of the water seal, which we may not understand, first of all we have to understand what is the water seal it? Water seal is a water storage device that is used to block odor escape. What is the depth of water seal? It refers to the vertical interval between the highest water surface of the drain trap and the lower port of the water seal. Regarding this vertical interval or the depth of the water seal, the national water supply and drainage is mandatory: the depth of the water seal of the drain trap and the floor drain. Not less than Installation and use of common sense: we all believe that as long as there is water, it is also an important misunderstanding of drainage pipe fittings and floor drain manufacturers. A large number of water seals are used to meet the standard of floor drains and traps. The sewer returns smell to the social problem. Why do we have to 5 centimeters? Its scientific nature is there? We should understand that the life sewer pipeline is a three-phase review of water, gas and solids. The peak flow even covers the whole pipe section. The positive and negative pressures generated at this time can easily destroy the water seal and then evaporate naturally. However, if the water seal depth is more than 5 cm, the water seal can be basically avoided and the health of people can be guaranteed. . Remember 5 centimeters!
