Drainage embedded parts are an important part of the building drainage system, and their selection directly affects the performance and reliability of the drainage system. This article will explain how to choose the right drainage insert to ensure the proper operation of the drainage system. 1. Types of drainage embedded parts According to their functions and uses, drainage embedded parts are mainly divided into the following categories: 1Rainwater drainage embedded parts: mainly used to collect roof rainwater and introduce it into rainwater pipes to reduce the pressure on the urban drainage system. 2.Sewage drainage embedded parts: used to collect sewage from toilets, kitchens and other places, and introduce it into sewage pipelines to avoid sewage pollution to the environment. 3.Air Conditioning Drainage Embedded Parts: Used to collect air conditioning condensate and introduce it into the drainage pipe to avoid the impact of condensate leakage on the building structure. 4.Fire drainage embedded parts: used to collect the wastewater generated by fire fighting equipment such as fire elevators and fire pumps, and introduce it into the fire drainage system to ensure the normal operation of fire fighting equipment.
Second, the selection of drainage embedded parts in the selection of drainage embedded parts, the following factors need to be considered: 1Material: The material of the drainage embedded parts is generally made of cast iron, plastic and other materials. Cast iron material has the advantages of high strength and good corrosion resistance, but it is highPlastic materials have the advantages of being cheaper and easier to install, but they have poor corrosion resistance. The appropriate material should be selected according to the use environment and the discharge medium. 2.Size: The size of the drainage embedded parts should be selected according to the diameter of the connected drainage pipe and the on-site installation conditions. When choosing, you should ensure that the size of the drainage insert matches the drainage pipe, and consider reserving a certain amount of space to facilitate installation and maintenance. 3.Tightness: The tightness of the drainage insert is critical to the proper functioning of the drainage system. When choosing, you should choose a product with good sealing performance and ensure that the sealing ring will not be damaged or cause problems such as water leakage during installation. 4.Pressure resistance: For high-rise buildings or places with large water discharge, it is necessary to choose drainage embedded parts with strong pressure resistance. The pressure resistance is generally related to the material and structure, and the selection needs to be evaluated according to the actual situation. 5.Anti-corrosion ability: For the corrosive discharge medium, such as sewage, acid and alkali wastewater, etc., it is necessary to choose drainage embedded parts with anti-corrosion ability. Products made of cast iron generally have strong anti-corrosion ability, while products made of plastic materials are weaker. For use in corrosive environments, drain inserts with anti-corrosion coatings or corrosion-resistant materials should be selected. 6.Ease of installation: When choosing drainage embedded parts, it is also necessary to consider the ease of installation.
