2019-07-03 1085

Speaking of faucets, I believe we are all families with them Every morning when we brush our tea or wash our face, we come into contact with them In the process of home decoration, we also choose high quality faucets, which are related to the water saving performance of faucets, such as pipe thread accuracy, acid salt spray experience, and flow rate Toda y, let&# 039; Learn about the structure of faucets

1. A faucet is composed of a main body, valve core, handle, water filter noise, water outlet, device components, etc

2. The pipe thread is the pipe thread that connects the faucet to the water pipe interface Usually, the accuracy of pipe threads not only affects the device, but also causes water pipe leakage due to poor thread accuracy in the future use of the device, which can cause loss to the user

3. The faucet is divided into single and double faucet A single faucet, as the name suggests, requires only one inlet pipe and only one water pipe, which can be either hot or cold, and is generally used in related ordinal areas; The difference between a dual faucet and a single faucet is that it has two water inlets, which can control the water outlet through two handles and adjust the water temperature through the handles

4. The valve cores of faucets are classified by material, including rubber valve cores, axial rolling valve cores, ceramic valve cores, and stainless steel ball valve cores; According to the functional classification, there are several types of manual valve cores, constant temperature valve cores, magnetic induction valve cores, and so on. The faults that use rubber cores are mostly spiral open cast iron faults, which have been basically phased out now; Ceramic valve core is a new generation of valve core material with good sealing performance, stable physical performance, and long service life Calculated based on opening and closing 30 times a day, it can be used for more than 20 years without drilling
