Commonly used plumbing babies at home generally have (brass or iron) gate valves, ball valves, triangle valves and other forms.
Because of the good mechanical properties of copper alloy, it has the advantages of not being easy to rust and strong corrosion resistance, so the copper water heater has greatly reduced the iron water heater. The flow rate can also play a role. Generally, connection pipes and water inlet advantages are used for faucets and toilets, and there are also general connection and connection pipe water inlet advantages for water heaters.

2. Plumbing and gas pipe threads are connected to the pipeline. Visually inspect the surface of the thread for obvious defects such as dents and cracks. Pay special attention to the effective length of the pipe thread and the component that will affect the sealing effect. General DN15 The effective length of time pipe thread is about 10mm.

3. Gate valves and ball valves are generally marked with a nominal pressure on their valve body or handle, and the time can be selected according to their needs.

4. When the gate valve or gate valve fails, find out the length of its structure and install it after playing games.

5. The pipe thread of the triangle valve has internal thread and external thread. It needs to be based on needs; it should be noted that there are some triangle valves made of zinc alloy on the market.
