When you purchase your visual valve, the surface should have no trachoma; plating the surface should be shiny uniform, to watch for peeling, cracking, burning, Lo the end of peeling, dark spots and obvious defects such as pits; spraying the surface of organizations should be detailed, smooth and uniform, not a stream linked to defects such as exposed at the end.
Civil valves commonly used in the current average family generally have gate valve, ball valve, triangle valve and other forms, usually iron or copper.
As the mechanical properties of copper alloys is good, with easy to rust, corrosion resistance strong advantages, it has gradually replaced the valve copper valve steel. Triangle valve basically have adopted the surface plating, and its role not only to control the flow of media channels, but also play a decorative role. Triangle valve normally connecting pipes and water hoses for Tap, Toilet water use, there are connecting pipes and water hoses for the water heater.
Gate the basic connections for the pipes and water meters.
Valve is used to connect pipes and water heaters.
As the ball valve open and close easily than the current pipeline and meter connections are also most of the use of ball valves.
Civil valves buy:
Should be based on the user's different requirements of different types of commercial valve selection:
1. When you purchase your visual valve, the surface should have no trachoma; plating the surface should be shiny uniform, to watch for peeling, cracking, burning, Lo the end of peeling, dark spots and obvious defects such as pits; spraying the surface of the Organization should dense, smooth and uniform, not a stream linked to defects such as exposed at the end. These deficiencies will directly affect the life of the valve.
2. Valve with the pipe connection pipe thread, and in choosing whether or dent the surface when the visual thread, broken teeth and other obvious defects, with particular attention to the pipe thread to connect pieces of rotating together with the effective length will affect the seal of the reliability, should pay attention to when purchasing the effective length of the pipe thread. General DN15 effective length of cylindrical pipe thread in the 10mm or so.
3. Gate valve, ball valve, or in general in their marked nominal pressure on the handle to purchase when the need to choose according to their own.
4. The replacement of existing gate valve or ball valve, it is necessary to ascertain the length of its structure so that can not be installed after purchase.
5. Triangular valves are female pipe thread and external thread two kinds, based on the need to purchase; would also like to note that currently on the market some of the triangular zinc alloy valves, the valve price is lower than the average product, But easy to fracture caused by corrosion.
Should be in a regular building materials stores, supermarkets, shopping, so that can better guarantee product quality. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve ball valve V Type Ball Valve
