When the purchase of visual valves, the surface should be no blisters; plating surface should be uniform, should pay attention to whether there is peeling, cracking, scorching, exposed, flaking, dark spots and obvious pitting and other defects; spray surface tissue should be fine, smooth Uniform, no sagging, exposed defects. Civil valves commonly used in ordinary households commonly used gate valve, ball valve, triangular valve and other forms, usually iron or copper. As the mechanical properties of copper alloy, with less rust, corrosion resistance advantages, so the copper valve has gradually replaced the iron valve. Triangle valve surface are basically used electroplating, its role is not only to control the flow of pipeline media, but also play a decorative role. Triangle valve is generally connected to the pipe and water hose for the faucet, toilet water supply, there are connecting pipes and water hoses for water heater. Gate valve is basically used for pipe and water meter connection. Ball valve for the connection of pipes and water heaters. Because the ball valve opening and closing than the convenience of the valve, the current connection of the pipe and the meter most of the ball valve. Civil valves should be selected: According to the different requirements of users choose different types of civilian valves: 1. Optional visual valve, the surface should be no blisters; plating surface should be uniform, should pay attention to whether there is peeling, cracking, scorching , Exposed bottom, spalling, dark spots and obvious pitting and other defects; Spray the surface tissue should be fine, smooth and uniform, without sagging, exposed defects. The above defects will directly affect the service life of the valve. 2. Valve pipe thread is connected with the pipe, the purchase of visual inspection of the surface of the thread has no dents, broken teeth and other obvious defects, it is important to note that the effective length of the pipe thread and the screw connection will affect the reliability of the seal Sexuality, purchase should pay attention to the effective length of pipe thread. General DN15 cylindrical thread effective length of about 10mm. 3. Gate valve, ball valve is generally marked on the valve body or handle nominal pressure, optional according to their own needs. 4. Replace the existing gate valve or ball valve, we must find out the length of its structure, so as not to buy after the installation. 5. Triangle valve pipe thread with internal and external thread two, according to the need to buy; also note that there is currently on the market part of the triangle valve made of zinc alloy, the valve price is lower than the average product, but Corrosive and cause rupture. As far as possible in the regular building materials stores, shopping malls, so product quality can guarantee.
