The triangle valve is divided into two types: "cold" and "hot" according to the difference between cold and heat (distinguished by blue and red signs). Most of the cooling and heating triangle valves in the same model of the same manufacturer are of the same material, and there is no essential difference. The main purpose of distinguishing between cold and warm Yes: hot and cold signs, mainly to distinguish which is hot water and which is cold water. Only some low-grade slow-opening triangle valves are rubber-ring spools. According to the opening method, the triangle valve can be divided into two types: "quick open" and "slow open". Quick opening refers to the rapid opening and closing of the valve by 90 degrees. Slow opening refers to 360 degrees of non-stop rotation of the angle valve handle to open and close the valve. It's basically a quick drive now. The size of the triangle valve: 3/8 refers to 3 points, which can be connected to a 3-point water pipe (generally used for a 3-point hard pipe on the inlet faucet). 1/2 refers to 4 points, which can be connected to 4 points of water pipes (generally used for faucets, toilets, water heaters with 4 points of water in and out, massage bathtubs, integral shower rooms and shower screens, and 1/2 for general households. ). 3/4 (straight valve) refers to a 6-point water pipe that can be connected to a 6-point water pipe (generally households rarely use a 6-point right-angle triangle valve, and a 6-point straight valve is generally used for the main water pipe and the water heater with 6-point inlet and outlet water. ).
