According to the distinction between cold and hot, the triangle valve includes:
Two kinds of "cold" and "hot" (distinguished by blue and red signs). Most of the materials of the heating and cooling triangle valves of the same manufacturer and the same model are the same, and there is no essential difference. It is to distinguish which is hot water and which is cold water. Only partly low
The slow-opening triangle valve of the gear is a rubber ring spool. The rubber ring material cannot withstand 90 degrees of hot water and needs to be divided into hot and cold.
According to the opening method, the triangle valve is divided into:
There are two types of "Quick Open" and "Slow Open". Quick opening refers to the rapid opening and closing of the valve at 90 degrees. Slow opening refers to the ability to rotate the angle valve handle 360 degrees non-stop
Open and close the valve. Now basically use quick opening.
The size of the triangle valve:
3/8 refers to 3 points, which can be connected to a 3-point water pipe (usually used for a 3-point hard pipe on the water inlet).
1/2 refers to 4 points, which can be connected to 4 points of water pipes (usually used for faucets, toilets, 4 points of water in and out of water heaters, jacuzzi
, The overall shower room and shower screen, generally used by households 1/2)
3/4 (straight valve) refers to 6 points, which can be connected to 6 points of water pipes (generally, the 6 points right angle triangle valve is rarely used in households, and the main water pipe is 6 points
Water heaters with water inlet and outlet generally use 6-point straight valves).
According to the spool of the triangle valve, it can be divided into:
Spherical valve core, ceramic valve core, ABS (engineering plastic) valve core, alloy valve core, rubber rotary valve core.
1. Spherical spool: The advantage of the spherical spool is that its caliber is larger than that of the ceramic spool, it will not reduce the water pressure and flow, and it is easy to operate (rotate 90 degrees)
It can be fully open/closed), the spool of STH is chrome-plated. The advantages of chrome plating are high hardness, wear resistance and long service life; avoiding patina. 2. ABS (
Engineering plastics): The cost of plastic valve cores is low, and the quality is not guaranteed.
3. Ceramic valve core: The advantage of ceramic valve core is that the switch feels smooth and light. It is suitable for families with long service life and relatively high cost. It is recommended to use a ceramic valve core.
4. Rubber rotary valve core: It has been eliminated now, because it takes time and effort to open and close, and this kind of material is rarely used in households at present
Angle valve.
