Angle valve, because the pipeline is in the shape of a 90-degree corner at the angle valve, it is also called an angle valve and a angled water valve.
Angle valve function:
Connect the internal and external water outlets; when the water pressure is too high, it can be adjusted to close on the triangle valve; it acts as a switch, if the faucet leaks, etc., the triangle valve can be turned off, and there is no need to close the main valve in the home; beautiful and generous . Generally, it is an essential plumbing accessory for new house decoration.
Types of AngleValves
According to hot and cold distinction:
There are two types of "cold" and "hot" (distinguished by blue and red signs). The material of the heating and cooling triangle valves in the same model of the same manufacturer is the same, and there is no essential difference. The main purpose of distinguishing between heating and cooling is: the sign of cold and heat, mainly to distinguish which is hot water and which is cold water. Only some low-grade slow-opening triangular valves are rubber-ring spools.
Distinguish according to the opening method:
There are two types of "fast opening" and "slow opening". Quick opening refers to the rapid opening and closing of the valve by 90 degrees. Slow opening means that the handle of the angle valve can be rotated 360 degrees to open and close the valve. It's basically a quick drive now.
According to the valve core:
1. Spherical spool: The advantage of the spherical spool is that the diameter of the spool is larger than that of the ceramic spool, which will not reduce the water pressure and flow rate, and is easy to operate (fully open/close by rotating 90 degrees). The STH spool is chrome-plated of. The advantages of chrome plating are high hardness, wear resistance and long service life; avoid patina.
2. ABS (engineering plastic): The cost of plastic valve core 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, has a long service life and a relatively high cost. Ceramic spools are recommended.
4. Rubber rotary valve core: It has been eliminated now, because it is very time-consuming and laborious to open and close. At present, households rarely use angle valves of this material.
The triangular valve is divided according to the shell material:
Brass: easy to process, strong plasticity, hardness, and strong bending and torsion resistance.
Alloy: low cost, the disadvantage is low bending and torsion resistance, and the surface is easy to oxidize.
Iron: easy to rust and pollute water sources. It is not recommended to use in today's environment-friendly and low-carbon society.
Plastic: low cost, not easy to use in the extremely cold north.
