The triangular valve is divided into hot and cold:
"Cold" and "Hot" (different from blue and red signs) The same type of cold and warm triangular valve in the same manufacturer has the same material with no essential difference. The main purpose of distinguishing between cold and warm is: hot and cold signs, mainly It is to distinguish which is hot water and which is cold water. Only some low-end slow-opening triangle valves are rubber ring spools, and the rubber ring material can not withstand 90 degrees of hot water, which needs to be divided into hot and cold.
The triangular valve is divided according to the opening method:
"Quick open" and "slow open". Quick opening means turning the valve on and off 90 degrees quickly. Slow opening refers to the 360 ​​degree non-stop rotary angle valve handle to open and close the valve. Basically, it is all about using quick opening.
Triangle valve size:
3/8 means 3 points, which can be connected to a water pipe of 3 points (usually used for 3 points on the faucet).
1/2 means 4 points, can be connected to 4 points of water pipes (usually used for faucets, toilets, 4 points of water and water heaters, jacuzzi, whole shower room and shower screen for table top water, general household use 1/2 )
3/4 (straight valve) refers to 6 points, can be connected to 6 points of water pipes (usually, households rarely use 6-point right-angled triangular valves, while household water pipes and 6-point water inlet and outlet water heaters generally use 6-point straight valves. ).
The triangular valve can be divided according to the valve core:
Ball valve core, ceramic valve core, ABS (engineering plastic) valve core, alloy valve core, rubber rotary valve core.
1. Ball valve core: The advantage of the spherical valve core is that the diameter is larger than the ceramic valve core, it does not reduce the water pressure and flow rate, and the operation is convenient (rotary 90 degrees can be fully open / fully closed), STH valve core is chrome plated of. The advantages of chrome plating are high hardness and wear resistance, long service life; avoiding the production of patina. 2. ABS (Engineering Plastics): Plastic valve cores are low in cost and quality is not guaranteed.
3. Ceramic valve core: The advantage of the ceramic valve core is that the switch feels smooth and light. Applicable to the family, long service life and high cost. A ceramic spool is recommended.
4. Rubber rotary spool: It has now been eliminated because opening and closing is very time-consuming and labor-intensive, and angle valves of this material are rarely used in the home.
The triangular valve is divided according to the material of the casing:
Brass, alloy, iron, plastic.
Brass: easy to process, strong plasticity, hardness, strong resistance to bending and torsion.
Alloy: low cost, the disadvantage is that the bending resistance is low and the surface is easy to oxidize.
Iron: It is easy to rust and pollute the water source. It is not recommended in today's society where environmental protection and low carbon are used.
Plastics: Low cost and not easy to use in the extremely cold north.
