First appeared in sixteenth Century, with bronze casting, the main role is to control the water outlet switch and the size of the water flow. Early taps are spiral up and down, to the majority of the market is a ceramic spool of the faucet, spiral up and down the basic has been eliminated.
(1) [Stopcock]: stop or regulate the flow of water through the pipe
(2) [Swivel]: a rotary joint between the hose of the slurry pump and the rotary drill stem
(3) [Faucet; Bibcock; tap] Water: tap with lever and eccentric control switch
classification
1 according to the material to points, can be divided into SUS304 stainless steel, cast iron, stainless steel, brass, zinc alloy materials, such as water faucet, faucet and other types of polymer composite materials.
2. In terms of function can be divided into the washbasin, bathtub, shower, kitchen sink faucet and electric faucet (porcelain electric faucet), with the improvement of living standards, rapid heating faucet (porcelain electric faucet) more and more by consumers welcome, is expected to lead a new protagonist tap revolution.
3 according to the structure, and can be divided into single, double and triple type, such as several taps. In addition, there are single handle and dual handle. Single type can be connected with a cold water pipe and a hot water pipe; double type can be hot and cold at the same time then two channels, used for bathroom vanities and supply hot water kitchen vegetable washing basin faucet; triple type in addition to the two hot and cold water pipes, can also take a shower nozzle, mainly used in the bathtub faucet. The single handle water tap can regulate the temperature of the cold and hot water through a handle, and the handle of the two hands can respectively adjust the water temperature of the cold water pipe and the hot water pipe.
4 according to the way to open, can be divided into spiral type, wrench type, lift and induction type, etc.. Spiral handle is open, to rotate a circle; the wrench handle generally only need to rotate 90 degrees; carried Kai type handle only need to carry a can be out of the water; induction faucet as long as his hand under the faucet will automatic water. In addition, there is a delay off the faucet, turn off the switch, the water will be a few seconds to stop the flow, so that the dirty things on the faucet when the stick can also be washed clean.
5 according to the valve core to divide, can be divided into rubber core (slow open valve core), ceramic spool (fast open spool) and a few kinds of stainless steel spool. Affecting the quality of the most critical is the spool. The use of rubber core of the tap to the cast iron spiral open the tap, has basically been eliminated; Taocifaxin faucet is developed in recent years, better quality, more common; stainless steel spool is more suitable for poor water quality in the area.
5 water tap water purifier
For leading water purifier main water purification technology are the following: (1) activated carbon technology with activated carbon for leading water purifier main water purification materials, nano active filter adsorption ability better, in the saturated adsorption of water chlorine, heavy metals and pesticides have better filtering effect. (2) hollow fiber technology to hollow fiber membrane based water purification technology, can filter out the vast majority of pollutants in water, the need for regular replacement of filter. (3) ceramics and nano -KDF domestic large department products use is to micropore ceramic filter element and nano -KDF filter, to chlorine ball, alkali ball based water purification technology, the water flow is greater than the technology of hollow fiber water purifier, ceramic filter can again with a clean brush to use and to a certain service life, regular replacement of filters.
