| The valve core is one of the important parts of the control unit in the water faucet, valve and other fluid system. Spool is the use of its movement to achieve the direction of control, pressure control or flow control of the basic functions of the valve parts. Any leading switch control to a spool, for water, the quality of the spool is an important basis for the water quality assessment, it can be said the most critical impact on water quality is the spool. Common faucet valve core has a steel ball valve core and a ceramic valve core. Ball valve core has a very good anti pressure capacity, but the disadvantage is that the sealing effect of the rubber sealing ring is easy to wear and tear, will soon be aging. Compared with the ball valve, ceramic valve core more wear-resisting and heat-resisting, also ceramic valve core has good sealing performance, it can achieve a high frequency of resistance to opening, not because of the valve wear and tear caused by tap drip. The use of ceramic valve core faucet, feel more comfortable, smooth, and open, close quickly. Because the valve core is in the inner of the water faucet, the consumer can not see the valve core in the purchase, but the consumer can simply judge the quality of the valve core according to the handle when the handle is rotated. Generally speaking, the consumer, the lower, left and right rotation handle, if the feeling of light, no block, it is better to explain the spool. The common valve core has three kinds: stainless steel ball valve, ceramic piece valve core and shaft rolling type valve core. The common characteristics of these three types of valve core are integral, and the whole core shaft is integrated, and the maintenance and the replacement are easy to be installed. The rotary valve core of the water tap has the advantages that the handle is rotated smoothly, the operation is easy and simple, and the handle is comfortable and relaxed. But the spool spool spool as old-fashioned, has been gradually to meet the needs of the crowd for the spool, so will gradually be eliminated by the market. Ceramic valve core faucet: comparable to diamond, leak and deformation of ceramic materials is very small, and the metal compared with higher binding strength. Generally composed of small ceramic crystal ionic radius, and ion price high, coordination number, these properties determines the ceramic material tensile strength, compressive strength, elastic modulus, hardness is very high. However, the "brittle" and difficult to process of the ceramic itself limits its application range. Over the last decade, due to martensitic transformation toughening technology composite material science and technology and nano ceramic concept of development and progress, has made ceramics "brittle" has been greatly improved, its toughness and strength has been greatly improved, application scope also in continuous expansion, such as applications in the faucet spool by greatly welcomed. Ceramic spool because of affordable, less water pollution, good wear resistance, good sealing performance, while the "brittle" of the improvement, so that the ceramic valve is widely used. In general, the ceramic valve core to a good sealing effect, due to foreign technical strength is relatively strong, some imported ceramic chip, sealing performance of relatively good, stable physical properties wear and long service life. Currently on the market most of the leading manufacturers of well-known brand sanitary ware has been mostly used ceramic valve. Stainless steel faucet valve is currently has a leading high tech valve, a number of high-end bathroom brands are used in laser processing technology of irregular seven ball valve, as the latest water valve. The industry also believes that the spool is more suitable for poor water quality areas, because it is not affected by the impact of impurities in the water, it will not shorten the service life. And the steel ball valve core of the handle in the area of regulating water temperature has a larger angle, can accurately control the water temperature, to ensure the rapid and accurate flow of hot water, to save energy efficiency. However, the production cost of stainless steel ball valve core is higher than other types of valve core, while the production of processing technology requires more fine, suitable for the water environment in poor areas of application. Currently on the market there are some brands of products is the use of stainless steel ball valve. |
