At present, China industry resistant, corrosion-resistant valve on the pipe installation using a metal valve sealing surface, using this valve Although a hundred years of history, but there are many problems, has been plagued condition owners. Meanwhile although after the construction and improvement of the material, but the metal material due to restrictions of their own conditions, increasingly unable to meet high wear, corrosion and other needs of poor working conditions, the practical needs of forcing us from materials, design and manufacturing processes and other aspects of the implement thorough and effective innovation. Advantage of its tensile strength ceramic materials, compressive strength, elastic modulus, hardness and other aspects stand out, hop upstart gas patio heater valve materials for the 21st century, new ceramic valves emerged, celebrates its spring.
Ceramic valve structure using high-tech new ceramic materials valve sealing parts and wearing parts, valve products increased wear resistance, corrosion resistance and sealing, greatly extending the life of the valve.
2, different technology
There are many manufacturers use the valve is filled with adhesive bonding. Adhesive bonding process is simple, high yield, but the valve into operation ceramic ring and steel combined with very unstable. As the steel parts, adhesives, linear expansion coefficient of the ceramic is not the same as when the temperature changes or the sealing surface pressure is too large ceramic ring easy to loose, cracked or even fall off. Because no standard ceramic ring heat treatment and aging treatment, sometimes cracking the gas cooker safety valve will occur in the warehouse during the placement of the ceramic ring.
