中国各行业普遍使用的阀门为金属阀门,金属阀门的使用已有上百年的历史,虽然金属阀门经过结构及材料的改进,但受金属材料属性的限制,不能适应越来越高磨损、强腐蚀等恶劣工况的需求,主要体现在使用寿命短,泄露严重大大影响了系统运行的稳定性。传统的金属阀门急需从材料、设计及制造工艺等方面的彻底革新。
将陶瓷材料应用于工业阀门是一项大胆和有益的创新。
陶瓷材料变形量很小,比金属具有高得多的结合强度,一般情况下组成陶瓷材料的晶体离子半径小,而且离子电价高,配位数大,这些性质决定了陶瓷材料的抗拉强度、抗压强度、弹性模量、硬度等都非常高。然而陶瓷本身的“脆”及难加工限制了它的应用范围,近十几年来,由于马氏体相变增韧技术、复合材科技术及纳米陶瓷概念的发展及进步,已使陶瓷的“脆性”得到了大大改进,其韧性和强度得到了极大的提高,应用范围不断扩展。
近年来,新型陶瓷材料在石油、化工、机械等领域的应用非常活跃,利用陶瓷的耐磨性、耐腐性制作耐磨耐腐零件部代替金属材料,是近几年来高技术材料市场的重要发展方向之一。
产品性能特点: ★、所有与介质接触的部分均为结构陶瓷材料,其化学稳定性及硬度极高(洛氏硬度HRC90),仅次于金刚石。因此,
本阀具有极高的耐磨损、耐腐蚀、耐冲蚀性能,且隔热性好、热膨胀小。
★、球体采用先进研磨设备及工艺制造,球圆度精度高,表面质量好,与阀座对研后,利用Zr02陶瓷的自滑润性,可取得很好的密封性能。
★、彻底改变了金属硬密封球阀易泄露、扭矩大、密封面不耐腐蚀的缺点。
★、陶瓷良好的耐磨性,让本阀经久耐用,可靠性极高.使用寿命长,是钛合金阀和蒙乃尔阀的2-4倍。
★、用于高硬度的颗粒介质,或有软颗粒但又有腐蚀的介质中,本阀门具有无可比拟的{jd1}优势,也是目前{wy}合适此类介质的阀门。
陶瓷阀门的社会经济效益:
1.陶瓷阀采用高技术新型陶瓷结构材料制作阀门的密封部件和易损部件,提高了阀门产品的耐磨性、防腐性及密封性,大大延长了阀门的使用寿命。
2.陶瓷阀门的使用可以大大降低阀门的维修更换次数,提高配套设备运行系统的安全性、稳定性,节约设备修理费用。
3.陶瓷阀门的使用能提高工业管路系统的密封性,能{zd0}限度的减小泄露,从而保护环境。
4.制造陶瓷的原料广泛,成本低廉,用铝、碳、硅等普通无素就能制造出性能优越的陶瓷材料,可以节约大量金属材料和稀有的矿产资源。
耐磨陶瓷阀门主要应用于电力、石油、化工、冶金、采矿、污水处理等工业领域,尤其是面对高磨损、强腐蚀、高温、高压等恶劣工况,陶瓷阀更显示出它{zy1}的性能。陶瓷阀门能满足高磨损、强腐蚀的使用环境,尤其突出的特点是超长的使用寿命,陶瓷阀门的性能价格比远远优于其它同类金属阀门。随着科学技术的不断发展和进步,陶瓷材料从配方、成型、加工及装配工艺等各方面的技术更加趋于成熟和完备,陶瓷阀门以其优异的性能越来得到阀门行业人士的认同。利用制造陶瓷阀门的成功经验还可以推广应用于更广泛的工程领域。
※太阳能多晶硅专用阀(用于:气体输送硅粉)
在硅粉的输送中,球容易被硅粉包裹,频繁开启容易破坏金属密封,导致泄露等问题的出现,硅粉由于硬度高的原因,一般的球阀使用寿命非常短。
金泰美林公司针对这种情况,专门研究开发出适用的硅粉输送专用陶瓷阀,利用结构陶瓷的强耐腐蚀性,以及锆合金的高耐腐材料,使新阀门的寿命高于原阀门6倍之多,给太阳能多晶硅硅粉输送的设备管理带来了一个振奋人心的好消息!
性能特点: ★、所有与介质接触的部分均为结构陶瓷材料,其化学稳定性及硬度极高(洛氏硬度HRC90),仅次于金刚石。因此,

Commonly used in various industries in China valve metal valve,
metal valve used has a century of history, the metal valve through
the structure and material improvements, subject to the restriction
properties of metal materials, can not meet the increasingly high
wear, corrosion and other harsh conditions strong demand, mainly in
short service life, greatly affected the disclosure of a serious
system stability. Traditional metal valves needed from materials,
design and manufacturing processes, etc. overhaul. Ceramic
materials for industrial valves is a bold and useful innovation.
Deformation of ceramic materials is very small, much higher than
the metal with a combination of strength, generally composed of
ceramic materials crystal ionic radius, and ion price high, a large
coordination number, these properties determine the tensile
strength of ceramic materials , compressive strength, elastic
modulus, hardness and so very high.
Ceramic itself, however, the "brittle" and difficult to machine
limits its scope of application of the last decade, due to
martensitic transformation toughening technology, composite
materials and nano-ceramic Branch Technical development of the
concept and progress has been made ceramics " brittle, "has been
greatly improved, its toughness and strength has been greatly
improved, ever-expanding range of applications. In recent years,
new ceramic materials in petroleum, chemical, mechanical, and other
fields is very active, using ceramic wear resistance, corrosion
resistance and wear-resistant corrosion-resistant parts made of
metal materials to replace the Department, is an important market
in recent years high-tech materials development directions. Product
Features: ★, all parts are in contact with the media structure of
ceramic materials, their chemical stability and high hardness
(Rockwell hardness of HRC90), second only to diamond. Therefore,
The valve has a very high resistance to abrasion, corrosion and
erosion performance, and good heat insulation, small thermal
expansion. ★, ball grinding equipment and processes using advanced
manufacturing, high precision ball roundness, surface quality, and
the seat of the study, the use of self-lubrication of Zr02 ceramics
can be achieved very good sealing performance. ★, completely
changed the metal seal valve easy to leak, torque, sealing surface
corrosion of the shortcomings of impatience. ★, ceramics good
abrasion resistance, so that the valve durability, high
reliability. Long life, is a titanium valves and Monel valve 2-4
times. ★, granular media for high hardness, or soft particles, but
there are corrosion medium, the valve is absolutely unmatched
advantage, is the only appropriate medium for such valves. Ceramic
Valves social and economic benefits: 1. Ceramic valve
structure using high-tech new ceramic materials and
vulnerable parts of the valve sealing components, valve products
increased wear resistance, corrosion protection and sealing,
greatly extended the life of the valve. 2. Ceramic valve can
greatly reduce the use of replacement valve repair times, improve
equipment operation supporting system security, stability, saving
equipment repair costs. 3. Ceramic valves can increase the
tightness of industrial piping systems, can reduce the maximum
disclosure to protect the environment. 4. Manufacture a wide range
of raw materials ceramic, low cost, aluminum, carbon, silicon and
other common factors can not create superior performance ceramic
materials, can save a lot of metal materials and scarce mineral
resources. Wear-resistant ceramic valves are mainly used in
electric power, petroleum, chemicals, metallurgy, mining, sewage
treatment and other industrial fields, especially in the face of
high wear, high corrosion, high temperature, high pressure and
other adverse conditions, ceramic valves also demonstrated its
superior performance. Ceramic valves to meet the high wear and
tear, the use of highly corrosive environment, in particular
outstanding feature is the long service life, performance and low
cost ceramic valve is far better than other comparable metal
valves. With the continuous development of science and technology
and progress of, ceramic materials from the formulation, molding,
machining and assembly process and other aspects of the technology
is more mature and complete, its outstanding performance ceramic
valve increasingly recognized by the valve industry professionals .
Using the successful experience of manufacturing ceramic valves can
also be applied to a wider range of engineering fields. ※ solar
polysilicon special valve (for: gas transportation silica fume) In
the delivery of silica fume, silica powder wrapped ball easily and
frequently open easily damage metal seal, causing leakage and other
problems, silica fume as reasons for the high hardness, the average
life of a very short ball. Jintai Merrill Lynch view of this
situation for the study of development of the application of silica
fume Shusong special ceramic valves, the use of strong corrosion
resistance of structural ceramics, and high corrosion-resistant
zirconium alloy materials so that the new valve longevity than the
original Fa door 6 times, to the solar polysilicon silicon powder
delivery device management brings an exciting good news! Features:
★, all parts are in contact with
