7.冶金系统用电动执行器

7. Valves for metallurgical systems
   冶金系统用电动执行器,由于介质常为粉状和悬浮固体颗粒状,加之温度较高,故对阀门的耐磨、耐温及耐蚀等要求较高。

    Valve used in metallurgical system, due to the medium is often powdery and suspended solid particles, coupled with a higher temperature, so the valve wear, temperature and corrosion resistance and other requirements are higher.
    冶金系统用阀发展的具体类型、参数如下:

    The specific types and parameters of valve development for metallurgical systems are as follows :

⑴ 圆顶阀

⑴ Dome Valve
    用于火力发电厂气力除灰、进料、放料系统的圆顶阀。该阀由阀体、主动轴、从动轴、球体等组成,其公称通径:DN50~300mm;工作压力:PN1.0~0.6MPa;最顶使用温度:1050℃。设计该阀时,其密封面应考虑采用喷涂钴基碳化钨合金材料,使其更加坚硬,增强耐磨性能.

    Dome valve for pneumatic ash removal, feeding and discharging system of thermal power plant. The valve is composed of a valve body, a driving shaft, a driven shaft, a sphere, etc, and its nominal diameter is DN50.~ 300 mm;working pressure: PN 1.0~ 0.6 MPa;maximum service temperature: 1050.When designing the valve, the sealing surface of the valve should be considered by spraying cobalt based tungsten carbide alloy material to make it more hard and wear resistant. 

⑵ 排灰平板闸阀

⑵Ash plate gate valve

    用于炼钢厂炼铁除灰系统的“排灰平板闸阀”。该除灰系统的介质——“灰粉”,不仅形状是颗粒的(有时是分散形状,有时是混合形状),而且具有一定的粘性,还夹有一氧化碳(CO)。由于介质“灰粉”中的颗粒,阀座往往有不同程度的损伤、擦伤、磨损,故,要求其“排灰平板闸阀”的主件,例如闸板、阀座等零部件均应具有较强的耐磨性。炼铁除灰系统工况的使用压力在0.25MPa左右的低压范围内;温度在≤250℃的范围内(一般情况下为常温,有时瞬间温度可达250℃);公称管径仅从DN50mm~DN400mm(DN300mm的管径最常见)。

    Ash discharge flat gate valve" for ash removal system of ironmaking in steelworks.The medium of the ash removal system, the " ash powder, " Is not only of the shape of a particle ( sometimes a dispersed shape, sometimes a mixed shape ), and it has a certain viscosity, and also has carbon monoxide ( CO ). As the medium " ash powder " in the particles, the valve seat often have varying degrees of damage, abrasion, wear, it is required to " ash plate gate " of the main pieces, the operating pressure of ash removal system is in the range of 0.25 MPa;temperature in the range of 250 (normal temperature, sometimes instant temperature up to 250);~ dn 400 mm (DN 300 mm diameter is the most common).

    该阀其结构如采用带导流孔,并且“加大密封面”的密封设计,不仅能提高其耐磨性;满足其密封性能;而且能避免灰粉进入阀体底腔。在设计中,可充分利用现行带导流孔平板闸阀产品,将阀座改为“加大密封面”的密封状态。对耐磨性而言,其金属对金属硬密封寿命虽最长,但金属对金属“加大密封面”的硬密封,一则标准上允许漏,(如设计为零泄漏成本将十分高昂且加工难度大);二则密封不如非金属材料。其密封不如非金属材料,是因为金属表面磨蚀时会产生一层氧化物,尽管这层氧化物覆盖在受到腐蚀作用的部位上,能减慢金属的进一步腐蚀,但如果发生滑动的话,该层氧化物就会被清除,使裸露出来的金属表面受到进一步的腐蚀,从而加快磨损,削弱其密封性能。而采用非金属材料,不仅能节约成本,降低加工难度,而且能保证其密封性能。
   由于钢厂炼铁除灰系统的工况温度一般为常温,有时瞬间最顶温度也只有250℃。故采用非金属材料(建议采用对位聚苯)作密封面,既可以满足其工况温度、耐磨,又可以满足其密封性能。非金属材料——对位聚苯,适用温度为≤300℃, 且比硬质的PTFE更硬,能满足炼铁厂除灰系统的工况,不失为较理想的密封面材料。阀座材料建议采用1Cr13。

The valve structure, such as the use of diversion holes, and "increase the sealing surface" of the seal design, not only can improve its wear resistance;to meet its sealing performance;the utility model can prevent the ash powder from entering the bottom cavity of the valve body.In the design, can make full use of the current flat gate valve products with diversion hole, the seat will be changed to "increase the sealing surface" of the seal.In terms of wear resistance, although the metal-to-metal hard seal has the longest service life, the metal-to-metal hard seal of "enlarging the sealing surface" allows leakage according to one standard.( if the design is zero leakage costs will be very high and the processing is difficult ); second, the seal as non-metallic materials.The reason why the seal is inferior to non-metallic materials is that when the metal surface is abraded, it will produce a layer of oxide, although this layer of oxide is covered on the corroded part.Further corrosion of the metal can be slowed down, but if sliding occurs, the oxide layer of the layer will be removed so that the exposed metal surface will be further corroded so as to speed up the wear and tear, and weaken its sealing performance. The use of non-metallic materials, not only to save costs, reduce processing difficulties, but also to ensure its sealing performance.
   Because the working temperature of the ash removal system is generally normal temperature, sometimes the instantaneous maximum temperature is only 250.Therefore, the use of non-metallic materials ( the proposed use of para polyphenyl ) as a sealing surface, can not only meet the operating temperature, wear resistance, but also meet the sealing performance. Non-metallic materials-Counterpoint polyphenyl, applicable temperature of 300,  It is harder than the hard PTFE and can meet the working condition of ash removal system in ironworks.The seat material is recommended to be 1Cr13.

⑶ 耐强酸腐蚀的不锈钢阀

⑶ Strong acid corrosion resistant stainless steel valve

    冶金系统用耐强酸腐蚀的不锈钢阀。该阀其公称通径:DN50~2400 mm;公称压力0.05~1.6MPa;最顶使用温度:1050℃。

8. 氧化铝工业用电动执行器
      氧化铝工业在生产过程中,介质多为碱性泥浆和颗粒状物质,结疤现象极为严重,且介质对阀门体腔及内件的冲蚀现象也很严重。因此,氧化铝工业用阀要求其抗结疤耐结疤;抗冲蚀耐冲蚀。
      集氧化铝生产系统中普通结构的闸阀、截止阀、球阀等众多之长于一身的料浆阀(直通式截止阀),不仅抗结疤耐结疤,而且抗冲蚀耐冲蚀,是氧化铝生产用阀的理想产品。该阀的整体结构采用Y型结构,即阀杆中心线于介质流动方向成45°夹角,连接形式为法兰连接;支架为光杆;密封面堆焊硬质合金;阀体采用两开式、中间夹阀座的形式,为防止介质对体腔内的冲蚀,在体腔内受冲刷较严重的部位镶嵌耐磨的硬质合金钢圈。
     该阀的公称压力级为CL150(PN2.0MPa)、CL300(PN5.0 MPa)、CL400(PN6.4MPa);公称通径:DN50~350 mm;工作温度:≤450℃。

8.In the production process of alumina industry, most of the are alkaline slurry and granular material, and the phenomenon of scarring is very serious, and the medium is also very serious to the body cavity and inner parts of the valve erosion phenomenon. Therefore, the alumina industry valve requires its scar resistance and scar resistance; Erosion resistance. Erosion resistance. Set alumina production system in the ordinary structure of the gate valve, globe valve, ball valve and so on numerous length in one slurry valve (straight-through globe valve). Not only scar resistant and erosion resistant, but also erosion resistant, is an ideal product for alumina production valves. The whole structure of the valve is Y-type, i.e., the stem centerline is angled at 45°in the flow direction of the medium, and the connection form is flanged. The support is light pole; Surfacing hard alloy with sealed surface; The valve body adopts the form of two open and middle clamp seats. In order to prevent the erosion of the medium to the body cavity, hard alloy steel rings are embedded in the parts of the body cavity where the erosion is more serious. The nominal pressure class of the valve is CL150 (PN2.0MPa), CL300 (PN5.0 MPa), CL400 (PN6.4MPa); Nominal size: DN50~350 mm; Working temperature: ≤450℃.
