電動PVC球閥是工業(yè)自動化控制系統(tǒng)中的重要執(zhí)行機(jī)構(gòu)。電動球閥是根據(jù)閥瓣的這種移動形式繞閥桿的軸線作旋轉(zhuǎn)運動的閥門。閥座通口的變化是與閥瓣行程成正比例關(guān)系。主要用于截斷或接通管路中的介質(zhì),亦可用于流體的調(diào)節(jié)與控制,是工業(yè)自動化過程控制的一種管道壓元件。
Electric PVC ball valve is an important actuator in industrial automation control system. Electric ball valve is a valve that rotates around the axis of the valve stem according to the movement of the valve disc. The change of valve seat opening is in direct proportion to the valve disc stroke. It is mainly used to cut off or connect the medium in the pipeline, and it can also be used for fluid regulation and control. It is a pipeline pressure element for industrial automation process control.
電動PVC球閥的維修方法:
1、 Maintenance method of electric PVC ball valve:
1、非金屬零件清洗后應(yīng)立即從清洗劑中取出,不得長時間浸泡。
1. The non-metallic parts shall be taken out of the cleaning agent immediately after cleaning, and shall not be soaked for a long time.
2、清洗后需待被洗壁面清洗劑揮發(fā)后(可用未浸清洗劑的綢布擦)進(jìn)行裝配,但不得長時間擱置,否則會生銹、被灰塵污染。
2. After cleaning, assembly shall be carried out after the cleaning agent for the wall surface to be washed volatilizes (it can be wiped with a silk cloth not soaked in the cleaning agent), but it shall not be put aside for a long time, otherwise it will rust and be polluted by dust.
3、分解下來的單個零件可以用浸洗方式清洗。尚留有未分解下來的非金屬件的金屬件可采用干凈的細(xì)潔的浸漬有清洗劑的綢布擦洗。清洗時須去除一切粘附在壁面上的油脂、污垢、積膠、灰塵等。
3. The disassembled individual parts can be cleaned by immersion. The metal parts that have not been decomposed can be scrubbed with clean, fine and clean silk cloth impregnated with cleaning agent. During cleaning, all grease, dirt, glue and dust adhering to the wall surface must be removed.
4、新零件在裝配前也需清洗干凈。
4. New parts shall also be cleaned before assembly.
5、裝配時應(yīng)不允許有金屬碎屑、纖維、油脂、灰塵及其它雜質(zhì)、異物等污染、粘附或停留在零件表面上或進(jìn)入內(nèi)腔。
5. During assembly, metal chips, fibers, grease, dust, other impurities and foreign matters are not allowed to contaminate, adhere to or stay on the surface of parts or enter the inner cavity.
6、只有卸除球閥前后的壓力,才能對球閥進(jìn)行拆卸分解操作。
6. Only when the pressure before and after the ball valve is removed can the ball valve be disassembled.
7、在對球閥的分解與再裝配過程,需要對有密封性零部件的保護(hù),特別是非金屬零部件,像O型圈等部件好使用專用的工具。
7. During the disassembly and reassembly of the ball valve, it is necessary to protect the sealing parts, especially the non-metallic parts, such as O-rings, with special tools.
8、球閥閥體重新裝配時螺栓一定要對稱、逐步、均勻地擰緊。
8. When reassembling the ball valve body, the bolts must be tightened symmetrically, step by step and evenly.
9、清洗劑應(yīng)與球閥中的橡膠件、塑料件、金屬件及工作介質(zhì)(例如燃?xì)?等均相容。工作介質(zhì)為燃?xì)鈺r,可用汽油(GB484-89)清洗金屬零件。非金屬零件用純凈水或酒精清洗。
9. The cleaning agent shall be compatible with rubber parts, plastic parts, metal parts and working media (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned with gasoline (GB484-89). Clean non-metallic parts with pure water or alcohol.
