RAYDO SKGV 11系列全衬聚氨酯刀闸阀使用手册浙江瑞得机械有限公司地址:浙江省温州市永嘉县宣达工业园电话:*************浙江瑞得机械有限公司地址:浙江省温州市永嘉县宣达工业园电话:*************安装阀门到管线上时特别注意事项:安装阀门时应使阀门处于关闭位置;安装前,将阀门、配管法兰、法兰密封预装好; 将阀门垂直吊起至安装位置; 法兰与管道使用点焊连接; 将阀门移走,完成焊接;冷却后再将阀门与配管法兰连接好;切勿将阀门装于配管法兰与管道直接焊接,法兰过热将导致聚氨酯损毁。
•一、安装指南1.1 安装前检查阀门铭牌,不要将阀门安装在超出阀门铭牌温度和额定压力的场所。
1.2 尽可能将阀门垂直地面安装,横装、斜装不利于阀门排渣和启闭。
1.3 阀门按照正确的流体方向安装,参见阀体侧向承压方向箭头。
做止回功能的阀门,应按介质回流方向安装。
1.4 与阀门连接的管线必须正确对中并有适当地支撑。
管线法兰的不对中可能导致阀体或法兰连接处的泄漏。
1.5 配管法兰应该是平面型的,以和聚氨酯阀衬上的密封环完全贴合。
推荐首选带颈对焊或承插焊平面型法兰。
在阀门的两侧都要求有法兰。
请勿使用平焊法兰。
软性法兰面伸缩节不得直接连接阀体,否则会造成内衬受挤压变形并咬死阀板,导致阀门无法动作。
• 1.6 在阀腔部位的螺纹孔要求特别注意并确保螺栓的正确长度。
超过允许的最大穿透深度将戳破阀体和阀衬导致阀门不能动作。
1.8 法兰螺栓按照交叉的顺序错开至少三个孔依次拧紧。
如果开车后法兰漏泄,用稍微大的力再拧紧法兰螺栓。
1.9 如果使用衬胶法兰或者凸面法兰,过大的法兰力矩可能导致阀门不能动作。
1.10 如果在阀板密封处出现漏泄,均匀地拧紧压盖密封螺栓, 力量应该刚刚能阻止泄漏为好。
过紧将可能导致阀门不能正常工作。
1.11 当阀门以水平与地面方向安装时,要确保执行机构有合适的支撑,保证执行器和阀门的对中性。
没有支撑可能由于没有正确对中而导致执行器或阀门故障。

刀闸阀技术说明00
刀闸阀刀闸阀从八十年代进入我国,在不到二十年的时间里,其使用范围从普通领域扩展到了更为广阔的各行各业,从矿山电厂的选煤、排矸、排渣,发展到了城市的污水处理,从一般的工业管道发展到了食品、卫生、医药等专业管道系统。
概述刀闸阀又称刀型闸阀、刀门闸阀、浆液阀、泥浆阀,它的启闭件是闸板,闸板的运动方向与流体方向相垂直,靠可以切割纤维材料的刀刃形闸板来切断介质,闸板有两个密封面,最常用的模式闸板阀的两个密封面形成楔形、楔形角随阀门参数而异,通常为50,楔式刀型闸阀的闸板可以做成一个整体,叫做刚性闸板;也可以做成能产生微量变形的闸板,以改善其工艺性,弥补密封面角度在加工过程中产生的偏差,这种闸板叫做弹性闸板。
阀体实际上不存在腔室,闸板在侧面导向槽内升降,并由底部的凸耳紧压在阀座上,如需达到较高的介质密封性时,可选用O形密封阀座实现双向密封。
刀闸阀具有较小的安装空间,工作压力低,不易堆积杂物,价格较低。
刀型闸阀关闭时,密封面可以只依靠介质压力来密封,即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封.大部分闸阀是采用强制密封的,即阀门关闭时,要依靠外力强行将闸板压向阀座,以保证密封面的密封性。
本类阀门在管道中一般应垂直安装。
刀型闸阀驱动方式:手动,链轮,电动,气动,液动,伞齿轮,电控液动和气液动等驱动方式。
刀型闸阀外形:明杆,暗杆两种。
刀型闸阀材质:铸铁、铸钢、碳钢、不锈钢、衬氟等。
刀型闸阀密封:硬密封,软密封,单面密封,双面密封等多种材质密封。
超薄型的刀闸阀以其体积小、流阻小、重量轻、易安装、易拆卸等优点彻底解决了普通闸阀、平板闸阀、球阀、截止阀、调节阀、蝶阀等类阀门的流阻大、重量大、安装难、占地面积大等的疑难问题。
刀闸阀出现后,大量的通用切断类阀门和调节阀门已被之取代。
到今天,全球刀闸阀用量最大的是美国和日本。
刀闸阀的使用范围为:1.采矿、洗洗煤、钢铁工业--用于洗洗煤管道、滤渣浆管道等、排灰管道;2.净化装置--用于废水、泥浆、污物及带有悬浮物的澄清水;3.造纸工业--用于任何浓度纸浆、料水混合物;4.电站除灰--用于灰渣浆液。

阀体和阀盖采用螺栓连接。
其动作和密封原理是:通过手轮带动阀杆螺母旋转,阀杆螺母驱动阀杆运动,阀杆与闸板连接,由于闸板两侧带有可在阀体导轨中移动的导向槽从而保证闸板上下移动,起到开关作用。
其密封靠介质压力作用在堆焊合金密封面的闸板与阀体上壤嵌的密封条来完成。
为了保证闸板与密封面的密封,采用F4密封条。
同时为考虑在工作条件下,内腔流体对阀盖冲蚀在阀盖上设有密封条结构,保证了阀门全开时的密封。

C67双向刀型闸阀说明书
C67 Bi-Directional Knife Gate Valveperimeter seat that provides bi-directional, bubble-tight shutoff.The seat is retained in the valve body by its trapezoidal shape.A relief area has been cast into the valve body behind the seat.Designed to overcome problems common to other perimeterseated designs, the relief area greatly reduces compression setof the seat, allowing it to maintain a tight shutoff performanceover varying service conditions. This unique valve design isavailable in cast stainless steel and carbon steel bodyconstruction and can be supplied with a wide variety of seatmaterials to address a range of application parameters.The C67 has been upgraded with the universal yoke designwhich provides greater range of valve application. The yoke platesinclude a lockout provision for both manual and actuated valves,while greatly simplifying the conversion of valve operators in thefield. The yoke plates also allow for easier mounting of mechanicaland proximity sensors.SpecificationsSize Range2” – 36”Pressure Rating2”-36” 150 psi (10.3 bar) CWP (cold working pressure)Consult factory for higher pressure designs.Temperature RatingAflas Seat 0°F (-18°C) to 400°F (204°C)Viton Seat -30°F(-34°C) to 350°F (177°C)EPDM Seat -50°F (-45°C) to 280°F (138°C)HNBR Seat -20°F (-29°C) to 280°F (138°C)Neoprene Seat -30°F (-34°C) to 180°F (82°C)Flange DrillingANSI 125/150 DrillingConsult factory for other flange drillings.TestingEvery Fabri-Valve Figure C67 valve is fully tested prior to shipment.Testing includes a body shell test, a seat test and a cycling test toinsure proper functioning of moving parts. Please consult thefactory for any special testing requirements.• Standard Shell Test: Hydro test at 1.5 times the rated CWP (coldworking pressure) – Zero allowable leakage• Standard Resilient Seat Test: Hydro test at 15 psi (1 bar) and therated CWP (cold working pressure) – Zero allowable leakage*U.S. Patent #5, 154,3972C67C67 3Trapezoidal Seat TechnologyThe C67 trapezoidal seat design provides bubble tight shutoff across the full pressure rating of the valve. When the gate is opened, the seat remains flush with the valve body, reducing turbulence and media build-up. As the gate is closed, the resilient seat is pushed into the body relief area, reducing compression set of the rubber and maintaining a long-term, tight seal.
