针型阀用途及介绍|阀门资讯_非标阀门
http://www.cnast.cn/post/758.html
针型阀 针型截止阀 用途及介绍 针型阀是一种可以精确调整的阀门，用途较其它阀门相对广泛些。 针型阀主要参数 公称压力 PN2.5PN4PN6.4PN16PN32Mpa 公称通径 DN5 DN25 适用介质 油 水 气等多种非腐蚀性或腐蚀性介质 适用温度 -20 440 -70 -240 540 570 等 制造材料 20# 1Cr18Ni9Ti 304 316 316L 12Cr1Mov等一般情况下，针型阀门材料应根据其参数及材料的性能按本标准选用，并应符合有关产品标准的规定。 特殊情况下针型阀门的技术要求如下 灰铸铁制针型阀门 用于公称压力pN 1.0MPa，温度为10 200 的水、蒸气、空气、煤气及油类等介质的灰铸铁制阀门。 可锻铸铁制针型阀门 用于公称压力pN 2.5MPa，温度为-30 300 的水、蒸气、空气及油类等介质的可锻铸铁制阀门。 球墨铸铁制针型阀门 用于公称压力pN 4.0MPa，温度为-30 350 的水、蒸气、空气及油类等介质的球墨铸铁制阀门。 高温钢制针型阀门 用于公称压力pN 16.0MPa，温度小于或等于550 的蒸气及石油产品等介质的高温钢制阀门。
详解正确选择阀门电动装置应注意的问题|阀门资讯_非标阀门
http://www.cnast.cn/post/1157.html
操作力矩 操作力矩是选择阀门电动装置的最主要参数，电动装置输出力矩应为阀门操作最大力矩的1.2 1.5倍。 操作推力 阀门电动装置的主机结构有两种 一种是不配置推力盘，直接输出力矩;另一种是配置推力盘，输出力矩通过推力盘中的阀杆螺母转换为输出推力。 但如出现下列情况便可能导致超负荷 一是电源电压低，得不到所需的转矩，使电机停止转动;二是错误地调定转矩限制机构，使其大于停止的转矩，造成连续产生过大转矩，使电机停止转动;三是断续使用，产生的热量积蓄，超过了电机的允许温升值;四是因某种原因转矩限制机构电路发生故障，使转矩过大;五是使用环境温度过高，相对使电机热容量下降。 通常，过负荷的基本保护方法是 对电机连续运转或点动操作的过负荷保护，采用恒温器;对电机堵转的保护，采用热继电器;对短路事故，采用熔断器或过流继电器。 门厂,咨询热线:0577-66998891)公司专业生产:常规阀门, 陶瓷球阀. 陶瓷刀型闸阀,陶瓷旋转阀, 陶瓷蝶阀. 门、陶瓷耐磨材料、常规阀门等产品研发与生产的高新技术企业.公司坚持引进国外先进技术,结合国内实际情况的原则,所研制的各类新型高强度耐磨材料工程 陶瓷阀.
