石油液化气磁翻柱液位计
一、产品,石油液化气磁翻柱液位计,的祥细资料:
UHZ-517C14石油液化气专用型磁翻柱液位计(侧装式)是公司引进吸收国外同类产品,并加以提高研制生产的产品。系列产品可以做到高密封、防泄漏和在高温、高压、高粘度、强腐蚀性条件下安全可靠地测量液位,全过程测量无盲区,显示醒目,读数直观,且测量范围大,配上液位报警、控制开关,可实现液位或界位的上、下限报警和控制,配上LB型液位变送器,可将液位、界位信号转换成二线制4,20mADC标准信号,实现远距离检测、指示、记录与控制。系列产品广泛用于电力、石油、化工、冶金、环保、船舶、建筑、食品等各行业生产过程中的液位测量与控制。
二、结构原理:
液位计根据浮力原理和磁性耦合作用原理工作的。当被测容器中的液位升降时,液位计主导管中的浮子也随之升降,浮子内的永久磁钢通过磁耦合传递到现场指示器,驱动红、白翻柱翻转180?,当液位上升时,翻柱由白色转为红色,当液位下降时,翻柱由红色转为白色,指示器的红、白界位处为容器内介质液位的实际高度,从而实现液位的指示。
三、适用范围:
该产品适用于易汽化的液体测量,尤其适合液化气介质的液位测量。其特点是用挡杆将液位计主导管内腔分成气化室和测量室,当液位计内液化气受温度影响,内部汽化而产生气泡时,气泡会顺着气化室往上冒,而不会进入测量室影响磁浮子工作,有效地阻止了因气泡造成磁浮子跳动,使液位计在液体介质大量气化时,也能可靠地工作。
适合容器内液体介质的液位、界位的测量。除现场指示,还可配远传变送器、报警(控制)开关,检测功能齐全。指示新颖,读数直观、醒目,观察指示器的方向可根据用户需要改变角度。测量范围大,不受储槽高度限制。指示机构与被测介质完全隔离,因而密封性好,可靠性高,使用安全。 结构简单,安装方便,维护费用低。

In 1938, the Japanese learned that the national Government established in XI Tang Tomb rotten "clip" taxes, tax officers live in 8 of Yan Dong village farmers home, troops at night, Yao was burned several houses. 1938 new morning of September 18, the Japanese team went to the countryside "sweep" from the kaiyang village line to Tung Yang Jia Qiao yan Temple wall and met Yang Jia溇 Zhou Dana (male) weeks because of long-term illness and can't work in the fields, the Japanese see his face from scratch without calluses, regard him as "Shina", thrust a knife at the scene of his death. The body was stabbed 7 times, wound 13. The same day, Trang bang village heard the Japanese come to "mop-up" are hiding, mother of 9 Zhou Guanbao Zhang Aying to drill a "dry mound", was discovered by the Japanese, a shot in the end. The same day, is 7 zhouhaijiangzhi grandfather Zhou Yingbao to escape the Japanese army, was found on the road, a shot in the end. In March 1939, the Japanese army in Yan Tomb raiding, has arrested 16 people, in fengqiao cigarettes this morning bang, killing 11 people on the River, East meeting point in wood qiaotu in the afternoon killing 4 people on the Riverside. Gu Tong is a Japanese go speak the Shanghai dialect, later to be called Gu Tong as "kill left." On January 18, 1943, the elves, five thousand or six thousand, water and land go hand in hand "mop-up" jiaxing area west of the railway, Yan Tomb area fall. March 6, Niu Shan (County Government II section chief) carrying its child Niu Jun (strict Tomb seventh district Chang) and the District Assistant Yu Xuchu, and players Jin Fuqin, and Shen Baosheng, six people received Wujiang underground County Government notification

五、石油液化气磁翻柱液位计使用:
1. 配套仪表及附件详细内容具体见相应仪表附件
。
2. 为防止运输或搬运过程中浮子上下移动造成损坏,特用液位计出厂配套的校正磁钢在主导管外侧(贴有彩色标识)将磁性浮子吸住。所以在收到产品或安装
后,请将校正磁钢取下,以便浮子能随液位上下移动,使用前若磁翻柱翻转颜色不一致,可用校正磁钢将其吸顺,仪表即可正常工作。
3. 液位计安装完毕后,需用磁钢进行校正,对磁翻柱导引一次,使零位以下显示红色,零位以上显示白色。 4. 液位计可根据用户要求配加热夹套或电伴热装置,如用户订货时没有选择该选项,而在安装后自行采用伴热管路时,必须选用非导磁材料,且自配伴热装置
产生的温度不能超过液位计的额定温度。
5. 液位计投入运行时,应先打开上引液管阀门,然后,漫漫开启下引液管阀门,让液体介质平稳地进入主导管,避免液体介质带着浮子急速上升,造成磁翻柱
翻转失灵或翻乱(若遇此现象,可用磁钢重新校正)。

一、阀门的选型步骤
1.明确阀门在设备或装置中的用途,确定阀门的工作条件:适用介质、工作压力、工作温度等等。
2.确定与阀门连接管道的公称通径和连接方式:法兰、螺纹、焊接等。
3.确定操作阀门的方式:手动、电动、电磁、气动或液动、电气联动或电液联动等。
4.根据管线输送的介质、工作压力、工作温度确定所选阀门的壳体和内件的材料:灰铸铁、可锻铸铁、球墨铸铁、碳素钢、合金钢、不锈耐酸钢、铜合金等。
5.确定阀门的型式:闸阀、截止阀、球阀、蝶阀、节流阀、安全阀、减压阀、蒸汽疏水阀、等。
6.确定阀门的参数:对于自动阀门,根据不同需要先确定允许流阻、排放能力、背压等,再确定管道的公称通径和阀座孔的直径。
7.确定所选用阀门的几何参数:结构长度、法兰连接形式及尺寸、开启和关闭后阀门高度方向的尺寸、school)], 4 4 house building as well as more than 1000 copies of books, more than 10 kinds of collection of newspapers and magazines, fires burnt down.

连接的螺栓孔尺寸和数量、整个阀门外型尺寸等。
8.利用现有的资料:阀门产品目录、阀门产品样本等选型适当的阀门产品。
二、阀门的选型依据
1.所选用阀门的用途、使用工况条件和操纵控制方式。
2.工作介质的性质:工作压力、工作温度、腐蚀性能,是否含有固体颗粒,介质是否有毒,是否是易燃、易爆介质,介质的黏度等等。
3.对阀门流体特性的要求:流阻、排放能力、流量特性、密封等级等等。
4.安装尺寸和外形尺寸要求:公称通径、与管道的连接方式和连接尺寸、外形尺寸或重量限制等。?对阀门产品的可靠性、使用寿命和电动装置的防爆性能等的附加要求。(在选定参数时应注意:如果阀门要用于控制目的,必须确定如下额外参数:操作方法、最大和最小流量要求、正常流动的压力降、关闭时的压力降、阀门的最大和最小进口压力。)根据上述选型阀门的依据和步骤,合理、正确地选型阀门时还必须对各种类型阀门的内部结构进行详细了解,以便能对优先选用的阀门做出正确的抉择。管道的最终控制是阀门。阀门启闭件控制着介质在管道内的流束方式,阀门流道的形状使阀门具备一定的流量特性,在选型管道系统最适合安装的阀门时必须考虑到这一点。
三、阀门选型原则
1.截止和开放介质用的阀门流道为直通式的阀门,其流阻较小,通常选型作为截止和开放介质用的阀门。向下闭合式阀门(截止阀、柱塞阀)由于其流道曲折,流阻比其他阀门高,故较少选用。在允许有较高流阻的场合,可选用闭合式阀门。
2.控制流量用的阀门通常选型易于调节流量的阀门作为控制流量用。向下闭合式阀门(如截止阀)适于这一用途,因为它的阀座尺寸与关闭件的行程之间成正比关系。旋转式阀门(旋塞阀、蝶阀、球阀)和挠曲阀体式阀门(夹紧阀、隔膜阀)也可用于节流控制,但通常只能在有限的阀门口径范围内适用。闸阀是以圆盘形闸板对圆形阀座口做横切运动,它只有在接近关闭位置时,才能较好地控制流量,故通school)], 4 4 house building as well as more than 1000 copies of books, more than 10 kinds of collection of newspapers and magazines, fires burnt down.

常不用于流量控制。
3.换向分流用的阀门根据换向分流的需要,这种阀门可有三个或更多的通道。旋塞阀和球阀较适用于这一目的,因此,大部分用于换向分流的阀门都选取这类阀门中的一种。但是在有些情况下,其他类型的阀门,只要把两个或更多个阀门适当地相互连接起来,也可作换向分流用。
4.带有悬浮颗粒的介质用阀门当介质中带有悬浮颗粒时,最适于采用其关闭件沿密封面的滑动带有擦拭作用的阀门。如果关闭件对阀座的来回运动是竖直的,那末就可能夹持颗粒,因此这种阀门除非密封面材料可以允许嵌入颗粒,否则只适用于基本清洁的介质。球阀和旋塞阀在启闭过程中对密封面均有擦拭作用,故适宜用在带有悬浮颗粒的介质中。目前,无论在石油、化工,还是在别的行业的管道系统,阀门应用、操作频率和服务千变万化,要控制或杜绝那怕是低微的泄漏,最重要、最关键的设备还数阀门。管道的最终控制是阀门,阀门在各个领域的服务和可靠表现是独一无二的。
