平板闸阀 FLAT PLATE GATEVALVE
(K)WPZ43F/943F/543F/643F、(K)DPZ43F/943F/543F/643F
平板闸阀的主要特点The main features of plate gate valve
1、本公司引进国外平板闸阀的先进技术，进行了重大的改进，其结构合理，密封可靠，维护方便。
2、闸板、阀座经特殊工艺处理、喷焊硬质合金，聚四氟乙烯，实现双重密封。并可注油脂辅助密封双重保护，密封更可靠，使用寿命更长。
3、本阀独有三重可调式填料结构，确保与阀盖、阀杆密封可靠。法兰连接尺寸按JB/T79, 亦可根据客户要求指定标准生产。
4、有导流孔平板闸阀用于需通球清管的管线，无导流孔的平板闸阀用于不需通球清管的管线上。
5、阀门阀体内腔内压力升高时，阀座可自动退让泄掉过高的压力。
6、本阀传动机构确保阀门启闭灵活，其启闭力矩仅为普通阀门的1/3～1/2。
7、气动闸阀启、闭迅速，带缓冲机构，开闭无冲击，气动、手动转换结构新颖、操作灵活、方便可靠。
8、调节型平板闸阀适用于泵、站出口及其它需调节介质的管路上，调节和截断介质。
9、本阀可广泛适用于天然气、石油、化工、环保等输送管线、放空系统和油、汽储存装置上，用作启闭设备。
10、本公司同时还生产调节型等特殊要求的平板闸阀。
11、电动平板闸阀一般选用扬州电力修造厂或天津二通的电动头，也可根据用户需要选配英国罗括克Rotork(IQ)系列、德国欧玛Aul(SA系列)或由客户在国内选配任何厂家的电动头。
1,The company has introduced foreign advanced technology of flat gate valve and made significant improvement Its structure is reasonable,sealing is reliable and maintenance is convenient
2,Gate and seat are processed by special process and sprayed with cemented carbide and polytetrafluoroethylene to achieve double sealing.And can grease auxiliary seal double protection,seal more reliable, longer service life.
3,The unique triple adjustable packing structure of this valve ensures reliable sealing with bonnet and stem.Flange connection size according to JB/T79,also according to customer requirements specified standards.
4.The plate gate valve with orifice is used in the pipeline requiring ball pigging,and the plate gate valve without orifice is used in the pipeline not requiring ball pigging.
5,valve body cavity pressure rise,the valve seat can be automatically back off from too high pressure.
6,the valve drive mechanism to ensure that the valve open and close flexibly,the opening and closing torque is only1/3~1/2 of the ordinary valve.
7,pneumatic gate valve open and close quickly,with buffer mechanism,open and cose without impact,pneumatic,manual conversion structure,flexible,convenient and reliable.
8,regulating type flat gate valve is suitable for pump,station outlet and other need to adjust the medium of the pipeline,regulation and cut off the medium.
9,the valve can be widely used in natural gas,petroleum,chemical,environmental protection and other transmission pipelines,vent system and oil,gas storage device,as a device for opening and closing.
10,The company also produces flat gate valves for regulating and other special requirements.
11,electric plate gate valve generally choose yangzhou electric power repair factory or tianjin ertong electric head,also according to the needs of users with Rotork(IQ)series,Germany omar Aul(SA series)or by customers in the domestic selection of any manufacturers electric head.
