上海厂家FIP 意大利进口电动塑料球阀

意大利双由令PVDF双由令连接球阀，FIP塑料球阀
FIP has developed a new ball valve type VK Dual Block to
introduce an advanced standard of reference in
thermoplastic valve design.
VKD is a (true) union lock ball valve, which stands up to the
most severe industrial application requirements.
Absolute trouble free service is the basic principle to be
achieved with the true blocked union design.
Size range from d 16 mm up to d 63 mm
Jointing by socket or butt welding, threaded or flanged
connections
Maximum working pressure: 16 bar at 20 ; for full details
see following page
Patented system DUAL BLOCK : the new locking device
ensures the nuts are held in position even under severe
service conditions: i.e. vibration or thermal expansion
Easy removal of the valve body from the system, allowing
quick replacement of O-rings and ball seats without additional
equipment
SEAT-STOP seat and seal design.Axial pipe loads block with
micro adjustment of ball seal.
In the closed position the pipeline can be disconnected
downstream from the valve without leakage
Hand operated version with ergonomic U-PVC hand lever,
provided with locking device on request
Possibility to install electric or pneumatic actuators by means
of GR-PP mounting kits with standard drilling (ISO 5211 F03-
F04-F05-F07).

浅层砂过滤器利用深层介质对原水进行深层过滤，能有效地去除颗粒物和降低浊度。若装上特定的滤料，例如活性炭，沸石等，还可以吸附去除相应的有机物、离子等。
工作原理
    过滤状态：当系统处于过滤状态时，加压水从滤罐进口流入布水系统，均匀的到达滤料层，当水流过滤料层时，悬浮物被滤料截留。过滤器底部带有精密缝隙的集水器，过滤后的水被均匀收集，并流出过滤器。集水器上精密的缝隙能有效防止滤料的流失。
    反冲洗状态：随着杂质在滤料层中的不断积聚，压力损失不断增加，当压差增加到某一设定值时（或达到某一设定的时间值时），系统将自动转换至反洗状态。加压水通过过滤器底部集水装置进入滤料层，对其进行冲刷，使截流的污染物脱落并排出过滤器。
产品特点
    采用全自动控制过滤系统，采用模块化设计，根据流量的大小，选择多个过滤单元。可采用时间，压差等多种方式自动启动反冲洗，系统内各过滤单元依次进行反冲洗，其他单元仍然在过滤。反冲洗效率高，反冲洗时间短，反冲洗时节水。滤料具有更好的耐细菌污染能力，反冲洗效果更好。
产品应用
    工业用水的过滤。如：钢厂氧枪水、褐炉、热交换器供水的过滤等，可过滤掉水中的杂质，避免管路及喷嘴的堵塞。
    工业循环水的旁滤系统，生产水的再循环、工业废水处理。
    原水的处理。可对地表河水，湖水、海水、水库水、井水以及城市自来水作为水源的城市小区分质供水等进行过滤，除去水中的砂粒、悬浮物、藻类、有机物等。
    农业灌溉。尤其适用于高流量、杂质含量好的水源，如农田水利灌溉、公园及高尔夫球场上草坪的浇灌等。 
    食品加工业用水，造纸行业，电厂工业循环水的处理等，工业及医疗用纯净水的预处理。
    水产业、游泳池及水上乐园等行业。
