进口衬氟止回阀质优价廉德国洛克

一、进口衬氟止回阀结构特点：

1.流体阻力小，密封面受介质的冲刷和侵蚀小。

2. 除了阀体，阀瓣外，复位弹簧也全部包衬了耐腐蚀的氟塑料，设计合理的弹簧，使阀瓣在低压区内也能产生足够的密封比压，保证阀门在低压力区密封的可靠性。

3．保证管路介质绝对不与阀门壳体材料直接接触，耐腐蚀性能极好，是化工、制药、电子、环保、石化、原油和天然气等输送腐蚀性液体管道的理想用阀。

1. The fluid resistance is small, and the sealing surface is scoured and eroded by the medium.

2. In addition to the valve body and disc, all the return springs are lined with corrosion-resistant fluoroplastics, and reasonable springs are designed to make the disc produce enough sealing pressure in the low-pressure area, so as to ensure the reliability of the valve sealing in the low-pressure area.

3. Ensure that the pipeline medium does not contact directly with the valve shell material, and the corrosion resistance is excellent. It is an ideal valve for transporting corrosive liquid pipelines such as chemical, pharmaceutical, electronic, environmental protection, petrochemical, crude oil and natural gas.

二、进口衬氟止回阀描述：

德国LOCKE洛克进口衬氟止回阀外壳体采用熔模精密铸造，强度高、外观光洁，与液体接触内腔、阀体、阀盖、阀瓣、复位弹簧（即化学介质过流部件）部件均选用优良的耐腐蚀材料（氟塑料）作为衬里或包覆材料适用在-50～150℃的各种浓度的王水、流酸、盐酸、氢氟酸和各种有机酸、强酸、强氧化剂，还适用于各种浓度的强碱有机溶剂以及其它腐蚀性气体，液体介质的管路上使用，FEP还适用于各种浓度的强碱有机溶剂以及其它腐蚀性气体、液体介质的管路上防止介质倒流使用。

The shell of Locke lock imported fluorine lined check valve is made of investment casting, with high strength and smooth appearance. The inner cavity, valve body, valve cover, valve disc and return spring (i Fluoric acid and various organic acids, strong acids and strong oxidants are also suitable for the use of various concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipelines. FEP is also suitable for the use of various concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipelines to prevent the backflow of media.
