進口襯氟止回閥的分類-德國洛克

進口襯氟止回閥結構特點：

1.流體阻力小，密封面受介質的沖刷和侵蝕小。

2. 除了閥體，閥瓣外，復位彈簧也全部包襯了耐腐蝕的氟塑料，設計合理的彈簧，使閥瓣在低壓區內也能產生足夠的密封比壓，保證閥門在低壓力區密封的可靠性。

3．保證管路介質*不與閥門殼體材料直接接觸，耐腐蝕性能極好，是化工、制藥、電子、環保、石化、原油和天然氣等輸送腐蝕性液體管道的理想用閥。

進口襯氟止回閥描述：

德國《DE LOCKE》洛克進口襯氟止回閥外殼體采用熔模精密鑄造，強度高、外觀光潔，與液體接觸內腔、閥體、閥蓋、閥瓣、復位彈簧（即化學介質過流部件）部件均選用優良的耐腐蝕材料（氟塑料）作為襯里或包覆材料適用在-50～150℃的各種濃度的王水、流酸、鹽酸、氫氟酸和各種有機酸、強酸、強氧化劑，還適用于各種濃度的強堿有機溶劑以及其它腐蝕性氣體，液體介質的管路上使用，FEP還適用于各種濃度的強堿有機溶劑以及其它腐蝕性氣體、液體介質的管路上防止介質倒流使用。

Description of imported fluorine lined check valve
German de The shell of fluorine lined check valve imported from Locke is investment casting, with high strength and smooth appearance. The parts of inner cavity, valve body, valve cover, valve disc and return spring (i.e. chemical medium flow parts) are made of excellent corrosion-resistant materials (fluoroplastics) as lining or coating materials, which are suitable for aqua regia, flowing acid, hydrochloric acid and hydrofluoric acid of various concentrations from - 50 ℃ to 150 ℃ Acid and all kinds of organic acids, strong acids, strong oxidants, also suitable for various concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipeline use, FEP is also suitable for various concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipeline use to prevent medium backflow.
