進口襯氟止回閥推薦德國洛克

一、進口襯氟止回閥描述：

德國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(nèi)腔、閥體、閥蓋、閥瓣、復位彈簧（即化學介質(zhì)過流部件）部件均選用優(yōu)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(zhì)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(zhì)的管路上防止介質(zhì)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.

二、進口襯氟止回閥結(jié)構(gòu)特點：

1.流體阻力小，密封面受介質(zhì)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(qū)內(nèi)也能產(chǎn)生足夠的密封比壓，保證閥門在低壓力區(qū)密封的可靠性。

3．保證管路介質(zhì)絕對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(huán)保、石化、原油和天然氣等輸送腐蝕性液體管道的理想用閥。

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.
