主要零件和材質(zhì) Main parts and materials 產(chǎn)品結(jié)構(gòu)特點(diǎn) Construction features 1、 超長(zhǎng)壽命設(shè)計(jì) 閥座、密封圈由金屬材料制成，且做表面硬化處理，就算啟閉頻繁，閥門(mén)仍能保持高的密封性能，杜絕了多層次密封結(jié)構(gòu)不耐沖刷等弊端，極大提高了閥門(mén)的使用壽命； 2、依靠扭矩密封 閥門(mén)至始至終都能保持的雙向密封性能，閥門(mén)密封不依靠介質(zhì)力，由驅(qū)動(dòng)裝置提供的扭矩實(shí)現(xiàn)密封，閥門(mén)在高、低壓下均能可靠密封。密封性能檢測(cè)結(jié)果符合API609、ISO5208等標(biāo)準(zhǔn)之規(guī)定； 3、閥座/密封圈可現(xiàn)場(chǎng)更換 可更換式閥座/密封圈設(shè)計(jì)，便于閥門(mén)現(xiàn)場(chǎng)維護(hù)保養(yǎng)； 4、填料密封的高性能 采用組合式填料密封系統(tǒng)，確保閥門(mén)泄漏率≤20ppm?？蛇x用動(dòng)載密封結(jié)構(gòu)，使填料持久密封，延長(zhǎng)填料免維護(hù)周期； 1. Long life design Seat, sealing completely made of metal materials, and surface hardening treatment, even if the opening and closing is frequent, can still maintain a high sealing performance of the valve, put an end to the multi-layer sealing structure not scour resistance and other shortcomings, greatly improve the service life of the valve; 2. Rely on torque seal Valve throughout can keep superior two-way sealing performance and valve sealing force does not rely on media, completely provided by the drive torque seal, valve can reliable sealing under high and low pressure. The sealing performance test results are in accordance with the standards of API 609 and ISO5208. 3. The seat/sealing ring can be replaced on site Replaceable seat/sealing ring design to facilitate valve site maintenance; 4. High performance of packing seal The combined packing sealing system is adopted to ensure the maximum leakage rate of valve is less than 20ppm. The movable seal structure can be used to keep the stuffing durable and prolong the packing period. 產(chǎn)品特征 Spericfications 適用介質(zhì)：水、氣、油品、天然氣和酸堿腐蝕性介質(zhì) 適用溫度：-196~350℃ 驅(qū)動(dòng)方式：手動(dòng)、氣動(dòng)、電動(dòng)、液動(dòng)等 公稱壓力：1.0~6.3MPa 公稱通徑：DN100~3600mm Applicable media: water, gas, oil, gas and acid and alkali corrosive medium Applicable temperature: -196~350℃ Driver: manual, pneumatic, electric, hydraulic, etc Nominal pressure: 1.0~6.3MPa Nominal size: DN100~3600mm 技術(shù)規(guī)范 Technical specification
