進(jìn)口法蘭閘閥德國(guó)洛克質(zhì)量?jī)?yōu)異 價(jià)格美麗 

一、進(jìn)口法蘭閘閥結(jié)構(gòu)優(yōu)點(diǎn)：

1.產(chǎn)品設(shè)計(jì)制造按API標(biāo)準(zhǔn)，密封可靠，性能優(yōu)良、能與進(jìn)口設(shè)備配套使用。

2.600Lb以上閘板與閥座密封采用司太立（stellite）鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，耐腐蝕，抗擦傷性能好、使用壽命長(zhǎng)

3.閥桿經(jīng)調(diào)質(zhì)和表面氮化處理，有良好的抗腐蝕性和抗擦傷性。

4.采用楔式彈性閘板結(jié)構(gòu)，中大口徑設(shè)置滾動(dòng)軸承，啟閉輕松。

5.閥體材料品種齊全，填料、墊片根據(jù)實(shí)際工況或用戶要求合理選配，能適用于各種壓力、溫度及介質(zhì)工況。

6.1500LB、2500LB中腔采用壓力自緊式密封結(jié)構(gòu)。密封性能隨內(nèi)壓升高而升高，可靠性高。

7.倒密封采用不銹鋼螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，倒密封可靠，填料更換和維修可在不停機(jī)情況下進(jìn)行，方便快捷不影響系統(tǒng)運(yùn)行。

1. The product is designed and manufactured according to API standard, with reliable sealing, excellent performance, and can be used with imported equipment.

2. The seal between the gate and the valve seat above 600Lb is made of Stellite cobalt based hardfacing, which is wear-resistant, high temperature resistant, corrosion-resistant, abrasion resistant and long service life

3. After tempering and surface nitriding treatment, the valve rod has good corrosion resistance and scratch resistance.

4. Wedge type elastic ram structure is adopted, and rolling bearing is set in medium and large diameter, so it is easy to open and close.

5. The valve body materials are complete, and the packing and gasket are reasonably selected according to the actual working conditions or user requirements, which can be applied to various pressure, temperature and medium working conditions.

6.1500lb and 2500lb middle cavities adopt pressure self tightening sealing structure. The sealing performance increases with the increase of internal pressure and the reliability is high.

7. The inverted seal is made of stainless steel threaded connection seal seat or body hardfacing austenitic stainless steel. The inverted seal is reliable. The replacement and maintenance of packing can be carried out without shutdown, which is convenient and fast without affecting the system operation.
