J17系列三密封復(fù)合閥是公司最杰出的創(chuàng)新產(chǎn)品，在閥門(mén)節(jié)流保護(hù)和密封保護(hù)上進(jìn)行創(chuàng)新，增加的兩個(gè)密封不僅能起到密封的作用，同時(shí)也起到保護(hù)主密封的作用，閥門(mén)的使用壽命也變得更長(zhǎng)；
The J17 series three-seal globe valve is the company’s most outstanding innovative product. Innovations are made in valve throttling protection and sealing protection. The two additional seals can not only play a role in sealing, but also play a role in protecting the main seal. The service life has also become longer;
J17系列三密封復(fù)合閥是在J16/J26/J36系列雙密封復(fù)合閥的密封基礎(chǔ)上，只保留了原來(lái)的閥體樣式，新增一道密封面，并做了更多更進(jìn)一步的改進(jìn)；
The J17 series three-seal globe valve is based on the sealing of the J16/J26/J36 series of double-seal compound valves, only retaining the original valve body style, adding a new sealing surface, and making more and further improvements;
閥門(mén)關(guān)閉時(shí)，按照級(jí)密封面--->第三級(jí)密封面--->第二級(jí)密封面的順序依次關(guān)閉，三個(gè)密封面都實(shí)現(xiàn)了密封效果，密封性能更加優(yōu)異，實(shí)現(xiàn)零泄露；
When the valve is closed, it is closed in the order of the first sealing surface --->the third sealing surface--->the second sealing surface. All three sealing surfaces have achieved the sealing effect, the sealing performance is more excellent, and zero leakage is completely realized;
閥門(mén)開(kāi)啟時(shí)，按照第二級(jí)密封面--->第三級(jí)密封面--->級(jí)密封面的順序依次打開(kāi)，更好的保護(hù)了第二級(jí)主密封；
When the valve is opened, it is opened in the order of the second sealing surface--->the third sealing surface--->the first sealing surface, which better protects the second main seal;
雖然閥內(nèi)件變的復(fù)雜，但我們的J17系列相比同規(guī)格的J16/J26/J36系列在體積和重量并沒(méi)有太大變化；
Although the valve trim has become more complicated, our J17 series has not changed much in volume and weight compared with the J16/J26/J36 series of the same specification;
而且我們的三密封復(fù)合閥的三級(jí)密封面都堆焊了STL6/STL12硬質(zhì)合金組合，耐沖刷和腐蝕，使用壽命更長(zhǎng)；
Moreover, the three-stage sealing surface of our three-seal globe valve is surfacing with STL6/STL12 cemented carbide combination, which is resistant to erosion and corrosion and has a longer service life;
口徑：DN20~DN100
壓力等級(jí)：CL150~CL2500
產(chǎn)品特點(diǎn)：
繼承了海特科常規(guī)截止閥高進(jìn)低出和閥籠節(jié)流的特性；
Inherited the characteristics of HITEK standard globe valve high inlet and low outlet and cage throttling;
三級(jí)密封面都堆焊了STL6/STL12硬質(zhì)合金組合，耐磨損，耐沖刷，使用壽命更長(zhǎng)；
Three sealing surfaces are surfacing welded with STL6/STL12 cemented carbide combination, which is resistant to wear and erosion, and has a longer service life;
填料預(yù)緊機(jī)構(gòu)，為填料提供持續(xù)的預(yù)緊力；
Packing pre-tensioning mechanism to provide continuous pre-tensioning force for packing;
手輪螺母采用雙軸承支撐，的減小閥門(mén)啟閉所需的力矩。
Two thrust bearing design to reduce the torque of handwheel operation.
閥門(mén)內(nèi)件采用可更換的閥芯、閥座和閥籠，方便檢修，節(jié)約時(shí)間和成本。
The cage , plug and seat are all replaceable with the valve in line reducing maintenance
costs and down time.
