The hard-sealed butterfly valve is a newly developed long-life, energy-saving butterfly valve by our company. It consists of main components such as the valve body, butterfly disc, sealing ring, and transmission mechanism. Its structure is designed based on the two-dimensional or three-dimensional eccentric principle and features a new manufacturing process that accommodates both elastic and multi-layer hard-soft seals. This design reduces torque during operation, achieving energy efficiency and labor-saving benefits. At the same time, it ensures the valve's overall reliability in corrosion resistance, high temperature tolerance, and wear resistance. Common types of hard-sealed butterfly valves include wafer type, lug type, and flanged type butterfly valves.

上裝式球閥主要用于管道和工業(yè)系統(tǒng)，在傳統(tǒng)全通徑球閥的基礎(chǔ)上具有可以實(shí)現(xiàn)在線維修和減少外漏等優(yōu)點(diǎn)。本產(chǎn)品是一種新型頂入式組合球閥，閥座可在閥體周?chē)惭b和移動(dòng)。通過(guò)螺紋，將閥座的外緣連接到保持圈上。支撐蓋上有彈簧，彈簧安裝在閥體上，擋圈可壓縮彈簧。 所述制造孔位于所述閥座和保持圈的外緣上。本新型產(chǎn)品采用整體設(shè)計(jì)，泄漏可能性小，使用安全，雙重密封。球從頂部安裝，因此無(wú)需拆卸管道即可完成維護(hù)，非常方便。

清管閥一種高性能球閥，專為惡劣的工業(yè)環(huán)境而設(shè)計(jì)，具有多種功能，旨在優(yōu)化管道清潔和維護(hù)。該閥有利于管道清管器的運(yùn)動(dòng)，有效去除水垢、沉積物和其他雜質(zhì)，保持管道的清潔度和流動(dòng)效率。
