橡膠密封刀閘閥
Knife Gate Valve Rubber Seal
是一種可更換橡膠密封圈的刀閘閥結(jié)構(gòu),密封原理主要是通過閘板與橡膠密封圈的緊靠,從而達(dá)到密封效果,此結(jié)構(gòu)主要特點在于,橡膠密封圈是封套在閥座上的階梯凹槽內(nèi),密封圈由金屬壓套反鎖,使得密封圈與閘板開關(guān)密封過程中不會脫落,并且密封圈壞了,可以取下金屬壓套隨意更換橡膠密封圈。使得閥門使用效率大大提高。是一種經(jīng)濟有效的高性能產(chǎn)品。
It's an changeable rubber ring knife gate valves. Seal principle mainly through the gate and rubber seals close to achieve the sealing effect .The main features of this structure is that the rubber ring is in the seat on the envelope ladder groove, the seal is locked by metal pressing sets , making ring sealing will not switch off when processing, and if the seals broken, you can remove the metal press kits replace the rubber ring at random,which improves the valve efficiency greatly . It's a cost-effective, high-performance products.
