Darvoza valf:
Darvoza vallari bilan mo'ljallangan a darvoza o'rtasida ikkita o'rindig'idan nazoratga o'tish oqimi suyuqlik. The gate bo'lishi mumkin qo'lda yoki tomonidan an aktuator, va u mo'ljallangan to liq ochiq yoki yopish val bilan a %{90-d}degree aylanishi. Darvoza vallari odatda ishlatiladigan dasturlarda ishlatiladi bu erda a qattiq yopiq off talab qilinadi, masalan ichida neft va gaz sanoati, qaerda ular ishlatiladi to to uchun xom neft va tabiiy gazning oqimini boshqarish.
Toʻp valflar:
To'p vallar foydalanish a to'p bilan a teshik ichida uni boshqarish uchun oqim suyuqlik. The ball 90 daraja to ochiq yoki yopish valve, ularni oson ishlatish va uchun oson qiladi foydalanish va yuqori ishonchli. Ball vana odatda ishlatiladi dasturlarda ishlatiladi bu erda a tez yopiq off talab qilinadi, masalan in the water treatment industry, bu erda ular ishlatiladigan joyda nazorat qilish uchun suv oqimi uchun suv oqimi kerak.
Kelebek valflar:
Kelebek vallar foydalanish a disk o'rnatilgan on a markaziy shaftoli nazorat nazorat uchun suyuqlik oqimi . Disk aylanadi 90 daraja uchun ochiq yoki yopish valve, qaysi ularni oson ishlatish uchun oson qiladi foydalanish uchun ishlatiladi va yuqori samarali. Butterfly valves are odatda ishlatiladi dasturlarda ishlatiladi bu erda a tez yopiq talab qilinadi 2c bunday yilda bo'lgani kabi HVAC sanoati, bu erda ular ishlatiladi ular uchun havo va suvning oqimini boshqarish uchun boshqarish uchun havo va suv.
In summary, the main differences between gate valves, ball valves, and butterfly valves lie in their design and construction, as well as the specific applications they are used for. Gate valves are best suited for applications where a tight shut-off is required, ball valves are ideal for quick shut-off applications, and butterfly valves are well-suited for applications where a quick shut-off is required, and precise control of the flow is not necessary.
