Valfli po'lat nima?

 

Valve po'lat issiqlikka chidamli po'latning muhim tarmog'idir, bu ichki yonish dvigatelini qabul qilish va sadoqatli maxsus materiallar ishlab chiqarishdir. Ushbu material ko'pincha 450 ~ 900 daraja yuqori haroratda va 3000 ~ 7000 ~ 7000 ~ 7000 dan 7000000 gacha bo'lgan bosim va boshqa gaz yuqori haroratli korroziyani va valfning bo'shlig'ini aylanib chiqing. Shu sababli, eng yuqori ish haroratidagi valfe materiallari etarli issiq qarshilik, yuqori haroratli korroziyalarga chidamliligi, oksidlanishga chidamliligi, qarshilikka chidamlilik va ta'sir qarshiga ega bo'lishi kerak.

 

Valvli po'lat po'lat (gaz klapan po'lat; va klapan po'lat) po'latdan foydalangan holda, shuningdek, gaz klapan po'latlari (gazli po'lat) sifatida tanilgan po'latdan foydalangan holda turli xil valmalarni ishlab chiqarish uchun mos keladi. Qiyqonchilikka chidamliligi va korroziya qarshiligini oshirish maqsadida u alyuminiy va sirt volfram yuzasini o'zgartirishni davolash bo'lishi mumkin.

 

Valvli po'latning tasnifi qanday (gaz valvali po'lat; valf po'lat)?

 

Valve po'latining asosiy tasnifi
Valfli po'latlar ikkita asosiy toifaga bo'linadi :qirit va azenit. Ushbu ikki xil valvanning har biri o'ziga xos xususiyatlari va dasturiy stsenariylariga ega.

 

Rabzitik valf po'lat
Xususiyatlar:Yuqori haroratli haroratda yuqori harorat va og'irlik, yaxshi ish, yaxshilik, qarshilikka qarshilik, oksidlanishga chidamliligi va korroziya qarshiligi.


Arizalar:Asosan benzin va dizel dvigatellari uchun iste'mol va egzoz klapanlari ishlab chiqarishda ishlatiladi va dvigatellar4.
Ko'p ishlatiladigan materiallar: masalan, 1cr9si2 va 1cre110si2mo po'latlari, balki kerakli mexanik xususiyatlarni ta'minlaydi, balki sirtni modifikatsiyasini davolash va sektsiyalangan karbinlarning sirtini tayyorlash va sekareya va sekareykalarning sirtini yanada yaxshilaydi.
Ostenitik valfli po'lat
Ostenitik Valve po'latlari ularning a'lo darajadagi va vinoblanishi bilan tanilgan va keng tarmoq muhiti uchun mos keladi.

Qal'a po'latlarini tasniflashning boshqa usullari
Kimyoviy tarkibi asosida tasniflashga qo'shimcha ravishda, valfli po'latlarning tuzilishi ularning tuzilishi va foydalanishiga ko'ra batafsilroq tasniflanishi mumkin:

 

Tuzilish va foydalanish bo'yicha tasniflash
Kesilgan sinf klapanlari: masalan, darvesh kabinalari, asosan, asosan gaz quvuridagi muhitni ulash yoki kesish uchun ishlatiladi.
Sinfli klapanlar: O'rta orquchtirishning oldini olish uchun ishlatiladigan chek klapanlar kabi.
Xavfsizlik klapanlari: masalan, uskunalar va tizimlarni haddan tashqari xavf-xatarlardan himoya qilish uchun ishlatiladigan xavfsizlik klapanlar.
O'rta bosim, oqim va boshqa parametrlarni o'zgartirish uchun ishlatiladigan gazle va tazyiqlarni tartibga solish klapanlar va bosimni kamaytiradigan klapanlar kabi tartibga solish klapanlari.
O'tkir sinf klapanlari: masalan, tarqatish klapanlari, uch tomonlama klapanlar, tuzoqlar, tarqatish, tarqatish yoki gazni quvurga aralashtirish uchun ishlatiladi.
Maxsus maqsadlar: masalan, quvurlarni tozalash klapanlari, shamollatish klapanlari, drenaj klapanlari, drenaj klapanlari, egzoz klapanlari va boshqalar uchun, ma'lum bir sanoat jarayonlari5.

 

Nominal bosimni tasniflashga ko'ra
Vakuum klapan: ishchi bosim bilan ishlaydigan klapanlar atmosfera bosimiga qaraganda past.
Bosimning past valfi 1,6 mba5 dan kam yoki teng bo'lgan nominal bosimli klapanlar.
O'rta bosimli va valf: Nominal bosimli pn 2.5mpa, 4. {3}} MPa, 6.4mpa5.
Yuqori bosimli valf: 1 {2}}. 0 MPa ~ 80.0005.
Ultra-yuqori bosimli valf: Nominal bosimli pn 1 0 0 0 0 {} }5 dan katta yoki teng klapanlar.

 

Haydash rejimida tasniflanadi
Avtomatik valf: Valvli harakatni amalga oshirish uchun vositaning o'z kuchiga ishoning.
Elektr yoki elektrlalar, masalan elektr klapan, pnevmatik klapanlar, gidravlik klapanlar5.
Qo'lda valf: Qabul qilingan va valf harakatini boshqarish uchun qo'lda, tutqichlar, tutqichlar va boshqalar.

Umumiy valf po'latining mexanik xususiyatlari

 

TENTILE kuch: Bu pog'onani yirtizarga qarshi turadi. Turli xil valfli po'latlarning keskinligi turli xil talablarga ega. Masalan, ASTM A105, Otalar uchun umumiy uglerod po'lat zavodi odatda 485 va 620 MPa orasida keskinlik kuchiga ega.

 

Kuch berish: Bu po'lat pog'onani past deformatsiya boshlagan stress. Hosildorlik valfning xavfsizligi uchun kuch sarflaydi. Masalan, WCB odatda 200 va 230 MPa oralig'ida hosildorlik kuchi bilan ishlatiladigan valevılmali po'latdir.

 

Abonquatsiya: Bu uning asl uzunligiga chizilganidan oldin po'latning maksimal uzayishi nisbati. Uzluklanish po'latning plastik xususiyatlarini aks ettiradi. Umuman olganda, ko'tarilish qanchalik baland bo'lsa, po'latning pozitsiyasi shunchalik yuqori bo'ladi. Masalan, A105 ARTMning uzluksizligi odatda 20% va 35%.

 

Qattiqlik: bu po'lat qanchalik yumshoq yoki qattiqligi o'lchovidir. Qattiqlik qanchalik baland bo'lsa, po'latning kiyishi va siqish kuchi yaxshiroq. Masalan, WCBning qattiqligi odatda 20 dan 25 gacha.

 

 

20 yil davomida Xitoyda etakchi klapan ishlab chiqaruvchilar va etkazib beruvchilar sifatida biz sizni zavodimizdan Xitoyda ishlab chiqarilgan valfli po'latdan sotib olishingizni samimiy kutib olamiz. Barcha mahsulotlar yuqori sifatli va raqobatbardosh narxga ega.
