ສະ ໝັກ ຂະ ໜາດ ກາງແລະເງື່ອນໄຂການເຮັດວຽກຂອງວາວຜີເສື້ອ

ວາວວາວສ່ວນໃຫຍ່ແມ່ນໃຊ້ ສຳ ລັບແຫຼວ, ອາຍແກັສທໍ່ຄວາມດັນຕ່ ຳ ຂະ ໜາດ ເສັ້ນຜ່າກາງຂະ ໜາດ ໃຫຍ່. ມັນ ເໝາະ ສົມກັບໂອກາດທີ່ຄວາມຕ້ອງການການສູນເສຍຄວາມກົດດັນບໍ່ສູງ, ລະບຽບການໄຫຼວຽນແມ່ນມີຄວາມ ຈຳ ເປັນ, ແລະຄວາມຕ້ອງການເປີດແລະປິດກໍ່ໄວ; ໂດຍທົ່ວໄປອຸນຫະພູມຕໍ່າກວ່າ 300 â„ ƒແລະຄວາມກົດດັນຕໍ່າກວ່າ 40 ກລ). ໂດຍທົ່ວໄປແມ່ນໃຊ້ນ້ ຳ ແລະອາຍແກັສ, ແລະຄວາມຕ້ອງການໃນລະດັບກາງບໍ່ສູງ. ສື່ກາງຍັງສາມາດ ນຳ ໃຊ້ໄດ້.

1) ສື່ທີ່ວ່າvalve butterflyສາມາດຂົນສົ່ງແລະຄວບຄຸມແມ່ນນ້ ຳ, ປensອງ, ກະແສນ້ ຳ ທີ່ໄຫຼອອກ, ນ້ ຳ ເປື້ອນ, ນ້ ຳ ທະເລ, ອາກາດ, ແກgasດ, ອາຍແກັສ ທຳ ມະຊາດແຫຼວ, ຜົງແຫ້ງ, ແປ້ງ, ໝາກ ໄມ້ແລະປະສົມກັບທາດລະລາຍທີ່ຖືກໂຈະ.
2) ໂດຍປົກກະຕິແລ້ວ, ໃນການປັ່ນປ່ວນ, ການຄວບຄຸມການຄວບຄຸມແລະຂະ ໜາດ ກາງຕົມ, ຄວາມຍາວຂອງໂຄງສ້າງສັ້ນແລະຄວາມໄວໃນການເປີດແລະປິດ (1/4 ລ້ຽວ) ແມ່ນມີຄວາມ ຈຳ ເປັນ. ການຕັດຄວາມກົດດັນຕ່ ຳ (ຄວາມແຕກຕ່າງຂອງຄວາມກົດດັນຕ່ ຳ),valve butterflyແມ່ນແນະນໍາໃຫ້.
3) ວາວວາວ can be used in double position adjustment, necking channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere and abrasive medium.
4) When the valve butterfly is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special valve butterfly with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric valve butterfly is suitable for bidirectional opening and closing and adjustment of ventilation and dust removal pipeline, and is widely used in gas pipeline and water channel of metallurgy, light industry, electric power and petrochemical system.
6) Metal to metal wire sealed double eccentric valve butterfly is suitable for urban heating, gas supply, water supply and other gas, oil, acid and alkali pipelines, as a regulating and throttling device.
7) Metal to metal face sealed triple eccentric valve butterfly is not only used as program control valve of large PSA gas separation unit, but also widely used in petroleum, petrochemical, chemical, metallurgical, electric power and other fields. It is a good substitute for gate valve and stop valve.

MST valve butterfly is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil, various acid and alkali and other pipelines which require complete sealing, zero leakage in gas test, high service lie and working temperature from - 10 ℃ to 150 ℃.
