Van Bướm Vệ Sinh Là Gì?

Van Bướm Vệ Sinh bằng Thép Không Gỉ là thiết bị điều khiển lưu lượng quay một phần tư vòng được thiết kế cho các đường quy trình vệ sinh. Một đĩa quay mở hoặc đóng đường lưu thông trong 90 độ, cho phép đóng nhanh với độ nhiễu loạn tối thiểu và không có điểm chết. Thiết kế vệ sinh của van bướm loại bỏ các vùng lưu giữ và khe hở nơi vi khuẩn có thể tích tụ.

Định nghĩa & Nguyên lý hoạt động

Thiết kế tâm đường cho phép đĩa ở trục của ống; một vòng quay 90° của trục xoay đĩa song song với dòng chảy (mở) hoặc vuông góc (đóng). Cấu hình lệch tâm — lệch một, hai hoặc ba — giảm mài mòn gioăng và có sẵn theo yêu cầu.

  • Đường lưu thông toàn bộ, không có vùng lưu giữ
  • Không có điểm chết, không có khe hở
  • Thiết kế đĩa tâm đường hoặc lệch tâm

Cấu tạo Van

Thân hai mảnh với đĩa, trục, bạc lót và gioăng làm kín — lắp ráp bằng bu lông và đai ốc. Thân, đĩa và trục có cùng cấp vật liệu (SS304/316L/2205) để nhất quán về điện hóa. Tất cả các van đều tương thích CIP/SIP.

  • Thân + đĩa + trục cùng cấp SS phù hợp
  • Sẵn sàng cho CIP (Vệ sinh tại chỗ) và SIP (Hơi nước tại chỗ)
  • Cần tháo gioăng trục khỏi đường ống để thay thế

Thông số kỹ thuật

Every wholesale sanitary butterfly valve from HEYI is built to international hygienic standards. Below are the core material, seal, and pressure parameters that procurement engineers need for specification and approval.

Body / Disc / Stem Materials

Valve body, disc, and stem share the same stainless steel grade for galvanic consistency. Each SS316L batch undergoes PMI (Positive Material Identification) spectroscopic analysis verifying Cr, Ni, and Mo content before production begins.

Quality Assurance & Certifications

HEYI maintains a closed-loop quality system from raw material intake to final shipment. Every valve is 100% pressure-tested and sealed — no sampling, no exceptions.

Surface Finish & Welding

Standard mechanical polishing (MP) achieves internal surface Ra ≤ 0.8 μm. Custom electrolytic polishing (EP) reaches Ra ≤ 0.4 μm for high-purity pharma applications. TIG and laser welding produce full-penetration seams; laser welds match parent metal microstructure for equivalent corrosion resistance.

  • Integrated spinning forming eliminates internal weld joints
  • TIG + laser welding, narrow seam, deep penetration
  • Bead blasting / shot peening available
  • Endoscope inspection can be arranged per request

3-A / FDA / CE / GMP & MTR Traceability

Products comply with FDA, 3-A, CE, and GMP standards. USP Class VI seals available as an option. Every batch ships with a Material Test Report (MTR) and full lot traceability documentation.

  • SS304/316L raw material: 100% PMI spectroscopic verification
  • MTR + batch number traceability for every shipment
  • USP Class VI seal option for pharma grade

100% Pressure & Sealing Test

Every valve undergoes hydrostatic pressure testing and sealing verification before shipment — 100% full inspection, not sampling. Laboratory tests include spectroscopic analysis, hardness (Vickers/Rockwell), surface roughness, and ultrasonic thickness measurement.

  • Hydrostatic pressure test: 100% coverage
  • Sealing verification: 100% coverage
  • Lab: hardness, roughness, ultrasonic thickness

FDA Compliance Test Reports — Seal Material Verification

Seal gaskets used in HEYI sanitary butterfly valves are independently tested by CIRS and SGS laboratories against US FDA 21 CFR 177.2600 (Rubber Articles Intended for Repeated Use in Food Contact). All extraction results — both aqueous and fatty food simulants — passed with significant safety margins. Full reports available on request.
