• Yooj yim installation: Cov xov me me yuav tsum muaj kev sib hloov tsawg dua thaum lub sijhawm teeb tsa, ua haujlwm yooj yim dua.

Feem ntau hauv Asia, tshwj xeeb tshaj yog Nyiv, Taiwan, thiab Tuam Tshoj.

Daim ntaub ntawv: Pneumatic Cheebtsam, dej fittings, gas systems.

3. G Xov – BSPP

G Xov belongs rau Whitworth xov series. Nws yog tus qauv zoo heev, thiab qhov ntau thiab tsawg ntawm xov yog feem ntau qhia hauv ntiv tes (xws li 1/4, 1/2, 1/8). G xov nta ib qho yooj yim tsim thiab muaj ntau ntau yam.

Txuj: ISO 228
Lub kaum sab xis: 55 degree
Xov hom: Parallel (Cylindrical)
Unit: Inch

Nta:

High Standardization: Unified thread parameters thiab cov cim ua rau kev sib txuas lus thiab kev sib txuam ntau dua.

Kev teeb tsa ceev: Cov qauv tsim yooj yim tso cai rau kev sib dhos yooj yim thiab disassembly yam tsis xav tau cov cuab yeej nyuaj, txuag lub sijhawm.

Kev sib txuas ruaj khov: Cov xov nruj sib koom ua tau zoo tiv thaiv tensile thiab shear quab yuam, tiv thaiv loosening.

Feem ntau siv hauv Tebchaws Europe thiab thoob ntiaj teb hauv kev ntsuas.

Daim ntaub ntawv: Instrumentation, valve fittings, lub tsev thiab engineering systems.

4. R Xov - ISO Tapered Xov (Zoo li BSPT)

R xov yog ib hom xov uas siv dav rau kev sib txuas tshuab. Piv nrog rau daim duab peb sab threads, nws muaj ib tug smoother profile, uas tso cai rau kom muaj ntau yam load faib.

Txuj: ISO 7-1

Nta:

• High Precision: Zoo heev qhov tseeb thiab geometric kam rau ua kom cov xov zoo.
• Yooj Yim Structure: Muaj ib txoj hlua khi thiab lub tes tsho, ua kom yooj yim rau kev siv.
• Strong Versatility: Muaj nyob rau hauv ntau yam tshwj xeeb kom tau raws li ntau hom kev xav tau.

Feem ntau siv thoob ntiaj teb.

Daim ntaub ntawv: mechanical manufacturing, precision instruments, thiab aerospace applications, qhov twg interchangeability thiab siab precision yog qhov tseem ceeb.

5. M Xov (Metric Xov)

M threads, tseem hu ua metric threads, yog cov feem ntau siv hom metric ntsia hlau xov. Lawv ua raws li tus qauv pitch system teem nyob rau hauv ib tug lej lej. Qhov ntau thiab tsawg yog qhia hauv millimeters - piv txwv li, M6 × 1 qhia txog 6 hli txoj kab uas hla nrog 1 hli suab.
