Kodi pali kusiyana kotani pakati pa ma valves aku America ndi ma standard a Germany ndi ma standard valves apadziko lonse?

(Muyezo waku America, muyezo waku Germany, muyezo wapadziko lonse) kusiyana pakati pamagetsi:

Choyamba, kuchokera pamtundu woyenera wa dziko lililonse ukhoza kusiyanitsidwa: GB ndiye muyezo wadziko lonse, muyezo waku America (ANSI), muyezo waku Germany (DIN). Kachiwiri, mutha kusiyanitsa ndi mtunduwo, mtundu wa valavu wapadziko lonse umatchulidwa molingana ndi zilembo za pinyin za gulu la ma valve. Mwachitsanzo, valavu yachitetezo ndi A, valavu ya gulugufe D, valavu ya diaphragm G, yang'anani valavu H, valavu yapadziko lonse J, valavu Yampweya L, valavu P, valavu ya mpira Q, msampha S, valavu yampata Z ndi zina zotero.

Palibe chodziwika pakati pa valavu yaku America, valavu yaku Germany, valavu yadziko, palibe china koma kusiyanitsa pakati pa magwiridwe antchito ndi kuthamanga, zotengera za valavu ndi zinthu zamkati ndizosavuta kunena, osangoti chitsulo choponyedwa, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, etc. American Standard, mwachitsanzo, kuyambira 125LB mpaka 2,500 lb (kapena 200PSI mpaka 6,000 psi). API yayikuluyo, ANSI, imadziwika kuti API, mavavu a ANSI. Kupanikizika kwama valve aku Germany nthawi zambiri kumakhala PN10 ku PN320, pogwiritsa ntchito DIN muyezo; Ngati valavu yathyoledwa, gwiritsani ntchito muyezo wolumikizana. Miyezo yayikulu yapadziko lonse lapansi ndi American standard petroleum association API standard, American standard standard ANSI, Germany standard DIN, Japan standard JIS, GB, European standard EN, Britain standard BS.

Mwachidule, ma valves aku America adapangidwa, amapangidwa, amapangidwa ndikuyesedwa molingana ndi miyezo yaku America. Ma valve wamba aku Germany adapangidwa, kupangidwa, kupangidwa ndikuyesedwa malinga ndi miyezo yaku Germany. Muyezo National vavu ndi, malinga ndi kamangidwe China muyezo, kupanga, kupanga, kudziwika mavavu.

Kusiyanitsa pakati pa atatuwa ndi pafupifupi: 1, muyezo wa flange si wofanana; 2, kutalika kwa kapangidwe kake ndi kosiyana; 3. Zomwe oyang'anira amafunikira ndizosiyana.

Valavu yaku America yokhazikika, valavu yachijeremani yokhazikika, valavu yadziko lonse asanayikidwe amafunika kuyendera ma valve ndikuwunika, kuti awonetsetse kugwiritsidwa ntchito, komanso kugwira ntchito yabwino pachitetezo cha chitetezo ntchito. Kupanikizika koyezetsa kudzakhala kuthamanga kwambiri pantchito, kukakamiza kotsikitsitsa komanso kuthamanga kotsika kwambiri. Kuchita mozama komanso kusatuluka kwa nthunzi kumayesedwa ngati oyenerera.

American standard standard valve test standard: is 1.5 times the pressure pressure, the time time is 5min, the test time of the valve body is not broken, no deformation, the valve does not leak water, the pressure gauge does not drop as oyenerera. Pambuyo poyesedwa kwamphamvu, mayeso oyeserera amachitikanso. Kupsyinjika kwa mayeso ndikofanana ndi kukakamiza mwadzina. Valve ilibe kutayikira panthawi yoyesa, ndipo kuyeza kwapanikizika sikumatsika kuti kuyenerereke.
