Ndeupi musiyano uripo pakati pemaAmerican standard valves nemaGerman standard uye yenyika standard mavhavha?

(American mureza, chiGerman chiyero, nyika muyero) mutsauko pakati pemavharuvhu:

Chekutanga pane zvese, kubva kune yakajairwa kodhi yenyika yega yega inogona kusiyaniswa: GB ndiyo yenyika muyero, American mureza (ANSI), chiGerman chiyero (DIN). Kechipiri, iwe unogona kusiyanisa kubva kune iyo modhi, iyo yenyika yakajairwa vharuvhu modhi inonzi yakatumidzwa zvinoenderana nematsamba epinyin echikamu chevhavha. Semuenzaniso, iyo yekuchengetedza vharuvhu ndeye A, shavishavi vharuvhu D, diaphragm vharuvhu G, tarisa vharuvhu H, vharuvhu vharuvhu J, throttle vharafu L, sewage vharafu P, bhora vharafu Q, musungo S, gedhi vharafu Z zvichingodaro.

Iko hakuna kusarudzika kwakatarwa pakati peAmerican standard vharafu, chiGerman vharuvhu vharuvhu, yenyika yakajairika vharuvhu, hapana chimwe chinopfuura mutsauko uripakati pekugadzira muyero uye nehuremu hwekumanikidza, iyo vharuvhu muviri zvinhu uye zvemukati zvinhu zviri nyore kutaura, hapana chimwe chinopfuura kukanda simbi, simbi yakakandwa, simbi isina chinhu, nezvimwewo American Standard, semuenzaniso, zvinobva pa125LB kusvika ku2,500 lb (kana 200PSI kusvika 6,000 psi). Iyo huru standard API, ANSI, inowanzozivikanwa seAPI, ANSI mavharuvhu. ChiGerman standard vharuvhu kumanikidza kazhinji PN10 kusvika PN320, uchishandisa DIN standard; Kana iyo vharafu iri flanged, shandisa inoenderana flange standard. Iwo epasi makuru vharuvhu zviyero ndezveAmerican standard petroleum Association API standard, American yenyika standard ANSI, German standard DIN, Japanese standard JIS, GB, European standard EN, British standard BS.

Zvichingotaura, maAmerican standard mavhavha akagadzirwa, akagadzirwa, akagadzirwa uye akaedzwa zvinoenderana nemaAmerican zviyero. MaGerman mavharuvhu akagadzirwa, akagadzirwa, akagadzirwa uye akaedzwa zvinoenderana nematanho eGerman. National vharafu vharafu iri, zvinoenderana neyakajairika dhizaini yekugadzira, kugadzira, kugadzira, kuona kwevhavha.

Musiyano uripo pakati pezvitatu uyu wakaenzana: 1, chiyero cheflange hachina kufanana; 2, kureba kwechimiro kwakasiyana; 3. Izvo zvinodiwa pakuongorora zvakasiyana.

American vharafu vharuvhu, chiGerman standard vharafu, yenyika yakajairwa vharafu isati yaiswa inoda kuita inodiwa vharuvhu kuongorora uye bvunzo basa, kuitira kuona zvakajairika kushandiswa mune inoshanda mamiriro, asi zvakare kuita basa rakanaka pane chengetedzo yedziviriro shanda. Iko kumanikidza kwekuyedza ndiko kuchave kwakanyanya kushanda kumanikidza, kwakaderera kushanda kumanikidza uye kwakaderera kushanda kumanikidzwa zvichiteerana. Kuita kwakapfava uye kusabvaruka hwemhepo kunoonekwa sevanokodzera.

American standard vharuvhu yekuyera muyero muyero: iri 1.5 nguva yakadomwa kumanikidza, iyo bvunzo nguva ndeye 5min, iyo bvunzo nguva yemuviri wevharuvhu haina kutyorwa, hapana deformation, vharuvhu haidonhedze mvura, iyo yekumanikidza gauge haina kudonha seyakakodzera. Mushure mekuedzwa kwesimba kukwenenzvera, bvunzo yekusimba inoitwa zvakare. Iko kusimba bvunzo kumanikidza kwakaenzana neyakaremerwa zita. Ivhavha yacho haina kana leakage panguva yekuyedza, uye iyo yekumanikidza geji haina kudonha kuti ive inokodzera.
