BS 1868 ndeyeBritish Standard inotsanangura zvinodikanwa zvesimbi cheki mavharuvhu kana asingadzose mavharuvhu ane zvigaro zvesimbi kuti zvishandiswe mumaindasitiri akadai sepetroleum, petrochemical, uye akabatana maindasitiri. Iyi chiyero inovhara zviyero, kudzvanywa-tembiricha zviyero, zvishandiso, uye zvinodiwa zvekuyedzwa zveswing cheki mavharuvhu.Muchirevo cheiyo swing cheki vharafu inogadzirwa zvinoenderana neBS 1868, ichagadzirirwa kuzadzisa iwo chaiwo dimensional uye maitiro ekuita anotsanangurwa mu standard. Izvi zvinovimbisa kuti valve inogona kunyatsodzivirira kudzoka shure uye inosangana nekuchengetedzwa kwakakodzera uye mararamiro ehutano hwekushandiswa kwayo. Zvimwe zvezvinhu zvakakosha zve swing check valve inogadzirwa kuBS 1868 mitemo inogona kusanganisira chivharo chakavharidzirwa, zvindori zvechigaro zvinodzorerwa, uye swing. - mhando disc. Aya mavharuvhu anowanzo shandiswa mukutsikirira uye kudziya kwepamusoro-kupisa uko kudzivirira kuyerera kunokosha.Kana uine mibvunzo yakananga nezve swing cheki vharafu inogadzirwa kune BS 1868 miyero kana kuti inoda rumwe ruzivo nezve yayo yakatarwa, zvinhu, kana kuyedza zvinodiwa, ndapota. ndizivise, uye ndingafara kubatsira mberi.
1. Muviri wevhavhavha uye chivharo chevhavha yekubatanidza fomu: Kirasi150 ~ Kirasi600 uchishandisa chivharo chevhavhavhavha; Kirasi900 kusvika Kirasi2500 inotora yekuzvimanikidza yekuvharisa chisimbiso chivharo.
2. Kuvhura nekuvhara zvikamu (valve disc) dhizaini: dhisiki yevharuvhu yakagadzirwa semhando yekuzunguza, ine simba rakakwana uye kuoma, uye chisimbiso chepamusoro chevharuvha disc chinogona kunge chiri pamusoro pekuisa goridhe zvinhu kana inlaid isiri-simbi zvinhu zvinoenderana nemushandisi. zvinodiwa.
3. Vavhavha inovhara yepakati gasket yakajairika fomu: Kirasi150 cheki vharafu uchishandisa Stainless simbi graphite composite gasket; C|ass300 cheki vharafu nesimbi isina tsvina graphite ronda gasket; Kirasi600 cheki vharafu inogona kushandiswa Stainless simbi ibwe 4. Ingi inomonereka gasket inogonawo kushandiswa simbi mhete gasket; Iyo Kirasi900 kune Kirasi2500 cheki mavharuvhu anoshandisa ega-kumanikidza kuvhara mhete dzesimbi.
5. Fomu yekushanda: Chengetedza valve inovhura kana kuvhara maererano nemamiriro ekuyerera kwepakati.
6. Rocker design: The rocker ine simba rakakwana, rusununguko rwakakwana rwekuvhara diski yevhavha, uye yakashongedzerwa nemudziyo wekudzivirira kudzivirira nzvimbo yekuvhura kubva pakakwirira kuti ivhare.
7. Kusimudza mhete yekugadzira: Ivhavha yakakura-caliber cheki yakagadzirwa nemhete yekusimudza uye chigadziro chekutsigira, iyo yakanakira kusimudza.
Munguva yekuvhura nekuvhara nzira yesimbi yakaumbwa yeglobe valve, nekuti kukweshera pakati pe disc uye yekuvharisa pamusoro pemuviri wevharuvhu idiki pane iyo yevhavha yegedhi, haibatike.
Kuvhura kana kuvhara kwevhavha hunde ipfupi, uye ine yakavimbika kwazvo yekucheka-kubvisa basa, uye nekuti shanduko yevhavha chigaro chechiteshi inoenderana nekurohwa kwevhavha disc, yakakodzera kwazvo kugadzirisa. yehuwandu hwekuyerera. Naizvozvo, rudzi urwu rwevharuvhu rwakanyatsokodzera kucheka-kubvisa kana kudzora uye throttling.
