1 Mapoinzi akakosha ekusarudza vharafu

1.1 Rondedzera chinangwa chevhavha mumidziyo kana mudziyo

Sarudza mamiriro ekushanda evhavha: chimiro chepakati inoshandiswa, kushanda kwekushanda, kupisa kwekushanda uye maitiro ekugadzirisa maitiro, nezvimwewo;

1.2 Kusarudzwa kwakarurama kwerudzi rwevharuvhu

Chinodiwa chekusarudzwa kwakaringana kwerudzi rwevharuvhu ndechekuti mugadziri anonzwisisa zvizere maitiro ese ekugadzira uye maitiro ekushanda.Apo vagadziri vanosarudza marudzi evhavha, vanofanira kutanga vanzwisisa maitiro ekugadzirisa uye kushanda kwevhavha yega yega;

1.3 Sarudza nzira yekumisa vharafu

Pakati pezvinongedzo zvakabatanidzwa, flange zvinongedzo, uye welded end connections, maviri ekutanga ndiwo anonyanya kushandiswa.Mavharuvhu ane threadari kunyanya mavharuvhu ane dhayamita rezita risingasviki 50mm.Kana iyo dhayamita yakakura kwazvo, zvichave zvakaoma kwazvo kuisa uye kuvhara kubatana.Flange yekubatanidza mavharuvhu ari nyore kuisa uye disassemble, asi akakura uye anodhura kupfuura mavharuvhu akarukwa, saka akakodzera kubatanidzwa kwepombi dzemadhayamita epombi akasiyana uye kumanikidza.Welded connections akakodzera kurema mitoro mamiriro uye akavimbika kupfuura flange kubatana.Zvisinei, zvakaoma kuparadzanisa uye kudzorera mavharuvhu ane welded, saka kushandiswa kwavo kunogumira kumamiriro ezvinhu apo ivo vanogona kazhinji kushanda zvakavimbika kwenguva yakareba, kana apo mamiriro ekushanda akaoma uye kutonhora kwakakwirira;

1.4 Kusarudzwa kwezvinhu zvevharuvhu

Pakusarudza zvinhu zveimba yevhavhavha, zvikamu zvemukati uye zvisimbiso zvechisimbiso, kunze kwekutarisa zvinhu zvemuviri (tembiricha, kudzvanywa) uye makemikari zvinhu (corrosiveness) yesvikiro rekushanda, kuchena kwepakati (kuvapo kana kusavapo kwezvimedu zvakasimba. ) inofanirawo kufungwa nezvayo.Uye zvakare, iwe unofanirwa zvakare kutarisa kune yakakodzera mitemo yenyika uye nedhipatimendi revashandisi.Kwakaringana uye zvine musoro kusarudzwa kwezvinhu zvevharuvhu zvinogona kuve nechokwadi chehupfumi hwehupenyu hwesevhisi uye kuita kwakanyanya kwevhavha.The valve body material selection sequence is: cast iron-carbon steel-stainless steel, and the sealing ring material selection sequence is: rubber-copper-alloy steel-F4;

1.5 Zvimwe

Mukuwedzera, chiyero chekuyerera uye chiyero chekumanikidza kwemvura inoyerera kuburikidza nevhavha inofanira kugadziriswa uye vheji yakakodzera yakasarudzwa uchishandisa ruzivo rwuripo (zvakadai sevhavha chigadzirwa catalogs, valve product samples, nezvimwewo).

2 Nhanganyaya kumavharuvhu anowanzo shandiswa

Kune marudzi akawanda emavharuvhu, kusanganisira gedhi mavharuvhu, globe mavharuvhu, throttle mavharuvhu, shavishavi mavharuvhu, plug mavharuvhu, bhora mavharuvhu, emagetsi mavharuvhu, diaphragm mavharuvhu, cheki mavharuvhu, kuchengeteka mavharuvhu, kumanikidza kuderedza mavharuvhu, misungo uye nechimbichimbi kuvhara-kure mavharuvhu, pakati pezvinowanzo shandiswa Pane mavharuvhu emagedhi, mavharuvhu epasi, mavharuvhu anotsikisa, mavharuvhu epuragi, mavharuvhu eshavishavi, mavharuvhu ebhora, mavharuvhu echeki, mavharuvhu ediaphragm, nezvimwewo.

2.1Gedhi vharafu

Varuvhu (gedhi) zvinoreva vharuvhu ine muviri wekuvhura nekuvhara (vharuvhu ndiro) inofambiswa nedzinde revharuvhu uye inofamba ichikwira nekudzika ichitevedza nzvimbo yakavharika yechigaro chevharuvhu kuti ibatane kana kucheka gwara remvura.Kuenzaniswa nemavharuvhu ekumisa, mavharuvhu egedhi ane kuita zvirinani kuvhara, kushomeka kwemvura, kushomeka kwekuedza kuvhura nekuvhara, uye kuve nekumwe kugadzirisa kuita.Ndiyo imwe yeanonyanya kushandiswa mavharuvhu ekumisa.Izvo zvisingabatsiri ndezvokuti yakakura muhukuru uye yakanyanya kuoma mukugadzirisa kupfuura valve yekumisa.Iyo yekuisa chisimbiso iri nyore kupfeka uye yakaoma kuchengetedza, saka kazhinji haina kukodzera kupuruzira.Zvinoenderana nenzvimbo yeshinda pahunde yevharuvhu yevharuvhu yegedhi, yakakamurwa kuita zvikamu zviviri: yakavhurika stem mhando uye yakavanzwa stem mhando.Zvinoenderana nehunhu hwegedhi, inogona kukamurwa kuita mhando mbiri: wedge mhando uye parallel mhando.

2.2Stop valve

Gorobhu ivharuvhu inovhara ichidzika pasi.Zvikamu zvekuvhura nekuvhara (mavharuvha discs) anofambiswa netsinga yevharuvhu kuti aende kumusoro uye pasi pamwe neaxis yechigaro chevharuvhu (sealing surface).Zvichienzaniswa nemavharuvhu emagedhi, ane mashandiro akanaka ekugadzirisa, kusasimba kwekuvhara, chimiro chakareruka, kugadzira nekugadzirisa zviri nyore, kuramba kwemvura yakakura, uye mutengo wakachipa.Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharwe,inowanzo shandiswa mumapaipi epakati nediki dhayamita.

2.3 Bhora vharafu

Chikamu chekuvhura nekuvhara chevhavha yebhora ibhora rine denderedzwa kuburikidza neburi.Bhora rinotenderera nedzinde revharuvhu kuvhura nekuvhara vharuvhu.Ivhavha yebhora ine chimiro chakareruka, kuvhura nekukurumidza nekuvhara, kushanda nyore, diki diki, uremu huremu, mashoma mashoma, kushomeka kwemvura, kuvharika kwakanaka uye nyore kugadzirisa.
