The valvechishandiso chinoshandiswa mukufambisira nekudzora gasi uye mvura ine angangoita chiuru chemakore enhoroondo.
Parizvino, mune yepipeline system yemvura, iyo vheji yekudzora ndiyo chinhu chekudzora, uye basa rayo guru nderekuparadzanisa michina uye pombi system, kudzora kuyerera, kudzivirira kuyerera, kutonga uye kuburitsa kumanikidza. Sezvo zvakakosha zvikuru kusarudza iyo yakanyatsokodzera inodzora valve yepipeline system, zvakakoshawo kuti unzwisise maitiro evhavha uye matanho uye hwaro hwekusarudza valve.
Nominal pressure yevhavha
Kudzvinyirirwa kwezita kwevharuvhu kunoreva dhizaini yakapihwa kudzvanywa inoenderana nesimba remuchina wemidziyo yepombi, kureva kuti, ndiyo inobvumidzwa kushanda kwevhavha pane tembiricha yakatarwa, inoenderana nechinhu chevhavha. . Kumanikidza kwekushanda hakuna kufanana, saka, kudzvinyirirwa kwezita ndiro parameter inoenderana nezvinhu zvevhavha uye yakabatana nekushisa kunobvumirwa kushanda uye kushanda kwekushanda kwezvinhu.
A valve inzvimbo iri mukati mepakati circulation system kana pressure system, iyo inoshandiswa kugadzirisa kuyerera kana kumanikidza kwepakati. Mamwe mabasa anosanganisira kudzima kana kubatidza midhiya, kudzora kuyerera, kushandura midhiya inoyerera mafambiro, kudzivirira midhiya kudzoka, uye kudzora kana kuburitsa mhepo.
Aya mabasa anowanikwa nekugadzirisa nzvimbo yevhavha yevhavha. Kugadzirisa uku kunogona kuitwa nemaoko kana otomatiki. Manual kushanda kunosanganisirawo kushanda kwemaoko kudzora drive. Mavharuvhu anoshanda nemaoko anonzi mavharuvhu emaoko. Ivhavha inodzivirira kudzokera shure inonzi check valve; iyo inodzora kumanikidzwa kwekuyamura inonzi valve yekuchengetedza kana vhavha yekudzivirira.
Kusvika ikozvino, iyo indasitiri yevhavha yakakwanisa kuburitsa huwandu hwakazara hwegedhi mavharuvhu, globe mavharuvhu, throttle mavharuvhu, plug mavharuvhu, bhora mavharuvhu, emagetsi mavharuvhu, diaphragm control mavharuvhu, cheki mavharuvhu, kuchengeteka mavharuvhu, kumanikidza kuderedza mavharuvhu, chiutsi misungo uye emergency-kuvhara mavharuvhu. Zvigadzirwa zvevhavha zvezvikamu gumi nezviviri, zvinopfuura mazana matatu emhando, uye zvinopfuura zviuru zvina zvakatemwa; iyo yakanyanya kudzvanywa yekushanda i600MPa, iyo yakanyanya dhayamita yezita i5350mm, yakanyanya tembiricha yekushanda i1200.℃, tembiricha shoma yekushanda ndeye -196℃, uye svikiro rinoshanda iMvura, chiutsi, oiri, gasi rechisikigo, midhiya yakasimba inoodza (senge concentrated nitric acid, medium concentration sulfuric acid, etc.).
Ngwarira kusarudzwa kwevhavha:
1. Kuti uderedze kudzika kweivhu rekuvhara kwepombi,shavishavi vharafuinowanzosarudzirwa pombi yakakura yedhayamita; iyo inonyanya kukanganisa yevhavhavhavhavha ndeyokuti butterfly plate inotora imwe chikamu chemuchinjikwa wemvura, iyo inowedzera kumwe kurasikirwa kwemusoro;
2. Mavharuvhu akajairika anosanganisirabutterfly valves, gedhi mavharuvhu, mavhavha ebhora uye mavhavhavha evhavha, etc. Rudzi rwemavhavha anoshandiswa mumusungo wemvura unofanirwa kufungidzirwa pakusarudza.
3. Kukandira uye kugadzirisa mavharuvhu ebhora uye mavharuvhu epuragi zvakaoma uye zvinodhura, uye zvinowanzokodzera mapaipi madiki uye epakati-dhayamita.

Iyo plug valve inewo mabhenefiti akafanana, asi chikamu chekupfuura-mvura hachisi denderedzwa rakakwana.
4. Kana iine zvishoma pakadzika kwevhu rekuvhara, edza kusarudza gedhi valve; kureba kwevhavha yegedhi yegedhi hombe-dhayamita vertical gedhi vharafu inokanganisa kudzika kwevhu-kufukidza kwepombi, uye kureba kweiyo yakakura-dhayamita yakatwasuka yegedhi vharafu inowedzera nzvimbo yakatwasuka inogarwa nepombi uye inokanganisa kurongeka kwemamwe mapaipi;
5. Mumakore achangopfuura, nekuda kwekuvandudzwa kwekombiyuta yekukanda, kushandiswa kwejecha resin kukanda kunogona kudzivisa kana kuderedza kushandiswa kwemagetsi, nokudaro kuderedza mari, saka kukwanisa kwevhavha yebhora inoshandiswa mumapaipi makuru-diameter inofanirwa kuongorora. Kana iri mutsara wekutema wecaliber size, inofanirwa kutariswa nekugovaniswa zvinoenderana nemamiriro chaiwo.
