Zuva rega rega rekugadzirisa vharafu huru yehunyanzvi hwekuita

Zuva rega rega rekuchengetedza valve main technical performance Daily kuchengetedza 1. Kuchenjerera kunofanira kubhadharwa kune nzvimbo yekuchengetedza yevhavha. Inofanira kuchengetwa muimba yakaoma uye ine mhepo uye yakavharwa kumativi ose emugero. 2, valve inofanira kuongororwa nguva dzose, uye kubvisa tsvina pairi, smear anti-rust mafuta pamusoro payo. 3. Mushure mekuiswa uye kushandiswa kwevhavha, inofanira kugadziriswa nguva dzose kuti ive nechokwadi chekushanda kwayo. 4. Tarisa kana nzvimbo yekuvharisa yevhavha yakasakara uye kugadzirisa kana kuitsiva maererano nemamiriro ezvinhu. 5, tarisa iyo trapezoidal tambo inopfeka yehunde uye stem nati, kana kurongedza kwacho kwapera uye kusashanda, uye ita chinodiwa kutsiva. 6, kuiswa chisimbiso kwevhavha kunofanirwa kuongororwa kuti ive nechokwadi chekuita kwayo. 7. Ivhavha iri kushanda inofanira kunge yakasimba, mabhoti paflange uye bracket akazara, tambo hadzina kukuvara, uye hapana chinosunungura chiitiko. 8, kana vhiri reruoko rikarasika, rinofanira kunge rakagadzirira munguva, uye haigone kutsiviwa neyakagadziriswa wrench. 9. Packing gland haibvumirwi kutsvedza kana pasina preload clearance. 10, kana nharaunda yekushandiswa kwevharuvhu yakanyanya kushata, panjodzi yekunaya, chando, guruva, jecha uye kumwe kusvibiswa kwetsvina, inofanira kuisirwa chivharo chekudzivirira. 11, vharafu pachiyero inofanira kuchengetwa yakakwana, yakarurama, yakajeka, chisimbiso chevhavha, chivharo. 12, insulation bhachi haifanire kudonha, kuputika. 13, mukushanda kwevharuvhu, dzivisa kugogodza pairi, kana kutsigira zvinhu zvinorema, etc. Matanho ekuchenesa Mavhavhavha anofanirwa kupfuura nenzira inotevera musati wasangana: 1, maererano nezvinodiwa zvekugadzirisa, zvimwe zvikamu zvinoda kuita kurapa kwekutsvaira, iyo pamusoro haigone kuve nekugadzirisa burr, nezvimwewo; 2. Nhengo dzese dzakabviswa mafuta; 3, pickling passivation mushure mekudzikisa, yekuchenesa mumiririri haina phosphorus; 4, pickling yakacheneswa nemvura yakachena mushure mekugeza, haigoni kuva nemishonga inosara, carbon steel parts inosiya danho iri; 5, chikamu chimwe nechimwe chine jira risiri rakarukwa rakaoma, harigone kuchengetedza tambo dzemakushe epamusoro, kana nenitrogen yakachena yakaoma; 6. Pukuta zvikamu chimwe nechimwe nemucheka usina kurukwa kana kuti precision sefa bepa rakasvibiswa nedoro rakachena kusvikira pasisina ruvara rwakasviba. Iyo huru tekinoroji mashandiro evhavhavhavha yekuvhara zvikamu zvekugona kudzivirira kubuda kwe media, ndiyo inonyanya kukosha tekinoroji maitiro ezviratidzo zvevhavha. Pane zvikamu zvitatu zvekuisa chisimbiso zvevhavha: kusangana pakati pekuvhura nekuvhara zvikamu uye chigaro chevharuvhu maviri ekuisa chisimbiso pamusoro; Kurongedza uye valve stem uye kurongedza bhokisi rinoenderana; Joint of body to bonnet. Imwe yeaimbova leakage inonzi internal leakage, iyo inowanzonzi yakarembera, inozokanganisa kugona kwevhavha kugura svikiro. Main tekinoroji kuita kwevharuvhu Kutanga, vharafu yekuisa chisimbiso mashandiro Inoreva vharafu yekuisa chisimbiso zvikamu zvekugona kudzivirira kubuda kwe media, ndiyo inonyanya kukosha tekinoroji maitiro ezviratidzo zvevharuvhu. Pane zvikamu zvitatu zvekuisa chisimbiso zvevhavha: kusangana pakati pekuvhura nekuvhara zvikamu uye chigaro chevharuvhu maviri ekuisa chisimbiso pamusoro; Kurongedza uye valve stem uye kurongedza bhokisi rinoenderana; Joint of body to bonnet. Imwe yeaimbova leakage inonzi internal leakage, iyo inowanzonzi yakarembera, inozokanganisa kugona kwevhavha kugura svikiro. Kune kirasi yevhavhavhavhavha, kubuda kwemukati hakubvumirwi. Iwo maviri ekupedzisira kuvuza anonzi kubuda kwekunze, kureva, kubuda kwe media kubva kuvharuvhu kuenda kuvharuvhu kunze. Leakage ichakonzera kurasikirwa kwezvinhu, kusvibiswa kwezvakatipoteredza, zvakakomba zvinokonzeresa tsaona. Kune zvinopisa, zvinoputika, zvine muchetura kana radioactive media, kuvuza hakubvumidzwe, saka vharafu inofanirwa kuve yakavimbika yekuisa chisimbiso. Mbiri, iyo inoyerera yepakati Iyo inoyerera yepakati inoreva yepakati kuburikidza nevharuvhu ichaburitsa kudzvinyirira kurasikirwa (kudzvanywa musiyano pamberi uye mushure mevharuvhu), kureva, vharafu ine kumwe kupikisa kuyerera kwepakati, yepakati kukunda kushorwa. yevharuvhu ichapedza imwe huwandu hwesimba. Kubva pakufunga nezvekuchengetedza simba, dhizaini uye kugadzira mavharuvhu kuti kuderedze kupikisa kwevhavha kumhepo inoyerera zvakanyanya sezvinobvira. Zvitatu, kuvhura nekuvhara simba uye kuvhura nekuvhara nguva Kuvhura nekuvhara simba uye torque ndiwo masimba kana torque dzinofanirwa kuiswa kuvhura kana kuvhara vharafu. Vhara vharuvhu, kudiwa kwekuita iyo yakavhurika-yakavharika chikamu uye kutumira fomu chisimbiso pakati peiyo mbiri yekuisa chisimbiso pamusoro pekumanikidza, asi zvakare kukunda pakati pehunde uye kurongedza, tsinde yevharuvhu uye pakati petambo dze nati, vharafu tsvimbo yekupedzisira inotakura friction uye. zvimwe zvikamu zvesimba rekupokana, uye saka zvinofanirwa kushandisa simba rekuvhara uye nguva yekuvhara, mukuita kwekuvhura nekuvhara, valve inodiwa pakuvhura nekuvhara simba uye yakavhurika-yepedyo torque shanduko, Iyo yakanyanya kukosha iri pamagumo e nguva yakavharwa kana pakutanga kwenguva yakazaruka. Mavharuvhu anofanirwa kugadzirwa uye kugadzirwa kudzikisa simba rekuvhara nekuvhara torque. Yechina, kuvhura nekuvhara kumhanya Kuvhura uye kuvhara nekukurumidza kunoratidzwa senguva inodiwa kupedzisa kuvhura kana kuvhara chiito chevhavha. General vharuvhu kuvhura uye kuvhara kumhanya hakusi kuomesesa zvinodiwa, asi mamwe mamiriro ane zvakakosha zvekuvhura nekuvhara kumhanya, senge zvimwe zvinodiwa zvekuvhura nekukurumidza kana kuvhara, kana tsaona, zvimwe zvinodiwa pakuvhara zvishoma, kana mvura ikarova. iyo inofanirwa kutariswa pakusarudza rudzi rwevhavha. shanu, kunzwisiswa kwekufamba uye kuvimbika Chiito chekunzwa uye kuvimbika kunoreva vharuvhu yepakati parameter shanduko, ita mhinduro inoenderana nechiyero chekunzwa. For throttle valve, pressure reduce valve, regulating valve uye mamwe mavharuvhu anoshandiswa kugadzirisa maparameters epakati pamwe nekuchengetedza vharafu, trap valve uye mamwe mavharuvhu ane chaiwo mabasa, kushanda kwayo senitivity uye kuvimbika kwakakosha zvakanyanya technical performance zviratidzo. Nhanhatu, hupenyu hwebasa Hupenyu hwebasa hunoreva kusimba kwevharuvhu, indekisi yakakosha yekuita yevhavha, uye ine kukosha kukuru kwehupfumi. Kazhinji kuitira kuti uve nechokwadi chekuisa chisimbiso chehuwandu hwenguva dzekutaura, inogonawo kuratidzwa nekushandiswa kwenguva.
