Tsanangudzo yakadzama yenzira chaiyo yekushandisa valve

Kugadzirira kusati kwaitwa

Usati washandisa valve, unofanira kuverenga mirayiridzo yekushanda zvakanyatsonaka. Usati washanda, iwe unofanirwa kuve wakajeka pamusoro pekuyerera kwegwaro regesi, iwe unofanirwa kuterera kutarisa kuvhura kwevhavha uye kuvhara zviratidzo. Tarisa kutaridzika kwevhavha kuti uone kana vharafu iri kunyorova, kana paine unyoro kuve uchiomesa kurapwa; kana zvikaonekwa kuti pane mamwe matambudziko anofanirwa kugadziriswa nenguva, hazvizoshandiswe nekutadza. Kana iyo valve yemagetsi isiri kushanda kwemwedzi inopfuura 3, clutch inofanira kuongororwa isati yatanga, iva nechokwadi chokuti mubato uri panzvimbo yekunyora, uye wozotarisa kuvhara, kutungamirira uye magetsi emagetsi emotokari.

Kushanda Kwakakodzera Kwemavharuvhu eBhuku

Mavharuvhu eManual ndiwo mavharuvhu anoshandiswa zvakanyanya, uye mavhiri emaoko kana mabatiro akagadzirwa zvinoenderana nesimba revanhuwo zvavo, tichifunga nezvesimba rekuisa chisimbiso uye inodiwa yekuvhara simba. Naizvozvo, haugone kushandisa refu refu kana ruoko rurefu kufambisa ndiro. Vamwe vanhu vakajaira kushandiswa kweplate ruoko, vanofanira kunyatsoteerera kuvhurwa kwevharuvhu kunofanira kushandiswa kumanikidza kutsetseka, kudzivirira simba rakawandisa, zvichikonzera kuvhurwa nekuvhara kwevhavha, simba rinofanira kunge rakatsetseka, kwete kukanganisa. . Kumwe kuvhurika nekuvharwa kwe-high-pressure valve components kwave kunzi kukanganiswa uku uye mavharuvhu akajairwa haakwanise kuenzana neGang.

Kana vharuvhu yakazaruka zvakakwana, handwheel inofanira kupindurwa zvishoma, kuitira kuti tambo pakati pesimba, kuitira kuti irege kusunungura kukanganisa. Forinosimuka stem gedhi mavharuvhu,kurangarira yakavhurika zvizere uye yakavharwa zvakazara kana hunde chinzvimbo, kudzivirira kuvhurika zvizere kana kukanganisa kwenzvimbo yakafa. Uye zviri nyore kutarisa kana zviri zvakajairika kana yakavharwa zvizere. Kana hofisi yevharuvhu yakadzimwa, kana chisimbiso chespool chakadzikwa pakati pemarara makuru, nzvimbo yakavharwa yehunde inofanira kuchinjwa. Kukuvadzwa kwevharuvhu yekuisa chisimbiso pamusoro kana valve handwheel.

Chiratidzo chakazaruka chevhavha: vharafu yebhora,concentric butterfly valve, plug valve stem top surface groove parallel kune chiteshi, zvichiratidza kuti vharafu iri munzvimbo yakazaruka zvakakwana; apo hunde yevharuvhu yakatenderera 90 ° kuruboshwe kana kurudyi, groove iri perpendicular kune chiteshi, zvichiratidza kuti vharafu iri munzvimbo yakavharwa zvakakwana. Mamwe mavharuvhu ebhora, mavharuvhu eshavishavi, mavharuvhu okuvharira ku wrench uye chiteshi chakafanana kuti avhure, akamira kuti avharwe. Nzira nhatu, mavharuvhu mana anofanirwa kushandiswa zvinoenderana nekumaka kwekuvhura, kuvhara uye kudzosera kumashure. Mushure mekuvhiyiwa kwapera, mubato unotakurika unofanirwa kubviswa.

Kushanda kwakarurama kwecheki mavharuvhu

Kuti udzivise simba repamusoro rakagadzirwa panguva yekuvhararabha akagara cheki vharafu, chivharo chinofanira kuvharwa nokukurumidza, nokudaro kudzivirira kuumbwa kwemashure makuru ekudzoka shure, iyo ndiyo inokonzera kukanganisa kunokonzera kuumbwa kwevhavha yakavharwa kamwe kamwe. Nokudaro, kukurumidza kwekuvhara kwevhavha kunofanira kufananidzwa nenzira yakarurama nehuwandu hwekuora kwepakati pemvura yakadzika.

Kana kukurumidza kwepakati inoyerera ichisiyana pamusoro pehupamhi, iyo shoma yekuyerera velocity haina kukwana kumanikidza kuvhara chinhu kuti chimire zvakatsiga. Muchiitiko ichi, kufamba kwechinhu chekuvhara kunogona kunyoroveswa mukati mehumwe huwandu hwekurohwa kwayo. Kukurumidza kudengenyeka kwechinhu chinovhara kunogona kuita kuti zvikamu zvinofamba zvevharuvhu zvisakara nekukurumidza, zvichikonzera kutadza kwevhavha nguva isati yakwana. Kana iyo yepakati iri pulsating, kukurumidza kudengenyeka kwechinhu chekuvhara kunokonzerwawo nekukanganiswa kwakanyanya kwepakati. Pose pazvinenge zviri izvo, cheki mavharuvhu anofanirwa kunge ari uko kukanganiswa kwepakati kunoderedzwa.
