Indlela yokugcina i-valve yokupakisha:

Izigcwalisi zale phrojekthi ikakhulukazi ziqukethe izinto ezimbili ezilandelayo: i-PTFE ne-graphite ethambile.

Uma igcinwe, ivalwe esikhwameni noma ebhokisini. Gcina kahle endaweni eyomile nengena umoya, gwema ukukhanya kwelanga. Naka ukungena komoya ngesikhathi sokugcina isikhathi eside, futhi ulawule izinga lokushisa lendawo yokugcina lingeqi ku-50°C ukuze uvimbele uthuli oluningi. Uma uthuli olufakwe ebusweni bokugcwalisa lususwa futhi lusetshenziswe, lusule ngendwangu ehlanzekile.

Indlela yokufaka esikhundleni sokupakisha i-valve:

Izimpawu zokupakisha zakhiwe kanje: 1). Ukupakisha inati lokucindezela, 2) Ibhawodi lokujiya, 3) Iphinikhodi egxilile, 4) Ukupakisha, 5) Umkhono wokupakisha, 6) Ipuleti lokupakisha lokucindezela (kwesinye isikhathi u-5 no-6 kuyizingxenye ezibalulekile ngokuya ngesikhunta futhi Inqunywa izimo zokusebenza ezihlukene, umsebenzi wonke kuyafana nokuhlukana)

Izinyathelo zokubuyisela uphawu lokupakisha zimi kanje:

1. Sebenzisa isikrufu ukuze ususe 1) inathi lokucindezela lokupakisha bese uliphakamisa 5) umkhono wokucindezela ukupakisha kanye 6) nepuleti lokucindezela lokupakisha, ushiye isikhala sokusebenza kokushintsha ukupakisha.

2. Sebenzisa i-screwdriver ene-flat-blade noma ezinye izingcezu zensimbi ukuze ususe ukupakisha kwangempela bese ufaka okusha. Uma kusetshenziswa ukupakisha ukupakisha, lapho ufaka ukupakisha okusha, qaphela ukuthi isiqondiso sokusikeka kokupakisha kufanele sinyakaze ngo-90 ~ 180 °, futhi i-engeli efakiwe kufanele iphindwe ngababili. Ungabi nokugqagqana okuningi ohlangothini olufanayo njengoba kukhonjisiwe emfanekisweni;

3. Ngemva kokufaka inani elifanele lokupakisha, buyisela 5) indlala yokupakisha kanye 6) nokufakwa kwepuleti lokucindezela. Lapho ufaka, naka indawo yophawu lokupakisha kanye no-6 ~ 10mm ekujuleni kwesembozo se-valve (noma izikhathi ezingu-1.5 ~ 2 ubukhulu bokupakisha) njengereferensi yokumisa (Njengoba kuboniswe ngezansi).

4. Buyisela 1). I-packing compression nut, i-2) Qinisa indawo yokufaka ye-joint bolt ize ifinyelele ku-20% wokucindezela ukupakisha.

5. Ngemva kokuqeda izinyathelo ezingenhla, yenza ukuhlola okubalulekile ku-valve ethathe indawo yokupakisha ekusetshenzisweni okulandelayo ukuze ubone ukuthi kudingekile yini ukwandisa ukulayishwa kwangaphambili kokupakisha.

Amazwana: Imiyalelo yokuqinisa kabusha nokushintshwa kokupakisha ngaphansi kwengcindezi.

Le misebenzi elandelayo iyimisebenzi eyingozi. Sicela ungawazami kancane uma kungenasidingo. Sicela ulandele ngokuqinile le dokhumenti yomhlahlandlela phakathi nezinyathelo zokusebenza:

1. Umsebenzisi kufanele abe nokuqonda okuthile ngemishini namavalvu. Ngaphezu kwamathuluzi emishini adingekayo, umqhubi kufanele agqoke amagilavu ​​avimbela ukushisa, izihlangu zobuso nezigqoko.

2. I-valve ivuleka ngokugcwele kuze kube yilapho uphawu olungaphezulu lwe-valve lusebenza ngokugcwele. Isisekelo sokwahlulela siwukuthi indlela yokusebenza ye-valve ayikwazi ukuphakamisa isiqu se-valve, futhi awukho umsindo ongajwayelekile esiqwini se-valve.

3. U-opharetha kufanele abe ngasohlangothini lwendawo yokupakisha uphawu noma ezinye izikhundla ezingakwazi ukuvezwa. Kuvinjelwe ngokuphelele ukubhekana nesimo sokupakisha. Lapho ukupakisha kudinga ukuqiniswa, sebenzisa i-wrench ukuze uqinise 1) I-packing compression nut, amazinyo angu-2 ~ 4, izinhlangothi zombili ze-nati yokucindezela ukupakisha Idinga ukubulawa, hhayi nje uhlangothi olulodwa.

4. Uma ukupakisha kudinga ukushintshwa, sebenzisa isikrufu ukuze ukhulule 1) I-packing compression nut, amazinyo angu-2 ~ 4, i-packing compression nut ezinhlangothini zombili idinga ukubulawa ngokushintshana. Ngalesi sikhathi, uma kukhona ukusabela okungavamile okuvela esiqwini se-valve, yima ngokushesha futhi usethe kabusha inati, qhubeka Sebenzisa indlela yokusebenza ye-valve ngokuhambisana nenqubo esesinyathelweni sesi-2, qedela uphawu esiqwini se-valve kuze kube yilapho sesisebenza ngokugcwele, futhi uqhubeke nokufaka esikhundleni sokupakisha. Ukupakisha esikhundleni ngaphansi kwengcindezi akuvunyelwe ukushintshwa ngokuphelele ngaphandle kwezimo ezikhethekile. Inani elishintshwayo lingu-1/3 wesamba sokupakishwa. Uma kungenakwenzeka ukwahlulela, amaphakethe amathathu aphezulu angashintshwa. Ngemuva kokuthi ukufakwa sekuqediwe, buyisela ukufakwa komkhono wokucindezela wokupakisha ongu-5 kanye nepuleti lokucindezela lokupakisha elingu-6. Lapho ufaka, naka indawo yophawu lokupakisha kanye no-6 ~ 10mm ekujuleni kwesembozo sevalvu (noma izikhathi ezingu-1.5 ~ 2 ubukhulu bokupakisha) njengereferensi yokuma. Buyisela 1). I-packing compression nut, i-2) Qinisa indawo yokufaka yebhawudi elihlanganyelwe ku-25% wokucindezelwa okuphezulu kokupakisha. Uma kungekho ukuvuza ekupakisheni kwesiqu se-valve engezansi, kuqedile. Uma kukhona ukuvuza, landela izinqubo ezinyathelweni zesi-2 no-3 ukuze uqinise.

5. Zonke lezi zinyathelo zokusebenza ezingenhla ngezezivimbo zokuphakamisa isiqu ezikhuphukayo kuphela njengalezi: i-valve yesango lesiqu esikhuphukayo, i-valve ye-stem stop ekhuphukayo, njll., ayisebenzi esiqwini esimnyama kanye nama-valve esiqu angaphakamisi njengalezi: i-valve yesango lesiqu esimnyama, mnyama i-stem stop valve, i-butterfly valve, i-Ball valves njalonjalo.
