Izindlela zokufaka kanye nokwenza imfihlo zezibhola valves

Kunezinto ezimbili zezibhola: izibhola zokuphepha ngaphansi kwezindlela ezimbili. Okokuqala kukhona isilinganiso, uma kubhekwa ngaphansi, ukuphepha phansi kwesikhathi esiphezulu akukwazi kuhlonishwa, okwesibili akukwazi ukwenzeka. Isakhiwo sisezindlela ezimbili nokuphepha okwesibili: isakhiwo sokuphepha ngaphansi kunezidingo zokuphela, isakhiwo sokuphepha okwesibili kunezidingo zokuphela. Sicela uqale ngezindlela zokufaka izibhola zokuphepha ngaphansi.

Izikhala zebhola zokufaka:

Ngaphambi kokusebenza, kumele uthumele ukuthi ipayipilini kanye nesivalo sivuselelwe.

I-Valve actuator ikusebenza ngokwenzeka kwe-signal yokungena ekhethekileyo ukuze isuke ishaye isikhala: uma ishaye isuke ishaye 1/4 ukugeza (900), ishaye isungeza. Uma ishaye isuke ishaye 1/4 ukugeza (900), ishaye isiphakamisa.

3. Uma isikhombisa sokuthi isikhundla sikaqinisekisi siphendule ekwele, isivalo siphakamisa; uma isikhombisa isikhathi esisodwa kwezindlela, isivalo siphuma.

Iziko yokwenza imveliso ye-ball valve:

Isikhathi eside kakhulu sokuphila kanye nokugcina okungenamathuba kuzoba kusho ngamathathu: ukugcina isimo esiphilayo/sokuphila okuphelele kanye nokwenzeka okuhambisana nokuthuthukiswa okuphelele.

Lapho ibhola valve liqashwe, isitsha somthamo sihamba phansi ekhishini le-valve.

Ngaphambi kokwenza ukunakekela, sula isipho sezinto zomphakathi futhi uthinte i-valve ekwenzeni isimo esiphakathi.

Phinda uxhasa umdwebo noma isuplai sekhanda ngaphambi kokwenza ukunakekela.

Susa isitshudeni sokwenza isicubu phambi kokwenza okunakekelwa.

Isicelo sokugcina

Uma kukhona isiphuzo esincane ekupheleni kwezindlela zokuphakama, kumele kube khishwe i-stem nut.

Ukufuna: Ungakhokheli, kubonakala ukukhokhela iringi eli-1/4 kuya ku-iringi eli-1 kuzosiza ukususa.

Thatha isiteji sethi nesikhiye kanye nemibhobho.

I. Ukulahlekelwa

Vula ivalvu ekhanda nesiphakathi esisodwa futhi ushintsha izinto ezimbi ezitholakala kwi-valvu noma ngaphandle kwayo.

Vala i-valvu yebhola, nceda izinkuni kanye nemikhuba kusuka kwezinye iziflange, futhi suqeda kabusha i-valvu kusuka kwezindlela zokupheka.

Susa i-actuator-actuator, i-bracket yokuhlanganisa, i-check washer, i-stem nut, i-butterfly spring plate, i-Genan, i-wear plate kanye ne-stem packing ngalesi sithupha.

Susa izinkuni nezinkuni zokubeka isicelo somzimba, hlanganisa isicelo kusuka kumzimba futhi susa isicelo sokugcina.

Sicela sicela ukuthi ibhola lihlanganiswe ekupheleni ukuze kube lula ukulondoloza kuye ekupheleni, ngemuva kwalokho, nquma isite.

Hlukanisa isithwala ngaphansi kwezinkinobho ezindawo zokupheka kwevalvu kuya kufika ekupheleni, khona ke sula i-o-ring kanye ne-packing ring.

Qaphela ukuthi ungakwazi ukubhaka isiqandisi esiphethwe kakhulu kanye nokugqoka isiphakathi sevalvu.

ukulungisa

Kuyacacile ukuthi izigqoko nezilonda zesiqhelo kufanele zibadlale ngamasevisi okuthengiswa.

Hlanganisa ngaphansi kwesimo sokuhlukanisa nokuhlanganisa.

Izindlela zokulungisa izinkuni zokulungisa ezithintekile.

Izinkuni zokugcina ezithintekile.

Emva kokufaka isitshizi, hambisa isithende ukuze ususe isipholi ukuze ususe isayini esisiza ukuvula nokufaka isivalo.
