Indlela yokugcina yokupakisha ivalvu:

Abagcwalisi bale projekthi ikakhulu baquka ezi zinto zimbini zilandelayo: PTFE kunye negraphite ethambileyo.

Xa igcinwe, itywinwe ebhegini okanye kwibhokisi. Gcina ngokucocekileyo kwindawo eyomileyo nengena umoya, kuphephe ukukhanya kwelanga. Nika ingqalelo ekungeneni komoya ngexesha lokugcinwa kwexesha elide, kwaye ulawule ubushushu bendawo yokugcina ukuba bungadluli kuma-50°C ukuthintela uthuli olugqithisileyo. Ukuba uthuli olufakwe kumphezulu wokuzalisa lususiwe kwaye lusetyenziswe, lusule ngendwangu ecocekileyo.

Indlela yokupakisha iValve endaweni:

Izitywina zokupakisha ziqulunqwe ngolu hlobo lulandelayo: 1). Ukupakisha i-nut yoxinzelelo, i-2) i-Swing bolt, i-3) i-pin esisigxina, i-4) i-packing, i-5) i-sleeve yokupakisha, i-6) Ukupakisha ipleyiti yoxinzelelo (ngamanye amaxesha i-5 kunye ne-6 ngamalungu abalulekileyo ngokwe-mold kunye nokumiselwa kweemeko ezahlukeneyo zokusebenza, umsebenzi wonke. iyafana naleyo yokwahlukana)

Amanyathelo okupakisha okutshintshwa kwetywina ami ngolu hlobo lulandelayo:

1. Sebenzisa i-wrench ukususa i-1) i-nut compression nut kwaye uyiphakamise 5) i-sleeve yokupakisha yokupakisha kunye ne-6) i-plate yokupakisha yokupakisha, ishiya indawo yokusebenza yokutshintsha indawo yokupakisha.

2. Sebenzisa i-screwdriver ye-flat-blade okanye ezinye iziqwenga zetsimbi ukuze ususe ukupakishwa kokuqala kwaye ubeke entsha. Ukuba ukupakisha ukupakisha kusetyenziswe, xa ufaka ukupakisha okutsha, qwa lasela ukuba isalathiso sokunciphisa ukupakisha kufuneka sigxininiswe ngu-90 ~ 180 °, kwaye i-angle edibeneyo kufuneka iphindwe kabini. Musa ukugqithelana izihlandlo ezininzi kwicala elinye njengoko kubonisiwe kumzobo;

3. Emva kokufaka isixa esifanelekileyo sokupakisha, buyisela i-5) i-gland yokupakisha kunye ne-6) ukupakisha ukufakwa kweplate yoxinzelelo. Xa ufaka, qaphela indawo yesitywina sokupakisha kunye ne-6 ~ 10mm enzulu kwi-valve cover (okanye i-1.5 ~ 2 amaxesha obunzima bokupakisha) njengesalathisi sokumisa (Njengoko kuboniswe ngezantsi).

4. Buyisela i-1). Ukupakisha i-nut yoxinzelelo, i-2) Gxininisa indawo yokufakela i-bolt edibeneyo ide ifike kwi-20% yokunyanzeliswa kokupakisha.

5. Emva kokugqiba la manyathelo angentla, yenza uhlolo oluphambili kwi-valve ethathe indawo yokupakisha ekusebenziseni okulandelayo ukuze ubone ukuba kuyimfuneko ukunyusa ukupakisha kwangaphambili.

Amanqaku: Imiyalelo yokuqinisa kwakhona kunye nokutshintshwa kokupakisha phantsi koxinzelelo.

Le misebenzi ilandelayo yimisebenzi enobungozi. Nceda ungawazami kancinci ukuba akukho mfuneko. Nceda ulandele ngokungqongqo olu xwebhu lwesikhokelo ngexesha lamanyathelo okusebenza:

1. Umsebenzisi kufuneka abe nokuqonda okuthile koomatshini kunye neevalvu. Ukongeza kwizixhobo ezifunekayo zomatshini, umqhubi kufuneka anxibe iiglavu ezikhusela ukushisa, izikhuselo zobuso kunye nezigcina-ntloko.

2. Ivalve ivulwe ngokupheleleyo de itywina eliphezulu levalve lisebenze ngokupheleleyo. Isiseko sokugweba sesokuba indlela yokusebenza yevalvu ayinakukwazi ukuphakamisa isikhondo sevalvu, kwaye akukho sandi singaqhelekanga kwisikhondo sevalvu.

3. Umqhubi kufuneka abe kwicala lokupakisha indawo yokutywina okanye ezinye izikhundla ezingenakuqikelelwa. Kuvinjelwe ngokungqongqo ukujongana nendawo yokupakisha. Xa ukupakishwa kufuneka kuqiniswe, sebenzisa i-wrench yokuqinisa i-1) Ukupakisha i-nut yoxinzelelo, i-2 ~ 4 amazinyo, macala omabini e-nut yokupakisha yokupakisha Kufuneka ukuba iqhutywe, kungekhona nje icala elinye.

4. Xa ukupakishwa kufuna ukutshintshwa, sebenzisa i-wrench ukukhulula i-1) Ukupakisha i-nut compression, i-2 ~ 4 amazinyo, i-nut compression nut yokupakisha kumacala omabini kufuneka iqhutywe ngokunye. Ngeli xesha, ukuba kukho impendulo engaqhelekanga kwi-valve stem, yima ngokukhawuleza kwaye usethe kwakhona i-nut, qhubeka Sebenzisa indlela yokusebenza yevalve ngokuhambelana nenkqubo kwisinyathelo sesi-2, gcwalisa isitywina kwi-valve stem de isebenze ngokupheleleyo, kwaye uqhubeke ukubuyisela ukupakisha. Ukupakishwa kokutshintshwa phantsi koxinzelelo akuvumelekanga ukutshintshwa ngokupheleleyo ngaphandle kweemeko ezizodwa. Ubungakanani obutshintshiweyo yi-1/3 yokupakisha iyonke. Ukuba akunakwenzeka ukugweba, iipakethi ezintathu eziphezulu zingatshintshwa. Emva kokuba ufakelo lugqityiwe, buyisela ufakelo lwe-5 yokupakisha umkhono wokushicilela kunye ne-6 yokupakisha ipleyiti yokushicilela. Xa ufaka, qaphela indawo yesitywina sokupakisha kunye ne-6 ~ 10mm enzulu kwi-valve cover (okanye i-1.5 ~ 2 amaxesha ubukhulu bokupakisha) njengesalathisi sokumisa. Buyisela 1). Ukupakisha i-nut yoxinzelelo, i-2) Gxininisa indawo yokufakela i-bolt edibeneyo ukuya kwi-25% yokunyanzeliswa okukhulu kokupakisha. Ukuba akukho kuvuza kupakisho lwesiqu sevalve esezantsi, kugqityiwe. Ukuba kukho ukuvuza, landela iinkqubo kumanyathelo 2 kunye ne-3 ukuqinisa.

5. Onke la manyathelo okusebenza angasentla alungiselelwe kuphela iivalvu zokuphakamisa isiqu ezinyukayo ezifana: ivelufa yesango yesiqu esinyukayo, ivalve yesithintelo esinyukayo, njl. njl., ayisebenzi kwisiqu esimnyama kunye nezinganyusi izivalo ezinje: ivelufa yesango elimnyama, mnyama. Ivalve yokumisa isiqu, ivalve yebhabhathane, iivalve zeBhola njalo njalo.
