Isikhokelo esincinci sokugcinwa kwevalvu imihla ngemihla

IivalvuAzisetyenziswa kakhulu kumashishini ahlukeneyo kuphela, kodwa zikwasetyenziswa nakwiindawo ezahlukeneyo, kwaye ezinye iivalvu kwiindawo zokusebenza ezinzima zinokuba neengxaki. Ekubeni iivalvu zizixhobo ezibalulekileyo, ingakumbi kwezinye iivalvu ezinkulu, kunzima ukuzilungisa okanye ukuzitshintsha xa kukho ingxaki. Ke ngoko, kubaluleke kakhulu ukwenza umsebenzi olungileyo wokulungisa nokulungisa imihla ngemihla. Makhe sijonge amanye amacebiso malunga nokugcinwa kweevalvu.

 

1. Ukugcinwa kunye nokuhlolwa kwemihla ngemihla kweiivalvu

 

1. Ivalvu mayigcinwe kwigumbi elomileyo nelinomoya, kwaye zombini iziphelo zendlela kufuneka zivalwe.

 

2. IivalvuEzigcinwe ixesha elide kufuneka zihlolwe rhoqo, ukungcola kufuneka kususwe, kwaye ioyile yokulwa nomhlwa kufuneka igqunywe kumphezulu wokucubungula.

 

3. Emva kokufakelwa, kufuneka kwenziwe uhlolo oluqhelekileyo, kwaye izinto eziphambili zokuhlola zezi:

 

(1) Ukuguguleka komphezulu wokuvala.

 

(2) Ukuguguleka kwentambo ye-trapezoidal yesiqu kunye ne-stem nut.

 

(3) Nokuba isizalisi siphelelwe lixesha kwaye asisebenzi, ukuba sonakele, kufuneka sitshintshwe ngexesha.

 

(4) Emva kokuba ivalvu ilungisiwe yaza yahlanganiswa, kufuneka kwenziwe uvavanyo lokusebenza kokutywina.

 

2. Umsebenzi wokulungisa xa ivalvu itshisiwe

 

Ukugcinwa kobuchwephesha kweivalvuNgaphambi nasemva kokuwelda kunye nokuveliswa kudlala indima ebalulekileyo ekukhonzeni ivalvu kwimveliso nasekusebenzeni kwayo, kwaye ulondolozo oluchanekileyo nolucwangcisiweyo nolusebenzayo luya kuyikhusela ivalvu, lwenze ivalvu isebenze ngendlela eqhelekileyo kwaye lwandise ubomi benkonzo yevalvu. Ukugcinwa kwevalvu kunokubonakala kulula, kodwa akunjalo. Kukho iinkalo zomsebenzi ezisoloko zingajongwa.

 

1. Xa ivalvu itshisiwe, ingxaki yokutshizwa kwegrisi idla ngokungananzwa. Emva kokuba isibhamu sokutshizwa kwegrisi sigcwalisiwe, umqhubi ukhetha ivalvu kunye nendlela yokudibanisa igrisi ukuze enze umsebenzi wokutshizwa kwegrisi. Kukho iimeko ezimbini: kwelinye icala, ubungakanani bokutshizwa kwegrisi buncinci, ukutshizwa kwegrisi akwanelanga, kwaye umphezulu wokutshizwa udlaka ngokukhawuleza ngenxa yokunqongophala kwegrisi. Kwelinye icala, ukutshizwa kwegrisi kakhulu kubangela inkunkuma. Oku kungenxa yokuba akukho kubalwa ngokuchanekileyo kwamandla okutshizwa kweevalvu ezahlukeneyo ngokohlobo lwevalvu. Amandla okutshizwa angabalwa ngokobungakanani kunye nohlobo lwevalvu, kwaye emva koko ubungakanani obufanelekileyo begrisi bunokufakwa ngokufanelekileyo.

 

Okwesibini, xa ivalvu itshizwa igrisi, ingxaki yoxinzelelo idla ngokunganakwa. Ngexesha lokusebenza kwe-grease injection, uxinzelelo lwe-grease injection lutshintsha rhoqo kwiincopho nakwiintlambo. Uxinzelelo luphantsi kakhulu, ukuvuza okanye ukungaphumeleli kwe-seal kuphezulu kakhulu, i-grease injection port ivaliwe, i-grease kwi-seal iqinisiwe, okanye iringi yokuvala itshixiwe ngebhola yevalvu kunye nepleyiti yevalvu. Ngokwesiqhelo, xa uxinzelelo lwe-grease injection luphantsi kakhulu, i-grease efakwe i-injection ingena kakhulu ezantsi kwe-valve cavity, eyenzeka rhoqo kwiivalvu ezincinci zesango. Ukuba uxinzelelo lwe-grease injection luphezulu kakhulu, kwelinye icala, jonga i-grease injection nozzle, kwaye uyitshintshe ukuba umngxuma we-grease uvaliwe; Kwelinye icala, ukuqina kwe-grease, apho isisombululo sokucoca sisetyenziswa ukuthambisa ngokuphindaphindiweyo i-grease engasebenziyo kwaye uyitshintshe nge-grease entsha. Ukongeza, uhlobo lwe-sealing kunye nezinto zokuvala nazo zichaphazela uxinzelelo lwe-grease, iintlobo ezahlukeneyo zokuvala zinoxinzelelo lwe-grease olwahlukileyo, ngokubanzi, uxinzelelo lwe-grease inseal oluqinileyo luphezulu kune-grease ethambileyo.

 

Ukwenza lo msebenzi ungasentla kukholelwa ukuba luncedo kakhulu ekwandiseni ubomi benkonzo yeivalvu, kwaye kwangaxeshanye, kunokunciphisa iingxaki ezininzi ezingeyomfuneko.
