Umahluko phakathi kwevalve yesango yesiqu eNganyukiyo kunye nevalve yesango yesikhondo enyukayo

A ivalve yesangosisetyenziselwa udibaniso oluphakathi kunye nokuvalwa, kodwa hayi kulawulo.Xa kuthelekiswa nezinye iivalve, iivalve zesango zinoluhlu olubanzi lwezicelo ezidibeneyo ngokubhekiselele kuxinzelelo, ioli esebenzayo, uxinzelelo loyilo kunye nobushushu.

Ngokwendawo yomsonto wesiqu sevalve, iivalve yesangoinokwahlulwa ibe yivalve yesango yesiqu esinyukayo kunye nevalve yesango yesiqu enganyukiyo (NRS).

Umahluko omkhulu phakathi kwevalve yesango yesiqu esinyukayo kunye nevalve yesango yesiqu enganyukiyo ngezantsi:

1. Isiqu sesiqu esinyukayoivalve yesangoibhencekile kwaye iyabonwa.

Isiqu sevalve yesango enganyukiyo sikumzimba wevalvu kwaye asibonakali;

2. Ivalve yesango le-Rising stem iqhutywa ngumsonto wesikhondo sevalve kunye nevili lokuqhuba, ngaloo ndlela iqhuba iWedge ukuba iphakame kwaye iwe;

Ivalve yesango lesiqu esinganyukiyo iqhuba i-wedge ukuba iphakame kwaye iwe ngokujikeleza kwesiqu kwindawo esisigxina.Xa utshintsha, ivili lokuqhuba kunye nesiqu se-valve zidibaniswe kunye kwaye zimile.

3. Umsonto wothumelo lwevalve yesango enesiqu esinganyukiyo ibekwe ngaphakathi kumzimba wevalvu.Ngethuba lenkqubo yokuvula nokuvala i-valve, i-stem ijikeleza kuphela kwindawo, kwaye indawo yokuvula kunye nokuvala i-valve ayikwazi ukugwetywa ngamehlo;

Umsonto wokuqhuba kwisiqu sevalve yesango enyukayo utyhilekile ngaphandle komzimba wevalvu, kwaye ukuvuleka kunye nokuvala kunye nendawo yewedge kunokugwetywa ngengqondo;

4. Ubude be-valve yesango ye-stem engavukiyo incinci, kwaye indawo yokufakela incinci;

I-valve yesango lokunyuka kwe-stem inokuphakama okukhulu xa ivuliwe ngokupheleleyo, kwaye idinga indawo enkulu yokufakela;

5. Isiqu sevalve yesango enyukayo singaphandle komzimba wevalve, olungele ukugcinwa kunye nokuthambisa;

Umsonto wesikhondo wevalve yesango ye-stem enganyukiyo ingaphakathi kumzimba wevalve, ekunzima ukuyigcina kunye nokuthambisa, kwaye isiqu sevalve sikhukuliswa lula nguphakathi, kwaye ivelufa yonakala lula.

6. I-stem nut yevalve yesango enyukayo ikwibhonethi okanye isibiyeli.Xa uvula kwaye uvala isango, i-stem nut ijikelezwe ukufikelela ekunyuseni okanye ukuhla kwesiqu.

I-stem nut yevalve yesango yesiqu enganyukiyo ikumzimba wevalvu kwaye idibana ngokuthe ngqo nesiphakathi.Xa uvula kwaye uvala i-valve, ifikelelwa ngokujikeleza i-valve stem.

7. Ukwakhiwa kwe-valve yesango lokunyuka kwe-stem kunenzuzo kwi-lubrication ye-stem, kwaye iqondo lokuvula nokuvala liyabonakala, ngoko lisetyenziswa ngokubanzi.

Ukuphakama kwe-valve yesango ye-stem engavukiyo ihlala ifana, ngoko ke indawo yokufakela incinci, kwaye ifanelekile kwiivalve zesango ezinobubanzi obukhulu okanye indawo yokufakela encinci.Esi sakhiwo kufuneka sixhotyiswe ngesalathisi sokuvula kunye nokuvala ukubonisa iqondo lokuvula nokuvala.
