Ukuba usathandabuza ukuba ukhethe iivalvu zesango lentsimbi eyenziwe ngomgunyathi okanye iivalvu zesango lentsimbi eyenziwe ngomgunyathi (WCB), nceda ujonge i-zfa valve factory ukuze wazise umahluko omkhulu phakathi kwazo.

1. Ukubumba nokubumba ziindlela ezimbini ezahlukeneyo zokucubungula.

Ukubumba: Isinyithi siyafudunyezwa size sinyibilike size sigalelwe kwisikhunta sesanti okanye kwisikhunta. Emva kokuba sipholile, siyaqina sibe yinto ethile. Imingxunya yomoya iveliswa lula embindini wemveliso.
Ukubumba: Ngokuyintloko kusetyenziswa iindlela ezifana nokubethela kwiqondo lobushushu eliphezulu ukwenza isinyithi sibe yinto yokusebenza enobume nobukhulu obuthile kwimeko yeplastiki, kunye nokutshintsha iimpawu zayo zomzimba.

2. Umahluko ekusebenzeni phakathi kweevalvu zesango ezenziwe ngobuqili kunyeIivalvu zesango leWCB

Ngexesha lokubumba, isinyithi siyaguqulwa sibe yiplastiki, nto leyo enefuthe lokucokisa iinkozo, ngoko ke sisetyenziswa rhoqo ekuveliseni iindawo ezibalulekileyo ezingenanto. Ukubumba kuneemfuno zezinto eziza kucutshungulwa. Ngokubanzi, isinyithi esityhidiweyo, i-aluminium, njl.njl. zineempawu ezingcono zokubumba. Ukubumba akunazo iingenelo ezininzi zokubumba, kodwa kunokuvelisa iindawo ezineemilo ezintsonkothileyo, ngoko ke kudla ngokusetyenziswa ekuveliseni iindawo ezingenanto ezixhasayo ezingadingi zixhobo ziphezulu.

2.1 Uxinzelelo

Ngenxa yokwahluka kweempawu zezinto eziphathekayo, iivalvu zentsimbi ezibunjiweyo zinokumelana namandla amakhulu okubetha, kwaye ukuqina kwazo, ubulukhuni kunye nezinye iimpawu zoomatshini ziphezulu kunezo zeIivalvu zeWCB. Ke ngoko, ingasetyenziswa kwiimeko zokusebenza ezixinzelelweyo eziphezulu. Amanqanaba oxinzelelo asetyenziswa rhoqo kwiivalvu zentsimbi ezibunjiweyo zezi: PN100; PN160; PN250; PN320; PN400, 1000LB~4500LB. Uxinzelelo oluqhelekileyo olusetyenziswa kwiivalvu zeWCB zezi: PN16, PN25, PN40, 150LB~800LB.

2.2 Ububanzi begama

Ngenxa yokuba inkqubo yokubumba ineemfuno eziphezulu kwiimolds nakwizixhobo, ububanzi beevalvu ezibumbayo buhlala bungaphantsi kwe-DN50.

2.3 Amandla okulwa nokuvuza

Xa kumiselwa yinkqubo ngokwayo, ukuphoswa kwe-cast kunokubangela umngxuma ngexesha lokucubungula. Ke ngoko, xa kuthelekiswa nenkqubo yokuphoswa kwe-cast, amandla okuthintela ukuvuza kwe-cast valves awalingani nalawo e-forged valves.
Ke ngoko, kwamanye amashishini aneemfuno eziphezulu zokuthintela ukuvuza, njengegesi, igesi yendalo, ipetroli, iikhemikhali kunye namanye amashishini, iivalvu zentsimbi ezibunjiweyo zisetyenziswa kakhulu.

2.4 Inkangeleko

Iivalvu zeWCB kunye neevalvu zentsimbi ezixonxiweyo kulula ukuzibona ngenkangeleko. Ngokubanzi, iivalvu zeWCB zinombala wesilivere, ngelixa iivalvu zentsimbi ezixonxiweyo zinombala omnyama.

3. Umahluko kwiinkalo zesicelo

Ukukhethwa okukhethekileyo kweevalvu zeWCB kunye neevalvu zentsimbi ezixonxiweyo kuxhomekeke kwindawo yokusebenza. Akunakwenziwa ngokubanzi ukuba zeziphi iindawo ezisebenzisa iivalvu zentsimbi ezixonxiweyo kunye nokuba zeziphi iindawo ezisebenzisa iivalvu zeWCB. Ukukhethwa kufuneka kusekelwe kwindawo yokusebenza ethile. Ngokubanzi, iivalvu zeWCB azixhathisi i-asidi kunye ne-alkali kwaye zingasetyenziswa kuphela kwimibhobho eqhelekileyo, ngelixa iivalvu zentsimbi ezixonxiweyo zinokumelana noxinzelelo oluphezulu kwaye zingasetyenziswa kwezinye iifektri ezinamaqondo obushushu aphezulu, njengezityalo zamandla kunye nezityalo zeekhemikhali. Ivalvu yeklasi.

4. Ixabiso

Ngokubanzi, ixabiso leevalvu zentsimbi ezibunjiweyo liphezulu kuneleevalvu zeWCB.
