Zeziphi iintlobo zeevalvu?

ivelufa sisixhobo somatshini esilawula ukuhamba, icala, uxinzelelo, ubushushu, njl. Ivalve licandelo elisisiseko kwinkqubo yombhobho. Ufakelo lwevalvu lufana nobuchwephesha kunye neempompo kwaye zihlala zixoxwa njengodidi olwahlukileyo. Ngoko ke zeziphi iintlobo zeevalvu? Makhe sijonge kunye.

Okwangoku, ezona ndlela zixhaphakileyo zokuhlela iivalvu zamazwe ngamazwe nezasekhaya zezi zilandelayo:

1. Ngokweempawu zolwakhiwo, inokwahlulwa ngokwendlela eshukumayo yelungu elivalayo ngokunxulumene nesihlalo sevalve:

1. Imilo yesango yecandelo: Iqhekeza lokuvala lihamba kumbindi wesitulo sevalve.

2. Ubume besango: Iqhekeza lokuvala lihamba kumbindi wesihlalo sevalve ethe nkqo.

3. Inkuku kunye nebhola: Indawo yokuvala yiplunger okanye ibhola, ejikeleza kumgca ophakathi.

4. Ukumila kwejingi; iqhekeza lokuvala lijikeleza kwi-axis ngaphandle kwesitulo sevalve.

5. Ubume besitya: Idiskhi yelungu elivalayo ijikeleza i-axis kwisihlalo sevalve.

6. Imilo yevalve yesilayidi: Isiqwenga sokuvala sityibilika kwicala elithe ngqo kumjelo.

2. Ngokwendlela yokuqhuba, inokwahlulwa ngokweendlela ezahlukeneyo zokuqhuba:

1. Umbane: Uqhutywa ziinjini okanye ezinye izixhobo zombane.

2. Hydraulic: iqhutywa (amanzi, ioli).

3. Umoya; sebenzisa umoya ocinezelweyo ukuqhuba ivalve ukuvula nokuvala.

4. I-Manual: Ngoncedo lwe-handwheel, i-handle, i-lever okanye i-sprocket, njl., iqhutywe ngabasebenzi, kwaye xa i-torque yokudlulisa ikhulu, ixhotyiswe nge-worm gear, i-gear kunye nezinye izixhobo zokunciphisa.

Ezintathu, ngokwenjongo, ngokweenjongo ezahlukeneyo zevalve inokwahlulwa ibe:

1. Ukwaphuka: isetyenziselwa ukuqhagamshela okanye ukusika imidiya yemibhobho, efana neevalvu zeglowubhu, iivalvu zesango, iivalve zebhola, iivalve zebhabhathane, njl.

I-2, ukusetyenziswa okungabuyiyo: isetyenziselwa ukuthintela i-medium ukuba ingabuyeli ngasemva, njenge-valve yokukhangela.

I-3, ukulungiswa: isetyenziselwa ukulungelelanisa uxinzelelo kunye nokuhamba kwe-medium, njenge-valve yokulawula, i-valve yokunciphisa uxinzelelo.

4. Ukusabalalisa: kusetyenziselwa ukutshintsha indlela yokuhamba kwendlela kunye nokusabalalisa i-medium, njenge-cock yeendlela ezintathu, i-valve yokusabalalisa, i-valve yesilayidi, njl.

5. I-valve yokhuseleko: Xa uxinzelelo lwe-medium ludlula ixabiso elichaziweyo, lisetyenziselwa ukukhupha i-medium engaphezulu ukuqinisekisa ukhuseleko lwenkqubo yokuhambisa imibhobho kunye nezixhobo, ezifana ne-valve yokhuseleko kunye neevalve eziphuthumayo.

6. Ezinye iinjongo ezikhethekileyo: njengemigibe, iivalvu zokukhupha umoya, iivalvu zokukhupha amanzi, njl.
