Ivalve inoluhlu olubanzi lokusetyenziswa kunye neentlobo, ezinokuthi zohlulwe ngokubanzi zibe ziindidi ezimbini:

1. ivelufa ezenzekelayo: ivalve esebenza ngokwayo ngokuxhomekeke kumthamo wendawo (ulwelo kunye negesi).Njenge-valve yokukhangela, i-valve yokukhusela, i-valve yokulawula, i-valve yokudonsa, i-valve yokunciphisa uxinzelelo, njl.

2. ivalve yokuqhuba: ivelufa esebenza nge-manual, umbane, i-hydraulic kunye ne-pneumatic indlela, njenge-valve butterfly, i-valve yebhola, i-valve yesango, i-valve yokumisa, i-valve yencwadi, i-valve yeplagi, njl.

Ngokwendlela yokuqhuba, inokwahlulwa ibe:

1. Umbane: uqhutywa yimoto okanye ezinye izixhobo zombane.

2. Hydraulic: iqhutywa (amanzi, ioli).Uhlobo lwesilayidi sohlobo lwesilayidi

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

4. I-Manual: ngoncedo lwe-handwheel, i-handle, i-lever okanye i-sprocket, iqhutywe ngabasebenzi.Xa i-torque yothumelo inkulu, ixhotyiswe ngezixhobo zokunciphisa isantya njengevili kunye negiya.

Ngokwenjongo, ivalve inokwahlulwa ibe:

1. Umsebenzi wokuqhawula: osetyenziselwa ukudibanisa okanye ukunqumla i-middle pipeline, njenge-valve yokumisa, i-valve yesango, i-valve yebhola, i-valve yaseCambodian, njl.

2. Khangela umsebenzi: isetyenziselwa ukuthintela umva we-medium, njenge-valve yokukhangela.

3. Umsebenzi wokulawula: usetyenziselwa ukulawula uxinzelelo kunye nokuhamba kwe-medium, njenge-valve yokulawula kunye ne-valve yokunciphisa uxinzelelo.

I-4.Umsebenzi wokusabalalisa: isetyenziselwa ukutshintsha i-flow direction of medium and distribution medium, njengeplagi yeendlela ezintathu, i-valve yokusabalalisa, kunye nokucoca.

5. Ivalve yokhuseleko: xa uxinzelelo oluphakathi ludlula ixabiso elichaziweyo, lisetyenziselwa ukukhupha i-redundant medium kunye nokuqinisekisa ukhuseleko lwenkqubo yombhobho kunye nezixhobo, ezifana nevalve yokhuseleko kunye ne-valve yongxamiseko.

6. Amanye amaqela akhethekileyo: njengevalve yokudonsa, ivalve yokukhupha umoya, ivalve yokukhupha, njl.

Wamkelekile ukuba uqhagamshelane nathi ngayo nayiphi na indawo yokuphosa.Sikhangela iindaba zakho nangaliphi na ixesha.

Ndithatha ibhotile yewayini kwaye ndiyokusela phakathi kweentyatyambo.
Sihlala sibathathu -
ndibala isithunzi sam kunye nomhlobo wam inyanga emenyezelayo.
Ngovuyo inyanga ayazi nto yokusela,
nesithunzi sam asinxanwa.
Xa ndicula inyanga ithe cwaka.
Xa ndidanisa, nesithunzi sam siyadanisa.
Emva kwayo yonke imibhiyozo iindwendwe kufuneka zimke;
Olu lusizi andilwazi.
Xa ndigoduka,
inyanga ihamba nam isithunzi sam siyandilandela.
