Ukuhlelwa kweValve

Ivalve ye-TWSngumvelisi wevalvu yobungcali. Kwintsimi yeevalvu iye yaphuhliswa ngaphezu kweminyaka engama-20. Namhlanje, iValve ye-TWS ingathanda ukwazisa ngokufutshane ulwahlulo lweevalvu.

1. Ukuhlelwa komsebenzi kunye nokusetyenziswa

(1) ivelufa yeglowubhu: ivalve yeglowubhu ekwabizwa ngokuba ivelufa evaliweyo, umsebenzi wayo kukudibanisa okanye ukusika okuphakathi kumbhobho. Iklasi yevalve yokusika ibandakanya ivalve yesango, ivalve yokumisa, ivalve yeplagi yevalve ejikelezayo, ivalve yebhola, ivalve yebhabhathane kunye nevalve yediaphragm, njl.

(2)khangela ivalve: ivalve yokukhangela, eyaziwa ngokuba yi-valve yokukhangela enye okanye i-valve yokukhangela, umsebenzi wayo kukuthintela okuphakathi kwi-backflow yombhobho. Ivalve esezantsi yempompo yempompo ikwayeyeklasi yevalvu yokutshekisha.

(3) Ivalve yokhuseleko: indima yesivalo sokhuseleko kukuthintela uxinzelelo oluphakathi kumbhobho okanye isixhobo ekugqithiseni ixabiso elichaziweyo, ukuze kuphunyezwe injongo yokhuseleko lokhuseleko.

(4) ivalve yokulawula: ivalve yokulawula ibandakanya ivalve yokulawula, ivalve ye-throttle kunye nevalve yokunciphisa uxinzelelo, umsebenzi wayo kukulungelelanisa uxinzelelo, ukuhamba kunye nezinye iiparamitha zendlela.

(5) ivelufa ye-shunt: ivelufa ye-shunt ibandakanya zonke iintlobo zeevalvu zokuhambisa kunye neevalvu, njl. njl., indima yayo kukusasaza, ukwahlula okanye ukuxuba okuphakathi kumbhobho.

(6)ivalve yokukhupha umoya: i-valve yokukhupha i-valve iyinxalenye ebalulekileyo yokuncedisa kwi-system yepayipi, esetyenziswa ngokubanzi kwibhoyili, i-air conditioning, i-oyile kunye negesi yendalo, ukunikezelwa kwamanzi kunye nombhobho wokuhambisa amanzi. Ihlala ifakwe kwindawo yokuyalela okanye engqinibeni, njl., Ukuphelisa igesi engaphezulu kumbhobho, ukuphucula ukusebenza kakuhle kwendlela yombhobho kunye nokunciphisa ukusetyenziswa kwamandla.

2. Ukuhlelwa ngoxinzelelo oluncinci

(2) Ivalve yobushushu obuphantsi: isetyenziselwa ubushushu obuphakathi bokusebenza-100℃ t-29℃ ivelufa.

(3) Ivalve yobushushu eqhelekileyo: isetyenziselwa ubushushu obuphakathi bokusebenza-29℃

(4) Ivalve yobushushu obuphakathi: isetyenziselwa ubushushu obuphakathi bokusebenza kwe-120℃ t 425℃ ivalve

(5) Ivalve yobushushu obuphezulu: yevalve enobushushu obuphakathi bokusebenza t> 450℃.

4. Ukuhlelwa ngokwendlela yokuqhuba

(1) Isivalo esizisebenzelayo sibhekisa kwivalve engadingi mandla angaphandle ukuze iqhube, kodwa ixhomekeke kumandla omthombo ngokwawo ukwenza isivalo sihambe. Njengevalve yokhuseleko, ivalve yokunciphisa uxinzelelo, ivalve yokudonsa, ivalve yokukhangela, ivalve yokulawula ngokuzenzekelayo, njl.

(2) Ivalve yokuqhuba amandla: Ivalve yokuqhuba amandla inokuqhutywa yimithombo eyahlukeneyo yamandla.

(3) Ivalve yombane: ivalve eqhutywa ngamandla ombane.

Ivalve yepneumatic: Ivalve eqhutywa ngumoya ocinezelweyo.

ivelufa elawulwa yioyile: ivalve eqhutywa luxinzelelo lolwelo olufana neoyile.

Ukongeza, kukho indibaniselwano yeendlela ezininzi zokuqhuba ezingentla, ezinjengeevalvu zegesi zombane.

(4) Ivalve ye-Manual: ivalve yesandla ngoncedo lwevili lesandla, umqheba, i-lever, i-sprocket, ukuya ngesenzo sevalve. Xa umzuzu wokuvula ivalve mkhulu, eli vili kunye nesinciphisi sevili leentshulube zinokusetwa phakathi kwevili lesandla kunye nesikhondo sevalve. Ukuba kuyimfuneko, ungasebenzisa kwakhona i-universal joint kunye ne-drive shaft yokusebenza umgama omde.

5. Ukuhlelwa ngokwedayamitha yegama

(1) Ivalve yedayamitha encinci: ivalve enedayamitha ye-DN 40mm.

(2)Phakathiivelufa yobubanzi: ivalve enedayamitha ye-DN ye-50 ~ 300mm. ivalve

(3)EnkuluIvalve yedayamitha: ivalve ebizwa ngokuba yi-DN yi-350 ~ 1200mm ivelufa.
