Ukuhlelwa kwevalve

I. Ngokwamandla

1. Ivalve ezenzekelayo: ithembele kumandla ngokwawo ukuze isebenze ivalve.Njengevalve yokukhangela, ivalve yokunciphisa uxinzelelo, ivalve yomgibe, ivalve yokhuseleko, njalo njalo.

2. I-valve yokuqhuba: uthembele kubasebenzi, umbane, i-hydraulic, i-pneumatic, kunye nezinye imikhosi yangaphandle ukuze isebenze i-valve.Njengevalve yeglowubhu, ivalve ye-throttle, ivalve yesango, ivalve yediski, ivalve yebhola, ivalve yeplagi, njalo njalo.

II.Ngokweempawu zesakhiwo

1. Imilo yokuvala: isiqwenga sokuvala sihamba kunye nomgca ophakathi wesihlalo.

2. Ubume besango: isiqwenga sokuvala sihamba kunye ne-centerline perpendicular to seat.

3. Imilo yeplagi: iqhekeza lokuvala yiplunger okanye ibhola ejikelezayo kumgca wayo osembindini.

4. I-Swing-open shape: iqhekeza lokuvala lijikeleza i-axis ngaphandle kwesihlalo.

5. Imilo yeDisc: ilungu lokuvala yidiski ejikelezayo kwi-axis ngaphakathi kwesitulo.

6. Ivalve yesilayidi: inxalenye yokuvala isilayidi kwicala le-perpendicular kumjelo.

III.Ngokusebenzisa

1. Ukuvula/ukucima: isetyenziselwa ukunqumla okanye ukudibanisa umbhobho ophakathi.Njengevalve yokumisa, ivalve yesango, ivalve yebhola, ivalve yeplagi, njalo njalo.

2. Ukulungelelaniswa: isetyenziselwa ukulungisa uxinzelelo okanye ukuhamba kwendawo.Njengevalve yokunciphisa uxinzelelo, kunye nevalve yokulawula.

3. Ukusasazwa: kusetyenziselwa ukutshintsha isalathiso sokuhamba kwendlela ephakathi, umsebenzi wokuhambisa.Njengeqhude leendlela ezintathu, ivalve yokumisa iindlela ezintathu, njalo njalo.

4. Ukukhangela: isetyenziselwa ukuthintela imidiya ukuba ibuyele umva.Njengeevalvu zetshekhi.

5. Ukhuseleko: xa uxinzelelo oluphakathi ludlula ixabiso elichaziweyo, khupha i-excess medium ukuqinisekisa ukhuseleko lwezixhobo.Njengevalve yokhuseleko, kunye nevalve yengozi.

6. Ukuthintela igesi kunye ne-drainage: gcina igesi kwaye ungabandakanyi i-condensate.Njengevalve yomgibe.

IV.Ngokwendlela yokusebenza

1. Ivalve yesandla: ngoncedo lwevili lesandla, isibambo, i-lever, i-sprocket, i-gear, i-worm gear, njl., sebenzisa i-valve ngesandla.

2. Ivalve yombane: Isebenza ngombane.

3. Ivalve yepneumatic: enomoya ocinezelekileyo ukuze isebenze ivalve.

4. Ivalve yeHydraulic: ngoncedo lwamanzi, ioyile, kunye nolunye ulwelo, ukuhambisa amandla angaphandle ukuze kusebenze ivalve.

V. Ngokutshouxinzelelo

1. Ivalve yokufunxa: ivalve enoxinzelelo olupheleleyo ngaphantsi kwe-1 kg/cm 2.

2. I-valve yoxinzelelo oluphantsi: uxinzelelo oluncinci ngaphantsi kwe-16 kg / cm 2 valve.

3. Ivalve yoxinzelelo oluphakathi: uxinzelelo lwegama 25-64 kg / cm 2 valve.

4. Ivalve yoxinzelelo oluphezulu: uxinzelelo lwegama 100-800 kg / cm 2 valve.

5. Uxinzelelo oluphezulu: uxinzelelo lwegama ukuya okanye ngaphezulu kwe-1000 kg / cm i-valve ezi-2.

VI.Ngokutsho kweubushushuye medium

1. Ivalve eqhelekileyo: ilungele ivalve enobushushu obuphakathi bokusebenza kwe--40 ukuya kwi-450℃.

2. Ivalve yobushushu obuphezulu: ilungele ivalve enobushushu obuphakathi obuphakathi kwe-450 ukuya kwi-600℃.

3. Ivalve ekwazi ukumelana nobushushu: ilungele ivalve enobushushu obuphakathi bokusebenza ngaphezu kwe-600℃.

4. Ivalve yobushushu obuphantsi: ilungele ivalve enobushushu obuphakathi bokusebenza obuphakathi -40 ukuya -70℃.

5. Ivalve yeCryogenic: ilungele ivalve enobushushu obuphakathi bokusebenza obuphakathi -70 ukuya -196℃.

6. Ivalve yobushushu obuphantsi kakhulu: ilungele ivalve enobushushu obuphakathi bokusebenza ngaphantsi kwe -196℃.

VII.Ngokutsho kwedayimitha yegama

1. Ivalve yedayamitha encinci: i-diameter encinci ngaphantsi kwe-40 mm.

2. Ivalve yedayamitha ephakathi: i-diameter engu-50 ukuya kuma-300 mm.

3. Iivalve ezinkulu zedayamitha: ububanzi obuyi-350 ukuya kwi-1200 mm.

4. Iivalve zedayamitha eyongezelelweyo-enkulu: iidayamitha ezizigama ezingaphezu kwe-1400 mm.
