Ukwethulwa kwezinto zokwakha uphawu lwe-valve-tw valve

Izinto ze-valve zokubopha ziyingxenye ebalulekile yokubekwa uphawu kwe-valve. Yiziphi izinto zokwenza uphawu lwe-valve? Siyazi ukuthi izinto zokukhala kokubopha uphawu kwe-valve zihlukaniswe izigaba ezimbili: insimbi nengezona insimbi. Okulandelayo ukwethulwa okufushane kwezimo zokusetshenziswa kwezinto ezahlukahlukene zokubopha, kanye nezinhlobo ze-valve ezivame ukusetshenziswa.

1. Injoloba zokwenziwa

Izakhiwo eziphelele zenjoloba zokwenziwa njengokumelana kawoyela, ukumelana nokushisa nokuphikiswa kokugqwala kungcono kunaleyo yerabha yemvelo. Ngokuvamile, izinga lokushisa elisetshenzisiwe lerabha yokwenziwa yi-T≤150 ℃, futhi izinga lokushisa lerabha lemvelo yi-T≤60 ℃ .Rubber lisetshenziselwa ukuvala ama-valves omhlaba,I-Rubber ehleliwe gate valu, ama-valves e-diaphragm,rUBber wahlelwa i-butterfly valve, rUbber uhlezi i-Swing Check valve (Bheka ama-valves), Phina ama-valve namanye ama-valves anengcindezelo ye-ominal Pressure Pn≤1MPPa.

2. I-Nylon

I-Nylon inezimpawu zokuphikiswa okuncane kwezingxabano kanye nokuphikiswa okuhle kokugqwala. I-Nylon isetshenziselwa kakhulu ama-valves ebhola kanye nama-valves e-globe anokushisa Tą90 ℃ kanye nengcindezi yokuqothuka PN≤32MPA.

3. I-PTFE

I-PTFE isetshenziswa kakhulu ama-valves e-Global Vales,ama-gang valves, ama-valves e-ball, njll. Ngokushisa T≤232 ℃ kanye nengcindezi yokuqothuka PN≤6.4MPA.

4.

I-cast iron isetshenziselwaI-SAGE VALVVVE, i-valve ye-tlob valve, i-valve ye-plug, njll.

5. I-Babbitt Alloy

I-Bablitt Alloy isetshenziselwa i-ammonia hlaba i-valve nge-Temperature T-70 ℃ kanye nengcindezi yokuqothuka ye-Pn≤2.5MPA.

6. I-Copper Alloy

Izinto ezijwayelekile ze-Aloys zethusi zingama-6-6-3 tin bronze kanye ne-58- 2 Manganese yethusi. I-Copper Alloy inokumelana kahle nokuvimbela amanzi futhi ilungele amanzi kanye nomusi nge-Temperature T≤200 ℃ kanye nengcindezi yokuqothuka. Kuvame ukusetshenziswaama-gang valves, ama-valves we-tlobo gebe,Bheka ama-valves, ama-valves axhume, njll.

7. Insimbi ye-Chrome engenasici

Amamaki asetshenziswa kakhulu wensimbi ye-chromium engagqwali ayi-2CR13 ne-3CR13, ecinyiwe futhi eshubile, futhi ibe nokuphikiswa okuhle kokugqwala. Imvamisa isetshenziswa kuma-valve ama-valves afana namanzi, umusi kanye nophethiloli ngokushisa T≤450 ℃ kanye nengcindezi yokuqothuka PN≤32MPA.

8. I-Chromium-Nickel-Titanium-Titanium Engagqwali

Ibanga elisetshenziswa kaningi le-chromium-nickel-titanium-titanium esingenacala yi-1CR18NI9TI, enokumelana kahle nokuphikiswa, ukumelana nokuguguleka kanye nokuphikiswa kokushisa. Ilungele umusi, i-nitric acid kanye neminye imidiya nge-learte t≤600 ℃ kanye nengcindezelo ye-pun≤6.4MPA, esetshenziselwe i-valve yeGlobe, i-valve yebhola, njll.

9. Insimbi ye-nitrided

Ibanga elisetshenziswa kakhulu lensimbi ye-nitrided ngu-38crmoala, elinokumelana kahle nokugqwala nokulwa kabusha ngemuva kokucwaswa kwezimali. Isetshenziswa kakhulu e-Power Station Gate Valve nge-Temperature T7540 ℃ kanye nengcindezelo yokuqothuka PN≤10MPA.

10. UCoroning

Ukubopha ngokuqondile kucubungula indawo yokubopha uphawu kusuka ezintweni zomzimba we-valve noma umzimba we-disc, bese kufezekisa ukwelashwa okukhohlisayo komhlaba, indawo ebekelwe uphawu inokumelana kahle. Isetshenziswa esiteshini samandla i-blowdown valve.
