Kuyaziwa ukuthi ukulimala kokugqwala kwensimbi kunomthelela omkhulu empilweni ye-valve, ukwethembeka kanye nempilo yesevisi.Isenzo sezinto eziwumshini nokubola kwensimbi kukhulisa kakhulu ukuguga okuphelele kwendawo yokuxhumana.Inani eliphelele lokuguga endaweni ekhungathekile ye-valve ngesikhathi sokusebenza.Ngesikhathi sokusebenza kwe-valve, izindawo ezingqubuzanayo ziyagugiswa futhi zonakaliswe ngenxa yokusebenzisana ngesikhathi esisodwa komshini namakhemikhali noma we-electrochemical phakathi kwensimbi nendawo ezungezile.Kuma-valve, izimo zezulu zokusebenza kwawo kwepayipi ziyinkimbinkimbi, futhi ukuba khona kwe-hydrogen sulfide, i-carbon dioxide kanye namanye ama-acids e-organic emithonjeni yezindaba njengamafutha, igesi yemvelo kanye namanzi e-reservoir kwandisa amandla abhubhisayo endaweni yensimbi futhi ngokushesha alahlekelwe amandla. ikhono lokusebenza.

Ukugqwala kwamakhemikhali ezinsimbi kuncike ezingeni lokushisa, umthwalo wemishini wezingxenye zokungqubuzana, ama-sulfide aqukethwe ezintweni zokugcoba, ukuzinza kokumelana ne-asidi, isikhathi sokuxhumana se-medium, i-catalysis yezinsimbi kwinqubo ye-nitriding, ijubane lokuguqulwa kwe-molecule-kuya-metal yezinto ezibolayo, njalonjalo.Ngakho-ke, izindlela zokunqanda ukugqwala kwe-valve yensimbi (noma izilinganiso) kanye nokusetshenziswa kwamavalvu ezinto zokwenziwa, kuzoba ngesinye sezihloko zamanje zocwaningo lwemboni yamavalvu.

1. I-Anti-corrosion ye-Metal Valve

Ama-valve ensimbi avikelekile ekugqwaleni ngokuwamboza ngopende ovikelayo (upende, umbala, izinto zokugcoba, njll.) ovikela i-valve ekugqwaleni ngesikhathi sokukhiqiza, ukugcinwa, ukuthutha, nokusetshenziswa.

Indlela ye-anticorrosion ye-Metal Valve incike esikhathini sokuvikela esidingekayo, izimo zokuhamba nezokugcina, izici zokwakha ama-valve nezinto zokwakha, yebo, ukucabangela umphumela wezomnotho wokuphakamisa i-anticorrosion.

Kunezindlela ezine eziyinhloko zokuvikela ukugqwala kwe-Metal Valves kanye nezingxenye zazo:

1.1 Khipha inhibitor eguquguqukayo ye-corrosion inhibitor emkhathini womhwamuko (oboshwe ngephepha lokusula, eliphephethwa egumbini lomkhiqizo, njll.).

1.2 Sebenzisa amanzi avinjiwe notshwala.

1.3 Gcoba ucwecwe oluncane lwento evimbela ukubola ebusweni bevalvu nezingxenye zayo.

1.4 Gcoba ifilimu evinjiwe noma ifilimu ye-polymer ebusweni bevalvu nezingxenye zayo.

2. Ukusetshenziswa Kwe-Valve Yempahla

Ama-valve okwenziwa aphakeme kunama-valve ensimbi ezimweni eziningi ezigqwalile, okokuqala ekumelaneni nokugqwala, okwesibili ngesisindo senetha, futhi amandla awo ancike ekubunjweni, ekuhlelekeni, kanye nenani lemicu eqinisayo.(ngokujwayelekile, uma likhulu iphesenti lefibre, amandla enhlanganisela ayanda.)

Kuzinhlelo zokusebenza zeValve, isisindo esiyisisekelo sokuqukethwe kwe-fiber ku-30% -40%, futhi ukuzinza kwayo kwamakhemikhali kunqunywa ikakhulukazi izici ze-resin noumenon ze-fiber encapsulated emkhiqizweni wokugcina.Kumavalvu okwenziwa, umzimba we-polymer oqinile ungase ube i-Thermoplastic (njenge-PVC-polyvinylidene fluoride, i-PPS-poly(p-phenylene sulfide), njll.) noma i-thermosetting resin (njenge-polyester, i-ethylene ne-epoxy, njll.) .

I-thermosetting resin igcina amandla ayo emazingeni okushisa aphezulu kune-Thermoplastic resin (okungukuthi intlaka ye-thermosetting inezinga lokushisa eliphezulu lokuguquguquka kokushisa).
