3, ivalvu yebhola: iphuhliswe kwivalvu yeplagi, iindawo zayo zokuvula nezokuvala ziyibhola, kusetyenziswa ibhola ejikeleze ukujikeleza kwe-stem axis 90° ukuze kufezekiswe injongo yokuvula nokuvala. Ivalvu yebhola isetyenziselwa kakhulu ukusika, ukusasaza nokutshintsha indlela yokuhamba okuphakathi kwipayipi. Ivalvu yebhola enokuvulwa okufana ne-v ikwanomsebenzi olungileyo wokulawula ukuhamba.
Iingenelo:
(1) Ngokumelana nokuhamba kwamanzi okuphantsi (ngokwenene yi-0);
② Ngenxa yokuba ayizukubambeka emsebenzini (xa kungekho lubricant), ingafakwa ngokuthembekileyo kwi-media ebolayo kunye nolwelo olusezantsi lokubila;
Kuluhlu olubanzi loxinzelelo kunye nobushushu, ingafikelela ekutywinweni okupheleleyo;
④ Ingenza ukuvulwa nokuvalwa ngokukhawuleza, kwaye ixesha lokuvulwa nokuvalwa kwezinye izakhiwo yi-0.05-0.1s kuphela ukuqinisekisa ukuba ingasetyenziswa kwinkqubo yokuzenzekela yebhedi yovavanyo. Ukuvulwa nokuvalwa ngokukhawuleza kwevalvu, ukusebenza ngaphandle kokuchaphazeleka;
(5) Iindawo zokuvala ezingqukuva zinokubekwa ngokuzenzekelayo kwindawo yomda;
⑥ Isixhobo sokusebenza kumacala omabini esitywino sithembekile;
⑦ Xa ivuliwe ngokupheleleyo kwaye ivaliwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo uyahlukaniswa kwi-medium, ngoko ke i-medium edlula kwi-valve ngesantya esiphezulu ayizukubangela ukukhukuliseka komphezulu wokutywina;
⑧ isakhiwo esincinci, esinobunzima obuphantsi, singathathwa njengesakhiwo sevalvu esifanelekileyo kwinkqubo ephakathi yobushushu obuphantsi;
⑨ Umzimba wevalvu olinganayo, ingakumbi ulwakhiwo lomzimba wevalvu odibeneyo, unokuthwala uxinzelelo oluvela emthonjeni wepayipi;
⑩ Iindawo zokuvala zinokumelana nomahluko ophezulu woxinzelelo xa zivala. (11) Umzimba wokuwelda wevalvu yebhola, unokungcwatywa ngqo emhlabeni, ukuze iindawo zangaphakathi zevalvu zingakhukuli, ubomi benkonzo obuphezulu obufikelela kwiminyaka engama-30, yeyona valve ifanelekileyo kwimibhobho yeoyile negesi yendalo.
Iingxaki:
(1) Ngenxa yokuba izinto zeringi yokutywina isihlalo sevalvu ephambili ziyi-ptfe, ayisebenzi phantse kuzo zonke iikhemikhali, kwaye ineempawu ezipheleleyo ze-coefficient encinci yokungqubana, ukusebenza okuzinzileyo, ukuguga okulula, uluhlu olubanzi lobushushu kunye nokusebenza kakuhle kokutywina. Kodwa iimpawu zomzimba ze-PTFE, kubandakanya i-coefficient ephezulu yokwandiswa, uvakalelo lokuhamba okubandayo kunye nokuqhuba kakubi kobushushu, zifuna ukuba isitywina sesihlalo siyilwe malunga nezi mpawu. Ngenxa yoko, xa izinto zokutywina ziqina, ukuthembeka kwesitywina kuyonakala. Ngaphezu koko, ukumelana nobushushu be-PTFE kuphantsi kwaye kunokusetyenziswa kuphela phantsi kwemeko engaphantsi kwe-180℃. Ngaphezulu kobu bushushu, izinto zokutywina ziya kuguga. Kwimeko yokusetyenziswa ixesha elide, ngokubanzi ayisetyenziswa kwi-120℃ kuphela.
② Ukusebenza kwayo okulawulekayo kubi kunevalvu yeglobe, ingakumbi ivalvu yomoya (okanye ivalvu yombane).
