Ku rugero runaka, valve y'isi n'iy'irembo bishobora kuvugwa ko bifite aho bihurira henshi. Ese byavugwa ko valve y'isi n'iy'irembo bishobora kuvangwa koko? Shanghai Dongbao Valve Manufacturing Co., Ltd. irahari kugira ngo igusubize iki kibazo.

1. Imiterere
Iyo umwanya wo gushyiramo ari muto, nyamuneka witondere amahitamo:
Itsindavalve y'iremboishobora gufungwa neza hamwe n'ubuso bwo gufunga bitewe n'igitutu kiri hagati, kugira ngo hatazagira ingaruka zo gusohoka. Mu gufungura no gufunga, igice cy'imbere cya valve n'ubuso bwo gufunga icyicaro cya valve bihora bihurirana kandi bigaterana, bityo ubuso bwo gufunga bworoshye kwambara. Iyo valve y'irembo iri hafi gufunga, itandukaniro ry'igitutu hagati y'imbere n'inyuma by'umuyoboro ni rinini, bigatuma ubuso bwo gufunga burushaho kwangirika.
Imiterere ya value y'irembo izaba igoye kurusha value yo kuzimya. Ukurikije uko bigaragara, value y'irembo ni ndende kurusha value yo kuzimya kandi value yo kuzimya ni ndende kurusha value y'irembo mu gihe cy'aho imeze kimwe. Byongeye kandi, value y'irembo ishobora kugabanywamo inkoni yera n'icyuma cyijimye. Value yo kuzimya ntabwo ikora.
2. Ihame ry'imikorere
Iyo valve yo kuzimya ifunguwe kandi igafungwa, uruti rurazamuka, ni ukuvuga ko iyo uruziga rw'intoki ruzungurutse, uruziga rw'intoki ruzazunguruka rukazamuka hamwe n'uruti. Valve yo ku irembo izunguruka uruti rw'intoki kugira ngo uruti rw'uruti rugende ruzamuka runamanuka, kandi aho uruziga rw'intoki ruherereye ntihagire icyo ruhinduka.
Igipimo cy'amazi gitandukanye, valve y'irembo irasabwa kuba ifunguye cyangwa ifunze neza, ariko valve yo guhagarika ntabwo ikenewe. Valve yo gufunga ifite icyerekezo cy'aho yinjira n'aho asohokera, kandi valve y'irembo nta byangombwa by'icyerekezo cy'aho yinjira n'aho asohokera bifite.
Byongeye kandi, valve y'irembo ifite imiterere ibiri gusa: ifunguye neza cyangwa ifunze neza, urwego rwo gufungura no gufunga irembo ni runini, kandi igihe cyo gufungura no gufunga ni kirekire. Uburyo bwo kugenda bw'icyuma gifunga icyuma cya valve ni gito cyane, kandi icyuma gifunga icyuma cya valve gishobora guhagarikwa ahantu runaka mu gihe cyo kugenda kugira ngo gihindurwe neza. Valve y'irembo ishobora gukoreshwa gusa mu gukata, kandi nta yindi mirimo ifite.
3. Itandukaniro mu mikorere
Valve yo kuzimya ishobora gukoreshwa mu gukata no gukosora amazi. Ubudahangarwa bw'amazi ya valve y'isi ni bunini ugereranije, kandi biragoye kuyifungura no kuyifunga, ariko kubera ko intera iri hagati y'isahani y'valve n'ubuso bwo kuyifunga ari ngufi, inzira yo kuyifungura no kuyifunga ni ngufi.
Kubera kovalve y'iremboishobora gufungurwa neza gusa no gufungwa neza, iyo ifunguwe neza, ubushobozi bwo kwirinda amazi mu gice cy'umubiri w'imashini yo mu bwoko bwa valve buba hafi ya zeru, bityo gufungura no gufunga imashini yo mu bwoko bwa valve bizagabanya cyane imbaraga, ariko irembo riri kure y'ubuso bwo gufunga kandi igihe cyo gufungura no gufunga ni kirekire.
4. Gushyiraho no gukoresha neza
Ingaruka za valvu y'irembo mu byerekezo byombi ni zimwe. Nta gisabwa ku mabwiriza yo kwinjira n'ayo gusohokera kugira ngo ishyirweho, kandi icyo gikoresho gishobora kuzenguruka mu byerekezo byombi. Valvu yo gufunga igomba gushyirwaho hakurikijwe icyerekezo cy'umwambi ku mubiri wa valvu. Hariho kandi amabwiriza asobanutse neza yerekeye icyerekezo cy'aho valvu yo gufunga n'aho isohoka. Valvu yo mu gihugu cyanjye "Sanhua" ivuga ko icyerekezo cy'inzira ya valvu yo gufunga kigomba kuva hejuru kugeza hasi.
Valve yo kuzimya iri hasi imbere no hanze. Urebye inyuma, biragaragara ko umuyoboro utari ku murongo utambitse w'icyiciro kimwe. Inzira y'inzira ya valve y'irembo iri ku murongo utambitse. Inzira ya valve y'irembo ni nini kuruta iya valve yo guhagarika.
Urebye uburyo amazi atemba, uburyo amazi atemba bwa valve y'irembo buba buto iyo bufunguwe neza, kandi uburyo amazi atemba bwa valve ihagarika imizigo buba bunini. Igipimo cyo kwirinda amazi atemba cya valve isanzwe y'irembo ni hafi 0.08 ~ 0.12, imbaraga zo gufungura no gufunga ni nto, kandi icyuma gishobora gutemba mu byerekezo bibiri.
Ubudahangarwa bw'amazi asanzwe yo kuzimya ni inshuro 3-5 z'amazi yo kuzimya. Mu gufungura no gufunga, bisaba ko ifungwa kugira ngo ipfundikwe. Igice cy'imbere cya valve yo kuzimya ntigikora ku gice cyo kuzimya iyo gifunze burundu, bityo ubusaza bw'amazi yo kuzimya ni buto cyane. Valve yo kuzimya igomba kongeramo actuator bitewe n'imbaraga nyamukuru z'amazi igomba kwitondera uburyo bwo kugenzura torque.
Iyo valve yo kuzimya ishyizwemo, icyuma gishobora kwinjira kiri munsi y'umutima wa valve no kwinjira kiri hejuru mu buryo bubiri.
Akamaro k'uburyo bw'amashanyarazi bwinjira munsi y'umutima wa valve ni uko uburyo bwo gupakira butari munsi y'umuvuduko iyo valve ifunze, ibyo bikaba bishobora kongera igihe cyo gupakira, kandi bigasimbuza uburyo bwo gupakira iyo umuyoboro uri imbere ya valve uri munsi y'umuvuduko.
Ingorane y'uburyo bwo kwinjira buturutse hasi ku gice cy'imbere cya valve ni uko imbaraga zitwara za valve ari nini cyane, inshuro zigera kuri 1.05 ~ 1.08 z'ubwinjiriro bwavuzwe haruguru, igice cy'impande gikoreshwa imbaraga nyinshi, kandi igice cy'impande cyoroshye kugipfunyika.
Kubera iyo mpamvu, uburyo icyuma cyinjiramo kivuye hasi muri rusange bukwiriye gusa ibyuma bihagarara bifite umurambararo muto (munsi ya DN50). Ku mashini zihagarara zirenze DN200, icyuma cyinjiramo kivuye hejuru. Imashini ifunga amashanyarazi muri rusange ikoresha uburyo icyuma cyinjiramo kivuye hejuru.
Ingorane y'uburyo icyuma cyinjira kivuye hejuru ni ikinyuranyo cy'uburyo icyuma cyinjira kivuye hasi. Mu by'ukuri, gishobora gutembera mu byerekezo byombi, gusa ukurikije ibitekerezo bitandukanye.
5. Ikimenyetso
Ubuso bw'isi bupfundikiyevalveni uruhande ruto rwa trapezoidal rw'umutima wa valve (reba imiterere y'umutima wa valve kugirango umenye ibisobanuro birambuye). Iyo umutima wa valve uguye, bingana no gufunga valve (niba itandukaniro ry'umuvuduko ari munini, birumvikana ko gufunga bidakomeye, ariko ingaruka zo kurwanya gusubira inyuma ntabwo ari mbi). Valve y'irembo ifunze ku ruhande rw'icyuma cy'irembo cy'umutima wa valve, ingaruka zo gufunga ntabwo ari nziza nk'iya valve yo guhagarara, kandi umutima wa valve ntuzafungwa nk'uko valve yo guhagarara ifunze iyo umutima wa valve uguye.
