Valve yo guhagarika ikoreshwa cyane cyane mu kugenzura no guhagarika amazi atembera mu muyoboro. Itandukanye na valve nka valves z'umupira na valves z'irembo kuko zagenewe kugenzura amazi atembera kandi ntizigarukira gusa kuri serivisi zo gufunga. Impamvu valve yo guhagarika yitwa gutyo ni uko igishushanyo mbonera cya kera kigaragaza umubiri runaka w'uruziga kandi gishobora kugabanywamo ibice bibiri, bitandukanyijwe na equator, aho amazi atembera ahindura icyerekezo. Ibintu by'imbere by'intebe yo gufunga akenshi si uruziga (urugero, valves z'umupira) ariko akenshi ziba zifite ishusho y'umubumbe, hemispherical, cyangwa plug. Valve z'umubumbe zigabanya amazi atembera cyane iyo zifunguye kuruta valves z'irembo cyangwa umupira, bigatuma umuvuduko mwinshi unyuramo. Valve z'umubumbe zifite imiterere itatu y'ingenzi y'umubiri, imwe muri yo ikoreshwa mu kugabanya umuvuduko unyura muri valve. Kugira ngo umenye byinshi ku zindi valves, nyamuneka reba Inyoborabitekerezo yacu y'abaguzi ba valve.

Igishushanyo mbonera cy'imvange

Valve yo guhagarara igizwe n'ibice bitatu by'ingenzi:umubiri wa valve n'intebe, disiki ya valve n'igitereko, gupakira no gupakira. Mu gihe ukora, zunguza umugozi unyuze mu gikoresho cy'amaboko cyangwa cy'imashini ikoresha amashanyarazi kugira ngo uzamure disiki ya valvu uhereye ku ntebe ya valvu. Inzira y'amazi inyura muri valvu ifite inzira isa na Z kugira ngo amazi ashobore kugera ku mutwe wa disiki ya valvu. Ibi bitandukanye na valvu z'irembo aho amazi aba agororotse ku irembo. Iyi miterere rimwe na rimwe isobanurwa nk'umubiri wa valvu ifite ishusho ya Z cyangwa valvu ifite ishusho ya T. Inzira n'aho isohoka bifatanye.

Izindi imiterere irimo inguni n'imiterere isa na Y. Muri valve ihagarika inguni, aho isohoka ni 90 ° uvuye aho yinjira, kandi amazi atembera mu nzira isa na L. Mu miterere y'umubiri wa valve isa na Y cyangwa Y, igiti cya valve cyinjira mu mubiri wa valve kuri 45 °, mu gihe aho yinjira n'aho asohoka biguma ku murongo, kimwe no mu buryo bw'inzira eshatu. Ubudahangarwa bw'imiterere y'inguni mu gutembera ni buto ugereranyije n'ubw'imiterere isa na T, kandi budahangarwa bw'imiterere isa na Y ni buto. Valve z'inzira eshatu ni zo zikunze kugaragara muri ubwo bwoko butatu.

Disiki yo gufunga ikunze kuba ifatanye n'intebe ya valve, ariko hari n'indi disiki irambuye ishobora gukoreshwa. Iyo valve ifunguye gato, amazi atembera neza hafi ya disc, ndetse n'uburyo intebe ya valve na disiki bikwirakwira. Bityo, valve ikora neza iyo amazi agabanutse. Muri rusange, icyerekezo cy'amazi kiba yerekeza ku ruhande rw'agace k ...

Disiki cyangwa plagi yo gufungaakenshi igezwa ku ntebe ya valve inyuze mu kazu kugira ngo imenye neza ko ikora neza, cyane cyane mu bikorwa birimo umuvuduko mwinshi. Imiterere imwe n'imwe ikoresha intebe ya valve, kandi agafunga ku ruhande rw'inkoni ya valve kuri disiki gafatana n'intebe ya valve kugira ngo gakureho umuvuduko ku gipfunyika iyo valve ifunguye neza.

Dukurikije imiterere y'ikintu cyo gufunga, valve yo guhagarika ishobora gufungurwa vuba hakoreshejwe uburyo bwinshi bwo gufunga kugira ngo itangire vuba inzira (cyangwa igafungwa kugira ngo itangire gutemba), cyangwa igafungurwa buhoro buhoro hakoreshejwe uburyo bwinshi bwo gufunga kugira ngo itangire neza inzira inyura muri valve. Nubwo hari igihe plugs zikoreshwa nk'ibintu byo gufunga, ntizigomba kwitiranywa na plugs, ari zo mashini zizunguruka kimwe cya kane, nk'imashini zizunguruka, zikoresha plugs aho gukoresha umupira kugira ngo zihagarike kandi zitangire gutemba.

ubusabe

Utwuma duhagarika amazi dukoreshwa mu kuzimya no kugenzura inganda zitunganya amazi yanduye, inganda zitanga amashanyarazi n'inganda zitunganya amazi. Dukoreshwa mu miyoboro y'umwuka, mu miyoboro ikonjesha, mu buryo bwo gusiga amavuta, n'ibindi, aho kugenzura ingano y'amazi anyura muri utwuma bigira uruhare runini.

Uburyo bwo guhitamo ibikoresho by'umubiri w'imvange y'isi busanzwe ni icyuma gikozwe mu cyuma cyangwa umuringa / umuringa mu buryo buri hasi, hamwe n'icyuma cya karuboni cyangwa icyuma kitagira umuvuduko mwinshi mu buryo buri hejuru n'ubushyuhe bwinshi. Ibikoresho byagenwe by'umubiri w'imvange ubusanzwe biba birimo ibice byose by'umuvuduko, kandi "trim" yerekeza ku bindi bice bitari umubiri w'imvange, harimo n'intebe y'imvange, disiki n'igiti. Ingano nini igenwa n'ubwoko bw'umuvuduko wa ASME, kandi bolts zisanzwe cyangwa flanges zo gusudira zirategetswe. Gupima ingano y'imvange y'isi bisaba imbaraga nyinshi kuruta gupima ubundi bwoko bw'imvange kuko kugabanuka k'umuvuduko kuri imvange bishobora guteza ikibazo.

Imiterere y'imirongo izamuka ni yo ikunze kugaragara cyane muri valve zihagarara, ariko valve zizamuka nazo ziraboneka. Agasanduku gakunze gushyirwaho umugozi kandi gashobora gukurwaho byoroshye mu gihe cy'igenzura ry'imbere rya valve. Intebe ya valve na disiki biroroshye gusimbuza.

Vali zo guhagarikaUbusanzwe bikoresha ikoranabuhanga hakoreshejwe piston y'umwuka cyangwa diaphragm actuators, zikora neza ku gice cy'inyuma cy'imashini kugira ngo zimure disiki mu mwanya wayo. Piston / diaphragm ishobora gupfundikirwa cyangwa igafungwa iyo imashini itakaje umuvuduko w'umwuka. Hakoreshwa kandi icyuma gikoresha amashanyarazi gisimburana.
