Ama-valve, Genebre adjustable

Ukuphepha valve adjustable ibalulekile ephephile nokuqhutshwa kohlelo lapho amanzi, umusi noma ezinye izinto kungase kuhlinzekwe ngaphansi eqinile ingcindezi. Iphayiphi, okuyinto sidlule, abakwazi ukugcina ingcindezi. Ngenxa yalokho ukuthi kugqamuke amalangabi kungenzekani yonke imiphumela. Yiziphi adjustable ukuphepha valve, amisa kanjani emsebenzini?

A valve ukuphepha

Ukuphepha valve adjustable livaleke-off valve kukhona oyibamba oqondile. Basebenza ngqo imvelo, esinikela izinqubo zokukhiqiza. Iningi ngokuvamile, ke okungukuthi amanzi. Kunalokho kungase emoyeni, umusi, igesi yemvelo, ethylene, noma nezinye izinto ungathathi ngamawala nge izinto zokwakha ukwenza valve.

Ukuphepha valve yokwenza ingcindezi, wenza imisebenzi emibili. Okokuqala uveza indawo ukusebenza uma ingcindezi ohlelweni. Kodwa wabe uhlanganisa indlela kukho. Lokhu kwenzeka ngokushesha ngemva kokuba Umfutho ongaphakathi isistimu uhlaliseke.

isicelo

valve ukuphepha ashintshekayo efakwe:

• izinhlelo zezimboni;
• yasendlini.

Bona ukuvimbela ithonya izici zangaphakathi nezangaphandle. Isigaba sokuqala sihlanganisa ezihlukahlukene ukuhluleka kwehadi noma umthelela imithombo sangaphandle lokushisa eliphezulu. Lokhu kungaba nephutha phakathi kokufakwa kohlelo noma idivayisi.

Yangaphakathi izici - ngokomzimba izinqubo ngaphakathi ocingweni noma uhlelo, okuyinto phambili nokwanda ingcindezi.

Umgomo we operation

ukusebenza umphini kusekelwe yokuthi ngaphakathi kuwo bekulokhu kukhona izakhi ezimbili isikhashana zilingana. Ingxenye, ngokuthi ukuqunjelwa, kugcina ingxube ukusebenza kusukela ophumayo kohlelo. Ubethula akuvumelekile ukuhambisa Ukudayela (entwasahlobo), okuyinto has a amandla athile compressive. Kodwa lapho ingcindezi ngaphakathi ohlelweni sihamba umugqa opharetha ezithile, entwasahlobo ingasakwazi ukubamba ukhiye. Kuyinto onomfutho, ukuqunjelwa (emikhonweni) liyaphuma futhi ukucindezela kontanga naphakathi uphumela phandle - nomaphi umphini nomklamo walo oqondile.

Ngemva ingcindezi kuzole, entwasahlobo ubuyela isikhundla saso ekuqaleni, ukusunduza Ilokhi endaweni.

Izimfuneko valve

Kumelwe:

1. Isikhathi kanye unlatch compulsorily ngaphansi lezi nemingcele ingcindezi.
2. Yiba umthamo evumela ukwehlisa ingcindezi ngokweqile ngokushesha.
3. Qiniseka ukubuyela isiqhebezo endaweni, ukuqinisekisa yobunzima kohlelo.

ngezigaba

It wenziwa ngokuvumelana nemingcele ezahlukene.

I yokusebenza isimiso ukuphepha valve Are ngokuqondile noma ngokungaqondile (ukuze umsebenzi, kufanele ugesi).

Zingase ahlukaniswe nezinto lapho (zethusi, insimbi, insimbi).

Ngu ubunjalo ukuqunjelwa ephakamisa valve zihlukaniswe ezilinganiselwe esenzweni nedivayisi rocker.

Ngaphezu kwalokho, ama-valve kungenzeka amancane, aphakathi nendawo kanye-lift Okugcwele. Futhi lokhu akuyona yonke ngezigaba kungenzeka.

Ukuphepha umphini ezilungisiwe Geneble 3190 (Spain)

Ngokusho uhlobo uxhumano libhekisela coupling. Lesi sangoma ukusebenza kungaba amanzi, umusi, amagesi inert futhi uketshezi.

umzimba wako wenziwe high ngethusi. Valve ukuphepha 1 '' ine zethusi umzimba adjustable. Spool futhi ingilazi ngethusi. Spring is ezenziwe ngensimbi lashukumisa. Teflon gasket.

Operating ingcindezi valve 16 kg / m ² (ibha).

Ingcindezi adjustable kusuka 1 kuya 12 kg / m ^2. Ngesikhathi imboni, lesi silinganiso isethelwe 3 kgf / m ^2.

Okulungisekayo impendulo ingcindezi ngokulungisa isikulufa. Uma uvula ke ngokwewashi, ukubaluleka ukwanda, futhi uma ingqondo esihambelana encishisiwe.

Ivunyelwe ingcindezi ngokweqile afika ku-10% we ezivamile.

izinga lokushisa lokusebenza kusuka -10 ° C kuya ku-180 ° C, esiphezulu 200 ° C kubhekwa.

ukukhweza

Ukuze ufake kahle valve, kubalulekile ukubheka imvelo isiqondiso inkomba, esisogwini umzimba.

Ufaka valve kufanele kube mpo, kungenjalo ngeke zisebenze.

Ukuze imvelo ukusebenza akuyona bopha, usebenzisa izinto okuyinto ningangeni ukuphendula nalo.

Ukukhweza valve ogibele ipayipi futhi uqale ukucindezela ukhiye uphawu ngaphakathi ngentambo. Nut ayikwazi ska. Leli payipi osenyameni iqondiswa phansi uketshezi ababuyelanga nyovane, fixed kangangokuba akucindezelwe emzimbeni.

Valve ezilungisiwe Valtec

Ukuphepha umphini ukulungiswa Valtec 1831 ezimazombezombe ukukhishwa amanzi noma ezinye zokusebenza uketshezi (igesi) emva ingcindezi therein intando kuyanda ngaphezu kuvunyelwe.

idivayisi valve

I spool nge gasket elise ngaphakathi izindlu. Yena isekelwa nge isiphethu losendzaweni engilazini, esivikela ke nokusondelana ngaphandle.

Degree kokucindezelwa kulawulwa esebenzisa wagxila washers. Bush ophoqelelwe ukuvulwa, okuyinto uhlezi phezu induku nati ezimbili, iza mbeni emkhonweni control. Ngakho, entwasahlobo onomfutho, kodwa hhayi ezibucayi.

Lapho ukucindezela kwandisa ngenhla evamile, entwasahlobo onomfutho spool namandla liyavuleka. Amanzi noma enye into egcina ipayipi. Ingcindezi lehliselwa, njengoba kudingwa yi-valve.

Ngemva ingcindezi kwehle futhi wabuya evamile, entwasahlobo yandisa. Ngemva emkhonweni it is hhayi ngokucindezela kanzima kangaka. Uhlelo selinqunyiwe.

izici

Isihlalo ubukhulu kungenzeka kusukela 1/2 '' 2 '' nokwanda kuka- 1/4 '', 2, 2½ '' futhi 3 ''.

Ingcindezi ukuvulwa umnyuziki ulingana izikhathi 1.1 isethi ingcindezi, ukuvalwa - 0.9 yokucindezela kulungiselelwa.

Ukusebenza lokushisa hhayi ephakeme kuka-180 ° C.

Valve usebenza emazingeni okushisa ezisukela -25 ° C kuya ku-60 ° C (amanzi).

Kulokhu, it ibalwa 5000 nowe, futhi iminyaka ngokuvamile hhayi ngaphansi kuka 15.

Isiqinisekiso futhi umshwalense ehlotshisiwe kuwo wonke ama-valve Valtec iminyaka engu-7.

valve Safety angavulwa ngesandla adjustable. Lokhu kwenziwa ukuze kuqinisekiswe ukuseviswa yabo. Kungcono ukuzihlola njalo ngemva kwezinyanga eziyisithupha.

valve Ukuphepha futhi adjustable Geneble Valtec 12.2.085-2002 ahlangane GOST futhi GOST 24570-81.
