Thinta valve (30ch6br)

Ukuze ngesikhathi esifanele amanzi ukugeleza edingekayo kuyendlulela yesimanje ipayipi valve, okuyinto abelwe phakathi cast iron steel valve, ama-valve-rotary futhi uhlole valve. Sakaza amagama yensimbi umphini 30ch6br siqondile kahle wokubacindezela, kagesi ligcina uthi lokuphotha luzungeza, futhi iphayiphi ifakiwe usebenzisa uxhumano flange. valve okunjalo lubaluleke amapayipi oluhamba umusi amanzi, amafutha, noma amafutha, kodwa uthuthwa konemimoya gaseous noma uketshezi kumele kube hlangothi yonke imininingwane nabo ke.

Sakaza yensimbi umphini 30ch6br ingasetshenziswa njengendlela idivayisi ukukhiya eliqinisekile amabhlogo ukugeleza kwamanzi. izindlu wako wenziwe eziqinile cast iron, zethusi isetshenziswa ukwenza uphawu uthi lokuphotha. Le valve yenza zingamelana naphakathi Ukudlula therethrough uma izinga lokushisa kwe-umusi noma amanzi zithutha akuyona ezingaphezu kuka-225 degrees. Kanye asetshenziswa Thepha valve grade 30s41nzh steel esangweni valve - izingxenye uphonswa anikezwa nge lokuphotha retractable.

valve ezinjalo kanye nokufakwa elisetshenziswa amapayipi ukuthi ukuhambisa imikhiqizo ketshezi-non-ezonakalisayo petroleum, uwoyela lamafutha, umusi kanye namanzi, kanye nenye imidiya gaseous futhi uketshezi. Izinzuzo esemqoka valve steel block kuthiwa flanged ngokujoyina umugqa futhi isigaba esiphezulu sokuhlukanisa yobunzima, kanye zithutha lokushisa uketshezi bengase bazikhandlele degrees 450. I ngemoto othini lokuphotha kanye latches brand 30s41nzh ezenziwe ngensimbi, ebusweni zokusebenza izindlu unikezwa engagqwali Welding wire, kanye nokulawula yibhuku.

Valve noma butterfly valve "Butterfly" - a umqondo noma idivayisi ivaliwe-off lokukhuphula ku iphayiphi. I element ukukhiya senziwa disc emise futhi pivotable azungeze i-eksisi elitholakala engela ukugeleza lidluliselwe noma perpendicular ngenhlonipho nalokho. Uvemvane i- umphini esetshenziswa non-nolaka uketshezi, petrochemicals and umusi Ukushisa namanzi, futhi womoya kuphelile, kagesi noma mathupha drive. Othenjwayo umphini uhlobo "Butterfly" lenzelwa nobunzima noma sivale-off, okuyinto ezinwabuzelayo iphayiphi.

Basuke ogibele ipayipi phakathi Flanges kokuzalela lwezimpawu ejwayelekile futhi ezingeziwe alusebenzi, ngoba ulwelwesi valve izindlu uthatha indima lwezimpawu enjalo. Ukuze ukugxilisa ichopho uhlobo "Butterfly" isebangeni phakathi Flanges izindlu ngesikhathi ukushiselwa yayo ekhethekile owazenza izimbobo, futhi ngabo badabula imishudo noma izikopelo. valve nobukhulu bezinhlamvu "Butterfly" uyabulawa kusukela cast iron, isibambo nenduku - ensimbi futhi idrayivu - cast iron, unikezwe engagqwali enamathela. Izinzuzo zihlanganisa ukufakwa ongaphakeme ubude, ubulula ukuthembeka ukusetshenziswa futhi ukufakwa, futhi ukugeleza izinga kungase kushintshwe.

Esilucwecwana isheke valve kuwuhlobo isicisha-mlilo, othomathikhi amadivayisi zokuphepha ukuvimbela okuvela kuyo a komsele backflow. valve maKristu abizwa reverse ngabodwa valve kanye nezinzuzo zabo aqukethe e impilo ende, ongaphakeme ingcindezi iconsi, ukufakwa lula, compactness. umzimba wabo wentiwa grey cast iron, ibhawudo iso kanye emikhonweni - ezenziwe carbon steel, induku entwasahlobo - insimbi engagqwali.

Izinhlanzi 30ch6br enikeziwe uphawu zethusi izindandatho ukuthi vvaltsovyvayutsya e amasondo chassis. naphakathi yokudla isiqondiso kanye nesikhundla op kungenzeka ikhona, kanye yesivalo ivulekile noma ivaliwe ngokuphelele. Ukujikeleza emikhonweni threaded kubangelwa ukuzungeza ligcina uthi lokuphotha luzungeza, ukunyakaza rotary uguqulwe ukunyakaza Translational of the nokwakha uthi lokuphotha esetshenziswa. Ihlinzekwa lokuphotha ngemoto lokuqala eyehlisiwe bese sahamba ngaphandle amasondo nhlonhlo, futhi ivale valve uqobo. Phakathi umzimba okuqinile kanye ikhava igibele paronitovye gasket, futhi phakathi eqinile futhi isivalo itholakala lokuphotha gasket, okuyinto eqondiswa nge ihange imishudo.

Kunalokho ka ukugxusha ibhokisi isetshenziswa asbestos intambo, okuyinto ukuba afuthwe ngesibulali -graphite igrisi. yensimbi Sakaza esangweni valve abhekwa uhlobo esangweni, esezikhundleni eziningana asebenzayo, futhi kumele bahlangabezane imvelo bokusebenzisa bona. Ngakho, medium zithutha ayikwazi ukudlula izinga lokushisa esifanele, futhi ukuhlala iyahambisana nezinto lapho ipayipi ekhiqizwa futhi ingxenye yayo izingxenye. grey cast iron and zethusi isetshenziswa womshini valve, izingxenye abagxeka encibilikisiwe ingulube yensimbi lethusi isetshenziswa ukudala seal ukuba izindlu kanye amadiski.
