Valve Shut-off for amanzi naphakathi ketshezi

Shut-off valve kuyinto valve ogama njongo fast ezithothene ipayipi iphelele noma ingxenye ku izidingo zobuchwepheshe noma uma eziphuthumayo. Inzuzo Its main isivinini, njengoba eduze zedivayisi entwasahlobo ngesikhathi kwabangela ngokushesha. Cocking entwasahlobo eyalo i actuator kagesi noma womoya.

Shut-off valve: zinhlobo

Lolu hlobo lwe-valve kungaba piston noma diaphragm actuator. Ngaphezu kwalokho, valve livaleke-off kungaba basonta uhlobo olulodwa: yokuxhumana, emincane, isihlalo esisodwa noma kabili. Ngendlela ukuvala lolu hlobo ukuqinisa kuyinto: entwasahlobo, pneumatically, noma electromagnetically umthwalo lockable.

Ububanzi

Shut-off INGAPHANDLE umzimba propulsive esetshenziswa ukuthutha uginindela-olwalwenza noma okunobuthi ezindaweni. Kulesi kudivayisi kungekho esishintshashintshayo amile. Steel nge shutoff umphini emincane piston wokubacindezela nemphumela bemave lamabili, isetshenziswa ngesikhathi ophezulu imvelo.

Okwamanje, le uhlobo ukuqinisa has izici ezifana constructional ngalolo medium ukulawula therein kakhulu ngenkuthalo isicelo umusi. valve okunjalo icushiwe ngoba 1.5-10 imizuzwana. isilinda zayo kanye nezindlu a gasket, isilonda Kuvunguza, ezenziwe ngensimbi, a ukugqwala nemithi, ungqimba asbestos. Uma siqhathanisa nge imvelo bangaphandle, yobunzima yalolu hlobo umphini impela high, okuyinto enomthelela ukuntula kwabo lwezimpawu. Konke lokhu kungaba ukwandisa nokwethenjelwa wabo ukusebenza bese kukhuphula ukusebenza ngendlela.

Shut-off valve phezu kwamanzi: Ngokungafani ukuguqulwa entsha ubudala

Umklamo walolu hlobo ukuqinisa kakhulu washintsha, ukuze ukwazi ukulandelela umehluko obalulekile eziningana. I izici ezibaluleke kakhulu nokulungiswa entsha yilezi:

• anda ukumelana ukungcoliswa;
• kusezingeni anda ubuqotho;
• Ukuthembeka luyanda ngangokunokwenzeka;
• isivinini impendulo idlula ukuguqulwa ubudala;
• umugqa zinto zingase zicishe zifane ngezindlela ezimbili: phambili futhi ukuhlanekezela.

Lolu hlobo lwe-valve ngokuvamile sisetshenziswa amandla isizukulwane, uginindela nephepha nokudla izimboni, kanye nokwelashwa kwamanzi kanye nokulungiselela yayo.

Okudingekayo nokufakwa livaleke-off

Le mfuneko esemqoka kulokhu ijubane impendulo. Ukuhambisana nale ibangelwa kuhlomisa entwasahlobo valve noma ngaphezulu. Ngokuvamile ku imiklamo efana, sebenzisa ikhoyili iziphethu noma Belleville. Uma usebenzisa ugesi actuator valve design kusikisela ukuba khona latches ukuthi ubambe entwasahlobo isimo cocked, futhi kubo ilawulwa electromagnets. Okuzenzakalelayo livaleke-off valve kwabangela kweso futhi vele uye ngokushesha ku-standby mode uma kunesidingo.

Zonke izinhlobo yalolu hlobo ukuqinisa zingenziwa ngezinto ezahlukene: steel, plastic, yensimbi waphonsa noma insimbi engagqwali.
