Flange gedhi vharafu ivhavha yegedhi ine flange yekubatanidza, iyi nzira yekubatanidza ndiyo yakajairika. Flange gedhi mavharuvhu akatsiga uye akavimbika kana ashandiswa mapaipi, saka flange gedhi mavharuvhu anowanzo shandiswa mumapaipi akanyanya-kudzvanywa.

Kana iyo flange gedhi vharafu yakavharwa, nzvimbo yekuisa chisimbiso inogona kungovimba nepakati pekumanikidza kuvhara, ndiko kuti, kuvimba nepakati pekumanikidza kudzvanya nzvimbo yekuisa chisimbiso chegedhi kuchigaro chevhavha kune rumwe rutivi kuti ive nechokwadi chekuisa chisimbiso. nzvimbo yekuisa chisimbiso, iyo inozvisunga. Mazhinji mavharuvhu emagedhi anoshandisa chisimbiso chekumanikidzirwa, ndiko kuti, kana vharuvhu yakavharwa, gedhi rinofanira kumanikidzirwa kurwisana nechigaro nechisimba chekunze kuti ive nechokwadi chekuisa chisimbiso chekuvhara.

Gedhi revharuvhu regedhi rinofamba zvakatevedzana netsinde revharuvhu, iro rinonzi rinosimudza hunde gedhi vharuvhu (inonziwo rising stem gedhi vharafu). Kazhinji pane tambo ye trapezoidal padanda rekusimudza. Kuburikidza nenati iri pamusoro pevharuvhu uye gwara regirovha pamutumbi wevharuvhu, iyo inotenderera inoshandurwa kuita mutsara wekufamba, ndiko kuti, torque yekushanda inoshandurwa kuita basa rekushanda.

Kana iyo valve yakavhurwa, apo kusimudza kukwirisa kwegedhi kwakaenzana ne1: 1 nguva yevhavha yevhavha, nzira yemvura inenge isina kuvharwa zvachose, asi nzvimbo iyi haigoni kuongororwa panguva yekushanda. Mukushandiswa chaiko, iyo yepamusoro yevhavha stem inoshandiswa sechiratidzo, ndiko kuti, nzvimbo iyo isingagoni kuvhurwa, senzvimbo yayo yakazaruka zvakakwana. Kuti utarise chiitiko chekuvhara nekuda kwekushanduka kwekushisa, vharafu inowanzovhurwa kune apex chinzvimbo uye yozodzoserwa kumashure ne 1/2 kusvika 1 kutendeuka seyakazara yakazaruka valve nzvimbo. Nokudaro, nzvimbo yakazaruka yevhavha inotarirwa nenzvimbo yegedhi (kureva stroke>.

Mune mamwe mavharuvhu egedhi, stem nut inogadzika pagedhi, uye kutenderera kwegumbo remaoko kunotyaira kutenderera kwechitsigiro chevhavha kusimudza gedhi. Rudzi urwu rwevharuvhu inodaidzwa kuti vheruvha yegedhi rinotenderera kana kuti vharafu regedhi rakasviba.

Kuiswa kwevhavha yegedhi reflange:

1. Tarisa mukati mevhavha yevhavha uye chisimbiso chepamusoro usati waiswa, uye hapana tsvina kana jecha zvidimbu zvinobvumirwa kunamatira;

2. Mabhoti echikamu chimwe nechimwe chekubatanidza achasimbiswa zvakaenzana;

3. Chengetedza zvikamu zvekutakura kuti zviomerwe zvakasimba, kwete chete kuti uone kusimba kwekutakura, asiwo kuve nechokwadi chekuzarura kushanduka kwegedhi;

4. Usati waisa valve, mushandisi anofanira kutarisa muenzaniso wevhavha, saizi yekubatanidza uye teerera kune kuyerera kwemukati kuti ave nechokwadi chekuenderana nezvinodiwa zvevhavha;

5. Pakuisa valve, mushandisi anofanira kuchengetedza nzvimbo inodiwa yevhavhavhavhavha;

6. Iyo wiring yedhiraivha yedhiraivha inofanira kuitwa maererano neiyo wiring diagram;

7. Ivhavha yegedhi inofanira kuchengetedzwa nguva dzose, uye hapana kudhumhana kana kusvina kunobvumirwa kudzivisa kukanganisa chisimbiso.
