Kemikari chirimwa vharafu mhando uye nzvimbo yekushandisa (ine mhando inoshanda)
Mushure mekugadzirwa kweinjini dzeutsi, mumakore makumi maviri kana makumi matatu apfuura, nekuda kwekudikanwa kwemafuta asina kuchena, zvidyarwa zvemakemikari, zvidyarwa zvemagetsi, indasitiri yesimbi, ngarava, kugadzirwa kwemagetsi enyukireya, aerospace uye mamwe minda, zvirinani zvinopihwa zvakaiswa pachena. nokuti mavharuvhu, uye maindasitiri kugadzirwa mavharuvhu vari zvakare siyana mhando.Sevhavhakusuma chemikari chirimwa vharafu mhando yekushandisa saiti uye kushanda kwayo.
A kemikari chirimwa vharafu mhando uye kushandiswa
1. Gadzira zvinoenderana nekubudirira uye ndima yekushandisa
(1) vhara vharafu: vharafu yakachekwa inozivikanwawo setambo yedhijitari TELEVISION vharafu, uye mhedzisiro yayo ndeyekuwana kana kubvisa svikiro mupombi. Mavharuvhu akachekwa anosanganisira mavharuvhu epasi, mavharuvhu epasi, mavharuvhu, mavharuvhu, mavharuvhu edhisiki uye madiaphragms.
(2) cheki vharafu: cheki vharafu inozivikanwawo se throttle vharafu kana cheki vharafu, mhedzisiro yayo ndeye kudzivirira yepakati mupombi kumusoro. Centrifugal pombi hygroscopic kubva papombi yepasi vharafu zvakare ndeye cheki valve kirasi.
(3) vharafu: basa rekirasi yevhavhavha yekudzivirira ndeyekudzivisa kushanda kwepakati mupombi kana midziyo yakakwirira kudarika kukosha kwakataurwa, kuitira kuti uwane chinangwa chekuchengetedzwa kwekuchengetedzwa.
(4) vharafu inogadzirisa: kirasi yevhavha inogadzirisa inosanganisira kugadzirisa valve, imwe nzira yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharevharevhavhavhavhavharevhavhavhavhavhavharevhavhavhavha,zvinoita kuti igadzirise kushanda kwepakati,kuyerera kwese uye mamwe matatu.
(5) vharafu yekuparadzanisa: iyo shunt valve chikamu inosanganisira akasiyana-siyana mavharuvhu uye matepi emhepo, nezvimwewo, mhedzisiro yayo ndeyekutumira, kupatsanura kunze kana kusanganisa yepakati mupombi.
2. Classification by pondo kirasi

4. Gadzira maererano nefomu rekusimudzira
(1) Automatic valve haisi simba rekunze rekusimudzira, asi nesimba repakati pachayo kugadzira nzvimbo yevhavha yevhavha. Zvakadai sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhau kecheki,atomatiki control valve zvichingodaro.
(2) Kutyaira simba rekudzora vharafu: kutyaira simba rekudzora vharafu rinogona kushandisa akasiyana siyana emagetsi ekusimudzira.
Magetsi ekudzora vharafu: kuvimba neinjiniya yesimba kusimudzira vharafu.
Pneumatic valve: vharafu inofambiswa nemhepo compression.
Hydraulic valve: valve inofambiswa nekumanikidzwa kwemvura yakaita semafuta.
Mukuwedzera, kunewo zvikamu zvezvikamu zviri pamusoro apa zvekufambisa nzira, zvakadai segesi-magetsi ekugadzirisa mavharuvhu.
(3) Manual valve: manual valve inobva pane spindle, rocker, rod bar, sprocket chain, nehupfumi hwevanhu kudzora kumira kwevhavha. Kana iyo vharafu yekuvhura uye yekuvhara torque yakakura, vhiri kana worm giya rekudzikisira rinogona kuiswa pakati pechirungu nechigaro. Kana zvichidikanwa, majoini ekadhini uye shafts inotenderera inogonawo kushandiswa kureba kure kushanda kushanda.
5, maererano nezita rekuti dhayamita dhayamita classification

Chechipiri, kemikari chirimwa vharafu kushanda zvakanaka
Vhura uye kuvhara mhando: bvisa kana kutaurira fluidity yemvura mu ac pombi;
Kugadzirisa mhando: gadzirisa huwandu hwekuyerera uye kuyerera kumhanya muchubhu;
Throttle valve mhando: gadzira iyo mvura inoenderana nevhavha mushure mekukonzera yakakura kwazvo gasi kudzvanywa;
Dzimwe mhando: a. zvizere otomatiki kuvhura nekuvhara B. kuchengetedza kumwe kushanda kumanikidza C. chiutsi chinovharira pombi yemvura.
