Chekutanga,Chii chinonzi Check Valves, tsanangudzo yevhavhavhavhavha.

Cheki vharafu inoreva kuvimba nepakati pachayo kuyerera uye otomatiki kuvhurika uye kuvhara valve disc, inoshandiswa kudzivirira midhiya kudzoka kwevhavha,

anozivikanwawo seimwe nzira inoyerera valve,vharafu isina kudzoka , uye vharafu yekumanikidza kumashure. Cheki vharafu imhando yeotomatiki valve, basa rayo guru nderekudzivirira kuyerera kwepakati, kudzivirira pombi uye mota yekutyaira kubva pakudzokera kumashure, uye kuburitswa kwemukati memudziyo. Cheki mavharuvhu anogona zvakare kushandiswa kudyisa mitsara umo kudzvanywa kunogona kukwira kudarika kudzvanywa kwehurongwa.

 

Chechipiri, iwo akakosha mapoinzi ekutarisa valve kuvaka uye kuisirwa:

1, nzvimbo yekuisa, kureba, kupinza uye kutumira kunze kutungamira kunofanirwa kuzadzisa zvinodiwa nedhizaini, teerera kune kutungamira kwepakati kuyerera kunofanirwa kuenderana negwara remuseve wakatarwa nemuviri wevharuvhu, kubatana kunofanirwa kuve kwakasimba uye kuvharika.

2, vharafu inofanira kuongororwa isati yaiswa, valve nameplate inofanira kusangana nemitemo yenyika iripo. Nokuda kwevhavha iyo kushanda kwayo kwakakura kudarika 1.0MPa uye inobata basa rekucheka pane pombi huru, simba uye muedzo wakaoma wekushanda unofanirwa kuitwa usati waiswa, uye valve inokwanisa inogona kushandiswa. Muedzo wesimba, kudzvanywa kwebvunzo ndeye 1.5 nguva yekumanikidza kwezita, nguva yacho haisi pasi pe5min, goko revharuvhu, kurongedza kunofanirwa kuve kwakakodzera pasina kuvuza. Pakusimba bvunzo, kudzvanywa kweyedzo ndeye 1.1 nguva dzezita rekumanikidza.

3. Usaite cheki yevhavha inotakura huremu mupombi. Mavhavha makuru ekutarisa anofanirwa kutsigirwa akazvimiririra kuitira kuti arege kukanganiswa nekumanikidzwa kunogadzirwa nepipe system.

Chechitatu, Mhosva uye mhinduro

Ⅰ, Kubuda kwemukati

1. Nzvimbo yekuvhara inosungirirwa netsvina.

2. Nzvimbo yekuvhara yakakanganiswa ne hydraulic impact.

3. Bvisa tsvina padhisiki uye pazvigaro zvakavharwa wozvichenesa neparafini.

4. Rework disc uye chigaro kana kutsiva chisimbiso.

Ⅱ, Kubuda kwekunze

Kubvinza pamuviri wevharuvhu uye kubatana kwebhoneti

1. Mabhaudhi ekubatanidza haana kusimbiswa zvakaenzana kana kuti pre-tightening simba harina kukwana.

2. Flange sealing surface yakakuvadzwa.

3. Iyo gasket yakaiswa zvisina kunaka uye yakakuvadzwa kana inokundikana mushure mekushandisa kwenguva refu.

4. Kuenzana simbisa mabhoti uye nuts inobatanidza muviri wevhavha kune chivharo chevhavha.

5. Rework uye kugadzirisa flange chisimbiso pamusoro.

6. Dzorera gasket uye uiise zvakanaka.

Ⅲ, Diski ratsemuka

Iyo yepakati yekumanikidza isati yasvika uye mushure mekutarisa valve inoshanduka, iyo disc inowanzo dhumhana nechigaro, uye disc yezvimwe brittle zvinhu zviri nyore kuputswa.

1. Sarudza ductile material disc.

2. Gadzirisa maitiro ekuderedza kana kudzivisa kudzvinyirirwa kakawanda kusati kwaitika uye shure kwevhavha yekuongorora.
