Nheyo Yokutanga
Iyo yekubuda shinikizo inogona kugara ichishandurwa pakati pekumanikidza kudzikisa kukosha kwevharuvhu uye kushoma kukosha mukati meiyo yakatsanangurwa yemhando yekudzvanywa kwechitubu pasina jamming kana abnormal vibration;

Nheyo Yechipiri
Hakufanirwe kunge paine kuvuza kwemavharuvhu akapfava-akavharidzirwa ekudzikisa mukati menguva yakatarwa;kune simbi-yakavharwa kudzvinyirira kudzikisa mavharuvhu, iyo inodonha haifanire kunge yakakura kupfuura 0.5% yekuyerera kwakanyanya;

Nheyo yechitatu
The outlet pressure deviation of the direct-acting type is not more than 20%, and the pilot-operated type is not more than 10%, kana the outlet flow rate of change;

Musimboti wechina
Iyo yakananga-acting mhando yekubuda kwekudzvanya kutsauka kana inlet pressure ichichinja haina kukura kupfuura 10%, nepo kutsauka kwerudzi rwemutyairi wendege hakupfuuri 5%;

Nheyo yechishanu
Kudzvinyirirwa kuseri kwevharuvhu yekudzikisa vharafu kunofanirwa kunge kuri pasi pe 0.5 nguva yekumanikidza pamberi pevhavha;

Nheyo yechitanhatu
Ivhavha yekuderedza kudzvinyirira ine zvakasiyana-siyana zvekushandisa uye inogona kushandiswa pamhepo, yakamanikidzwa mhepo, gasi remaindasitiri, mvura, oiri, uye zvimwe zvakawanda zvemidhiya midhiya michina uye mapaipi.kumiririra kuyerera kwevhoriyamu kana kuyerera;

Musimboti Wechinomwe
Low pressure, diki, uye yepakati dhayamita svikiro svikiro zvakakodzera mabhero akananga anoita kudzvanya kudzikisa vharafu;

Nheyo yechisere
Pakati uye yakaderera kumanikidzwa, svikiro uye diki dhayamita mhepo uye mvura midhiya zvakafanira nhete-firimu zvakananga-kuita kumanikidza kuderedza mavharuvhu;

Principle Nine
Iyo mhepo, mhepo, uye midhiya yemvura yekumanikidza kwakasiyana, madhayamita, uye tembiricha zvese zvinogona kushandiswa nepilot piston pressure yekudzikisa valve.Inogona kushandiswa kune zvakasiyana-siyana zvekuora media kana yakavakwa nesimbi isina asidi-resistant simbi;

Chisungo chegumi
low pressure, yepakati nediki dhayamita chiutsi, mhepo, uye mamwe midhiya akanakira mutyairi wemabhero pressure inodzika vharafu;

Principle Eleven
yakaderera kudzvanywa, yepakati kudzvanywa, diki uye yepakati dhayamita chiutsi kana mvura, uye mamwe midhiya-inoenderana mutyairi firimu kudzvinyirirwavharafu;

Musimboti wegumi nembiri
80% kusvika 105% yezvakatsanangurwavalueyekudzvanywa kwekutora kunofanirwa kushandiswa kugadzirisa dhizaini yekudzikisa vharafu yekupinza kumanikidza kuchinja.Iko kuita panguva yekutanga nhanho dzekuora kunozokanganiswa kana ikapfuura iyi chiyero;

Musimboti Wegumi Nematatu
Kazhinji, kumanikidzwa kuseri kwekudzvinyirira-kuderedzavharafuvharafu inofanira kuva isingasviki 0.5 nguva iyo yakanga iripo pamberi pevhavha;

Musimboti Wegumi Nechina
Iyo yekumanikidza yekudzikisa giya zvitubu zvegiya zvinongobatsira mukati meiyo yakatarwa siyana yekubuda kwemhepo, uye inofanirwa kutsiviwa kana huwandu hwapfuura;
Musimboti 15
Pilot piston type pressure reduction mavharuvhu kana pilot mabhero type pressure yekudzikisa mavharuvhu anowanzo shandiswa kana tembiricha yekushanda yepakati yanyanya kukwira;

Musimboti 16
Inowanzokurudzirwa kushandisa yakananga-yakaita yakaonda-firimu kudzvinyirira kuderedza valve kana mutyairi-anoshanda akaonda-firimu kudzvinyirira kuderedza valve kana svikiro iri mhepo kana mvura (mvura);

Musimboti 17
Kana chiutsi chiri chepakati, vharuvhu yekudzikisa kumanikidza yemutyairi wepiston kana pilot bellows mhando inofanirwa kusarudzwa;

Musimboti 18
Ivhavha yekuderedza kudzvinyirira inofanirwa kuiswa pane yakatwasuka pombi kuitira nyore kushandisa, kugadzirisa, uye kugadzirisa.
