Nekufambira mberi kweChina tekinoroji level, mavharuvhu anogadzirwa neChemChina akashandiswawo nekukurumidza, anogona kupedzisa kutonga kwakaringana kwekuyerera, kudzvanywa, mwero wemvura uye tembiricha. Mumakemikari otomatiki kudzora sisitimu, iyo inodzora vharafu ndeyemukuru Iyo actuator, iyo modhi yayo uye kunaka kwechishandiso zvine simba guru pahutano hwemamiriro ekugadzirisa dunhu. Kana kusarudzwa uye kushandiswa kwevhavha yekutonga kusina kunaka, ichatyisidzira zvakanyanya hupenyu hwebasa revhavha inogadzirisa, uye kunyange kana mamiriro acho akakomba, zvinotoita kuti hurongwa huite matambudziko ekupaka. . Nekuvandudzwa kwemaindasitiri otomatiki, iyo pneumatic control valve yakashandiswawo zvakanyanya seyakatanhamara actuator. Rudzi urwu rwevharuvhu yekudzora ine hunhu hwechiito chakavimbika uye chimiro chakareruka. Iine chirevo chakakosha chekuchengetedza kuchengetedzwa kwehurongwa. Inotevera In-yakadzama kuongororwa pakusarudza uye kushandiswa kwepneumatic control valves mukuita kwemakemikari otomatiki control.
1. Kusarudzwa kwepneumatic control valve mukugadzirwa kwemakemikari otomatiki control 1. Kusarudzwa kwemhando yevhavha yekudzivirira uye chimiro kunobva pakusiyana kwekurohwa kwayo. Pneumatic control valve inogona kukamurwa kuita mhando mbiri dzakasiyana, dzinoti straight stroke uye angular sitiroko, zvinoenderana nechimiro Maererano nemapoinzi, pneumatic control mavharuvhu anogona kukamurwa kuva butterfly valves, angle valves, sleeve valves, bhora mavharuvhu, diaphragm mavharuvhu, uye zvakananga-kuburikidza nemavharuvhu echigaro chimwe chete. Zvichakadaro, iyo yakatwasuka-kuburikidza ne-imwe-seat inodzora vharafu ndiyo inodzora vharafu ine kudiki kudonha mukuita kwekushandisa. Basa rekuyerera rakanaka uye chimiro chiri nyore. Inogona kushandiswa munzvimbo dzine zvakakomba zvekuvuza zvinodiwa, asi nzira yekuyerera kwayo ine hutsinye, iyo inorambidzwawo kune imwe nhanho. Kuvandudza chiyero chekushandiswa kwayo. Iyo yakananga-kuburikidza nekaviri-seat control valve ndiyo inopesana neyakatwasuka-kuburikidza ne-single-seat control valve. Hapana chinodikanwa chakasimba chekudonha. Inokodzera kushandiswa munzvimbo dzine hukuru hwekushanda kudzvinyirira kusiyana. Iye zvino, iyo yakatwasuka-kuburikidza nekaviri-seat control valve ndiyo inonyanya kushandiswa muChina. Rudzi rwevharuvhu yekudzora. Sleeve mavharuvhu anogona kupatsanurwa mumhando mbiri, dzinoti kaviri-yakavharwa sleeve mavharuvhu uye imwechete-yakavharwa sleeve mavharuvhu. Sleeve mavharuvhu ane kugadzikana kwakatanhamara, yakaderera ruzha, uye nyore disassembly uye kusangana. Nekudaro, makotesheni avo akakwira uye zvikumbiro zvekugadzirisa zvakare zvakakwirira. Naizvozvo, chiyero chekushandisa chiri pasi pezvimwe zvipingaidzo. Nzira yekuyerera yevharuvhu ye diaphragm iri nyore, uye inogadzira uye inoshandisa PT-FE nePFA ine high corrosion resistance, iyo inonyatsokodzera kushandiswa munzvimbo dzakasimba dzealkali kana dzakasimba asidhi, asi basa rekugadzirisa harina kunaka. 2. Kusarudzwa kwekudzora vharafu mbishi zvinhu Kushandiswa kwemavharuvhu ekudzora kune zvinenge zvakaomarara zvinodiwa pakusaita ngura, chiyero chekumanikidza uye tembiricha. Naizvozvo, mavharuvhu ekudzora emazuva ano anonyanya kushandisa simbi yakakandwa, iyo inogona kunyatso kuvandudza kushorwa kwevhavhavha yekudzora. Uye kumanikidza simba; Stainless steel zvinhu zvinonyanya kushandiswa mune zvakasvibirira zvemukati zvemukati zvevhavhavha yekudzora. Kana iyo system ine yakaderera zvinodiwa pakudonha, unogona kusarudza zvisimbiso zvinyoro. Kana iyo sisitimu iine zvakakwirira zvinodikanwa zvekudonha, unofanirwa kushandisa Hastelloy. Mukusarudzwa kwezvinhu zvinodzivirira corrosion, zvinodikanwa kupfupikisa uye kufunga nezvehuwandu hwemvura, tembiricha uye kudzvanywa, uye kuita sarudzo ine chekuita nekuvhunduka kwemagetsi. 3. Kushanda musimboti uye zvakanakira zvepneumatic control valve (1) Kuongororwa kweiyo nzira yekushanda yepneumatic control valve Ivhavha yenzvimbo uye zvimwe zvikamu zvinogona kupedzisa mhedzisiro yekutyaira valve, uye zvakare inogona kupedzisa kuenzana kwekuchinja, uyezve. shandisa masaini akasiyana-siyana ekudzora kupedzisa kuseta kwepombi yepakati tembiricha, kudzvanywa, chiyero chekuyerera uye mamwe ma paramita. Pneumatic control valve ine hunhu hwekupindura nekukurumidza, kudzora kuri nyore, uye kuchengetedzwa kwemukati, uye hapana chikonzero chekuisa zvigadzirwa zvinoputika. Mushure mekunge kamuri yemhepo iine imwe chiratidzo chekumanikidza, membrane icharatidza kusundirwa, kudhonza ndiro yekurovera, tsinde yevharuvhu, tsvimbo yekusundidzira, chitubu chekumanikidza, uye vheji yepakati kuti ifambe. Mushure mokunge simbi yevhavha yakaparadzaniswa kubva pachigaro chevhavha, mweya wakamanikidzwa uchatenderera. Mushure mekunge chiratidzo chechiratidzo chasvika kune imwe kukosha, valve icharamba iri pakuvhura kunoenderana. Pneumatic control valve ine yakakwirira kuvimbika, yakapusa chimiro, uye haizoratidze magetsi spark mukuita basa. Naizvozvo, chiyero chayo chekushandisa chakapamhama, uye chinogona zvakare kushandiswa mumateshi ekufambisa gasi ane kuputika-uchapupu zvinodiwa.
2. Kuongororwa kwemaitiro ekuyerera kwevhavha yekudzora Kuyerera kwemaitiro evhavha yekudzora kunosanganisira kuyerera kwekushanda uye kuyerera kwakanaka. Pasi pemamiriro ekuti mutsauko wepakati pakati pekupinza uye kubuda unogara uripo, kuyerera kuburikidza nevhavha yekuyananisa ndiko kuyerera kwakakodzera. Uku kuyerera kwakanaka kune mutsara wakatwasuka, Parabola, kuvhura nekukurumidza, muzana maitiro. Panyaya yemhando yemamiriro, iyo kemikari otomatiki yekudzora maitiro inonyanya kutsamira pane musimboti wehunhu muripo wekugadzirwa. Kugadzirwa kwegadziriro ine mitemo yakasimba pamusoro pemaitiro evhavha inogadzirisa. Maererano nechinhu ichi, pakusarudza, zvakakosha kuongorora iyo amplification factor yevhavha inogadzirisa. Dzivirira coefficient yekugadzirisa kubva pakuchinja. Panyaya yemaitiro ekuyerera, vharafu yekudzora icharatidza shanduko mukuyerera panguva yekushanda, iyo iri nyore kwazvo kukonzeresa mibvunzo yekudengenyeka. Apo basa guru rekuzarura rinoshandiswa, valve yekudzora ichaita seinononoka, uye iri nyore kwazvo kuratidza kuti kugadzirisa hakusi panguva uye kugadzirisa hakusi nyore. Tichifunga nezvechinhu ichi, iyo linear flow control valve haifanirwe kushandiswa mune system ine shanduko huru.
3. Kuchengetedza paunenge uchiisa chigadziro chekugadzirisa Usati waisa chigadziro chekugadzirisa, chigadziro chekugadzirisa chinoda kuongororwa zvakanyatsonaka uye zvine ruzivo. Mushure mokunge pombi yakanyatsocheneswa, kuiswa kunogona kuitwa. Panguva yekugadzika, zvinodikanwa kuchengetedza yakatwasuka kana yakatwasuka mamiriro. Panguva imwecheteyo, inofanirwawo kugadzirisa mabheji pamberi uye kumashure kwemashure evhavha inogadzirisa kuti ave nechokwadi chekuchengetedzwa uye kugadzikana kwekushanda kwevhavha inogadzirisa. Mukuwedzera, mukugadzirisa kwekuiswa, inofanirwawo kuongorora kuyerera kwekuyerera. Kuti uve nechokwadi chehutano hwechigadzirwa, chigadziro chinofanira kuiswa pasi pemamiriro ekunyanya kunetseka. Izvo zvinodiwawo kuve nechokwadi kuti kureba kweiyo yakatwasuka pombi chikamu mugwara rekupinza rinosangana nezvinodiwa zvekutsanangurwa. Kana kuiswa kwacho kuchida diki-diameter valve, inoda kunyatsoenderana nemitemo yekuronga. Mumamiriro ezvinhu akajairwa, chikamu chepombi chakatwasuka munzira yekubuda chinoda kuva 3 kusvika ku5 yakakura kupfuura dhayamita yevharuvhu. Panguva yekuisa, zvakakosha kusiya nzvimbo yakakwana kuti iite kuchengetedzwa kunotevera uye kushanda, uye kudzora dhayamita yepombi. Paunosarudza nzira yekubatanidza pombi, zvinhu zvakasiyana-siyana zvinokurudzira zvinofanira kupfupikiswa uye kuongororwa. 4. Mukupedzisa, valve yekudzora ndiyo chikamu chikuru chemakemikari otomatiki control loop. Kusarudzwa, chigadziro uye kuchengetedzwa kwevhavha yekudzora ichakanganisa basa remakemikari system. Nokudaro, mutyairi anofanira kunyatsoteerera mazano akakodzera echigadzirwa uye muchidimbu Kuti uongorore marudzi akasiyana-siyana, nguva dzose sarudza valve inodzora. Nekuvandudzwa kwesainzi uye tekinoroji, kemikari otomatiki kudzora kwakaisawo mberi kwepamusoro zvinodiwa pakugadzirisa mavharuvhu. Izvi zvinoda kutsvakurudza kwakadzama pamusoro pekugadzirisa mavharuvhu kuti arambe achivandudza kuvimbika uye kugadzikana kwekugadzirisa mavharuvhu.
