Mune fluid piping system, valve ndiyo inodzora chinhu, basa rayo guru nderekuparadzanisa michina uye pombi system, kudzora kuyerera, kudzivirira kuyerera, kutonga uye kuburitsa kumanikidza.
Mavharuvhu anogona kushandiswa kudzora kuyerera kwemhepo, mvura, chiutsi, akasiyana corrosive media, madhaka, oiri, liquid metal uye radioactive media uye mamwe marudzi emvura.Sezvo iyo pombi system yekusarudza iyo yakanyatsokodzera vharafu yakakosha, saka, kuti unzwisise maitiro evhavha uye kusarudzwa kwematanho evharuvhu uye hwaro hwave hwakakosha.
Kukamurwa kwemavharuvhu:
Imwe, vharuvhu inogona kukamurwa mumapoka maviri:
Rudzi rwekutanga rwevharuvhu otomatiki: vimba nepakati (mvura, gasi) kugona kwayo uye kuita kwayo kwevhavha.
Zvakadai sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhau kadhivhavhavhavhavhavhavhavhavha,rivhavharuvha,rivhavharuvha,kuderedza vharafu zvichingodaro.
Rudzi rwechipiri rwevhavha yekutyaira: bhuku, magetsi, hydraulic, pneumatic kudzora chiito chevhavha.
Zvakadai segedhi vharafu, globe vharafu, throttle vharafu, butterfly vharafu, bhora vharafu, plug vharafu uye zvichingodaro.
Zviviri, zvinoenderana nemaitiro ekugadzirisa, zvinoenderana nekutungamira kwezvikamu zvekuvhara zvine chekuita nekufamba kwechigaro chevharuvhu zvinogona kukamurwa:
1. Chimiro chekuvhara: chikamu chekuvhara chinofamba nechepakati pechigaro;
2. Chimiro chegedhi: chikamu chekuvhara chinofamba nechepakati pechigaro chepamusoro;
3. Jongwe nebhora: chikamu chekuvhara iplunger kana bhora, inotenderera kumativi ayo epakati;
4. Swing shape: zvikamu zvekuvhara zvinotenderera kune axis kunze kwechigaro;
5. Disc: dhisiki yezvikamu zvakavharwa inotenderera kumativi ose echigaro chechigaro;
6. Slide valve: chikamu chekuvhara chinotsvedza munzira inotenderera kune chiteshi.
Vatatu, maererano nekushandiswa, maererano nekushandiswa kwakasiyana kwevhavha inogona kugoverwa:
1. Kupwanya kushandiswa: kunoshandiswa kuisa kana kucheka pombi yepakati, senge globe valve, gedhi vharafu, bhora vharafu, butterfly vharafu, nezvimwe.
2. Tarisa: inoshandiswa kudzivirira kudzoka kwemashure, zvakadai semavharuvhu ekuongorora.
3 regulation: inoshandiswa kugadzirisa kudzvinyirira uye kuyerera kwepakati, zvakadai sekugadzirisa valve, kudzvinyirira kuderedza valve.
4. Kugovera: inoshandiswa kushandura kuyerera kwepakati, kugovera svikiro, senge nzira nhatu jongwe, kugovera valve, slide valve, nezvimwewo.
5 vharafu yekuchengetedza: kana iyo yepakati inomanikidza inodarika kukosha kwakatarwa, inoshandiswa kuburitsa yakawandisa yepakati kuti ive nechokwadi chekuchengetedzwa kwepombi system nemidziyo, sevhavhavhavha yekudzivirira uye vharafu yenjodzi.
6.Kumwe kushandiswa kunokosha: zvakadai sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhashe,sewage valve etc.
7.Four, zvichienderana nekutyaira modhi, zvinoenderana neyakasiyana yekutyaira modhi inogona kukamurwa:
1. Manual: nerubatsiro rwegumbo remaoko, mubato, lever kana sprocket, nezvimwewo, nemotokari yevanhu, tyaira hombe torque fashion worm gear, gear uye imwe deceleration device.
2. Magetsi: inotyairwa nemota kana imwe mudziyo wemagetsi.
3. Hydraulic: Kutyaira nerubatsiro rwe (mvura, mafuta).
4. Pneumatic: inotungamirirwa nemhepo yakamanikidzwa.
shanu, maererano nekumanikidzwa, maererano nezita rekumanikidzwa kwevhavha rinogona kugoverwa:
1. Vacuum valve: absolute pressure < Mavhavha ane urefu hwe 0.1mpa, kana 760mm hg, anowanzoratidzwa ne mm hg kana mm column yemvura.
2. Low pressure valve: nominal pressure PN≤ 1.6mpa valve (kusanganisira PN≤ 1.6mpa simbi valve)
3. Medium pressure valve: nominal pressure PN2.5-6.4mpa valve.
4. High pressure valve: nominal pressure PN10.0-80.0mpa valve.
5. Super high pressure valve: nominal pressure PN≥ 100.0mpa valve.
Nhanhatu, zvichienderana nekupisa kwepakati, zvichienderana nevhavha inoshanda yepakati tembiricha inogona kukamurwa:
1. Ordinary valve: inokodzera kutonhora kwepakati -40 ℃ ~ 425 ℃ valve.
2. High tembiricha vharafu: yakakodzera svikiro tembiricha 425 ℃ ~ 600 ℃ vharafu.
3. Heat resistant valve: inokodzera kutonhora kwepakati pamusoro pe600 ℃ valve.
4. Low tembiricha vharafu: yakakodzera svikiro tembiricha -150 ℃ ~ -40 ℃ vharafu.
5. Ultra-yakaderera tembiricha vharafu: yakakodzera svikiro tembiricha pazasi -150 ℃ vharafu.
Zvinomwe, zvinoenderana nedhayamita yezita, zvinoenderana neiyo dhayamita yevhavha inogona kukamurwa:
1. Diki dhayamita vharafu: zita dhayamita DN <40mm vharafu.
2. Medium dhayamita vharafu: zita dhayamita DN50 ~ 300mm vharafu.
3. Hombe dhayamita vharafu: zita dhayamita DN350 ~ 1200mm vharafu.
4. Yakawandisa dhayamita vharafu: zita dhayamita DN≥1400mm vharafu.
Viii.Inogona kukamurwa zvichienderana nekubatanidza maitiro evhavha uye pombi:
1. Flanged valve: muviri wevharuvhu une flanged, uye pombi ine flanged vharafu.
2. Threaded yekubatanidza vharuvhu: muviri wevharuvhu neshinda yemukati kana shinda yekunze, tambo yekubatanidza vharafu ine pombi.
3. Welded yekubatanidza vharafu: vharafu muviri une welds, uye mapaipi ane welded mavharuvhu.
4. Chivharo chekubatanidza vharafu: muviri wevharuvhu une chirambi, uye pombi yekubatanidza vharafu.
5. Sleeve connection valve: valve yakabatanidzwa ne sleeve uye pipeline.
