Globe Control Valve

Cage Type imwe-Seat Globe Control Valve

Cage Type single-seat Globe Control Valve inotora iyo cage inotungamirwa chimiro uye kudzvanywa kwakaenzana plug. Inokodzera zvikumbiro zvine mwero wakanyanya kusiyanisa kumanikidza. Kuiswa chisimbiso kwakaringana kunotsiva chigaro chepamusoro kuti chishandure chinyakare chegeji chechigaro chevharuvhu chimiro mukeji imwe-seat chimiro. Kuvandudzwa uku kwakawedzera zvakanyanya kirasi yekuvhara yevhavhavha yekeji. Iyo plug inoshandisa iyo yekumanikidza yakaenzana chimiro, kuvhura uye kuvhara simba kwakadzikira uye yepakati pasi pemamiriro ebasa ane yakanyanya mutsauko kudzvanywa inogona kudzorwa kuburikidza yakaderera actuator kusunda. inoshandiswa zvakanyanya pakutonga kwemvura pamapaipi epakati nepakati tembiricha uye yepakati uye yakaderera kudzvanywa kunoda kugadzikana kwakanaka kwesimba. Iine maficha akadai sekuita kwakanaka kwekuisa chisimbiso, yakakwirira inotenderwa mutsauko kudzvanywa, keji inotungamira, hombe inotungamira nzvimbo, yakanaka kugadzikana uye compact chimiro, iyo mota inoona inokurumidza kutsiva kumisikidza pamutsara nekunyanya kugadzirisa, kuchengetedza vashandi uye nguva. Iyo balance plug chimiro inoita shuwa kuti actuator thrust inodiwa ndiyo yakaderera.

Cage Type Double-seat Globe Control Valve

HCB Pneumatic Cage Type Double-seat Globe Control vharafu inotora iyo cage inotungamirwa chimiro uye kudzvanywa kwakaenzana plug. Yakasiyana neCage Type single-seat Type, iyi mhando yevharuvhu yekudzora inotora iyo cage mhando yeviri chigaro chimiro uye inonyanya kushandiswa mumashandisirwo asina zvakanyanya zvinodiwa zvekuvharika. Sezvo inotora chimiro chezvigaro zviviri, uye zviso zviviri zvekuisa chisimbiso zvisimbiso zvesimbi, tembiricha yakawedzera. Iyo plug inoshandisa iyo yekumanikidza yakaenzana chimiro simba rekuvhura uye rekuvhara rakaderera uye midhiya iri pasi pemamiriro ebasa ane yakanyanya mutsauko kudzvanywa inogona kudzorwa kuburikidza yakaderera actuator kusimudzira. lts anoshandiswa zvakanyanya kudzora mvura pamapaipi epakati neakadzika tembiricha uye inoda kugadzikana kwakanaka kwesimba, Iine maficha akadai seakanaka chisimbiso kuita, yakakwirira inotenderwa mutsauko kudzvanywa, keji inotungamira, hombe inotungamira nzvimbo, kugadzikana kwakanaka uye compact chimiro, inogona kukurumidza kutsiva matrims pamutsetse nekunyanya kugadzirisa, kuchengetedza vashandi uye nguva. Iyo balance plug chimiro inoita shuwa kuti actuator thrust inodiwa ndiyo yakaderera.

Multi-gomba Low Noise Control Valve

Pneumatic Multi hole Yakaderera Noise Kudzora Valve inotora iyo sleeve inotungamirwa chimiro uye kudzvanywa kwakadzikama plug.iri yakakwira performance control vharafu ine yakanaka dhizaini kugadzikana kwakakodzera kune yakaoma sevhisi mamiriro. Sezvo mutsauko wacho wakanyanya kukwirira uye kuyerera kwepakati nepakati kwakakwira, ma trims achakukurwa zvakanyanya uye kukuvadzwa uye ruzha rukuru ruchagadzirwa. Naizvozvo, isu tinoshandura yakajairwa hwindo rudzi sleeve mune multichoke sleeve. kune zvinwiwa nzira yekuyerera inowanzokwira-mukati uye yakaderera-kunze, uye akawanda maburi throttling inoita kuti yepakati iite kubonderana mukati meruoko, kuti ipedze simba remukati uye kuderedza kuyerera kwekukurumidza. Kune gasi uye midhiya, mafambiro ekuyerera anowanzo kudzika-mukati uye kumusoro-kunze, kuitira kuti ga yepakati iwane kuwedzera kwevhoriyamu kuseri kwechigaro mushure mekupuruzira nemulti hole sleeve uye kudzvanywa kwepakati kunoderedzwa kudzikisa kuyerera kwevelocity. Zvikamu zveiyi mhando yekudzora vharafu zvinochinjika neaya eCage Type single seat Control Valve kunze kwekuti sleeve inoshandurwa kuita Mult-hole type.
Multi-Stage Pressure inodonha yekudzora vharafu

Multi-stage Pressure drop control valve inotora iyo sleeve inotungamirwa chimiro uye kudzvanywa kwakaenzana plug. inonyanya kushandiswa mumamiriro ekushandira ane high differential pressure uye zvikumbiro zvinobudisa flash evaporation uye cavitation. Zvinoenderana neakasiyana ma paramita, akagadzirwa aine akasiyana dhizaini anodonhedza makeji ayo anoumba Multi-stage pressure drop drop trim. Makoji akagadzirwa maererano nemamiriro akasiyana-siyana ebasa anovimbisa kuitika kwekukurumidza evaporation uye cavitation mukukosha kunobviswa. Kupuruzira kunoitwa kubva panguva iyo iyo yepakati inobata keji yekutanga, uye iyo yakakwira yekusiyanisa kudzvinyirirwa painopinza inoderedzwa zvishoma nezvishoma mushure menguva dzinoverengeka dzekupuruzira. Nokudaro zvinonyatsosimbiswa kuti kudzvinyirira kunogara kuri pamusoro pemhepo yakasvibiswa apo iyo yepakati inoyerera muvhavhavha, uye kuitika kwekuputika kwemhepo uye cavitation kunobviswa, kuitira kuti hupenyu hwebasa rekutarisa kwekutonga hurebe pasi pemamiriro ezvinhu akaoma.

Cavitation chikonzero uye mhinduro

Kana mhepo yemvura yakaderedzwa kusvika kune yakazara mhute pressure kana pasi, flash evaporation kana mabhubhu zvichaitika.mumavharuvhu akawanda ekudzora mufananidzo 5), inlet pressure is p1, velocity is V1. Kana iyo mvura inopfuura nepanzvimbo yeplug necking, kukurumidza kunowedzerwa kuVvc Maererano nemusimboti wekuchengetedza simba, iyo fluid pressure inodonha kamwe kamwe kuPvc. Kana Pvc yakaenzana kana kushoma pane iyo mvura yakazara mhute kumanikidza Pv, iyo mvura inogadziriswa gasified uye mabhuru anogadzirwa, kuitira kuti flash evaporation iitike. Mushure mokunge mvura ichipfuura nepapogi, kumanikidzwa kunotanga kudzorerwa uye simba rekinetic rinotamirwa kune simba ringagona zvakare Kana kudzvinyirirwa kunodzorerwa kumhepo yakadzika, iyo inoratidzwa se p2 uye velocity iV2. Kana iyo yakadzoreredzwa dzvinyiriro inodarika iyo yakazara mhute kumanikidza Pv, mabhuru akaumbwa achatyoka uye cavitation ichaitika. Rudzi urwu rwekuburitswa kwesimba ruchawedzera kushushikana kwechidimbu kuve pamusoro pe200000psl (1400MPa) uye kushushikana kunoparadza nekukurumidza plug yakasimba.

Mhinduro kune Cavitation

Iyo labyrinth control valve inogona kunyatsobvisa kukuvadzwa kunokonzerwa nekutadza kutonga kweiyo fluid velocity. Kutanga, zvinwiwa zvinoparadzirwa mumatanho maduku akawanda ekuyerera. Nokudaro, kunyange kana mabhuru akaumbwa, huwandu hwavo hwakanyanya kuduku uye simba harina kukwana kubudisa kushungurudzika kunogona kukuvadza zvinhu, chechipiri, kuyerera kwevelocity kunochengetedzwa panzvimbo yakaderera. Saka, chidimbu chekumanikidza hachizodzikiswa kuti chive chakaderera pane iyo fluid vaporizing pressure. Saka, cavitation haizoitiki. Kukuvadzwa kunokonzerwa ne cavitation chiratidzo chinoratidza kukundikana kwekutonga kwekuyerera kwevelocity. Sezvambotaurwa pamusoro apa, kugamuchirwa kwezvinhu zvekuoma kwepamusoro, kuvhara sleeve kana pasi pasi kunongobvisa zvishoma zvishoma zvikanganiso muvhavha inokonzerwa ne cavitation. Iyo yakakwira yakaderera velocity ichakonzera cavitation uye kukuvadza plug, uye mhinduro kune cavitation ndeyekutora labyrinth cage sezvakaratidzwa mumufananidzo.
