Kwaandaanya mavalvu

TWS Valvengusikupanga mavalvu uuchibwene. Mumulimo wamavwili wakabambwa kwamyaka iitandila makumi obile. Mazubaano, TWS Valve iyanda kwaambilizya mubufwiifwi kwaandaanya mavalvu.

1. Kwaandaanya kweendelana amulimu akubelesya

(1) vvalavu ya globe: vvalavu ya globe alimwi iizyibidwe kuti vvalavu iijalidwe, mulimo wayo ngwakuswaanganya naa kutyola akati-kati mumupayipi. Chiinga chavalvu yakugela ibikkilizya vvalavu yamulyango, vvalavu yakulesya, vvalavu lyakuzunguluka, vvalavu lyabbola, vvalavu lyabutterfly a vvalavu lya diaphragm, azimwi.

(2)vvalavu yakulanga: vvalavu yakulanga, alimwi iizyibidwe kuti vvalavu yakulanga yomwe naa vvalavu yakulanga, mulimo wayo ngwakukwabilila nzila iili mukati kamupaipi kuti ipiluke. Ivalvu yamunsi ya pompi ya pompi ayalo ili mukkilasi ya check valve.

(3) Valve yakukwabilila: mulimo wa valve yakukwabilila ngwakukwabilila muya uuzwa akati-akati mumupayipi naakuti muchibelesyo kuti utaindi mweelwe wakabikkidwe, kuchitila kuti kuzuzikizigwe makanze aakukwabilila.

(4) vvalavu yeendelezya: vvalavu yeendelezya ibikkilizya vvalavu yeendelezya, vvalavu ya throttle a vvalavu yakugwisya muya, mulimo wayo ngwakubamba muya, kweenda azimwi zintu zili mukati.

(5) shunt valve: shunt valve ibikkilizya misyobo yoonse yamavalvu aakwaabila, azimwi, mulimo wayo ngwakwaabila, kwaandaanya naa kusanganya zintu zili mumupayipi.

(6)vvalavu yakugwisya muya: vvalavu yakugusya muya nchintu chiyandikana loko mumupaipi, eeyo iibelesyegwa kapati mubboila, mukutontozya muya, mumafuta aamuwo, mumapaipi aameenda amupayipi yakugusya maanzi. Kanjikanji zibikkwa mubusena bwakulailila naa mucibuno, azimwi, kutegwa kugwisye muya uuyungizyidwe mumupaipi, kusumpula bubotu bwamugwagwa wamapaipi akucesya kubelesya nguzu.

2. Kwaandaanya kweendelanya akusinikizyigwa

(1) Valve ya Vacuum: chaamba valve iijisi manguzu aakubeleka aali munsi aamanguzu aamuwo.

(2) Ivalvu iijisi muya muniini: chaamba vvalavu iijisi muya uutegwa PN 1.6 Mpa.

(3) Ivalvu yamanguzu aakati-akati: chaamba vvalavu iijisi nguzu zya PN zya 2.5, 4.0, 6.4Mpa.

(4) Ivalvu yamagesi mapati: chaamba ivalvu iilema PN ya 10 ~ 80 Mpa.

(5) Ivalvu iijisi nguzu kapati: chaamba ivalvu iijisi nguzu zya PN 100 Mpa.

3. Kwaandaanya kweendelana akupya kwakubeleka

(1) Ivalavu yakupya loko: ibelesyegwa kupya aakati-akati t <-100°C vvalavu.

(2) Ivalvu yakutontola kusyoonto: ibelesyegwa kupya aakati-akati-100°C t-29°C valve.

(3) Valve yakupya kwachiindi choonse: ibelesyegwa kupya kwaakati aakati-29°C

(4) Ivalvu yakupya kwaakati-kati: ibelesyegwa kupya aakati-kati ka 120°C t 425°C valve

(5) Valve yakupya kapati: ya valve iijisi kupya kwaakati aakati t> 450°C.

4. Kwaandaanya kweendelana anzila yakweenzya

(1) Ivalavu iibeleka alikke chaamba ivalavu iitayandiki manguzu aanze kuti yeendelezye, pesi isyoma manguzu aachintu chili mukati kuti ivalavu yeende. Mbuli vvalavu yakukwabilila, vvalavu yakugwisya muya, vvalavu yakugusya maanzi, vvalavu yakulanga, vvalavu iilanganya zyintu zyoonse, azimwi.

(2) Ivalavu yakubelesya manguzu: Ivalavu yakubelesya manguzu ilakonzya kweenzyegwa aamanguzu aasiyene-siyene.

(3) Ivalvu yamagesi: ivalvu yeendelezyegwa anguzu zyamagesi.

Ivalvu yamuwo: Ivalvu yeendelezyegwa amuwo uusinkilidwe.

vvalavu yeendelezyegwa amafuta: vvalavu yeendelezyegwa amaanzi mbuli mafuta.

Mukuyungizya, kuli kusanganya kwanzila zyakweenzya zili atala aawa, zilimbuli mavalvu aamuwo amagesi.

(4) Ivalvu yamaanza: ivalvu yamaanza alugwasyo lwavwili lyamaanza, janza, lever, sprocket, kuti ibelesegwe a valve. Eelyo chiindi chakujalula vvalavu nichili chilamfu, eechi chintu chakuchelesya vwili a njuka chilakonzya kubikwa aakati kavwili lyamaanza achisiko cha vvalavu. Kuti kakuli kuyandika, ulakonzya kubelesya bbazu lyakujatana lyanyika yoonse antoomwe ashaft yakukwela kuti ubelesye musinzo mulamfu.

5. Kwaandaanya kweendelanya abwamba

(1) Ivalavu nsyoonto: ivalavu iijisi bupati bwa DN 40mm.

(2)Aakativvalavu lyabwamba: vvalavu lijisi bupati bwa DN bwa 50~300mm.valavu

(3)Chipativvalavu lyabwamba: vvalavu lyazina lya DN ndi 350~1200mm vvalavu.

(4) Ivalavu mpati loko: ivalavu iijisi bupati bwa DN 1400mm.

6. Kwaandaanya kweendelanya abupange

(1) Bbuloki vvalavu: chibeela chakujala chili kweenda aakati-kati ka vvalavu;

(2) stopcock: chibeela chakujala nchipulo naakuti bbola, lizungaana akati-kati;

(3) Chiimo chamulyango: chibeela chakujala chileenda aakati kachibbula chavalvu chiimvwi;

(4) Ivalvu yakujula: chibeela chakujala chizinguluka kunze lyachuuno cha valve;

(5) Ivalvu ya Butterfly: disiki lyachibeela chijalilidwe, lizungaana kuzyunguluka ntalisyo muchuuno chavalvu;

7. Kwaandaanya kwiinda munzila yakuswaangana

(1) Ivalvu yakuswaangana iijisi nsinga: mubili wa valve ulaa nsinga zyamukati naa zyaanze, alimwi ulaswaangene a nsinga zya paipi.

(2)Valve yakuswaanganya flange: mubili wa valve uulaa flange, uujatikizyidwe a flange yapayipi.

(3) Valve yakuswaanizya: mubili wa valve ulaa nzila yakuwelda, mpawo iliswaangene akuwelda kwamapayipi.

(4)Wafervvalavu yakuswaanganya: mubili wa valve ulijisi chijatilo, chijatikizyidwe achijatilo chamupayipi.

(5) Ivalvu yakuswaanganya janza: payipi ilijisi janza.

(6) bikka antoomwe vvalavu: kobelesya mabbuluti kujatisya vvalavu amapaipi obile antoomwe.

8. Kwaandaanya kweendelanya azintu zili mumubili wavalvu

(1) Valve yachintu chabutale: mubili wa valve azibeela zimwi zyakabambwa azintu zyabutale. Mbuli vvalavu yabutale, vvalavu yabutale bwakaboni, vvalavu yabutale, vvalavu yamukuba, vvalavu yaaluminiyamu, lead

Ivalvu ya alloy, valve ya titanium, valve ya moner alloy, azimwi.

(2) Valve yazintu zitali zyabutale: mubili wa valve azibeela zimwi zyakabambwa azintu zitali zyabutale. Mbuli vvalavu yapulasitiki, vvalavu yabulongo, vvalavu ya enamel, vvalavu yagilazi, azimwi.

(3) mubili wavalvu wabutale: mubili wavalvu ulimbuli nsimbi, busena bupati bwakujatana aakati-akati mbuvwuntauzi, mbuli vvalavu lyamukati, vvalavu lyapulasitiki lyamukati, bbaaji

Tao valve abamwi.

9. Kweelana akwaandaanya nzila zyakucinca

(1) Kweenda kwamumbali kubikkilizya vvalavu ya bbola, vvalavu ya butterfly, vvalavu ya stopcock, azimwi

(2) Kunyamuna chakugaminina kubikkilizya vvalavu yamulyango, vvalavu yakulesya, vvalavu yakukkala mukkona, azimwi.
