Mpira vavu china chotulutsa: kapangidwe ndi ntchito

Mpira mavavu kutumikira mavavu monga chitsekere-kuchokera pa mapaipi panja (mpweya ndi mafuta mapaipi, mapaipi oyang'anira tauni misewu, mapaipi, mankhwala zachiwawa ndi moto woopsawo mafakitale, etc.). kusintha limodzi la valavu mpira ndi mpira vavu china chotulutsa.

Izo ntchito monga chipangizo lanu kuti ndigwire kwathunthu otaya sing'anga kufalitsidwa payipi ya. Chotero sing'anga angakhale mafuta ndi mankhwala ake, madzi, gasi, mpweya, mankhwala mowa zina zachilengedwe aukali.

Mtundu wa Kireni amakhala mu kuti chikugwirizana ndi ngalande ndi kuwotcherera. Mpira vavu china chotulutsa alibe mbali detachable (flanges, couplings ndi zina zotero), ndipo izi zipangitsa kuti kachulukidwe pazipita pawiri ndi minimization wa kuchucha mu malo.

Gawo

Mpira mavavu kwa kuwotcherera ali m'magulu malinga ndi mtundu wa pagalimoto:

• dzanja;
• kukhala ndi actuator (chopangidwa pa dongosolo lapadera kulola kuti payipi ya);
• Dzanja ndi zida;
• kukhala actuator pneumatic (chopangidwa pa dongosolo lapadera kulola kuti ngalande za).

Childs, Buku mpira vavu ntchito kuwotcherera ndi miyeso ochepa a ndime, ndi kuthamanga otsika kapena sing'anga mu ngalande ndi. Ngati kuthamanga mu chitoliro pamwamba avareji, pokhala iwo eni wokha mapaipi a m'mimba mwake lalikulu kapena sing'anga, ndi bwino ntchito Crane ndi valavu magetsi kapena pneumatically actuated.

Komanso, valavu mpira akhoza welded ndi zonse zinabala nepolnoprohodnym (wachinsinsi ndi mtundu wa ndime).

Kupanga ndi kapangidwe ka valavu mpira

Zigawo za mavavu nyumba mpira chopangidwa ndi kuwotcherera (kugwirizana kukhala cholimba ndi odalirika). Momasuka akuyandama mpira wosindikiza mpando wa PTFE.

Mu kupanga luso pachiyambi. Mbali yaikulu ya chipangizo ndi zitsulo kuumbidwa nyumba. Pa kupanga loyamba anasonkhana potseka njira, ndipo kenako anakaliika mu thupi. Mipope mosamala scald.

Chifukwa ndi kapangidwe yopindika, omwe sayenera kukonza.

Mpira vavu zitsulo china chotulutsa ali wapadera kapangidwe mkati. Pankhani ya zomangamanga iyi avale ndondomeko yokha compensates. Izi ntchito ndi mipira Tiyeni tiziyesetsa amene anakonza pakati pa akasupe, kukhala sealant. Ngati inu kuvala chidutswa chimodzi, kasupe zambiri ndipo zikugwirizana zonse kapangidwe komanso mwamphamvu. Izi zipangitsa zikayamba mpaka kalekale.

Opaleshoni kukonzanso

1. Mpira vavu kwa kuwotcherera ayenera opareshoni pa kutentha osachepera 30 ° ^C.

2. Anzanu mu payipi mwina 1.6 / 2.5 / 4 megapascal.

3. sing'anga kufalitsidwa ayenera kukhala yoyenera kutentha: osiyanasiyana kuchokera -35 kuti +180 ° ^C.

kukonza zonse ndi kukonza zodula zipangizo osafunika. Nokha, inu mukhoza kuwonjezera chidindo tsinde la. Development wa kamangidwe sasamalira kukonza kapena m'malo mbali pa nthawi yonse imene ntchito.

Ubwino ndi kuipa kwa mavavu mpira kwa kuwotcherera

ubwino:

• zochepa kulemera;
• mtengo wotsika;
• vavu akutsegula mwamsanga ndipo mosavuta;
• ntchito Kireni n'kupita patsogolo sumangoyambika mu dera kumene madzi uyenda;
• wangwiro, yodalirika ndiponso yosavuta kamangidwe;
• madzimadzi zolimba shutoff;
• vavu Izi waikidwa mu kwambiri udindo ndi kovuta kuti akafike kudera la payipi ya;
• palibe yokonza chofunika.

kuipa:

• kukonza sizingatheke;
• kukhala ndi kusintha valavu zitha kukhala ndi ntchito kuwotcherera;
• kuthekera nyundo madzi pa kutsegula mwadzidzidzi Crane ndi;
• anachitazi ntchito chifukwa cha yaitali ndalezo mpopi alipo (pamene ntchito zinthu yochepetsetsa).
