Mfundo yogwirira ntchito ndi kapangidwe ndi malo oyika valavu ya gulugufe yokhala ndi rabara

Thevalavu ya gulugufe yokhala ndi mphirandi mtundu wa valavu yomwe imagwiritsa ntchito mbale yozungulira ya gulugufe ngati gawo lotsegulira ndi kutseka ndipo imazungulira ndi tsinde la valavu kuti itsegule, kutseka ndikusintha njira yamadzimadzi.valavu ya gulugufe yokhala ndi mphiraimayikidwa mbali ya m'mimba mwake ya payipi. Mu ngalande yozungulira yavalavu ya gulugufe yokhala ndi mphiraThupi lake, mbale ya gulugufe yooneka ngati disc imazungulira mozungulira mzere, ndipo ngodya yozungulira imakhala pakati pa 0° ndi 90°. Ikazungulira mpaka 90°, valavu imatsegulidwa kwathunthu.

Malo omangira ndi kukhazikitsa

1. Malo oyika, kutalika, ndi komwe kutumizidwa ndi kutumizidwa kunja ziyenera kukwaniritsa zofunikira pa kapangidwe kake, ndipo kulumikizana kuyenera kukhala kolimba komanso kolimba.

2. Pa mitundu yonse ya ma valve amanja omwe amaikidwa pa payipi yotenthetsera kutentha, chogwiriracho sichiyenera kukhala pansi.

3. Kuyang'ana kowoneka bwino kuyenera kuchitika valavu isanayikidwe, ndipo dzina la valavu liyenera kukwaniritsa zofunikira za muyezo wadziko lonse wa "General Valve Mark" GB12220. Pa valavu yomwe mphamvu yake yogwira ntchito ndi yoposa 1.0MPa ndipo imagwira ntchito yodula chitoliro chachikulu, mphamvu ndi mayeso ogwirira ntchito ziyenera kuchitika isanayikidwe, ndipo imaloledwa kugwiritsidwa ntchito mutapambana mayesowo. Pa mayeso a mphamvu, mphamvu yoyesera ndi yowirikiza ka 1.5 kuposa mphamvu yowirikiza, ndipo nthawi yake si yochepera mphindi 5. Chosungira ndi kulongedza valavu ziyenera kukhala zoyenerera popanda kutayikira. Pa mayeso okhwima, mphamvu yoyesera ndi yowirikiza ka 1.1 kuposa mphamvu yowirikiza; mphamvu yoyesera iyenera kukwaniritsa zofunikira za muyezo wa GB50243 panthawi yoyeserera, ndipo pamwamba pa kutseka valavu pa disc payenera kukhala zoyenerera ngati palibe kutayikira.

Malo osankhidwira zinthu

1. Magawo akuluakulu olamulira avalavu ya gulugufe yokhala ndi mphirandi specifications ndi miyeso.

2. Itha kugwiritsidwa ntchito pamanja, pamagetsi kapena ndi zipu, ndipo imatha kukhazikika pa ngodya iliyonse mkati mwa 90°.

3. Chifukwa cha shaft imodzi ndi mbale imodzi ya valavu, mphamvu yogwirira ntchito ndi yochepa, ndipo nthawi yogwira ntchito ya valavu ndi yochepa chifukwa cha kusiyana kwakukulu kwa kuthamanga kwa mpweya ndi kuthamanga kwakukulu kwa madzi.
