Ivhavhavha yekumisa, inozivikanwawo sevharuvhu yekuchekwa, ivharuvhu yekumanikidza-kuvharisa uye imhando yevharuvhu yekucheka. Zvinoenderana neiyo yekubatanidza modhi, yakakamurwa kuita mhando nhatu: flange yekubatanidza, threaded yekubatanidza, uye welding yekubatanidza.
Iri rudzi rwevhavha yevhavha yakanyatsokodzera kuvhara kana kudzora uye throttling. Nemhaka yokuti kuvhura kana kuvhara kwevhavha yevhavha yerudzi urwu rwevhavha ipfupi, uye ine basa rakavimbika rekuvhara, uye nokuti kuchinja kwechigaro chechigaro chevhavha kunoenderana zvakananga nekurohwa kwevhavha disc, inonyatsokodzera kugadzirisa kuyerera.
Iyo yekuvhara-vhavha yakagadzirirwa yakaderera inlet uye yakakwira yekubuda, chinangwa ndechekuita kuti kuyerera kupikisa kuve kudiki uye kuchengetedza simba pakuvhura vharuvhu. Panguva imwecheteyo, kana vharuvhu yakavharwa, gasket pakati pevhavha casing uye chivharo chevhavha uye kurongedza kumativi evhavha stem hakuzosimbiswa, uye hazvizoiti pasi pekumanikidzwa uye kupisa kwepakati kwenguva yakareba, iyo inogona kuwedzera hupenyu hwebasa uye kuderedza mukana wekudonha. Mukuwedzera, kurongedza kunogona kuchinjwa kana kuwedzerwa kana valve yakavharwa, iyo iri nyore pakugadzirisa.
Vanhu vazhinji vanofunga kuti valve yekuvhara yakaderera mukati uye yakakwirira kunze, asi haisi. Kazhinji, vharafu yekuvhara yakadzika-mukati uye yakakwira-kunze, asi pane zvimwe zviitiko zvakakosha apo vharafu yekuvhara iri kumusoro-mukati uye yakaderera-kunze:
1. High pressure stop valve ine dhayamita yakakura kupfuura 100mm.
2. Mavharuvhu maviri anovharika akateedzana papombi yekupfuura, yechipiri yekuvharira vharafu inoda "yakakwira inopinza uye yakaderera kubuda"
3. Boiler exhaust uye vent stop valve
4. Electromagnetic inokurumidza-break valve
