Vhara-kure vharafu mvura uye mvura svikiro

Vhara-kure vharafu chinhu vharafu ane chinangwa ari makasimba igumburwe mutopota rose kana kuti chikamu pamusoro kwesayenzi zvinodiwa kana pakuparwa zvashata. chikuru mukana wayo akurumidze, sapanguva pedyo remvura mudziyo kunouya pakarepo. Cocking chitubu kutakurwa wemagetsi kana pneumatic actuator.

Vhara-kure vharafu: mhuka

Izvi mhando vharafu angava pisitoni kana diaphragm actuator. Uyezve, rakavharwa-kure vharafu anogona kuva mumwe mhando: kukurukurirana, chisina kutsetseka, kuroora kana kaviri chigaro. By nzira nokuvhara ichi mhando chisimbiso ndiko: chirimo, pneumatically, kana electromagnetically lockable mutoro.

kukura

Vhara-kure vharafu ane propulsive muviri kushandiswa anofambisa pulp-hasha kana utachiona runyararo. In mudziyo uyu hapana mira zvikamu. Steel pamwe shutoff vharafu chisina kutsetseka hydraulic pisitoni ane bilateral Chaizvoizvo rinoshandiswa pana refu kumanikidzwa ezvinhu.

Pari, ichi mhando chisimbiso ane vakadaro constructional Mumagazini kuti kudzora svikiro mairi zvikuru nokushingaira kuiswa chiutsi. mumwe vharafu akadaro kusashanda nokuda 1.5-10 seconds. humburumbira kwayo uye pokugara ine gasket, zononoka vanga, zvakaitwa simbi, mumwe ngura nemishonga, pamwe paiva asbestos. Kana tikaenzanisa pamwe kwokunze zvakatipoteredza, tightness kwaiita vharafu zvakakwirira chaizvo, izvo zvinoita kuti nokusava kwavo nemicherechedzo. izvi zvose zvinogona yekudyidzana kuwedzera rakavimbika kwavo nokushanda uye kuwedzera kunyatsoshanda.

Vhara-kure vharafu pamusoro pemvura: Kusiyana itsva nadzurudzo kare

Magadzirirwo kwaiita chisimbiso yekudyidzana achinja, saka unogona chamber kusiyana zvinokosha zvakawanda. Chinonyanya kukosha zvaiva okunatsiridza matsva ndiwo:

• yakawedzera kuramba hutachiona;
• yakawedzerwa chechetere yokuvimbika;
• Kuvimbika ichiwedzerwa napo;
• Kupindura nokukurumidza kwazvo akwegura nadzurudzo;
• mutsetse anogona bindepinde nenzira mbiri: mberi uye harungashandurwi.

Izvi mhando vharafu inowanzoshandiswa simba pazera, pulp uye pepa chikafu Mazinga, uyewo kurapwa mvura uye gadziriro yayo.

Zvinodiwa nokuti rakavharwa-kure Fittings

The chikuru zvinodiwa hazvisi kumhanya akapindura. Zvaidiwa izvi zvinoitwa yokusimbisa vharuvhu chitubu kana kupfuura. Yemanyorero mune mazano akadaro, shandisa coils zvitubu kana Belleville. Kana tichishandisa yemagetsi actuator vharuvhu magadzirirwo presupposes kuvapo latches vanobatisisa chitubu ari cocked ezvinhu, uye kwavari inotongwa electromagnets. Automatic rakavharwa-kure vharafu kunouya pakarepo uye sezvinoita akakurumidza kupinda standby rudzi kana zvakakodzera.

nemarudzi ose kwakadai chisimbiso zvinogona kuitwa Kwakashandiswa micheka: simbi, mapurasitiki, kukanda simbi kana Stainless simbi.
