Zvaunofanira Kuziva Nezve AWWA Butterfly Valves

Kana zvasvika pakuvaka zvivakwa zvemvura, kugadziriswa kwemvura yakasviba, uye masisitimu emapaipi emakanzuru, mhando shoma dzemavharuvhu dzinovimbika uye dzinoshandiswa zvakanyanya seVharuvhu yeshavishavi yeAWWA. Anozivikanwa nekushandisa kwavo zvakanaka, nyore kushandisa, uye hupenyu hurefu hwebasa, mavharuvhu aya anoita basa rakakosha mukudzora kuyerera kwemvura mumasisitimu emvura ane dhayamita hombe. Asi chii chinoita kuti asiyane nevamwe, uye unosarudza sei rakakodzera kushandisa?

Muchinyorwa chino, tichakurukura zvese zvaunoda kuziva nezvazvoMavharuvhu eshavishavi eAWWA—kubva pamitemo nekuvaka kusvika kumashandisirwo uye mazano ekusarudza zvakakosha.

1. Chii chinonzi AWWA Butterfly Valve

An Vharuvhu yeshavishavi yeAWWAimhando yevharuvhu inotenderera kwekota yakagadzirirwa kudzora kana kuparadzanisa kuyerera kwemvura, kunyanya mumabasa emvura nemasisitimu emvura yakasviba. Chidimbu chekuti "AWWA" chinomiririraSangano reAmerican Water Works, iyo inoisa mwero wekugadzira, kugadzira, uye mashandiro emavharuvhu anoshandiswa mumasisitimu emvura emakanzuru nemaindasitiri.

Chinonyanya kutaurwa nezvemavharuvhu aya ndechekutiAWWA C504, iyo inotsanangura zvinodiwa zvemavharuvhu eshavishavi ane rabha kubva pahupamhi hwemasendimita matatu (75mm) kusvika pahurefu hwemasendimita makumi manomwe nembiri (1800mm).

2. Zvinhu Zvikuru zveAWWA Butterfly Valve

1. Kushanda Kwekota Yekutendeuka
   Dhisiki iyi inotenderera nemadhigirii makumi mapfumbamwe kuti ivhure kana kuvhara nzira yekuyerera, zvichiita kuti ishande nekukurumidza uye ideredze kumanikidzwa zvishoma.

2. Akagara Akashinga
   Mavharuvhu aya anoshandisa zvigaro zverabha kana elastomeric kuti ave nechokwadi chekuti zvinovharwa zvakasimba uye kudzivirira kubuda kwemvura, kunyangwe mushure mekushandisa kwenguva refu.

3. Kuramba Kuora
   Kupfeka kwemukati nekunze (kazhinji epoxy) kunodzivirira muviri wevharuvhu nedhisiki kubva mukuora mumvura ine simba.

4. Dhizaini Yakamanikana
   Kana tichienzanisa nemavharuvhu egedhi, mavharuvhu eAWWA butterfly akareruka uye haatore nzvimbo yakawanda, izvo zvakanaka pakuiswa kwakasimba.

5. Hupenyu Hurefu hweBasa
   Kana mavharuvhu aya achigadziriswa zvakanaka, anogona kugara kwemakumi emakore, kunyanya kana mvura yakachena ichishandiswa.

3.AWWA C504 VS AWWA C516

Panguva iyoAWWA C504inovhara mavharuvhu eshavishavi akajairika ane rabha, itsvaAWWA C516keromavharuvhu eshavishavi anoshanda zvakanyanya (HPBVs), izvo zvakakodzera kushandiswa kwakanyanya uye zvinoda simba rakawanda.

4. Maitiro Ekusarudza Vharuvhu YeAWWA Butterfly Yakakodzera

1. Saizi yepombi uye Kuyera Kumanikidzwa
   Enzanisa saizi yevharuvhu nekirasi nezvinodiwa nesystem. Mavharuvhu eAWWA anowanikwa mumhando dzakasiyana dzepressure (semuenzaniso, 150A, 150B).

2. Midhiya Yebasa
   Simbisa kuti zvinoenderana nemvura, mvura yakasviba, kana zvimwe zvinwiwa.

3. Mamiriro Ekushanda
   Ongorora tembiricha, kumanikidzwa, uye kana zvichidikanwa kudhonza kana kupatsanura.

4. Kuguma Kwekubatana
   Mavharuvhu eAWWA butterfly anowanikwa ane magumo akapinza, akakombama, kana kuti ane michina.

5. Nzira yeKushanda
   Sarudza pakati pekushandisa giya remaoko, ma actuator emagetsi, pneumatic kana hydraulic systems zvichienderana nezvinodiwa nesystem automation.

6. Zvitupa
   Iva nechokwadi chekuti vharuvhu inoenderana nezvinodiwa neAWWA, uye kana ikashandiswa mumasisitimu emvura inonwiwa, inofanira kunge yakasimbiswa neNSF 61.
