Waa maxay shahaadada valve ws?

Wras (Qorshaha La-Talinta Qawaaniinta Biyaha) Shahaadaynta waxaa lagu soo bandhigay Boqortooyada Ingiriiska 1998.

Waxaa loo aasaasay si loo hubiyo in alaabadaas (fiilooyin / tuubooyin / ku habboon…) Loo adeegsaday nidaamyada biyaha, Waa inuu buuxiyaa heerarka ay dejiyeen bixinta biyaha (Ku rakibayaasha biyaha) Xeerar 1999 iyo biyihii biyaha ee Scottish-ka. Qorshahan waxaa maamula Nidaamka La-Talinta Xeerarka Biyaha, shirkad ay leedahay warshadaha biyaha ee Boqortooyada Midowday.

Sida loo xaqiijiyo shahaadada Valve Wras?

Tallaabo qaadid 1: Helitaanka tusaha ansixinta On Online

• Booqo websaydhka Websaydhka: Tagwww.wrasapprovals.co.uk
• U gudub “Tusaha Ansixinta Ansixinta”: Gubid “Tusaha Ansixinta Ansixinta” Laga soo bilaabo liiska.
• Raadi shahaadada:
  • Ikhtiyaar 1: GaliLambarka shahaadada WRS (E.g., 2309345) ee bar baaritaanka.
  • Ikhtiyaar 2: Raadi byMagaca shirkadda(E.g., Ningbo ugu fiican m&CO., Ltd.), Nooca Wax soo saarka, ama(sasho Haddii lambarka shahaadada aan la heli karin.

Tallaabo qaadid 2: Hubso faahfaahinta shahaadada

Markaad hesho shahaadada tusaha, Xaqiiji faahfaahinta soo socota:

1. Lambarka shahaadada: Hubso inay la mid tahay nambarka lagu siiyay shahaadada jirka / dhijitaalka ah.
2. Magaca shirkadda: Xaqiiji shirkadda ku taxan inay tahay soo-saaraha ama alaab-qeybiyaha sheyga.
3. Sharraxaadda Wax soo saarka: Hubi haddii badeecada / magaca Moodelka ay la jaan qaadayaan shayga aad caddeynayso.
4. Taariikhaha ansaxnimada: Shahaadooyinka Qoraalka ayaa ansax ah5 sanado. Hubso in “Ansax ka” iyo “Taariikhda dhicitaanka” waa hadda.
5. Nooca ogolaanshaha: Hubso haddii ay tahayAnsixinta badeecada amaAnsixinta maaddada (Qalabka aan caadiga ahayn).

Tallaabo qaadid 3: Hubi ka eeg sheybaarka la soo saaray

• Shahaadooyinka Qoraalka waxaa soo saarayShaqaalaha sheybaarka loo aqoonsan yahay UKAs (E.g., WRC-NSF, Buusashada). Si toos ah ula xiriir shaybaarka haddii shaki laga qabo shaki:
  • Email sheybaarka: Provide the certificate number and request confirmation (e.g.,info@wrcnsf.com for WRc-NSF).
  • Verify lab credentials: Ensure the lab is listed on the UKAS website (www.ukas.com).

Tallaabo qaadid 4: Kormeer Shahaadada Jirka / Dijitaalka ah

• Check security features:
  • Holographic seal: Genuine certificates include a WRAS hologram.
  • QR code: Scan the QR code (if present) to redirect to the official WRAS directory entry.
  • Authorized signatures: Ensure the WRAS approvals manager signs the certificate.
• Look for inconsistencies:
  • Misspellings, blurry logos, or incorrect UKAS accreditation numbers.

Waa maxay dhinacyada ay ku qoran doonaan tuubooyinka shahaadada leh?

1. Material Safety
   • Nickel-plated brass construction to prevent leaching of lead and other harmful substances, compliant with drinking water safety standards (E.g., BS 6920, NSF/ANSI 61).
2. Pressure Ratings
   • Different sizes correspond to varying pressure ratings, E.g., PN16 to PN40 (E.g., PN40 for 1/4″–1″, PN25 for 21/2″–3″).
3. Temperature Range
   • Ka shaqeynta dulqaad0° C illaa 120 ° C, oo leh shuruudo wax qabad gaar ah oo ku saabsan xaaladaha heerkulka-sare (E.g., ≤0.15 m³ / h oo ka soo baxa 650 ° C for 30 Daqiiqadaha Nabadgalyo Nabadgalyo).
4. Naqshadeynta qaab dhismeedka
   • Naqshad buuxda (yareynta caabbinta socodka), ka hortagga stem (Waxay ka hortagtaa in laga qaado qaybaha), oo kor u qaadaya habab xirxiran (E.g., Miraha qanjirka la isku hagaajin karo, Kuraasta PTFE).
5. Xaaladaha Codsiga
   • Heerarka cadaadiska cadaadiska ee kala duwan eegaaska vs. Codsiyada gaaska (E.g., 5 Gas, 25 Bar oo gaas ah). Kala duwanaansho gaar ah oo loogu talagalay isticmaalka kiimikada / warshadaha (E.g., PTFE-SENDES FARSAMADA SAXIIXA CAAFIMAADKA).
6. Heerarka Tijaabada
   • Xaqiijinta Awoodda Awoodaha (Gudaha 331 si loogu adkeysto gaaska gaaska), Tijaabada sheyga aan sunta lahayn (BS 6920), iyo shahaadada daminta dabka (E.g., AteEx / CPR).

Waa maxay sababta caddeynta valle wrass ay muhiim u tahay?

Shahaadada Wras waa qasab ku ah nidaamyada biyaha ee Boqortooyada Midowday.

Hay'adda shahaadiyaha ee WBR waxay u baahan tahay qalabyo biyo oo tayo sare leh iyo qalab ah. Hagaajin, tuubbo, iyo qalabka wax lagu dhejiyo waa in lagu qoraa nabadgelyada iyo waxqabadka.

Shahaadada WBAG ee ku saabsan tuubooyinka

Qaar badan oo ka mid ah alaabooyinka 'Bmaag's VAMAG' ayaa helay shahaadada Wrar, lugu daro:

• Warqadaha la oggolaaday
• Wras la oggolaaday tuubbooyin qufulan oo qufulan
• Wras isku dheelitirka la oggolaaday
• WRS VORONESED BRONEVES BRONEVES
• Wras la oggolaaday tuubooyinka aan soo celin
• WRS Vals Stops Street
• WRS ayaa oggolaatay y-strainers

Tani waxay muujineysaa xoogga awooda waxsoosaarka BMAG iyo tayada wax soo saarka, Waxaan naga dhigay lammaane la isku halleyn karo oo wada shaqeynta.Nala soo xiriir xigasho.
