Rejeleo la Uhandisi

Mchoro wa Vipimo vya Valve ya Lango Mwongozo wa Lebo

Michoro ya vipimo vya valve ya lango hutumia alama na lebo sanifu. Kuelewa lebo hizi huwezesha wahandisi kutafsiri haraka michoro ya kiufundi, faili za CAD, na karatasi za data za mtengenezaji.

Urefu wa Uso kwa Uso / Mwisho hadi Mwisho

Umbali kati ya nyuso za flange au kipimo cha mwisho hadi mwisho kwa valves za butt-weld. Imefafanuliwa kwa ASME B16.10.

Kipenyo cha Nje cha Flange

Kipenyo cha jumla cha ncha ya flange. Lazima ilingane na flange inayolingana kulingana na ASME B16.5.

Kipenyo cha Mduara wa Bolt

Kipenyo cha duara linalounganisha vituo vya mashimo ya bolt kwenye uso wa flange. Muhimu kwa upatanisho wa muundo wa bolt.

Kipenyo cha Uso wa Kuziba

Kipenyo cha uso wa kuziba ambapo gasket hugusana. Muhimu kwa uadilifu wa muhuri.

Urefu wa Jumla

Urefu kutoka katikati ya bomba hadi juu ya gurudumu la mkono au shina la kiendesha. Muhimu kwa upangaji wa nafasi.

Kipenyo cha Gurudumu la Mkono

Kipenyo cha gurudumu la mkono la mwongozo. Kubwa zaidi kwenye madaraja ya juu ya shinikizo kwa faida ya kiufundi.

Kidokezo: Unapokagua mchoro wa valve ya lango, daima thibitisha kuwa urefu wa uso kwa uso (L) unalingana na mpangilio wako wa mabomba, na uthibitishe daraja la flange linaendana na kiwango cha shinikizo cha mfumo wako. Pakua michoro ya vipimo kutoka kwa Xintai Valves au wasiliana na timu yetu ya uhandisi kwa faili maalum za CAD.

Mwongozo wa Uchaguzi

Jinsi ya Kuchagua Sahihi Vipimo vya Valve ya Lango

Kuchagua valve ya lango kunahusisha zaidi ya ukubwa tu—lazima uzingatie darasa la shinikizo, nyenzo, na uendeshaji. Fuata hatua hizi ili kutumia mwongozo huu wa vipimo kwa ufanisi na kutaja valve sahihi kwa programu yako:

①

Thibitisha Ukubwa wa NPS / DN

Linganisha NPS au DN ya valve na bomba iliyoainishwa katika P&ID yako au mchoro wa mpangilio wa bomba. Kuzidisha ukubwa huongeza gharama na uzito; kupunguza ukubwa husababisha kizuizi cha mtiririko.

②

Tambua Darasa la Shinikizo

Rejelea chati ya ukadiriaji wa shinikizo-joto ya ASME B16.34 na uchague darasa linalolingana na hali yako ya uendeshaji wa mfumo. Madarasa tofauti yana ukubwa na uzito tofauti wa flange.

③

Panga Nafasi ya Ufungaji

Valvu za lango zinahitaji kibali cha wima kwa lango lililo wazi kikamilifu, shina, gurudumu la mkono au kiendesha. Tumia kipimo cha H kubuni vibali vya kutosha karibu na vifaa na majukwaa.

④

Chagua Aina ya Uendeshaji

Ukubwa mdogo unaweza kutumia operesheni ya gurudumu la mkono; ukubwa mkubwa au operesheni ya mara kwa mara inahitaji gari la gia. Darasa la 600/900 kwa kawaida huamuru uendeshaji wa gia.

⑤

Chagua Daraja la Nyenzo

Standard applications use A216 WCB (cast steel); low-temperature service use A352 LCC; corrosive service use Stainless Steel 304/316L.

⑥

Obtain Engineering Drawings

After finalizing selection, request complete dimension drawings, 3D CAD models, and weight data from the manufacturer for detailed design and procurement.

Maswali Yanayoulizwa Mara Kwa Mara

Vipimo vya Valve ya Lango Maswali Yanayoulizwa Mara kwa Mara

What is the main difference between Class 150 and Class 300?

Class 300 features significantly larger flange diameters (D), thicker walls, and heavier construction. Class 300 can operate at roughly 3× the pressure of Class 150. Review the dimension tables to see the specific size differences—they are dramatic.

Can I install a Class 300 valve in a Class 150 system?

Physically yes, but it's wasteful. While a Class 300 will install in a Class 150 system, you'll incur unnecessary cost and weight. All system components should use consistent pressure ratings for safety and economy.

Why is face-to-face length (L) critical in CAD design?

Face-to-face length determines the axial space occupied by the valve in the piping. Accurate L values are essential in 3D pipe routing and interference checking to ensure the valve clears adjacent equipment, supports, and structures.

Must Class 600 and Class 900 use gear drive?

Strongly recommended. While small Class 600 valves might theoretically use handwheel operation, the required torque becomes excessive. Class 900 must be gear-driven. Handwheel operation risks equipment damage and personnel injury—always comply with pressure equipment safety standards.

What does "/" mean in the dimension tables?

"/" indicates data not applicable or requiring special confirmation. Weight data, for example, varies by material, gate type, and special configurations. Always request manufacturer weight certificates for critical applications.

Where can I get Class 1500 / 2500 dimension data?

Xintai Valves manufactures API 600 gate valves in all classes from 150 to 2500. For Class 1500/2500 dimension tables, technical datasheets, and CAD drawings, contact our engineering team na maelezo yako ya programu.
