Pahnihnaah chuan, performance testing content-ah hian...valve a ni
1. A lan dan leh logo endik
(1) Inspection content: valve lan danah chhiatna a awm leh awm loh, chu chu crack, bubble, dents, etc. Logo, nameplate leh finish te hian a mamawh a tlin em tih enfiah rawh. (2) Standard: International standard-ah hian API598, ASMEB16.34, ISO 5208, etc. te a tel a; Chinese standard-ah chuan GB/T 12224 (steel valve-a thil tul tlangpui), GB/T 12237 (petroleum, petrochemical leh a kaihhnawih industry-a steel ball valve), etc. (3) Test dan: mit hmuha enfiah leh kut hmanga enfiahna hmangin valve chung lamah chhiatna langsar tak tak a awm leh awm loh hriat theih a ni a, hriat theihna leh nameplate information chu a dik em tih enfiah a ni.
2. Dimensional tehna
(1) Inspection content: Valve-a key dimension te, connection port, valve body sei zawng, valve stem diameter, etc. te chu design drawing leh standard-a thil tulte a tlin leh tlin loh tehna tur a ni. (2) Standard: International standard-ah hian ASMEB16.10, ASME B16.5, ISO 5752, etc. te a tel a; Chinese standard-ah chuan GB/T 12221 (valve structure sei zawng), GB/T 9112 (flange connection size), etc. (3) Test dan: Caliper, micrometer leh tehna hmanrua dangte hmangin valve key dimensions te chu design mamawh a tlin leh tlin loh tehna atan hman a ni.
3. Sealing hnathawh dan test
(1) Static pressure test: valve-ah hydrostatic pressure emaw static pressure emaw dah la, hun engemaw chen i enkawl hnuah leakage chu enfiah rawh. (2) Low-pressure air tightness test: Valve khar a nih chuan valve chhungah low-pressure gas hnawih a, a leakage enfiah a ni. (3) Housing strength test: a housing strength leh pressure resistance test nan valve-ah hian working pressure aia sang hydrostatic pressure dah la. (4) Stem Strength Test: Stem hnathawh laiin torque emaw tensile force emaw a tawn chu a him tawk em tih enfiah thin ang che.
4. Operational performance test neih a ni ang
(1) Opening and closing torque leh speed test: valve hawn leh khar torque, hawn leh khar speed leh operation feel te test la, a thawk tha thei ang bera leh torque range mumal chhungah a thawk thei ang. (2) Flow characteristics test: valve-in a flow characteristics chu opening hrang hrangah test a, fluid a tihregulate theih dan tehna tur a ni.
5. Corrosion laka invenna test
(1) Evaluation content: valve material chu working medium-ah a corrosion resistance endik. (2) Standards: International standard-ah chuan ISO 9227 (salt spray test), ASTM G85, etc. te a tel a (3) Test dan: Valve hi salt spray test chamber-ah dah a ni a, chu chuan corrosive environment simulate a, corrosive condition hnuaia material durability test a ni.
6. Durability leh rintlakna test
(1) Repeated opening and closing cycle test: Valve-ah hian hun rei tak hmanna atana a chhe thei lo leh a rintlakzia tehna atan opening leh closing cycle repeated an nei thin. (2) Temperature stability test: temperature condition hrang hrang hnuaiah valve performance stability test la, temperature sang tak awmna hmuna a hnathawh dan pangngai a nih leh nih loh enfiah thin ang che. (3) Vibration leh shock test: Valve chu shaking table emaw impact table emaw-ah dah la, hnathawhna hmuna vibration leh shock awm dan simulate a, valve stability leh rintlak loh test nan.
7. Leak hmuhchhuah
(1) Internal leak detection: a chhunga sealing performance testvalve a nikhar state-ah a awm. (2) Pawn lam atanga leakage hriat theihna: pawn lam tightness enfiah rawhvalve a nimedium leakage a awm loh nan hman mek a ni.
