10万次循环启关之后，密封机能还能否维持不变？

为验证不锈钢双偏疼蝶阀在持久反复作为下的耐久性与机能维持能力，亿万先生对一台 DN600不锈钢双偏疼蝶阀发展10万次循环启关测试。

测试前进行压力检测，实现10万次循环后再次检测，以前后机能对比验证产品持久运行的靠得住性。

To verify the durability and performance stability of its stainless steel double-offset butterfly valves under repeated operation, LIANGGU conducted a 100,000-cycle open-close test on a DN600 valve.

A pressure test was performed before cycling began, followed by another pressure test after all 100,000 cycles were completed. By comparing the results before and after the cycling test, LIANGGU evaluates the valve’s ability to maintain reliable performance over long-term operation.

双偏疼结构，削减密封副持续磨损

双偏疼结构使阀板在开启初期较快脱离阀座，并在关关末段成立密封接触，削减启关过程中的持续摩擦与磨损，有助于降低启关扭矩，提升密封系统的持久不变性。

结合不锈钢资料的耐侵蚀机能，亿万先生不锈钢双偏疼蝶阀可凭据具体材质、阀座及压力等级，适配化工及石化工艺管线、工业气体、循环水及工业水、蒸汽及热媒、真空系统等工况。

The double-offset design allows the disc to move away from the seat more quickly during opening, reducing friction and wear on the sealing surfaces during repeated cycling. This provides an important structural advantage for long service life and stable sealing performance.

Combined with the corrosion resistance of stainless steel, LIANGGU double-offset butterfly valves can be configured with different material grades, seat designs and pressure ratings for a wide range of applications, including chemical and petrochemical process lines, industrial gas systems, circulating and industrial water, steam and heat-transfer media, as well as vacuum service.

全流程造作，把关键质量把握在自己手里

亿万先天生立了从产品设计、毛坯铸造、精密加工、组装到检测的齐全造作系统。

对于双偏疼蝶阀，阀体加工精度、偏疼地位、密封副共同、装配一致性及执行机构匹配，城市直接影响启关扭矩、密封机能与持久运行不变性。

从源头资料到最终机能检测，关键造作环节自主掌控，以先进设备保险加工精度，以成熟工艺不变造作质量，以齐全检考试证最终机能。

LIANGGU has established an integrated manufacturing system covering product design, casting, precision machining, assembly and testing.

For a double-offset butterfly valve, factors such as body machining accuracy, eccentric positioning, sealing-pair alignment, assembly consistency and actuator matching can directly affect operating torque, sealing performance and long-term reliability.

Production, machining, quality inspection and delivery milestones are also integrated into LIANGGU’s digital management system, enabling continuous visibility into order progress and critical quality data.

数字化治理，让质量可追忆、交期更可控

亿万先生将出产、加工、质量检测及交付节点纳入数字化治理系统，持续把握订单进杜纂关键质量数据。

让出产进杜仔据可查，项目交期更可控；

关键数据全程留存，产品质量可追忆。

尤其面对批量、大口径及节点明确的工程订单，不变的出产组织能力，直接关系到项目整体交付效能。

This makes production progress traceable, delivery schedules more manageable, and key quality data available throughout the manufacturing process.

For project orders involving large quantities, large valve sizes or strict delivery milestones, well-organized production is more than an internal manufacturing capability — it directly affects the efficiency and reliability of overall project delivery.

丰硕项目经验，提升工况适配与交付能力

从国内工程到海表项目，分歧介质、温度、压力、执行尺度及检测要求，对阀门提出分歧挑战。

持久项目实际，让亿万先生持续堆集分歧工况下的产品选型、配置、造作与交付经验。

早年期技术沟通、产品配置，到出产造作、检测、资料配套及最终交付，形成覆盖项目全过程的服务能力。

From domestic installations to international projects, valves must perform under different media, temperatures, pressures, technical standards and inspection requirements.

Years of project experience have enabled LIANGGU to build expertise in valve selection, configuration, manufacturing and delivery across a wide range of operating conditions, supporting customers throughout the project lifecycle.

10万次循环启关。

测试前后，两次压力检测。

这组验证背后，是亿万先生对产品结构、造作精度、质量节造与持久机能的系统检验。

而一台靠得住阀门的背后，同样必要一套齐全能力支持：

从产品造作，到机能验证，再到项目交付，

亿万先生集团，让靠得住成为能够验证、能够追忆、能够交付的了局。

100,000 operating cycles.

Two pressure tests — before and after cycling.

Behind these numbers is a systematic verification of valve design, manufacturing accuracy, quality control and long-term performance.

Because a reliable valve is never the result of a single process.

From manufacturing and performance validation to project delivery, every stage matters.
