为使水泥制品、人造大理石和水磨石的性能达到预期要求,都需要经过蒸汽养护。据《中国建材报》报道,北京建设水磨石厂从意大利引进了整条养护生产线,两年后,配套的意大利蒸汽电磁阀损坏了,如果向原厂购进,不仅需要外汇,而且远水救不了近火,于是该厂便选用我厂生产的YJ牌燕汽电磁阀替代,迄今已使用6年之久,仍完好无损,动作正常可靠。该厂技术人员和操作工人一致认为,我厂蒸汽电磁阀的使用寿命已超过意大利蒸汽电磁阀,大大超过了出厂保用两年的期限(见广告)。
In order to achieve the desired performance of cement products, artificial marble and terrazzo, steam curing is required. According to the “China Building Materials News” report, Beijing’s construction of the terrazzo plant introduced the entire maintenance line from Italy. Two years later, the supporting Italian steam solenoid valve was damaged. If it were purchased from the original factory, it would not only need foreign exchange, but it could not be saved near the water. Fire, so the plant will use the YJ brand swallow steam solenoid valve produced by our factory to replace, so far has been used for 6 years, still intact, normal and reliable operation. The plant technicians and operating workers agreed that the service life of the steam solenoid valve of our plant has exceeded the Italian steam solenoid valve, which greatly exceeds the deadline for the factory warranty of two years (see advertisement).
