供热专用全焊接球阀

产品特点

1、高能阀门集团有限公司的全焊接球阀是采用国际先进技术，自主研制的新产品。

2、全焊接球阀在欧美国家各领域所使用非常广泛。其优越的品质和高性能的稳定性是普通铸钢球阀所无法达到的，其使用寿命远远大于铸 钢球阀、全焊接球阀广泛应用于城市燃气、城市供热、石油化工、造船、钢铁、调压站、发电厂等各类管道设备上。

3、全焊接球阀能长期可靠运行使用，不需要维护，安装简便，特别是DN300以下，使阀门的安装变得更为便捷，不仅降低了工程施工的成 本，也节省了时间。

1、Fully welded ball valve of gaoneng valve group co., ltd. is  using oversea advance production technology, the new product  is design and manufacture by autonomous. 

2、The fully welded ball valve is wildly used in every fiekis in  European and America countries. Its excellent qualility and the stability of high-performance are unreachable for ordinary cast steel ball valves. and its working life is much longer than cast steel ball valves. Full welded ball valve are widely used in city gas. city heating, petrochemical industry, shipbuilding, steel offtake stations,power plants, and other pipelineequipments.

3、Fully welded ball valve can be used long-term with reliable operation, needn't maintain and easy to install (specifically under DN300). So the installation of the valve becomes more convenient,it's not only reduces the cost of construction, but also saves a lot of time.

阀体水压检测Shell Hydrostatic Test

(2)密封水压检测Seal Hydrostatic Test

密封水压检测要超过阀门使用压力等级1.1倍的水压力，在不同的型号都有规定的不同的时间内，加压后密封是否有外漏。

The pressure should be more 1.1 times than working pressure by seal hydrastatic test

(2)气压密封泄漏检测Seal Air Test

气压密封泄漏检测是以80psig (6kgf/cm2)惰性气体或空气充分加压后关闭阀门，在阀门一侧检查阀门是否泄漏。

Seal air leakage test is based on 80PSIG (6kgf/cm2) nin-actiue gas of full lilled with air, after clase the valve, then check it is leakage or not by one side of the valve
