主要結構特點及用途：
Chief strucure features and usages：

The chamber of packing of the valve's bonnet is of a water-sealed structure,which,when the water of 0.6-1MPa pressure goes into the mouthpiec,can make the system isolated from air to ensure the system with a good leak proofness
Model S/Z series use dual-gate dual-direction elastic sealings.being flesible and fast to open and close,reliable sesling
Simple,compact and reaso able structur,easy to overhaul and long duration
When to be used as the open&close device on pipelines,it must be in fully-opened or fully-closed state and unallowed to be used for flow adjustment
Two ways of connection:by flange and welding,two driving ways:manually and electrically
Suitable to act as the open & close device for the pipelines with the working medium of water,steam,oil goods and non-corrosive gas,especially for the vacuum condensation system of the steam tufbine in steam power palnts.
