Gate valve domain technology field.
Background technology:
The fused salt that existing market provides valve uses shut-off valve valve class more, but the circulation of shut-off valve internal structure complications hinders
Power is big, and entire pipeline flow of media can be made to generate the larger pressure loss.Therefore new construction begins to use gate valve in recent years
As the valve of control piper, current fused salt there is also some problems in use with gate valve, such as (1) fused salt at this stage
In the valve body of gate valve flange sealing element mostly use conventional seals shim form (2) valve stem seal realized only with mica filler it is close
The center line of valve seat groove bottom and lumen on envelope (3) gate valve body has 5 degree of inclination angle, and channel is caused to generate corner angle.(4) in
Chamber is without relief hole, and problem above can cause the enclosed watch area of generation (1) conventional seals gasket of following situations big, material rebounds
Property it is poor, be easily used to cause lumen leakage and excessive (2) the mica filler sealing of middle flange stress in high temperature and temperature alternating
Property and surface smoothness be not so good as graphite packing, the simple valve seat being easy on leakage (3) gate valve body using mica sealing is pacified
Tankage has 5 degree of inclination angle, and after valve seat installation, can generate some corner angle in the channel influences flow of media.(4) fused salt operating mode
Temperature alternating is big, is deposited in the fused salt of valve body middle chamber and can be converted between mushy stage and liquid, lumen can lead to lumen without hole is let out
Pressure causes dangerous situation, the keying that lumen can also influence valve without relief hole dynamic beyond safety value.
Pneumatic bellows fused salt gate valve, is mainly used in new cleaning fuel --- each system pipes of fused salt solar power generation
