Compress the sealing clamping ring of valve seat, it is characterised in that the sealing clamping ring sets a pair of overhanging cylinder in its side along diametrically opposite
Pin is correspondingly provided with the sleeping overhanging straight pin and recessed with the pin annular of its clearance fit of filling on valve body eccentric side latus rectum face
Slot slits on pin annular groove cell wall corresponding with overhanging straight pin equipped with the insertion for extending to valve body bias side end face
Mouthful；The sealing clamping ring is connected by the overhanging straight pin being fitted by the insertion gap in pin annular groove with valve body.
The material of the valve plate and sealing clamping ring is stainless steel, and valve seat material is plastics.
The plastics include polytetrafluoroethylene (PTFE), Kynoar, Meltability polytetrafluorethyletubular or polyether-ether-ketone resin.
The beneficial effects of the utility model are：The soft seal double eccentric butterfly valve that a kind of assembling structure is provided to simplify, with showing
There is technology to compare, (1) valve body need not process multiple threaded holes, and sealing clamping ring need not process multiple counterbores, and processing is time saving, saves
Power, simplifying technique reduces cost.(2) when assembling valve, sealing clamping ring side sets two pin holes, sealing clamping ring along diametrically opposite
Being connected with valve body only needs two straight pins, reduces fastener quantity, operation is time saving and energy saving, efficient at low cost.(3) plastics
After valve seat generates abrasion, disassembling, assembling and replacing is time saving, laborsaving.
