Adopt technique scheme, coated anticorrosive coat respectively on inwall by the medium inlet passage at valve body, medium flow pass and spheroid, make medium inlet passage, medium flow pass and the spheroid of valve body can avoid having the erosion of Korrosionsmedium, thereby extended the working life of valve body and spheroid; The setting that valve seat is set to spring between hard sealing block and valve seat and valve body can make valve seat have all the time the elastic force of conflicting towards spheroid, thereby has improved the sealing between valve seat and spheroid.
The utility model is further set to: anticorrosive coat is anticorrosive PTFE plate, this anticorrosive coat is provided with magnet towards medium inlet passage, the inwall of medium flow pass and the end face of spheroid, between the inwall of medium inlet passage, medium flow pass and spheroid and anticorrosive coat, be provided with its on the magnet inhaled mutually of magnet.
Adopt technique scheme, arrange like this and install and convenient disassembly, in the time that anticorrosive coat need to be changed, can be easily by anticorrosive coat by removing on valve body.
The utility model is further set to: the end face of valve seat and ball seal is provided with plastic sealed layer.
Adopt technique scheme, arrange the sealing between valve seat and spheroid is further protected like this.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the I portion enlarged diagram of Fig. 1;
Fig. 3 is the II portion enlarged diagram of Fig. 1.
Embodiment
