Bar mounting seat is welded on the top of spheroid, and valve rod mounting hole straight down, valve rod installation are offered at the top of valve rod mounting seat
The fixture block that the oriented center of circle protrudes is fixedly installed in hole；The outer sheath of the valve rod mounting seat is provided with a circle sealing ring；The circulation
Pipe level is arranged in spheroid, offers several through holes, through hole and runner pipe corresponding to the both ends of circulation duct on spheroid
Connected in road；One layer of anticorrosive coat is scribbled on the inwall of the circulation duct；It is filled with the out course body of the circulation duct
Thermal insulation layer；One layer of wearing layer is scribbled on the outer surface of the spheroid.
Further：The fixture block is structure as a whole with valve rod mounting seat.
Further：The fixture block is symmetrically arranged with two.
Further：A diameter of 2~4mm of the through hole.
Further：The thermal insulation layer is glass fibre or asbestos.
Further：The wearing layer is high molecular abrasion-proof material.
Compared with prior art, the beneficial effects of the utility model are：The utility model is fixed valve rod by fixture block, is led to
Crossing valve rod rotates valve element spheroid, when not in use can take out valve rod；The through hole of setting enables flow through smooth, and flow velocity is fitted
In, weaken impact when opening valve, ensure the stability that fluid passes through, ensure that equipment is safe to use, on the inwall of circulation duct
Anticorrosive coat is scribbled, circulation duct is protected, avoids flow-induced corrosion circulation duct, extend its service life；Thermal insulation layer avoids inside stream
Body exchanges heat with extraneous, avoids the temperature of fluid from changing, and valve body self-temperature is kept constant, people is used valve safely
Door；Wearing layer reduces the abrasion to spheroid, makes ball valve usage time longer, reduces use cost.
