Description
Technical field
The utility model belongs to valve technology field, particularly a kind of novel ball valve.
Background technique
Existing seal ball-valve does not arrange sink, and what adopt between spheroid and lateral body is rubber seal rings for seal, and this sealing configuration very easily damages rubber seal, causes ball valve maintenance rate high.
Model utility content
In order to overcome the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of novel ball valve.
The technological scheme that the utility model is taked for its technical problem of solution is:
A kind of novel ball valve, comprise middle body, lateral body, spheroid, upper valve rod, Stuffing box and extending bracket, extending bracket and Stuffing box affixed, described extending bracket is provided with radiating fin, Stuffing box one end is located by pin and middle body upper end, the Stuffing box the other end by screw and middle body affixed, support is connected with in extending bracket upper end, Gland is provided with between support and described valve rod, described valve rod runs through described support from top to bottom in turn, Gland, extending bracket and Stuffing box, the lower end of valve rod is by flat key and spheroid clamping, a positioning hole is provided with in the lower end of described spheroid, positioning shaft is provided with in positioning hole, Lower shaft sleeve is provided with between positioning shaft and spheroid, positioning shaft lower end and axle bed integral structure, it is affixed that described axle bed and described middle body pass through screw, graphite pads is provided with between described positioning shaft and middle body.
Elastic sealing structure is provided with between body and described spheroid in described, described elastic sealing structure comprises valve seat and valve seat bearing ring, spring is provided with between lateral body and described valve seat bearing ring, valve base sealing ring is provided with between described valve seat bearing ring and valve seat, between described valve seat and described lateral body, be provided with sealed circular ring, valve seat is connected with ball seal.
The beneficial effects of the utility model: the utility model compared with prior art arranges the gelled extending bracket of tool around the valve rod of filler upper end, valve rod is made to carry out quick heat radiating by extending bracket, guarantee that valve rod can not Yin Gaowen and being out of shape, elastic sealing structure is adopted between spheroid and lateral body, make the mode adopting hard sealing between spheroid and valve seat, the maintenance rate of ball valve is reduced greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
