A kind of stainless steel ball valve No leakage formula sphere structureTechnical field:
This utility model relates to stainless steel ball valve, particularly relates to a kind of stainless steel ball valve No leakage formula sphere structure.
Background technology:
Stainless steel ball valve has only to the operation with 90-degree rotation and only small rotating torque just can be closed tight.The body cavity of complete equality is the runner that medium provides that resistance is only small, straight-through.
Ball valve be mainly characterized by compact conformation own, it is easy to Operation and maintenance, stainless steel ball valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
The spheroid of stainless steel ball valve is after being installed in valve body valve pocket in the market, in work process, the sealing between spheroid and valve pocket is poor, liquid or the gas of crossing stream in ball valve can leak in the gap between left valve barrel and right valve barrel and in valve rod installing hole, needing to change in time ball valve, cost is high.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of stainless steel ball valve No leakage formula sphere structure, it is ensured that ball valve sealing between spheroid and valve body in the course of the work, it is ensured that without leakage phenomenon.
The technical solution of the utility model is as follows:
Stainless steel ball valve No leakage formula sphere structure, including spherosome, it is characterized in that, described spherosome is provided with and is diametrically provided with fluid penetrating via, penetrating via vertical direction spherosome top is provided with valve rod installing hole, being respectively equipped with integrated upper seal disc, lower seal dish on the spherosome outer wall of described penetrating via upper and lower, upper seal disc, lower seal dish match with the sealing mounting groove on stainless steel ball valve body.
Described stainless steel ball valve No leakage formula sphere structure, it is characterised in that being respectively equipped with upper seal bore, lower seal cylinder on described upper seal disc, lower seal dish opposite face, upper seal bore, lower seal barrel cover are in the sealing mounting groove of stainless steel ball valve.
The utility model has the advantages that:
This utility model topology layout is reasonable, by designing seal disc on spheroid, constitutes seal combination structure between seal disc and valve body, it is ensured that ball valve sealing between spheroid and valve body in the course of the work, it is ensured that without leakage phenomenon.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Referring to accompanying drawing:
Stainless steel ball valve No leakage formula sphere structure, including spherosome 1, spherosome 1 is provided with and is diametrically provided with fluid penetrating via 2, penetrating via 2 vertical direction spherosome top is provided with valve rod installing hole 3, being respectively equipped with integrated upper seal disc 4, lower seal dish 5 on the spherosome outer wall of penetrating via 2 upper and lower, upper seal disc 5, lower seal dish 6 match with the sealing mounting groove on stainless steel ball valve body.
Being respectively equipped with upper seal bore 7, lower seal cylinder 8 on upper seal disc 4, lower seal dish 5 opposite face, upper seal bore 7, lower seal barrel cover 8 are in the sealing mounting groove of stainless steel ball valve.
This utility model by installing the upper seal disc 4, the lower seal dish 5 that match with valve seal mounting groove additional on rustless steel spheroid, go up simultaneously and seal disc 4, lower seal dish 5 are provided with upper seal bore 7, lower seal cylinder 8, it is ensured that the tight property of sealing between spherosome 1 and valve pocket.
