Description
Technical field
The utility model relates to a kind of valve technology field, is specifically related to a kind of fixing ball valve.
Background technique
Fixing ball valve be a kind of use laborsaving, the valve products of good sealing effect, and closed circuit device made by the pipeline being widely used in water, rock gas, coal gas, liquefied petroleum gas and oil refining, airport, chemical industry, Oil & Gas Storage etc.
The valve seat of traditional fixing ball valve and ball seal structure mainly adopt the Hermetical connecting structure being fixedly connected on seal ring on valve seat and spheroid and offseting, and this Placement sealing effect is very poor, easily causes liquid or Leakage Gas.And the spheroid of fixing ball valve is solid construction, which not only adds overall weight, and cost of production is also high.
Summary of the invention
The purpose of this utility model is: provide a kind of good sealing effect, ball design is become hollow-core construction, reduces overall weight, and reduces the fixing ball valve of cost of production.
In order to achieve the above object, the technical solution of the utility model is: a kind of fixing ball valve, comprise valve body, with the spheroid of opening, valve rod, valve seat and end cap, end cap is fixedly connected with valve body, and form valve pocket, spheroid is positioned at valve pocket, one end of valve rod is stretched in valve pocket, and be fixedly connected with spheroid, valve seat has two, and lay respectively at the both sides of spheroid, and be fixedly connected with end cap with valve body respectively, valve body and end cap are respectively equipped with first passage and second channel, also comprise two bracing rings, two bracing rings are set on respective valve seat, and be provided with spring between bracing ring and valve seat, bracing ring is provided with at least one rigid seal ring and at least one soft seal ring, rigid seal ring and soft seal ring all offset with spheroid periphery, described spheroid comprises ball core, two axle beds and be fixedly connected on the spherical housing of ball core both ends of the surface respectively, one end of axle bed is fixedly connected with shell, the other end is fixedly connected with ball core, valve rod and axle bed load.
In technique scheme, the rigid seal ring on described bracing ring and soft seal ring offset.
In technique scheme, described end cap and valve body are equipped with spring receiving bore, and spring is positioned at spring receiving bore, and stretches out spring receiving bore and bracing ring offsets.
The good effect that the utility model has is: the method that the utility model combines owing to seal ring to be adopted rigid seal ring and soft seal ring, and when spheroid rocks, spring can ensure that rigid seal ring on bracing ring and soft seal ring are tight against spheroid all the time, improves sealability.And described spheroid comprises ball core and spherical housing is formed, and compared with prior art, ball design is become hollow-core construction, while not reducing sphere structure intensity, not only reduce overall weight, and also reduce cost of production.
