The working principle of source of the gas ball valve is to make valve unimpeded or inaccessible by rotary valve rod, and the sealing surface of source of the gas ball valve and the sphere closed state of being everlasting is difficult for by medium erosion, in every profession and trade, is widely used.Source of the gas ball valve and stopcock are the valves that belongs to a type together, and the closure member that only has it is a spheroid, and spheroid makes around valve body center line a kind of valve that rotation reaches unlatching, closes.
Source of the gas ball valve is comprised of valve body, valve seat, valve rod, spheroid, pad, filler and handle conventionally.The material of the valve body in source of the gas ball valve is case material (also claiming material of main part), and flap, spheroid, valve seat, valve rod, sealing seat are usually called internals, also has in addition fastening piece, Sealing etc.But source of the gas ball valve of the prior art generally all has the shortcomings such as complex structure, sealing be poor.
Model utility content
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of source of the gas ball valve of simple in structure, good airproof performance is provided.
The utility model is achieved by the following technical solution:
A kind of source of the gas ball valve, comprise left joint, spheroid, valve rod, valve stem seal pad, valve body, joint sealing pad, valve seat, right connector, nut and the combination of double card cover, left joint and right connector are separately positioned on the left and right sides of valve body, in the end face of left joint and right connector, be provided with valve seat, on described valve seat, be provided with spheroid, described valve rod stretches in valve body and is installed in the groove of offering on spheroid; On the surface of contact of described valve rod and valve body, be provided with valve stem seal pad, on the surface of contact of described valve body and left joint and right connector, be provided with joint sealing pad; On right connector, be provided with the combination of double card cover, the combination of described double card cover is outside equipped with nut.
Further setting of the present utility model is, described source of the gas ball valve also comprises Gland and filler, and described filler is arranged in the space between valve rod and valve body, and described Gland is arranged on filler.
Further setting of the present utility model is, on described valve rod, by a spanner is also installed, described spanner is fastened on valve rod by hexagon nut.
Further setting of the present utility model is, is also provided with a locating stud on described spanner.
The valve body material of source of the gas ball valve described in the utility model adopts forged steel, groove on the spheroid that valve rod surrounds with two valve seats is connected, valve body and the locking of two edge connectors reach effect fixing and sealed spheroid, and this product is that screw thread FERRULETYPE connects, simple in structure, favorable sealing property.
