金、１３はばね座金、１８はガスケットを示す。In addition, in the figure, 11 is a limit bolt, 12 is a ground stopper, 13 is a spring washer, and 18 is a gasket.
上述のように、本考案によれば、球形弁本体１内に形成
された弁室内に球形弁子３を配置し、この球形弁子３を
回転するために３の上部に弁棒４をとりつけ、この弁棒
４の周りにグランド５およびグランドパツキン１６より
戒る密封装置を設けて、弁棒４と弁本体１の内面との間
にグランド廻りの１次的密封を行なう。As described above, according to the present invention, the spherical valve element 3 is arranged in the valve chamber formed in the spherical valve body 1, and the valve stem 4 is attached to the upper part of the spherical valve element 3 in order to rotate the spherical valve element 3. A sealing device including a gland 5 and a gland packing 16 is provided around the valve stem 4 to provide a primary seal around the gland between the valve stem 4 and the inner surface of the valve body 1.
また、球形弁本体１の上部に嵌合するキャップ６を水平
面内で回転自在に設け、該キャップ６の頂壁と該弁棒４
との間に植込キー１４を設けて、これにより該キャップ
６の頂壁の下面と該弁棒４とを回転力伝導係合状態に連
結し、且つこのキャップ６の周壁の内面と弁本体１の外
周面との間にＯリング１９より戒る密封装置に設けて、
キャップ６と弁本体１との間に２次的密封を行なう。Further, a cap 6 that fits on the upper part of the spherical valve body 1 is rotatably provided in a horizontal plane, and the top wall of the cap 6 and the valve stem 4 are connected to each other.
An implantable key 14 is provided between the cap 6 and the valve stem 4, thereby connecting the lower surface of the top wall of the cap 6 and the valve stem 4 in a state of rotational force transmission engagement, and connecting the inner surface of the circumferential wall of the cap 6 with the valve body. Provided in a sealing device between the outer peripheral surface of 1 and the O-ring 19,
A secondary seal is provided between the cap 6 and the valve body 1.
さらに、該キャップ６の頂壁の上面中央に角部６′を形
成し、該角部６′は球形弁の口径の大小にかかわらず、
外形寸法を同一に構成して、この角部に係合する共通の
操作具により弁の開閉操作を行なうようになっている。Furthermore, a corner 6' is formed at the center of the upper surface of the top wall of the cap 6, and the corner 6' is formed in the center of the upper surface of the top wall of the cap 6.
The external dimensions are the same, and the valves are opened and closed using a common operating tool that engages with this corner.
本考案による球形弁は、このように構成されているので
、狭隘な陥穴内に設置された各種口径の球形弁を地上に
おいて自由な足場において、共通の操作具によって開閉
操作することができる。Since the spherical valve according to the present invention is constructed in this way, spherical valves of various diameters installed in a narrow sinkhole can be opened and closed using a common operating tool from a free platform on the ground.
然して、本考案によれば、弁棒と本体の間の１次的密封
およびキャップと本体との間の２次的密封によって２重
密封を行なうので、特にガス体、危険性流体における漏
洩防止に有効で、且つこのキャップ自体に操作具と係合
する角部を形威しであるので、前記のように狭隘な陥穴
内に設置された球形弁の場合、キャップ付の状態のまま
地上から操作具によって開閉操作できる。However, according to the present invention, double sealing is achieved by the primary sealing between the valve stem and the main body and the secondary sealing between the cap and the main body, which is particularly effective in preventing leakage of gases and hazardous fluids. This is effective, and since the cap itself has a corner part that engages with the operating tool, in the case of a spherical valve installed in a narrow sinkhole as described above, it can be operated from the ground with the cap attached. Can be opened and closed using tools.
然して、弁本体の上部はキャップによって完全に覆われ
ているので、弁棒と弁本体の間に土その他の異物が入り
込むことは防止される。However, since the upper part of the valve body is completely covered by the cap, dirt and other foreign matter are prevented from entering between the valve stem and the valve body.
