Description
【発明の詳細な説明】 （産業上の利用分野） この発明はガスコックに関する。[Detailed description of the invention] (Industrial application field) This invention relates to a gas cock.
（従来の技術）
大型のガスコックでは、鉄製のガスコック本体に収納空
間が形成されていて、この収納空間に真鍮製の栓が回動
可能に収納されている。上記収納空間の内周面と栓の外
周面とは、下方に向かって小径のテーパをなしており、
互いに接している。(Prior Art) In a large gas cock, a storage space is formed in the iron gas cock body, and a brass stopper is rotatably stored in this storage space. The inner circumferential surface of the storage space and the outer circumferential surface of the stopper taper downward to a small diameter.
are in contact with each other.
従来では、第２０図〜第２２図に示すようにして栓１０
０が構成されていた。すなわち、栓１００は流通路１０
６を有しており、この流通路１０６がガスコック本体の
流入口および流出口と合致した時にがスの流通を許容し
、合致しない時にはガスを遮断するようになっている。Conventionally, the stopper 10 is installed as shown in FIGS. 20 to 22.
0 was configured. That is, the plug 100 is connected to the flow path 10
6, and when the flow passage 106 matches the inlet and outlet of the gas cock body, the gas is allowed to flow, and when they do not match, the gas is shut off.
ところで、上記ガス流通を円滑に行ない圧力損失を少な
くするには、流通路１０６の断面形状をガス流通方向に
沿ってほぼ等しくする必要がある。By the way, in order to perform the gas flow smoothly and reduce pressure loss, it is necessary to make the cross-sectional shape of the flow passage 106 substantially equal along the gas flow direction.
このため、上記収納空間の内周面に接する栓１００の外
周面１００ａと、流通路１０６を形成する面１０６ａと
の開の肉厚を、厚くせざるを得なかった。Therefore, the thickness of the opening between the outer circumferential surface 100a of the stopper 100 that contacts the inner circumferential surface of the storage space and the surface 106a forming the flow path 106 has to be increased.
（発明が解決しようとする問題点）
上記ガスコックでは、熱サイクルにより栓１００の初動
トルク（回動し始める時のトルク）が増大して開閉操作
不能に至ることがあった。これは、主にガスコック本体
と栓１００の熱膨張率の違いおよび栓１００を付勢する
スプリング力に起因している。詳述すると、寒い時期に
栓１００の径がガスコック本体の収納空間の径より小さ
くなり、栓１００がスプリング力により若干量下降する
。(Problems to be Solved by the Invention) In the above-mentioned gas cock, the initial torque (torque when it starts to rotate) of the stopper 100 increases due to the thermal cycle, and the opening/closing operation may become impossible. This is mainly due to the difference in thermal expansion coefficient between the gas cock body and the stopper 100 and the spring force that biases the stopper 100. To be more specific, during the cold season, the diameter of the stopper 100 becomes smaller than the diameter of the storage space of the gas cock body, and the stopper 100 is lowered by a certain amount due to the spring force.
次の暑い時期に栓１００がガスコック本体より大きく膨
張しようとする。この結果、栓１００はガスコック本体
により締め付けられることになり、栓１００の外周面１
００ａと収納空間の内周面との間の摩擦力が大となり、
栓１００の初動トルクが増大する。従来のガスコックで
は、上述したように栓１００の肉厚が厚いため、上記栓
１００の締め付は力を逃がして緩和することができず、
初動トルクが著しく増大して回動不能に至ることがあっ
た。During the next hot season, the stopper 100 will try to expand more than the gas cock itself. As a result, the plug 100 is tightened by the gas cock body, and the outer peripheral surface of the plug 100
The frictional force between 00a and the inner peripheral surface of the storage space increases,
The initial torque of the stopper 100 increases. In the conventional gas cock, since the plug 100 has a thick wall thickness as described above, the tightening of the plug 100 cannot be relaxed by releasing force.
In some cases, the initial torque increased significantly, resulting in the inability to rotate.
（問題点を解決するための手段）
この発明は上記問題点を解消するためになされたもので
