阀装置
摘要：
本发明提供了一种用于气体罐(2)的阀装置(1)，该阀装置包括本体(4)和设置在注入通道(13)中以使气体注入气体罐(2)的止回阀(16)。止回阀(16)包括阀座(33)、壳体(34)和阀元件(35)，壳体固定在注入通道(13)中，同时在注入通道(13)的内周表面(31a)与壳体(34)之间设置有空间以使气体能够流过该空间，阀元件容纳在壳体(34)中。壳体(34)包括筒部(41)并且构造成使得筒部(41)的设置在与阀座(33)相反侧的底部(42)限定阀元件(35)能够轴向移动的范围。阀元件(35)包括头部(51)和滑动部(53)，头部可以将阀座(33)的阀孔(37)堵住，滑动部形成为能够相对于筒部(41)轴向移动。
摘要（英）：

The present invention provides a valve device (1) for a gas tank (2). The valve device includes a body (4) and a check valve (16) arranged in an injection passage (13) to inject gas into the gas tank(2). The check valve (16) includes a valve seat (33), a case (34) fixed in the injection passage (13) while a space is arranged between an inner peripheral surface (31a) of the injection passage (13)and the case (34) to enable gas to flow through the space, and a valve element (35) accommodated in the case (34). The case (34) includes a cylindrical portion (41), and is configured such that the bottom (42) of the cylindrical portion (41), arranged at an opposite side to the valve seat (33), defines a range where the valve element (35) is axially movable. The valve element (35) includes a headportion (51) that can block a valve hole (37) of the valve seat (33), and a sliding portion (53) formed to be axially movable with respect to the cylindrical portion (41).
