Abstract
A valve (10) in accordance with an embodiment of the present invention includes a body (1) having a space in which a stem (3) and a ball (4) are housed, wherein an inner lid body (60) fixing the ball (4) in the space liquid-tightly partitions the space into a part in which the stem (3) is housed and a part in which the ball (4) is housed.
Claims11
A valve comprising:
- a body constituting a flow path of a fluid, the body having a plurality of first openings for distributing the fluid and a second opening that opens in a direction intersecting with a direction in which the plurality of first openings face and that allows a valve element to pass therethrough;
- the valve element being placed in the body via the second opening and allowing the flow path of the fluid to be opened and closed;
- a stem being connected to the valve element and extending outside the second opening;
- a bonnet sealing the second opening in such a manner that the stem is operable;
- and
- an inner lid body proximal the valve element and partitioning a space in the body into a space on a side of the bonnet and a space on a side of the valve element, in such a manner that the stem is operable and in a liquid-tight or air-tight manner,
- the inner lid body having a first plate and a second plate in this order from a side closer to the valve element,
- the second plate being fixed to the body by a fixing means, and
- the first plate being not fixed to the body and being subjected to restriction in movement to the space on the side of the bonnet by the second plate being fixed to the body.
