Abstract
A liquid surface height inside a tank is allowed to be confirmed while blow-back of a liquid is reduced. A strainer body having a substantially bottomed tubular shape has a substantially D shape when viewed in a longitudinal direction. A bottom surface of the strainer body has a shape in which a part of a conical shape is cut away, and a top of the substantially conical shape overlaps with a notched portion notched to form the substantially D shape. The bottom surface protrudes toward an opening of the strainer body. A rod is provided adjacent to the notched portion of the strainer body, and a float is provided on a lower end of the rod.
Claims6
A strainer provided inside an injection port for injection of a liquid into a tank body, the strainer, comprising:
- a strainer body having a bottomed tubular shape that includes a side surface and a bottom surface, the side surface including a net-like body through which the liquid is passable, the net-like body being absent on the bottom surface, the liquid being not passable through the bottom surface;
- a rod provided adjacent to the strainer body, the rod being provided along a first direction as a longitudinal direction of the strainer body;
- a guide portion that regulates a moving direction of the rod such that the rod moves along the first direction;
- and
- a float disposed on a distal end on the bottom surface side of the rod, wherein
- the side surface has a substantially D shape when viewed in the first direction, the side surface includes a notched portion and a curved surface portion other than the notched portion, and the notched portion is cut away so as to form the substantially D shape,
- the rod is provided at a position overlapping with a circle as a n extension of the curved surface portion and a position adjacent to the notched portion when viewed in the first direction, and
- the bottom surface has a shape in which a part of a conical shape is cut away and protrudes toward an opening of the strainer body, and a top of the conical shape overlaps with the notched portion,
- wherein
- the guide portions are two rod shaped bodies extending from the bottom surface so as to protrude in the first direction,
- the float has a tubular shape,
- both sides of the float are sandwiched between the two rod shaped bodies, and
- a position of the float overlaps with a position of the bottom surface when viewed in the first direction.
A strainer provided inside an injection port for injection of a liquid into a tank body, the strainer, comprising:
- a strainer body having a bottomed tubular shape that includes a side surface and a bottom surface, the side surface including a net-like body through which the liquid is passable, the net-like body being absent on the bottom surface, the liquid being not passable through the bottom surface;
- a rod provided adjacent to the strainer body, the rod being provided along a first direction as a longitudinal direction of the strainer body;
- a guide portion that regulates a moving direction of the rod such that the rod moves along the first direction;
- and
- a float disposed on a distal end on the bottom surface side of the rod, wherein
- the side surface has a substantially D shape when viewed in the first direction, the side surface includes a notched portion and a curved surface portion other than the notched portion, and the notched portion is cut away so as to form the substantially D shape,
- the rod is provided at a position overlapping with a circle as an extension of the curved surface portion and a position adjacent to the notched portion when viewed in the first direction, and
- the bottom surface has a shape in which a part of a conical shape is cut awa y a nd protrudes toward an opening of the strainer body, and a top of the conical shape overlaps with the notched portion,
- wherein the net-like body is provided on the notched portion in a part above the bottom surface.

- a guide portion that regulates a moving direction of the rod such that the rod moves along the first direction;
- and
- a float disposed on a distal end on the bottom surface side of the rod, wherein
- the side surface has a substantially D shape when viewed in the first direction, the side surface includes a notched portion and a curved surface portion other than the notched portion, and the notched portion is cut away so as to form the substantially D shape,
- the rod is provided at a position overlapping with a circle as an extension of the curved surface portion and a position adjacent to the notched portion when viewed in the first direction, and
- the bottom surface has a shape in which a part of a conical shape is cut away and protrudes toward an opening of the strainer body, and a top of the conical shape overlaps with the notched portion,
- wherein an angle formed by a generatrix of the bottom surface and a horizontal plane is approximately 60 degrees.
