る。 However, with the development of consumer-oriented industries in recent years,
Live fish are transported along with seawater and lake water. In such a case, the conventionally known butterfly valve with a circular valve opening can be used to change the shape or swimming state of a fish such as a vertically elongated fish belonging to the family Arididae or an elongated fish, or a fish having a horizontally elongated form such as flounder or flounder. Therefore, there is a risk that the fish will collide with the valve body and damage its fins and tail.

Sealing linings 3 and 4 made of rubber-like elastic material
When the valve is closed, the sealing linings 3 and 4 are brought into close contact with each other to form a seal. Reference numeral 5 denotes a valve rod extending in the diametrical direction, which rotatably supports the valve body 2 in the main body 1, and has one end protruding outside the main body 1 to be connected to a desired driving means.

成樹脂等の非金属材料で形成される。 The main body 1 and the valve body 2 are formed into an elliptical or oval shape in which the diameter in the valve axis direction is larger than the diameter in the direction orthogonal to the valve axis. In reality, it is difficult to precisely form the main body and valve body into such an oval or oval shape by machining, but in this invention, the main body 1 and the valve body 2 are provided with a sealing lining 3, 4, and this lining was vulcanized and molded using a mold. The linings 3 and 4 are made of a non-metallic material such as synthetic rubber or synthetic resin that has corrosion resistance and chemical resistance depending on the properties of the fluid and usage conditions.

る。 In the illustrated embodiment, it is formed into an oval shape with arcs having a radius equal to 1/2 of the minor axis at both ends of the major axis, and the valve stem 5 passes through the center in the major axis direction. The valve stem 5 is fixed to the valve body 2 by a taper pin 6,
After the valve body and valve stem are assembled, the head of the taper pin 6 is covered with a covering material 7 such as rubber or Epoquin resin, which is the same as the lining material, and the metal portion is hidden.

魚のひれや尾を損傷するおそれがなくなる。 As a result, a vertically or horizontally long valve opening adapted to the shape or swimming state of the live fish is formed, and there is no problem for the live fish to pass through the valve opening. And since the entire outer peripheral surface is covered with a rubber-like elastic sealant, there is no risk of damaging the fins or tails of live fish.
