The first filter 33 is installed inside the lower body 30 to filter foreign matter in the fluid to prevent foreign matter from being caught between the buoy and the packing. A guide support plate 39 is installed at the bottom of the first filter 33 to be in contact with the bottom of the first filter 33 to support the components inside the body as a whole, and at the same time, a fluid flow control tube 31 is installed at the bottom of the guide support plate 39. I support it. The fluid flow control tube 31 extends downward from the guide support plate 39 to allow air to flow into the body.

In addition, a packing support plate 11 is installed on an inner circumferential wall of the upper body 10, and a packing 13 in surface contact with the floating means 40 is coupled to the packing support plate 11.

An upper flange 15 is integrally formed on the lower outer circumferential surface of the upper body 10, and a plurality of coupling holes 17 are formed in the upper flange 15 along the circumferential direction, and the lower body 30 is formed.
