Abstract
The present invention relates to the fluid discharge device of a fluid transfer pipe, and to a technology which alters the sectional area of a discharge hole in proportion to the increase or decrease in fluid discharge flow per unit of time so as to maintain a relatively uniform fluid discharge rate from the discharge hole.
Claims9
A fluid discharge device, comprising:
- a water tank 31 (or 41) comprising a hole 312a (or 412a) at an upper portion, a discharge port 311a (or 411a) at a side surface of a lower portion, a seat 311b (or 411b) of a plate for opening and closing the discharge port at a periphery of the discharge port;
- a discharge port valve 32 (or 42) in which a handle 322 (or 422) is coupled to a plate 321 (or 421) mounted in the seat to open and close the discharge port;
- a water passage 34 (or 44) having a water tank inlet 34a (or 44d) at an end portion and having the other end portion connected to a water supply pipe and for supplying water into the water tank;
- and
- a float valve 33 (or 43) for opening and closing the inlet of the water tank.

A fluid discharge device, comprising:
- a discharge port 2a formed at a side surface of a pipe;
- a discharge port valve 21 mounted at the inside of the pipe to change an opening sectional area of the discharge port while moving along the pipe by a change of a drag by a fluid or a change of a pressure of the upper stream side of the pipe;
- and
- a discharge port valve seat 2b formed at the inside of the pipe.

- and
- a discharge port 2a.
A fluid discharge device, comprising:
- a discharge port valve 24 comprising a closure member 241 having a deep groove 241a at the center of a front surface, an airfoil 243 for generating a lift, a support 242 for connecting the closure member and the airfoil, and a spring 244;
- a pin 2e;
- a pin fixing groove 2d;
- and
- a discharge port 2a.
