Title:
LIQUID PRESSURE-FEED DEVICE
Document Type and Number:
Japanese Patent JP2022050957
Kind Code:
A
Abstract:
To provide a liquid pressure-feed device excellent in durability and capable of rapidly and appropriately discharging liquid.SOLUTION: When drain flows into a valve chest 10 through a drain inlet 71 from a state shown in Fig. 1 (valve closed state), a float 3 is floated and valve holes 2a, 2b, 2c, 2d are opened (valve opened state). The float 3 is continuously floated, and thereby, an upper surface of the float 3 pushes up a connecting lever 61 (pressure-feed state), and a lower selector valve 64 fixed by an opening and closing bar 63 opens a lower valve hole 68a. Therefore, high pressure steam flows in from a steam inlet 73, and the drain is discharged and pressure-fed from the valve holes 2a, 2b, 2c, 2d through a drain outlet 72. The float 3 is turned around a support bar 4 by receiving inflow pressure of the drain flowing in from the drain inlet 71, and a portion of an outer peripheral curved surface of a bottom of the float 3 which closes the valve holes 2a, 2b, 2c, 2d is switched, and abrasion of the float 3 can be avoided.SELECTED DRAWING: Figure 1
