Title:
FLOAT TYPE DRAIN TRAP AND METHOD FOR DISCHARGING DRAIN WATER
Document Type and Number:
Japanese Patent JP2014098474
Kind Code:
A
Abstract:

To provide a float-type drain trap capable of discharging drain water in a stable manner even if impurities such as dust and the like are adhered to the drain trap or a variation is present including a dimension error.

A float 20 moving-up and down, a valve body 51 for opening and closing a valve seat 15 and a valve arm 52 etc. are integrally constituted; an opening and closing valve 50 swinging around a valve swinging shaft 72 is also integrally constituted; and a hole 20a formed at the extremity end of a spring arm 23 of the float 20 and a spring bearing 53 positioned at the extremity end of the valve arm 52 of the opening and closing valve 50 are integrally connected through a spring 60 including a twist coil spring 60. A connecting part between the spring 60 including the twist coil spring 60, float 20 and opening and closing valve 50 is swingably and movably constituted. The spring 60 is pushed and shrunk with buoyancy of the float 20 so as to open and close the valve seat 15 connected to a discharging port 10b with a force of the pushed and shrunk spring 60, and thereby intermittently discharging drain water.
