Abstract

The invention provides an electrically driven valve and a manufacturing method thereof, wherein the material cost and the processing cost of a valve core can be suppressed, and the manufacturing cost can be reduced. A solenoid valve (1) is provided with: a cylindrical valve body (10) having a closed upper end; a valve seat member (20) joined to the lower end of the valve body (10); and a valve body (40) housed in the valve body (10). The valve seat member (20) has: a cylindrical valve seat body (21) having a valve seat (22) provided at the upper end thereof; and an annular plate-shaped flange (23) joined to the valve body (10), the flange being provided so as to be continuous with the lower end of the valve seat body (21). The valve body (40) is provided with a cylindrical body part (41) and an annular plate-shaped valve part (42) which is in contact with and separated from the valve seat (22), and the valve part and the main body part (41) are continuously arranged. The valve body (10), the valve seat member (20), and the valve body (40) are formed by metal stamping.

Description

technical field [0001] The present invention relates to an electrically driven valve and its manufacturing method. Background technique [0002] Patent Document 1 discloses a conventional solenoid valve as an electrically driven valve. The solenoid valve disclosed in Patent Document 1 has a cylindrical valve body with one end closed, a base member joined to the other end of the valve body, and a valve body accommodated in the valve body so as to contact and separate from a valve seat of the base member. . [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-185603 [0006] The problem to be solved by the invention [0007] In the solenoid valve of Patent Document 1, a columnar valve body is produced by cutting a brass material. Therefore, material costs and processing costs increase, leading to an increase in the manufacturing cost of the solenoid valve. Contents of the invention [0008] Therefore, a...
