WIPO Patent Application WO/2023/143073
Kind Code:
A1
Abstract:
Provided is a valve device. A valve seat component comprises a valve seat sleeve and a flange portion, wherein an opening portion at the lower end of a sleeve is welded and fixed to the valve seat sleeve. The valve device further comprises a mounting block. The valve device is mounted on another component by means of the mounting block. The mounting block is further provided with a mounting hole in which part of the valve seat component is located. The diameter of at least part of the mounting hole is less than the outer diameter of the flange portion. The flange portion limits the mounting block to be separated from the valve seat component in a direction away from a coil assembly. The valve device further comprises a gasket, wherein at least part of the gasket is located between the valve seat component and an inner peripheral wall surrounding the mounting hole, and the gasket is pressed between the mounting block and the valve seat component by means of interference fit to limit the circumferential rotation of the valve seat component relative to the mounting block. Such an arrangement is beneficial to limiting the circumferential rotation of a valve component relative to the mounting block or a valve body, such that the mounting of the valve device can be facilitated.
