Patent Searching and Data


Title:
弁を操作する方法
Document Type and Number:
Japanese Patent JP5497886
Kind Code:
B2
Abstract:
A valve including a first valve part with at least one opening and a second valve part with at least one opening. The relative position of the openings of the first and second valve parts produces an overlapping area, which defines an opening degree of the valve. The first and second valve parts are adapted to perform relative movements from a position defining a maximum opening degree of the valve towards a position defining a minimum opening degree of the valve in such a manner that the velocity of the relative movement between the first valve part and the second valve part varies as a function of the overlapping area of the openings of the first and second valve parts. For example, the velocity may be decreased as the overlapping area decreases. Operating the valve in this manner reduces water hammering while ensuring appropriate operation and acceptable response times.
