Title:
MULTI-WAY VALVE
Document Type and Number:
WIPO Patent Application WO/2019/169650
Kind Code:
A1
Abstract:
Disclosed is a multi-way valve, comprising a valve body (10) having a metering port (16), a collecting port (17), and a plurality of liquid inlets (15), wherein the liquid inlets (15) and the collecting port (17) penetrate a chamber (14) inside the valve body (10); two valve cores (21, 22) both extend into the chamber (14); the plurality of liquid inlets (15) are divided into two groups; and the two groups of liquid inlets (15) are both respectively arranged circumferentially, such that the two valve cores (21, 22) are rotated to control the two groups of liquid inlets (15) so that any one of the liquid inlets (15) in any group of liquid inlets (15) is able to selectively be in communication with the metering port (16). The multi-way valve has the following advantages: by means of the respective rotation of the two valve cores (21, 22), the two liquid inlets (15) are communicated with the metering port (16) at the same time, and the flow rates of oil flowing through the two liquid inlets (15) can be measured by the metering port (16); the two valve cores (21, 22) control the connection and disconnection between the liquid inlets (15) and the metering port (16), such that the way in which the oil flow is measured is more flexible; and the two valve cores (21, 22) control the liquid inlets (15), such that the number of individual wells connected to the valve body (10) is multiplied, and the superiority in high-pressure large-size applications where multiple wells are needed in a limited space is realized.
