Active round-flow four-way water mixing heat exchange valve

Abstract

The invention discloses an active round-flow four-way water mixing heat exchange valve. The hollow part of a valve shell (1) is provided with a valve cavity (2); four openings are led out of the valve shell (1) from the valve cavity (2) in a communicating way; the valve cavity (2) is perpendicular to the plane on which the central lines of the four openings are positioned and penetrates through a crossing point of the central lines of the four openings to be fixed on a valve shaft (4) in the valve cavity (2) to fix a spherical round-flow plate (3); a part of outer edge is provided with an open cambered notch; the middle part of the spherical round-flow plate (3) has an elliptical cross section; a communicating part of a water inlet on the inner wall of the valve cavity (2) is provided with an elliptical inner water inlet which is matched with the open cambered notch on the outer edge of the spherical round-flow plate (3); the communicating part is provided with an approximately circular through hole; a long-axis part of the middle part of the round-flow plate (3) with the elliptical cross section changes the water inlet direction in the valve cavity (2), so that cold water and hot water are basically mixed in the same direction in the valve cavity (2) and are effectively prevented from being directly collided with each other in the valve cavity (2) face to face; therefore, noise and mechanical vibration are obviously reduced, and the device has a simple and practical structure and an obvious energy-saving effect.

Description

Technical field: [0001] The invention belongs to a heat exchange four-way valve device on a hot water pipeline and belongs to the field of heat exchange devices. Background technique: [0002] In the prior art, the valve plate of the traditional four-way valve is in the shape of a flat plate, so the water flowing into the valve cavity from the two water inlets directly collides head-on, which will generate relatively large water flow noise and resistance. When the angle rotation is opened or closed, there is only a positive correlation between the flow rate formed by the cross section of the water flow channel formed by the valve core and the water inlet gap in the valve body, but not a linear relationship, resulting in inaccurate and inconvenient control of the outlet flow and water temperature. Invention content: [0003] The purpose of the present invention is to provide a water mixing valve which avoids the direct collision of the cold and hot water flowing into the va...
