Embodiment Construction

[0019] The Kawasaki KMX15RA multi-way valve of the present invention has an optimized structure for the right-hand travel channel, including a multi-way valve body, and there is a section C-D between the main oil inlet of the right-hand travel joint of the multi-way valve and the two working oil ports A and B The public flow channel, the public flow channel in section C-D is composed of convex arc-shaped side walls and convex corner-shaped side walls QKR on both sides. Such as Figure 10 As shown, the convex corner-shaped side wall QKR has an arc-shaped chamfer at the corner, so as to reduce the pressure loss of the common flow channel of the C-D section.

[0020] In the embodiment of the present invention, the value range of the radius of the arc-shaped chamfer is 10mm~50mm. Wherein, the optimal value of the radius of the arc-shaped chamfer is 50mm.

[0021] In order to make the flow channel have a better use effect, the distance a from the corner point K of the convex corn...

Abstract

The invention relates to an optimized structure of a channel of a right flowing pair of a Kawasaki KMX15RA multi-way valve. The optimized structure comprises a multi-way valve body, wherein a C-D section public channel is arranged between a main oil inlet of the right flowing pair of the multi-way valve to two working oil port, the C-D section public channel is composed of convex arc-shaped side walls on two sides and a convex corner-shaped side wall QKR, and an arc-shaped chamfer angle is arranged at a position of a corner of the convex corner-shaped side wall QKR, so that the pressure loss of the C-D section public channel is reduced. The structure is beneficial to the reduction of the pressure loss of the channel inside the right flowing pair of the multi-way valve.

Description

technical field [0001] The invention relates to an optimization structure of a flow channel for right traveling connection of a Kawasaki KMX15RA multi-way valve. Background technique [0002] At present, excavators of various brands and models use Kawasaki KMX15RA multi-way valve as the main control valve. In the prior art, there is a C-D section public flow channel between the main oil inlet of the right-hand traveling union of the Kawasaki KMX15RA multi-way valve and the two working oil ports. The convex arc-shaped side walls and the The convex corner-shaped side wall will form a throat in the middle of the flow channel, resulting in a large pressure loss in the common flow channel of the C-D section. Therefore, it is necessary to optimize the design of the flow channel of the Kawasaki KMX15RA multi-way valve right-hand drive to reduce its pressure loss. Contents of the invention [0003] The purpose of the present invention is to provide an optimization structure of t...
