Multi-passage valve body casting

Abstract

The invention relates to a multi-passage valve body casting. The multi-passage valve body casting comprises a valve body, horizontal flow passages, a longitudinal flow passage and flow passage ports, the valve body is shaped like a cuboid, the two horizontal flow passages are arranged side by side in the valve body, the lower ends of the two horizontal flow passages communicate with each other via the longitudinal flow passage, the front and back of the valve body are respectively provided with two flow passage ports which communicate with the two horizontal flow passages, the middle parts of the two horizontal flow passages are respectively provided with three annular grooves, the upper ends of the annular grooves of the upper ends of the horizontal flow passages are provided with through holes, the openings of the through holes are located on the valve body, the left side of the middle annular groove of the left horizontal flow passage is provided with a through hole, the opening of the through hole is located at the left side of the valve body, the right side of the middle annular groove of the right horizontal flow passage is provided with a through hole, the upper ends of the annular grooves of the lower ends of the horizontal flow passages are provided with through holes, and the right side of the longitudinal flow passage is provided with a through hole. The multi-passage valve body casting has the following advantages: the design is simple, the multi-passage valve body casting is convenient to use and cast, and is ingenious and reasonable, the casting percent of pass is increased greatly, and the casting cost is reduced.

Description

technical field [0001] The invention relates to the field of valve body castings, in particular to a multi-way valve valve body casting. Background technique [0002] Multi-way valve products are mainly used for supporting various hydraulic pumps, and are widely used in various mechanical hydraulic systems. At present, the level of development at home and abroad is comparable, and the advantages of foreign products are reflected in their long service life. At present, similar domestic castings have poor precision and low technical content, and domestic high-end hydraulic components have long relied on imports. [0003] At present, the multi-way valve body castings have always been difficult to cast. The internal flow channel design of the valve body must meet the design requirements, and it must be able to be successfully cast. The main hole is broken during casting, the main hole is bent, and the straightness is greater than 0.6mm. Problems such as fracture and deformatio...

[0003] At present, the multi-way valve body castings have always been difficult to cast. The internal flow channel design of the valve body must meet the design requirements, and it must be able to be successfully cast. The main hole is broken during casting, the main hole is bent, and the straightness is greater than 0.6mm. Problems such as fracture and deformation of side holes near the mouth
