Embodiment Construction

[0017] In order to further illustrate the present invention, illustrate below in conjunction with accompanying drawing of description:

[0018] Referring to the accompanying drawings, the hydraulic rotary valve body casting includes a valve body 1, a vertical flow channel 2 and an annular groove 3. The valve body 1 is cylindrical, the upper end port of the valve body 1 is square, and the outer side of the valve body 1 is designed with a cylindrical protrusion. 4, a square block 5 is designed on one side of the valve body 1, a vertical flow channel 2 is opened inside the valve body 1, and an annular groove 3 is opened in the vertical flow channel 2.

[0019] The outer side of the valve body 1 is designed with cylindrical protrusions 4. There are three cylindrical protrusions 4 arranged in a triangle on one side of the valve body 1, and four cylindrical protrusions 4 are arranged in parallel on the other side of the valve body 1. Quadrilateral arrangement.

Abstract

The invention relates to the field of valve castings, in particular to a hydraulic rotation valve casting and a die thereof. The hydraulic rotation valve casting comprises a valve body, a vertical flow channel and annular grooves. The valve body is cylindrical. An opening in the upper end of the valve body is square. Cylindrical protrusions are designed on the outer side of the valve body. A square block is designed on one side of the valve body. The vertical flow channel is formed in the valve body. The annular grooves are formed in the vertical flow channel. The hydraulic rotation valve casting and the die thereof have the advantages that design is simple, use is convenient, ingenuity and reasonability are achieved, casting is convenient, the qualification rate of casting is greatly increased, the casting cost is reduced, the integration degree is high, reliability is high, and the service life is long. Promotion and progress of a current casting technology in China are facilitated, the situation that the precision of casting products of the same kind China is poor, and the technical content is low is changed, and great practical significance is provided for enlarging domestic and foreign market shares in the future.

Description

technical field [0001] The invention relates to the field of valve body castings, in particular to a hydraulic rotary valve body casting and a mold thereof. Background technique [0002] The hydraulic rotary valve body is an important part of the hydraulic rotary device, which is widely used in the transmission mechanisms of various machinery such as construction engineering, walking machinery, and oil field drilling. The quality of valve body castings determines the normal operation and safety of the supporting rotary device. At present, the functions of domestic and foreign project products are equivalent, and the difference is that similar foreign products have high precision and long service life. Hydraulic rotary valve body castings, as key components of hydraulic transmission rotary devices, are required to have the characteristics of high integration, high reliability and long life. However, the current casting technology needs to be improved and improved to cha...
