Embodiment Construction

[0019] Further description will be given below through specific embodiments and in conjunction with the accompanying drawings.

[0020] The main structure of the present invention includes an upper valve body 1, a lower valve body 5, and a valve disc 2, and the upper valve body 1 and the lower valve body 5 are integrally connected and fixed on the base. The upper valve body 1 and the lower valve body 5 form a disc-shaped cavity inside to accommodate the valve disc 2. The valve disc 2 fits with the upper valve body 1 and the lower valve body 5 with a small gap and can rotate flexibly around the axis.

[0021] The upper valve body 1 is generally disc-shaped from the outside, with a cylindrical cavity inside, and two liquid flow ports, oil port B7 and oil port C8, are opened on the upper end surface for oil in and out; the axial center position of the upper end surface There is a turntable hole, and the rotating shaft of the valve disc 2 protrudes from the turntable hole; the ope...

Abstract

The invention relates to a two-position three-way rotating disc type reversing valve, and belongs to the field of hydraulic transmission. A main structure comprises an upper valve body, a valve disc and a lower valve body, wherein the upper valve body and the lower valve body are connected into a whole by bolts and nuts and are fixed to a base; the valve disc is installed in a cavity formed by the upper valve body and the lower valve body, and a driving shaft of the valve disc extends from the upper valve body so as to drive the valve disc to rotate by virtue of external power; an oil port B and an oil port C are formed in the upper valve body, and an oil port A is formed in the lower valve body; when the valve disc rotates, the oil port A communicates with the oil port B in the first half cycle, and the oil port A communicates with the oil port C in the second half cycle; and the valve disc continuously rotates, so that a two-position three-way operating mode of the reversing valve is realized. According to the two-position three-way rotating disc type reversing valve, the operating mode of a traditional two-position three-way electromagnetic directional valve which is reversed by reciprocating movement of a valve core is broken, the two-position three-way rotating disc type reversing valve has the characteristics of compact structure, easiness in processing, stability in operation, low noise and the like, and application requirements and industrial prospects are wide.

Description

technical field [0001] The invention belongs to the field of hydraulic transmission, and in particular relates to a two-position three-way turntable reversing valve. Background technique [0002] Hydraulic transmission is widely used in modern industry. On-off valve is an important control valve in hydraulic system, and its working performance has a very important influence on the whole hydraulic system. At present, most of the two-position three-way switching valves commonly used in hydraulic systems are slide valve structures, and there are three oil ports on the valve body: oil port A, oil port B, and oil port C. The spool has two positions, one of which connects oil port A with oil port B, and the other connects oil port A with oil port C, so that the switching of two load working oil circuits can be realized. However, due to the complex structure and shape of the valve body and the valve core, high matching precision is required, resulting in high manufacturing process...
