Problems solved by technology

This kind of hydraulic multi-way reversing valve with only oil return port can no longer provide oil source for other working devices, and its function is relatively single.
However, in actual work, many times it is often necessary to increase the working mechanism when there is only one oil supply pump. At this time, it seems helpless to face the traditional multi-way reversing valve.

Embodiment Construction

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0018] Such as figure 2 As shown, a multi-way reversing valve with both oil supply and return includes a valve body 1, and a central hole 2, an oil supply passage 3 and an oil return passage 4 are arranged in the valve body 1, and the central hole 2 is arranged along the The valve body 1 is arranged in the axial direction, and the front end of the central hole 1 is an oil inlet 5, and one end of the oil supply passage 3 and the oil return passage 4 meets the end of the central hole 2 to form a three-way intersection port 6, the other ends of the oil supply passage 3 and the oil return passage 4 respectively extend in opposite directions and toward the outside of the valve body 1, the position corresponding to the t...

Abstract

The invention relates to a multi-way oil supply and return reversing valve which comprises a valve body, wherein the valve body is internally provided with a center hole, an oil supply passage and an oil return passage; the center hole is formed in an axial direction of the valve body; one end of the oil supply passage and one end of the oil return passage are intersected with the tail end of the center hole to form a tee-joint intersection; the other end of the oil supply passage and the other end of the oil return passage stretch towards opposite directions and towards the outer side of the valve body; an oil supply port communicated with the tee-joint intersection is formed in the valve body corresponding to the tee-joint intersection; a choke plug or a transition joint used for supplying oil to a next valve is arranged in the oil supply port. The reversing valve has the benefits that the multi-way reversing valve located on a series loop of a hydraulic system can realize oil supply to the next valve by improving a structure of a traditional hydraulic multi-way valve and additionally arranging the transition joint at an outlet of the multi-way reversing valve; when the oil supply is not required, the transition joint is taken down and replaced with the hydraulic choke plug.

Description

technical field [0001] The invention relates to the field of oil supply valves, in particular to a multi-way reversing valve with both oil supply and return. Background technique [0002] The hydraulic multi-way reversing valve commonly used in the market has only an oil return port at present. This hydraulic multi-way reversing valve with only an oil return port can no longer provide oil sources for other working devices, and its function is relatively single. However, in actual work, many times it is often necessary to increase the working mechanism when there is only one oil supply pump. At this time, it seems helpless to face the traditional multi-way reversing valve. If there is a Pb port in a hydraulic multi-way reversing valve (this port can provide oil source for other valves), then the problem will be solved easily. Through this valve, it can quickly and easily supply oil to other valves or stop oil supply. Convenient switching can greatly reduce the manufacturing...
