Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] The structure of the manual reversing valve of the present invention is as follows: figure 1 As shown, it includes: handle 10, support 20 and support frame 21, push rod 30, valve body 50 and pin shaft 51, when installing the manual reversing valve in the hydraulic system, it also includes installation panel 40, fixing nut 41 and other components.

[0027] Support structure such as figure 2 with image 3 As shown, there is a support hole 22 on the support 20, the push rod 30 is prevented in the support hole 22, and the inner diameter of the support hole 22 matches the outer diameter of the push rod 30, the support frame 21 is set on the support 20, two pieces Support holes 25 are respectively provided on the support frame 21 . In a preferred solution, a first groove 23 is also arranged in the seat hole 22, and a sealing ring is arranged in the first groove 23. T...

Abstract

The invention discloses a longitudinal-operating-type manual reversing valve which comprises a handle, a support, a support frame, a push rod, a valve body and a pin shaft. The support frame is arranged on the support, the operating handle is hinged on the support frame, a handle shaft is arranged at one end of the handle and connected with the upper section of the push rod, and the lower section of the push rod is connected with the valve body and the pin shaft. Consequently, the operating mode of the manual reversing valve is converted from horizontal operating into longitudinal operating, and intuitive sense of people and requirements on humanized operation are met better; the lever principle is utilized, and the handle is operated by taking the support frame as a supporting point, so that operation is more labor saving.

Description

technical field [0001] The invention relates to a reversing valve, in particular to a manual reversing valve. Background technique [0002] The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes communication, cutting and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. Manual reversing valves are often used in hydraulic control systems to manually control the flow direction of hydraulic oil. The ordinary manual reversing valve in the prior art is suitable for horizontal installation, and the reversing is realized by the front and rear operation of the handle, but the front and rear operation methods do not fully meet the requirements of humanized operation methods, and there is a problem of laborious operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manual reversing valve op...
