Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0025] Depend on figure 1 combine Figure 2-8 As shown, a mechanical non-leakage multi-way valve includes a valve body 1 and a valve stem 2. The valve body 1 is provided with an oil inlet P, an oil outlet T, a first working port A, and a second working port. port B and cavity 11, the valve body 1 is provided with a one-way valve 3 with hydraulic lock function, and the one-way valve 3 is set between the cavity 11 and the second working port B, and the The valve stem 2 has a first position where the pressure oil at the oil inlet P communicates with the second working port B through the cavity 11 and the check valve 3, and at the same time makes the first working port A communicate with the oil outlet T, so that the oil inlet The port P is connected with the oil outlet T and the pressure oil of the second working port B passes through the second position wher...

Abstract

The invention provides a mechanical leakage-free multi-way valve, and solves the problems that pressure oil on existing agricultural machinery cannot be stored, the oil leaks, and the pressure is notstable. The mechanical leakage-free multi-way valve comprises a valve body and a valve rod, wherein an oil inlet, an oil outlet, a first working port, a second working port and a cavity are formed inthe valve body; a one-way valve with a hydraulic lock function is arranged in the valve body, and is arranged between the cavity and the second working port; the valve rod has a first position, a second position and a third position; when the valve rod is located at the first position, the pressure oil of the oil inlet communicates with the second working port via the cavity and the one-way valve,and meanwhile, the first working port communicates with the oil outlet; when the valve rod is located at the second position, the oil inlet communicates with the oil outlet, and the pressure oil of the second working port is locked by the one-way valve; and when the valve rod is located at the third position, the one-way valve is opened to allow the second working port to communicate with the oiloutlet. The mechanical leakage-free multi-way valve further has the advantages of simple structure, convenience in assembly, reliable action, long service life and the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a mechanical non-leakage multi-way valve. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. Agricultural machinery in a broad sense also includes forestry machinery, fishing machinery, and rural sideline machinery such as sericulture, beekeeping, and edible fungus cultivation. Agricultural machinery is a relative concept, which refers to the general...
