Abstract
The utility model relates to a multi-way reversing valve, which comprises a main valve body. An oil inlet is arranged at one end of the main valve body, an oil return opening is arranged at the other end of the main valve body, a plurality of valve chambers are arranged on the main valve body between the oil inlet and the oil return opening, the plurality of valve chambers are communicated through a series-connection oil way, the oil inlet is communicated with one end of the series-connection oil way, and the oil return opening is communicated with the other end of the series-connection oil way. An oil return valve sheet, an oil inlet valve sheet and a plurality of reversing valve sheets which are originally manufactured respectively and independently are evenly arranged on the valve body, and the main valve body is integrally molded in casting mode, thereby being simple to manufacture, good in strength of an overall structure and capable of effectively avoiding oil leakage. No sealing ring is needed to be arranged between each different functional unit, and the multi-way reversing valve is ideal in performance.
Description
Technical field
The utility model relates to the selector valve technical field, relates in particular to a kind of multiple directional control valve.
Background technique
In the existing technology, the structure of multiple directional control valve has multiple, wherein has a kind of the assembling by a plurality of valve blocks for valve body to constitute structure; Concrete: this kind multiple directional control valve comprises a plurality of Reversing valve plates and is provided with the oil-feed valve block of filler opening, is provided with return opening and gets the oil return valve block that when assembling, oil-feed valve block and oil return valve block are positioned at two ends; In the middle of a plurality of Reversing valve plates are positioned at, and fixing with the screw rod serial connection, install cumbersome during manufacturing; And; For sealing needs, seal ring also to be set between each adjacent parts seal, but in the course of the work; Receive the influence of external force or other factors; The overall structure of this multiple directional control valve very easily deforms, at this moment between each Reversing valve plate, between oil return valve block and the Reversing valve plate and all the oil impregnate phenomenon can occur between oil-feed valve block and the Reversing valve plate, make that the performance of multiple directional control valve is not ideal enough.
Summary of the invention
For solving above-mentioned technical problem, the utility model provides a kind of make simple, the comparatively desirable multiple directional control valve of performance.
The technological scheme of the utility model is, a kind of multiple directional control valve with following structure is provided, and it comprises main valve body; One end of described main valve body is provided with filler opening; The other end is provided with return opening, on the main valve body between filler opening and the return opening, is provided with a plurality of valve pockets, and described a plurality of valve pockets are communicated with through the serial connection oil circuit; Described filler opening is communicated with an end that is connected in series oil circuit, and return opening is communicated with the other end that is connected in series oil circuit.
After adopting said structure, the utlity model has following advantage:
Oil return valve block, oil-feed valve block and a plurality of Reversing valve plate of separate manufacturing all were arranged on the valve body respectively with originally; Main valve body is one-body molded through the mode of casting; Make simply, integrally-built intensity is also relatively good, can effectively avoid the generation of oil impregnate phenomenon; Also just seal ring need be set between each different functional units, the performance of multiple directional control valve is also comparatively desirable.
Description of drawings:
Fig. 1 is the structural representation of the utility model multiple directional control valve;
Embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in Figure 1, the utility model multiple directional control valve, it comprises main valve body 1; One end of described main valve body 1 is provided with filler opening 2; The other end is provided with return opening 3, on the main valve body 1 between filler opening 2 and the return opening 3, is provided with a plurality of valve pockets 4, and described a plurality of valve pockets 4 are communicated with through the serial connection oil circuit; Described filler opening 2 is communicated with an end that is connected in series oil circuit, and return opening 3 is communicated with the other end that is connected in series oil circuit.
After adopting said structure, original remaining part can be done adaptive variation dimensionally for adapting to the structure of main valve body 1 in the multiple directional control valve, and their mounting point and self structure then need not to change.
