Abstract
The utility model discloses a double-acting integral multiport valve, which comprises a valve body (1), a main overflow valve (2), a work port (3), an oil inlet (4), an oil outlet (5) and an operating lever (6), wherein the operating lever (6) is arranged under the valve body (1), and the valve body (1) adopts an integral structure. The upper portion of the valve body (1) of the multiport valve is provided with a reversing switch (7), and the lateral surface of the valve body (1) is provided with a media outlet (8). With the structure, the double-acting integral multiport valve has compact structure, small volume, convenient manufacture and material saving, and meanwhile, the integral structure further avoids generating the leakage phenomenon between each valve block, thereby reducing liquid inlet pressure loss and liquid return pressure loss, and guaranteeing an excellent work state, in addition, the reversing switch arranged on the upper portion of the valve body leads single-acting and double-acting conversion to be flexible and convenient.
Description
Technical field
The utility model relates to a kind of control valve unit, especially relates to a kind of double-acting integral multi-way valve.
Background technique
At present, in field of agricultural machinery,, adopt hydraulic multitandem valve in order to realize holding functions such as mechanical lifting, advance and retreat more.Hydraulic multitandem valve mainly comprises component compositions such as valve body, operating handle, main relief valve and filler opening, return opening, wherein valve body is general adopts a plurality of valve blocks to assemble making side by side, this hydraulic multitandem valve complex structure, volume is bigger, it is all very inconvenient to assemble, dismantle, keep in repair, particularly in use, because each valve block is a package assembly arranged side by side, its overall sealing performance is unreliable, leakage phenomenon often takes place between valve block and valve block easily, thereby it is excessive to cause into, return the hydraulic coupling loss, can not guarantee the works fine state of multi-way valve.In addition, for existing multi-way valve, because structural reason, also underaction is light in its single double-acting conversion.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and a kind of compact structure is provided, and can prevent that valve body from leaking the double-acting integral multi-way valve of the two conversions of practicable list.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises valve body, main relief valve, working hole, filler opening, oil outlet and operating stem, and operating stem is located at valve body lower portion, and described valve body adopts monolithic construction.
Valve body described in the utility model top is provided with reversing switch, and the valve body side is provided with a meta delivery outlet.
The said structure that the utility model adopts, because valve body adopts integrated type, compact structure, volume is little, and is easy to make, saved material; Simultaneously, overall structure has also been avoided the leakage phenomenon that produces between each valve block, reduces, returns the hydraulic coupling loss, has guaranteed good working order; In addition, the reversing switch that valve body top is provided with makes that single double-acting conversion is light flexibly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Figure 1 shows that plan view of the present utility model
Figure 2 shows that left view of the present utility model
Figure 3 shows that the A-A cut-away view among Fig. 2
Embodiment
By accompanying drawing as can be known, this kind double-acting integral multi-way valve comprises valve body 1, main relief valve 2, working hole 3, filler opening 4, oil outlet 5 and operating stem 6, and operating stem 6 is located at valve body 1 bottom, and described valve body 1 adopts monolithic construction.Valve body 1 top of multi-way valve is provided with reversing switch 7, and valve body 1 side is provided with a meta delivery outlet 8.Described valve body can adopt cast inblock, makes through machining.The integral multi-way valve can adopt two way reversing valves, establishes relief valve, one-way valve in the valve body, the relief valve adjustable in pressure, and one-way valve prevents that fluid from flowing backwards, the selector valve slide valve function has A, O, Y etc., can combination in any.This valve adopts oil circuit in parallel, is provided with two return openings, can realize being communicated with or separately by Rc1/4 plug-hole on the reversing switch, turns to 90 ° to block the Rc1/4 hole meta return opening is exported as a pressure, and joining with other hydraulic element provides power source.Can realize single double-action flexibly easily by the rotation reversing switch.The utility model is with the described scope of soverlay technique scheme; and the various modification of claim scope and equivalence variation; under the prerequisite that does not depart from technical solution of the present utility model, any modification or improvement that those skilled in the art that the utility model is done realize easily all belong to the utility model scope required for protection.
Claims (2)
