Abstract
The utility model discloses a multi-function compound hydraulic valve, which adopts a plate type connection. The utility model is composed of a lead electromagnetic valve and four-way blocks of the two-way cartridge valve. The utility model is characterized in that a cover body is controlled by the lead electromagnetic valve; the four-way blocks of the two-way cartridge valve is arranged on the bottom of the utility model, which is suitable for the hole sitting of the plate type connection. Compared with a traditional and common slide valve, the utility model has the same volume and external shape, and costs not much than a traditional and common slide valve. The functions of the utility model are more than a traditional and common slide valve. The utility model behaves as a plurality of sliding valves combined together.
Description
The present invention is a kind of hydrovalve, and it belongs to hydraulic control technology.Hydrovalve and be subjected to be connected with multiple mode between the workpiece of its control is as board-like connection, scyewed joint, flange connection etc.Wherein, practical with board-like connection generalization the most, be more suitable in batch process, economic benefit is the most remarkable.At present except that common slide valve (electro hydraulic valve) etc. with the board-like connection, still do not have the valve of seeing other and adopt board-like connection.Yet common slide valve function singleness, single valve can not adapt to variation that developed hydraulic industry requires control technique, complicated.A plurality of valves combine, and volume, cost all must have bigger increase, and are uneconomical economically, technical can not be satisfactory.
The objective of the invention is to overcome existing above-mentioned difficulties in the prior art and a kind of complex hydraulic valve with multiple function that adopts board-like connection is provided.
Task proposed by the invention is finished by following measure: control two-way plug-in valve four-way piece with pilot solenoid valve by the control lid, thus the motion of Control work load.Be suitable for the cloth hole of board-like connection in four-way piece bottom.
Below the present invention will be described in detail in the drawings.
Fig. 1 is the schematic diagram of multi-functional combination valve.
Fig. 2 is the structural drawing of multi-functional combination valve.
Fig. 3 is a four-way piece bottom cloth hole pattern.
The present invention controls lid 2 by pilot solenoid valve 1, and the bottom is made up of the two-way plug-in valve four-way piece 3 that is suitable for board-like connection cloth hole.A kind of feasible concrete structure is seen Fig. 2, Fig. 3.
Its basic commutation function principle is as follows: 15,16,17 be one-way valve, control oil enters combination valve from 11 circuits, and 10 and 12 is the working interface of combination valve and load, and 13 and 14 is fuel tank.When electromagnet 4 and 5 equal no electric circuits, control oil enters the control chamber of cartridge valve 6,7,8,9 respectively simultaneously from import 20 18 and 19 mouthfuls by solenoid valve 1, makes this four cartridge valve Close Alls.When 4 energisings, during 5 no electric circuits, then control oil content and do not enter 7 and 9 control chamber, make 7 and 9 to close; And 6 and 8 control chamber is connected with fuel tank respectively, makes 6 and 8 to be opening state.Working oil stream flows into 12 from 11 through 8, promotes load, flows back to fuel tank 13 from 10 through 6 from the oil return of load.If 4 no electric circuits and 5 the energising, then 6 and 8 close, 7 and 9 unlatchings.So far, realized commutation function.
If we increase the flow controller 22,23 of control spool aperture on 7 or 8, as the spool stroke regulating lever, then can realize the meter in function, also can on 6 or 9, add flow controller, then realize the meter out function.
If on 6 and 9, add pilot pressure valve 24 or 25.The then installation of 24 valves can make combination valve have the back pressure function; The installation of 25 valves makes combination valve have the pressure limiting function.The structure of Fig. 2 is a while pressure increase valve 24 on 6 and 9, and certainly a while pressure increase valve 25 perhaps is added on 6 and 9 simultaneously with 24,25.
The present invention compares with the common slide valve of the board-like connection of existing employing, and profile, volume, cost are similar, and that function is wanted is many.A multi-functional complex hydraulic valve is equivalent to the combination of several common slide valves with regard to function.Thereby more can adapt to the development of hydraulic industry.
