A slide valve gear forming a sliding fit with a casing body is arranged between an elastic membrane and an armature of an electromagnetic drive device. The casing body is provided with a liquid inlet channel and a liquid leakage channel which are communicated with an upper chamber and match with the slide valve. The utility model can be opened and closed flexibly and can be controlled accurately. The pressure difference can be used to realize control; thus, the valve device has high control precision and high response speed. The utility model is an ideal basic component matching with microcomputers. The utility model, which is suitable for frequent open and closure, has the advantages of compact structure, large flow control, safe work and longe service life. The valve device has the advantages of pilot-operated type slide valves and diaphragm valves, which is a power amplification device using small power signals to control large output power.
Description
The utility model relates to control a kind of valving of paper viscosity fluid.
Be used to control the electromagnetic valve of low viscosity fluid, common have guide electromagnetic valve and a diaphragm electromagnetic valve, and they are mainly by electromagnetic actuator device, and controlled spool and housing are several most ofly to be constituted.The controlled spool of guide electromagnetic valve is for to be the sliding valve structure that is slidingly matched with housing, electromagnetic actuator device is by the control of armature to spool displacement, realize the control of fluid delivery, this threshold switch is flexible, precise control, be specially adapted to the higher place of switching frequency, but it is not suitable for the bigger working link of working medium flow.The controlled spool of diaphragm electromagnetic valve is a flexible sheet, and it is suitable for doing big flow control usefulness especially, and its deficiency is unsuitable frequent switch, also has " water hammer " phenomenon, can not with the supporting use of microcomputer.
The purpose of this utility model is to avoid not enough here of the prior art, and provides a kind of switch flexible, and precise control is suitable for the electromagnetic valve product of frequent switch, big flow control again.
Can take following technological scheme to realize purpose.Except that electromagnetic actuator device, the controlled spool of flexible sheet and housing, also installation is the slide valve gear that is slidingly matched with housing between the armature of flexible sheet and electromagnetic actuator device, makes feed pathway A, the B and the current by pass C that match, link up upper chamber with guiding valve on the housing.Make solenoid electric valve product with guiding valve and the two controlled spools of flexible sheet.
In conjunction with the accompanying drawings, mode of execution is described in further detail the content of the technical program.
Fig. 1 is a kind of structural representation of this combined electromagnetic control valve
Fig. 2 is a slide valve gear opening state schematic representation.
The combined electromagnetic control valve from constitute go up say electromagnetic actuator device (1) is also arranged, controlled spool and several major parts of housing (11), wherein electromagnetic actuator device and prior art do not have difference; But the spool of the composite electromagnetic control valve flexible again diaphragm that is existing guiding valve constitutes link the successively double spool structure of control of electromagnetic actuator device, guiding valve, flexible sheet, and housing is also done corresponding improvement.Promptly between the armature (2) of flexible sheet (10) and electromagnetic actuator device (1), also be equipped with and be the slide valve gear that is slidingly matched, feed pathway A, the B and the current by pass C that match, link up upper chamber with guiding valve (4) are arranged on the housing with housing.The structural type of guiding valve, housing with matching, and structural factor such as the orientation of the shape of upper chamber, position, chamber size, feed pathway A, B current by pass C, trend and constituting all can select as one sees fit.
Slide valve gear mainly constitutes by contacting the upper diaphragm (3), guiding valve (4), driving spring (6), push rod (7) and the diaphragm return spring (8) that are installed in the housing successively in the accompanying drawing institute example; Upper diaphragm (3) contacts with armature (2), fixedlys connected with flexible sheet (10) in push rod (7) lower end, and Returnning spring (8) is sleeved on the push rod (7) between housing (11) and flexible sheet (10); Between housing (11) and guiding valve (4) valve pocket (5) is housed, valve pocket and housing close-fitting are fixed, and guiding valve and valve pocket are and are slidingly matched.The common combined electromagnetic control valve using effect the best that constitutes of this structure and flexible sheet.
When not having electric current in the coil of electromagnetic actuator device (1), promptly there is not electromagnetic action, armature (2) is in upper, and upper diaphragm (3), guiding valve (4), driving spring (6), push rod (7) are not produced active force; Resilient member upper diaphragm, driving spring, Returnning spring (8) and flexible sheet (10) all are in free state; Guiding valve is upper, cut off B, C path, ditch circulation passage A and B, working medium injects upper chamber (9) by A, B, balance each other with the working medium in the chamber of flexible sheet below, flexible sheet is closed medium channel under the effect of Returnning spring (pressure spring), promptly the combined electromagnetic control valve is in closed condition, as shown in Figure 1.When feeding direct current in the coil, be subjected to the electromagnetic force effect, armature moves down, and presses diaphragm, the sliding valve produces displacement downwards; Passage A is closed, and promptly cuts off A, B path, links up B and C, and the working medium in the upper chamber is by B, C earial drainage, and promptly upper chamber's internal pressure descends; And the pressure of elastic sheet below chamber is constant, pressure difference appears in upper and lower cavity, the elastic force of (8) that overcomes spring, with flexible sheet jack-up, open medium channel, promptly the combined electromagnetic control valve is in opening state, as shown in Figure 2.Power supply one cuts off, and flexible sheet resets under the effect of Returnning spring (8), is in closed condition again.
Illustrated example middle shell (11) is to be assembled by a plurality of members.
The relative prior art of the utility model has following advantage:
1, flexible, the precise control of complex-type electromagnetic-control valve switch can accurately reappear the signal of telecommunication to the Influence of Displacement of guiding valve, and the needed signal power of guiding valve is very little, realize control with pressure differential, so the control accuracy height, fast response time is and the matching used ideal basic member of microcomputer.
2, compact conformation is suitable for frequent switch, big flow-control, and it has the advantage of pilot operated spool valve and diaphragm valve concurrently, has overcome again their drawback, and working media is not had excessive demand, " water hammer " phenomenon can not occur, and is safe and reliable, Service life.
3, it is a power amplifier device, can be with the very little very big output power (flow) of power signal control.
