Description
Technical field
The utility model relates to a kind of double-flow-rate electromagnetic valve of employing plastic material piston type main valve structure of oilling machine, belongs to oilling machine Solenoid Valve Technology field.
Background technique
In the double-flow-rate electromagnetic valve of existing oilling machine, general by coil block, valve body, valve gap, small flow pilot head component, large-flow-rate pilot head group part, elastomer diaphragm assembly forms, using valve body and valve gap as architecture basics, valve body top is provided with a small flow pilot head component and a large-flow-rate pilot head group part, two pilot head component tops are provided with a coil block, this coil inside contains two coil winding, control the action of two pilot head component respectively, in the cavity between valve body and valve gap, be provided with an elastomer diaphragm assembly; During this electromagnetic valve work, be divided into small flow and large discharge, when small flow pilot head component is by coil adhesive, tiny flow passages is opened, and when large-flow-rate pilot head group part is by coil adhesive, large discharge passage is opened; Main valve is elastomer diaphragm modular structure, elastomer diaphragm is wherein as part most important in main valve, because diaphragm self action needs, thinner and soft, adding to be in for a long time has in corrosive gasoline, diesel oil, and occurring wearing and tearing with the repeatedly closed middle of metal valve port, then sealing station is thinning, cause solenoid valve main valve to occur internal leakage, finally make oilling machine volume read-out occur relatively large deviation.
Summary of the invention
The purpose of this utility model is to provide a kind of double-flow-rate electromagnetic valve of piston type main valve, can be used in oilling machine, and the organic solvent such as gasoline, the diesel oil corrosion of the various heterogeneity of ability, valve mechanism is simple, and the main valve life-span can reach more than 1,000,000 times.The following technological scheme of concrete employing:
A double-flow-rate electromagnetic valve for piston type main valve, comprises coil block, valve body, valve gap, small flow pilot head component, large-flow-rate pilot head group part, the double-flow-rate electromagnetic valve of described piston type main valve, is provided with a piston between valve body and valve gap; Be provided with a main valve diaphragm seal between described piston and valve body, described main valve diaphragm seal is fixed on piston; Described piston is loaded in the endoporus of valve gap, is provided with a spring between described piston and valve gap endoporus bottom outlet; Described piston and valve gap endoporus hole wall are provided with a seal ring; Described piston is provided with an aperture, through to valve body side rifle body and valve gap side rifle body respectively.
The double-flow-rate electromagnetic valve of above-mentioned piston type main valve, described piston adopts plastic material.
The double-flow-rate electromagnetic valve of above-mentioned piston type main valve, its advantage is:
1. good stability, the life-span is long.Have employed the piston of plastic material in described main valve, under various oil product, there is fabulous stability; Main valve diaphragm seal that is described and primary valve fitted seal, thickness can be more than 3 times of normal film chip, after can ensureing 1,000,000 actions, when there are appropriateness wearing and tearing, still possesses sealability.
2. structure is simple, easy to maintenance.Described piston adopts plastic material to adopt molding and forming, and the guide's aperture on piston also can straight forming thereupon; Described main valve diaphragm seal and seal ring are installed, it is convenient to change.

In Fig. 1,1: coil block, 2: small flow pilot head component, 3: main valve diaphragm seal, 4: seal ring, 5: valve gap, 6: piston, 7: spring, 8: piston aperture, 9: valve body, 10: large-flow-rate pilot head group part
Embodiment
As shown in Figure 1, a kind of double-flow-rate electromagnetic valve of piston type main valve, comprise coil block 1, valve body 9, valve gap 5, small flow pilot head component 2, large-flow-rate pilot head group part 10, the double-flow-rate electromagnetic valve of described piston type main valve, a piston 6 is provided with, as the carrier of main valve Sealing between valve body 9 and valve gap 5; Be provided with a main valve diaphragm seal 3 between described piston 6 and valve body 9, described main valve diaphragm seal 3 is fixed on piston 6; Described piston 6 is loaded in the endoporus of valve gap 5, is provided with a Compress Spring 7, for the sealing of main valve diaphragm seal 3 provides pretightening force between described piston 6 and valve gap 5 endoporus bottom outlet; Described piston 6 is provided with a seal ring 4 with valve gap 5 endoporus hole wall, and the internal cavity for solenoid valve seals; Described piston 6 is provided with a piston aperture 8, i.e. guide's aperture, through to valve body 9 side rifle body and valve gap 5 side rifle body respectively.
The double-flow-rate electromagnetic valve of above-mentioned piston type main valve, described piston 6 adopts plastic material.
The double-flow-rate electromagnetic valve of above-mentioned piston type main valve, its work process is as follows:
Small flow pilot head component 2 adhesive after corresponding coil winding energising, small flow valve port is opened, and goes into lasting small flow oil passage;
Large-flow-rate pilot head group part 10 adhesive after corresponding coil winding energising, poppet port in large-flow-rate pilot head group part 10 is opened, and fluid enters from the oil suction chamber between piston 6 and valve body 9, by piston aperture 8, enter large-flow-rate pilot valve port, then flow into out oil pocket; Diameter due to piston aperture 8 is less than large-flow-rate pilot valve port, cause oil suction chamber and go out oil pocket forming pressure reduction, then promote the pressure that piston 6 overcomes spring and move to bottom flange 5 side, namely main valve diaphragm seal 3 leaves primary valve, final primary valve is opened, and large discharge oil passage is formed.
