Description
Technical field
This utility model relates to electromagnetic valve, specifically refers to a kind of slow opening apparatus of electromagnetic valve.
Background technology
Natural gas, when pipeline carries, uses electromagnetic valve to control the conveying of natural gas, the unlatching of general solenoid valve and pass
Closing is all quickly to open and quick closedown, though or have the device that protecting against shock opens slowly, but not there is end buffer speed and can be in harmonious proportion
The adjustable function of end cushion stroke, it is impossible to meet the requirement used.Patent No. ZL201320340849.4 discloses a kind of electricity
Magnet valve adjusting means, the speed governing knob in oil back chamber arranges speed governing oil return from shallow to deep corresponding to the surface of revolution of return port
Groove, adjusts buffer speed；Utilize the stroke drain pan of the superficial-helical of idle stroke adjusting knob, change end stroke.Above-mentioned
Structure can preferably solve protecting against shock and open slowly, and has end buffer speed and can be in harmonious proportion the adjustable function of end cushion stroke.But
Between said structure axis and base, it is respectively adopted sealing ring between cylinder body and base and carries out sealing it occur frequently that permeability phenomenon.
Summary of the invention
The purpose of this utility model is for the problems referred to above, it is provided that a kind of good airproof performance, service life, the electromagnetic valve of length was slow
Opening apparatus.
The technical solution of the utility model is: a kind of slow opening apparatus of electromagnetic valve of the present utility model, and it includes cylinder body,
There are oil pocket and oil back chamber on cylinder body, have flow adjustment knob at the top of cylinder body, have in oil pocket equipped with piston and reply bullet
The axis of spring, has return port between oil pocket and oil back chamber, have speed governing knob in oil back chamber, and above-mentioned speed governing knob corresponds to return port
Surface of revolution have speed governing oil-recovery tank from shallow to deep, cylinder body has an idle stroke adjusting knob, above-mentioned idle stroke regulates
There is spiral helicine stroke drain pan on the surface of knob, it is characterised in that on axis, has a fluid sealant between cylinder body and base
Film, above-mentioned sealed Cellophane is the trapezoidal shape on band base, and there is a column structure at its center, and above-mentioned column structure is fixed in being embedded in
In the groove of axle, the base of above-mentioned sealed Cellophane is fixed between cylinder body and base, and the trapezoidal inclined plane of above-mentioned sealed Cellophane is with axis
Move up and down.
Further optimization for technique scheme: there is bulge structure on the base of above-mentioned sealed Cellophane, corresponding to above-mentioned
Bulge structure, base has sunk structure.
The slow opening apparatus of electromagnetic valve of the present utility model, fixes due to the column structure of sealed Cellophane and is embedded in the groove of axis
In, the base of above-mentioned sealed Cellophane is fixed between cylinder body and base, and the trapezoidal inclined plane of above-mentioned sealed Cellophane is transported up and down with axis
Dynamic, overcome the defect of original easy permeability of sealing ring fricting movement, meanwhile, there is bulge structure on the base of sealed Cellophane, corresponding
In above-mentioned bulge structure, base having sunk structure, can improve the store oil buffering in oil back chamber, actual tests proves, can improve
Sealed Cellophane service life.What this utility model was creative uses sealed Cellophane to instead of traditional sealing ring, thoroughly overcomes
The inherent shortcoming of existing product permeability, has a good airproof performance, service life length feature.
