Description
Technical field
The present invention relates to check valve manufacturing technology field, especially a kind of high pressure check valve.
Background technology
Active force between conventional high-tension check valve utilization machinery original paper is realized the switch of oil circuit, piston and inner ball valve are set conventionally and realize the switch of oil circuit, piston advances by pressure oil, and reset by spring or buffer brake oil, structure complex structure, valve body difficulty of processing is high, and how fragile joint is.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high pressure check valve, original paper is few and simply not fragile, reduces and has the more frequent replacing causing of original paper to damage time and cost waste that original paper causes, and valve body inner structure is simply easy to process.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of high pressure check valve, comprises valve body, closes valve electromagnet, opens valve electromagnet and spool,
Be provided with the laterally extending feed pathway and the liquid outlet channel that are positioned at described valve body both sides at described valve inner, described feed pathway is positioned at described liquid outlet channel top,
Be provided with in described valve body centre position and connect described feed pathway and described liquid outlet channel, vertical communicating passage of extending, above described feed pathway, be provided with spool slideway vertical, that be communicated with described communicating passage,
Described spool is placed in described spool slideway, opens valve electromagnet on described spool slideway top described in being provided with, below described feed pathway, described spool slideway and described communicating passage junction be provided with described pass valve electromagnet,
Be provided with in valve electromagnet centre position, described pass the through hole coordinating with described spool bottom.
Further, be provided with half cone-shaped groove in described spool lower side, when this conical recess coordinates with through hole on the valve electromagnet of described pass in described spool bottom, corresponding with described feed pathway position.
A kind of high pressure check valve of the present invention, original paper is few and simply not fragile, reduces and has the more frequent replacing causing of original paper to damage time and cost waste that original paper causes, and valve body inner structure is simply easy to process.
Brief description of the drawings
Cross-sectional schematic when Fig. 1 is the disconnection of a kind of high pressure check valve of the present invention oil circuit;
Fig. 2 is the schematic diagram analysed and observe of a kind of high pressure check valve of the present invention oil circuit while opening.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of high pressure check valve as depicted in figs. 1 and 2, comprises valve body 1, closes valve electromagnet 2, opens valve electromagnet 3 and spool 4,
Be provided with the laterally extending feed pathway 11 and the liquid outlet channel 12 that are positioned at valve body 1 both sides in valve body 1 inside, feed pathway 11 is positioned at liquid outlet channel 12 tops,
Be provided with in valve body 1 centre position and connect feed pathway 11 and liquid outlet channel 12, vertical communicating passage 13 of extending, above feed pathway 11, be provided with spool slideway 14 vertical, that be communicated with communicating passage 13,
Spool 4 is placed in spool slideway 14, its diameter is corresponding with spool slideway 14 internal diameters, the length of spool 4 is less than the length of spool slideway 14, be provided with out valve electromagnet 3 on spool slideway 14 tops, below feed pathway 11, spool slideway 14 arranges relevant valve electromagnet 2 with communicating passage 13 junctions, close valve electromagnet 2 and be all outside outstanding discs of upper and lower two ends
Be provided with at the centre position upward and downward that closes valve electromagnet 2 discs the through hole 21 coordinating with spool 4 bottoms, spool 4 bottoms are conical, and through hole 21 first halves are inverted round table shape hole.
Be provided with half cone-shaped groove 41 in spool 4 lower side, corresponding with feed pathway 11 positions when this conical recess coordinates with through hole 21 on the valve electromagnet 2 of pass in spool 4 bottoms.
Spool of the present invention 4 uses containing the metal of ferro element and makes for material, and valve body 1 itself also can use the material with ferro element, opening valve electromagnet 3, close between valve electromagnet 2 and spool 4 and valve body 1 setting every magnetosphere; Or valve body 1 itself uses the not material of containing metal element to make, a kind of after adopting in the present embodiment.
When use, system pressure oil enters from feed pathway 11, close valve electromagnet 2 and open valve electromagnet 3 respectively by switch control separately, opening valve electromagnet 3 switches on, spool 4 moves up under the effect of magnetic force, it is firmly fixed that valve electromagnet solid 3 is opened on top, in the time that needs disconnect oil circuit, close the switch of make and break valve electromagnet 3, make switch valve electromagnet 2 switches, spool 4 moves down, and is closing under the magnetic force of valve electromagnet 2 and the pressure-acting of double cone-shaped groove of pressure oil 41, and the conical bottom of spool 4 is firmly fixed in through hole 21. Need to again open road time, only need tube wall to close valve electro-magnet switch 2, open out valve electro-magnet switch 3.
A kind of high pressure check valve of the present invention, original paper is few and simply not fragile, reduces and has the more frequent replacing causing of original paper to damage time and cost waste that original paper causes, and valve body inner structure is simply easy to process.
