Abstract
The invention discloses a high pressure check valve. The high pressure check valve comprises a valve body, a valve closing electromagnet, a valve opening electromagnet and a valve core, wherein a liquid inlet channel and a liquid outlet channel which are located on two sides of the interior of the valve body and transversely extend are arranged in the valve body, the liquid inlet channel is located above the liquid outlet channel, a communication channel which connects the liquid inlet channel with the liquid outlet channel and vertically extends is arranged in the middle of the valve body, a vertical valve core slide rail communicated with the communication channel is arranged above the liquid inlet channel, the valve core is placed in the valve core slide rail, the valve opening electromagnet is arranged at the top of the valve core slide rail, the valve closing electromagnet is arranged on a connection portion of the valve core slide rail and the communication channel, below the liquid inlet channel, and a through hole matched with the bottom end of the valve core is formed in the middle of the valve closing electromagnet. The high pressure check valve is few and simple in element, difficult to damage, simple in internal structure of the valve body, and convenient to process, and reduces time and cost waste caused by frequent replacement and damage of the elements when the number of the elements is large.
Description
?
Technical field
The present invention relates to one-way valve manufacturing technology field, especially a kind of high pressure one-way valve.
Background technique
Active force between conventional high-tension one-way 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 backpressure 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 one-way 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 technological scheme:
A high pressure one-way valve, comprises valve body, closes valve electromagnet, opens valve electromagnet and spool,
At described valve inner, be provided with feed pathway and the liquid outlet channel of the horizontal expansion that is positioned at described valve body both sides, described feed pathway is positioned at described liquid outlet channel top,

Described spool is placed in described spool slideway, on described spool slideway top, opens valve electromagnet described in being provided with, below described feed pathway, described spool slideway and described communicating passage joint be provided with described pass valve electromagnet,
In valve electromagnet neutral position, described pass, be provided with the through hole coordinating with described spool bottom.
Further, in described spool lower side, be provided with half cone-shaped groove, 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 one-way 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.
Accompanying drawing explanation
Cross-sectional schematic when Fig. 1 is the disconnection of a kind of high pressure one-way valve of the present invention oil circuit;
Fig. 2 is the schematic diagram analysed and observe of a kind of high pressure one-way valve of the present invention oil circuit while opening.
Embodiment
Below in conjunction with accompanying drawing, describe the present invention, 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 one-way valve as depicted in figs. 1 and 2, comprises valve body 1, closes valve electromagnet 2, opens valve electromagnet 3 and spool 4,
The feed pathway 11 and the liquid outlet channel 12 that in valve body 1 inside, are provided with the horizontal expansion that is positioned at valve body 1 both sides, feed pathway 11 is positioned at liquid outlet channel 12 tops,
In valve body 1 neutral position, be provided with 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, on spool slideway 14 tops, be provided with out valve electromagnet 3, below feed pathway 11, spool slideway 14 arranges relevant valve electromagnet 2 with communicating passage 13 joints, close valve electromagnet 2 and be all outside outstanding discs of upper and lower two ends
At the neutral position upward and downward that closes valve electromagnet 2 discs, be provided with 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.
In spool 4 lower side, be provided with half cone-shaped groove 41, 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 is used containing the metal of ferro element and makes for material, and valve body 1 itself also can be used 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 is used the not material of metal-containing element to make, a kind of after adopting in the present embodiment.
During use, system pressure oil enters from feed pathway 11, close valve electromagnet 2 and open valve electromagnet 3 and by switch separately, control respectively, open 3 energisings of valve electromagnet, spool 4 moves up under the effect of magnetic force, it is firmly fixed that valve electromagnet solid 3 is opened on top, when 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.In the time of need to again having opened road, only need tube wall to close valve electro-magnet switch 2, open out valve electro-magnet switch 3.
A kind of high pressure one-way 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.
