Description
Technical field
It the utility model is related to mechanical field, and in particular to automatic reverse check valve.
Background technology
Check valve is commonly used valve in hydraulic drive, and it can make fluid only one-way flow, prevent opposite direction from flowing.It is existing
Check valve of today can only make one-directional fluid flow, but with the development of science and technology, be needed when having many automation equipment work
The one-way flow of positive direction, it is also desirable to the one-way flow of opposite direction.
The content of the invention
The defects of the purpose of this utility model exists aiming at prior art, there is provided one kind can be unidirectional with automatic reverse
Valve.
Its technical scheme is：Automatic reverse check valve, including valve body, described valve body include the first valve pocket and the second valve
Chamber, the first described valve pocket are provided with the first valve element, and the second described valve pocket is provided with the second valve element, the first described valve pocket with
Moveable block body is provided between second valve pocket, described block body is located at top, the action that the first valve pocket passes through the first valve element
Communicated with the second valve pocket；Described block body is located at bottom, and the second valve pocket is communicated by the action of the second valve element with the first valve pocket；Institute
The valve body stated is provided with through hole, and described block body is provided with valve rod, and described valve rod is interspersed in through-holes, described through hole and valve
Sealing mechanism is provided between bar, magnetic valve is installed on described valve rod.
Further preferably, the first described valve element includes baffle plate, spring, fixed plate, flange, and one end of described baffle plate is set
Have rod member, spring be installed on described rod member, described spring supporting in fixed plate and the centre of baffle plate, the baffle plate it is another
One end is spacing by flange.
Further preferably, described fixed plate is provided with multiple through holes.
Further preferably, described baffle plate is cone.
The utility model compared with prior art, has advantages below：Reasonable in design, simple in construction, reliable in action, energy
The one-way flow of the automatic positive and negative direction of fluid is realized, it is practical.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model positive direction work.
Fig. 2 is the structure chart of the utility model opposite direction work.
1, valve body 2 in figure, the first valve pocket 3, the second valve pocket 4, magnetic valve 5, valve rod 6, sealing mechanism 7, block body 8,
Baffle plate 9, spring 10, fixed plate 11, rod member 12, flange 13, the first valve element 14, the second valve element.
Embodiment
Reference picture 1, Fig. 2, automatic reverse check valve, including valve body 1, valve body 1 include the first valve pocket 2 and the second valve pocket 3, the
One valve pocket 2 is provided with the first valve element 13, and the second valve pocket 3 is provided with the second valve element 14, set between the first valve pocket 2 and the second valve pocket 3
Moveable block body 7 is equipped with, when block body 7 is located at top, action and second valve pocket 3 of first valve pocket 2 by the first valve element 13
Communicate, magnetic valve 4 is installed on described valve rod；When block body 7 is located at bottom, the second valve pocket 3 passes through the dynamic of the second valve element 14
Work communicates with the first valve pocket 2；Valve body 1 is provided with through hole, and block body is provided with valve rod 5, and valve rod 5 is interspersed in through-holes, through hole and valve
Sealing mechanism 6 is provided between bar 5；First valve element 13 includes baffle plate 8, spring 9, fixed plate 10, flange 12, the baffle plate 8
One end is provided with rod member 11, and spring 9 is provided with described rod member 11, and spring 9 is supported on the centre of fixed plate 10 and baffle plate 8, institute
It is spacing by flange 12 to state the other end of baffle plate 8, the second valve element 3 is identical with the structure of the first valve element 2；Fixed plate 10 is provided with multiple logical
Hole；Baffle plate 8 is cone.
In use, when magnetic valve powers off, least significant end is moved on to by the active force valve body of magnetic valve inner spring, fluid can only be through
The second valve element 14 is crossed, opens baffle plate top by the pressure of fluid, fluid flows into the first valve pocket 2 by the through hole in fixed plate, then
Outflow.Because block body 7 blocks the first valve element 13 during fluid opposite direction, the second valve pocket 3 can not be flowed into, the second valve element by baffle plate with it is convex
The effect of edge, it can not also flow into the second valve pocket 3.
During solenoid valves, top in figure is moved on to by the magnetic force valve rod linkage valve of electromagnet, fluid can only pass through
First valve element 13, the top of baffle plate 8 is opened by the pressure of fluid, fluid flows into the second valve pocket 3 by the through hole in fixed plate 12, then
Outflow.Because block body 7 blocks the second valve element 14 during fluid opposite direction, the first valve pocket 2 can not be flowed into, the second valve element by baffle plate 8 with
The effect of flange 12, the first valve pocket 2 can not be also flowed into,
Above-described is only preferred embodiment of the present utility model, it is impossible to limits the model of the utility model implementation
Enclose, every equivalent change made according to present utility model application the scope of the claims and decoration, should all still fall within the utility model and cover
In the range of.
