Abstract
The utility model discloses a check valve that has the filter screen, including input port, delivery outlet, filter screen, valve clack and leakage -proof cover. The cross section of check valve be that a square and one are circular, circular circumscribed in the square. The filter screen splice to become by the different filter screen of two pore sizes. The aperture of first filter screen is greater than the aperture of second filter screen, first filter screen install and be close to one side of input port, the second filter screen install and be close to one side of delivery outlet. Impurity in filter screen accumulative total will during to a ration the leakage -proof cover open, will the filter screen take out and clean up install into again. The utility model provides a check valve, simple structure, can be convenient take out and clear up filter screen, convenient to use.
Description
Technical field
This utility model relates to a kind of check valve, is mainly used on farm machinery。
Background technology
Along with the progressively development of automatization, the automaticity of farm machinery is also more and more higher, and the use of hydraulic control system is also more extensive。But being the groundwork of farm machinery soil, the impurity that long work can cause in hydraulic control system in hydraulic oil increases, and affects the work of whole hydraulic control system。
Existing check valve with drainage screen be also single wire side, it does not have impurity deposition space；Or impurity deposition space is little, after impurity deposition, it is not easy cleaning。
Summary of the invention
In order to overcome disadvantages mentioned above, this utility model provides with a kind of check valve with detachable strainer, including input port, delivery outlet, flap, filter screen and leakage-proof cover；Described check valve cross section is foursquare；Described filter screen is arranged in the middle of described input port and delivery outlet, through the hole wall of described check valve；The length of described filter screen is equal to the length of side of the cross section of described check valve；Described flap is arranged between described filter screen and described input port；By the filter screen that two kinds of apertures are different on described filter screen: the first filter screen and the splicing of the second filter screen；The aperture of the first described filter screen is more than the aperture of the second described filter screen；The first described filter screen is arranged close to the side of described input port；The second described filter screen is arranged close to the side of described delivery outlet；Described filter screen is dismountable。
Further, described filter screen has a leakage-proof cover；Described leakage-proof cover has one layer of sealing ring；The side of described leakage-proof cover is connected by loose-leaf with described check valve；The opposite side of described leakage-proof cover is connected by latch with described check valve。
The check valve with detachable strainer that this utility model provides, filter screen is dismountable, in that context it may be convenient to cleaning impurity and circulation practicality；Simple in construction, easy to install and use, it is not necessary to professional person, easy to maintenance；Filter screen has leakage-proof cover, it is possible to effectively prevent liquid from leaking；The described sealing ring on leakage-proof cover can be changed, and extends the service life of check valve。
Accompanying drawing explanation
Fig. 1 is the sectional view of the check valve that this utility model provides。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details。
As it is shown in figure 1, the check valve with detachable strainer that this utility model provides, including input port 101, delivery outlet 102, filter screen 103, flap 104 and leakage-proof cover 105。The cross section of described input port 101 and described delivery outlet 102 is circular, has screw thread above, is conveniently connected with miscellaneous part。The cross section of described check valve is that four sides is foursquare, and there is the equal diameters of a circular hole, the diameter in described hole and described filter screen 103 side of described check valve；The length of described filter screen 103 and the equal diameters of described check valve。Described filter screen 103 is arranged in described check valve by described hole, in the centre of described input port 101 and described delivery outlet 102。Described flap 104 is arranged on the centre of described described filter screen 103 and described input port 101。
Described filter screen 103 has different the first filter screen 113 of two pore sizes and the second filter screen 123 to be spliced into。The aperture of the first described filter screen 113 is more than the aperture of the second described filter screen 123。The first described filter screen 113 is arranged close to the side of described input port 101, and the second described filter screen 123 is arranged on the side of described input port 102。Varying in size of first filter screen 113 of both sides and the aperture of the second filter screen 123, it is possible to impurity is stayed in described filter screen 103。
Described filter screen 103 has leakage-proof cover 105, described leakage-proof cover has sealing ring 115, it is possible to prevent liquid from leaking。The side of described leakage-proof cover 105 is connected by loose-leaf 106 with described check valve, and opposite side is connected by latch 107 with described check valve。In use, described leakage-proof cover 105 is covered, described latch 107 is plugged。When impurity machinery to certain degree, described leakage-proof cover 105 is opened, described filter screen 103 is taken out, places into after cleaning up in described check valve。
These are only this utility model preferred embodiment, therefore can not limit the scope that this utility model is implemented according to this, the equivalence namely made according to this utility model description changes and decoration, all should belong in the scope that this utility model covers。
