The technical solution of the utility model embodiment is explained with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the embodiment in embodiment,
Those skilled in the art obtain other embodiment under the premise of creative work is not made, and belong to the utility model
Protection domain.
In the following description, occur the indicating positions such as term " interior ", " outer ", " on ", " under ", "left", "right" or
Position relationship is based on orientation shown in the drawings or position relationship, and description embodiment merely for convenience is described with simplified, and
It is not instruction or implies signified device or element there must be specific orientation, with specific azimuth configuration and operation, because
This is it is not intended that limitation to the utility model.
Embodiment one：
As shown in Figure 1, the present embodiment is a kind of check valve assembly, including valve deck 1, the valve deck 1 is equipped with for media flow
The first logical recirculation hole 11, the valve deck 1 are equipped with the elastic valve plate 12 for closing first recirculation hole 11, the medium
When flowing to elastic valve plate 12 towards circulating direction, the elastic valve plate 12 is rushed to open to open first recirculation hole 11, described
Valve deck 1 is equipped with the catch 13 for limiting 12 maximum open position of elastic valve plate, and the catch 13 is integrally formed with valve deck 1.
In the present embodiment, catch 13 is provided on valve deck 1, catch 13 is the maximum open position progress to elastic valve plate 12
Limiting, after elastic valve plate 12 is impacted by medium to be opened, elastic valve plate 12 can be washed open gradually, until after offseting with catch 13,
Elastic valve plate 12 does not continue to open, and after setting the catch 13, can effectively limit the maximum deformation quantity of elastic valve plate 12, so as to
Elastic valve plate 12 can be reduced to a certain extent beyond its maximum deformation quantity, and even after long-term work, elastic valve plate 12 is still
Initial position can be restored to.
In addition, the catch 13 in the present embodiment is to be integrally formed with valve deck 1, this causes operating personnel practical in assembling process
In, without being assembled to catch 13 and valve deck 1, by mold straight forming, reduce assembly time, simultaneously because catch 13 with
Valve deck 1 is to be integrally formed, and fixation between the two do not need to fastening screw etc., and also avoid that fastening screw easily loosens asks
Topic ensures that the position relationship between catch 13 and valve deck 1 also keeps relative stability under long-term work.
Concrete structure：
Catch 13 in the present embodiment is inclined on the valve deck 1, also can be found in shown in Fig. 2 and Fig. 3, the bullet
Property valve block 12 be located between 13 and first recirculation hole 11 of catch, the first recirculation hole 11 in the present embodiment be located at valve deck 1 center
At position, elastic valve plate 12 rotates after being rushed to open relative to the valve deck 1.When being that elastic valve plate 12 is not rushed to open in Fig. 2
Schematic diagram, and in Fig. 3 be then the schematic diagram after elastic valve plate 12 is rushed to open.
It is planar structure that elastic valve plate 12, which is rushed to open part, in the present embodiment, and catch 13 is also planar structure, when described
After elastic valve plate 12 is washed open completely, the plane of the plane of elastic valve plate 12 just with the catch 13 is bonded, so as to prevent
Elastic valve plate 12 is abnormal deformation.It should be noted that fitting referred herein, does not need to be bonded completely, as long as ensureing
Basic fitting, because build-up tolerance reason, manufacturing tolerance etc. accomplish that the probability being bonded completely is smaller.
Between 10 °~50 °, angle of inclination is excessive, then leads at angle of inclination in the present embodiment between catch 13 and valve deck 1
Causing the angle that elastic valve plate 12 is rushed to open also can accordingly become larger, and be easy to cause 12 excessive deformation of elastic valve plate, it is difficult to be restored to just
Beginning position, and angle of inclination is too small, then also results in the problem of circulation is not smooth, it is usually preferred to it is 30 °.
The mounting means of elastic valve plate 12 in the present embodiment is to be installed by way of clamping, described in the present embodiment
Valve deck 1 includes outer cover 1A and inner cover 1B, and the elastic valve plate 12 is installed between outer cover 1A and inner cover 1B, and the catch 13 is set
On the outer cover 1A, the mode of outer cover 1A and inner cover 1B clampings, ease of assembly are utilized.It should be noted that in other implementations
In mode, it is not limited to which this mounting means, the design of those skilled in the art through this embodiment are readily apparent that in valve deck 1
One slot of upper setting, allows elastic valve plate 12 to insert in slot, can also realize the installation of elastic valve plate 12, this embodiment
It also falls into the scope of protection of the utility model.
In the present embodiment, on valve deck 1 other than the first recirculation hole 11, the second recirculation hole 14 is also provided with, second is set
Two check valve assemblies can be cooperated use by the purpose of through-hole 14, a valve body to two-way circulate be formed, specifically under
Text is illustrated.
Embodiment two
As shown in Figures 2 and 3, the present embodiment is a kind of device for drying and filtering, and including filter cylinder 2,2 both ends of filter cylinder are equipped with end cap 6,
The both ends of the filter cylinder 2 are respectively equipped with inlet pipe 3 and outlet pipe 4, and inlet pipe 3 and outlet pipe 4 are connected on two end caps 6 of filter cylinder, described
It is equipped with filter core 5 in filter cylinder 2, both ends at least one end of the filter core 5 is equipped with check valve assembly, in the present embodiment, is preferably filtering
The both ends of core 5 are equipped with such as the check valve assembly in embodiment 1, the two check valve assemblies combine after use, actually
Form a valve body to two-way circulate.
By taking Fig. 3 as an example, when medium from the right side turn left circulation when, medium from the second recirculation hole 14 in right one-way valve module into
Enter, after the filtering of filter core 5, flowed out from the first recirculation hole 11 in left side check valve component；When medium circulates from left to right,
The second recirculation hole 14 enters in total left side check valve component, from the first circulation of right one-way valve module after the filtering of filter core 5
It is flowed out in hole 11.
Need what is illustrated, be in the present embodiment 5 both ends of filter core all using the check valve assembly in embodiment 1, in other realities
It applies in mode, the check valve assembly in only can setting embodiment 1 in one end of filter core 5, the other end can be used common unidirectional
