Cylinder and film, below cylinder, the cylinder is arranged outside valve body the thin-film covering, and the film is arranged in fluid channel
In.
Preferably, retainer plate and compacting ring are provided with outside the filter screen, the retainer plate is fixed in valve body,
Filter screen is pressed in retainer plate by the compacting ring.
Preferably, the retainer plate is U-typed, and retainer plate top two sides are provided with through-hole, and running through in the through-hole has
Screwing screw.
Preferably, the retainer plate inner surface is equipped with rubber skin.
Preferably, the filter screen is circle.
Preferably, the area of the filter screen is greater than the area of retainer plate.
The utility model has the advantages that compared with prior art
(1) the utility model is provided with retainer plate, filter screen and compacting ring, and filter screen is clamped in by retainer plate and compacting ring
Centre, the effect that can efficiently complete filtering can be replaced easily additionally by the setting of retainer plate, compacting ring and hole
Strainer ensure that the normal work of valve, and structure is simple, at low cost.
(2) the utility model is provided with pneumatic device, can apply to fluid and press when valve inner is provided with filter screen
Power guarantees the proper flow of fluid, improves work efficiency.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The utility model discloses a kind of hydraulic control one-way valves, as shown in Figure 1, including valve body 1 and spool 2, the side of valve body 1
It is provided with oil inlet 3, the bottom end of valve body 1 is provided with oil outlet 4, fluid channel 5, valve are provided between oil inlet 3 and oil outlet 4
Core 2 is horizontally installed on 4 top of oil outlet, and spool 2 is oppositely arranged with oil inlet 3, when the pressure that the fluid of oil inlet 3 generates is enough
When big, push spool 2 to side, opens fluid channel 5, fluid circulation.The top of fluid channel 5 offers a hole, in hole
It is vertically installed with filter screen 62, sealing cover 7 is provided with above hole, retainer plate 61 and compacting ring is provided with outside filter screen 62
63, retainer plate 61 is fixed in valve body 1, and filter screen 62 is pressed in retainer plate 61 by compacting ring 63.As shown in Fig. 2, solid
Surely circle 61 is U-typed, and 61 top two sides of retainer plate are provided with through-hole, and through there is a screwing screw 8 in through-hole, retainer plate 61 can be with
The top of retainer plate 61 is tightened by screw means.61 inner surface of retainer plate is equipped with rubber skin, can not only guarantee to seal
Property, it can also be ensured that retainer plate 61 and compacting ring 63 are non-slip when agreeing with.Preferably, the filter screen 62 in the utility model is circle
Shape, and the area of filter screen 62 is greater than the area of retainer plate 61.It further, further include pneumatic device in the utility model, it should
Pneumatic device includes cylinder 9 and film 10, and film 10 is sleeved on 9 lower section of cylinder, and cylinder 9 is arranged outside valve body 1, and film 10 is set
It sets in fluid channel 5, during fluid flowing, starts pneumatic device, by gassy in film 10,10 convection current of film
Body is squeezed, and is allowed fluid to move quickly through filter screen 62, is guaranteed the proper flow of fluid, wherein the film 10 is filling
Volume when full gas is less than the half of 5 vertical cross-section volume of fluid channel, therefore will not block fluid channel 5.
Working principle: when the pressure that the fluid of oil inlet 3 generates is sufficiently large, pushes spool 2 to side, it is logical to open fluid
Road 5, fluid circulation.Pass through filter screen 62 when fluid flows, impurity is filtered, impurity is prevented further to be deposited in spool 2
Place, influences the normal work of spool 2, when needing replacing strainer, sealing cover 7 is opened, by the screwing screw 8 of 61 upper end of retainer plate
It reversely rotates, loosens retainer plate 61, filter screen 62 and compression net are taken out, replacement filter screen 62 is carried out, by new mistake
Strainer 62 is placed between retainer plate 61 and compacting ring 63, is screwed retainer plate 61 by screwing screw 8 so that compacting ring 63 with
Retainer plate 61 agrees with completely, covers sealing cover 7, and valve body 1 can be used normally.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
