Specific implementation mode
The utility model is further described with reference to specific embodiment：
A kind of fore filter as shown in Figure 1 and Figure 4, including cylinder 1 are provided with filter assemblies, the cylinder in cylinder 1
1 upper end of body is bolted with cover 2, and 2 both sides of cover offer inlet opening 3 and apopore 4 in opposite directions；The filter assemblies include hollow
Filtration core 5 is provided with filter screen 6 on filtration core 5, and 2 bottom of the cylinder is connected with ball valve 7, and 7 lower end of ball valve is provided with sewage draining exit
8；The material of the cover 2 is stainless steel；5 upper end of the filtration core is provided with limit protrusion 15, the setting of 1 opening of the cylinder
There is limiting groove compatible with the limit protrusion 15 16.For user when using fore filter, fluid is from 2 side of cover
Inlet opening 3 flows into, and water flows into cylinder 1, and in the power by hydraulic pressure, water is inwardly flowed to the filter screen 6 outside filtration core 5
Enter, by the water of filtering, finally apopore 4 of the unicom on cover flows out along filter assemblies, the impurity filtered in water due to
Gravity, and strainer 6 can not be penetrated, the sewage draining exit 8 that setting is finally pierced by 1 lower end of cylinder flows out.It is noted that institute
The cover 2 stated is made using stainless steel or metal material, for the preposition mistake provided to the city of cold district
Filter can provide stronger intensity, improve the fore filter working efficiency.And filtration core 5 in fore filter in order to prevent
It will not shake back and forth, the limit protrusion 15 of setting and matched limiting groove 16 provide very to fix the component
Big guarantee.
As shown in Fig. 2, this practicality is further arranged to, the cylinder 1 is to be threadedly coupled with the connection type of cover 2, institute
The external screw thread lower end for stating cylinder 1 is evenly equipped with several reinforcing ribs 9.Due to the design that fore filter cylinder 1 is cylinder, in installation
In the process, the phenomenon that presence that may touch water makes it when by being threadedly coupled, causes landing that can not screw, thus
The reinforcing rib 9 added makes user during the installation process, increases the friction area of hand and cylinder 1, its installation is made more to fasten.
The utility model is further arranged to, and the cylinder 1 is made of transparent plastic material.In the utility model
Cylinder 1 uses transparent plastic material, be on the one hand facilitate user observe in time impurity in cylinder content number, side
Just user clears up in time；Another aspect plastic material cost is low, the less waste of material.
As shown in figure 3, the utility model is further arranged to, 5 upper end of the filtration core is evenly equipped with several intake chambers 10.By
Effective filtration treatment can be carried out to water in filter screen 6, but large granular impurity once occur, then large particle can occur and scrape
Bad filter screen 6, the intake chamber 10 that ring is set, blocks most large granular impurities, to preferably protect the filtering in cylinder 1
Component.
As shown in Fig. 2, the utility model is further arranged to, lower end is evenly equipped with several guide pins 11 in the cylinder 1.By
In contamination precipitation, the intensity requirement of increasing can be had to lower end in cylinder 1, several guide pins 11 added can not only add
The intensity of lower end in strong cylinder 1, while the effect of drainage can be played to impurity, prevent the blocking of impurity in cylinder 1.
The utility model is further arranged to, and the ball valve 7 is to be threadedly coupled with the connection type of cylinder 1, the ball valve 7
It is threadedly coupled the face to offset with cylinder 1 and is equipped with O-ring seal.In order to ensure the leakproofness of whole fore filter, in ball valve 7
The position being connected with each other between cylinder 1, the O-ring seal of setting, the sealing intensity that O-ring seal is provided make this practicality
It is novel during blowdown will not there is a phenomenon where sewage from gap expose.O-ring seal simultaneously, also in installation process
What the ball valve 7 of bottom more fastened is fixed on cylinder.
As shown in Figure 1, the utility model is further arranged to, the activity that control ball valve 7 is opened and closed is provided on the ball valve
Limiting slot at spanner, and the two of restriction monkey wrench motion range.The ball valve 7 is carried out by monkey wrench 13 to sewage draining exit
8 opening and closing, screw thread, is not arranged the monkey wrench 13 on sewage draining exit 8 due to strength is excessive and made by monkey wrench 13 in order to prevent
At the serious consequence of sliding tooth, limiting slot 7 at two on ball valve 7 is set, effectively prevents above-mentioned phenomenon and occurs.
The utility model is further arranged to, and the ball valve 7 is to be threadedly coupled with the connection type of cylinder 1, the ball valve 7
O sealing rings are provided at screw thread.Ball valve 7 is connect with cylinder 1 relies on internal and external threads, adds O-ring seal therebetween, is
Under the premise of the bonding strength of fastening between the two, the leakproofness of entire fore filter is also improved.
As shown in Figure 1, the filter assemblies further include having the filter holder 14 being arranged on filter screen 6.In order to better
The use for protecting the components such as self-filtering core, in its outer filter holder 14 being arranged with, the component for supporting it internal, make its compared with
Flood pressure will not shake back and forth, and ensure its filter effect.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
