As shown in Figure 3, be provided with the criss-cross contact component 47 that contacts with the bottom 42 of screen pack 40 at ring 62 structure of an essay.
And for example shown in Figure 5, in relating to the filter S1 of embodiment, be provided with inflow entrance 21 sides that make body 20 and the pipeline 100 of flow export 22 side short circuits in the outside of body 20.In this pipeline 100, be provided with differential valve 105 and flowing detector 101.This differential valve 105 is opened pipeline 100 when the pressure of the fluid of flow export 22 side flow is lower than the pressure of pressure regulation of fluid of inflow entrance 21 side flow, the fluid in the pipeline 100 is flowed; Fluid in these flowing detector 101 signal pipings 100 flows.
As shown in Figure 5, in differential valve 105, be provided with opening 106 and secondary opening 107, be provided with also that big I closing error is pressed spheroid 108 that the metal of an opening 106 of valve 105 forms and usually to the primary side of differential valve 105 elastomer 109 to spheroid 108 reinforcings.Opening 106 a sides formation at differential valve 105 contacts the arc surface 110 that can seal with spheroid 108.
The inside of flowing detector 101 be provided with pipeline 100 in the coaxial spiral helicine color blade (not illustrating) that has of axle of stream.And the window that is used to estimate blade is housed in the side of flowing detector 101.
Be provided with on the stream of this inflow entrance 21 sides at the inlet of inflow entrance 21 sides of pipeline 100 expose, the filter 102 of the tubular thinner than screen pack 40 holes.
In the filter S1 of present embodiment, when screen pack 40 is installed, at first, pull down and cover 24, hold the handle 45 of screen pack 40, screen pack 40 is put into body 20 from access hole 23, be placed on the guide projections 31,32, make open end 41a insert end maintaining part 35.Secondly, moving-member 88 is rotated relative to bar R, make moving-member 88 in an end 81 side shiftings, make a not side direction of prominent bar 91 of moving-member 88 flow export 22 sides, make bar R insert flow export 22 sides, protuberance 82 is inserted recess 80 from bottom 42 sides of screen pack 40.Then, as shown in Figure 6 and Figure 7,, moving-member 88 is rotated relative to bar R, make this prominent bar 91 be positioned at flow export 22 sides with the control lever 90 of moving-member 88 for the prominent bar 91 that makes moving-member 88 can be fixed on the fixed part 95.
Under this state, on the holding section 87 of bar R, engage spanner, simultaneously, push control lever 90, with spanner bar R relative moving part 88 is rotated, make the other end 84 side shiftings of moving-member 88 to bar R.
At this moment, when making them different with bar R, moves moving-member 88, so bar R relative moving part 88 is rotated owing to pushing with the control lever 90 of moving-member 88.
If moving-member 88 is fixed on the fixed part 95, along with bar R relative moving part 88 moves, bar R pushes recess 80 sides, the inwall 30 of body 20 is locked relatively, simultaneously, push recess 80 sides by bar R, taper seat 85a, the 86a of frustum of a cone portion 85,86 slowly presses taper surface 61a, the 61b that is located on the ring 62.At this moment, ring 62 is owing to be fixed on the bottom 42 of screen pack 40, and screen pack 40 is placed on the guide projections 31,32, so not along the moving axially of bar R, and advance to inflow entrance 21 sides along contact-making surface 31a, the 32a of guide projections 31,32.Therefore, as Fig. 1 and shown in Figure 7, the open end 41a of screen pack 40 moves to stage portion 34 directions, and open end 41b closely connects stage portion 34.
At this moment, use fixedly screen pack 40 of bar R, make it not flow side shifting backward, simultaneously, make open end 41b closely connect stage portion 34.Therefore, the gap d between stage portion 34 and the open end 41b does not almost have, and becomes also littler than the mesh of the net 46 of screen pack 40.
In addition, at this moment,, can correctly not insert even do not establish the guiding part of guide bar R compared with the prior art owing in recess 80, only insert protuberance 82 yet.Therefore, can not need guiding part, machining accuracy can be so not high yet, processing become easily, thereby can reduce manufacturing cost.
At this moment, because 31,32 guiding of screen pack 40 usefulness guide projections can not moved reelingly smoothly.Therefore, open end 41b can closely connect stage portion 34 equably.
As the ring 62 of pressing component 60, owing to push with two frustum of a cone portions 85,86 up and down of upside frustum of a cone portion 85 and downside frustum of a cone portion 86, pressing force acts on the screen pack 40 equably.Therefore, can make open end 41b not have close on the bias to stage portion 34.In addition, because ring 62 is located at the bottom 42 of screen pack 40, number of components is few, dismounting easily.
Secondly, will cover 24 and cover access hole 23, be fixed on the body 20 with bolt 26 and nut 26a.
When fluid flowed on the filter S1 of screen pack 40 is housed like this, the foreign matter that is mixed in this fluid filtered away with screen pack 40.At this moment, because the open end 41b of screen pack 40 closely is connected with stage portion 34, d almost very close to each other, fluid almost can not flow in the open end 41b and 34 of the stage portion of screen pack 40, therefore, foreign matter such as dust also almost can not flow in the open end 41b and 34 of the stage portion of screen pack 40.Therefore, nearly all foreign matters such as dust are filtered net 40 collections.Use the thin net of meshes even promptly this means the net 46 of screen pack 40, can not between the open end 41b of screen pack 40 and stage portion 34, escape than the thick foreign matters such as dust of this mesh, also can the thin screen pack 40 of corresponding mesh.Thereby, by selecting the net 46 of screen pack 40, can be from the fluid that flows at stream the separating and filtering foreign matter bigger than desired size.
At this moment, since bottom 42 usefulness contact components, 47 reinforcement of screen pack 40, the situation of 42 crooked expansions bottom can preventing.In addition, though bottom 42 expansions of screen pack 40 also can push with bar R.
Bar R more leans on flow export 22 sides than screen pack 40, but because bar R is thinner, so can not hinder flowing of fluid, fluid can flow through smoothly.And owing to constitute pressing component 60 with ring 62, so can not hinder stream in this, fluid can flow through smoothly.
When fluid flows, if on screen pack 40, filter foreign matter such as dust and accumulate down since fluid on screen pack 40 by becoming difficulty, pressure ratio inflow entrance 21 sides of the fluid of flow export 22 sides are low.At this moment, if the pressure reduction of the fluid of inflow entrance 21 sides and flow export 22 sides surpasses 0.05MPa, then the elastic force of the fluid of inflow entrance 21 sides opposing elastomer 109 and press off the spheroid 108 of valve for pressure difference 105 flows fluid, and makes the blade rotation of flowing detector 101 in pipeline 100.
Thus, owing to during flowing detector 101 test fluid mobile, can grasp the situation that screen pack 40 is in blocked state, so, just can understand the scavenging period of screen pack 40 and replacing time and unusually as long as make regular check on flowing detector 101.This situation is owing to open and close pipeline 100 with valve for pressure difference 105, and reactivity is good, can hold flow regime reliably.
In addition, since the inlet of inflow entrance 21 sides of pipeline 100 be provided with stream in inflow entrance 21 sides expose, identical with the hole of screen pack 40 or than its thinner filter 102, even event is at the thin net of online use of the net 46 of screen pack 40, can not escape than the foreign matters such as dust that this mesh is thick by pipeline 100 yet, also can the thin screen pack 40 of corresponding mesh.In addition, because filter 102 exposes at the stream of inflow entrance 21 sides, so the fluid that flows in stream often is exposed, therefore, the often the filter rinsed 102 because foreign matter that filter 102 captures flows also is so maintenance easily.
Secondly, remain on the screen pack 40 at foreign matters such as dusts, clean or when changing this screen pack 40, stop direction of flow filter S1 temporarily, take off and cover 24, on the holding section 87 of bar R, engage spanner, bar R relative moving part 88 is rotated, make moving-member 88 to an end 81 side shiftings, the locking of the relative body 20 of relieving rod R, simultaneously, rotation control rod 90 makes prominent bar 91 towards inflow entrance 21 sides.Also can make moving-member 88 and bar R move simultaneously this moment, pulls down prominent bar 91 from fixed part 95.Afterwards, take out bar R, simultaneously, control handle 45, pull down screen pack 40 from body 20.
At this moment because moving-member 88 pulls down with bar R, so on the pin thread 83 of the negative thread 89 of moving-member 88 and bar R not the fluid by screen pack 40 be difficult to tangle.Therefore, the foreign matters such as dust that are mixed in this fluid are difficult to enter between negative thread 89 and the pin thread 83, when being installed to screen pack 40 on the body 20 below, be difficult to cause interlock between negative thread 89 and the pin thread 83, the rotation of bar R relative moving part 88 can be carried out reliably, the function of press device P can be brought into play conscientiously.
In addition, even this moment hypothesis has entered foreign matters such as dust in recess 80 because protuberance 82 is to the inserted mode of recess 80, below with screen pack 40 when body 20 is installed, also can prevent the state of affairs that stopping bar R nips.In this, bar R is the rotation of relative moving part 88 reliably also, can reliably bring into play the function of press device P.
In addition, when between the pin thread 83 of the negative thread 89 of moving-member 88 and bar R, having foreign matters such as dust, the foreign matter just in case nip, when bar R relative moving part 88 can not be rotated, with the spanner that is fastened on the holding section 87 moving-member 88 is moved simultaneously, bar R is rotated, pull down prominent bar 91, make the not part of prominent bar 91 of moving-member 88 take off bar R towards fixed part 95 from fixed part 95.Therefore, compared with the prior art, even nip foreign matter between negative thread 89 and pin thread 83, also can pull down bar R, not change filter S1 integral body, only changing bar R can complete repairs.
In addition, pull down screen pack 40 owing to can hold handle 45 this moment, carries out operation easily.
After this, cleaning screen pack 40 or more renew is installed screen pack 40 as mentioned above.
The filter S2 of another embodiment of expression the present invention in Fig. 8 and Figure 10.The filter S2 of this another embodiment is roughly identical with above-mentioned formation, but pressing component 60 is different with the formation of above-mentioned embodiment filter.As Fig. 8 to shown in Figure 10, this pressing component 60 have than bar R diameter big inserting hole 64, by forming with the framework 65 that screen pack 40 bottoms touch.Framework 65 is formed by metal, and the bottom of face and screen pack 40 touches, and forms rectangular box-like that a pair of vertical post 66 and spreader 67 form is housed respectively.
Inserting hole 64 is located at the central authorities of spreader 67 respectively.On the opening edge of inserting hole 64, form cone shape taper surface 61a, the 61b of taper seat 85a, 86a that contact is located at a pair of frustum of a cone portion 85,86 of bar R.
Other structure is with above-mentioned the same.
Thereby, when on this filter S2, screen pack 40 being installed, as shown in figure 10, pressing component 60 is shifted to flow export 22 sides makes inserting hole 64 and bar R be offset e in the drawings, enlarge the interval of pressing component 60 and end maintaining part 35, at this state, on the guide projections 31,32 of filter S2, place screen pack 40.Then, the protuberance 82 of the bar R of the inserting hole 64 that inserts pressing component 60 is inserted recess 80.Then, moving-member 88 is rotated relative to bar R, make prominent bar 91 towards fixed part 95 sides.Then, bar R relative moving part 88 is rotated, make moving-member 88 shift to the other end 84 sides of bar R.
At this moment, as long as the prominent bar 91 of moving-member 88 is fixed on the fixed part 95, bar R is by pressing to recess 80 sides, and the inwall 30 of body 20 is locked relatively.Afterwards, bar R is to recess 80 side shiftings, and taper surface 61a, the 61b of lower frame body 65 presses in frustum of a cone portion 85,86, makes this pressing component 60 to inflow entrance 21 side shiftings.Therefore, the open end 41b of screen pack 40 closely is connected with stage portion 34.The whole face of touching that can be used as the framework 65 of pressing component 60 this moment carries out pushing of screen pack 40, can push screen pack 40 more equably, can eliminate the gap d that produces on stage portion 34 and open end 41b.Other effect, effect are with above-mentioned identical.
In addition, the switch of circuit places the sensor of ON to constitute flowing detector 101 in the time of also can adopting the fluid of pipeline 100 to flow, and might as well suitably change.
