Detailed description of the invention
In order to overcome foreign material accumulation in pipeline in prior art, cause current disorderly, the problem of the pressure loss, present embodiments provide the through type shown in a kind of Fig. 1 to stretch filter, including housing 1, the top of housing 1 is provided with impurity removal port 2, is provided with impurity removal port cover plate 3 at this impurity removal port 2, is provided with sealing gasket 4 between this impurity removal port cover plate 3 and outboard end of impurity removal port 2；It is provided with screen plate locating slot 5 on the inner surface of impurity removal port cover plate 3, coordinates with the ring-type mounting groove of screen plate 6 being arranged on housing 1 inwall, to realize spacing along the entery and delivery port line direction of housing 1 of the screen plate 7 being arranged in housing 1；The plate face of this screen plate 7 is vertical with entery and delivery port line direction, thus the chamber in housing 1 is divided into filter cup 8 and filter rear chamber 9, and impurity removal port 2 connects with filter cup 8.
When there being foreign material to be deposited in filter cup 8, salvage foreign material can remove foreign material by opening impurity removal port cover plate 3, thus avoid the impact of foreign material heap current.
Wherein, impurity removal port cover plate 3 being offered through hole, the outboard end of impurity removal port 2 offers multiple hoop blind hole, realizes the connection of impurity removal port cover plate 3 and housing 1 by pass through the clamping bolt 21 of the through hole on impurity removal port cover plate 3, blind hole.
In order to current being arranged for laminar condition, the present embodiment is provided with the hexagon filtering holes 10 being evenly arranged shown in multiple Fig. 2 on the plate face of screen plate 7, when current are through certain thickness screen plate 7, the filtering holes 10 of hexagonal shape easily tangles the impurity in current；The hexagon filtering holes 7 being evenly arranged make after screen plate 7 liquid be laminar state；And 2 times that the gross area of hexagon filtering holes 7 is housing 1 water inlet area, water passing capacity is strong.And metal material (such as aluminium alloy, rustless steel etc.) selected by screen plate 7, the impact resistance of screen plate 7 can be improved.
In order to detect water flow pressure, impurity removal port cover plate 3 offers pressure samples hole 11.
As seen from Figure 1, anticreep step 12 it is provided with on the inwall of the water outlet of housing 1, housing 1 water outlet inserts a telescoping tube 13, the inner end inserted in outlet of this telescoping tube 13 connects at least one Anti-off bolt 14, the screw rod of this Anti-off bolt 14 is close on anticreep step 12 so that anticreep step 12 extends between the inner end of telescoping tube 13 and the head of Anti-off bolt 14, telescoping tube 13 so it is possible to prevent to be washed out by current, telescoping tube then can put in along water (flow) direction or stretch out in housing 1, the dislocation of flange bolt installing hole before and after facilitating installation and pipeline can being made up, and then guarantee measuring accuracy.
The water outlet of housing 1 connects a water side flange 15, and this water side flange 15 medial wall arranges the annular seal ring storage tank of a storing sealing ring；Water side flange 15 is inserted into a friction top 16 being set in outside telescoping tube 13, one end inserted in water side flange 15 of this friction top 16 is provided with an annular boss that can embed in annular seal ring storage tank (this annular boss and annular seal ring storage tank matched in clearance), flange axle centered by water (flow) direction in water side so can be made to rotate, be beneficial to make up the dislocation of flange bolt installing hole before and after pipeline.
Friction top 16 is threadeded with water side flange 15 by the fixing bolt 18 of the cover plate 17 through its end, outer end.
The end, outer end of telescoping tube 13 is provided perpendicular to the annular connecting plate 19 of this telescoping tube 13, multiple through hole 20 annularly arranged is offered on this annular connecting plate 19, by this through hole 20, by fixing bolt 18, telescoping tube 13, friction top 16 can be fastened on housing 1 with water side flange 15.
From Figure 2 it can be seen that screen plate 7 is made up of a rectangular portion and a semicircular part, wherein rectangular portion is primarily to adapt to impurity removal port cover plate and design, because the inner surface of impurity removal port cover plate is generally plane.
In sum, it is not difficult to find out, improved through type is stretched filter, by the screen plate that is placed in inner chamber while realizing the filtration to foreign material, making the current after filtering is laminar condition, being beneficial to the maintenance of hydraulic pressure, rotating water side flange is then beneficial to eliminate pipeline and goes forward the dislocation of rear stub bolt hole, improves the accuracy of the water flow pressure in pipeline and metering.
