Description
Technical field
The utility model is related to a kind of flanges.
Background technology
Ring flange, abbreviation flange, the connection of common-use words pipeline respectively fill a flange, on flange in the end point of two pipelines
Centre bore be fluids within pipes channel, two panels flange generally by one circle be bolted.The band mistake occurred currently on the market
The flange for filtering function is to set a raised step surface on flange, filter screen is directly screwed on step surface, although can
Play filtering function, but there are more disadvantages, such as screw to impregnate in a fluid, it is perishable, get rusty, influence consolidating for filter screen
Determine and polluted fluid;The sealing structure of flange is destroyed, and sealing performance is low;It is also inconvenient to replace filter screen;This method simultaneously
When the stubborn bolt of orchid is fixed, nut meeting transfer need to vise nut and twist bolt simultaneously, and the laborious and fixed efficiency of installation is low.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, provides a kind of flange, including ontology, briquetting, filter screen, sealing
Circle and several screws, the ontology are equipped with centre bore and around the circumferentially distributed several bolts hole of centre bore, body upper surfaces
Ring-shaped step a equipped with recess, filter screen are arranged on ring-shaped step a, and the briquetting is annular, the edge of the upper surface of briquetting
Ring-shaped step b equipped with recess, briquetting are pressed on filter screen, and filter screen is secured in a press, the outer ring face of briquetting and ring-shaped step a
Vertical surface fitting, the setting of several screws is connected and fixed briquetting and ontology, the sealing ring embedded rings on ring-shaped step b
It shape step b and is covered on several screws.
The lower surface of the ontology is equipped with several boss, the boss are interior equipped with six correspondingly with several bolts hole
Angular hole.
Preferably, the diameter of the filter screen is less than the outer diameter of briquetting and the internal diameter more than briquetting.
Preferably, the inner ring face of the briquetting and center internal surface of hole flush.
Preferably, the upper surface of the sealing ring is higher by the upper surface of ontology.
Preferably, the upper surface of the sealing ring is higher by the upper surface at least 2mm of ontology.
The utility model has the beneficial effects that:The utility model is novel in design, simple in structure, connection briquetting, filter screen and
The screw of ontology does not impregnate in a fluid, and screw burn into is avoided to get rusty and contaminated-fluid, installation and to replace filter screen also relatively square
Just, the structure design of sealing ring had not only protected screw but also had improved the sealing performance of flange, meanwhile, when twisting bolt, nut is (most often
Nut is six-sided nut) it is stuck in hex hole and can not rotate, bolt then can be directly twisted, when avoiding stubborn bolt
Nut transfer improves the fixed efficiency of installation.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the vertical view of the utility model;
Fig. 3 is the upward view of the utility model.
In figure, 1, ontology, 2, briquetting, 3, filter screen, 4, sealing ring, 5, screw, 6, bolt hole, 7, boss, 8, hexagon
Hole, 9, centre bore.
Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figs. 1-3, the utility model be a kind of flange, if including ontology 1, briquetting 2, filter screen 3, sealing ring 4 and
Dry screw 5, the ontology 1 are equipped with centre bore 9 and around the circumferentially distributed several bolts hole 6 of centre bore 9,1 upper surfaces of ontology
Ring-shaped step a equipped with recess, filter screen 3 are arranged on ring-shaped step a, and the briquetting 2 is annular, the upper surface of briquetting 2
Edge is equipped with the ring-shaped step b of recess, and briquetting 2 is pressed on filter screen 3, the vertical surface in the outer ring face and ring-shaped step a of briquetting 2
Fitting, the setting of several screws 5 are connected and fixed briquetting 2 and ontology 1 on ring-shaped step b, and the sealing ring 4 is embedded in ring-shaped step b
And it is covered on several screws 5.
The lower surface of the ontology 1 be equipped with the one-to-one several boss 7 of several bolts hole 6, in the boss 7
Equipped with hex hole 8.
The diameter of the filter screen 3 is less than the outer diameter of briquetting 2 and the internal diameter more than briquetting 2.
The inner ring face of the briquetting 2 and 9 inner surface of centre bore flush.
The upper surface of the sealing ring 4 is higher by the upper surface 2mm of ontology 1.
The utility model is novel in design, simple in structure, and the screw of connection briquetting, filter screen and ontology is not immersed in fluid
In, it avoids screw burn into from getting rusty and contaminated-fluid, installation and replaces that filter screen is also more convenient, and the structure design of sealing ring was both protected
The sealing performance that screw improves flange again has been protected, meanwhile, when twisting bolt, nut (most common nut is six-sided nut) card
It can not be rotated in hex hole, then can directly twist bolt, nut transfer when avoiding stubborn bolt improves installation and fixes
Efficiency.
Above-mentioned foundation the utility model is enlightenment, and through the above description, relevant staff completely can be not
In the range of deviateing this item utility model technological thought, various changes and amendments are carried out.This item utility model it is technical
Range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
