Abstract
The utility model discloses a kind of monoblock types to expand bayonet drain cap, filter including intermediate plate, positioned at intermediate plate upper end and the expansion bayonet positioned at intermediate plate lower end, the filter, intermediate plate and expansion bayonet three are the monoblock type that links together, the expansion bayonet can be installed in the filtration hole of porous plate, and the drain cap of the utility model is simple in structure, is readily produced, will not be loosened in easy for installation and operational process.
Description
Technical field
The utility model is related to water-treatment technology fields, and in particular to a kind of monoblock type expansion bayonet drain cap.
Background technology
The structure of existing drain cap is split type, filter mostly（Band connection handle）Adduction cap, when water cap be inserted into it is more
In the filter opening of orifice plate, from the lower part of water filter plate, nutting is fixed on drain cap porous then by nut check at external screw thread
On plate.Nut must be screwed on this mode from the lower part of porous plate when mounted, in some spaces than narrow place, just without
Method is operated, in addition this water cap easy loose or dislocation in the process of running.
Invention content
The purpose of this utility model is to solve the defect of existing split type drain cap, provides a kind of monoblock type expansion bayonet row
Water cap, the drain cap is simple in structure, is readily produced, will not be loosened in easy for installation and operational process.
Realize that the technical solution of the utility model aim is：A kind of monoblock type expansion bayonet drain cap, including centre
Plate, the filter positioned at intermediate plate upper end and the expansion bayonet positioned at intermediate plate lower end, the filter, intermediate plate and expansion bayonet three
Person is the monoblock type that links together, and the expansion bayonet can be installed in the filtration hole of porous plate, wherein the filter, in
Between plate and expansion bayonet three be link together monoblock type refer to three connect fasten by way of for example be glued, weld
It connects, be threadedly coupled etc. and being formed as monoblock type.
Further, the expansion bayonet top half is cylinder, and the expansion bayonet lower half portion is inversed taper platform shape.
Further, the diameter d of the cylinder is less than the diameter D of the filtration hole, the upper surface of the inversed taper platform shape
Diameter is more than the diameter D of the filtration hole so that expanding the inversed taper platform shape part of bayonet can clamp after the filtration hole
On porous plate.
Further, the centre of the cylinder is provided with the through-hole of a diameter of d1, the centre of the inversed taper platform shape in an axial direction
It is provided with a diameter of d1 through-holes in an axial direction and is connected to cylindrical through-hole, and extends to the inside of the filter.
Further, the filter is truncated cone and inner hollow, is along the circumferential direction provided with vertical strip and crosses water seam
Gap.
The utility model has the advantages that：
1）Monolithic construction is readily produced；
2）Installation is especially easy, it is only necessary to the expansion bayonet of drain cap be aligned to the filtration hole of porous plate, firmly pressed down
Enter, the lower part that need not arrive porous plate is operated；
3）Not the phenomenon that loose or dislocation is not will produce in operational process.
Other than objects, features and advantages described above, the utility model also has other purposes, feature and excellent
Point.Below with reference to figure, the utility model is described in further detail.
Description of the drawings
Fig. 1 is the structural schematic diagram that the utility model monoblock type expands bayonet drain cap.
Fig. 2 is the structural schematic diagram that the utility model monoblock type expands that bayonet drain cap is mounted on porous plate.
Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
In conjunction with Fig. 1-2, a kind of monoblock type expansion bayonet drain cap, which is characterized in that including intermediate plate 2, be located at intermediate plate 2
The filter 1 of upper end and expansion bayonet 3 positioned at 2 lower end of intermediate plate, the filter 1, intermediate plate 2 and expansion 3 three of bayonet are to connect
Be connected together monoblock type, and the expansion bayonet 3 can be installed in the filtration hole of porous plate 4.
3 top half of expansion bayonet is cylinder, and 3 lower half portion of expansion bayonet is inversed taper platform shape.
The diameter d of the cylinder is less than the diameter D of the filtration hole, and the upper surface diameter of the inversed taper platform shape is more than institute
State the diameter D of filtration hole so that the inversed taper platform shape part of expansion bayonet 3 is installed on porous plate 4 after capable of passing through the filtration hole
On.
The centre of the cylinder is provided with the through-hole of a diameter of d1 in an axial direction, and the centre of the inversed taper platform shape is provided in an axial direction
It a diameter of d1 through-holes and is connected to cylindrical through-hole, and extends to the inside of the filter 1.
The filter 1 is truncated cone and inner hollow, is along the circumferential direction provided with vertical strip and crosses water gap.
The thickness of the porous plate 4 is H, and the cylindrical part height of expansion bayonet 3 is h1.
When installation, it is only necessary to the expansion bayonet 3 of drain cap is aligned to the filtration hole of porous plate 4, is firmly pressed downwards,
Drain cap is installed in the filtration hole of porous plate 4.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, the invention may be variously modified and varied.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
