Abstract
The utility model discloses the sealing device of filter element, it comprises filter core, upper end filter core flange, lower end filter core flange, upper locating ring, lower locating ring, upper end filter core flange, lower end filter core flange is all connected in aggregates with filter core, it also comprises upper and lower two U-shaped sealing rings, upper U-shaped sealing ring is tightly placed on the filter core flange of upper end, the inner ring surface close contact of outside and filter core upper flange, its inner face is provided with locating ring, lower U-shaped sealing ring is tightly placed on the filter core flange of lower end, the inner ring surface close contact of outside and filter core lower flange, its outer face is provided with lower locating ring.Upper U-shaped sealing ring, by filter core upper flange and upper end filter core flange screw, makes the gap of filter core upper flange and upper end filter core flange be sealed; Lower U-shaped sealing ring by filter core lower flange and lower end filter core flange compress, the gap between filter core lower flange and lower end filter core flange is sealed.Therefore, the good sealing effect of this new type sealing device, can not make filter core occur drainage.
Description
Technical field
The utility model is the sealing device of filter element; it is applicable in the filter of various source water, cooling water, fresh water (FW), waste water and agricultural irrigation water; there is good sealing effect, corrosion-resistant, convenient to disassembly; be applicable to large-scale production; and production cost is lower, is applicable to the industries such as chemical industry and uses.
Background technology
Cartridge seal effect in the various filter of current China is not ideal, and mainly because the sealing ring in filter core easily comes off, drainage is relatively more serious, and the especially sealing ring of sawtooth pattern, sealing effectiveness is very bad, is easy to be washed out by water, causes and comes off.Fig. 4, Fig. 5, Figure 6 shows that the schematic diagram (in figure, front is the direction of current) of current sawtooth pattern sealing ring, as can be seen from the figure, sawtooth pattern sealing ring on filter core can upwards inwardly tilt under the impact of water, flange at the bottom of itself and filter cylinder or filtering cartridge lid flange is made to form gap thus leak, time has been grown and has been easy to be washed out from upper end filter core flange or lower end filter core flange by water, thus causes filter core seriously to leak.
Summary of the invention
Problem to be solved in the utility model is to provide the novel a kind of sealing device of filter element, and its sealing effectiveness is fabulous, and filter core can not be made to occur drainage.Meanwhile, this novel sealing device cost is low, dismounting, easy for installation.
The sealing device of the utility model filter element, it comprises filter core, upper end filter core flange, lower end filter core flange, upper locating ring, lower locating ring, upper end filter core flange, lower end filter core flange are all connected in aggregates with filter core, it also comprises upper and lower two U-shaped sealing rings, upper U-shaped sealing ring is tightly placed on the filter core flange of upper end, outside inner ring surface close contact with filter core upper flange, its inner face are provided with locating ring, and lower U-shaped sealing ring is tightly placed on the filter core flange of lower end, the inner ring surface close contact of outside and filter core lower flange, its outer face are provided with lower locating ring.
The technical scheme that the utility model cartridge seal device adopts is: upper U-shaped sealing ring is by filter core upper flange and upper end filter core flange screw, and be in the inner face of the upper locating ring on filter core upper flange step surface near upper U-shaped sealing ring, the gap of filter core upper flange and upper end filter core flange is sealed, ensures that the water after filtering can not overflow; Lower U-shaped sealing ring by filter core lower flange and lower end filter core flange compress, the gap between filter core lower flange and lower end filter core flange is sealed, ensures that the water of water inlet can not pass through.Therefore, the good sealing effect of this new type sealing device, can not make filter core occur drainage, is adapted at using in the filter core of various filter.

Detailed description of the invention
From Fig. 1, Fig. 2, Fig. 3 is known, the sealing device of the utility model filter element, it comprises filter core 1, upper end filter core flange 2, lower end filter core flange 3, upper locating ring 4, lower locating ring 5, upper end filter core flange 2, lower end filter core flange 3 is all connected in aggregates with filter core 1, it also comprises upper and lower two U-shaped sealing ring 6-1, 6-2, upper U-shaped sealing ring 6-1 is tightly placed on upper end filter core flange 2, the inner ring surface close contact of outside and filter core upper flange 7, its inner face is provided with locating ring 4, lower U-shaped sealing ring 6-2 is tightly placed on lower end filter core flange 3, outside contacts with the inner ring surface of filter core lower flange 8, its outer face is provided with lower locating ring 5.
As a kind of improved procedure that this is novel, the sealing device of filter element also comprises O type circle 9, is provided with O RunddichtringO 9 between upper end filter core flange 2 and filter cylinder end flanges 10.Like this, the lateral surface of upper end filter core flange 2 is close to the inwall of filter cylinder end flanges 10, ensures that the water after filtering does not overflow further, thus ensures the reliability of sealing.
The technical scheme that the utility model cartridge seal device adopts is: upper U-shaped sealing ring 6-1 is compressed by filter core upper flange 7 and upper end filter core flange 2, and be in the inner face of the upper locating ring 4 on filter core upper flange 7 step surface near upper U-shaped sealing ring 6-1, filter core upper flange 7 is sealed with the gap of upper end filter core flange 2, ensures that the water after filtering can not overflow; Lower U-shaped sealing ring 6-2 is compressed by filter core lower flange 8 and lower end filter core flange 3, and the gap between filter core lower flange 8 and lower end filter core flange 3 is sealed, and ensures that the water of water inlet can not pass through.Therefore, the good sealing effect of this new type sealing device, can not make filter core occur drainage, is adapted at using in the filter core of various filter.Meanwhile, the U-shaped sealing ring during this is novel and O RunddichtringO are rubber seal, corrosion-resistant, and this novel sealing device is quick and easy for installation, and yield rate is high, and production cost is lower, are applicable to various filter core and use.
