Abstract
The invention relates to a sealing structure of a backwashing filter, and aims at solving the problem that a sealing ring is easily extruded out from a flange disk. The sealing structure comprises a barrel body and a circular-ring-shaped sealing ring, wherein the sealing ring is provided with a helical tail unit; the tail unit is integrated with the sealing ring; a sealing ring mounting slot is formed in the upper edge of the barrel body; a sealing ring tail unit channel is formed in the sealing ring mounting slot in the barrel body along the axial line direction of the barrel body. On the basis that no new structural member is added, the problem that the sealing ring is easily extruded out is solved, and the execution process is simple and convenient.
Description
Technical field
The present invention relates to the improvement of backwash filter structure, particularly a kind of hermetically-sealed construction of backwash filter.
Background technology
Existing filter makes filter in the process run, there is the problem of pressure oscillation because the effective length of filter core shortens, and the sealing ring that the fluctuation of pressure result in filter core gland is extruded from upper flange plate, cause the frequent leakage of liquid, this problem, to producing the very large danger brought, easily causes sending out of accident.Chinese patent CN203507665U discloses " backwash filter of improvement ", this utility model solves this problem by interpolation pull bar and corresponding construction, but because need to do larger change to existing structure of container, therefore implementation process relative complex, dismounting bothers.
Summary of the invention
For overcoming problems of the prior art, the invention provides the hermetically-sealed construction of a kind of good sealing effect, simple, the convenient backwash filter implemented of structure.
The present invention solves the technical scheme that its technical problem takes: the hermetically-sealed construction of this kind of backwash filter, comprise cylindrical shell, sealing ring, filter core and blind flange, it is characterized in that, described sealing ring is annular, described sealing ring is with the empennage of spiral, and described empennage and sealing ring are integrated; Described cylindrical shell upper edge is provided with sealing ring mounting groove, and described sealing ring mounting groove has sealing ring empennage passage along tubular axis direction on cylindrical shell.
Further, described empennage rotating cycle is at least half-turn.
Further, described empennage end is most advanced and sophisticated.
Further, described sealing ring empennage passage is helical form.
Further, described sealing ring empennage passage and empennage are matched in clearance.
To sum up, the beneficial effect of technique scheme of the present invention is as follows: make the coordinating of the empennage of sealing ring and empennage passage between sealing ring with sealing ring mounting groove coordinate more firm, solve and occur because of problems such as pressure oscillations the problem that sealing ring is extruded, and improvement does not increase new structure member, makes implementation process simpler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of sealing ring mounting groove of the present invention.
Fig. 3 is sealing ring stereogram of the present invention.
In figure: 1 cylindrical shell, 2 sealing rings, 3 filter cores, 4 blind flanges, 5 sealing ring mounting grooves, 6 sealing ring empennage passages, 7 empennages, 8 is most advanced and sophisticated, 9 sealing ring empennage feeder connections.
Detailed description of the invention
Be described in detail to characteristic sum principle of the present invention below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the present invention, not limits protection scope of the present invention with this.
A hermetically-sealed construction for backwash filter, as shown in Figure 1, comprises cylindrical shell, sealing ring, filter core and blind flange.
As shown in Figure 3, described sealing ring is annular, and described sealing ring is with the empennage of spiral, and described empennage and sealing ring are integrated.The material that empennage has is identical with sealing ring, therefore has certain elasticity.Described empennage rotating cycle is at least half-turn, and the end of empennage is most advanced and sophisticated, easierly when making to install sealing ring empennage is inserted sealing ring empennage passage.
As shown in Figure 1, described sealing ring mounting groove has sealing ring empennage passage along tubular axis direction on cylindrical shell, and described sealing ring empennage passage is helical form.
As shown in Figure 2, sealing ring mounting groove has sealing ring empennage feeder connection.
During use, the tip of empennage is stretched into the end that sealing ring empennage feeder connection extends to sealing ring empennage passage always, in order to realize sealing ring better firm effect, described empennage rotating cycle is at least half-turn.In order to convenience when mounted, and raising sealing ring can keep not being extruded when the pressure effect of being fluctuated, and makes described empennage passage and empennage be matched in clearance.
Above-described embodiment is only the description carried out the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in the determined protection domain of claims of the present invention.
