Abstract
The utility model discloses a thread locking type filter cartridge pressure-resistant sealing ring which comprises a ring body, wherein the bottom of the ring body is provided with a circle of ring bottom groove. Due to the technical scheme, when the thread of a filter cartridge is locked, the ring top of the sealing ring abuts against the groove surface at the top of a filter cartridge cover, and the ring bottom abuts against the sealing surface of the filter cartridge so that the sealing ring does not move or deform and prevents leakage at low pressure; when pressure in the cartridge body is high, the ring bottom groove is automatically opened, and the ring top and the ring bottom are compacted with the top of the filter cartridge cover and the sealing surface of the filter cartridge respectively, wherein the compaction is tighter with the increasing pressure; and therefore, the problem of water leakage of the filter cartridge operating under high pressure is thoroughly solved.
Description
Technical field
The utility model relates to a kind of seal ring, especially a kind of mouth locking filter cylinder compressive resistance seal ring.
Background technique
In water treatment field, especially in water purification plant, often use filter cylinder to be used for putting filter element; Like the cotton filter core of PP, active carbon filter core, milipore filter, reverse osmosis membrane etc.; For avoiding the seepage of water, filter cylinder needs sealing, uses seal ring at cover and cylindrical shell joint.Seal ring in the past, the one side inconsistent with cylindrical shell is plane form, through the silk mouthful chucking of cover and cylindrical shell.When the filter cylinder inner filter element need be carried out backwash; Hydraulic pressure can raise in the filter cylinder; Water backs down the joint of cover and cylindrical shell; Because seal ring and the inconsistent one side of cylindrical shell are plane form, make the telescopic level of seal ring can not satisfy the rising degree of hydraulic pressure, cause sealing not exclusively to make seepage.
The model utility content
The utility model technical problem to be solved provides a kind of mouth locking filter cylinder compressive resistance seal ring, makes sealing effect desirable, and the seepage of water does not take place when hydraulic pressure is higher especially.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: silk mouthful locking filter cylinder compressive resistance seal ring, comprise circle body, and the bottom part ring of said circle body is provided with circle end groove.
As preferably, groove is a V-arrangement at the bottom of the said circle.
As preferably, the bottom of groove is an arc transition at the bottom of the said circle.
As preferably, the inner ring of said circle body is equipped with the inner ring groove.
As preferably, said inner ring groove is a V-arrangement.
As preferably, the degree of depth of said inner ring groove is half the greater than said circle body wall thickness.
The utility model is owing to adopted technique scheme, and when filter cylinder silk mouth was locked, the groove face of filter cylinder tops was being supported on seal ring circle top; Circle is supporting the filter cylinder sealing surface in the end, so seal ring can not walk, be out of shape, and sealing is non-leakage during low pressure; And when cylinder internal pressure was high, circle end groove can be opened automatically, the circle top and the circle end respectively with filter cylinder caping and filter cylinder sealing surface compact; Pressure is high more to be pushed up tightly more, the problem of having leaked when thoroughly having solved the filter cylinder high-voltage operation.

Embodiment
Further describe below in conjunction with the embodiment of accompanying drawing the utility model.
Shown in Figure 1 is the utility model silk mouth locking filter cylinder compressive resistance seal ring, comprises circle body 1, and the bottom part ring of said circle body 1 is provided with circle end groove 11.Groove 11 is a V-arrangement at the bottom of the said circle, and the bottom of groove 11 is an arc transition at the bottom of the said circle.The inner ring of said circle body 1 is equipped with inner ring groove 12.Said inner ring groove 12 is a V-arrangement, and the degree of depth of said inner ring groove 12 is half the greater than said circle body 1 wall thickness.The cylindrical shell sealing surface of the circle end and filter cylinder is inconsistent, and the circle top is inconsistent with the groove face of filter cylinder cover.
This structure makes seal ring can not walk, be out of shape; Sealing is non-leakage during low pressure; And when cylinder internal pressure was high, circle end groove can be opened automatically, the circle top and the circle end respectively with filter cylinder caping and filter cylinder sealing surface compact; Pressure is high more to be pushed up tightly more, the problem of having leaked when thoroughly having solved the filter cylinder high-voltage operation.
