Abstract
The utility model discloses a liquid phase analytic system bottom seal structure, it includes: the end face seal circle, the sealing washer intracavity that end face seal circle holding encloses at column jacket, feed liquid distributor and gland nut, the end face seal circle has the lip circle body to be provided with the elastic support body between the upper lip of lip circle body and the lower lip in the recess that forms. The utility model discloses can improve its sealing performance, messenger's liquid phase analytic system also can steady job under great pressure.
Description
Technical field
This utility model relates to a kind of liquid phase analysis system bottom and seals structure, is mainly used in the separating-purifying of medicine, factory, laboratory, the analysis of liquid component, liquid substance.
Background technology
At present, it is operationally that internal pressure requirements is higher that liquid-phase chromatographic column analyzes system, and general work pressure is 6-8MPA, and this just requires that cylinder has good sealing property, if a seal leakage can cause the failure of an experiment.Cylinder seals the difficult problem being always up in the industry, and the liquid phase analysis system bottom of prior art adopts conventional seals circle to seal, and does not reach sealing effectiveness well.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of liquid phase analysis system bottom seals structure, and it can improve its sealing property, makes the work that liquid phase analysis system also can be stable under bigger pressure.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of liquid phase analysis system bottom seals structure, and it includes:
End-face seal ring, described end-face seal ring is contained in the sealing ring intracavity that column jecket, feed liquid allotter and clamp nut surround, and described end-face seal ring has lip circle body, and is provided with elastic support in the groove formed between the upper lip of lip circle body and lower lip.
Further provide a kind of concrete structure forming sealing ring chamber, the upper end of described feed liquid allotter has separation step, described clamp nut passes through screwed on column jecket, and separating together with step is connected to the lower end of column jecket by screwing clamp nut by the upper end of feed liquid allotter, the outside of described separation step, the upper end of feed liquid allotter, the inner side of clamp nut and the lower end of column jecket surround described sealing ring chamber.
Further for improving its sealing property better, the inner side of described separation step and the top of feed liquid allotter surround filtration sieve plate chamber, filter sieve plate intracavity and are equipped with filtration sieve plate, separate and are provided with side seal circle between step and the sidewall filtering sieve plate.
After have employed technique scheme, this utility model have employed novel end-face seal ring at sealing ring intracavity, it is provided with elastic support in this end-face seal ring, when pressurized, its interior elastic support can be good at end face seal is enclosed the effect of elastic compensating, makes end-face seal ring closely compress with column jecket and feed liquid allotter respectively, and the more big sealing of pressure is more tight, experiments show that, it is possible to bear the pressure of 15MPa, and obtain better analytical effect than ever.
Accompanying drawing explanation
Fig. 1 is the structural representation that liquid phase analysis system bottom of the present utility model seals structure.
Detailed description of the invention
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and in conjunction with accompanying drawing, this utility model is described in further detail.
As it is shown in figure 1, a kind of liquid phase analysis system bottom seals structure, it includes:
End-face seal ring 1, described end-face seal ring 1 is contained in the sealing ring intracavity that column jecket 2, feed liquid allotter 3 and clamp nut 4 surround, described end-face seal ring 1 has lip circle body, and is provided with elastic support 11 in the groove formed between the upper lip of lip circle body and lower lip.
The upper end of described feed liquid allotter 3 has separation step 31, described clamp nut 4 passes through screwed on column jecket 2, and separating together with step 31 is connected to the lower end of column jecket 2 by screwing clamp nut 4 by the upper end of feed liquid allotter 3, the outside of described separation step 31, the upper end of feed liquid allotter 3, the inner side of clamp nut 4 and the lower end of column jecket 2 surround described sealing ring chamber.
The inner side of described separation step 31 and the top of feed liquid allotter 3 surround filtration sieve plate chamber, filter sieve plate intracavity and are equipped with filtration sieve plate 5, separate and be provided with side seal circle 6 between step 31 and the sidewall filtering sieve plate 5.
Operation principle of the present utility model is as follows:
This utility model have employed novel end-face seal ring 1 at sealing ring intracavity, it is provided with elastic support 11 in this end-face seal ring 1, when pressurized, its interior elastic support 11 can be good at end-face seal ring 1 is played the effect of elastic compensating, make end-face seal ring 1 closely compress with column jecket 2 and feed liquid allotter 3 respectively, and the more big sealing of pressure is more tight, experiments show that, the pressure of 15MPa can be born, and obtain better analytical effect than ever.
Particular embodiments described above; this utility model is solved the technical problem that, technical scheme and beneficial effect have further described; it is it should be understood that; the foregoing is only specific embodiment of the utility model; it is not limited to this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
