Abstract
The utility model relates to a sealing structure of a high-pressure injection needle valve hole. The sealing structure of the high-pressure injection needle valve hole comprises a valve body provided with the high-pressure injection needle valve hole, and is characterized in that a hole bottom of the high-pressure injection needle valve hole is set to a conical hole with a platform; a soft conical mat with a platform is arranged on the conical hole; a through hole arranged on the bottom of the conical mat is connected with the conical hole; a pressing sleeve is inserted into the high-pressure injection needle valve body so as to tightly press the platform of the conical mat onto the platform of the conical hole.
Description
Technical field
The sealing configuration of the utility model and a kind of entry needle valve opening, specifically a kind of sealing configuration of high-pressure injection needle valve hole.
Background technique
At present, the sealing cone between the more difficult processing of the sealing cone of traditional entry needle valve opening and needle does not reach highi degree of accuracy laminating, for high-pressure liquid sealing incessantly.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of sealing configuration of high-pressure injection needle valve hole.
In order to solve the problems of the technologies described above, the sealing configuration of a kind of high-pressure injection needle valve hole of the present utility model, comprise the valve body that contains high-pressure injection needle valve hole, it is characterized in that, to at the bottom of the hole of high-pressure injection needle valve hole, be arranged to the taper hole with platform, a soft cone pad with platform is set on taper hole, the through hole of boring the setting of rebasing portion communicates with taper hole, in high-pressure injection needle valve body, be bumped into a gland, the platform of cone pad is pressed on the platform of taper hole.
Adopt the design's beneficial effect to be: the conical surface between original needle and valve opening is sealed firmly, become the sealing between needle and soft cone pad, because the amount of deformation of soft material is larger, the effect of its extension laminating leakage-gap is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing configuration of a kind of high-pressure injection needle valve hole of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the sealing configuration of a kind of high-pressure injection needle valve hole of the present utility model is described in further detail.
As shown in the figure, the sealing configuration of a kind of high-pressure injection needle valve hole of the present utility model, comprise the valve body 2 that contains high-pressure injection needle valve hole 1, it is characterized in that, by the taper hole 4 of being arranged at the bottom of the hole of high-pressure injection needle valve hole 1 with platform 3, a soft cone pad 5 with platform is set on taper hole 4, the through hole that cone pad 5 bottoms arrange communicates with taper hole 4, in high-pressure injection needle valve body, be bumped into a gland 7, the platform of cone pad 5 is pressed on the platform 3 of taper hole 4.
