Abstract

The utility model relates to a high-pressure sealing plug which comprises a plug mounted on a valve body processing hole, wherein a sealing ring is arranged on the plug; the diameter of the plug and the processing hole are in interference fit connection; a ring-shaped groove is formed in the outer wall of the plug; and the sealing ring is arranged in the ring-shaped groove. The riveting pressure type high-pressure sealing plug is used for a few holes smaller than 3 mm, so that the characteristics of stable and reliable quality and good sealing performance are achieved; and meanwhile, the riveting pressure efficiency is high, noise is not generated, the riveting pressure plugging consistency is good, further, the mounting requires no special space, and the integrated valve group space is small.

Description

A kind of High Pressure Sealing Gland
Technical field
The utility model relates to a kind of High Pressure Sealing Gland, belongs to the hydraulic element technical field of sealing technology.
Background technique
Make the field at hydraulic element, often need make auxiliary hole, to realize the connection between the different ducts, behind hole link, the technology aperture need be stopped up usually; The sealing configuration that widely uses in this field at present comprises the screw plug of taper screw plug and other structures, the screw plug of these two kinds of structures can satisfy general seal request, yet, all have some shortcomings separately, cone blocking can't guarantee reliable sealing, and the screw plug head installation dimension of other structures is bigger, thereby influence the structural design of hydraulic element, for this reason, need to develop a kind of both had good seal action, the auxiliary hole sealing configuration that has less installation dimension again.
Summary of the invention
Technical problem to be solved in the utility model is: propose a kind of High Pressure Sealing Gland, by increasing seal ring, adopt soft seal and hard sealing structure combining, make the steady quality of seal plug reliable, good seal performance.
The technological scheme that the utility model solves above technical problem is: a kind of High Pressure Sealing Gland is provided, comprise the plug that is installed on the valve body auxiliary hole, be provided with seal ring at described plug, adopt interference fit to be connected between described plug diameter and the described auxiliary hole, the outer wall of described plug is provided with an annular groove, and described seal ring is arranged in the described annular groove.
The technological scheme that the utility model further limits is: aforesaid High Pressure Sealing Gland, and around described valve body auxiliary hole, adopt pressure-riveting process that described plug is stuck in the described auxiliary hole, unlikelyly because of internal pressure plug is flown out.
Aforesaid High Pressure Sealing Gland, the upper end of described plug are provided with the shoulder groove that cooperates with described pressure-riveting process, and the width of the shoulder groove by regulating plug can be controlled the bearing capacity of plug.
Further, aforesaid High Pressure Sealing Gland also is provided with the plug dress and gets the hole on the described plug, conveniently use when the installation and removal plug.
The utility model has the advantages that: the utility model for some less than some hole of 3mm by using the High Pressure Sealing Gland of riveting type, it is reliable to have steady quality, the characteristics of good seal performance, the efficient that presses simultaneously height, do not produce noise, the shutoff high conformity that presses, and do not need special space mounting, make integrated valve group space little.
Description of drawings
Fig. 1 is plug structural representation of the present utility model.
Fig. 2 is the utility model plug scheme of installation before pressing.
Fig. 3 is that the utility model is at the back plug scheme of installation that presses.
Embodiment
Embodiment one
Present embodiment provides a kind of High Pressure Sealing Gland, structure as shown in Figure 1 to Figure 3, comprise the plug 1 that is installed on the valve body auxiliary hole 4, be provided with seal ring 2 at plug 1, adopt interference fit to be connected between plug diameter and the auxiliary hole, the outer wall of plug is provided with an annular groove 3, seal ring is arranged in the annular groove, around valve body auxiliary hole 4, adopt pressure-riveting process that plug is stuck in the auxiliary hole, be provided with the shoulder groove 5 that cooperates with pressure-riveting process in the upper end of plug, also be provided with the plug dress simultaneously on the plug and get hole 6.
After the plug of present embodiment is loaded onto seal ring, because the cylindrical of plug and auxiliary hole adopt interference fit, be pressed into valve body again by external force.Use special-purpose drift with the material riveting around the auxiliary hole then, because material and the firmly clamping of plug shoulder groove that the part behind the riveting is outstanding, unlikelyly because of internal pressure plug is flown out, can control the bearing capacity of plug by the shoulder width of regulating plug, the efficient height that presses of present embodiment does not produce noise, and the shutoff high conformity presses, installation dimension is less simultaneously, and it is little to take up space.
The utility model can also have other mode of execution, and the technological scheme that the equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
