CN105715794A - High-pressure sealing device - Google Patents

Abstract

The invention relates to a high-pressure sealing device which comprises a first part and a second part. The first part is provided with a bottom and a first end. The second part is provided with a top, a boss and a second end. The bottom of the first part and the top of the second part are connected, and the first end of the first part is arranged on the boss of the second part in a propped mode and then is connected with the second end. According to the high-pressure sealing device, the boss effectively prevents an O-shaped ring from being extruded out, and therefore leakage is effectively prevented.

Description

High-pressure sealed device

Technical field

The present invention relates to a kind of obturator, particularly relate to a kind of high-pressure sealed device.

Background technology

O seals structure due to its simple in construction, easy to manufacture, with low cost, easy for installation and be widely used in various field.

Existing O seals structure, although can reach the effect sealed, but have its limitation.

Or sealing property is higher, but very inconvenient and damage O very easily when mounted when installing.

Or the schematic diagram of prior art as shown in Figure 1, part 91 and part 92 easily form gap 90 at mating surface after being stressed, thus causing that O 93 is extruded and revealed.

Summary of the invention

It is an object of the invention to the defect for prior art, it is provided that a kind of high-pressure sealed device can effectively prevent the extrusion of O, thus effectively preventing from revealing.

For achieving the above object, the invention provides a kind of high-pressure sealed device, described high-pressure sealed device includes: first component and second component；

Described first component has bottom and first end；Described second component has top, boss and the second end；

The top of the bottom of described first component and described second component connects, and the first end of described first component connects with described the second end after riding upon the boss of described second component.

Further, between the bottom of described first component and first end, there is holding part, be used for housing O.

The high-pressure sealed device of the present invention, because the existence of boss, is effectively prevented the extrusion of O, thus effectively preventing from revealing.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of prior art；

Fig. 2 is the schematic diagram of the high-pressure sealed device of the present invention；

Fig. 3 is the schematic diagram of first component；

Fig. 4 is the schematic diagram of second component；

Fig. 5 is the operating diagram of the high-pressure sealed device of the present invention.

Detailed description of the invention

Below by drawings and Examples, technical scheme is described in further detail.

Fig. 2 is the schematic diagram of the high-pressure sealed device of the present invention, as it can be seen, the high-pressure sealed device of the present invention includes first component 1 and second component 2.

Fig. 3 is the schematic diagram of first component, and first component has bottom 10 and first end 11.It addition, there is holding part 12 between the bottom 10 of first component and first end 11, it is used for housing O.

Fig. 4 is the schematic diagram of second component, and second component has top 20, the second end 21 and boss 22.

Shown in above three figure, the top 20 of the bottom of first component 1 10 and second component 2 connects, and the first end 11 of first component 1 connects with the second end 21 after riding upon the boss 22 of second component 2.Accommodating O 3 in holding part 12.

Fig. 5 is the operating diagram of the high-pressure sealed device of the present invention, and operationally, first component 1 and second component 2 under high pressure likely produce gap 4.But being because the existence of boss 22, the first end 11 of first component 1 still rides upon on the boss 22 of second component 2, so O 3 will not be revealed because of extrusion.Thus effectively prevent the impact on sealing of gap that first component 1 and second component 2 formed after pressurized.

Above-described detailed description of the invention; the purpose of the present invention, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only the specific embodiment of the present invention; the protection domain being not intended to limit the present invention; all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
