Problems solved by technology

For example, in the petroleum industry, the rubber cartridge used in oil production can also be regarded as a kind of sealing ring. If the rubber cartridge cannot withstand the pressure and temperature required for oil production, the seal of the rubber cartridge will fail, which will seriously affect the oil production output.

Embodiment Construction

[0047] Such as Figure 1-Figure 4 As shown, a detection device for detecting the sealing performance of the sealing ring 10 includes an inner cylinder liner 3, an outer cylinder liner 1, a forward pressure member providing axial pressure F, a sleeve 4, a limit ring 12 and Leak detection parts.

[0048] Wherein, the inner cylinder liner 3 and the outer cylinder liner 1 are arranged vertically and coaxially. Such as figure 2 and Figure 7 As shown, the outer cylinder liner 1 is sleeved on the outside of the inner cylinder liner 3 . An annular gap 11 is formed between the inner cylinder liner 3 and the outer cylinder liner 1. The sealing ring 10 is sleeved on the outer surface of the inner cylinder liner 3 and placed in the gap 11. When the sealing ring 10 is compressed axially due to the action of pressure, the sealing ring 10 protrudes radially outward and radially inward to contact with the inner surface of the outer cylinder liner 1 and the outer surface of the inner cyli...

Abstract

The invention relates to the sealing technical field, and particularly relates to a detection apparatus for detecting the sealing performance of the sealing ring under the high-temperature and / or high-pressure environment. The sealing ring sealing performance detection apparatus includes an inner cylinder liner, an outer cylinder liner, a forward pressing member, and a sleeve, the sleeve has a guide block projecting on the outer surface, and the guide block is close to the lower bearing part. According to the invention, the distance between the guide block and the inner wall of the outer cylinder liner is shorter, so that in the compression process of the sealing ring, if the sleeve inclines in the vertical direction, the guide block abuts against the inner wall of the outer cylinder liner to prevent the further inclination of the sleeve, so that the sealing ring can always bear the pressure in the vertical direction, and the reliability of the detection apparatus can be guaranteed.

Description

technical field [0001] The present application relates to the field of sealing technology, in particular to a detection device for detecting the sealing performance of a sealing ring in a high temperature or / and high pressure environment. Background technique [0002] The seal ring is a kind of seal commonly used in industrial products, and the seal ring is generally made of rubber materials. Various fields have different requirements for the pressure and temperature that the sealing ring can withstand. In order to determine whether the sealing ring meets the requirements, the sealing ring needs to be tested. For example, in the petroleum industry, the rubber cartridge used in oil production can also be regarded as a kind of sealing ring. If the rubber cartridge cannot withstand the pressure and temperature required for oil production, it will cause the seal failure of the rubber cartridge and seriously affect the oil production output. Contents of the invention [0003] ...
