Description

Technical Field

[0001] This utility model relates to the technical field of sealing ring testing equipment, and in particular to a sealing ring testing carrier. Background Technology

[0002] In mold water system systems, the reliability of the sealing rings directly affects the sealing performance of the coolant or oil, especially under high temperature (80-150℃) and circulating pressure (0.5-2.0MPa) conditions. Sealing rings are prone to leakage due to material aging, thermal expansion mismatch, or fatigue cracks. It is necessary to select suitable sealing rings to match the water system. Currently, there is a lack of sealing ring testing equipment on the market, making it impossible for users to know the various performance characteristics of the sealing rings. Therefore, there is an urgent need to develop a sealing ring testing device. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a sealing ring testing carrier.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sealing ring testing carrier, comprising an upper template and a lower template, which are closed by a locking assembly to form a testing cavity; multiple continuously connected flow hole groups, spaced apart along the length of the template, each flow hole group including a first flow channel hole of the upper template and a second flow channel hole coaxially connected to the lower template; sealing rings, disposed on the closed end faces of the upper and lower templates, and surrounding the outer edge of each flow hole group; an inlet pipe and an outlet pipe, respectively connecting the first and last flow hole groups; and a flow channel separation structure, disposed within each flow hole group, allowing fluid to flow along a preset meandering path through the inner area of ​​all sealing rings.

[0005] As a preferred embodiment of this utility model, the flow channel partition structure includes: a first partition plate disposed in each first flow channel hole, dividing the first flow channel hole into a left chamber and a right chamber; a second partition plate disposed in each second flow channel hole, dividing the second flow channel hole into a left chamber and a right chamber; a guide hole is provided at the end of the second partition plate away from the first partition plate, so that the left chamber and the right chamber of each flow hole group are connected in sequence to form a meandering flow channel path from the inlet pipe to the outlet pipe.

[0006] As a preferred embodiment of this utility model, the guide hole is a semi-circular hole disposed on the upper end of the second partition plate.

[0007] As a preferred embodiment of this utility model, the closed end face of the upper template and / or the lower template is provided with an annular groove, the annular groove is located at the junction of the outer edges of the first flow channel hole and the second flow channel hole, and the sealing ring is embedded in the annular groove.

[0008] As a preferred embodiment of this utility model, the locking assembly includes bolts located at the four corners of the lower template and threaded holes at the four corners of the upper template that match the bolts.

[0009] As a preferred embodiment of this utility model, the diameter of the flow hole group decreases gradually along the direction from the inlet pipe to the outlet pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the meandering flow path formed by the flow channel separation structure, the test fluid is forced to flow through the inner area of ​​all sealing rings, which truly simulates the actual working conditions of multiple sealing rings in parallel, dynamic pressure impact and temperature alternation in the mold water circuit, overcomes the limitations of traditional single-point static testing, and realizes the synchronous detection of multiple sets of sealing rings.

Detailed Implementation

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] like Figures 1 to 5The sealing ring testing carrier shown includes an upper template 1 and a lower template 2, which are closed by a locking assembly 3 to form a test chamber; multiple continuously connected flow hole groups 4 are arranged at intervals along the length of the template, each flow hole group 4 includes a first flow channel hole 5 of the upper template 1 and a second flow channel hole 6 coaxially connected to the lower template 2; sealing rings 7 are disposed on the closed end faces of the upper template 1 and the lower template 2, and surround the outer edge of each flow hole group 4; an inlet pipe 8 and an outlet pipe 9 are respectively connected to the first and last flow hole groups 4; a flow channel separation structure is disposed in each flow hole group 4, so that the fluid flows through the inner area of ​​all sealing rings 7 along a preset meandering path. After the test is completed, the carrier is opened, and there is liquid leakage at the failed sealing ring 7 on the closed end faces of the upper template 1 and the lower template 2. The meandering path directly exposes the leakage point to the oil seepage area outside the sealing ring 7, and the leakage location can be visually located without additional sensors, thus improving the detection efficiency.

[0020] The meandering flow path formed by the flow channel separation structure forces the test fluid to flow through the inner area of ​​all sealing rings 7, realistically simulating the actual working conditions of multiple sealing rings 7 connected in parallel, dynamic pressure impact and temperature alternation in the mold water circuit, overcoming the limitations of traditional single-point static testing, and realizing the synchronous detection of multiple sets of sealing rings 7.

[0021] The flow channel partition structure includes: a first partition plate 10 disposed in each first flow channel hole 5, dividing the first flow channel hole 5 into a left chamber 12 and a right chamber 13; a second partition plate 11 disposed in each second flow channel hole 6, dividing the second flow channel hole 6 into a left chamber 12 and a right chamber 13; a guide hole 14 is provided at the end of the second partition plate 11 away from the first partition plate 10, so that the left chamber 12 and the right chamber 13 of each flow hole group 4 are connected in sequence to form a meandering flow channel path from the inlet pipe 8 to the outlet pipe 9. In this embodiment, the guide hole 14 is a semi-circular hole 15 or a round hole disposed at the upper end of the second partition plate 11. It should be noted that the lower end of the first partition plate 10 is sealed to the bottom of the first flow channel hole 5.

[0022] The closed end face of the upper template 1 and / or the lower template 2 is provided with an annular groove 16. The annular groove 16 is located at the junction of the outer edges of the first flow channel hole 5 and the second flow channel hole 6, and the sealing ring 7 is embedded in the annular groove 16.

[0023] The locking assembly 3 includes bolts 17 located at the four corners of the lower template 2 and threaded holes 18 at the four corners of the upper template 1 that match the bolts 17.

[0024] The diameter of the flow hole group 4 decreases gradually along the direction from the inlet pipe 8 to the outlet pipe 9. Similarly, the diameter of the sealing ring 7 also gradually decreases, allowing for durability testing of sealing rings 7 of different sizes.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
