AI Technical Summary
Traditional rubber capsules are prone to explosion in high-temperature and high-pressure tests of vulcanizers, which pose safety hazards and are costly, and cannot effectively withstand high-temperature and high-pressure media.
A spherical mask formed of cast iron is designed instead of rubber capsules. The outer diameter of the spherical mask is equivalent to the outer diameter of the ring seat flange at the air outlet of the mechanism. It is equipped with a sealing ring and a hook, which can wrap the air outlet flange and form a sealing structure.
The spherical mask can effectively withstand high temperature and high pressure media, avoid explosion risks, improve test safety, and reduce costs due to the long life of the material and can be reused.

Abstract
Description
Technical field:
[0001] The utility model belongs to the field of giant tire manufacturing, and particularly relates to a high-temperature and high-pressure test machine cover of a vulcanizing machine, which can be used to replace a capsule for testing. Background technology:
[0002] Vulcanizers use high-temperature and high-pressure media. Whenever new equipment is debugged or overhauled, pressure tests and temperature measurements are required. Traditionally, rubber capsules that withstand corresponding pressures are used for pressure test simulations. Capsules are rubber products, and their pressure tolerance is limited. Often, due to equipment failures, the medium is continuously replenished, resulting in excessive pressure and causing the capsule to explode; especially the hot water medium in the giant tire capsule, with a temperature of up to 194 degrees and a pressure of up to 30 MPa. The risk of explosion is huge, the giant capsules are costly and the losses are heavy, and there are safety hazards in the test process. For this reason, it is necessary to transform the pressure test mode.
[0003] How to provide a more reasonable technical solution becomes the research object of the present invention. Summary of the invention:
[0004] The utility model aims to design a high-temperature and high-pressure test machine cover of a vulcanizing machine which is formed by cast iron to replace a bladder.
[0005] The technical solution of the utility model is achieved as follows: a vulcanizing machine high-temperature and high-pressure test machine cover, characterized in that: the main body is a cast iron spherical cover, the outer diameter of the bottom edge of the spherical cover is equivalent to the outer diameter of the ring seat flange at the air outlet of the mechanism, and bolt holes corresponding to the ring seat flange are opened, and the air outlet flange is wrapped in the spherical cover by means of bolts locked on the ring seat flange; the rotation center of the spherical cover is also formed with a raised portion that can accommodate the center rod of the air outlet flange, and a pair of hooks are respectively welded on the radial position of the spherical surface.
[0006] The thickness of the spherical cover is not less than 50 mm, and a sealing ring is arranged at the bottom edge.
[0007] The bottom edge of the spherical cover is processed with an embedding groove for partial embedding of the sealing ring, and the bolt hole is located in the middle of the embedding groove; the cross-section of the sealing ring is in the shape of a "convex" character, with a central ridge and an outward-flashed edge at the bottom, the central ridge can be embedded in the embedding groove of the bottom edge of the spherical cover, and the outward-flashed edge is padded between the bottom edge of the spherical cover and the ring seat flange to form a sealing structure.
[0008] The utility model utilizes a test machine cover instead of a rubber capsule to meet the need for testing steam boiler equipment. The output high-pressure hot steam medium circulates in and out of the cover, and the medium parameters are effectively and accurately detected. The test machine cover is a cast iron product with a long service life and can be reused. The installation and operation are more convenient, and production safety hazards can be eliminated.

[0017] Reference Figure 1 and Figure 2 The main body of the vulcanizer high temperature and high pressure test machine cover is a cast iron spherical cover 1, and the bottom edge 11 of the spherical cover is processed with bolt holes 12; more specifically, the thickness of the spherical cover 1 is not less than 50mm, and the outer diameter of the bottom edge 11 is equivalent to the outer diameter of the ring seat flange 21 at the mechanism outlet 2, and the bolt holes 12 opened correspond to the screw holes of the ring seat flange 21, and are locked on the ring seat flange 21 with the help of bolts 3, and the outlet flange 22 is wrapped in the spherical cover, that is, the high temperature and high pressure medium output from the outlet on the side of the outlet flange is wrapped in the spherical cover, which neither leaks out nor can withstand high temperature and high pressure. During operation, the bolts 3 are inserted from the bottom surface of the ring seat flange 21, and the threaded section is locked with the bolt holes 12. The mechanism outlet 2 mentioned here generally refers to steam boilers and related equipment.
[0018] The spherical cover 1 is also formed with a raised portion 13 at the rotation center to accommodate the central rod of the outlet flange 22, thereby making way for the position; the bottom edge 11 of the spherical cover is provided with a sealing ring 4, and in order to stably fix the sealing ring 4, the bottom edge 11 is processed with an embedding groove 14 for partial embedding of the sealing ring, and the bolt hole 12 is located in the middle of the embedding groove; the corresponding sealing ring 4 has a "convex"-shaped cross-section, with a central ridge 41 and an outward-flashed edge 42 at the bottom, the central ridge 41 can be embedded in the embedding groove 14 of the bottom edge of the spherical cover, and the outward-flashed edge 42 is padded between the bottom edge 11 of the spherical cover and the ring seat flange 21 to form a sealing structure.
[0019] In addition, a pair of hooks 15 are welded on the radial position of the spherical surface of the spherical cover, so as to facilitate the transfer by using a crane or other lifting devices during the test of the machine.
[0020] The steam boiler is controlled by the electric control cabinet. When testing the machine, first install the test cover in place, then increase the temperature and pressure, and then open the solenoid valve. The high-temperature steam flows into the spherical cover 1, and observe the changes in the steam boiler parameters.
