Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guide rings, in particular to a heat-insulating phenolic cloth-reinforced guide ring. Background Art
[0002] Phenolic cloth guide ring is a sealing element commonly used in high temperature and high pressure environments. It is mainly composed of phenolic resin and cloth. Phenolic resin has excellent high temperature resistance, corrosion resistance and high mechanical strength, while the cloth provides good elasticity and softness. This guide ring can maintain stable working performance under high temperature and high pressure conditions, avoiding sealing failure caused by temperature and pressure changes.
[0003] The traditional phenolic cloth guide ring is a high temperature and corrosion resistant sealing element, usually made of phenolic resin and cloth. During use, it is first necessary to select the appropriate phenolic cloth guide ring material according to the specific working conditions of the equipment, such as temperature, pressure and chemical media, to ensure its stability and durability under high temperature and high pressure environments. During installation, the guide ring needs to be correctly placed in the sealing part, usually around the rotating parts of the pump, valve or other fluid control equipment to guide the fluid flow and prevent leakage.
[0004] The above-mentioned traditional phenolic cloth-stuck guide ring is usually made of phenolic resin. Although it is resistant to high temperatures, its thermal conductivity is relatively high, which means that it has poor performance in terms of thermal insulation. The cloth-stuck structure will shrink or expand at high temperatures, resulting in a decrease in sealing performance or structural deformation, which in turn affects the thermal insulation effect. Utility Model Content
[0005] In order to make up for the above shortcomings, the utility model provides a heat-insulating phenolic cloth-insulated guide ring, which aims to improve the poor heat-insulating performance of traditional phenolic cloth-insulated guide rings. The cloth-insulated structure will shrink or expand at high temperatures, resulting in reduced sealing performance or structural deformation, thereby affecting the heat-insulating effect.

[0007] Furthermore, the thermal insulation component includes an aluminum oxide layer 1, which is arranged inside the thermal insulation layer. The inner wall of the guide ring body is fixedly connected with a bonding plate, and the bonding plate is made of glass fiber cloth.
[0008] Furthermore, the outer wall of the guide ring body is evenly coated with a ceramic coating, and a glass fiber layer is arranged inside the guide ring body.
[0009] Furthermore, a high-performance fiber layer is disposed on one side of the glass fiber layer, and the high-performance fiber layer is disposed inside the guide ring body.
[0010] Furthermore, an elastic body 1 is fixedly connected to the interior of the guide ring body, and an elastic body 2 is fixedly connected to the interior of the guide ring body.
[0011] Furthermore, the elastic body 1 and the elastic body 2 are arranged in a staggered manner, and the outer walls of the elastic body 1 and the elastic body 2 are both arranged inside the glass fiber layer and the high-performance fiber layer.
[0012] Furthermore, a reinforcement layer is provided inside the guide ring body, and a second ceramic coating is evenly coated on the outer wall of the reinforcement layer.
[0013] Furthermore, the reinforcement layer is made of stainless steel material, and a glass fiber reinforced composite layer is arranged inside the reinforcement layer.
[0014] The utility model has the following beneficial effects:
[0015] 1. In the utility model, preliminary heat insulation is first performed through the heat insulation layer and the interior, and then part of the heat is dispersed in combination with the boron nitride layer, the metal layer and the heat dissipation holes. Finally, the aluminum oxide layer and the bonding plate between the guide ring body and the heat insulation layer are used for further heat insulation. The poor heat insulation performance of the guide ring, which leads to a decrease in sealing performance or structural deformation, and further affects the heat insulation effect, is solved. Efficient heat insulation is achieved, which can help reduce heat loss during mechanical movement, thereby improving energy efficiency and equipment performance.
[0016] 2. In the utility model, the strength of the guide ring body is firstly improved by the glass fiber layer and the high-performance fiber layer inside the guide ring body, and then the flexibility is improved by the elastomer 1 and the elastomer 2, and then the corrosion resistance is improved by the reinforcement layer and the ceramic coating 2, thereby achieving effective compressive flexibility and corrosion resistance, which can ensure that the equipment maintains stable performance in complex environments, reduce the failure rate, and improve overall reliability.

[0026] Specifically, first, the inner wall of the thermal insulation layer 2 is bonded to the workpiece, and preliminary thermal insulation is performed through the aluminum oxide layer 1 201. At this time, a small amount of heat will enter the interior of the thermal insulation layer 2, and then the heat is dispersed through the boron nitride layer 202 and the metal layer 203.
