Embodiment

[0026] In this embodiment, the material selection and setting details of the combined sealing gasket are described in detail in combination with the requirements of specific working conditions.

[0027] First of all, according to the characteristics of the selected rubber material, the calculation of the size chain of the water inlet cover and the water inlet seat, the optimal thickness of the rubber ring is 1.1mm, and the thickness of the steel ring is 2.8mm, such as image 3 shown.

[0028] Secondly, 8 internal teeth are designed on the inner side of the apron, and the diameter of the internal teeth is calculated to be ￠42 according to the size of the relief groove of the water inlet cover, which prevents it from falling off from the water inlet cover and facilitates maintenance and replacement, such as Figure 4 shown.

[0029] Finally, sand blast the inner surface of the steel ring, and vulcanize the rubber and the inside of the steel ring together in the mold.

Abstract

The invention belongs to the technical field of vehicle cooling systems and particularly relates to a combination type sealing gasket. The problem that an existing expanding water tank sealing gasket can be easily lost, limiting measures do not exist, and excessive compression can be easily caused is solved. The combination type sealing gasket comprises a steel ring and a rubber ring. The rubber ring is embedded on the surface of an inner frame of the steel ring through a vulcanization technology. A plurality of semicircular inner teeth which protrude towards the circle center direction are evenly arranged on the surface of the inner side periphery of the rubber ring. The gasket is designed in an anti-falling mode, and limiting measures are achieved to avoid excessive compression of the rubber ring. Through the technologies of steel ring surface abrasive blasting and rubber material vulcanization, the fact that the vulcanization intensity of the rubber ring and the steel ring is not smaller than 5MPa is guaranteed. In addition, according to the characteristics of selected rubber materials and the size-chain calculation of a water adding opening cover and a water adding opening base, the best thicknesses of the rubber ring and the steel ring are determined, excessive compression of the rubber ring caused by too large force can be avoided during using, so that sealing gasket damage is avoided, and sealing fails in advance is avoided, and the working reliability of a cooling water system is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle cooling systems, and in particular relates to a combined sealing gasket. Background technique [0002] In the vehicle cooling system, the water circulation system is a closed cycle design. The boiling temperature of water in a closed water system can exceed 100°C, usually 105-115°C, up to 125°C. The closed water system increases the temperature difference between the water and the ambient air, thereby reducing the volume of the radiator and reducing the power consumption of the system. For a closed water system with an expansion tank, the highest pressure is located at the upper part of the expansion tank, so the sealing of the water tank cover and the steam air valve is very important to ensure the pressure balance of the water system. Every time the vehicle is trained, it is necessary to check the water level of the car and the car. The frequency of opening and closing of the water filler cap ...
