Valve sealing gasket for new energy automobile cooling system

Abstract

The invention provides a valve sealing gasket for a new energy automobile cooling system. The valve sealing gasket comprises a sealing gasket base body and a PTEF diaphragm framework. A through hole is formed in the middle of the sealing gasket base body in a penetrating mode, the first side face of the sealing gasket base body protrudes outwards to form an inner sealing rib annularly arranged around the through hole, and the second side face of the sealing gasket base body protrudes outwards to form an outer sealing lip annularly arranged around the through hole. The PTEF diaphragm framework is connected with the first side face of the sealing gasket base body and wraps the inner sealing rib. According to the sealing gasket, the rigidity can be effectively reduced, meanwhile, bidirectional self-tightening sealing can be achieved, the sealing effect is guaranteed, meanwhile, the PTEF diaphragm framework wraps the first side face of the sealing gasket base body to make contact with the rotating shaft core, the PTEF diaphragm framework makes direct contact with the rotating shaft core, the abrasion resistance of the sealing gasket is effectively improved, the friction torque is reduced, and the performance requirement of the sealing gasket is met.

Description

technical field [0001] The invention relates to a sealing gasket, in particular to a valve sealing gasket for a cooling system of a new energy vehicle. Background technique [0002] The function of the car cooling system is to take away the heat generated by the engine's combustion, so that the engine can be maintained within the normal operating temperature range. The cooling system is an extremely important part, which is related to the safe operation and service life of the electromechanical devices to be cooled, and is also a weak link that is easily overlooked; and the valve is a very important control unit in the cooling liquid, which can effectively control the cooling liquid. flow switch. There are also certain requirements for sealing in its function. Once leaked, it will lead to overload of the car engine or battery, and thus damage. Therefore, when designing the cooling valve gasket, it is necessary to consider the sealing and meet its auxiliary control function....

AI Technical Summary

Problems solved by technology

There are also certain requirements for sealing in its function. Once leaking, it will cause overload and damage to the car engine or battery. Therefore, when designing the cooling valve gasket, it is necessary to consider the sealing and satisfy its auxiliary control function.

[0003] At present, the valves of the refrigeration system of new energy vehicles have various structures, such as two-way valves, three-way valves, four-way valves and other structures, so the design scheme of the cooling and sealing valve plate is intricate and numerous, such as the use of pure rubber and surface-coated PTEF. , rubber wrapped plastic skeleton and many other methods; Looking at these sealing methods, they are not very ideal in terms of sealing effect, design and processing cost, installation efficiency and sealing durability, and there are certain defects.
