Technical Field
The utility model relates to the technical field of valve cover nuts of automobile air conditioner pipes, in particular to a maintenance-free automobile refrigerant quantity observer.
Background
The valve cap has the functions of isolating air, avoiding dust, water, oil and the like from damaging the valve core sealing rubber, prolonging the service cycle of the valve core, and if the valve cap is not arranged for a long time, the valve core is very easy to damage, and the slow air leakage phenomenon of the tire is influenced, but the valve cap is also required to be taken into consideration, and the valve core can be damaged only by screwing the valve cap to a degree of slightly resistance.
The key point is that the valve cap can isolate air, so that the damage of dust, water, oil and the like to the valve core sealing rubber is avoided, and the service cycle of the valve core is prolonged. If there is no valve cap for a long period of time, the valve core is very easily damaged.
The inflating valve acts to inflate and deflate the tire and maintain the seal after inflation of the tire. The common inflating valve consists of an inflating valve body, a valve core and 3 key parts of an inflating valve cap. If the valve cap is not perceived to be unscrewed when the tire is to be inflated, then the process is required to be carried out at a repair shop, and if it is to be done by oneself, a skilled level of skill is required to avoid damaging the valve core, which often occurs on metal valves.
The existing automobile valve race has a simple overall structure, only has a simple effect of sealing the gas in the automobile, and cannot read the numerical value. Meanwhile, the valve plug is made of plastic materials, and is easy to damage.
Therefore, a structure is urgently needed to solve the above-mentioned problems.
