Automobile tire valve nozzle, knowledge introduction

We all know that tires are important for a car, but for a tire, did you know that the small valve also plays an important role?  

The function of thevalve is to charge and deflate the tire of a small part, and maintain the tire after the air seal.  The common valve is composed of valve body, valve core and valve cap.         Then the next xiaobian will give you a detailed   introduction to the car tire valve  

 Types of valves:  

 1, according to the use: bicycle valve, motorcycle, electric car valve, car valve, truck bus valve, agricultural engineering  vehicle valve, special valve, etc.  

 2. According to whether there is an inner tube, there are tube valve and tubeless valve.  

 3, according to the way of assembly: screw-on universal valve , clamp-in valve and snap-in valve.  

 4. According to the size of core chamber, it can be divided into ordinary core chamber valve and large core chamber  valve.  

5, according to the valve core: English Dunlop/Woods valve, American Schrader valve, French presta valve, German  mouth and Italian mouth.  

 Valve structure:  

The valve body (base) is the only way for gas to enter the tire, and it also contains and protects the valve core;  Fastening nut from the name know that its role is to make the valve nozzle and   the wheel ring fixed more stable; Two gaskets of different materials are used to fasten the nut.  The rubber sealing gasket plays the duty of sealing and preventing air leakage in the inner part of the wheel ring;  The often lost valve cap can avoid the intrusion of foreign bodies on the valve, while achieving the secondary sealing of the valve;  While the valve core ensures the smooth injection of gas into the tire, it also has the function of preventing gas leakage.  

 Valve installation  

 The assembly of valve nozzle can be divided into screw assembly type, compression type and buckle type.  For example, the assembly of the rubber valve is buckle type, and the valve base is  equipped with a slot to fix it with the ring, which   also leads to its one-time use, once removed, it can not be used again.  And the metal valve uses screw assembly, using gaskets and fastening nuts to fix the valve, can be reused after removal.
