First, the valve overview:The function of the valve is to inflate and deflate the tire and maintain the seal after the tire is inflated. The ordinary valve is composed of three main parts: the valve body, the valve core and the valve cap.
Second, the valve function:A one-way valve (check valve) used to inflate and discharge gas or liquid in tires, and can maintain and detect internal pressure.
Tube tires are mounted on the inner tube, and tubeless tires are mounted on the rim.
Three, valve classification:
There are many ways to classify tire valves, which are roughly as follows
1. According to the use classification:
Driving valve, motorcycle, electric vehicle valve, car valve, truck bus valve, agricultural engineering vehicle valve, special valve, etc.
2. Classification according to the presence or absence of inner tube:
Tube valve tube valve and tubeless valve tubeless valve
3. Classification by assembly method:
Screw-on valve screw-on universal valve, compression valve clamp-in valve and snap-on valve snap-in valve.
4. According to the size of the core cavity:
Ordinary core chamber valve and large core chamber valve.
5. According to valve core classification:
British mouth dunlop/woods valve, American mouth Schrader valve, French mouth presta valve, German mouth and Italian mouth tire valve can be divided into rubber metal valve and metal valve with rubber pad according to their structure. The former is used for car tire inner tubes, while the latter is mainly used for heavy duty tire inner tubes. The internal structure of a tubeless tire valve is the same as a normal valve.
4. How to use the drilling power head to process the fine holes of the valve core, and what are the technical requirements for processing the extremely fine holes with the spindle power head?
1. The vent hole of the valve core is processed by the BINDE tapping and drilling power head, which has a good surface finish. Thanks to the stable dual-servo drilling and tapping control program, the stable and adjustable spindle drilling speed can be very It is suitable for the surface finish of the valve core brass material.
2. Consistent and stable valve core air hole concentricity, the accuracy of the platform fixture feeding mechanism is used to ensure that there is almost no displacement error in the position of the spindle tapping power head, which can ensure that the valve core hole concentricity when the product is drilling and tapping is consistent and stable. high characteristic.
3. High efficiency, high flexibility,Drilling and tapping power headIn the dual-servo tapping control program, detailed parameters such as spindle speed, feed speed, and drilling size can be set in the program. There is no need to replace other accessories. The program setting can perfectly realize the valve core air hole drilling of various specifications. Hole machining parameters.
