Abstract

The utility model relates to a valve for bicycle inner tube, in particular to a plug-control valve. The plug-control valve for bicycle inner tube mainly adopts a control rod 9 to control a rubber cover stopper 6, and the plug-control valve for bicycle inner tube utilizes inflating pressure and the elasticity of a spring 12 to automatically open and close. The utility model overcomes the shortcoming of the prior art at present, the plug-control valve for bicycle inner tube is without the valve inside and avoids the troubles of infixing the valve inside and often changing rubber. The open and the close of the rubber cover stopper are not easy to abrade. The utility model has the advantages of high durability and convenient installation.

Description

Plug-control valve for bicycle inner tube

The utility model relates to a kind of bicycle inner tube valve, refers more particularly to plug control valve.

Existing bicycle inner tube Valves Technology adopts valve inside to be contained on the valve seat, fastens with clamping nut, is easy to be transferred to by the people.Little rubber on the valve inside damages easily, often changes, and is pretty troublesome.

The purpose of this utility model is to overcome the deficiency of existing bicycle Valves Technology, and a kind of plug control valve of controlling automatically with the valve plug without valve inside is provided.

The utility model can reach by following measure, it is characterized in that: the bottom is provided with a neck in the valve seat, and suitable for reading is garden cylindricality mouth, and up to the seat neck, end opening is a taper mouth.Installing controlling rod in the valve seat, the bar upper end is provided with pole cap, and crown is provided with gas port.The body of rod is inserted in spring, and rivet holder neck under the spring upper ejector pin cap makes controlling rod be subjected to elastic force.The bar lower end is provided with taper leather sheath plug, and the controlling rod that is locked blocks with pad and outer jump ring down.Inner gas pressure passed a seat neck by gas port, and controlling rod is subjected to inner gas pressure thrust or spring force effect to control the leather sheath plug automatically to open or close.

The utility model has following advantage compared to existing technology:

1,, exempts and dialled the trouble of removing valve inside and often changing little rubber without valve inside.

2, the skin plug opens and closes, and is not easy to wear, permanent durable.

3, technology is simple, and is easy to manufacture.

4, length is slightly shorter, easy for installation than existing valve.

The annex explanation: Fig. 1 is the utility model plan view, and Fig. 2 is the utility model sectional view.

Drawing explanation: valve seat 1, valve cap 2, installation screw 3, fastening screw 4, sealing gasket 5, taper leather sheath plug 6, pad 7, foreign minister's spring 8, controlling rod 9, pole cap 10, gas port 11, spring 12, seat neck 13, taper mouth 14, draw-in groove 15.

The utility model further specifies its working principle and embodiment below in conjunction with accompanying drawing.Plug control valve critical component controlling rod 9 is subjected to spring 12 elastic force effects, taper leather sheath plug 6 is drawn fill in valve seat taper mouth 14 sealing valves.There is a cavity valve seat upper body, and inflation enters cavity, and cavity pressure increases, and Pneumatic pipe cleaner is crossed gas port 11 and passed the seat neck, and the valve plug is opened under highpressure promotes, and the chamber internal air pressure reduces, and the valve plug is closed automatically, manually presses lower control arm, and the valve plug is opened, can exhaust.

Embodiment: controlling rod 9 usefulness copper materials are made, and the upper end is pressed into pole cap 10, bore system gas port 11, open draw-in groove 15, overlap upper spring 12(standard piece), the valve seat of packing into refills pick up plug 6(rubber and makes, base angle 43 degree, high 3 millimeters), block down with pad 7 and outer jump ring 8.
