Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Handlebar 1-2 upper end is threaded end and the interior handle 1 that is threaded into integral body of bulb 1-1, and handlebar 1-2 is hinged on bearing pin 2-1 between two transverse arms of bonnet 2, and the clamping of handlebar lower ending opening is engaged on the axle 3-1 that is horizontally through opening clevis 3.
15 4 jiaos of setting sleeves have mounting hole, and there is step-shaped blind hole the centre.
Before the valve body 4, gas delivery port A is arranged respectively on the rear sidewall, B and relief opening R1, R2, suction port P, and communicate with valve pocket respectively, before, on four jiaos of the ear end faces installation screw is arranged, on, lower surface has mounting hole, drive fit has columnar valve pocket 5 in the intermediate throughholes, valve pocket 5 outer surfaces axially have uniform, the five road grooves at interval and six seal grooves, uniform identical small through hole is arranged on the per pass groove periphery, A on the corresponding valve body of described small through hole difference, B, R1, R2, the P hole, the corresponding large large O RunddichtringO 7 of diameter of installing of seal groove makes 4 sealings of valve pocket 5 and valve body.
Valve rod 6,6 ' with the total length of valve body 4 and setting sleeve 15 coupling, be equipped with on the valve rod six little O RunddichtringOs 8 or six little O RunddichtringOs 8 ', 8, make valve rod 6,6 ' and 5 sealings of valve pocket, the circular groove that two two ends band conical surfaces are arranged on the valve rod intermediate section is air flue 6-1,6 '-1, two symmetrical ring groove 6-2 make 6 '-2 positions into and let out state in becoming in the middle of the valve rod 6,6 ' only be, install the little O RunddichtringO 8 identical with little O RunddichtringO 8 ', also only be that the position is different.
The circular arc notch 6-3,6 '-3 that cooperates with steel ball 9 is arranged in the middle of valve rod 6, the 6 ' both ends of the surface.
Positioning shaft 10 is stepped stem, inside and outside position limit cycle 11,13 is installed on it, cover has spring 12 on inside and outside position limit cycle 11,13 the positioning shaft, in the groove that outer position limit cycle 13 embeds collar 14 is installed also, make the part of installing on the positioning shaft can not carry out spacing by axial float, there is blind hole the centre of the positioning shaft the other end, and blind orifice end 10-1 is tubaeform, as shown in Figure 9.
