Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Mark is as follows among the figure: valve body 1, valve are stifled 2, support 3, gear box 4, lifting screw 5, gear screw rod cover 6, cone pinion 7, transmission shaft 8, spacing collar 9, sealing rubber ring 10, axle sleeve 11, sealing cover 12,13, graphite pads 14,15, pillar 16
Embodiment
Show among the figure that the utility model is stifled 2 by valve body 1, valve, support 3, gear box 4, handle with sleeve are formed.
The two ends of valve body 1 are connected with gas pipe line, and support 3 is fixed in the inner chamber of valve body 1, and gear box 4 is installed on the support 3, in the gear box 4 transmission device is arranged, and an end of transmission device is connected with valve stifled 2, and the other end is connected with handle with sleeve.
Transmission device is made up of lifting screw 5, gear screw rod cover 6, cone pinion 7, transmission shaft 8.Gear box 4 is two body structures up and down, and two bodies are connected by bolton up and down.On support 3, fixedly connected with the central vertical of valve stifled 2 by lifting screw 5 one ends by screw for gear box 4, and the other end passes the gear box wall and enters in gear box 4 cavitys.Gear screw rod cover 6 is positioned at the end of gear box 4 near valve stifled 2, gear screw rod cover 6 is sleeved on the lifting screw 5, internal thread on its inwall is meshed with lifting screw 5, it is circular cone umbrella gear that the gear screw rod overlaps 6 outer rings, it is meshed with cone pinion 7, the central sleeve of cone pinion 7 is contained on the transmission shaft 8, and the outer end of transmission shaft 8 passes the gear box wall and valve body wall is connected with handle with sleeve (handle with sleeve does not draw among the figure), and axle sleeve 11 is arranged outside transmission shaft 8.Between the top of gear screw rod cover 6 and the gear box wall spacing collar 9 is arranged, the two ends of spacing collar 9 contact with the top of gear screw rod cover 6, the lower surface of gear box wall respectively, and the internal diameter of spacing collar 9 matches with the external diameter of lifting screw 5.Gear screw rod cover 6 drives lifting screw 5 when rotating and moves up and down in spacing collar 9.
