Abstract

The utility model discloses a manual operation actuator which is convenient in manufacture, use and overhauling, the utility model comprises a housing 2, a torsion spring 5, a fastening shaft sleeve 9 and a temperature fuse mechanism, and the torsion spring 5, the fastening shaft sleeve 9 and the temperature fuse mechanism are arranged in the housing. The utility model is characterized in that the inner of the torsion spring 5 is provided with a sleeve shaft 1, a positioning disk 10 is arranged between the upper end of the shaft sleeve 1 and the fastening shaft sleeve 9, a handle 6 is connected with the fastening shaft sleeve 9, a screw 8 which is arranged on the handle 6 can be screwed into any hole of the positioning disk 10, a temperature fuse seat 13 is connected with the housing 2 into integration, and a hook 15 which is hinged together with the positioning disk 10 is hooked on a bracket 19. The utility model has the advantages of small regulating torsion and reliable performance.

Description

Manual actuators

The utility model relates to a kind of actuator, the manual actuators on especially a kind of air conditioner valve that is applied to fire protection requirement.

Present actuator adjusting moment of torsion is big, adjusting function is unreliable, be prone to misoperation, and assembles and overhaul all very inconvenient.

The purpose of this utility model exactly will be for people provide a kind of manufacturing and maintenance extremely convenient, and the manual actuators of dependable performance.

Technical solution of the present utility model is: a kind of manual actuators, it comprises actuator housing 2, is loaded on the torsion spring 5 in the actuator housing 2, fastening axle sleeve 9 and temperature fuse body, it is characterized in that: axle sleeve 1 is housed in the torsion spring 5, between the upper end of axle sleeve 1 and the fastening axle sleeve 9 positioning disk 10 is housed, handle 6 is connected with fastening axle sleeve 9, screw 8 on the handle 6 can be screwed in arbitrary hole on the positioning disk 10, temperature fuse seat 13 links into an integrated entity with actuator housing 2, with hinged hook 15 hooks of positioning disk 10 on support 19.

On the actuator housing wall, the lower end is not hooked on the location-plate 16 in the upper end of described torsion spring 5.

The utility model be with torsion spring upper end not on housing wall, the lower end is hooked on the location-plate, moment of torsion is delivered on the hook by axle sleeve and positioning disk, so plate no longer needs to overcome the moment of torsion of torsion spring when starting tenon; Torsion spring and temperature fuse body all are installed in the actuator housing in addition, therefore are convenient to assembling and maintenance.In sum, the utlity model has and regulate that moment of torsion is little, serviceability is reliable, rational in infrastructure, assemble and overhaul advantage easily.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the C-C view of Fig. 1;

Front view when Fig. 4 is stationary structure for the utility model;

Fig. 5 is the vertical view of Fig. 4.

By Fig. 1,3 find out, torsion spring 5 upper ends are not on housing wall, the lower end is hooked on the location-plate 16, axle sleeve 1 is positioned at wherein and welds together with location-plate 16, the upper end riveted joint of axle sleeve 1 has positioning disk 10, can not rotate mutually after the two riveted joint, and then positioning disk 10 is equipped with fastening axle sleeve 9, fastening axle sleeve 9 welds together with handle 6, locatees with screw 8 between handle 6 and the positioning disk 10, as shown in Figure 2, screw 8 is screwed in the different holes of positioning disk 10, can carry out air quantity and regulate, in addition, temperature fuse seat 13 welds together with actuator housing 2, be convenient to assembling and maintenance, hook 15 is riveted together with positioning disk 10, can rotate mutually after the riveting, and another end hook of hook 15 is on support 19.

During installation, at first valve body output shaft 21 is penetrated in the hole of axle sleeve 1, fastening axle sleeve 9, and actuator housing 2 is fixed on the valve body, with screw 12 tightening valve body output shafts 21, to link up with 15 hooks on support 19, pull the position of handle 6 to " opening ", and as required screw 8 is screwed in arbitrary hole of positioning disk 10, work as breaking out of fire, when flue gas stream reaches uniform temperature, fuse 20 fusing, support 19 moves under the effect of spring 18, and hook 15 is thrown off, and axle sleeve 1 is rotation rapidly under the effect of torsion spring 5, valve is closed the door, and has played anti-fire action.

Shown in Fig. 4,5, also can be with the positioning disk in the utility model 10, fastening axle sleeve 9, screw 8 removes, and becomes adjustable actuator and is fixed actuator, does not promptly carry out air quantity and regulates.
