The utility model discloses a heat supply pipeline valve non-section modulation electric actuator which is composed of a shell, a direct current motor, a reduction gear and a digital controller, and the actuator enables the gear to be gradually decelerated and increase torsion by designing different gear ratios of the gear. The rotating speed of 8500-10400 revolutions per minute output by the direct current motor is reduced to about 10 revolutions per minute, the transmission ratio can be increased to more than 4024, the torsion is increased by 20-25% compared with that of an existing actuator, and smooth opening and closing of a heat supply pipeline valve are guaranteed; the digital controller intelligently calculates the rotation angle of the self-control output shaft through big data to drive an external load heat supply pipeline valve to rotate, so that the non-section modulation effect of the valve is achieved; according to actual measurement, the electric actuator can save energy by about 15%, and the electric actuator is a special technology beneficial to the nation and the people.

The utility model provides an intelligent lock motor box which comprises a panel, a box body and a reduction gearbox cover, the design that the panel and a gearbox are integrated is adopted, a speed reducing mechanism of a reduction gearbox can enable an intelligent lock to increase torsion, the effect of large torsion can be achieved through a small motor, and therefore the motor box is small in size and convenient to use. Structures such as a motor circuit are integrated and placed in the motor box, the integration level is high, and installation is convenient; the panel is a highlight panel, the sense of science and technology is high, and the overall appearance is simple and attractive.

The present application relates to a kind of multilayer constant force scroll spring and its production process, including several coil springs;Several described coil springs are successively stacked and are refuted into shape, and the two ends of coil spring are fixed respectively.The beneficial effects of the present application are that:1.thin single-layer coil spring is stacked after forming the constant force scroll spring with consistent bending radius, compared with directly using thicker spring, the forming method of the present application can make the scroll spring curl to small volume more, to realize the increase of its torsion in the case of not increasing or increasing less scroll spring volume, meet the industrial needs;2.the torsion of multiple times after stacking can be obtained after the two ends of single-layer coil spring with consistent inner diameter are fixed respectively, meet the requirement of increasing torsion.

The utility model relates to the technical field of torsion detection, and discloses an insertion barrel torsion detection device which comprises a base, a vertical plate is fixedly connected to the middle of the top face of the base, an inclined plate is fixedly connected to the top of the vertical plate through bolts, a fixing block is fixedly connected to the top face of the inclined plate, and a cushion block is fixedly connected to the top face of the fixing block. A positioning block is fixedly connected to the upper end of the top face of the inclined plate, a front insertion barrel is attached to the inner wall of the positioning block, a notch is formed in the lower end of the front insertion barrel, a rotating air cylinder is fixedly connected to the front side of the top face of the base, a clamping block is fixedly connected to one end of the rotating air cylinder, and a surrounding plate is fixedly connected to the edge of the top face of the base. According to the utility model, the insertion barrel is positioned and fixed by the positioning block, so that the notch is aligned with the clamping block to be clamped, the rotating cylinder is started, the clamping block is rotated, and whether the notch can tolerate enough torsion acting force or not is tested by increasing torsion force.
