Abstract
The utility model relates to an electrically operated valve actuator, including the casing with set up two control switch and rotatable switch part in the casing, two control switch symmetrical arrangement just are located same height, the switch part has the fan-shaped structure that can touch these two control switch. The utility model discloses control switch to motorised valve executor improves, and rotation through fan-shaped structure realizes opening of control switch and stops, and its switch touches stably, and it is low to handing over installation accuracy requirement moreover, does benefit to and uses in the production, and its yields reaches more than 95%.
Description
Technical Field
The utility model relates to an electrically operated valve executor, in particular to electrically operated valve executor's switch structure and mounting means.
Background
With the rapid development of Chinese economy, the electric valve is used as an actuator of an automatic instrument, the consumption of the electric valve is increased rapidly in recent years, and the localization level is also improved in a leap-type manner. The higher the automation level requirements for the electrically operated valve.
As shown in fig. 1 to 3, the conventional electric valve actuator is configured to toggle a control switch 6 through four protruding points 7 of a switch component 4, so as to achieve opening and closing. In the figure, 1 is a shell, 2 is a support, 3 is a control switch fixing plate, and 5 is a fixing hole. The start and stop of the control switch 6 require that the salient point 7 on the switch part 4 is just matched, the salient point 7 is too high, the switch part 4 is blocked in the rotating process, the salient point 7 is too low, the effect of opening the switch can not be achieved, and the switch part can be frequently disabled due to the fact that the precision in the installation process cannot be guaranteed.
Therefore, the electric valve actuator has inconvenient switch touch, has high requirement on installation precision, is not beneficial to use in production, and has a yield less than 60%.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to overcome among the above-mentioned prior art switch of motorised valve executor and touch inconvenient and the high shortcoming of installation required precision, provide a motorised valve executor that easily touches.
The utility model discloses a solve the technical scheme that above-mentioned technical problem provided and be: the utility model provides an electrically operated valve executor, includes the casing and sets up two control switch and rotatable switch part in the casing which characterized in that: the two control switches are symmetrically arranged and located at the same height, and the switch part is provided with a fan-shaped structure capable of triggering the two control switches.
The utility model discloses control switch to motorised valve executor improves, and rotation through fan-shaped structure realizes opening of control switch and stops, and its switch touches stably, and it is low to handing over installation accuracy requirement moreover, does benefit to and uses in the production, and its yields reaches more than 95%.

Detailed Description
As shown in fig. 4-fig. 4, the electric valve actuator of this embodiment includes a housing 1, a support 2 disposed in the housing 1, a control switch fixing plate 3, and a rotatable switch part 4 (controlled by a driving motor of the electric valve), wherein the control switch fixing plate 3 is provided with a fixing hole 5, and two control switches 6 are fixed on an inner side wall of the control switch fixing plate 3 by screws. As shown in the figure, the two control switches 6 are symmetrically arranged and located at the same height, the switch part 4 is provided with a fan-shaped structure 8 which can trigger the two control switches 6, the contact points of the two control switches 6 are located in the rotation range of the fan-shaped structure 8, and the contact points of the control switches 6 can be pressed in by the outer edge of the corresponding side of the fan-shaped structure.
In the actuator, the start and stop of the control switch 6 are realized by the rotation of the switch part 4. Specifically, the outer edge of the fan-shaped structure 8 of the switch part 4 is pressed to the control switch to enable the control switch to be in an on state, and the control switch on the other side can be turned on by the reverse rotation of the switch part 4.
In the embodiment, the switch is controlled to be started or stopped by the edges of the two sides of the fan-shaped structure of the switch part, and the outer edges of the two sides of the fan-shaped part of the switch part are wider, so that the installation requirements on the control switch and the switch part are not too high.
The utility model discloses a do not confine to above-mentioned each embodiment, all adopt the technical scheme who equates to replace and form, all fall in the utility model discloses the scope of protection that requires.
