Abstract
The electric butterfly valve that the utility model provides a kind of metallurgy, nuclear power industry to use, comprise Electric actuator, valve body, Normally closed type tooth embedding magnetic clutch is housed between the head of valve body and the Electric actuator, and the rotating shaft of valve connects by Normally closed type tooth embedding magnetic clutch with the output shaft of Electric actuator; The afterbody of valve body is equipped with tooth embedding magnetic clutch open in usual, swing arm, weight and minor axis, and swing arm is connected by key with minor axis, and minor axis connects by tooth embedding magnetic clutch open in usual with valve hinges.The beneficial effects of the utility model are that electric valve opens or closes can be implemented in dead electricity the time fast, and are simple in structure, system safe.
Description
Affiliated technical field
The utility model relates to a kind of electric butterfly valve, particularly relates to a kind ofly can realizing the electric butterfly valve that butterfly valve cuts out or opens when dead electricity.
Background technique
The present use at electric butterfly valve metallurgical, that nuclear power industry is used, owing to the auto-lock function of Electric actuator, valve can only be in residing position when cutting off the power supply when system's dead electricity.Realize that valve closes or open when dead electricity, can only adopt band spring reset formula single-acting Pneumatic actuator.
Summary of the invention
In order to overcome the deficiency that existing electric butterfly valve can not cut out voluntarily or open when the dead electricity, the electric butterfly valve that can close or open when the utility model provides a kind of dead electricity.
The technological scheme that its technical problem that solves the utility model adopts is a kind of electric butterfly valve, comprise Electric actuator, valve body, Normally closed type tooth embedding magnetic clutch is housed between the head of valve body and the Electric actuator, and the rotating shaft of valve connects by Normally closed type tooth embedding magnetic clutch with the output shaft of Electric actuator; The afterbody of valve body is equipped with tooth embedding magnetic clutch open in usual, swing arm, weight and minor axis, and swing arm is connected by key with minor axis, and minor axis connects by tooth embedding magnetic clutch open in usual with valve hinges.
The beneficial effects of the utility model are that electric valve opens or closes can be implemented in dead electricity the time fast, and are simple in structure, system safe.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 embodiment's sectional view.
Among the figure: 1. Electric actuator; 2. output shaft; 3. Normally closed type tooth embedding magnetic clutch; 4. valve hinges; 5. valve body; 6. tooth embedding magnetic clutch open in usual; 7. minor axis; 8. swing arm; 9. weight.
Embodiment
As shown in Figure 1, a kind of electric butterfly valve, comprise Electric actuator 1, valve body 5, Normally closed type tooth embedding magnetic clutch 3 is housed between the head of valve body 5 and the Electric actuator 1, valve hinges 4 connects by Normally closed type tooth embedding magnetic clutch 3 with the output shaft 2 of Electric actuator 1; The afterbody of valve body 5 is equipped with tooth embedding magnetic clutch 6 open in usual, swing arm 8, weight 9 and minor axis 7, and swing arm 8 and minor axis 7 are connected by key, and minor axis 7 connects 6 with valve hinges 4 by tooth embedding magnetic clutch open in usual.During normal state, Normally closed type tooth embedding magnetic clutch 3 be in electricity condition, the output shaft 2 of Electric actuator 1 is in coupled situation with valve hinges 4; Tooth embedding magnetic clutch 6 open in usual be in electricity condition, function such as weight 8, swing arm 9 is in disengaged condition with valve hinges 4, and this moment, weight 8 swing arms 9 were lifted, and valve can realize open and close under the driving of Electric actuator 1, stop.Under systematic failures (dead electricity) state, Normally closed type tooth embedding magnetic clutch 3 dead electricity, the output shaft of Electric actuator 1 and valve hinges 4 are in disengaged condition; Tooth embedding magnetic clutch 6 open in usual is in power failure state, and weight swinging arm device and valve hinges 4 are in coupled situation, but valve quick closedown or open under the effect of the potential energy of weight swinging arm device.
