Abstract
An electric butterfly valve comprises an electric device, a valve body and a normally closed jaw electromagnetic clutch mounted between the head of the valve body and the electric device. The rotation shaft of the valve is connected with the output shaft of the electric device via the normally closed jaw electromagnetic clutch. In the tail part of the valve body are mounted the normally closed jaw electromagnetic clutch, a swing arm, a weight and a brachy axis. The swing arm is connected with the brachy axis and the brachy axis is connected with the rotation shaft of the valve via the normally closed jaw electromagnetic clutch.
Description
Affiliated technical field
The present invention relates to a kind of electric butterfly valve, particularly relate to and a kind ofly when dead electricity, can realize the electric butterfly valve that butterfly valve cuts out.
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 invention provides a kind of dead electricity.
The technical solution adopted for the present invention to solve the technical problems 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 invention has the beneficial effects as follows when electric valve can be implemented in dead electricity to open or close fast system safe.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
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), 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.
Claims (1)
1, a kind of electric butterfly valve, comprise Electric actuator, valve body, it is characterized in that: Normally closed type tooth embedding magnetic clutch is housed between the head of described valve body and the Electric actuator, and the rotating shaft of valve connects by described Normally closed type tooth embedding magnetic clutch with the output shaft of Electric actuator; The afterbody of described 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 described tooth embedding magnetic clutch open in usual with valve hinges.
