Abstract
An electric valve with a feedback indication function comprises an electric actuator, wherein a main transmission shaft is arranged in the electric actuator and is connected with a valve rod on a valve body below the electric actuator; a feedback signal circuit is also arranged in the electric actuator and comprises a common line for inputting voltage, and the common line is respectively connected with an opening signal switch and a closing signal switch; the starting signal switch is connected with a starting indicator light and a starting signal output port; the closing signal switch is connected with a closing indicator light and a closing signal output port.
Description
Technical Field
The utility model relates to an motorised valve technical field especially relates to a motorised valve with feedback instruction function.
Background
The electric valve simply controls the valve by using an electric actuator, thereby realizing the opening and closing of the valve. The electric actuator can be divided into an upper part and a lower part, wherein the upper part is the electric actuator, and the lower part is the valve. The opening/closing state of an electric valve is relatively important information, but a general electric valve has little function of outputting the opening/closing state, and particularly a small-sized electric valve. Thus, a separate device for detecting the opening/closing state of the electric valve must be provided. Therefore, the company designs an electric valve with information for indicating the switch state.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a ball valve seal ring. The technical scheme of the utility model is that: an electric valve with a feedback indication function comprises an electric actuator, wherein a main transmission shaft is arranged in the electric actuator and is connected with a valve rod on a valve body below the electric actuator; a feedback signal circuit is also arranged in the electric actuator and comprises a common line for inputting voltage, and the common line is respectively connected with an opening signal switch and a closing signal switch; the starting signal switch is connected with a starting indicator light and a starting signal output port; the closing signal switch is connected with a closing indicator light and a closing signal output port;
the opening signal switch and the closing signal switch are triggered by the main transmission shaft, and the opening signal switch is closed under the opening state of the valve; the close signal switch is closed when the valve is closed.
In a further improvement, the opening indicator light and the closing indicator light are both positioned at the top of the main transmission shaft, and a transparent plate is arranged on the position, above the opening indicator light and the closing indicator light, of the electric actuator shell.
The utility model has the advantages that:
the utility model discloses set up the circuit of instruction on-off state on the motorised valve, can turn into the state information of opening of motorised valve and send out electrical signal, simplified equipment, reduced the associated equipment investment. The small indicating lamp is arranged on the electric valve, so that the working state of the electric valve can be observed clearly, and the fault state of the electric valve can be judged conveniently.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and together with the description, serve to explain the principles of the invention.
FIG. 1 is a circuit diagram of a feedback signal;
FIG. 2 is a top view of the electric actuator;
fig. 3 is a structural view of a main drive shaft.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1, an electric valve with feedback indication function includes an electric actuator, a main transmission shaft 3 is arranged in the electric actuator, and the main transmission shaft is connected with a valve rod on a lower valve body, and is characterized in that the main transmission shaft is connected with a motor through a gear set, and the electric actuator is provided with a positive interface and a negative interface for providing electric signals to the motor; a feedback signal circuit is further arranged in the electric actuator, as shown in fig. 1: the feedback signal circuit comprises a common line for inputting voltage, and the common line is respectively connected with an opening signal switch and a closing signal switch; the starting signal switch is connected with a starting indicator light and a starting signal output port; the closing signal switch is connected with a closing indicator light and a closing signal output port.
When the switch is used, the public line port is connected with a power supply, and the opening signal output port and the closing signal output port are connected to an external circuit needing to receive signals. The opening signal switch and the closing signal switch are triggered by the main transmission shaft 3. When the valve is opened, the main transmission shaft triggers the opening signal switch S1 to be closed, at the moment, the green light L1 is lightened, and the opening signal output port outputs an opening electric signal outwards; when the main transmission shaft triggers the closing signal switch S2 to close in the valve closing state, the red light L2 is lighted, and the closing signal output port outputs an electric signal in the closing state outwards.
As shown in fig. 2, the start indicator light and the stop indicator light are both located at the top of the main transmission shaft, and a transparent plate 2 is arranged on the electric actuator casing 1 above the start indicator light and the stop indicator light, so that the red light and the green light can be directly observed.
The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
