Description

Electric valve

The utility model belongs to the technical field of valves, in particular to an electric ball valve for automatically controlling liquid flow.

Existing valves for automatic control of liquid flow generally use solenoid valves. Solenoid valves use electromagnetic principles and the pressure characteristics of liquids to control the opening and closing of valves to realize the working process of automatic water intake and water cutoff. Due to the limitation of the design and working principle, the diameter of the existing various solenoid valves cannot be consistent with the diameter of the pipe diameter, which leads to a large loss of flow in use; in use, the existing various solenoid valves are The liquid to control the flow rate has high requirements. When the liquid is turbid, sticky or has small debris, it cannot work; in use, the existing various solenoid valves have certain requirements for water pressure. When the water pressure is small Just can't work; In addition, existing various electromagnetic valves consume a lot of power when working, the electromagnetic coils are easy to age, and have a short service life.

The task of the utility model is to provide a solenoid valve with energy saving, long service life, low requirements on the liquid controlled flow, and no loss of flow during use. Electric ball valve for automatic control of liquid flow.

The task of the utility model is accomplished in the following manner: the electric ball valve includes a motor (1), a micro switch (2), a connecting pipe (4), a bracket (5), a valve body (6), a cam (9), a ball valve (11). The motor (1), micro switch (2) and valve body (6) are fixed on the bracket (5), and the cam (9) and one end of the connecting pipe (4) are fixed on the motor output shaft (14) of the motor (1) in turn. ), where the micro switch (2) is matched with the cam (9). The other end of connecting pipe (4) is fixed on the ball valve (11) in the valve body through hole (12) that is located at valve body (6), has ball valve through hole (13) on ball valve (11). During use, electric ball valve of the present utility model is contained on the pipeline that needs automatic control liquid flow, and electric wire is connected on the motor (1) and micro switch (2) of electric ball valve of the present utility model. When the power is turned on, the motor (1) works and drives the cam (9) to rotate through the motor output shaft (14). At the same time, the ball valve (11) is driven to rotate through the motor output shaft (14) and the connecting pipe (4). When the ball valve through hole (13) on the ball valve (11) was in communication with the valve body through hole (12) on the valve body (6), the liquid could pass through the valve body through hole (12) on the valve body (6). ), the bump on the cam (9) contacts the switch button on the micro switch (2), the micro switch (2) is in the closed state, the motor (1) stops rotating, and the electric ball valve is in the open state. When the electric wire is powered on again, the motor (1) starts to work again, and drives the ball valve (11) to rotate through the motor output shaft (14) and the connecting pipe (4). When the ball valve through hole (13) on the ball valve (11) When the valve body through holes (12) on the valve body (6) are mutually closed, the convex point on the cam (9) contacts the switch button on the micro switch (2) again, and the micro switch (2) is closed again. state, the motor (1) stops rotating, and the electric ball valve is in the closed state.

Compared with the existing solenoid valve, the utility model has the characteristics of low cost, low power consumption, long service life and low requirement for the liquid with controlled flow. The utility model is suitable as various valves for automatically controlling liquid flow.
