Description

Technical Field

[0001] The present invention belongs to the technical field of electric valves, and particularly relates to an electric valve and its application. Background Art

[0002] An electric valve is a common mechanical structure. An electric valve uses an electric actuator to control a valve, which can be used to open and close the valve. Generally, an electric valve is composed of upper and lower parts. An electric valve is a high-end product among automatic control valves. It can

[0003] not only achieve the switching function, but also a regulating electric valve can achieve the valve position regulation function.

[0004] In existing electric valve design solutions, for example, in the existing patent technologies CN201821393160.7 and CN201720523339.9, a driver is used to drive a coupling, and then the coupling is used to drive the valve shaft to rotate, thereby realizing the actuator action switching for opening and closing each branch valve. However, this design has various defects. One is that the outer shell and internal space of the entire electric valve need to reserve sufficient vertical height to accommodate the coupling, so the height of the entire valve shell is relatively high. In addition, a control system is installed in the current electric valve, but the installation of the control system is complex, the process of the coupling is difficult, the processing cost is high. At the same time, the current electric valve cannot start the irrigation groups in turn according to the set time to implement irrigation operations, cannot set the water volume per mu in the electric valve, cannot perform intelligent operations, has poor use effects and low intelligence level. In addition, a spherical body is generally used as the switching medium for multiple channels in the existing multi-way opening electric valves, but this spherical body design is prone to uneven friction force, large friction force, heat generation on the contact surface, and is more unfavorable for lubrication. To solve this problem, there is an urgent need for an electric valve. Summary of the Invention

[0005] The purpose of the present invention is to propose an electric valve and its application to solve the problems that a control system is installed in the current electric valve, but the installation of the control system is complex, the process of the coupling is difficult, the processing cost is high. At the same time, the current electric valve cannot start the irrigation groups in turn according to the set time to implement irrigation operations, cannot set the water volume per mu in the electric valve, cannot perform intelligent operations, has poor use effects and low intelligence level, and the friction force of the spherical valve body is unstable.

[0006] To achieve the above purpose, the present invention adopts the following technical scheme: An electric valve includes a valve shell. An antenna is arranged at the top of the valve shell, a bottom mounting part is arranged at the bottom of the valve shell, a valve switch is arranged on one outer wall of the valve shell, a photovoltaic panel is arranged on the top surface of the valve shell. Four valve switches are regularly arranged at equal intervals on the same straight line, and an emergency stop button is arranged on the other outer wall of the valve shell;

[0007] A bottom case is provided on the bottom surface of the valve housing. A servo motor is fixedly installed at the top of the bottom case. One end of the output shaft of the servo motor is fixedly installed with a mounting disc through a rotating shaft. A mounting seat is fixedly installed on the top surface of the mounting disc through a connector. A driving plate is fixedly installed on the top surface of the mounting seat through a connecting frame. A limiting plate is provided at the top of the driving plate through a connecting column. The actuator and the valve shaft are directly connected with a unified structural design. The corresponding water outlets of the valve shaft for the electric valve are spherical bodies, and the spherical surface process of the spherical bodies adopts surface coating treatment. A battery panel is also included, and the driving plate and the battery panel are integrally designed.

[0011] One end of the output shaft of the servo motor is fixedly installed with a mounting disc through a rotating shaft, and a mounting seat is fixedly installed on the top surface of the mounting disc through a connector.

[0012] As a further description of the above technical solution:

[0013] A built-in battery is provided at the top of the mounting seat.

[0014] As a further description of the above technical solution:

[0015] A limiting plate is provided at the top of the driving plate through a connecting column, and a communication board is fixedly installed above the limiting plate through a connecting column.

[0016] As a further description of the above technical solution:

[0017] The surface area of the driving plate is larger than the surface area of the communication board, and the surface area of the communication board is larger than the surface area of the battery panel.

[0018] The present invention also discloses a method for applying an electric valve, including the following steps:

[0019] S1. Before using the electric valve, install the electric valve to a designated area through the bottom mounting member, and fixedly connect the electric valve with the mounting structure through screws;

[0020] S2. When in use, set the duration of the electric valve, and the system starts the irrigation groups in turn according to the set time to implement irrigation operations;

[0021] S3. When there is sufficient sunlight in the external environment, the sunlight will be fully collected by the photovoltaic panel, and after being collected, it will be converted into electric energy and stored in the built-in battery for use;

[0022] S4. Set the water volume per mu in the electric valve. The system automatically implements irrigation operations in combination with a flow meter. When the water volume reaches the set value, the system automatically switches to the next group.

[0023] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0024] 1. In the present invention, a photovoltaic panel is provided outside.

The system automatically implements irrigation operations in combination with a flow meter. When the water volume reaches the set value, the system automatically switches to the next group. It has good use effects and high intelligence.

[0025] 2. Since the limit plate in the device is placed in the space originally occupied by the coupling, the internal space of the valve housing is increased. The battery panel and the drive panel are integrated, effectively reducing the overall height of the device. The actuator and the valve shaft have a unified structure, greatly reducing the coupling cost.

[0026] 3. The spherical surface process with surface coating treatment enables the existing plastic valve shaft to maintain light weight and corrosion resistance while greatly reducing the static friction force, so that the torque driving force changes uniformly and linearly during the rotation and switching of the water outlet directions of the electric valve shaft without sudden jamming.
