[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 The utility model provides a technical solution: a manual and automatic dual-purpose valve control box, including a controller, a starting mechanism, an automatic and manual switching mechanism, an output mechanism and a wiring terminal JX.

[0021] The starting mechanism supplies power to the entire device and starts the entire device to work;

[0022] The controller is used to control the operation and start and stop of each electrical component of the entire device;

[0023] The automatic-manual switching mechanism is used to automatically switch the control mode of the valve control box, so that the valve control box has two control modes;

[0024] The output mechanism is used to determine the output state of the valve control box and enable the valve control box to work normally;

[0025] The connection terminal JX is used to be electrically connected to the valve control box, thereby driving the valve control box to work.

[0026] Among them, when operating the valve control box, both automatic operation and manual operation can be realized, and it can be operated quickly and accurately during the automatic operation and manual operation. The switching method is more convenient. The set starting mechanism can power the entire device, and during the power supply process, the controller can be used to control the automatic-manual switching mechanism and the output mechanism to work, so that the wiring terminal JX can be used to drive the valve control box to work.

[0027] See also Figure 1 The starting mechanism includes a surge and lightning protector SPD, an air switch circuit breaker QF1, an air switch circuit breaker QF2 and a switching power supply DY. The input voltage of the switching power supply DY is 220V and the output voltage is 24V. The controller is connected to the pin of the air switch circuit breaker QF2, the pin of the air switch circuit breaker QF1 is connected to the surge and lightning protector SPD, and the controller is electrically connected to the switching power supply DY.

[0028] Among them, the surge protector SPD set up can limit and filter the voltage and current in the circuit of the electronic components of the entire device. When the circuit is subject to electromagnetic interference such as lightning and surge, the lightning surge protector will automatically start and shunt the excessive voltage and current to the ground wire to protect the electrical equipment from damage. The switch of the set switching power supply DY can power the entire device. The circuit breaker QF1 and the circuit breaker QF2 use ship-type power switches and replaceable fuses.

[0029] See also Figure 1The automatic-manual switching mechanism includes a three-position knob SA, a switch valve SBE, an intermediate relay KA and high and low section contacts of the controller. The three-position knob SA is electrically connected to the starting mechanism, the three-position knob SA is electrically connected to the switch valve SBE, the switch valve SBE is electrically connected to three groups of intermediate relays KA, the three groups of intermediate relays KA are electrically connected to the high and low section contacts of the controller, the model of the three-position knob SA is XB2-BD33, and the model of the switch valve SBE is XB2-BA31.

[0030] Among them, the three-position knob SA and the switch valve SBE cooperate with each other to enable the valve control box to switch between three gears: manual, stop and automatic. When in the manual gear, the switch valve SBE operation is valid, and the automatic signal input is invalid; when set to the stop gear, the switch valve SBE and the automatic signal operation are both invalid; when set to the automatic gear, the automatic signal input is valid, and the switch valve SBE operation is invalid.

[0033] When in use, first of all, when operating the valve control box, both automatic operation and manual operation can be realized, and the operation can be performed quickly and accurately during the automatic operation and manual operation, and the switching method is more convenient. The set starting mechanism can power the entire device, and during the power supply process, the controller can be used to control the automatic manual switching mechanism and the output mechanism to work, so that the wiring terminal JX can be used to drive the valve control box to work. The set surge and lightning protector SPD can limit and filter the voltage and current in the circuit of the electronic components of the entire device. When the circuit is subject to electromagnetic interference such as lightning and surge, the lightning surge protector will automatically start and Excessive voltage and current are shunted to the ground wire to protect electrical equipment from damage, and the switch of the switching power supply DY can supply power to the entire device. The circuit breaker QF1 and the circuit breaker QF2 use ship-type power switches with replaceable fuses.

When in the manual gear, the switch valve SBE operation is effective and the automatic signal input is invalid; when set to the stop gear, the switch valve SBE and the automatic signal operation are both invalid; when set to the automatic gear, the automatic signal input is effective and the switch valve SBE operation is invalid. Such a setting can make the conversion mode faster and more convenient.
