Description

Technical Field

[0002] In modern industrial production and building equipment automation control systems, two-way valves are widely used to regulate the on / off state and flow rate of fluids. For example, in central air conditioning systems, the flow of chilled water or hot water is regulated by controlling the opening and closing of two-way valves, thereby controlling the indoor temperature. In industrial automated production lines, two-way valves are used to control the delivery of various process fluids to ensure the stable operation of the production process.

[0059] The upper end of the electromagnetic push rod 5 is inserted into the through hole 30 on the cam 3, and the lower end of the electromagnetic push rod 5 is arranged at the center position of the control circuit board 6 and aligned with the travel switch 19; the valve assembly includes a valve body 01, a valve 02 arranged in the valve body 01, and a valve core 03 arranged on the valve 02; the swing arm 16 includes a first working position and a second working position, and the electromagnetic push rod 5 includes a third working position and a fourth working position;

Specifically, when the two-way valve is required to be opened, the energy storage circuit 20 outputs an on signal to the socket 17, the on signal is powered, the motor 11 is powered through the normally open contact of the travel switch 19 (at this time, the contact is closed by the rebound compression of the spring 52 in the electromagnetic push rod 5), the motor 11 rotates, the swing arm 16 is driven to rotate in the first direction X, that is, the counterclockwise direction through the gear 04, the swing arm 16 presses the valve core 03, the valve core 03 moves downward, and the valve 02 is opened (at this time, the valve is in the Figure 4 and Figure 5 open state).

[0084] In some embodiments, as shown in FIG. 2, the energy storage circuit 20 comprises a first power conversion module 33, a second power conversion module 23, a boost module 31, an inverter module 32, a first relay coil 35, a second relay coil 29, and a farad capacitor 30. Figure 6 and Figure 10As shown, the energy storage circuit 20 further comprises a first diode 26 connected between the first end F1 of the first relay coil 35 and the normally open contact 271 of the second relay coil 29.

[0085] In some embodiments, as shown in Figure 6 and Figure 10 As shown, the energy storage circuit 20 further comprises a second impedance element 34, a second diode 24 and a third diode 25; the first end of the second impedance element 34 is connected in series between the first output end B11 of the second power conversion module 23 and the first end of the second diode 24, and the second end of the second impedance element 34 is connected to the first end M1 of the second relay coil 29; the second end of the second diode 24 is connected to the first end of the third diode 25, and the second end of the third diode 25 is connected to the first end C1 of the farad capacitor 30 and the normally closed contact 272 of the second relay coil 29, respectively.

[0086] The first power conversion module 33 can be a 220VAC to 15VDC power module, the second power conversion module 23 can be a 220VAC to 15VDC power module (constant voltage and constant current), the boost module 31 can be a 3-19V to 12V wide voltage module, the inverter module 32 can be a 12VDC to 220VAC sine wave inverter, and the second impedance element 34 can be a current-limiting variable resistor.

[0087] Specifically, as shown in Figure 10 The 220VAC two-wire open signal is input to the first power conversion module 33, and the first power conversion module 33 generates a 15VDC power supply to power the first relay coil 35. When the first relay coil 35 is powered, the normally open contact 281 of the first relay coil 35 is closed, and the normally closed contact 282 is opened. The second power conversion module 23 has a constant voltage and constant current charging function, which meets the charging characteristic requirements of the farad capacitor 30 for initial constant current and later constant voltage. The 220VAC two-wire open signal is input to the second power conversion module 23, and the second power conversion module 23 outputs a 15V power supply to power the second relay coil 29, causing the normally open contact 271 to close and the normally closed contact 272 to open. The 15VDC power supply of the second power conversion module 23 is stepped down to about 13.5V through the second diode 24 and the third diode 25 to charge the farad capacitor 30.

[0088] When the second relay coil 29 is not attracted, the 15VDC from the first power conversion module 33 cannot be output to the boost module 31. The 15VDC from the second power conversion module 23 charges the farad capacitor 30, and at the same time, supplies power to the second relay coil 29 through the second impedance element 34. Due to the effect of the second impedance element 34, the voltage at point a is low at the initial stage of charging, and the current of the second relay coil 29 is very small, so the second relay coil 29 cannot be attracted. As the farad capacitor 30 stores more electricity, the voltage at point a gradually rises, and when it reaches the rated starting voltage of the second relay coil 29 (for example, > 3.5V), the second relay coil 29 can be attracted. By adjusting the second impedance element 34, the starting point of the attraction of the second relay coil 29 can be adjusted.

[0089] In this stage, the second impedance element 34 is a variable resistor. When the variable resistor increases, the attraction of the second relay coil 29 is delayed. When the variable resistor decreases, the attraction of the second relay coil 29 is advanced. This stage is the pre-charging stage of the farad capacitor 30, which alleviates the problem of insufficient charging of the farad capacitor 30 caused by the power-off immediately after the power-on of the device. Generally, adjusting the variable resistor can make the farad capacitor 30 be charged to more than 10V when the second relay coil 29 is attracted, and the normally open contact 271 of the second relay coil 29 is closed. The 15VDC from the first power conversion module 33 supplies power to the boost module 31 through the first diode 26 and the normally open contact 271, and then provides 220VAC power through the inverter module 32 and the normally open contact 281 and the normally closed contact 282 of the first relay coil 35, to obtain 220VAC on and off signals.

[0090] Specifically, when the two-wire opening signal 220VAC input is provided, the second power conversion module 23 is powered, at this time, since the Faraday capacitor 30 has a low capacitance, the voltage at point a is low, and thus the second relay coil 29 cannot be attracted. The first power conversion module 33 performs constant current pre-charging for the Faraday capacitor 30 through the second diode 24 and the third diode 25. When the capacitance of the Faraday capacitor 30 increases (about 85% of the capacitance), the voltage at point a gradually increases to a certain value, the second relay coil 29 obtains sufficient current to be attracted, and the normally open contact 271 is closed. The first power conversion module 33 supplies power to the voltage boosting module 31 through the first diode 26 and the normally open contact 271, and the voltage boosting module 31 provides a 12VDC stable power supply for the inverter module 32. When the two-wire opening signal still has a 220VAC input, the first relay coil 35 is attracted, the normally open contact 281 is closed, the inverter module 32 outputs a 220VAC power supply through the normally open contact 281 to supply power to the motor 11, and the valve of the two-way valve starts to open. When the two-way valve is fully opened, the motor 11 current is cut off by the travel switch 19 of the mechanical non-return assembly as described in the above embodiment, and the valve 02 is ensured to be opened without rebounding by the cam 3 of the mechanical non-return assembly.

[0091] The Faraday capacitor 30 is charged for about 1 minute, and the charging amount reaches more than 85%. If the two-wire opening signal does not have a 220VAC input, that is, a valve closing signal is sent or the equipment is powered off. At this time, the first power conversion module 33 is immediately powered off, the first relay coil 35 is powered off, the normally open contact 281 is opened, and the normally closed contact 282 is closed. The Faraday capacitor 30 supplies power to the voltage boosting module 31 through the normally closed contact 272, the voltage boosting module 31 outputs a 12VDC power supply, and provides a 12VDC short-term stable power supply for the inverter module 32. The inverter module 32 outputs a 220VAC power supply, and outputs a 220VAC closing signal through the normally closed contact 282. The closing signal provides a closing signal for the two-way valve, and promotes the two-way valve to close. The electromagnetic push rod 5 is started and moved downward, the cam 3 is moved downward, the swing arm 16 of the two-way valve is rebounded by the force of the valve core 03, and the two-way valve is closed and reset. As the storage of the Faraday capacitor 30 decreases, after about 1 minute, the voltage boosting module 31 stops outputting, and finally the inverter module 32 stops outputting a 220VAC power supply, the closing signal is powered off, and the closing signal of the two-way valve is stopped. Thus, the functions of powering off the motor 11 after the valve is closed and ensuring the valve 02 to be reset after the power is off are realized.

[0092] It should be noted that, Figure 10 The two-way valve is a two-wire valve (220VAC opening signal).

After the inverter module 32, the normally open contact 281 and the normally closed contact 282 output the two-way valve open / close signal. The functions of opening the valve, closing the valve and resetting the valve after power failure are realized. Among them, the functions of valve opening and power failure and valve closing and power failure rely on the original three-wire system two-way valve.

[0096] As shown in Figure 12 , the working principle in the Figure 12 is similar to the working principle in the Figure 11 . Specifically, the two-wire system open signal input 220VAC is converted by the first power conversion module 33, the first relay coil 35 is attracted, the normally open contact 281 is closed, and the normally closed contact 282 is opened. The farad capacitor 30 is charged by the second power conversion module 23, and when the farad capacitor 30 is charged more than 85%, the second relay coil 29 is attracted, the normally open contact 271 is closed, and the first power conversion module 33 is allowed to supply power to the boost module 31. Figure 12 In the Figure 11 , the inverter module 32 in the is removed, and the 12VDC power supply outputs the two-way valve open / close signal through the normally open contact 281 and the normally closed contact 282 of the first relay coil 35. The functions of opening the valve, closing the valve and resetting the valve after power failure are realized. Among them, the functions of valve opening and power failure and valve closing and power failure rely on the original three-wire system two-way valve.

It should be noted that the three-wire system (220VAC open / close signal) is changed into a three-wire system two-way valve (12VDC open / close signal).

[0098] As Figure 13 shown, Figure 13 the working principle in Figure 12 is similar. Specifically, the off signal is not connected, the three-wire opening signal input 220VAC, through the first power conversion module 33 to start the first relay coil 35 suction, normally open contact 281 closed, normally closed contact 282 open. Through the second power conversion module 23 to charge the farad capacitor 30, when the farad capacitor 30 charge more than 85%, the second relay coil 29 suction, normally open contact 271 closed, allowing the first power conversion module 33 for the boost module 31 power supply, Figure 13 in Figure 11 also remove inversion module 32, 12VDC power through the first relay coil 35, normally open contact 281, normally closed contact 282 output two-way valve open, off signal. Realize the valve opening, valve and power off after the valve reset function. Among them, the valve open power off and the valve off power off function depends on the original three-wire two-way valve with the function
