Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluid control technology, and more particularly to an electrically controlled energy-saving slow-start valve. Background Technology
[0002] In semiconductor or electronics assembly plants, a large number of pneumatic components (such as air cylinders, clamps, etc.) are installed to operate with compressed air. However, such manufacturing and processing systems continue to supply air when the machine is on standby or during line changeover, resulting in a waste of energy. This is especially true in multi-station equipment or 24-hour production lines, where pressure loss and air compressor load are even more pronounced.
[0003] While there are methods in the industry such as controlling gas supply through regional independence, monitoring and managing through energy management systems (EMS), or restructuring through pipeline optimization, the actual implementation costs and subsequent maintenance usually require detailed feasibility assessments. Therefore, although these are excellent solutions, they tend to be more suitable for larger-scale plants. Utility Model Content
[0004] The present invention aims to provide an electrically controlled energy-saving slow-start valve to solve the problem of energy waste that may occur during the start-up or standby of fluid systems.
[0005] In existing technologies, fluid systems are often started up with a sudden, full-flow injection, which can easily cause shocks, affecting system stability and potentially leading to energy waste. Furthermore, continuously supplying high-pressure fluid when equipment is in standby or some workstations are not operating also results in unnecessary energy waste.
[0006] To overcome the above-mentioned shortcomings, this utility model provides an electrically controlled energy-saving slow-opening valve, comprising: a main body having an inlet end, an outlet end, and a main channel for fluid passage; a switch module connected to the upper part of the main body, the switch module being electrically connected to a control module, the control module being locked to the side edge of the main body, the switch module internally comprising a slow-opening solenoid valve, a shut-off solenoid valve, a manual valve switch, and a control slide shaft, and a pressure sensor and a flow sensor being disposed between the switch module and the main body; and a valve module connected to the lower part of the main body, and a main valve being disposed between the valve module and the main body.
[0007] When the slow-opening solenoid valve is driven, it also drives the pressure sensor and the flow sensor to monitor, and opens the control slide shaft to a slow-start state with a small flow, so that the primary side pressure flowing in from the intake end flows out from the exhaust end as the primary and secondary side pressures.
[0008] When the pressure sensor and the flow sensor reach a certain sensing value, the shut-off solenoid valve and the main valve are activated to open and close in coordination, so that the primary side pressure flows out through the main valve and the exhaust end, and the secondary side pressure flows out through the exhaust end. The pressure sensor and the flow sensor, which are electrically connected to the control module, are linked by setting the parameter values to complete the linkage between the modules.
[0009] Optionally, the switch module also includes: a manual valve switch, which is embedded in one side of the switch module along with a pneumatic rod. The manual valve switch is electrically connected to the control module and is used in conjunction with the slow-opening solenoid valve and the shut-off solenoid valve.
[0010] Optionally, a flow adjustment screw is provided above the control slide shaft to adjust a return spring of the control slide shaft, thereby cooperating with the slow-opening solenoid valve, the shut-off solenoid valve and the primary side pressure to control the flow rate into the secondary side pressure.
[0011] This utility model discloses an electrically controlled energy-saving slow-start valve. By integrating components such as a slow-start solenoid valve, a shut-off solenoid valve, a pressure sensor, a flow sensor, and a control module, it achieves smooth fluid start-up and intelligent control. When fluid is input into the system, the slow-start solenoid valve first opens to a small flow rate, simultaneously driving the sensor for monitoring. When the secondary side pressure or flow rate reaches a preset value, it then activates the shut-off solenoid valve and the main valve to open to full flow, achieving the purpose of smooth start-up and reducing system impact.
[0012] Furthermore, this invention utilizes sensor feedback to precisely control the opening and closing of the shut-off solenoid valve and the main valve via a control module. This allows for timely shut-off or adjustment of the fluid supply once the system meets operational requirements, avoiding unnecessary energy consumption. Simultaneously, this invention also retains a manual operation mechanism, enabling manual intervention to control the valve opening and closing in special circumstances.
[0013] With the above structure, the electrically controlled energy-saving slow-start valve of this utility model can effectively reduce the impact when the fluid system starts up, and intelligently control the fluid flow according to actual needs, so as to achieve the effects of saving energy, improving system stability and expanding the application range.
[0014] This utility model's electrically controlled energy-saving slow-start valve is applied to pneumatic systems. It can achieve slow fluid startup through electrical control and control valve opening and closing based on sensing parameters to achieve energy-saving effects. Attached Figure Description

[0063] Generally, according to this utility model, the preferred feasible embodiment, in conjunction with the accompanying drawings, Figures 1-9 The detailed description enhances the understanding of this utility model. This utility model discloses an electrically controlled energy-saving slow-opening valve, comprising: an electrically controlled energy-saving slow-opening valve 10, which is mainly composed of a main body 20, a switch module 30, a valve module 40, and a control module 50. The main body 20 has a main channel 23 that allows fluid to pass through, and the two ends of the main channel 23 are an air inlet 21 and an exhaust 22, respectively.
[0064] The switch module 30 is located above the main body 20 and is electrically connected to the control module 50. The control module 50 is locked to the side edge of the main body 20. The switch module 30 internally houses a slow-opening solenoid valve 31, a shut-off solenoid valve 32, a manual valve switch 36, and a control slide shaft 33. The slow-opening solenoid valve 31 and the shut-off solenoid valve 32 have multiple channels connecting to the main channel 23. Therefore, when fluid passes through the slow-opening solenoid valve 31 and the shut-off solenoid valve 32, the channels can be switched ON and OFF in conjunction with electronic control. Above the aforementioned control slide shaft 33, there is also a flow adjustment screw 331. Figure 3 As shown, the spring force of a reset spring 332 is used to adjust the control slide 33 assembly, thereby cooperating with the slow-opening solenoid valve 31, the shut-off solenoid valve 32 and the primary side pressure AA to control the flow rate into the secondary side pressure BB.
[0065] A pressure sensor 34 and a flow sensor 35 are disposed between the switch module 30 and the main body 20. The switch module 30 also includes a manual valve switch 36, which is embedded in one side of the switch module 30 together with a pneumatic rod 37. The manual valve switch 36 is electrically connected to the control module 50 and is used in conjunction with the slow-opening solenoid valve 31 and the shut-off solenoid valve 32.
[0066] Please see as follows Figure 5The valve module 40 is connected to the lower part of the main body 20, and a main valve 41 is provided between the valve module 40 and the main body 20. When the slow-opening solenoid valve 32 is driven, the pressure sensor 34 and the flow sensor 35 are also driven to monitor. The fluid flows out through the A hole in the slow-opening solenoid valve 31 and enters the bottom of the control slide shaft 33 to open the control slide shaft 33 and allow a small flow of secondary side pressure BB, so that the exhaust end 22 enters the slow-opening state. At this time, the slow-opening solenoid valve 32 is ON and the shut-off solenoid valve 32 is OFF. After the slow-opening solenoid valve 31 is driven, the software uses pulse-width modulation (PWM). This method can effectively save the required current, achieve the effect of keeping the slow-opening solenoid valve 31 open, and save power.
[0067] Please see as follows Figure 8 and Figure 9 When the pressure sensor 34 and the flow sensor 35 monitor a sensing value 30A, the shut-off solenoid valve 32 and the main valve 41 are activated to open and close, so that the primary side pressure AA flows out through the main valve 41 and the exhaust end 22, and the secondary side pressure BB flows out. At this time, the slow-opening solenoid valve 31 is OFF and the shut-off solenoid valve 32 is ON. The pressure sensor 34 and the flow sensor 35 are electrically connected through the control module 50. When the secondary side pressure BB reaches a set value 30B of the switching module 30, the shut-off solenoid valve 32 opens the piston 42, and the main valve 41 opens to achieve a slow start state with a large flow. After the shut-off solenoid valve 32 is driven, the software can effectively save the required current through the PWM method, so as to keep the shut-off solenoid valve 32 open and save power.
[0068] Please also refer to the attached diagram. Figures 10-14 When the pressure sensor 34 and the flow sensor 35 reach a sensing value 30A, they can be electrically connected through the control module 50 to further activate the shut-off solenoid valve 32 and the main valve 41 to open and close. This allows the primary side pressure AA to flow out through the main valve 41 and the exhaust end 22, thus controlling the secondary side pressure BB. The control module 50 can adjust parameters to control the energy-saving shut-off position of each module. The first stage of the detailed energy-saving shut-off function is as follows: after the flow sensor 35 senses the value, the slow-opening solenoid valve 31 is OFF and the shut-off solenoid valve 32 is ON. The flow sensor 35 will then detect prolonged low usage to achieve the first stage of energy saving. Please cooperate. Figure 5 Please refer to the following: When the shut-off solenoid valve 32 turns OFF and the slow-opening solenoid valve 31 is OFF, after the shut-off solenoid valve 32 closes, the main valve 41 will also close, and residual pressure will be discharged through the shut-off solenoid valve 32, thereby entering the second stage of energy saving. Please cooperate. Figure 14 See below.
[0069] Please also refer to the attached diagram. Figures 15-19 The manual valve switch 36 in this utility model provides a way to manually release internal pressure. When the manual valve switch 36 is manually operated, the air rod 37 moves upward, and the primary side pressure AA through the main channel 23 pushes the piston 42 downward. At the same time, a no-air-source notification is sent to the control module 50 until the main valve 41 is opened, allowing the primary side pressure AA to be converted from the main channel 23 to the secondary side pressure BB and discharged to the outside.
[0070] Please also refer to the attached diagram. Figures 20-22 The main body 20 is also equipped with a check piston 60. When the input primary pressure AA is less than the predetermined pressure value, the check piston 60 can prevent the formation of secondary pressure BB. However, if the primary pressure AA is greater than the predetermined pressure value, the check piston 60 will be pushed and displaced, which will cause the secondary pressure BB to flow back and be discharged from the air inlet 21 along with the primary pressure AA. The relevant predetermined pressure value can be adjusted and set according to the input of the control module 50.
[0071] This utility model of an electrically controlled energy-saving slow-start valve mainly uses the control module 50 to provide parameter setting values to achieve energy-saving linkage between modules. This includes synchronous monitoring and slow start when fluid is input. When the secondary side pressure BB reaches the set value, the shut-off solenoid valve 32 opens in conjunction with the main valve 41 to achieve a large flow slow start. When the monitored value 30A is reached, the shut-off solenoid valve 32 and the main valve 41 are linked to open and close, so that the control module 50 can control the energy-saving shut-off position by adjusting the parameters. In addition, the manual valve switch 36 can be manually operated to link the air path rod 37 and piston 42 and notify the control module 50 until the main valve 41 opens, so that the primary side pressure AA is converted to the secondary side pressure BB for smooth discharge and application.
