Description

Thin energy-saving electronically controlled vacuum generating and breaking valve

The new type belongs to the field of electronically controlled vacuum generators, in particular to a thin energy-saving electronically controlled vacuum generation and destruction valve.

For vacuum generators generally used in the industry, the internal structure of the thin electronic control valve is usually designed to allow the gas flow rate to be broken by vacuum. After passing through the vacuum breaker solenoid valve, it is adjusted according to the required flow rate. In practical applications, it is usually necessary After several adjustments, it can be used in a better state.

When the aforementioned vacuum generator is destroyed under vacuum, it usually introduces the destroying gas flow directly under the original vacuum passage inside the suction port. This action often causes the gas flow to flow back to the partially connected passages. This structure This results in a slight instability in the gas flow, and a flat loss of the gas flow.

In view of the various situations and problems of the above-mentioned conventional use, the creator has accumulated years of development experience in related industries, and after painstaking research, after integrating the deficiencies of the above-mentioned conventional structure, he created a thin, energy-saving, electronically controlled vacuum generator that is more in line with the needs of modern users. And destruction valve;

This new model is a thin, energy-saving, electronically controlled vacuum generating and breaking valve. Its main technical purpose is to use a pressure detector to measure the vacuum pressure in the valve seat, and feedback to the control loop through the information, and adjust it through air pressure. The circuit further drives the supply solenoid valve and the break solenoid valve to adjust the vacuum pressure. So far, the creative structure includes: a valve seat with a supply solenoid valve, a break solenoid valve, and a pressure detector, all of which are electrically connected to the control circuit The valve seat has an input port, a discharge port, a suction port, and a vacuum break adjustment button through which the air pressure source can pass. The control circuit is electrically connected to a digital display and is arranged on the outer surface of the valve seat to display the vacuum pressure inside the valve seat A first flow path is respectively connected to the supply solenoid valve and a vacuum generation two-port two-position valve from the input port, and the first flow path is further provided with an air pressure regulating circuit connected to the destruction solenoid valve; The second flow path is connected from the supply solenoid valve to the vacuum generating two-port two-position valve; a third flow path is connected to the vacuum generator by the vacuum generating two-port two-position valve; the fourth flow path is connected to the vacuum generator The generator is connected to the vacuum holding tube to the suction port through the vacuum holding check valve; a fifth flow path is connected to the vacuum breaking tube inside the suction port from the breaking solenoid valve, and the pressure is matched by the vacuum breaking adjusting button The adjustment circuit adjusts the air pressure source to allow the input flow to pre-store the flow required for vacuum breaking, so that the breaking solenoid valve can directly conduct the most appropriate flow to break the vacuum pressure of the sucked workpiece, and then reduce the inverse of the vacuum breaking tube. Flow rate to maintain a stable output of vacuum destruction flow rate.

The second technical purpose is that the vacuum holding check valve is opened and closed to maintain the vacuum state formed from the vacuum holding tube to the suction port for a long time.

The technical purpose again is that the control loop further includes: an MCU microprocessor, which can be used to determine the value of the pressure transmitted by the pressure detector, so as to control the opening and closing of the supply solenoid valve and the destruction solenoid valve. For the purpose of vacuum maintenance or vacuum destruction control.

Through the above-mentioned purpose, the new model uses the flow paths in the valve seat to maintain and break the vacuum, and then use the control circuit, MCU microprocessor, and pressure detector to detect and judge the internal vacuum pressure, and then drive the solenoid valve and break The opening and closing of the solenoid valve makes the vacuum holding control technology more sensitive.

Usually according to this creation, the best feasible embodiment, combined with the detailed description of Figures 1 to 4 of the drawings, will increase the understanding of the new type; the new type is a thin energy-saving electronically controlled vacuum generation and destruction valve, and its structure includes: A valve seat (10) is provided with a supply solenoid valve (20), a destruction solenoid valve (30), and a pressure detector (40), all of which are electrically connected to a control circuit (50). The valve seat (10) It also has an input port (101), a discharge port (102), a suction port (103), and a vacuum breaking adjustment button (11) through which an air pressure source (P) passes. The control loop (50) ) Electrically connected to a digital display (60) arranged on the outer surface of the valve seat (10), which can be used to display the value of the vacuum pressure inside the valve seat (10);

Please refer to the dotted lines in Figure 1, where they are the first flow path (A1). The input port (101) is respectively connected to the supply solenoid valve (20) and a vacuum generating two-port two-position valve ( 12), and the first flow path (A1) is further provided with an air pressure regulating circuit (16) connected to the destruction solenoid valve (30); the second flow path (A2) is connected by the supply solenoid valve (20) Connect to a vacuum generating two-port two-position valve (12); the third flow path (A3) is connected to a vacuum generator (12) from the vacuum generating two-port two-position valve (12); Four flow paths (A4), the vacuum generator (13) connects the vacuum holding tube (15) to the suction port (103) through a vacuum holding check valve (14); a fifth flow path ( A5), the destruction solenoid valve (31) is connected to a vacuum destruction tube (1031) inside the suction port (103), and the vacuum destruction adjustment button (11) is used to cooperate with the air pressure regulating circuit (16) Adjust the air pressure source (P) to allow the input flow to preliminarily accumulate and store the required flow for vacuum destruction, so that the destruction solenoid valve (31) can directly conduct the most appropriate flow to destroy the vacuum pressure of the sucked workpiece, and thereby reduce the vacuum The reverse flow generated by the breaking tube (1031) maintains a stable output of the vacuum breaking flow.

Please refer to Figure 1, which is in a state of preparation for vacuum generation. It can be seen that the air pressure source (P) is input from the input port (101) to the first flow path (A1) and then closed, and the suction port ( 103) The same is closed;

Please refer to Figure 2, under the vacuum generating state, the air pressure source (P) of the first flow path (A1) can be seen to cooperate with the supply solenoid valve (20) to open, and the second flow path (A2) will make the After the vacuum generating two-port two-position valve (12) is opened, and the third flow path (A3) is opened, the air pressure source (P) is discharged to the valve seat (through the vacuum generator (13) through the silencer (1021) 10) Outside, the vacuum holding check valve (14) uses the fourth flow path (A4) to cooperate with the suction port (103) for the purpose of sucking the workpiece.

If there is no need to control the upper and lower limits of the vacuum, it can be directly closed through the menu. When the user controls via an external PLC, he can only issue instructions to turn on and off the MCU microprocessor (51).
