Description

Thin electric control proportional valve with quick exhaust valve

The present invention belongs to the field of electronically controlled proportional valves, and particularly relates to a thin electronically controlled proportional valve with a quick exhaust valve that can be applied to positive and negative pressures.

Conventional electronically controlled proportional valves usually have only a few external terminals. The terminals are usually used to provide gas for input, output, and exhaust to the atmosphere. If you need to further monitor the details of the aforementioned actions, you must configure additional sensing. Monitor and LED display;

Therefore, in addition to the additional cost of configuring components and the space used for installing components, it is even necessary to readjust the position of the originally set electric control proportional valve, which will also make the installation settings more complicated;

Even though, by adding additional components, the flow path design inside the structure only supports a certain flow rate, so when adjusting the flow rate of external gas input, the incoming flow rate will still be limited by the flow rate of the aforementioned channel, which limits the range of flow adjustment Many; if you need to switch applications on positive pressure and negative pressure at the same time, the related components and configurations are more complicated, and the more space is occupied.

In view of the above-mentioned various situations and problems, the inventor has accumulated many years of development experience in related industries, and after diligently studying and integrating the above-mentioned lack of conventional structures, he has created a thin type with a quick exhaust valve that is more in line with the needs of modern users. Electronically controlled proportional valve;

The new type is a thin electric control proportional valve with a quick exhaust valve. Its main technical purpose is to use a quick exhaust valve in the valve seat, and connect the second flow path and the third flow path of the quick exhaust valve through communication. , The secondary side pressure is monitored by a pressure sensor, so that the secondary side pressure can be generally and massively discharged through one of the aforementioned flow paths according to the flow state, so as to flow to the atmospheric end for discharge, and can cooperate The user needs the pneumatic system to adjust the flow rate of the secondary side pressure.

The second technical purpose of the thin electronically controlled proportional valve with a quick exhaust valve is that the pressure sensor is electrically connected to an LED display. The LED display is provided at a suitable position on the surface of the pressure sensor and can be used To provide information showing the voltage and related pressure status.

The third technical purpose of the thin electric control proportional valve with the fast exhaust valve is to close the fast exhaust valve and apply it to vacuum suction.

Through the above purpose, the new type of monitor is equipped with a fast discharge valve and a pressure sensor for monitoring by adding an LED display, which can switch the flow of the secondary side pressure to different flow paths, so that it can meet the needs of ordinary and large emissions, and can By fixing the state of the quick exhaust valve, it can be applied under positive pressure and negative pressure.
