Problems solved by technology

[0002] Pneumatic valves are widely used in various industries. This type of valve is equipped with a cylinder. The cylinder is divided into an opening cavity and a closing cavity. The switching action of the pneumatic valve is usually controlled by a two-position five-way solenoid valve to control the air entering the opening cavity of the cylinder ( Close the cavity to empty) or close the cavity (open the cavity to empty), but through this control method, the opening / closing action of the pneumatic valve is relatively slow, and the larger the cylinder, the longer the valve action time

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, when the system is running normally, the pneumatic valve realizes the opening or closing operation of the valve through the power-on or power-off of a two-position five-way solenoid valve;

[0018] When it is necessary to quickly operate the pneumatic valve under special circumstances, the two-position five-way solenoid valve 2 and two two-position two-way solenoid valves work at the same time to quickly inflate or deflate the valve cylinder to achieve the purpose of quickly opening or closing the pneumatic valve; When it needs to be opened quickly, the two-position five-way solenoid valve 2 is powered off, and the operating air source enters the cylinder opening chamber 7 through the first vent port 21 and the second vent port 22 of the two-position five-way solenoid valve 2. The source enters the cylinder opening chamber 7 through t...

Abstract

The invention provides a rapid responding pneumatic valve control system. The rapid responding pneumatic valve control system comprises a two-position five-way electromagnetic valve connected with an air cylinder and further comprises a first two-position two-way electromagnetic valve and a second two-position two-way electromagnetic valve. When a pneumatic valve is rapidly closed, an air outlet of the first two-position two-way electromagnetic valve communicates with a closed cavity of the air cylinder, and an air inlet of the second two-position two-way electromagnetic valve communicates with an opening cavity of the air cylinder. When the pneumatic valve is rapidly opened, the air outlet of the first two-position two-way electromagnetic valve communicates with the opening cavity of the air cylinder, and the air inlet of the second two-position two-way electromagnetic valve communicates with the closed cavity of the air cylinder. An operation air source communicates with a first ventilation port of the two-position five-way electromagnetic valve and an air inlet of the first two-position two-way electromagnetic valve. Under special situations, when the pneumatic valve needs to be rapidly operated, the two-position five-way electromagnetic valve and the two two-position five-way electromagnetic valves work at the same time, the air cylinder of the valve is rapidly inflated or deflated, and the purpose of rapidly opening or closing the pneumatic valve is achieved.

Description

technical field [0001] The invention belongs to the technical field of valve control, and in particular relates to a pneumatic valve control system and method capable of quick response under special circumstances. Background technique [0002] Pneumatic valves are widely used in various industries. This type of valve is equipped with a cylinder. The cylinder is divided into an opening cavity and a closing cavity. The switching action of the pneumatic valve is usually controlled by a two-position five-way solenoid valve to control the air entering the opening cavity of the cylinder ( Close the cavity to empty) or close the cavity (open the cavity to empty), but through this control method, the opening / closing action of the pneumatic valve is relatively slow, and the larger the cylinder, the longer the valve action time. [0003] In some special industries, the opening / closing speed of the valve is expected to be slow during normal operation, but in special circumstances (such...
