CONSTANT LOW-PRESSURE SHUT-OFF ELECTROPNEUMATIC VALVE |
摘要 |
FIELD: machine building. ^ SUBSTANCE: constant low-pressure shut-off electropneumatic valve includes high pressure cavity with gas supply channel and low pressure cavity separated from it with fixed seat and shut-off gate and having discharge channel; control electromagnetic valve with inlet seat interconnected with gas supply channel, control element actuated with an electromagnet, and outlet seat interconnected with atmosphere, cylindrical chamber with movable element connected to the stock with shut-off gate and forming the main cavity in the chamber on the stock side, which is interconnected with atmosphere and includes mechanical spring, and on opposite side - auxiliary cavity interconnected with cavity of electromagnetic valve. High pressure cavity is divided into inlet and outlet parts with additional control gate. This gate is a part of shut-off gate and interconnected with inlet part by means of additional movable seat. The latter has the diameter close to the diameter of movable element and is connected to additional element of the specified low pressure adjustment. ^ EFFECT: reduced overall sizes and weight of gas supply system due to enlarged functional capabilities of two-stage shut-off electropneumatic valve. ^ 1 dwg |
