PRESSURE CONTROL VALVE WITH SAFETY DEVICE |
摘要 |
FIELD: machine building.SUBSTANCE: invention relates to has supply systems and industrial pneumatic automation hardware for gas pressure control. Proposed valve comprises the element with moving push-rod for adjustment to preset lower pressure. Besides it has gas feed channel, high-pressure chamber with inlet seat and inlet gate furnished wit extra spring and cylindrical chamber. Moving element with push-rod is articulated with inlet gate to divide the chamber into high-pressure and low-chamber cavities with discharge channel, the latter being separated from high-pressure inlet gate and inlet seat made at rod end and channel in moving element and rod communicated with low-pressure cavity. It is separated from atmosphere by discharge gate connected with inlet gate and discharge seat made at moving push-rod end and communicated with atmosphere via channel in said push-rod. Inlet and discharge gates are made integral and arranged on one side from moving element in high-pressure chamber.EFFECT: higher accuracy of pressure control.1 dwg |
