FIELD: machine building.SUBSTANCE: invention relates to the insulation devices for differential pressure gauges. Double insulation is specified for two chamber differential pressure gauge, where the differential pressure gauge contains an axial channel (2), in which a plate (3) is installed, it is equipped with hole (4), the plate can be removed to the secondary chamber (6) that is connected with the axial channel (2) via the flow channel (5), at that relatively to the specified flow channel (5) a closure is installed, it is made by two closure elements (8 and 9), that can move independently between position where they do not prevent the above mentioned flow channel (5), and position where they close it.EFFECT: creation of tight closure between the axial channel (2) and secondary chamber (6) to remove plate (3) without termination of the gas or fluid flow via the axial channel (2).2 cl, 7 dwg |
