Fig. 3 is the integrated blade inserting closing pressure controller planar structure schematic diagram of the utility model embodiment.
Specific embodiment
As shown in the figure, a kind of one blade inserting closing pressure controller, including switch housing 13, bottom in switch housing 13
Portion is connected with gas fort 2, and gas fort 2 is connect by connecting pipe 1 with equipment, so as to monitoring device pressure；The middle part of gas fort 2 be provided with every
Plate, 2 top of gas fort are connected with switch inner casing 6 by cover board 5, and cover board 5,4 center of partition board have through-hole, and the setting of 4 bottom surface of partition board is surveyed
Pressuring film plate 3,3 center of pressure measurement diaphragm, which is mounted with, to stretch out cover plate central through-hole upwards under the promotion of 3 tensile force of pressure measurement diaphragm
Porcelain bar 12, in gas fort during pressure change, swelling pop-up porcelain bar or homing fall porcelain bar to pressure measurement diaphragm therewith；Partition board 4 is surveyed
Pressuring film plate 3 is installed in the groove at 2 edge of gas fort, and is passed through the sealing of sealing ring 14 and formed confined space so that equipment pressure control
System is accurate；Be equipped in the installation cavity that is formed with cover board 5 of switch inner casing 6 can contact be connected or detach disconnection movable contact 8,
Stationary contact 7, movable contact 8, stationary contact 7, which are connected separately with, to be stretched out outside switch along the slot on switch inner casing 6, switch housing 13
Pin 9；Stationary contact 7 is fixedly mounted on 5 top of cover board, and movable contact 8 is connect by reed 11 with pin 9, in reed 11
Portion has boss, and porcelain bar 12 can jack up 11 movable contact 8 of reed by boss and leave stationary contact 7, and pressure becomes larger in gas fort
When, swelling pop-up porcelain bar porcelain bar 12 jacks up reed 11 so that movable contact 8 leaves stationary contact 7, blade inserting switch to pressure measurement diaphragm therewith
Pressure controller immediately accordingly controls equipment by pin 9, in gas fort during pressure value back to normal, pressure measurement diaphragm with
Loosen so that porcelain bar 12 resets, reed 11 resets therewith so that movable contact 8 is contacted with stationary contact 7, blade inserting closing pressure control
