The beneficial effects of the utility model are：
What the 1st, the flange of stainless steel can realize pressure sensor exempts from welded and installed, compared to being welded to connect, flange
Connection temperature tolerance is good, and sealing-off will not occur because of excessive temperature differentials.
2nd, spacing ring can improve support effect of the force pipe to flange, further improve stability.
3rd, interference fit is more preferable compared to the mode stability such as being welded to connect.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is further illustrated.
Fig. 1 is cross section structure diagram of the present utility model；
Fig. 2 is the structural representation of flange.
Specific embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Basic structure of the present utility model is only described in a schematic way, therefore which only shows the composition relevant with the utility model.
As shown in Figure 1 and 2, a kind of steel flange installing type pressure control device, including steel flange 15, protection shell 14,
Upper lid 7, electric switch housing 9, cover plate 12, wire 1, reed 3, switch, movable contact 11, stationary contact 10 and arranged on left and right sides insert
Piece 8, reed 3, movable contact 11 and stationary contact 10 are respectively positioned on 9 inner chamber of electric switch housing, and electric switch housing 9 is located at protection shell
In 14, and the top of electric switch housing 9 and side filling with sealant 2 in shell 14, cover plate 2 is being protected to cover in electric switch shell
At the opening of body 9, one end of reed 3 is connected with the inserted sheet 8 in left side, and the other end is connected with movable contact 11, and stationary contact 10 is located at dynamic
