Description of the drawings
Fig. 1 is the general structure schematic diagram of the utility model.
Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings：
It is a kind of to make the mechanical setting of air pressure constant and regulating mechanism in closed container, including closed container cylinder body 1, closed
The top of container cylinder body 1 is provided with air inlet/outlet 2, the elastic sealing gasket 3 with centre bore is provided on air inlet/outlet 2, in band
It is provided with the gland 4 with centre bore on the elastic sealing gasket 3 of centre bore, the top of closed container cylinder body 1 is provided with guide rod box
5, the gland 4 with centre bore is arranged in guide rod box 5, and guide rod is provided on the top end face of guide rod box 5 and stretches out hole 6, guide rod 7 is set
It sets in guide rod box 5, central through hole 12 is provided on guide rod 7, check ring 8 is provided on the bottom outside wall of guide rod 7,
Spring 13 is provided between 5 top plate medial surface of check ring 8 and guide rod box, the upper end of guide rod 7 is stretched out hole 6 by guide rod and is pierced by
To outside guide rod box 5, during the lower end ballhead 9 of guide rod 7 passes through the centre bore movable top on gland 4 to be connected on elastic sealing gasket 3
In the upper port in heart hole, the compressed air inlet pipe being connected to the central through hole 12 on guide rod 7 is provided in the upper end of guide rod 7
14。
It is connected with movable contact ring plate 11 in the upper end of guide rod 7, the top of the guide rod box 5 immediately below movable contact ring plate 11
Fixed contact ring plate 10 is provided on end face, compressed air inlet pipe 14 is connected to air pump 16 one by electric control reversing valve 15
It rises, movable contact ring plate 11 and fixed contact ring plate 10 are electrically connected by electrical control lines and electric control reversing valve 15 respectively；Gas
Pump 16 is constant pressure pump, and air pump 16 passes through the central through hole 12 that is arranged on electric control reversing valve 15, compressed air inlet pipe 14, guide rod 7
The air inlet/outlet 2 and the inner cavity of closed container cylinder body 1 being arranged with the top of closed container cylinder body 1 are connected together, and make closed appearance
Air pressure in the inner cavity of device cylinder body 1 is consistent with the constant pressure that air pump 16 provides, when the air pressure in the inner cavity for closing container cylinder body 1 reduces
When, guide rod 7 can be pressed downward by the preload pressure of spring 13 set, and the centre bore movable top on gland 4 is connected on elasticity
