Fig. 3 is pressure welding bellows string structure schematic diagram.
Wherein, 1 pressure welding bellows string, 2 vacuum welding bellows strings, 3 vacuum end caps, 4 vacuum welding bellowss, 5 centers
Bar, 6 capillaries, cross recess on 7,8 pedestals, 9 Pressure Weldings connect bellows, 10 pressure end caps, 11 lower cross recesses.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings, please refers to Fig.1 to Fig.3.
As shown in Figures 1 to 3, a kind of inline vacuum pressure diaphragm capsule component, including vacuum welding bellows string 2 and pressure welding
Bellows string 1, vacuum welding bellows string 2 and pressure welding bellows string 1 are joined together to form string by electron beam welding welding manner
Connection formula structure, when work is relatively independent to realize that corresponding function, vacuum welding bellows string 2 experience environmental pressure, pressure welding respectively
Bellows string 1 experiences 1 inside and outside pressure difference of pressure welding bellows string.
Vacuum welding bellows string 2 includes vacuum end cap 3, vacuum welding bellows 4, center-pole 5, capillary 6, vacuum end cap
3 are connect with capillary 6 using silver brazing welding manner, vacuum welding bellows 4 respectively with the lower end of vacuum end cap 3 and center-pole
5 are connected by electron beam welding welding manner, all weld joint air-tights, pass through taking out to vacuum welding bellows string 2 for capillary 6
Sky, by evacuating so that center-pole 5 and vacuum end cap 3 constitute chocking construction, when evacuation, needs to guarantee center-pole 5 and vacuum end cap
The certain pressure of the inside cavity of 3 formation, when so that flying height being less than certain altitude, inside and outside differential pressure, which acts on lower capsule stack, to be stopped
Dynamic, when flying height is higher than certain altitude, inside and outside differential pressure acts on lower capsule stack displacement starting, specific inside cavity pressure size
Depending on actual use demand.Then tin-welding seal is carried out to capillary 6, capillary 6 is made to be fully sunk in the center of vacuum end cap 3
Recess effectively reduces the volume of aneroid capsule, ensure that outer mounting structure.
The upper cross recess 7 of ventilation is provided on the contact surface of vacuum end cap 3 and center-pole 5 so that vacuum end cap 3 with
Vacuum welding bellows 4 and center-pole 5 form a cavity.
