Description

Internal vacuum valve
Technical field
The present invention relates to a kind of vacuum valve, be specifically related to a kind of for unmanned device and the internal vacuum valve that is connected between vehicle hull with housing of diving under water.
Background technique
At present, all seal casinghousings of underwater hiding-machine, aircraft be connected between housing usually adopt be that wedge ring connects, the machinery type such as clip connected or bolt connection connects, not only manufacturing process is complicated for the component of this several Placement, manufacture difficulty is large, cost is high, and in assembling, detection, Hu Hai examination process, during maintenance conditions dismounting, operator's operation is loaded down with trivial details, labor intensity is large, wastes time and energy, usual dismounting housing dozens of minutes, also may cause colliding with and damaging of product, thus cause the loss being difficult to expect.
Summary of the invention
Technical problem to be solved by this invention overcomes above-mentioned deficiency, a kind of internal vacuum valve is provided, this vacuum valve efficiently solves unmanned device and the connectivity problem between vehicle hull and housing of diving under water, reduce the working strength of operator, shorten assembling. the time of dismounting and detection, improve working efficiency.
Technological scheme of the present invention: a kind of internal vacuum valve, comprise valve pocket 2, valve gap 3, spool 4, orienting pin 5, stop screw 8, first back-up ring 9, first seal ring 10, second back-up ring 11, second seal ring 12, described valve pocket 2 is by packing ring 6, nut 7 is fixed on housing 1, spool 4 is provided with in valve pocket 2, valve gap 3 is located on spool 4, the outer wall of described spool 4 is provided with three annular grooves, the first back-up ring 9 is provided with in each annular groove, first seal ring 10, the outer wall of valve pocket 2 and inwall are respectively equipped with an annular groove, second back-up ring 11, second seal ring 12 is located in the annular groove of valve pocket 2 outer wall, valve pocket 2 is also provided with a through hole 13 be connected with the annular groove on valve pocket 2 inwall, orienting pin 5 is located at position corresponding with valve pocket 2 on housing 1, stop screw 8 is connected with spool 4 through the hole bottom valve pocket 2.
The inner chamber of described spool 4 is " ┷ " font, and under conventional sense, spool 4 and housing 1 inner chamber are airtight vacuum chamber; When spool 4 moves axially 8.5mm along the inwall of valve pocket 2, the inner chamber of spool 4 is communicated with the through hole 13 on valve pocket 2.
The head of a nail diameter of described stop screw 8 is greater than the diameter bottom spool 4.
Described first seal ring 10, second seal ring 12 is O type rubber seal.
The present invention compared with prior art has following beneficial effect: 1. structure of the present invention is simple, uses reliable, and adopt internal vacuum valve to efficiently solve unmanned device and the connectivity problem between vehicle hull and housing of diving under water, the housing of connection is specious.2. the seal ring on spool and the design of the seal ring on valve pocket improve the reliability of product sealing, effectively ensure that between spool and valve pocket, close-fitting sealing reliability between valve pocket and housing.3. the housing of underwater hiding-machine, aircraft and housing adopt original mechanical connection manner, assembling, dismounting need nearly dozens of minutes, and adopt internal vacuum valve to connect, only needed for tens seconds, the time that highly shortened assembling, dismounting like this and detect, reduce the labor intensity of operator, thus improve working efficiency.4. adopt internal vacuum valve to connect housing, make the part of interiors of products keep vacuum state for a long time, improve the degree of staticizing of interiors of products part, thus extend the working life of product.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention vacuumizes state.
Fig. 2 is the structural representation that the present invention vacuumizes done state.
In figure: 1-housing, 2-valve pocket, 3-valve gap, 4-spool, 5-orienting pin, 6-packing ring, 7-nut, 8-stop screw, 9-first back-up ring, 10-first seal ring, 11-second back-up ring, 12-second seal ring, 13-through hole.
Embodiment
A kind of internal vacuum valve, as Fig. 1, shown in Fig. 2, comprise valve pocket 2, valve gap 3, spool 4, orienting pin 5, stop screw 8, first back-up ring 9, first seal ring 10, second back-up ring 11, second seal ring 12, described valve pocket 2 is by packing ring 6, nut 7 is fixed on housing 1, spool 4 is provided with in valve pocket 2, valve gap 3 is located on spool 4, the outer wall of described spool 4 is provided with three annular grooves, the first back-up ring 9 is provided with in each annular groove, first seal ring 10, the outer wall of valve pocket 2 and inwall are respectively equipped with an annular groove, second back-up ring 11, second seal ring 12 is located in the annular groove of valve pocket 2 outer wall, valve pocket 2 is also provided with a through hole 13 be connected with the annular groove on valve pocket 2 inwall, orienting pin 5 is located at position corresponding with valve pocket 2 on housing 1, stop screw 8 is connected with spool 4 through the hole bottom valve pocket 2.
During assembling, first the first back-up ring 9, first seal ring 10 is contained on the annular groove of spool 4, by spool 4 gently push in valve pocket 2, stop screw 8 is filled to bottom spool 4 by the hole bottom valve pocket 2, it is made to be connected with spool 4, to reach spacing effect, finally cover the assembling that namely valve gap 3 completes internal vacuum valve; Valve pocket 2 is put into housing 1 hole prefabricated in advance, load onto orienting pin 5, packing ring 6 is put in bottom, and by tightening nut 7, make internal vacuum valve be fixed on housing 1, that can carry out next step like this vacuumizes work.
