Abstract
The utility model relates to a kind of testing apparatus with valve rod bellows component sealing, it includes base, bottom flange, its technological points is: base is upwards fixedly connected sequentially the band ventilation seat of vent and bottom flange, the symmetrical position of bottom flange is threaded respectively and one is parallel to each other and the pull bar perpendicular with bottom flange, the other end of this pull bar is fixedly connected with press table, and this press table has also been threaded a top board; A bellows is also sealedly connected with between bottom flange and press table.Between base and pressing plate, increase bellows, by the stretchability of bellows, adapt to the seal tightness test of different length size band valve rod bellows component, different shaft length size can easily be adapted to.The utility model also has rational in infrastructure, and structure is simple, easy to operate, seal tightness test successful, long service life, the advantages such as application area is wide.
Description
Technical field
The utility model relates to a kind of correlative technology field of bellows component seal tightness test, specifically a kind of testing apparatus with valve rod bellows component sealing.
Background technique
As everyone knows, the general cost of bellows component is higher, is correspondingly used in precision equipment, therefore bellows component relatively, and seal tightness test is indispensable.The seal tightness test of current known band valve rod bellows component, usually different according to different shaft length size design leak tightness test devices.The sealing of energy detection zone valve rod bellows component like this, but cause the cost of the leak tightness test device of band valve rod bellows component to increase, and the leak tightness test device of the valve rod bellows component needing enough space storage to leave unused.
Summary of the invention
The purpose of this utility model is to provide a kind of testing apparatus of band valve rod bellows component sealing of different length dimensional changes of the flexible adaptive zone valve rod bellows component valve rod by bellows.
The technical scheme in the invention for solving the technical problem is: a kind of testing apparatus with valve rod bellows component sealing, it includes base, bottom flange, pull bar, it is characterized in that: base is upwards fixedly connected sequentially the band ventilation seat of vent and bottom flange, the symmetrical position of bottom flange is threaded respectively and one is parallel to each other and the pull bar perpendicular with bottom flange, the other end of this pull bar is fixedly connected with press table, and this press table has also been threaded a top board; A bellows is also sealedly connected with between bottom flange and press table.
The utility model also comprises: bottom flange is connected by adjusting nut with pull bar, for regulating the different length dimensional changes of the flexible adaptive zone valve rod bellows component valve rod of bellows.
The utility model the testing apparatus of bellows component sealing is provided, increase bellows between base and pressing plate, by the stretchability of bellows, adapt to the seal tightness test of different length size band valve rod bellows component, different shaft length size can easily be adapted to, the effective quantity reducing the testing apparatus of the sealing of band valve rod bellows component, the leak tightness test device reducing idle band valve rod bellows component takes up an area space.
The utility model also has rational in infrastructure, and structure is simple, easy to operate, seal tightness test successful, long service life, the advantages such as application area is wide.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the utility model using state structural representation sketch.
1. bases in figure, 2. ventilate seat, 3. pull bar, 4. bottom flange, 5. adjusting nut, 6. bellows, 7. press table, 8. top board, 9. bellows component flange, 10. bellows component valve rod, 11. bellows component bellowss, 12. bellows component end sockets, 13. vents.
The utility model to be described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
Embodiment
As shown in Figure 1, in books 1 are base, 3 is pull bar, base 1 is upwards fixedly connected sequentially the band ventilation seat 2 of vent 13 and bottom flange 4, the symmetrical position of bottom flange 4 is connected with one respectively by adjusting nut 5 be parallel to each other and the pull bar 3 perpendicular with bottom flange 4, the other end of this pull bar 3 is fixedly connected with press table 7, and this press table 7 has also been threaded a top board 8; A bellows 6 is also sealedly connected with between bottom flange and press table.
Operating procedure of the present utility model is as follows: as shown in Figure 2, the testing apparatus top board 8 of bellows component sealing is unloaded, bellows component flange 9 with bellows component bellows is put into press table, length dimension according to bellows component valve rod 10 regulates the length of bellows 6 to meet bellows component valve rod 10 length dimension demand by adjusting nut 5, by screwed tight between top board part 8 and press table 7, again by bellows component flange 9 press seal, bellows component valve rod 10 is fixed by base 1, during to ensure leakage test, balance internal pressure, bellows bellows component is prevented to be destroyed.The utility model stretching by bellows 6 in Fig. 2, and locked by pull bar 3, to meet the different length dimensional changes of bellows component valve rod 10.Thus achieve the purpose of this utility model.
In addition, 12 in Fig. 2 is bellows component end socket.
Claims (2)
1. the testing apparatus with valve rod bellows component sealing, it includes base, bottom flange, pull bar, it is characterized in that: base is upwards fixedly connected sequentially the band ventilation seat of vent and bottom flange, the symmetrical position of bottom flange is threaded respectively and one is parallel to each other and the pull bar perpendicular with bottom flange, the other end of this pull bar is fixedly connected with press table, and this press table has also been threaded a top board; A bellows is also sealedly connected with between bottom flange and press table.
