Abstract
The utility model discloses a kind of bellow type transfiguration pressure-bearing device.Device comprises bellows, sealing configuration, sealing copper packing, pressure container cylinder, container upper cover, container lower cover and bolt.Bellows one end and pressure container cylinder upper end are weldingly connected, and the other end is obstructed.Pressure container cylinder and container upper cover are connected and fixed by bolt, are lined with sealing copper packing between pressure container cylinder upper limb and container upper cover lower edge.Pressure container cylinder and container lower cover are welded and fixed.Pressurized container upper cover is close is welded with sealing configuration.Be covered with pressurization hole under container, can be connected with supercharging equipment.This device good operating stability, can realize pressure change, save sample under the condition of sample size in not modifier, cost-saving.
Description
Technical field
The utility model belongs to the technical field of pressure resistant vessel, is specifically related to a kind of bellow type transfiguration pressure-bearing device.
Background technique
At present in experiment and Practical Project, usually need to carry out pressure adjustment to equipment and sample.But prior art or direct weighting, or connection buffering pipe pressurizes again, all there are some problems.Sample size needed for prior art is large, and be not suitable for the sample of the higher or rare numbers of some price, application area is restricted.And pressure adjustment needs release often, prior art complicated operation, step is various, also there is certain danger simultaneously.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bellow type transfiguration pressure-bearing device.This device can realize pressure change under the condition of sample size in not modifier, and structure is simple, and clear principle is understandable, easy and simple to handle.
For achieving the above object, the utility model solves the technological scheme that its technical problem adopts and is:
A kind of bellow type transfiguration pressure-bearing device, comprise pressure container cylinder, it is inner that bellows is placed in described pressure container cylinder, and described bellows one end and pressure container cylinder upper end are by being weldingly connected, and the other end is obstructed; Pressure container cylinder and container upper cover are connected and fixed by bolt, are lined with sealing copper packing between pressure container cylinder upper limb and container upper cover lower edge; Pressure container cylinder and container lower cover are by being welded and fixed.
Further, be covered with pressurization hole under described container, be connected with supercharging equipment.
Further, described container upper cover is welded with sealing configuration.
Further, described bellows is flexible welding bellows, and initial texture angle is 30 ~ 35 °.
Whole device needs to be full of sample before use; During use, supercharging equipment need be started pressure adjustment is carried out to pressurized container inside, make bellows produce deformation and then change sample pressure in pipe, realize pressure-bearing; Finish using, only need close supercharging equipment, bellows deformation recovers, and sample Pressure Drop is low to moderate initial value.
Different types of sample can be used, to adapt to the requirement of different experiments inside and outside this device bellows.
The utility model provides a kind of pressure-bearing device reliably, can save sample, cost-saving.
Accompanying drawing explanation
Fig. 1 is bellow type transfiguration pressure-bearing device structural representation of the present utility model.
Accompanying drawing respectively marks implication: 1. sealing configuration, 2. container upper cover, 3. bellows, 4. pressure container cylinder, 5. container lower cover, 6. bolt, 7. seals copper packing.
Embodiment
The embodiment of this model utility is set forth further below in conjunction with accompanying drawing.
As shown in Figure 1, bellows 3 is placed in pressure container cylinder 4 inside.Bellows 3 one end and pressure container cylinder 4 upper end are by being weldingly connected, and the other end is obstructed.Pressure container cylinder 4 and container upper cover 2 are connected and fixed by bolt 6, be lined with and seal copper packing 7 between pressure container cylinder 4 upper limb and container upper cover 2 lower edge.Pressure container cylinder 4 and container lower cover 5 are by being welded and fixed.Container lower cover 5 is provided with pressurization hole, can be connected with supercharging equipment.Container upper cover 2 is welded with sealing configuration 1.
Whole device needs to be full of sample before use, can use different types of sample inside and outside this device bellows.The utility model in use, starts supercharging equipment and carries out pressure adjustment to pressurized container inside sample.Bellows 3 is subject to managing the change of outer sample pressure and produces deformational displacement, volume change, and then changes sample pressure in pipe, realizes pressure-bearing.Finish using, close supercharging equipment, impressed pressure disappears, and namely bellows 3 recovers deformation, and in pipe, sample Pressure Drop is low to moderate initial value.
Above-mentioned example is only for the citing done is described, the restriction not to mode of execution.For those skilled in the art, other multi-form change or variations can also be made on the basis of the above description, these thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
