Description
Technical field
The utility model relates to a kind of compensator, specifically, is a kind of Novel pressure compensator.
Background technology
Pressure transducer is a kind of sensor the most conventional in industrial practice, it is widely used in various industrial automatic control environment, relates to numerous industries such as water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, pipeline.Existing pressure transducer directly contacts with measurement environment when using, and when measurement environment changes, sensor internal is easily mixed into air or impurity, affects its measuring accuracy.
Utility model content
For solving the problem, the utility model provides a kind of Novel pressure compensator, pressure transducer and environment is isolated, and does not affect measuring accuracy simultaneously, is specially adapted to the use of the depthometer of subsea equipment.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel pressure compensator, comprise pressure hull, plug, pneumatic shell cylinder, fexible film, fixed head and be arranged on dry cabin and the pressure transducer of pressure hull inside, described pressure transducer is fixed on pressure hull end cap by ring flange, the probe of pressure transducer is connected with the external world, pneumatic shell cylinder and fexible film two ends are connected by fixed screw and form enclosure space, hydraulic oil is full of in described enclosure space, and with environment UNICOM, described fexible film side is provided with fixed head by fixed screw, described fixed head is furnished with the installation through hole matched with fixed screw, pneumatic shell cylinder upper end offers the screw thread mouth be threaded with plug, plug is furnished with O type ring recess in order to sealing.
As preferably, described fexible film is provided with the through hole for passing for fixed screw.
As preferably, described pneumatic shell cylinder side is provided with the mouth that is threaded for passing for fixed screw.
Compared with prior art, the utility model has the following advantages:
The measuring error always crossed caused by environment change can be avoided, and can pressure transducer be protected, improve its serviceable life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel pressure compensator of the utility model embodiment;
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model embodiment provides a kind of novel pressure compensator, comprise pressure hull 3, plug 6, pneumatic shell cylinder 13, fexible film 9, fixed head 10 and be arranged on dry cabin 2 and the pressure transducer 1 of pressure hull 3 inside, described pressure transducer 1 is fixed on pressure hull end cap 5 by ring flange 4, the probe of pressure transducer 1 is connected with the external world, pneumatic shell cylinder 13 and fexible film 9 two ends are connected by fixed screw 17 and form enclosure space 11, hydraulic oil is full of in described enclosure space 11, and with environment 12 UNICOM, described fexible film 9 side is provided with fixed head 10 by fixed screw 17, described fixed head 10 is furnished with the installation through hole 15 matched with fixed screw 17, pneumatic shell cylinder 13 upper end offers the screw thread mouth 8 be threaded with plug 6, plug 6 is furnished with O type ring recess 7 in order to sealing.
Described fexible film 9 is provided with the through hole 16 for passing for fixed screw 17.
Described pneumatic shell cylinder 13 side is provided with the mouth 14 that is threaded for passing for fixed screw 17.
This concrete installation process of implementing comprises:
1, use syringe to oiling in pressure transducer probe, by air emptying.
2, flexible oil film and fixed head are installed.
3, by screw thread mouth 8 to oiling in container, emptying air.
4, plug is installed, guarantees sealing, installation.
This concrete measuring error implementing can to avoid always crossing caused by environment change, and can pressure transducer be protected, improve its serviceable life.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
