The utility model discloses a pressure sensor, pressure sensor are provided with the sensor outward and connect, its characterized in that: the tip that the sensor connects is provided with the bellows and connects, is provided with bellow on the bellows connects, and the bellow tip is provided with to pass presses the pipe, the sap cavity is pressed to the biography that is provided with intercommunication pressure sensor and bellow in the bellows connects.
Description
Technical field
This utility model belongs to well pressure measuring equipment technical field, is specifically related to a kind of pressure bomb corrugated tube pressure measurement protection device.
Background technology
Pressure bomb is divided into a variety of according to its function and power supply mode, but the pressure measurement to be completed of topmost function, and the pressure transmission mode of current pressure bomb all uses direct pressure transmission, i.e. by pressure tube, pressure transmission hole, is transmitted on sensor.Many for general water content in crude oil, that viscosity is low measurement media, this pressure measurement pressure transmission mode is no problem；If but running into heavy oil wells and more complicated silt, slurry environment, this pressure transmission mode exists for certain defect, and pressure transmission hole is easy to blocked, causes pressure measurement to be forbidden.Reuse maintenance also inconvenient.
Summary of the invention
This utility model is aiming at the problems referred to above, it is provided that a kind of unaffected at complex environments such as heavy oil wells, silt, mud, does not block and can guarantee that pressure measurement is accurate, can long-term work pressure bomb corrugated tube pressure measurement protection device in the presence of a harsh environment.
In order to realize above-mentioned purpose of the present utility model, this utility model adopts the following technical scheme that, this utility model includes pressure transducer, pressure transducer is outside equipped with sensor connector, it is characterized in that: the end of sensor connector is provided with corrugated pipe connector, being provided with bellows body on corrugated pipe connector, bellows body end is provided with pressure tube, is provided with connection pressure transducer and the pressure transmission sap cavity of bellows body in described corrugated pipe connector.
As a kind of preferred version of the present utility model, described sensor connector is provided with covering corrugated pipe connector and the protection sleeve pipe of bellows body, protection sleeve pipe is provided with through hole.
The beneficial effects of the utility model: this utility model utilizes bellows body as pressure transmission parts, it is to avoid pressure transducer directly contacts with external environment, and the problem preventing the pressure transmission hole of pressure transducer from being blocked occurs；Even if instrument is operated under the adverse circumstances such as heavy oil wells, mud, it is also possible to well protect pressure transducer, it is ensured that pressure transmission and accurately measurement, strong adaptability.The most very convenient in terms of instrument Reusability and maintenance.
It addition, this utility model is by arranging protection sleeve pipe, bellows body can be protected further, it is to avoid bellows body sustains damage and affects pressure transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing 1 be pressure transducer, 2 for anticreep sealing ring, 3 for sensor connector, 4 for O-ring seals, 5 for oil filler point, 6 for pressure transmission sap cavity, 7 for corrugated pipe connector, 8 for bellows body, 9 for back cover, 10 for pressure tube, 11 for through hole, 12 for protection sleeve pipe.
Detailed description of the invention
This utility model includes pressure transducer 1, pressure transducer 1 is outside equipped with sensor connector 3, it is characterized in that: the end of sensor connector 3 is provided with corrugated pipe connector 7, bellows body 8 it is provided with on corrugated pipe connector 7, bellows body 8 end is provided with pressure tube 10, is provided with connection pressure transducer 1 and the pressure transmission sap cavity 6 of bellows body 8 in described corrugated pipe connector 7.
As a kind of preferred version of the present utility model, described sensor connector 3 is provided with covering corrugated pipe connector 7 and the protection sleeve pipe 12 of bellows body 8, protection sleeve pipe 12 is provided with through hole 11.
It is provided with silicone oil in described pressure transmission sap cavity 6.
The oil filler point 5 connected with pressure transmission sap cavity 6 it is provided with on described corrugated pipe connector 7.
It is provided with O-ring seals 4 between described corrugated pipe connector 7 and sensor connector 3.
It is provided with anticreep sealing ring 2 between described protection sleeve pipe 12 and sensor connector 3.
Described pressure tube 10 is connected with bellows body 8 by corrugated tube back cover 9.
During this utility model production and processing, pressure tube 10 and corrugated tube back cover 9 being welded, welding requirements must the most at the uniform velocity rotate, and electric current to be stablized, it is impossible to built-up welding, skip welding, weld crack occurs, and welding personnel disposably to complete.Even weld is smooth.Again by method welding same to corrugated tube back cover 9 and bellows body 8.Finished product technological requirement is the same.Bellows body 8 and corrugated pipe connector 7 are welded by the 3rd step equally, and finished product inspection is qualified.Being assembled with sensor connector 3 by corrugated pipe connector 7, must add O-ring seals 4 during assembling, O-ring seals 4 uses the polyfluoroprene circle of high temperature high rigidity；O-ring seals 4 can ensure instrument long-term work under high temperature, environment under high pressure, is unlikely to owing to long-term vibration comes off.Also function to sealing effectiveness so that silicone oil will not flow out from lower end outlet simultaneously.
After being completed, filling silicone oil, use syringe that by oil filler point 5, the silicone oil of applicable hot environment is injected pressure transmission sap cavity 6, the gas in pressure transmission sap cavity 6 is overflowed by pressure tube 10, then uses swab stick to be blocked by pressure tube 10.Silicone oil must be full of bellows body 8, is finally blocked by jackscrew by oil filler point 5.Remove the swab stick of closure pressure tube 10, install protection sleeve pipe 12 additional, complete this utility model and assemble.
It is understandable that, above with respect to specific descriptions of the present utility model, it is merely to illustrate this utility model and is not limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, still this utility model can be modified or equivalent, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
