Abstract
The utility model relates to a full-automatic dirt discharge device of a pressure calibration instrument. The device comprises a dirt collector, a dirt discharge seal head, a dirt discharge pipe, a dirt discharge plug, a dirt discharge switch, a switch displacement sensor and a motor, wherein the motor is connected with the dirt discharge switch, and the dirt discharge switch is connected with the switch displacement sensor. The full-automatic dirt discharge device of the pressure calibration instrument is arranged in an oil path or gas path of the instrument, the dirt collector is arranged at the place lower than the whole oil path or gas path, and dirt in a pipeline can be collected in the dirt collector. When dirt discharge is needed, the dirt discharge operation is executed by the instrument, pressure is produced by the instrument, and when the pressure reaches a certain value, the dirt discharge switch is opened to discharge the dirt out of the instrument, so that the purposes of dirt discharge and instrument pipeline washing can be achieved under the condition of not disassembling the instrument.
Description
Technical field
The full-automatic excretion machine of pressure testers can be applied to dirt-collecting, the discharge of hydraulic pressure, atmospheric pressure generation instrument, is mainly used in instrument and meter and industrial automation.
Background technology
Pressure testers is used for the verification Pressure gauge, these are used in various media (gas, liquid) by the Pressure gauge of verification, pressure testers in use for some time, these are by the Pressure gauge of verification, can bring many pollutants, run up to a certain degree after, light then affect the precision and stability of instrument, heavy then stop up internal duct, damage instrument.So present pressure testers will carry out disassembly, cleaning to instrument after using a period of time, clean the filthy loaded down with trivial details work that always is.Each parts wants extreme care to prevent that each sealing surface from damaging in cleaning process behind the instrument removal, after cleaning, instrument also to carry out when mounted the correctness of accurate debugging in order to guarantee to install, the sealing of instrument also will be tested after the installation, prevent the generation of the problems such as poor sealing and little leakage, the full-automatic excretion machine of pressure testers can be realized collection and the blowdown of dirt in the situation of not dismantling instrument, solve a great problem in the instrument cleaning comprehensively.
Summary of the invention
To take the loaded down with trivial details work that instrument cleans internal duct apart in order to overcome existing pressure testers, the utility model provides a kind of pressure testers full-automatic excretion machine, it can be accommodated in dirt in the proprietary container of instrument internal automatically, utilizes in due course the inner pressure that produces of pressure testers that dirt is discharged outside the instrument.
The technical scheme that its technical problem that solves the utility model adopts is:
The full-automatic excretion machine of a kind of pressure testers, it comprises: contaminants collector, blowdown end socket, blow-off pipe, blowdown plug, scum cock, switch bit displacement sensor and motor; Motor is connected with scum cock, and scum cock is connected with the switch bit displacement sensor.After the blowdown instruction arrived, instrument can add certain pressure, and this moment, scum cock was opened, and under the effect of pressure dirt was discharged outside the instrument.
The beneficial effects of the utility model are, can when normal the use dirt in the instrument be collected automatically, and the pressure that utilizes instrument self to produce discharge dirt outside the instrument, do not need to dismantle instrument in whole blowdown process.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the full-automatic excretion machine structure chart of pressure testers of the present utility model
Fig. 2 is the contaminants collector structure chart of the full-automatic excretion machine of pressure testers of the present utility model
Fig. 3 is the blowdown end enclosure structure figure of the full-automatic excretion machine of pressure testers of the present utility model
Fig. 4 is the blowdown stopper structure figure of the full-automatic excretion machine of pressure testers of the present utility model
Fig. 5 is the scum cock structure chart of the full-automatic excretion machine of pressure testers of the present utility model
The represented implication of each Reference numeral is respectively among the figure: 1-motor, 2-sensor, 3-scum cock, 4-blowdown plug, 5-contaminants collector, 6-blowdown end socket, 7-blow-off pipe.
The specific embodiment:
Shown in Fig. 1-5, the full-automatic excretion machine of the described pressure testers of this specific embodiment comprises: contaminants collector (5), blowdown end socket (6), blow-off pipe (7), blowdown plug (4), scum cock (3), switch bit displacement sensor (2) and motor (1): motor (1) is connected with scum cock (3), and scum cock is connected with switch bit displacement sensor (2).Contaminants collector is installed in the oil circuit or gas circuit of instrument, and contaminants-collecting apparatus is lower than whole oil circuit or gas circuit, utilize instrument to produce pressure before the blowdown, after pressure reaches certain value, when blowdown begins, the motor starting scum cock is discharged dirt outside the instrument, can not dismantle the instrument situation and be issued to the purpose of blowdown and comprehensive pipe blow-through thus.The operation principle of the full-automatic excretion machine of pressure testers described in the utility model is as follows:
1: piston moves in piston cylinder and produces pressure and make ducted media flow.
2: the dirt in the medium is when mobile, because Action of Gravity Field enters contaminants collector.
3: the contaminants collector trapped dirt is also waited for blowdown.
4: when needing blowdown, the instrument pressurization produces pressure.
5: motor starting is opened scum cock, under pressure dirt is discharged outside the instrument.
Attention: contaminants collector is lower than whole pipeline, overweight the dirt of medium, under the driving of the round movement of piston, make mobile in pipeline that medium comes and goes, dirt can enter collector owing to action of gravitation in the medium in movement, and can not enter into piston or rest on pipeline.
Claims (1)
1. the full-automatic excretion machine of pressure testers is characterized in that comprising: contaminants collector, blowdown end socket, blow-off pipe, blowdown plug, scum cock, switch bit displacement sensor and motor; Motor is connected with scum cock, and scum cock is connected with the switch bit displacement sensor.
