Abstract
The utility model relate to an plug-in type sensor installation device of a gas flowmeter, especially a gas flowmeter on-line installing device. The technical scheme is that the device comprises a lock nut (1), a sensor rod (2), a locking nut (5) and a sensor sheath (6). The sensor rod and the sensor sheath are penetrated into the locking nut. The female thread of the lock nut and the male threadof the locking nut are matched. The diameter of the sensor sheath is larger than the inner diameter of the matchably connected end of the locking nut and the lock nut. The lock nut is unscrewed from the locking nut to make the sensor withdraw from the cavity of the locking nut; at the time, the valve connected with the locking nut is closed; thereby the gas in the pipe will not leak. Because the diameter of the sensor sheath is larger than the inner diameter of the matchably connected end of the locking nut and the lock nut, the sensor is gripped in the locking nut; and the sensor is preventedfrom being extruded out owing to the high pressure in the pipe. The utility model could be installed on site and on-line, thus preventing the sensor from extruding; and is safe and reliable.
Description
Affiliated technical field:
The utility model relates to a kind of online erecting device of plug in sensor erecting device, particularly gas meter of gas meter.
Background technology:
At present, the gas flow timing is installed, because structural limitations, the sensor probe bar can not onlinely be finished installation, needs sometimes to stop production to install, and is very inconvenient, also influences normally carrying out of enterprise's production, brought significant limitation for the use of flowmeter.Someone takes the side to add the mode of pulling-on piece or rope, solves feeler lever retaining problem, and manifold pressure is excessive when preventing to install, and sensor is deviate from, and still, this structural reliability is poor, and security does not guarantee.
The utility model content:
The utility model purpose provides the online erecting device of a kind of gas meter, can on-the-spot online installation, and avoid sensor to deviate from, safe and reliable, solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the online erecting device of gas meter comprises set nut, rodmeter, retaining nut, sensor jacket, rodmeter, sensor jacket are through in the retaining nut, the external thread of the internal thread of set nut and retaining nut is complementary, and the diameter of sensor jacket is connected the internal diameter of an end greater than retaining nut and set nut coupling.
The utility model also is provided with resistance sheath and O-ring seal, is arranged in the retaining nut.
Adopt the utility model, set nut is unscrewed from the retaining nut, sensor can be withdrawed from the chamber of retaining nut, can close the valve that is connected with the retaining nut this moment, and the interior gas of pipeline can not leaked.Because the diameter of sensor jacket mates the internal diameter that is connected an end greater than retaining nut and set nut, and sensor can be stuck in the retaining nut, prevent that manifold pressure senior general sensor from extruding.
The beneficial effects of the utility model are: can on-the-spot online installations, and avoid sensor to deviate from, safe and reliable.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure: set nut 1, rodmeter 2, O-ring seal 3, resistance sheath 4, retaining nut 5, sensor jacket 6.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The online erecting device of gas meter comprises set nut 1, rodmeter 2, retaining nut 5, sensor jacket 6, rodmeter, sensor jacket are through in the retaining nut, the external thread of the internal thread of set nut and retaining nut is complementary, and the diameter of sensor jacket is connected the internal diameter of an end greater than retaining nut and set nut coupling.Also be provided with resistance sheath 4 and O-ring seal 3, be arranged in the retaining nut 5.Set nut 1 unscrews from retaining nut 5, and sensor can be withdrawed from the chamber of retaining nut 5, and can close the valve that is connected with retaining nut 5 this moment, and the interior gas of pipeline can not leaked.Because the diameter of sensor jacket 6 mates the interior warp that is connected an end greater than retaining nut and set nut, and sensor can be stuck in the retaining nut 5, prevent that manifold pressure senior general sensor from extruding.
Claims (2)
1. online erecting device of gas meter, it is characterized in that comprising set nut (1), rodmeter (2), retaining nut (5), sensor jacket (6), rodmeter, sensor jacket are through in the retaining nut, the external thread of the internal thread of set nut and retaining nut is complementary, and the diameter of sensor jacket is connected the internal diameter of an end greater than retaining nut and set nut coupling.
2. according to the online erecting device of the described gas meter of claim 1, it is characterized in that also being provided with resistance sheath (4) and O-ring seal (3), be arranged in the retaining nut (5).
