The utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of mechanical seal mounting structure.
Described a kind of mechanical seal mounting structure, comprise upper mounting plate, lower installation board and sensor, upper mounting plate and lower installation board are by the screw threaded, be provided with through hole in the lower installation board, it is characterized in that being provided with on the described upper mounting plate mounting groove on several sensors, be provided with mounting groove under the sensor corresponding with mounting groove on the sensor on the lower installation board, the bottom of mounting groove is provided with the aperture that communicates with through hole in the lower installation board under the sensor, on described sensor and the described sensor under mounting groove, the sensor mounting groove be connected.
Described a kind of mechanical seal mounting structure, it is characterized in that mounting groove is set to the wide-mouth shape on the described sensor, the circumference of mounting groove is provided with groove under the sensor, and the O RunddichtringO is set in the groove, seals by the O RunddichtringO between the mounting groove under mounting groove and the sensor on the sensor.
Described a kind of mechanical seal mounting structure, it is characterized in that described sensor lower end is provided with the first seal groove, jump-ring slot and the second seal groove, the one O RunddichtringO is set in the first seal groove, C type snap ring is set in the jump-ring slot, the 2nd O RunddichtringO is set in the second seal groove, mounting groove on a described O RunddichtringO seal sensor and the sensor, mounting groove under the 2nd O RunddichtringO seal sensor and the sensor, the outstanding outer rim of C type snap ring is positioned at mounting groove under the sensor.
Of the present utility model simple in structure, be skillfully constructed, the cooperation by O-ring seal and C type snap ring has realized the Fast Installation of sensor and good sealing property, also not Existential Space restriction during dismounting, cost is low, and is convenient for installation and maintenance.

Embodiment
Below in conjunction with Figure of description the utility model is described further:
A kind of mechanical seal mounting structure, comprise upper mounting plate 2, lower installation board 7 and sensor 1, upper mounting plate 2 and lower installation board 7 are by screw 6 threaded, be provided with through hole in the lower installation board 7, be provided with mounting groove on several sensors at upper mounting plate 2, be provided with mounting groove under the sensor corresponding with mounting groove on the sensor on the lower installation board 7, the bottom of mounting groove is provided with the aperture that communicates with through hole 9 in the lower installation board under the sensor, on sensor 1 and the sensor under mounting groove, the sensor mounting groove be connected, namely structure is complementary.
In order to guarantee the easy for installation of sensor, mounting groove is set to the wide-mouth shape on the sensor, make things convenient for like this installation of C type snap ring 4, the circumference of mounting groove is provided with groove under the sensor, O RunddichtringO 8 is set in the groove, realizes sealing by O RunddichtringO 8 between the mounting groove under mounting groove and the sensor on the sensor.
The sensor lower end is provided with the first seal groove 3a, jump-ring slot 4a and the second seal groove 5a, the one O RunddichtringO 3 is set in the first seal groove 3a, C type snap ring 4 is set in the jump-ring slot 4a, the 2nd O RunddichtringO 5 is set in the second seal groove 5a, mounting groove on the one O type sealing 3 circle seal sensors and the sensor, mounting groove under the 2nd O RunddichtringO 5 seal sensors and the sensor, C type snap ring 4 outstanding outer rims are positioned at mounting groove under the sensor.
In the time of need to safeguarding dismounting, back out screw, the lower installation board of dismantling makes C type snap ring produce distortion with anchor clamps, and is so that C type snap ring external diameter can be pulled out sensor less than mounting groove internal diameter on the sensor, simple and convenient.
Principle of work: the liquid that is positioned at the lower installation board through hole communicates with sensor by aperture, and the sensor contact liq is the exportable temperature that collects or pressure data.
Sealing principle: liquid at first will contact the 20 RunddichtringO, if this road protection was lost efficacy, liquid enters C type snap ring place, this moment, the O RunddichtringO formed protection again with the setting of an O RunddichtringO, therefore, the probability of leakage reduces greatly, is greatly improved sealing life simultaneously.
Structure of the present utility model is applicable to the situation that a plurality of sensors are set up in parallel, when user's actual needs more during multisensor, as long as in like manner increase just passable, very convenient.
