Abstract
The utility model discloses a guided wave radar level transmitter which relates to a structure improvement of the guided wave radar level transmitter. The utility model provides a guided wave radar level transmitter with good sealing, which comprises a header and a probe. A measuring rod arranged in the shell of the probe is a sheath whose top is connected with an insert part arranged in an insulator. A seal gasket is arranged between the slant in the shell of the probe of the structure element and the measuring rod. A groove and a convex central are arranged on the measuring rod and the rigid case which are connected with the seal gasket. The top of the seal gasket is provided with a rigid case and a nut.
Description
Technical field:
The utility model relates to the improvement of guided wave radar fluid level transmitter structure.
Background technology:
The guided wave radar fluid level transmitter is made up of gauge outfit and probe.Because its measuring accuracy height, maintenance is few, adaptation is wide, obtain using very widely in industries such as petrochemical compleies.But also there is following shortcoming:, often leak (for example: factory of shanghai refinery is using the guided wave radar fluid level transmitter just to leak less than two months) because the hermetically-sealed construction of probe is unreasonable, using and keep in repair and brought very big inconvenience to the user.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of guided wave radar fluid level transmitter of good airproof performance is provided.
The utility model adopts following technical scheme, the utility model comprises gauge outfit, probe, sounding rod in the housing of probe is outward a sheath, the top of sounding rod links to each other with the plug connector in the insulator, be provided with sealing gasket between inclined-plane in its structural feature probing shell and the sounding rod, be respectively arranged with groove, bulge loop on the sounding rod that contacts with sealing gasket, rigid enclosure, the top of sealing gasket is rigid enclosure, nut.
The beneficial effects of the utility model:
Because be provided with sealing gasket between inclined-plane in the probing shell of the present utility model and the sounding rod, the top of sealing gasket is rigid enclosure, nut, just can compress seal by nut, rigid enclosure, and seal is contacted closely with inwall, the sounding rod of housing; Sounding rod and sealing gasket are interference fit, and have groove more to help sealing on the sounding rod, and rigid enclosure is provided with a bulge loop can make encapsulant fully be out of shape, and makes sealing more reliable.
Product of the present utility model compares with existing guided wave radar fluid level transmitter performance:
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram of probe;
Fig. 3 is the local enlarged diagram of Fig. 2.
Embodiment:
The utility model comprises gauge outfit 1, probe 2, outside the sounding rod 4 in the housing 5 of probe 2 is sheath 3, the top of sounding rod 4 links to each other with the plug connector in the insulator 16 15, pop one's head in and be provided with sealing gasket 11 between inclined-plane 7 in 2 housings 5 and the sounding rod 4, be respectively arranged with groove 9, bulge loop 8 on the sounding rod 4 that contacts with sealing gasket 11, rigid enclosure 10, the top of sealing gasket 11 is rigid enclosure 10, nut 12.
Sealing gasket 11 materials of the present utility model can adopt teflon.
Above sealing gasket 11, be provided with U-loop 14, can play the effect of fine counnter attack ejected wave, guarantee to measure quality.
Sealing gasket 11 can be fixed on the sounding rod 4 by jump ring 6, pad 13.
