Description
Technical Field
The utility model relates to a level gauge installation technical field, concretely relates to eliminate adjustment structure of glass board level gauge installation stress.
Background
The glass plate liquid level meter can be used for directly indicating the liquid level height in a sealed container, has the advantages of simple structure, intuition, reliability, durability and the like, but the medium in the container must not corrode steel, steel paper and a graphite press ring. The HG5 type glass plate liquid level meter is produced according to the standards of the department of chemical industry HG 5-1364-1370-80 and is suitable for directly indicating the liquid level of media in various containers such as towers, tanks, boxes and the like. The safety steel balls are arranged in the upper valve and the lower valve of the instrument, and when glass is damaged accidentally, the steel balls can automatically close the liquid flow channel under the action of pressure in the container to prevent the liquid level from continuously flowing outwards. The valve end of the meter is provided with a blocking hole screw which can be used for sampling or discharging residual liquid in the meter during maintenance. According to the principle of the communicating vessel, the actual height of the liquid level in the container is directly displayed through transparent glass.
Under the condition that the distance that installation interface on level gauge centre-to-centre spacing and the container was distinguished, the artificial brute force changes the level gauge centre-to-centre spacing, can make the level gauge take place deformation, leads to the inside stress of the glass plate in the level gauge to increase, under medium pressure and temperature variation's influence, leads to the glass plate breakage, awaits urgent need the improvement.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a reasonable in design's elimination glass board level gauge installation stress's adjustment structure, the centre-to-centre spacing of adjustment level gauge that can be convenient, the level gauge does not take place deformation in the installation phase, and the glass plate does not have installation stress.
In order to achieve the above purpose, the utility model adopts the following technical proposal: it comprises an eccentric valve, a connecting pipe, a sealing ring and a fastening nut; the inner end of the inner wall of the eccentric valve is provided with a connecting thread; the fastening nut is in threaded connection with the inner end of the eccentric valve, and a connecting external thread and a smooth surface are integrally formed outside the connecting pipe; the smooth surface is arranged at the outer end of the connecting external thread; the fastening nut is sleeved outside the connecting pipe in a threaded manner, and a sealing ring is embedded between the inner wall of the eccentric valve and the smooth surface; the connecting pipe is connected with the upper end and the lower end of the liquid level meter.
Furthermore, a plug is inserted at the outer end of the eccentric valve.
Furthermore, the eccentric valve is fixedly connected with the outer wall of the container through a flange.
After the structure is adopted, the beneficial effects of the utility model are that: the utility model provides an eliminate adjustment structure of glass board level gauge installation stress, the centre-to-centre spacing of adjustment level gauge that can be convenient, the level gauge is not taking place deformation at the installation phase, and the glass plate does not have installation stress.
