Background
The float type liquid level meter, the double flange type liquid level meter and the like are very commonly used in the petrochemical industry field and are mainly used for measuring liquid levels of towers, tanks and the like. In the use process of the float type liquid level meter, the double-flange liquid level meter and the like, solid matters such as corrosives, coke powder, oil sludge and the like are often attached to the inner wall of the pressure guide pipe, so that the pressure guide pipe is blocked, or a valve channel of the pressure guide pipe is blocked, the liquid level meter is invalid, and the true liquid level of a tower and a tank cannot be accurately reflected.
Disclosure of Invention
The utility model aims to provide a purging device for a pressure guide pipe of a liquid level meter, which aims to solve the technical problem that the liquid level meter is invalid due to the blockage of the pressure guide pipe and a valve channel of a valve for blocking the pressure guide pipe.
In order to achieve the above purpose, the specific technical scheme of the pressure guide tube purging device of the liquid level meter is as follows:
the utility model provides a level gauge impulse pipe sweeps device, including jar 1, flotation pontoon level gauge 2, sweep pipe 3, impulse pipe valve 4 and tee bend 5 down, jar 1 is connected with flotation pontoon level gauge 2 through upper and lower impulse pipe, is provided with impulse pipe valve 4 down on the impulse pipe down, is provided with tee bend 5 down between impulse pipe valve 4 and the flotation pontoon level gauge 2, and one end of sweeping pipe 3 stretches into down the impulse pipe through a passageway of tee bend, and impulse pipe valve 4 under the direction alignment, sweep the other end termination of pipe 3 and sweep the source.
Further, the purge source is nitrogen.
Wherein the nitrogen pressure is greater than the tank operating pressure.
Further, the purge source is a feed pump or a return pump.
Wherein the feed pump or reflux pump outlet pressure is greater than the tank operating pressure while the medium is the same as the medium in the tank.
The pressure guide pipe purging device of the liquid level meter has the following advantages: the impulse pipe valve is oriented by inserting a purge pipe inside the impulse pipe. The outside of the purging pipe is connected with a nitrogen or feed pump or reflux pump outlet pipeline to be used as a purging source, the purging source is opened periodically, and impurities in the pressure guide pipe are blown back to the tower tank, so that the failure of the liquid level meter is avoided.
Drawings
FIG. 1 is a schematic diagram of a pressure pipe purging device of a liquid level meter.
Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, a pressure tube purging device for a liquid level gauge according to the present utility model will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the liquid level meter impulse pipe purging device comprises a tank 1, a pontoon liquid level meter 2, a purging pipe 3, a lower impulse pipe valve 4 and a tee joint 5, wherein the tank 1 is connected with the pontoon liquid level meter 2 through an upper impulse pipe and a lower impulse pipe, the lower impulse pipe is provided with the lower impulse pipe valve 4, the tee joint 5 is arranged between the lower impulse pipe valve 4 and the pontoon liquid level meter 2, one end of the purging pipe 3 extends into the lower impulse pipe through one channel of the tee joint, the direction is aligned with the lower impulse pipe valve 4, and the other end of the purging pipe 3 is connected with a nitrogen gas or feed pump and a reflux pump pipeline to be used as a purging source. The purge source enters the inside of the impulse pipe through the purge pipe 3, and the lower impulse pipe valve 4 purges and cleans impurities, so that impurities are prevented from adhering to the lower impulse pipe to block the impulse pipe or the valve.
It should be noted that the nitrogen pressure is greater than the tank operating pressure; the feed pump or reflux pump outlet pressure is greater than the tank operating pressure and the medium is the same as the medium in the tank.
In this embodiment, the direction is aligned with the impulse pipe valve by inserting a purge pipe inside the impulse pipe. The outside of the purging pipe is connected with a nitrogen or feed pump or reflux pump outlet pipeline to be used as a purging source, the purging source is opened periodically, and impurities in the pressure guide pipe are blown back to the tower tank, so that the failure of the liquid level meter is avoided.
Although embodiments of the present utility model have been described in conjunction with the accompanying drawings, it will be apparent to those skilled in the art that several variations and modifications may be made without departing from the principles of the utility model, which are also considered to be within the scope of the utility model.
