Description

A kind of liquidometer for being easy to clean

Technical field

This utility model is related to a kind of instrument for measuring liquid in container liquid level.

Background technology

In chemical industry production site, liquidometer is used for realizing the monitor in real time to pressure vessel liquid level, while using letter Number teletransmission chain control is realized automatically controlling liquid level.As the safety attachment of pressure vessel, rational operational management and day Often safeguard and be to ensure that its accurately and reliably important means.Liquidometer when in use, needs to form linker with tested container, and then Ensure that tested container is equal with the liquid level of liquidometer measurement pipe.When the float in the transparent measurement pipe of liquidometer changes with tested liquid level When, can be according to the position judgment liquid level of float.There is gas-liquid mixture in the measurement pipe of float level meter.The gas-liquid mixture In often there are various impurity.Because liquidometer measurement pipe cannot be cleaned timely, impurity Jing often blocks magnetic float, leads Cause magnetic float not work, have a strong impact on liquid level and accurately show.And impurity is invested on measurement tube wall, and float is blocked, Operator can be allowed not see the position of float.Therefore, to enable liquidometer normally to work, operator will be periodically to liquid level Measuring buret carries out being vented operation and carrying out maintaining.Because liquidometer measurement pipe does not have emptying device, each maintaining When operator need to loosen measurement pipe flange in the bottom bolt with spanner, loose flange is slow by the gas-liquid mixture in measurement pipe Release.Gas-liquid mixture in measurement pipe can spray under pressure, operator are damaged and working environment is made Into pollution, potential safety hazard is produced, to maintenance work very big difficulty is brought.

Utility model content

In view of this, this utility model provides a kind of liquidometer be easy to and clean, and its inside can be carried out without the need for dismounting Rinse.

To solve above technical problem, the technical solution of the utility model is：A kind of liquidometer for being easy to clean, including it is upper The transparent measurement pipe that lower end is connected by bypass pipe with measured liquid container, being placed with the measurement pipe can float on liquid surface Float；Stop valve is provided with the bypass pipe of the measurement pipe upper and lower side, and measurement pipe upper and lower side is had into water Mouth and outlet；The water inlet and outlet are connected respectively with water inlet pipe and outlet pipe, on the water inlet pipe and outlet pipe It is provided with stop valve.

Used as a kind of improvement, the measurement inner axial tube is provided with stabiliser bar, and the float is placed on stabiliser bar.Stabiliser bar Effect one be to floater guiding so that float along stabiliser bar move up and down.Two is when rinsing inside measurement pipe, it is to avoid float The shock measurement tube wall in the presence of High-Pressure Water, so as to damage measurement pipe.

As a kind of improvement, buffer spring is arranged with positioned at float in the measurement pipe, the buffer spring is placed on On stabiliser bar.Buffer spring is avoided that when not having liquid in measurement pipe that float blocks outlet, causes flushing water flow cycle to be stranded It is difficult.

Used as a kind of improvement, the water inlet pipe connects feed pump.High-Pressure Water is provided for water inlet pipe by feed pump, is strengthened The impulsive force of current, the impurity on tube wall that effectively will can deposit is washed away.

Used as a kind of improvement, the measurement pipe is vertically arranged.

As one kind preferably, the float is spherical.

It is of the present utility model to be beneficial in that：Liquidometer with said structure, increased flusher so that without the need for Liquidometer dismounting just can be cleaned to measurement pipe inside.Substantially increase cleaning efficiency, saved repair and maintenance when Between.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Labelling in figure：1 measurement pipe, 2 floats, 3 stabiliser bars, 4 buffer springs, 5 bypass pipes, 6 water inlet pipes, 7 outlet pipes, 8 sections Only valve.

Specific embodiment

In order that those skilled in the art more fully understands the technical solution of the utility model, with reference to being embodied as The utility model is described in further detail for mode.

As shown in figure 1, the transparent measurement pipe that this utility model upper and lower side is connected by bypass pipe 5 with measured liquid container 1, measurement pipe 1 is vertically arranged.The float 2 that can float on liquid surface is placed with the measurement pipe 1；Float 2 is spherical.The measurement Stop valve 8 is provided with the bypass pipe 5 of the upper and lower side of pipe 1, and the upper and lower side of measurement pipe 1 has water inlet and outlet； The water inlet and outlet are connected respectively with water inlet pipe 6 and outlet pipe 7, are provided with the water inlet pipe 6 and outlet pipe 7 and cut Only valve 8.

Stabiliser bar 3 is axially provided with measurement pipe 1, the float 2 is placed on stabiliser bar 3.The effect one of stabiliser bar 3 be to Float 2 is oriented to so that float 2 moves up and down along stabiliser bar 3.Two are when 1 inside of measurement pipe is rinsed, it is to avoid float 2 is in high pressure The tube wall of shock measurement pipe 1 in the presence of current, so as to damage measurement pipe 1.

Buffer spring 4 is arranged with positioned at float 2 in measurement pipe 1, the buffer spring 4 is placed on 3 on stabiliser bar.Buffering Spring 4 is avoided that when not having liquid in measurement pipe 1 that float 2 blocks outlet, causes flushing water flow cycle difficult.

Water inlet pipe 6 connects feed pump.It is that water inlet pipe 6 provides High-Pressure Water by feed pump, strengthens the impulsive force of current, energy The impurity on tube wall that effectively will deposit is washed away.

When needing to be cleaned liquid level meter, the stop valve 8 being first shut off on upper and lower bypass pipe 5.It is then turned on water inlet pipe 6 With the stop valve 8 on outlet pipe 7, subsequently it is then turned on feed pump and is rinsed for measurement pipe.Rinse after closing, first close water inlet pipe 6 and outlet pipe 7 on stop valve 8, the stop valve 8 being then turned on upper and lower bypass pipe 5.

The above is only preferred implementation of the present utility model, it is noted that above-mentioned preferred implementation should not be regarded It is that, to restriction of the present utility model, protection domain of the present utility model should be defined by claim limited range.For For those skilled in the art, in without departing from spirit and scope of the present utility model, can also make some Improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
