Abstract

The utility model discloses a kind of crystallization-preventive liquid level gauge, it is characterized in that: the flange that a. improves and bellows comprise the stainless-steel tube neck of DN100 flange and diameter 100mm, and blowback hole and wire guide are set on DN100 flange, connect DN50 flange in pipe neck one end, DN50 flange connects bellows; B. each pipe neck improved is extended to device interior, measurement bellows is made to go deep into device interior, again by DN100 flange welding on equipment, in the blowback hole on each DN100 flange, anti-blowpipe be set and be connected to pneumatic supply, connecting kapillary in the wire guide on DN100 flange to bellows and transmitter.The utility model has the advantage of: ensure that easy crystallization or easily calm measured medium do not affect the normal use of measurement instrument, thus extend the service time of liquid level gauge.Control to a certain extent and stabilize the safety problem in chemical process, reducing the non-safety factor existed in chemical process.

Description

A kind of crystallization-preventive liquid level gauge

Technical field:

The utility model relates to a kind of liquid level gauge, particularly a kind of crystallization-preventive liquid level gauge.

Background technology:

Existing pair of flange form liquid level gauge mounting means as shown in Figure 1, mainly contains the pipe neck on the equipment of being welded on and flange, bellows, kapillary and transmitter composition.Kapillary two ends are welded on respectively to be measured on bellows and differential pressure transmitter, then is fixed by bolts on the flange of equipment by bellows.When measuring the medium of some easy crystallizations or deposition, because the bellows of existing pair of flange differential pressure levelmeter is connected in main equipment outside by pipe neck and flange, cause the certain media crystallization because temperature reduces herein, form deposition because do not flow, cause alluvial easily make the sediment at pipe neck place more and more and make the blocked dead band of causing of pressure unit bellows so measured medium crystal or sediment are little by little accumulated, affect the normal use of measurement instrument.

Utility model content:

The purpose of this utility model is exactly will solve measured medium crystallization or deposition when existing liquid level gauge is measured easily to cause the problem in dead band, provides a kind of crystallization-preventive liquid level gauge.

The technical solution of the utility model is as follows:

A kind of crystallization-preventive liquid level gauge, is made up of transmitter, kapillary, bellows, flange, transformation accessory, instrument pressure guiding pipe etc., it is characterized in that transformation accessory has done following improvement:

A. the flange improved and bellows, comprise the stainless-steel tube neck of DN100 flange and diameter 100mm, and arrange blowback hole and wire guide on DN100 flange, connects DN50 flange, DN50 flange connects bellows in pipe neck one end;

B, by improve each pipe neck extend to device interior, measurement bellows is made to go deep into device interior, again by DN100 flange welding on equipment, in blowback hole on each DN100 flange, anti-blowpipe be set and be connected to compressor pneumatic supply, connecting kapillary in the wire guide on each DN100 flange to bellows and transmitter.

In the utility model, pipe neck length increases and extends to device interior, measuring diaphragm is made to go deep into device interior, allow the pressure that bellows face and flow media direct contact measurement fluid column height produce, the flowing of medium makes bellows face produce crystallization, extension use flange and original equipment connection.

Blowback hole is set on flange in addition, then instrument air is connected on blowback hole by gauge valve and instrument pressure guiding pipe, utilize blowback air to prevent crystallization to be attached on bellows.

The utility model has the advantage of:

1. the utility model provides a kind of crystallization-preventive liquid level gauge, ensures that easy crystallization or easily calm measured medium do not affect the normal use of measurement instrument, thus extends the service time of liquid level gauge.

2. control to a certain extent and stabilize the safety problem in chemical process, reducing the non-safety factor existed in chemical process.

Accompanying drawing illustrates:

Fig. 1 is existing liquid level gauge schematic diagram;

Fig. 2 is the flange of transformation and the schematic diagram of bellows;

Fig. 3 is the schematic diagram of crystallization-preventive liquid level gauge.

Specific implementation method:

The flange of transformation as shown in Figure 2 and bellows, comprise the stainless-steel tube neck of DN100 flange and diameter 100mm, and arrange blowback hole and wire guide on DN100 flange, utilizes blowback air to prevent crystallization to be attached on bellows.At pipe neck one end blank off perforate welding formation DN50 flange again, DN50 flange connects the bellows of transmitter, object the transmitter bellows being originally arranged on device external is changed into extension be installed to device interior, stops the generation of dielectric deposition thing in bellows face.

Each pipe neck length as shown in Figure 3, extends to device interior, makes measurement bellows go deep into device interior by a kind of crystallization-preventive liquid level gauge that the utility model provides, then by DN100 flange welding on equipment.Arrange anti-blowpipe in blowback hole on each DN100 flange, anti-blowpipe is connected to compressor pneumatic supply.Kapillary is connected to bellows and transmitter in wire guide on each DN100 flange.
