The back washing anti-blocking magnetic liquid level meter is composed of a blind plate flange, an upper flange, a floater chamber, a magnetic floater, an upper connection flange, an upper connection pipe, a magnetic display plate, a hoop, a lower connection flange, a lower connection pipe and a lower flange. The upper flange is welded to the upper end of the floater chamber, the blind plate flange covers the upper flange welded with one end of the upper connection pipe, the other end of the upper connection pipe is welded above the floater chamber, the magnetic display plate is fixed outside the floater chamber, the magnetic floater is installed in the floater chamber, and the lower connection flange is welded with one end of the lower connection pipe. The back washing anti-blocking magnetic liquid level meter is characterized in that a filter is installed between the lower connection pipe and the floater chamber, the lower end of the filter casing is welded with the lower flange, and a pollution discharge pipe assembly and a pollution discharge valve are installed at the lower end of the lower flange. Compared with the existing magnetic liquid level meter, the back washing anti-blocking magnetic liquid level meter enables liquid entering the floater chamber to be filtered without impurities attached on the inner wall of the floater chamber and enables the floater to flexibly float vertically to correctly display the liquid level.
Description
Affiliated technical field
The utility model relates to the magnetic fluid level gauge that uses on a kind of Chemical Manufacture and the fluid reservoir.
Background technology
Employed magnetic fluid level gauge does not all have filtration unit on Chemical Manufacture and fluid reservoir at present; This weak point that does not have a magnetic fluid level gauge of filtration unit is that the impurity in the liquid is prone on the tube wall attached to the float chamber of magnetic fluid level gauge; Make ball float be attached that impurity on float chamber's tube wall is blocked and can not float very flexibly up and down, thereby can not correctly show the height of liquid level.
The utility model content
The purpose of the utility model is to overcome the weak point of used magnetic fluid level gauge on Chemical Manufacture and fluid reservoir at present, and a kind of anti-blocking magnetic fluid level gauge of back flush that filtration unit is housed is provided.
The purpose of the utility model realizes through following technical scheme.The anti-blocking magnetic fluid level gauge of back flush by blind flange, upper flange, float chamber, magnetic ball float, go up joint flange, go up connecting pipe, magnetic display board, anchor ear, down joint flange, connecting pipe and lower flange are formed down.Upper flange is welded in the upper end of float chamber; Blind flange covers on upper flange, the end welding of last joint flange and last connecting pipe, and the other end of last connecting pipe is welded in the top of float chamber; Magnetic display board is fixed between the last connecting pipe and following connecting pipe outside the float chamber with anchor ear; The magnetic ball float is contained in the float chamber, and the end welding of following joint flange and following connecting pipe is being equipped with filtrator between connecting pipe and float chamber down; The lower end of filter housing and lower flange welding, blow-off pipe assembly and blowoff valve are equipped with in the lower end of lower flange.
Filtrator is made up of shell and filter screen, and filter screen is welded in the lower end of float chamber, the welding of top slightly of the upper end of filter housing and float chamber and filter screen weld, and the other end of following connecting pipe is welded in the top of filter housing.
The blow-off pipe assembly is by the blowdown flange, and blow-off pipe and short circuit flange are formed, an end of blow-off pipe and the welding of blowdown flange, the other end and the welding of short circuit flange.
After processing by technique scheme, link to each other with the last joint flange of at present used magnetic fluid level gauge last joint flange and following joint flange with the corresponding pipeline of following joint flange, can come into operation.
The utility model with at present on Chemical Manufacture and fluid reservoir the used magnetic fluid level gauge that does not have filtration unit compare; Have because of between connecting pipe and float chamber filtrator being housed down; Make the liquid that gets into the float chamber through filtration and inclusion-free; Occur thereby do not have the impurity that adheres on the inwall of float chamber, ball float can be floated up and down in the float chamber flexibly, advantage that can be correct from magnetic display panel demonstration liquid level height.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model, and Fig. 2 is the present structural representation of the used magnetic fluid level gauge that does not have filtration unit on Chemical Manufacture and fluid reservoir.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.In the accompanying drawing: the 1-blind flange; The 2-upper flange; The 3-float chamber; The 4-magnetic display board; The 5-filter screen; The 6-filter housing; 7-magnetic ball float; 8-lower seal pad; The 9-lower flange; 10-blowdown flange; The 11-blow-off pipe; 12-short circuit flange; The 13-blowoff valve; Joint flange under the 14-; Connecting pipe under the 15-; The 16-anchor ear; The last connecting pipe of 17-; The last joint flange of 18-; The last gasket seal of 19-.During enforcement, blind flange 1, upper flange 2, float chamber 3; Magnetic display board 4, magnetic ball float 7, following joint flange 14; Following connecting pipe 15, anchor ear 16, last connecting pipe 17; Last joint flange 18 and last gasket seal 19, above-mentioned these parts can not change with the part on magnetic fluid level gauge used on Chemical Manufacture and the fluid reservoir is identical at present.The innovative point of the utility model only is increasing filtrator between connecting pipe 15 and the float chamber 3 down.Lower flange 9 will strengthen than present lower flange on magnetic fluid level gauge used on Chemical Manufacture and the fluid reservoir; Should be complementary with filter housing 6; The gap that 15mm～20mm should be arranged between the internal diameter of filter housing 6 and the filter screen 5, promptly the internal diameter of filter housing 6 should be than the external diameter of filter screen 5 big 30mm～40mm.The operating position of the utility model is described below.During use, with liquid in the container that the utility model links to each other through joint flange 14 down, following connecting pipe 15 gets into filtrators, filter the back through filter screen 5 and get in the float chamber 3, when the liquid in the container goes up and down, the also up-down thereupon of magnetic ball floats 7 that float chamber 3 is interior.The magnet steel of the permanent magnetism in the magnetic ball float 7 passes through the magnetic couple transmission to magnetic display board 4; Drive red or turn over 180 ° of post upsets in vain; When liquid level rises (being that magnetic ball float 7 rises), turn over post and transfer redness to by white, during decline then redness transfer white to; Place, position, red white boundary on the magnetic display board is the true altitude of container inner medium liquid level, and it is coupled through magnetic and shows that liquid level principle just is identical with method with present used magnetic fluid level gauge.After using a period of time, the impurity of filtrator Inner filter net 5 outsides can get more and more, and has hindered flowing of liquid; The valve (not drawing in the accompanying drawing) that at this moment will play joint flange 14 front ends to link to each other is closed; Open blowoff valve 13, at this moment the liquid in the float chamber 3 from blowoff valve 13 blowdowns, is discharged with liquid the impurity of filter screen 5 outsides with the method for recoil under action of gravity from blowoff valve 13; After recoil is clean; Blowoff valve 13 cuts out, open the valve (not drawing in the accompanying drawing) of following joint flange 14 front ends, the utility model can continue to use.
