Abstract
The utility model discloses a rapid cleaning tee joint, which is characterized in that a straight pipe (1) is a variable diameter pipe with a thick middle section and two thin ends. A filter screen (2) is positioned inside the straight pipe at the connecting position of a perpendicular bent pipe (3) and the straight pipe (1) and placed slantingly towards an inlet end of the straight pipe; inlet ends of the bent pipe (3) and the straight pipe (1) are positioned on the same side of the filter screen; a flange plate A (4) and a flange plate B (5) are respectively arranged at two ends of the straight pipe (1) ; and a flange plate C (6) is arranged at the bottom portion of the bent pipe. The rapid cleaning tee joint has the advantages of fine dust-preventing effect, convenient cleaning and simple structure.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of threeway.
Background technique
In the Coal Production,, fire retardant device all has been installed at gas extraction pipeline (comprising main extraction pipeline and branch line extraction pipeline) for strengthening gas control work.But fire retardant device is because the aperture is little, filter pipe range, bending is many, thereby problems such as existence is easily stopped up, cleaning difficulty.The superfine little coal dust of part enters the gas suction pump cooling water recirculation system through pipeline in addition, acidifying cooling water, corrosion extraction pump has shortened extraction pump working life.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned shortcoming and provide a kind ofly hinder the quick cleaning threeway that dirt is effective, cleaning is convenient, simple in structure.
Quick cleaning threeway of the present utility model, wherein: straight tube is the thin reducer pipes in thick two ends, stage casing.
Above-mentioned quick cleaning threeway, wherein: filter screen be positioned at normal bend and straight tube joint straight tube, tilt to place towards the straight tube entrance point, bend pipe and straight tube entrance point are positioned at the filter screen homonymy.
Above-mentioned quick cleaning threeway, wherein: the straight tube two ends are respectively equipped with flange plate A and flange plate B, and the bend pipe bottom is provided with flange plate C.
The utility model is compared with prior art, has the following advantages, and as can be known from the above technical solutions, there is the change diameter section in threeway, can effectively reduce the mobile speed of mixed gas, deposits most coal dust by action of gravity.The filter screen design is tilted, and has effectively increased the filtration wire side, uses the mesh of 2mm can effectively filter coal dust.During cleaning, only need two valves of regulation and control, just can clear up inner laying dust, clearance time generally about 2mim, can effectively save time, and avoids cleaning to give to draw out methane and brings influence.In the flame trap back this threeway is installed, can effectively prevents the obstruction of flame trap, add the big filter dynamics.Reduce the coal dust quantity that flows to gas suction pump on the whole, effectively prolonged extraction pump working life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Mark among the figure:
1, straight tube, 2, filter screen, 3, bend pipe, 4, flange plate A, 5, flange plate B, 6, flange plate C.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure and feature according to the quick cleaning threeway that the utility model proposes, describe in detail as after.
Referring to accompanying drawing, clear up threeway fast, wherein: straight tube 1 is the thin reducer pipes in thick two ends, stage casing.Filter screen 2 is positioned at normal bend 3 with the straight tube of straight tube 1 joint, towards straight tube entrance point inclination placement, and bend pipe 3 is positioned at the filter screen homonymy with straight tube 1 entrance point.
During use:
Select for use 250 flange plate, flange plate C6 to select for use 377 flange plate, filter screen to select the filter screen of aperture 2mm, straight tube middle part to select for use 377 steel pipes and two ends to select for use 250 steel pipes, bend pipe to select 377 steel pipes for use with flange plate A4 and flange plate B5, the quick cleaning threeway of composition is an example.It is installed in the flame trap back of gas extraction pipeline, after the extraction mixed gas enters 250 steel pipe threeways by flange plate A4, meet straight tube 1 and become diameter expander section (377 steel pipe), the unexpected increasing of diameter, cause the interior gas flow rate of pipe to slow down, in bend pipe (377 steel pipe) lower end, the part micronic dust accumulates on filter screen 2 wire sides coal dusts in the effect deposit of gravity in a large number.Close flange plate B5 place dish valve during cleaning filter screen 2 wire sides, open bend pipe 3 place flange plate C6 place dish valve, clear up inner laying dust, change or clean the filter screen wire side.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
Claims (3)
1. cleaning threeway fast, it is characterized in that: straight tube (1) is the thin reducer pipe in thick two ends, stage casing.
2. quick cleaning threeway as claimed in claim 1 is characterized in that: filter screen (2) is positioned at normal bend (3) with the straight tube of straight tube (1) joint, towards straight tube entrance point inclination placement, and bend pipe (3) is positioned at the filter screen homonymy with straight tube (1) entrance point.
3. quick cleaning threeway as claimed in claim 1 or 2 is characterized in that: straight tube (1) two ends are respectively equipped with flange plate A (4) and flange plate B (5), and the bend pipe bottom is provided with flange plate C (6).
