Abstract
The utility model is related to a kind of submersible axial flow pump pit shaft exhaust structures, including three-way pipe, wall pipe, connecting tube, pit shaft lid and seamless steel pipe, being oriented straight up and covering for the first port of three-way pipe sets pit shaft lid, the second port of three-way pipe is oriented horizontally toward side and the horizontally disposed wall pipe of connection, the third port of three-way pipe is oriented straight down and connects the connecting tube being vertically arranged, the seamless steel pipe that the side wall of the first port of three-way pipe and the sidewall weld of second port are obliquely installed.The gas in the first port at the top of three-way pipe can be discharged by the wall pipe that the seamless steel pipe is connected from second port by the way that seamless steel pipe is arranged, realize the effect of pit shaft exhaust gas inside, instead of the effect of manual exhaust valve or automatic exhaust steam valve, so that stable water outlet when submerged axial-flow pump operation, reduces production cost.
Description
Technical field
The utility model is related to pit shaft exhaust technique fields, and in particular to a kind of submersible axial flow pump pit shaft exhaust structure.
Background technology
Existing submersible axial flow pump pit shaft exhaust needs the manually opened air bleeding valve in submerged axial-flow pump startup.Inside pit shaft
The air bleeding valve that pit shaft covers also is turned off manually after gas is drained.When actual motion, scene often forgets to turn on or closes exhaust
Valve.Pit shaft internal gas when water pump operation is caused not empty completely so that outlet pipeline is small when going out big when aqueous condition, and water outlet is not
Stablize.Even it there will be severe loud noise and vibrations.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of submersible axial flow pump pit shaft exhaust structure.
The purpose of this utility model can be realized by following technical proposals：A kind of submersible axial flow pump pit shaft exhaust knot
Structure, including three-way pipe, wall pipe, connecting tube, pit shaft lid and seamless steel pipe, being oriented for the first port of the three-way pipe are vertical
Upwards, first port sets pit shaft lid as the nozzle and lid of pit shaft, and the second port of three-way pipe is oriented horizontally toward side,
Second port connects horizontally disposed wall pipe, and the third port of three-way pipe is oriented straight down, and third port connection is perpendicular
The seamless steel pipe that the connecting tube being directly arranged, the side wall of the first port of three-way pipe and the sidewall weld of second port are obliquely installed,
The both ends of seamless steel pipe are connected to inside first port and second port respectively.
Compared with prior art, the utility model has the advantage of：It can will be at the top of three-way pipe by the way that seamless steel pipe is arranged
Gas in first port is discharged by the wall pipe that the seamless steel pipe is connected from second port, realizes pit shaft exhaust gas inside
Effect, instead of the effect of manual exhaust valve or automatic exhaust steam valve so that stable water outlet when submerged axial-flow pump operation reduces life
Produce cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view at A in Fig. 1.
It is marked in figure as follows：
1 three-way pipe, 101 first ports, 102 second ports, 103 third ports, 2 wall pipes, 3 connecting tubes, 4 pit shaft lids, 5
Seamless steel pipe.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, those skilled in the art is made to become apparent from
How ground understanding puts into practice the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
Referring to Fig. 1 and Fig. 2, a kind of submersible axial flow pump pit shaft exhaust structure, including three-way pipe 1, wall pipe 2, connecting tube 3,
Pit shaft lid 4 and seamless steel pipe 5, the first port 101 of the three-way pipe 1 are oriented straight up, and first port 101 is used as well
The nozzle and lid of cylinder set pit shaft lid 4, and the second port 102 of three-way pipe 1 is oriented horizontally toward side, and second port 102 connects
Horizontally disposed wall pipe 2 is connect, the third port 103 of three-way pipe is oriented straight down, and third port 103 connects to be set vertically
The lower end of the connecting tube 3 set, connecting tube 3 is installed by submersible axial flow pump 6, the side wall and second port of the first port 101 of three-way pipe 1
The seamless steel pipe 5 that 102 sidewall weld is obliquely installed, the both ends of seamless steel pipe 5 respectively with first port 101 and second port
102 inside connections.
The gas in the first port 101 at 1 top of three-way pipe can be passed through the seamless steel pipe 5 by the way that seamless steel pipe 5 is arranged
The wall pipe 2 connected from second port 102 is discharged, and gas flow is referring to shown in arrow in Fig. 2.Also pit shaft exhaust gas inside is just realized
Effect reduce production cost instead of the effect of manual exhaust valve or automatic exhaust steam valve.
It should be pointed out that for the utility model through absolutely proving, can also have a variety of transformation and the implementation of remodeling
Scheme, it is not limited to the specific embodiment of the above embodiment.Above-described embodiment as just the utility model explanation, and
It is not limitations of the present invention.In short, the scope of protection of the utility model should be including those for ordinary skill
It obviously converts or substitutes and retrofit for personnel, and be determined by the appended claims.
