Description
Technical field
The utility model belongs to drain line technical field, and in particular to a kind of drainage structure for methanol pump.
Background technique
Methanol is mainly used for fine chemistry industry, plastics etc. as a kind of very important Organic Chemicals and high-grade fuel
Field may be utilized in fabricating a variety of organic products such as formaldehyde, acetic acid, chloromethanes, first ammonia, dimethyl sulfate and pesticide and medicine
One of important source material.Methanol can be used as a kind of Novel clean-fuel after deep processing, and gasoline is also added and is used in mixed way.Methanol is
A kind of colourless, transparent, inflammable, volatile toxic liquid.
In the various pumps of conveying methanol, centrifugation pump duty is big, and compact-sized, uniform flow is easy to adjust, using model
It encloses wide.It can be manufactured with high-quality resistant material, being suitable for conveying has corrosive liquid charging stock.Methanol has toxicity and strong corruption
Corrosion, common material can be dissolved by methanol, therefore the sealing ring pumped, impeller, pump cover, the pump housing need to use the good material of corrosion resistance
Material, and need to have good leakproofness, but residual liquid in spiral case cannot be quickly discharged in the existing pump housing.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the utility model is to provide a kind of drains for methanol pump
Structure can be convenient and residual liquid in spiral case is efficiently discharged.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of drainage structure for methanol pump, including steel pipe, steel pipe one end connecting pipe box, other end connected drainage pipe
Road, screw thread engages cap nut, drain line connecting flange on pipe sleeve, and flange connects gland by bolt, nut.
Gasket is placed between the drain line and gland.
The flange is integral with drain line.
The beneficial effects of the utility model are:
The structure may be implemented residual liquid in spiral case and quickly be discharged.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1 is drain line, and 2 be cap nut, and 3 be pipe sleeve, and 4 be steel pipe, and 5 be nut, and 6 be flange, and 7 be gasket,
8 be gland, and 9 be bolt.
Specific embodiment
The utility model is further discussed below below in conjunction with attached drawing.
As shown in Figure 1, a kind of drainage structure for methanol pump, including steel pipe 4,4 one end connecting pipe box 3 of steel pipe are another
Connected drainage pipeline 1 is held, screw thread engages cap nut 2,1 connecting flange 6 of drain line on pipe sleeve 3, and flange 6 passes through bolt 9, spiral shell
Mother 5 connects gland 8.
Gasket 7 is placed between the drain line 1 and gland 8.
The flange 6 is integral with drain line 1.
The working principle of the utility model is:
The pipe fitting of equipment connects tapping pipeline 1, for releasing extra methanol, wherein cap nut 2 and pipe fitting
It is connected, pipe sleeve 3 guarantees the leakproofness of junction, prevents methanol from leaking, and steel pipe 4 is the channel of methanol outflow, flange 6 and gland
Connect with bolt 9 between 8 by nut 5, there is the guarantee leakproofness of gasket 7 in centre, prevent liquid leakage, flange 6 with by steel pipe 4 and
Gland 8, which connects, makes it combine closely to form a kind of dismountable connector, gland is unloaded releasing liquid when tapping, tapping is complete
Cheng Houzai can be used continuously with bolt fastening gland.
