Description

Emptying pipe

Affiliated field

The utility model relates to a kind of pipeline exhausting device.

Background technique

At present, existing pipeline exhausting device is the electromagnetism emptying on the market, and this emptier is owing to adopt calutron, complex structure, and the cost height, access times are few continuously, and the emptying poor effect, often can not be emptied completely water liquid, and hydropexis takes place.

Summary of the invention

The purpose of this utility model just provides the ducted water of a kind of energy emptying, and simple in structure, the emptying pipe that drainage effect is good.

For achieving the above object, technological scheme provided by the utility model is: a kind of emptying pipe, it comprises body, emptying cap, emptying liner, emptying support, spring, emptying base, the emptying cap is installed on the body, emptying liner, emptying support, spring, emptying base are housed in the smoke releasing cap successively, the emptying liner just in time withstands the exhaust port of emptying crown portion, and the emptying base just in time covers the relief opening of body.

Compared with prior art, because the utility model is taked the mechanical structure emptying, therefore simple in structure, cost is low, and the life-span is long, but the continuous several times use, and emptying is effective.

Description of drawings

Below in conjunction with drawings and Examples the utility model is done and to be described in further detail.

Accompanying drawing is the structural representation of the utility model emptying pipe.

Embodiment

Emptying pipe shown in the accompanying drawing is to be made of body 5, emptying cap 3, emptying liner 1, emptying support 2, spring 6, emptying base 7 etc., and emptying cap 3 is installed on the body 5, and emptying liner 1, emptying support 2, spring 6, emptying base 7 are housed in the smoke releasing cap 3 successively.

When the body 5 of outlet pipe was intake, body 5 internal pressures were big, and the effect emptying liner 1 of spring 6 withstands the exhaust port at emptying cap 3 tops, made outlet pipe keep pipeline unimpeded.When the body 5 of improper outlet pipe discharged water, body 5 internal pressures reduced.External atmosphere pressure is greater than body 5 internal pressures, and spring 6 is compressed, and emptying liner 1 has left the exhaust port at emptying cap 3 tops, and body 5 communicates with the outer atmosphere of outlet pipe, and water can discharge fully in the pipeline thereby can make.

Also be equipped with seal ring 4 between the utility model emptying cap 3 and the body 5, make the sealability of body 5 better.

Claims (2)

1, a kind of emptying pipe, it is characterized in that it comprises body (5), emptying cap (3), emptying liner (1), emptying support (2), spring (6), emptying base (7), emptying cap (3) is installed on the body (5), emptying liner (1), emptying support (2), spring (6), emptying base (7) are housed in the smoke releasing cap (3) successively, emptying liner (1) just in time withstands the exhaust port at emptying cap (3) top, and emptying base (7) just in time covers the relief opening of body (5).

2, emptying pipe according to claim 1 is characterized in that also being equipped with seal ring (4) between described emptying cap (3) and the body (5).
