Abstract
The utility model discloses a kind of air filter shell drain valves, drain valve is mounted on housing bottom, including with the integrally formed faucet of shell, faucet is in the cylindrical shape extended downwardly, an annular stop piece is equipped in the middle part of faucet inner wall, drain valve further includes a valve plug being used cooperatively with faucet, valve plug includes round patch and stopper rod, round patch is surrounded by flange, it is connected and fixed in the middle part of one end of stopper rod and round patch, the other end extends upwardly to annular stop piece top, and the end of valve rod is equipped with the limited block that an outer diameter is greater than the aperture of annular stop piece；A spring is additionally provided between annular stop piece and round patch, spring is nested in the middle part of stopper rod.Utility model has the advantages that faucet more can hinder the water of external environment to enter air filter using wedge-shaped cylindric and flange be used cooperatively；When air filter is negative pressure, round patch is up moved, better tightness；Return spring is set in faucet, avoids round patch stuck in faucet.
Description
Technical field
The utility model relates to a kind of drain valve, especially a kind of air filter shell drain valve.
Background technique
Currently, air filter shell is internal in extreme environment to condense into water, the time is long, and water can not be discharged, can direct shadow
The normal use of air filter shell is rung, therefore, the air filter shell that must just develop one kind can drain is not found through retrieving
Technical solution identical with the technical program.
Utility model content
The purpose of this utility model provides a kind of structure air filter shell drain valve simply easy to use, solves above-mentioned existing
One or more in technical problem.
In order to solve the above technical problems, the technical solution of the present invention is as follows: a kind of air filter shell drain valve, drain valve are mounted on
Housing bottom, innovative point are: including with the integrally formed faucet of shell, faucet is in the cylindrical shape that extends downwardly, out
An annular stop piece is equipped in the middle part of water nozzle inner wall, drain valve further includes a valve plug being used cooperatively with faucet, and valve plug includes circle
Shape patch and stopper rod, round patch are surrounded by flange, are connected and fixed in the middle part of one end of stopper rod and round patch, the other end
Annular stop piece top is extended upwardly to, the end of stopper rod is equipped with the limited block that an outer diameter is greater than the aperture of annular stop piece；Ring
A spring is additionally provided between shape limit film and round patch, spring is nested in the middle part of stopper rod.
In some embodiments, the bottom interior wall of faucet is in the wedge shape that aperture is gradually increased from top to bottom, the circle
The flange of shape patch surrounding can be meshed with the wedge structure of faucet inner wall.
Utility model has the advantages that the good airproof performance of the technical program, faucet uses wedge shape cylindrical shape and flange
With the use of more the water of external environment capable of being hindered to enter air filter；When air filter is negative pressure, round patch is up moved, and makes circle
The magnitude of interference of patch and faucet is bigger, better tightness；Return spring is set in faucet, avoids round patch stuck and is going out
In water nozzle.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of air filter shell drain valve of the utility model.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in more detail.
A kind of air filter shell drain valve as shown in Figure 1, drain valve are mounted on 1 bottom of shell, including with 1 one of shell at
The faucet 2 of type, faucet 2 are in the cylindrical shape extended downwardly, are equipped with an annular stop piece 5, drain valve in the middle part of 2 inner wall of faucet
It further include a valve plug being used cooperatively with faucet 2, valve plug includes that round patch 3 and stopper rod 4, the surrounding of round patch 3 are set
There is flange 7, is connected and fixed in the middle part of one end of stopper rod 4 and round patch 3, the other end extends upwardly to 5 top of annular stop piece, plug
The end of bar is equipped with the limited block 6 that an outer diameter is greater than the aperture of annular stop piece 5；Between annular stop piece 5 and round patch 3 also
Equipped with a spring, spring is nested in 4 middle part of stopper rod.
In some embodiments, the bottom interior wall of faucet 2 is in the wedge shape that aperture is gradually increased from top to bottom, the circle
The flange 7 of shape patch surrounding can be meshed with the wedge structure of 2 inner wall of faucet.
Utility model has the advantages that the good airproof performance of the technical program, faucet 2 uses wedge shape cylindrical shape and flange
7 be used cooperatively more can hinder the water of external environment to enter air filter；When air filter is negative pressure, round patch 3 is up moved, and makes to justify
Shape patch 3 and the magnitude of interference of faucet 2 are bigger, and return spring is arranged in 3. faucet 2 of better tightness, avoids round patch 3
It is stuck in faucet 2.
The scope of the present invention is defined by the appended claims and its equivalents.The above is only that this is practical
Novel preferred embodiment, it is noted that those skilled in the art, do not departing from the concept of the present invention
Under the premise of, some similar deformation and improvement can be made, these also should be regarded as within the protection scope of the utility model.
