Abstract

The invention discloses accessories for a bubble water machine, and particularly relates to an air exhaust valve for the bubble water machine. The air exhaust valve for the bubble water machine comprises a shell, a sliding rod and a spring, wherein the sliding rod is arranged in an inner cavity of the shell and can slide left and right in the shell, and the shell is provided with an air inlet connector and a pressure relief connector which are communicated with the inner cavity of the shell; the sliding rod is in a split type and is mainly formed by a first rod piece and a second rod piece, the left end of the first rod piece is in contact with a driving rod of the bubble water machine by stretching out of the inner cavity of the shell, the right end of the first rod piece is attached to the left end of the second rod piece, a sealing part of the second rod piece is in interference fit with the inner cavity of the shell, and the first rod piece and the inner cavity of the shell are in direct interference fit or in interference fit through an O-shaped ring. According to the air exhaust valve for the bubble water machine, disclosed by the invention, the performance is reliable, the operation is simple, the air exhaust valve not only can be subjected to manual quick pressure relief, but also has an automatic pressure relief function, and certain beneficial effects are generated.

Description

A kind of air-bubble machine air bleeding valve

Technical field

The invention discloses a kind of air-bubble machine accessory, especially a kind of air-bubble machine air bleeding valve.

Background technology

Tradition air-bubble machine can only carry out manual pressure release with air bleeding valve, does not have the generation that releasing pressure automatically function when air pressure is excessive in air bleeding valve easily causes security incident.

Summary of the invention

The present invention is intended to address the above problem, and a kind of air-bubble machine air bleeding valve is provided, and it has overcome traditional air-bubble machine and has not had the problems such as self-relieving function with air bleeding valve, and its technical scheme adopted is as follows:

A kind of air-bubble machine air bleeding valve, comprise: a housing with inner chamber, sliding bar and a spring that sliding bar can be resetted, described sliding bar is located in the housing inner chamber and can be horizontally slipped in housing, and described housing is provided with intake interface and the pressure release interface communicated with its inner chamber;

Described sliding bar is split typely mainly the first rod member and the second rod member, to consist of, and the inner chamber that the left end of described the first rod member stretches out housing contacts with the drive rod of air-bubble machine, and the left end of right-hand member and the second rod member fits; The inner chamber interference fit of the closure of the second rod member and housing, the direct interference fit of inner chamber of described the first rod member and housing or by O shape circle interference fit;

The gland of air-bubble machine is when down state not, and the first rod member left end is by the drive rod backstop of air-bubble machine, and spring is in compressive state, and the closure of the second rod member is positioned at the pressure release interface and seals the pressure release interface;

The gland of air-bubble machine is when down state, and the closure of the second rod member is positioned at the left side of intake interface, and intake interface and pressure release interface are connected.

On the technique scheme basis, described the first rod member is made by metal material, and described the second rod member is made of plastics.

On the technique scheme basis, described housing mainly is threaded and is formed by the first assembly and the second assembly.

The present invention has following advantage: dependable performance is simple to operate, can manual quick pressure releasing have again the releasing pressure automatically function.

The accompanying drawing explanation

Fig. 1: cross-sectional view of the present invention (when the gland of air-bubble machine is not pressed);

Fig. 2: cross-sectional view of the present invention (when the gland of air-bubble machine is pressed fully);

The specific embodiment

Below in conjunction with accompanying drawing and example, the invention will be further described:

As depicted in figs. 1 and 2, a kind of air-bubble machine air bleeding valve of the present invention, comprise: a 1a of the housing with inner chamber, sliding bar 1b and a spring 1c that sliding bar 1b can be resetted, described sliding bar 1b is located in housing 1a inner chamber and can horizontally slips in housing 1a, and described housing 1a is provided with intake interface 17 and the pressure release interface 15 communicated with its inner chamber;

Described sliding bar 1b split typely mainly is comprised of the first rod member 13 and the second rod member 14, and the inner chamber that the left end of described the first rod member 13 stretches out housing 1a contacts with the drive rod 20 of air-bubble machine, and the left end of right-hand member and the second rod member 14 fits; The inner chamber interference fit of the closure of the second rod member 14 and housing 1a, the direct interference fit of inner chamber of described the first rod member 13 and housing 1a or enclose 16 interference fit by O shape;

The gland 21 of air-bubble machine is when down state not, and the first rod member 13 left ends are by drive rod 20 backstops of air-bubble machine, and spring 1c is in compressive state, and the closure of the second rod member 14 is positioned at pressure release interface 15 places and seals pressure release interface 15;

The gland 21 of air-bubble machine is when down state, and the closure of the second rod member 14 is positioned at the left side of intake interface 17, and intake interface 17 and pressure release interface 15 are connected.

Preferably, described the first rod member 13 is made by metal material, and described the second rod member 14 is made of plastics.

Preferably, described housing 1a mainly is threaded and is formed by the first assembly 11 and the second assembly 12.

Operation principle: the gland 21 of air-bubble machine is when down state not, the closure of the second rod member 14 is positioned at pressure release interface 15 places and seals pressure release interface 15, in air bleeding valve after the excessive deformation values that increases to spring 1c of air pressure, the second rod member 14 moves to right and opens pressure release interface 15, carries out the generation of pressure release Accident prevention; The gland 21 of air-bubble machine is when down state, and intake interface 17 and pressure release interface 15 are connected, but quick pressure releasing.

The above describes the present invention with way of example, but the invention is not restricted to above-mentioned specific embodiment, and all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
