Description

A kind of carbon dioxide valve for Soda water machine

Technical field

The utility model is related to carbon dioxide valve gate technology fields, especially a kind of carbon dioxide valve for Soda water machine Door.

Background technology

Carbon dioxide gas is pressed into the equipment that soda water is obtained in water, in recent years Soda water machine equipment conduct by Soda water machine Emerging household electrical appliances enter people’s lives, and Soda water machine includes carbon dioxide air source, carbon dioxide valve and injection pipe, dioxy Change carbon valve is one-way pneumatic valve, and carbon dioxide valve includes valve and pneumatic actuator, the secondary cylinder of one-way pneumatic valve It is interior to be equipped with the spring that reset spool.

Authorization Notice No. is CN206513881U in Chinese patent literature, and authorized announcement date is the disclosure on the 22nd of September in 2017 The utility model patent of entitled " a kind of small gas cylinder carbon dioxide valve ", this application discloses a kind of small gas cylinder dioxies Change carbon valve, including valve body, gland, nonreturn valve core, one-way valve seat and spring, institute are equipped with successively from top to bottom in the valve body The valve body stated is connected through a screw thread with gland, and the nonreturn valve core is connected through a screw thread with one-way valve seat, on the gland Equipped with the locating slot for positioning one-way valve seat, one end of the spring is contradicted with valve inner to be connected, the other end and check valve Seat contradicts connection.The utility model of simple structure and strong practicability.Disadvantage is that the sealing of valve is complete by sealing ring At there is no leakproofness self checking structure, can not judge whether valve leaks.

Therefore, because the carbon dioxide of Soda water machine need to be injected into it is for human consumption in water, so the cleaning of carbon dioxide Property need to ensure, if carbon dioxide valve reveal, carbon dioxide pollution can be caused, the soda water generated at this time is just unsuitable for drinking With so a kind of carbon dioxide valve whether energy self-test leaks with external environment of design is just necessary.

Utility model content

The utility model to overcome existing carbon dioxide valve mechanism can not judge valve whether with External leakage not Foot, provides a kind of carbon dioxide valve for Soda water machine, can detect whether valve leaks, and improves Soda water machine manufacture Soda water drinking safety.

To achieve the goals above, the utility model adopts the following technical solution.

A kind of carbon dioxide valve for Soda water machine, including valve body, the interior venthole for being equipped with multi-diameter shaft shape of valve body, valve The side wall of body is equipped with the insurance hole of connection venthole, and safety device is equipped in insurance hole, and venthole is equipped with pressure cap, valve from top to bottom Bar, spool and spring, both ends of the spring contact valve body and spool respectively, and pressure cap is equipped with venthole, slides hole and limit from top to bottom The end face in hole, limit hole can push down spool, and valve rod can be slided sliding in hole, and one end of valve rod reaches valve core inside and withstands valve Core, valve rod is located at the outside of valve core inside and the inside of spool is equipped with the annular groove of cooperation, and it is close to be equipped with No.1 in annular groove Seal, the upside of No.1 sealing ring are contacted with the upper side wall of the limit hole of pressure cap, valve rod be located at the side inside pressure cap be equipped with carry Show ring, the coboundary of prompt ring is parallel with the lower boundary of venthole when spool is closed.

When spool is closed, if venthole and spool are revealed, the gas of leakage is when by prompting ring, since space is from small Become larger, the quick variation of gas flow rate can send out whistle song, so as to prompt connection at spool and valve body whether gas leakage.

Preferably, safety device includes the protecting cap being threadedly coupled with insurance card, protecting cap is close to one end of venthole Equipped with safety plate, safety plate coats the end face of protecting cap, and gasket is equipped between safety plate and valve body, and insurance hole is opposite with gasket End face is equipped with a damping annulus.Safety device safeguards the air pressure balance in valve body, prevents valve inner air pressure from causing valve body in the past Damage, reduces the vibrations of protecting cap by damping annulus, and damping annulus is made to coordinate with protecting cap, improves protecting cap to safety plate Chuck(ing) capacity, improve the safety reliability of safety device.

Preferably, the end face of valve rod towards spool side is bonded with spool.The end face of valve rod is bonded with spool, improves valve Support and ability to bring along of the bar to spool.

Preferably, the outside that pressure cap is located at venthole is equipped with spacing ring, the side that spacing ring is bonded with valve body is equipped with and carries Show annular groove, it is right angled triangle to prompt the cross sectional shape of annular groove.Spacing ring prevents pressure cap over-tightened, prompt annular groove pressure cap with When valve body junction is revealed, gas flows out to the external world after prompting annular groove, due to the variation of gas flow rate, can amplify gas and let out Sound when dew plays suggesting effect when leakage, prevents valve body gas leakage.

Preferably, pressure cap is threaded in the upper end of the venthole of valve body, it is close equipped with No. two between pressure cap and venthole Seal.No. two sealing rings complete the sealing between pressure cap and venthole.

Preferably, the cross sectional shape of the outer end of prompt ring is arc-shaped.Ring is prompted to change gas stream in addition to being kept off as lattice Outside the effect of speed, moreover it is possible to the intensity for reinforcing valve rod improves the working performance of valve rod, prompt the outer end section of ring be it is arc-shaped can also be square Just valve rod slides the sliding in hole in pressure cap.

The utility model is beneficial in that：

1, when spool is closed, if venthole and spool are revealed, the gas of leakage when by prompting ring, gas flow rate it is fast Speed variation can send out whistle song, so as to prompt connection at spool and valve body whether gas leakage, prompt ring that can also reinforce valve rod Intensity, the service life of shadoof carbon dioxide valve；

2, safety device safety performance is reliable；

3, prompt annular groove can amplify sound when gas leakage, play leakage when pressure cap and valve body junction are revealed When suggesting effect, prevent valve body gas leakage.
