The invention relates to the field of the structure of a barreled beer container.

Background

In the field of barreled beer (big barrel), at present, disposable PET beer barrels are more and more popular in the market, and most of disposable sanitary beer barrels matched with the PET beer barrels are shown in Chinese invention patents with the application number of 202110807444.6, namely a disposable sanitary beer barrel, which is published in 2021, 10, month and 8, and the use process of the disposable sanitary beer barrel can be divided into a cleaning state, a filling ending state and a wine selling state.

However, in the process of storage and transportation, carbonated drinks, especially beer, are likely to release a large amount of carbon dioxide due to the change of temperature or storage and transportation conditions, so that the pressure in the beer barrel becomes high, and once the pressure is too high, the PET barrel may be burst and explode, which causes danger. However, if the pressure release valve is directly arranged on the wine barrel, the existing production line needs to be greatly changed, the construction difficulty is greatly increased, the position of the pressure release valve is difficult to control, and the structural strength of the barrel body is easy to damage.

Therefore, how to improve the wine lance on the existing basis to ensure that the air pressure in the barrel is always within the safe pressure intensity is not too much to increase the construction cost and the construction difficulty, that is, the technical problem to be solved by the technical staff in the field is solved urgently.

Disclosure of Invention

Aiming at the problems, the invention provides a disposable sanitary beer spear with a safety relief valve, which has the advantages of low processing cost, easy assembly and good use effect and can effectively solve the problem that the beer barrel is likely to explode due to overlarge internal pressure.

The technical scheme of the invention is as follows: the safety relief valve is installed on a closed top plate 1031 of the wine lance, a containing hole is formed in the closed top plate 1031, the safety relief valve comprises a valve seat 1 with a large upper part and a small lower part and a return spring 3, the valve seat 1 is contained in the containing hole, the top end of the return spring 3 is fixedly connected with the valve seat 1, the bottom end of the return spring 3 is fixedly installed in a short pipe 103 of the wine lance, and the valve seat 1 is pulled through the return spring 3.

Further, a sealing gasket 2 is sleeved on the valve seat 1.

Further, a pair of U-shaped grooves is formed in the bottom opening of the short pipe 103, a spring hanging shaft 4 is accommodated in the U-shaped grooves, and the bottom end of the return spring 3 is hung on the spring hanging shaft 4.

Furthermore, an annular groove is formed in the spring hanging shaft 4, and the bottom end of the return spring 3 is hung in the annular groove.

Further, the valve seat 1 is T-shaped, the accommodating hole 1032 is a stepped hole adapted to the valve seat 1, the upper portion of the accommodating hole 1032 is in clearance fit with the upper portion of the valve seat 1, a gap is left between the lower portion of the accommodating hole 1032 and the lower portion of the valve seat 1, and the sealing gasket 2 is sleeved on the lower portion of the valve seat 1.

When the invention is used, when the air pressure in the barrel does not exceed a set value, such as 5kg, the reset spring can pull the valve seat due to the self elasticity and enable the sealing gasket on the valve seat to be in a sealing state all the time, thereby keeping the sealing in the PET barrel. When the air pressure in the barrel is too large, the valve seat is pushed by the air pressure to be too large, the reset spring is stressed and stretched, the valve seat is pushed open, the sealing gasket is not guaranteed to be sealed any more, and the gas in the barrel can leave the PET barrel through a gap pulled between the valve seat and the accommodating hole, so that the pressure in the barrel is discharged. After barrel internal pressure diminishes, reset spring's elasticity answer action, the relief valve can be closed again for be in the steady voltage state in the bucket always, thereby can effectively solve the beer barrel and probably because the too big problem that explodes of internal pressure.

More importantly, due to the existence of the sealing gasket, the disposable sanitary wine spear can still keep the sterile and sanitary characteristics after the safety relief valve is added, and has no sanitary dead angle. In addition, the number of parts is small, so that the device also has the advantages of simple assembly, convenient processing and the like.

Detailed Description

In order to clearly explain the technical features of the present patent, the following detailed description is given in conjunction with the accompanying drawings.

The disposable sanitary wine lance comprises a wine lance cover 101 and a short pipe 103 fixedly arranged in the wine lance cover 101, wherein a top opening of the short pipe 103 is provided with a sealing top plate 1031 which is connected with the short pipe into a whole to keep closed, and the bottom of the short pipe 103 is open;

specifically, as shown in fig. 1, the disposable sanitary wine spear comprises a wine spear cap 101, a wine spear sealing seat 102 arranged in the wine spear cap 101, a short tube 103, a spring 104, a spring base 105, and a long tube 106 butted with the short tube 103;

the outer side of the wine lance cover 101 is provided with an annular slot matched with a barrel opening of the PET barrel, and the inner side of the wine lance cover 101 is of a hollow structure;

the spring base 105 is fixedly connected with the bottom of the wine lance cover 101, the short pipe 103 penetrates through the spring base 105, and the spring base 105 and the short pipe are fixedly connected; the wine spear sealing seat 102 is slidably sleeved on the upper part of the short pipe 103, an annular rubber ring is fixedly connected to the top surface of the wine spear sealing seat 102, and the spring 104 is sleeved on the short pipe 103 in an empty mode and is abutted between the sealing seat 102 and the spring base 105; a plurality of air inlets are formed on the spring base 105; the top opening of the short pipe 103 is closed, and the upper part of the side wall of the short pipe is provided with a wine outlet 1030; the top end of the long pipe 106 is in butt joint with the bottom end of the short pipe 103, and the bottom end of the long pipe 106 extends into the bottom of the wine barrel.

When no external force is applied, the rubber ring is pressed between the top of the short pipe and the top opening of the wine lance cover under the action of the spring 104, so that the wine lance cover, the rubber ring and the short pipe are kept sealed.

Like this, when being in the factory state after the filling, the wine lance seal receptacle 102 does not receive external force, and the wine lance lid 101, rubber ring, nozzle stub 103 three keep sealed under the effect of spring, and the inside and outside gas of PET bucket or liquid are all not circulated.

When the user uses the beer bottle, the PET barrel is placed right, the sealing seat 102 of the beer bottle is pressed by external force (such as a distributor) to move relative to the short pipe 103, and then gas, usually CO2, is pressurized and can enter the PET barrel from the air inlet hole along the gap between the rubber ring and the beer bottle cap 101, so that beer in the PET barrel flows out from the beer outlet hole 1030 under the action of pressure.

As shown in fig. 1-5, the safety relief valve is installed on a closed top plate 1031 of the wine spear, a containing hole is opened in the closed top plate 1031, the safety relief valve includes a valve seat 1 with a large top and a small bottom and a return spring 3, the valve seat 1 is contained in the containing hole, the top end of the return spring 3 is fixedly connected with the valve seat 1, the bottom end of the return spring 3 is fixedly installed in a short pipe 103 of the wine spear, and the valve seat 1 is pulled by the return spring 3 to keep the valve seat 1 close to the movement trend of the closed top plate 1031. Therefore, the pressure can be released in the mode of arranging the safety pressure release valve at the top opening of the short pipe when the pressure in the beer barrel is too high, and the problem that the beer barrel is likely to explode due to the too high internal pressure is effectively solved.

In addition, the structure of the scheme is optimized, the processing and assembling sequence of the original wine spear and the PET wine barrel is not needed to be damaged, and only before the short pipe is assembled, all parts of the safety relief valve are processed and assembled in the short pipe, so that the processing cost is low, and the assembly is easy.

The valve seat 1 is also sleeved with a sealing gasket 2. Under normal conditions, the sealing gasket 2 can be compressed between the sealing gasket and the containing hole 1032 by the valve seat 1, so that the pressure relief valve has better sealing effect when being closed.

The valve seat 1 and the annular sealing gasket 2 are of a split structure, no glue is used, and the sanitary effect cannot be influenced.

A pair of U-shaped grooves are formed in the bottom opening of the short pipe 103, a spring hanging shaft 4 is accommodated in each U-shaped groove, and the bottom end of the reset spring 3 is hung on the spring hanging shaft 4. Therefore, the assembly of the spring becomes simpler and more convenient, and after the valve seat is hung and the short pipe is penetrated, the valve seat is pulled out from the bottom opening of the short pipe and is hung on the spring hanging shaft.

An annular groove is further formed in the spring hanging shaft 4, and the bottom end of the reset spring 3 is hung in the annular groove. Therefore, the reset spring 3 can not generate unexpected deflection after being installed, and the stability of the tension of the reset spring 3 is ensured. The problem that the pressure relief effect is influenced due to the fact that the tensile force of the valve plate is changed by the spring after the axis of the spring deflects is avoided.

As shown in fig. 5, the valve seat 1 is T-shaped, the accommodating hole 1032 is a stepped hole adapted to the valve seat 1, the upper portion of the accommodating hole 1032 is in clearance fit with the upper portion of the valve seat 1, a gap is left between the lower portion of the accommodating hole 1032 and the lower portion of the valve seat 1, and the sealing gasket 2 is sleeved on the lower portion of the valve seat 1. Therefore, after being assembled, the sealing gasket 2 forms high-efficiency and good sealing between the valve seat 1 and the step surface of the containing hole, and cannot fall off due to relative movement of the valve seat 1 and the step surface of the containing hole, so that the sealing performance of the position where the sealing gasket 2 is located is further improved, the disposable sanitary beer spear can still keep the sterile and sanitary characteristics after the safety relief valve is added, and no sanitary dead angle exists.

The return spring 4 is a stainless steel spring. Food grade stainless steel may be used.
