Detailed Description

The present invention is further described below with reference to the accompanying drawings and examples:

example 1:

A split electromagnetic valve is shown in fig. 1, and comprises a valve body structure 100, wherein the valve body structure 100 is connected with a feeding pipe 13 to fix a gas path connecting end 9, and a gas injection back pressure unit penetrates through the valve body structure 100 through a back pressure pipe 7.

In the application of the production line, the electromagnetic valve can be fixed on the automatic production line through the external connection end.

As shown in fig. 1 and 2, the valve body structure 100 includes an upper valve seat 5 and a lower valve seat 6, which are fixed in a sealing manner, and in this embodiment, a bolt sealing manner is adopted in the connection manner.

That is, the upper valve seat 5 and the lower valve seat 6 are connected by bolts, and a seal ring is provided at the connection portion to seal.

A piston cavity 101 and a filling cavity 102 are respectively arranged up and down in the valve body structure 100; the piston chamber 101 is used for placing the piston 51 therein. A filling opening 103 is formed in the lower side of the filling cavity 102, a sealing plug 11 is connected with the piston 51 in the piston cavity 101, and the filling opening 103 is sealed at the lower side;

In a specific structure, the lower side of the sealing plug 11 is a plug end 111, the upper side is a connecting pipe 112 connected with the piston 51, and the connecting pipe 112 and the valve body structure 100 are sealed and divide the filling cavity 102 and the piston cavity 101 into two independent sections.

That is, a sealing ring is provided between the connection pipe 112 and the inner passage of the lower valve seat 6.

It should be noted that the pressing groove of the upper sealing ring of the connecting pipe 112 is provided with a vertically sliding section when pressing the sealing ring under the action of the inner wall of the lower valve seat 6, that is, the sealing plug 11 is continuously in sealing with the lower valve seat 6 in the vertical movement process, so that the filling cavity 102 and the piston cavity 101 can be effectively formed into independent cavities.

Namely, the two mediums are separated, the cleaning dead angle is removed, and the filling effect is improved.

The piston 51 divides the piston chamber 101 into upper and lower chambers, and the first solenoid valve 10 opens the lower chamber.

In this solution, the sealing ring structure disposed between the piston 51 and the inner wall of the upper valve seat 5 can isolate the upper chamber from the lower chamber.

Specifically, in the lower cavity, the first electromagnetic valve 10 is connected to the air path, and introduces a source power for driving the piston 51, and when the piston 51 moves, the sealing plug 11 is driven to reciprocate in the up-down direction synchronously, so as to open or close the filling opening 103.

It is noted that the sealing mechanism between the piston 51 and the piston chamber 101 is equivalent to the sealing mechanism between the lower valve seat 6 and the connecting pipe 112, and a sealing space is reserved for the reciprocating motion.

The piston 51 is provided with a control block 511 in the upper piston chamber 101, and an elastic member 52 is provided between the upper chamber and the inner wall of the upper valve seat 5, and the direction of the elastic force is in the up-down direction.

In this embodiment, the elastic member 52 is preferably a spring, which is provided on the control block 511.

Specifically, the spring acts on the inner walls of the piston 51 and the upper valve seat 5 at the same time, so as to press down the piston 51, thereby realizing the sealing of the filling opening 103 by the sealing plug 11.

Of course, the elastic member 52 is not limited to a spring, and any structure capable of achieving return under the action of elastic force, such as elastic rubber, can achieve this effect.

In the linkage, the upper side of the piston 51 is connected to the gas injection back pressure assembly 200 after passing through the upper valve seat 5 by an adjusting rod 53.

As shown in fig. 3 and 4, the gas injection back pressure assembly 200 includes the back pressure pipe 7 and the gas injection back pressure head 8 that extend through the valve body structure 100. The lower side of the gas injection back pressure end is connected with the back pressure pipe 7, and the gas injection back pressure end 8 and the gas path connecting end 9 are respectively provided with a solenoid valve structure for on-off control of the valve body structure 100.

On the whole control mechanism, an electronic valve control mechanism is adopted, and the electronic valve control mechanism is an inevitable component for realizing automatic production line filling.

In a specific structure, the gas injection back pressure end 8 is connected with the adjusting rod 53 through an adjusting block 83.

In the back pressure setting, the sealing plug 11 is penetrated by the back pressure pipe 7 with a hollow inside, the back pressure pipe 7 is communicated with the gas injection back pressure end head 8, and the gas injection back pressure end head 8 is provided with a gas injection valve 81 and a back pressure valve 82.

The gas injection valve 81 is used for injecting gas into the bottle body, and carbon dioxide is used as the gas in this embodiment.

The back pressure valve 82 controls the liquid level and back pressure in the bottle.

The working principle of the air injection back pressure assembly is that when the piston 51 moves, the air injection back pressure assembly 200 is driven to reciprocate in the vertical direction synchronously, the back pressure pipe 7 is located in the bottle body, and the air injection back pressure end 8 is fixed with the back pressure pipe 7 due to the fact that the adjusting block 83 is fixed with the air injection back pressure end 8, and the back pressure pipe 7 penetrates through the piston 51 and the sealing plug 11 to form an independent air path structure. The position of the adjusting block 83 on the adjusting rod 53 can be considered, and the height of the lower end of the back pressure pipe 7 can be adjusted. The height of the lower end of the back pressure pipe 7 is a set reference of the liquid level in the bottle.

That is, this structure realizes the liquid level adjustment of the filling valve, which is adjusted to the distance between the bottom of the back pressure pipe 7 and the filling port 103 on the lower valve seat 6.

Specifically, in the filling process, the piston 51 is pneumatically lifted in the on state of the first electromagnetic valve 10, so that the sealing plug 11 is separated from the filling port 103, the filling port 103 is in an open state, and materials are quickly filled into the bottle after entering the filling cavity 102 through the feeding pipe 13;

A split umbrella 71 sleeved on the back pressure pipe 7 reflects the liquid material to the bottle wall and downwards along the bottle wall along the downstream direction;

after canning, the pressure release valve 96 is opened to increase the pressure in the bottle, so that the materials above the back pressure pipe 7 in the bottle can upwards enter the back pressure valve 82 through the back pressure pipe 7 to recover the redundant materials, and the liquid level can be ensured to be consistent, and the liquid level position is the end part of the back pressure pipe 7.

Because the residual materials of the back pressure pipe 7 can be removed during back pressure, the materials can be recovered, so that the loss of the materials is reduced, and carbon dioxide cannot be wasted on blowing the residual materials in the back pressure pipe.

The filling valve does not adopt any metering assistance (such as a flowmeter, a probe and the like), can effectively and accurately control the liquid level, and greatly reduces the purchasing cost and the maintenance cost.

As shown in fig. 1 and 5, the feed port 104 is connected with the feed pipe 13 to fix the gas path connection end 9.

In this embodiment, the feeding pipe 13 is a straight steel pipe, and the feeding pipe 13 may be L-shaped or have other shapes that can satisfy the feeding function.

When the angle of the valve body structure 100 corresponding to the gas path connecting end 9 on the production line is special, the polyethylene pipe is preferable in material selection of the feeding pipe 13, and can adapt to the arrangement of the stations of the complex production line.

It should be noted that, the inlet pipe 13 that this scheme provided can be right gas circuit link 9 is relative the position of valve body structure 100 changes, satisfies the position demand of different production lines, simultaneously, on overall structure's design, the material is with the whole pipeline separation control of using of gas when this solenoid valve filling, mutually independent is applicable to and contains gas, non-gas drink, and this valve does not have the cleaning dead angle.

And, because the structure is retrenched and the integrated level is high, the efficiency is improved by more than 200% compared with the traditional mechanical valve during CIP (on-line cleaning).

The gas path connecting end 9 comprises a three valve seat 91, the three valve seat 91 is sleeved outside the feeding pipe 13, the upper end of the three valve seat is connected with a three valve cover plate 92, the three valve seat 91 is communicated with a lower side gas transfer block 94 through a gas inlet plate 93, and a gas outlet of the gas transfer block 94 is communicated with the gas pipe plug 12.

In a specific structure, the three valve seats 91 are provided with a vacuum valve 95, a pressure release valve 96 and an exhaust valve 97. The three valves on the three valve seat 91 are communicated with the lower side gas switching block 94 through the gas inlet plate 93, the gas outlet of the gas switching block 94 is communicated with the gas pipe plug 12, and the gas pipe plug 12 is communicated with the filling cavity 102.

Specifically, the air pipe plug 12 is embedded into the filling cavity 102, after the air pipe plug 12 is embedded, a cavity is formed between the air pipe plug 12 and the air pipe, when the air pipe plug is in operation, the bottle mouth of the bottle body is positioned at the bottle body connecting end, and the bottle body is lifted up through the lifting structure matched with the filling valve, so that the bottle body is pressed against the filling opening 103. When the air injection valve 81 is opened, air is converged into the cavity through the air pipe plug 12 and then rushed into the bottle body through the air pipe in the filling cavity 102, and when the vacuum valve 95 is opened, the air flow direction is twisted.

In this embodiment, the air pipe plug 12 is directly connected to the bottle body, which is an air pipe, and is normally separated from the filling cavity 102.

Further described in connection with its mechanism of use:

The fixed connection end is first fixed to the valve body structure 100 through the feed pipe 13, and the air pipe plug 12 is inserted into the valve body structure 100.

The bottle is pressed against the filling opening 103 by a preliminary vacuum treatment.

All valves are closed, vacuum valve 95 is opened, and more than 90% of the air in the bottle is evacuated.

The carbon dioxide cleaning is then performed, the vacuum valve 95 is closed, the gas injection valve 81 is opened, and the carbon dioxide in the carbon dioxide storage area communicating with the gas injection valve 81 is rapidly flushed into the bottle.

And then carrying out secondary vacuumizing.

The gas injection valve 81 was closed, and the vacuum process was repeated to reduce the gas in the bottle to less than 0.01%.

And then, performing a carbon dioxide back pressure process, closing the vacuum valve 95, opening the air injection valve 81, gradually increasing the air pressure in the bottle, closing the air injection valve 81, and opening the back pressure valve 82.

In the filling process, the piston 51 is pneumatically lifted in the conducting state of the first electromagnetic valve 10, so that the sealing plug 11 is separated from the filling opening 103, the filling opening 103 is in an open state, and materials enter the filling cavity 102 through the feeding pipe 13 and then are filled into the bottle.

The split umbrella 71 sleeved on the back pressure pipe 7 reflects the liquid material to the bottle wall and downstream flows down along the bottle wall.

As the liquid level rises, carbon dioxide in the bottle flows back through the back pressure pipe 7 at the back pressure valve 82.

When the liquid surface touches the back pressure pipe 7, the gas in the bottle cannot flow back, and the filling is finished, at this time, the first electromagnetic valve 10 withdraws the gas pressure, the piston 51 is back pressed under the action of the elastic piece 52, and the sealing plug 11 plugs the filling opening 103.

And then standing to ensure the time margin when the rotating speed of the filling machine changes.

Finally, the exhaust valve 97 is opened, the back pressure valve 82 and the pressure relief valve 96 are closed, the gas with pressure left at the upper part of the bottle is discharged through the exhaust valve 97, the pressure in the bottle is slowly removed, and the gushing is prevented.

After pressure relief, the bottle is lowered and left off the filling valve.
