Abstract

PURPOSE:To simplify the opening and closing mechanism of a flow valve in a liquid charging valve in which a reverse siphon is formed in the liquid path in order to facilitate charging of a beverage including fruits pulp. CONSTITUTION:A valve seat 9 is equipped at the bottom of a liquid path 8 of a charging valve body 1 and made so as to open or close a flow valve 10 and further, the circulating path of a reverse siphon 14 is formed in the liquid path 8 above the valve seat 9 so as to adjust the opening or closing of the flow valve 10 regardless of the reverse siphon 14.

FIELD OF THE INVENTION This invention relates to improvements in liquid fill valves.

2. Description of the Related Art In a back pressure type liquid filling valve, as shown in Japanese Patent Publication No. 36-2050, an annular recess is formed in an upper portion of a valve base portion of the filling valve, and a valve closing element can be vertically moved in an upper portion thereof. And a section U formed by the lower edge of the valve closing element and the annular recess when the valve closing element is raised.
After circulating the letter-shaped portion, a reverse siphon portion is formed at the outflow portion of the liquid flow passage so that the reverse siphon portion is filled down into the container from the flow passage of the valve base portion, and a beverage containing coarse fruit pulp such as orange crush. Is known to facilitate the filling of

[0003]

However, in the above-mentioned reverse siphon system, since the reverse siphon portion is formed by the valve closing element and the fluid passage, the valve closing is performed in order to adjust the filling flow rate according to the viscosity of the beverage. When the opening degree of the element is changed, the reverse siphon section also has to be changed, which makes it very difficult to control the filling flow rate of the beverage. In view of these circumstances, the present invention makes it possible to easily adjust the filling flow rate of the beverage when the beverage containing the fruit pulp is filled using such an inverse siphon portion without affecting the inverse siphon portion. It is an object of the present invention to provide a fluid-filled valve according to the above.

[0004]

In order to achieve the above object, the present invention provides a valve seat at a lower end portion of a liquid flow passage of a filling valve body, and the valve seat is provided with a flow valve which projects downward to open and close. In the liquid filling valve adapted to fill the liquid by means of the above, a reverse siphon circulation portion is formed above the valve seat of the liquid flow passage. It is preferable that a vent tube that projects downward is provided at the center of the filling valve body, and the flow valve is opened and closed in conjunction with the vent tube.

[0005]

In the present invention, the filling liquid is circulated through the reverse siphon portion formed in the liquid flow passage of the filling valve body and is filled into the container from the valve seat by the opening of the flow valve, and the flow rate adjustment due to the viscosity of the liquid is reversed. It can be performed only by adjusting the opening of the flow valve without affecting the flow rate of the siphon section, and the flow path in the reverse siphon section is always kept constant.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.
The valve body 1 of the rotary liquid filling machine includes a valve base body 3 fixed to a rotary plate 2 as is well known, and a sliding member which is slidably fitted to a lower portion of the valve base body by an elevating mechanism 4. The sliding pad 5 is provided with a seal pad 6 that abuts against the rim of the filling container A.

A vent tube 7 having a float valve 7'at its lower end is provided at the central portion of the valve base 3 so as to be able to project downward, and the valve base 3 is formed at the outer peripheral portion of the lower end of the vent tube 7. Flow valve 10 that opens and closes a gap with the valve seat 9 provided at the lower end of the liquid flow passage 8
Is provided so as to project downward, and the flow valve 10
Is a flow valve stay 11 fitted in the vent tube 7.
As is well known, the valve seat 9 is opened and closed in conjunction with the operation of the vent tube 7 to fill the filling container A with the liquid in the liquid flow passage 8.

However, above the valve seat 9 in the lower portion of the liquid flow passage 8 of the filling valve base 3, an annular recess 12 and an annular projecting edge 13 which is inserted into the annular recess 12 from above are formed in a U-shaped cross section. The reverse siphon portion 14 is formed, and the liquid is circulated through the siphon portion 14 and then filled through the valve seat 9. In the figure, reference numeral 15 is a known pressurized gas introduction hole provided in the valve base 3, 16 is a snift conduction hole, 17 is an operation cam of the lifting mechanism 4, and 18 is a tank communication hole.

Since the embodiment of the present invention is constructed as described above, when the filling valve body 1 rotates during filling,
After the sliding cylinder 5 is lowered by the lifting mechanism regulated by the actuating cam 16 and its seal pad 6 is brought into contact with the rim of the filling container A, the vent tube 7 is lowered as usual and then the flow valve 10 is opened. Then, a liquid such as a beverage containing fruit pulp flows down the fluid flow passage 8 and is filled in the filling container A. When the filling liquid level rises by such a filling action, the float valve 7'closes the vent tube 7, and then the flow valve 10 moves upward to close the valve seat 9 to complete the filling action. Before the filling operation, the pressurized gas is supplied from the pressurized gas introduction hole 15 into the filling container A and the air is removed from the sniff communication hole 16 in the air inside the filling container A before the filling operation. Is no different from conventional.

However, even when the opening degree of the flow valve 10 with respect to the valve seat 9 is arbitrarily changed in order to adjust the filling flow rate by the viscosity of the liquid to be filled, the flow passage of the reverse siphon portion 14 is always formed to be constant. Therefore, by adjusting the opening of only the flow valve 10, the filling flow rate can be adjusted without affecting the flow rate of the reverse siphon unit 14.

[0011]

According to the present invention, in order to facilitate the filling of a beverage containing fruit pulp, a reverse siphon portion is formed in the liquid flow passage of the filling valve body so that the beverage can be circulated. Since the siphon part is formed in the liquid flow passage that is not related to the opening / closing operation of the flow valve,
Even if the operating direction and the opening of the flow valve are arbitrarily changed, the reverse siphon section is always formed to be constant. Therefore, the filling flow rate can be easily and easily adjusted by adjusting the opening of only the flow valve.
