Description

Lever type purge valve device of flow regulator {LEVER TYPE PUZZY VALVE APPARATUS OF FLOWREGULATOR}

The present invention relates to a lever-type purge valve device of a flow controller used in a vending machine selling carbonated beverages, and in particular, improves the injection property of the flow regulator body formed of a synthetic resin injection molding material, The present invention relates to a lever type purge valve device of a flow regulator that prevents the strength from being lowered and easily opens and closes the valve and prevents the connection from being broken by an excessive locking force when the valve is closed.

In general, the flow regulator used in the vending machine that sells carbonated beverages is a rotary screw to discharge the air inside the main body of the beverage because the amount of syrup of the beverage can be changed if the air inside the main body is discharged with the syrup during the beverage sales. The type purge valve is adopted.

In addition, the assembly structure of the rotary screw-type purge valve has a main body formed of a synthetic resin injection molding material, and a structure in which a screw is screwed into a protrusion formed on the main wall of the main body and the purge valve body to be screwed in a rotary manner. When the valve is locked, the purge valve body is screwed and locked.

However, the conventional rotary screw-type purge valve has problems such as shape change and strength deterioration during injection, inconvenience in opening and closing the valve, and damage to the connection part due to excessive locking force when closing the valve.

Hereinafter, the conventional purge valve device will be described with reference to the drawings.

1 is a longitudinal cross-sectional view showing the configuration of a lever-type purge valve device of a conventional flow regulator, as shown in the lower case 2 through the O-ring 4 at the lower side of the main body 1 containing the syrup. The suction pipe (3) is coupled to the central portion of the body (1), the flow rate adjusting screw (6) is coupled to the cap (5) coupled to the upper end of the body (1) via the O-ring (7) have. In addition, a guide 9 is coupled to the inside of the cap 5, and a spur 10 is coupled to the inside thereof so as to be liftable, and a spring is provided between the flow rate adjusting screw 6 and the bottom surface of the spur 10. (8) is combined.

In addition, a purge valve 11 is screwed into the threaded portion 11a via an O-ring 12 to the flow pipe 1a provided on the upper side of the main body 1, and the inner end of the purge valve 11 is sealed. (13) is attached.

In the conventional lever-type purge valve device of the flow regulator, when the syrup is injected from the lower case 2 into the main body 1 containing the syrup, it is not leaked to the outside by the O-ring 4, and is filled inside the main body 1. The air, which is lighter than the syrup in the main body 1, rises to the upper end of the main body 1, and is pressed by the syrup.

In addition, when the carbonated beverage is sold, the syrup inside the main body 1 flows through the through holes of the upper guide 9 and the spur 10 through the suction pipe 3 of the main body 1. If the amount of syrup is increased or decreased, the flow rate is adjusted by turning the flow rate adjusting screw 6 coupled to the cap 5, and turning the flow rate adjusting screw 6 to the vertical movement of the flow rate adjusting screw 6. The flow rate is controlled by the compressive strength of the spring 8 to be changed.

On the other hand, the air remaining inside the main body 1 must be discharged because the syrup amount of the beverage can be changed if it exits through the suction pipe (3) at the time of sale. To this end, if the purge valve 11 which is blocked from the outside by the packing 13 is turned counterclockwise, as the passage is opened, the syrup and air filled in the main body 1 are discharged and the O-ring of the purge valve 11 is removed. It is discharged to the purge tube 14 without flowing to the outside by the (12).

The lever type purge valve device of the conventional flow regulator as described above has a threaded portion 11a of the purge valve 11 and a corresponding body 1 for discharging air filled in the injection molding body 1. Since the tapping process should also be performed on the inner circumferential surface of the distribution pipe 1a, there was a problem in that the productivity was lowered.

In addition, since the distribution pipe 1a of the main body 1 protrudes greatly from the main body 1 and a stress due to processing is accumulated in the distribution pipe 1a during secondary processing for tapping, After filling the syrup, if the purge valve 11 is turned clockwise to block the discharge, excessive force is applied, which may cause damage. In the case of injection molding the main body 1, the part protruding largely from the main body 1 is different from the main body 1 in the contracted form when cooled immediately after the injection, so that the shape is distorted and the inner surface, that is, the O-ring 12 contacts Unevenness may occur on the inner circumferential surface, and a problem of weakening of strength may be caused, and thus a lot of cooling time must be given, thus requiring a lot of injection manufacturing time, and thus there is a problem of lowering productivity.

The present invention devised to solve the above problems and defects as described above, to improve the injection properties of the flow regulator body formed of a synthetic resin injection molding material, and to prevent the shape change and strength degradation caused during injection, It is to provide a lever-type purge valve device of the flow regulator to easily open and close the valve and to prevent the connection portion is broken by an excessive locking force when the valve is closed.
