Description

Technical Field

[0001] The utility model relates to the technical field of beverage production equipment, in particular to a filling valve for accurately controlling PE filling liquid level. Background Art

[0002] When bottled beverages are produced, liquids need to be filled into plastic bottles through canning machines. When filling existing beverages, the filling valves on the filling machines directly extend the valve stem from the bottle mouth into the beverage bottle for filling. Although it can meet the needs, the existing filling valve stem is easy to shake when it is inserted into the beverage bottle, causing the bottle to be skewed, which in turn makes the feeding unstable, causing the liquid level in the bottle to fluctuate, resulting in a liquid loss rate of more than 8%, a net content range of more than 10g, and a large number of defective products, resulting in huge cost losses.

[0003] In order to solve this problem, the utility model is produced. Utility Model Content

[0006] A further improvement is that it also includes a connecting block, which is sleeved on the valve stem, a placement groove is opened on the upper end of the valve seat, the connecting block is arranged in the placement groove, the valve seat is provided with an anti-detachment device for preventing the connecting block from detaching from the placement groove, and a sealing device is also provided between the valve stem and the connecting block.

[0007] A further improvement is that the anti-dropout device is an elastic buckle ring, an anti-dropout groove is arranged around the valve stem, one end of the elastic buckle ring is buckled on the anti-dropout groove, and the other end of the elastic buckle ring resists the valve seat.

[0008] A further improvement is that: a clamping groove is provided on the connecting block and located inside the valve seat, and a clamping block is provided on the valve stem, and the clamping block is arranged in the clamping groove.

[0009] A further improvement is that a limiting plate is provided at the bottom of the valve stem, and the limiting plate can resist the bottom of the valve sleeve.

[0010] A further improvement is that: the elastic member is a spring, the spring is sleeved on the valve seat, one end of the spring resists the valve seat, and the other end of the spring resists the valve sleeve.

[0011] A further improvement is that the sealing member comprises a breathable rubber sealing ring and a sealing rubber sealing ring, the breathable rubber sealing ring and the sealing rubber sealing ring are sleeved on the valve sleeve and located at the end of the valve sleeve, and the breathable rubber sealing ring is located above the sealing rubber sealing ring.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] The structure is simple, the filling effect is good, and the yield rate is high. The guide block limits the vertical sliding of the valve stem so that the valve stem will not shake or tilt, and the bottle will not be tilted by the valve stem, ensuring that the valve stem is always vertically downward and perpendicular to the bottle mouth, so that the material can be discharged stably without causing material loss and improving the yield rate.

[0017] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1-2The embodiment of the utility model discloses: a filling valve for accurately controlling the filling liquid level of PE, comprising a valve seat 1, a valve sleeve 2 is slidably penetrated on the valve seat 1, a spring 4 is arranged between the valve seat 1 and the valve sleeve 2, the spring 4 is sleeved on the valve seat 1, one end of the spring 4 resists the valve seat 1, and the other end of the spring 4 resists the valve sleeve 2, a valve stem 3 for filling is arranged between the valve seat 1 and the valve sleeve 2, a breathable rubber sealing ring 9 and a sealing rubber sealing ring 8 are arranged at the bottom of the valve sleeve 2, the breathable rubber sealing ring 9 and the sealing rubber sealing ring 8 are sleeved on the valve sleeve 2 and located at the end of the valve sleeve 2, the breathable rubber sealing ring 9 is located above the sealing rubber sealing ring 8, three guide blocks 10 are arranged around the valve stem 3, the guide blocks 10 resist the inner wall of the valve sleeve 2, so that the valve stem 3 can slide out of the valve sleeve 2 vertically. When the beverage bottle is filled, the filling valve moves to the mouth of the beverage bottle to resist. At this time, the valve sleeve 2 extends into the interior of the beverage bottle and mortgages the bottle mouth. The valve sleeve 2 slides into the valve seat 1, the spring 4 is compressed, and the valve stem 3 extends out and is located in the beverage bottle to fill the bottle with liquid. Under the action of the guide block 10, the vertical sliding of the valve stem 3 is restricted so that the valve stem 3 will not shake or tilt, and the bottle will not be tilted by the valve stem 3, ensuring that the valve stem 3 is always vertically downward and perpendicular to the bottle mouth, so that the material can be stably discharged without causing material and liquid loss, thereby improving the yield rate.
