Description

Technical Field

[0001] This utility model belongs to the field of liquid filling technology, and in particular relates to a liquid filling valve device. Background Technology

[0002] Filling is the process of putting materials into containers, which can be liquids, powders, granules, etc. Containers can be bottles, bags, drums, boxes, etc. Currently, the filling and sealing methods used in similar products on the market are: UN oil seal + squeeze seal, UN oil seal + wall seal, and combined oil seal + squeeze seal. UN oil seal + squeeze seal: This refers to using a UN oil seal to seal the movable filling rod and a squeeze seal (using O-rings or PTFE) to seal the filling head. The disadvantage is that over time, leakage is likely to occur with the UN oil seal, and the UN oil seal is not very versatile; it is easily corroded by strong acids, alkalis, and pesticides. Additionally, squeeze seals using O-rings are prone to corrosion, while PTFE squeeze seals are less susceptible to corrosion and have greater versatility. Furthermore, the dispensing nozzle has no fixed design. The guide valve makes the liquid column unfocused and prone to tilting; UN oil seal + wall seal: This refers to a seal using a UN oil seal with the movable filling rod and an O-ring seal with the filling head. The disadvantage is that the UN oil seal is prone to leakage over time, and the UN oil seal is not very versatile, easily corroded by strong acids, alkalis, and pesticides. In addition, the O-ring used for the wall seal is also prone to corrosion; Combination oil seal + squeeze seal: This refers to a seal using a combination oil seal (PTFE) with the movable filling rod and a squeeze seal (either O-ring or PTFE) with the filling head. The disadvantage is that the lack of a guide valve makes the liquid column unfocused and prone to tilting, and the PTFE seal is relatively versatile due to its corrosiveness.

[0003] However, it still has the following drawbacks in practical use:

[0004] 1. The existing liquid filling valve device's filling and sealing method, due to the lack of a certain guide at the outlet, results in an uneven liquid column that is prone to tilting.

[0005] 2. Existing liquid filling valve devices are prone to liquid residue buildup after filling, causing liquid to drip onto the items. To address this problem, we provide a liquid filling valve device. Utility Model Content

[0006] The purpose of this utility model is to provide a liquid filling valve device. By adding a guide nozzle to the original PTFE seal, the water column of the discharge is more concentrated. The design is reasonable, stable, and reliable. In addition, by using the filling rod and vacuum back suction hole, when the valve is fully closed, there will be some liquid hanging on the wall. The filling nozzle is equipped with a vacuum back suction hole. The vacuum generator can draw away the liquid in the cone part of the PTFE stopper through the back suction inside the filling rod, preventing it from dripping onto the item.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a liquid filling valve device, including a support base and a valve opening cylinder installed on top of it. A filling valve body is arranged directly below the support base. A filling nozzle is threadedly sleeved on the bottom of the outer wall of the filling valve body. A long guide tube is provided at the bottom end of the filling nozzle. A sealing PTFE gasket is snapped on the top of the filling nozzle. A filling rod is installed inside the filling valve body. A vacuum back suction hole is opened on the top of the outer wall of the filling rod.

[0009] The present invention is further configured such that a branch pipe is provided above the outer wall of the filling valve body, and a fixing ring is fixed above the inner wall of the filling valve body.

[0010] The present invention is further configured such that an adjusting and fixing flange is slidably inserted into the top of the filling valve body, and a quick-release clamp is sleeved on the outside of the joint between the support base and the adjusting and fixing flange.

[0011] The present invention is further configured such that a combined sealing ring is stacked on the upper surface of the fixing ring, and a compression spring is provided above the combined sealing ring.

[0012] The present invention is further configured such that the compression spring is located between the bottom of the adjusting fixed flange and the top of the combined sealing ring, and the telescopic end of the valve opening cylinder is connected to the top of the filling rod through a movable joint.

[0013] The present invention is further configured such that a filling guide ring is welded to the bottom of the outer wall of the filling rod, and the filling guide ring is slidably installed on the inner wall of the filling valve body.

[0014] The present invention is further configured such that a PTFE plug is threaded onto the bottom of the outer wall of the filling rod, and a blocking flat gasket is provided on the top of the PTFE plug.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model adds a guide nozzle to the original PTFE seal, making the water column more concentrated. The design is reasonable, stable and reliable, solving the problem that the existing liquid filling valve device's filling sealing method causes the liquid column to be unconcentrated and prone to tilting due to the lack of a certain guide nozzle.

[0017] 2. This utility model, by setting a filling rod and a vacuum back suction hole, solves the problem that liquid may stick to the wall after filling when the valve is fully closed. The filling nozzle is equipped with a vacuum back suction hole, which allows the liquid to be drawn away from the cone part of the PTFE stopper by the vacuum generator through the inside of the filling rod, preventing it from dripping onto the item. This solves the problem that existing liquid filling valve devices are prone to liquid sticking to the wall after filling, causing liquid to drip onto the item. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 3This utility model is a liquid filling valve device, including a support base 100 and a valve opening cylinder 101 installed on its top. A filling valve body 102 is arranged directly below the support base 100. A filling outlet 200 is threadedly sleeved on the bottom of the outer wall of the filling valve body 102. A long guide tube 201 is arranged at the bottom end of the filling outlet 200. A sealing PTFE gasket 202 is snapped onto the top of the filling outlet 200.

[0027] Specifically, a branch pipe 102a is provided on the upper part of the outer wall of the filling valve body 102, and a fixing ring 102b is fixed on the upper part of the inner wall of the filling valve body 102; an adjusting fixing flange 104 is slidably inserted into the top of the inner part of the filling valve body 102, and a quick-release clamp 103 is sleeved on the outer side of the joint between the support seat 100 and the adjusting fixing flange 104; a combined sealing ring 106 is stacked on the upper surface of the fixing ring 102b, and a compression spring 105 is provided on the upper part of the combined sealing ring 106; the compression spring 105 is located between the bottom of the adjusting fixing flange 104 and the top of the combined sealing ring 106, and the telescopic end of the valve opening cylinder 101 is connected to the top of the filling rod 300 through a movable joint 107.

[0028] Furthermore, the valve opening cylinder 101 and the filling rod 300 are connected by a movable joint 107, which plays a role in fine-tuning the concentricity. The support base 100 and the adjusting and fixing flange 104 are installed by a quick-release clamp 103. In order to ensure concentricity, there is a concentric positioning step between the two. The adjusting and fixing flange 104 presses the compression spring 105 onto the combined sealing ring 106 by means of threads, so that the combined sealing ring 106 is tightly fitted with the filling rod 300 and the filling valve body 102, ensuring that there is no leakage when the filling rod 300 moves. The sealing PTFE gasket 202 can play a sealing role.

[0029] The operation process of this embodiment is as follows: the valve opening cylinder 101 is activated, and its telescopic end retracts to pull the filling rod 300 through the movable joint 107. After the filling rod 300 is pulled up, the PTFE plug 303 at its bottom end will move upward synchronously. At this time, the outlet of the filling nozzle 200 is opened, realizing the purpose of opening and closing the filling valve device. Due to the pressure of the compression spring 105 and the adjusting fixed flange 104, the PTFE combination oil seal is always kept in close contact with the filling rod 300. When the filling valve device is closed, the pressure of the valve opening cylinder 101 will press the PTFE plug 303 tightly onto the filling nozzle 200. In addition, the filling nozzle 200 has a long guide, which allows the columnar liquid at the filling point to be concentrated during the filling process.

[0030] Example 2

[0031] Please see Figure 3Based on Embodiment 1, the difference from the first embodiment is that a filling rod 300 is provided, and a vacuum back suction hole 301 is provided on the top of the outer wall of the filling rod 300, which solves the problem that liquid tends to stick to the wall after filling in the existing liquid filling valve device, causing liquid to drip onto the item.

[0032] Specifically, a filling guide ring 302 is welded to the bottom of the outer wall of the filling rod 300, and the filling guide ring 302 is slidably installed on the inner wall of the filling valve body 102; a PTFE plug head 303 is threaded onto the bottom of the outer wall of the filling rod 300, and a blocking flat gasket 303a is provided on the top of the PTFE plug head 303.

[0033] Furthermore, the filling guide ring 302 plays a guiding role when the filling rod 300 moves up and down. The filling rod 300 and the PTFE plug 303 are fixed together by threads, and the blocking flat washer 303a prevents the PTFE plug 303 from being deformed due to excessive force.

[0034] The operation process of this embodiment is as follows: When the filling valve device is completely closed, there will be some hanging on the wall. Therefore, a vacuum back suction hole 301 is provided on the filling rod 300. The liquid in the cone of the PTFE stopper 303 can be sucked away by the vacuum generator through the inside of the filling rod 300 to prevent it from dripping onto the item.
