Description

Technical Field

[0001] This utility model relates to the field of liquid storage devices, and in particular to a liquid bag with a detachable control valve. Background Technology

[0002] Liquid bags, as storage containers for liquids, are commonly used in daily life and industrial applications. A typical liquid bag consists of a bag body and a spout located on one side of the bag body. To seal the liquid bag, an outer cap is usually provided on the spout. The cap is generally threaded onto the outer circumference of the spout. When the liquid inside the bag needs to be poured out, the cap is unscrewed; when not in use, the cap is screwed back onto the spout for a sealed storage. However, when the cap is opened, the liquid bag cannot be inverted, otherwise the liquid will overflow. Furthermore, when pouring liquid from the bag, the flow cannot be restricted.

[0003] To address the shortcomings of existing technologies, CN211443338U discloses a liquid bag valve, but this liquid bag valve is a single-use device that cannot be reused, resulting in resource waste. Utility Model Content

[0004] The main objective of this invention is to provide a liquid bag with a detachable control valve, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A liquid bag with a detachable control valve includes a liquid outlet housing, which includes a connecting device and a flow control device. The liquid outlet housing also includes a base with external threads, and a base fixing member is threadedly connected to the base. The base fixing member has internal threads and is fixedly connected to a bag body. The flow control device includes a liquid outlet valve and a support member. The liquid outlet valve is fixedly connected to an elastic silicone rubber, and a sliding block is fixedly connected to the other end of the elastic silicone rubber. The support member has sliding openings on both sides, and the sliding blocks cooperate with the sliding openings. A limit block is fixedly connected to one end of the liquid outlet valve connected to the support member, and a limit block is also fixedly connected to one end of the support member connected to the liquid outlet valve. A clamping device is fitted between the limit blocks.

[0006] Furthermore, the sliding block includes a connecting block and a force-bearing block. The connecting block is fixedly connected to the elastic silicone, and the force-bearing block cooperates with the sliding opening to move the sliding block.

[0007] Furthermore, the liquid outlet housing also includes a base, the base has external threads, the base is threadedly connected to a base fixing component, the base fixing component has internal threads, and the base is also fixedly connected to a sealing ring to increase the sealing performance of the equipment.

[0008] Furthermore, the clamping device includes an upper limit ring and a lower limit ring. One end of the upper limit ring is fixedly connected to a threaded post, and one end of the lower limit ring has a movable hole. The threaded post is fitted with a locking cap. The threaded post and the movable hole cooperate to realize the connection between the support and the liquid outlet valve.

[0009] Compared with existing liquid bag control valve technology, this utility model has the following advantages: In this invention, the clamp device enables the disassembly and installation of the entire control valve, allowing the valve to be reused repeatedly. After use, residual liquid inside can be effectively cleaned, and any damaged parts can be replaced for continued use. It also has good sealing properties and is more environmentally friendly and has lower operating costs compared to disposable control valves. Attached Figure Description

[0011] The present invention will be further described below with reference to specific embodiments. However, it should be noted that the embodiments are implemented under the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0012] like Figure 1-4As shown, a liquid bag with a detachable control valve includes a liquid outlet housing 1. The liquid outlet housing 1 includes a connecting device 2 and a flow control device 3. The flow control device 3 includes a liquid outlet valve 31 and a support member 32. The liquid outlet valve 31 is fixedly connected to an elastic silicone 33. The other end of the elastic silicone 33 is fixedly connected to a sliding block 34. The support member 32 has sliding openings 35 on both sides. The sliding block 34 cooperates with the sliding opening 35. The liquid outlet valve 31 is fixedly connected to a limiting block 36 at one end connected to the support member 32. The support member 32 is also fixedly connected to a limiting block 36 at one end connected to the liquid outlet valve 31. The limiting blocks 36 are connected to each other by a clamping device 37.

[0013] The sliding block 34 includes a connecting block 341 and a force-bearing block 342. The connecting block 341 is fixedly connected to the elastic silicone 33. The force-bearing block 342 cooperates with the sliding port 35. The liquid outlet housing 1 also includes a base 4. The base 4 is provided with external threads. The base 4 is threadedly connected to a base fixing member 41. The base fixing member 41 is provided with internal threads. The base 4 is also fixedly connected to a sealing ring 42. The clamping device 37 includes an upper limit ring 371 and a lower limit ring 372. One end of the upper limit ring 371 is fixedly connected to a threaded post 373. One end of the lower limit ring 372 has a movable hole 374. The threaded post 373 is fitted with a locking cap 375. The threaded post 373 cooperates with the movable hole 374.

[0014] In practical use, when not in use, the elastic silicone 33 closes the outlet of the liquid valve. When needed, the sliding block 34 slides along the sliding port 35 on the support 32. The sliding block 34 drives the elastic silicone 33 to open the outlet of the liquid valve 31, allowing the liquid to flow out. After releasing, the elastic silicone 33 returns to its original position and closes the opening. When a bag of liquid is used up, the valve is removed, and the locking cap 375 is unscrewed. The upper limit ring 371 and the lower limit ring 372 can then be opened, and the support 32 and the outlet valve 31 can be disassembled. After disassembly, all internal parts can be cleaned before use on the next bag of liquid. When internal parts of the valve are damaged or the elasticity of the elastic silicone 33 decreases, resulting in poor sealing, it can also be disassembled and replaced in this way.

[0015] The preferred embodiments of this utility model have been described in detail above, but this does not limit the patent scope of this utility model. All equivalent structural changes made under the concept of this utility model and using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
