Description

Technical Field

[0001] This application belongs to the field of binary packaging technology, specifically relating to a novel high-sealing double-headed double-bag binary packaging valve. Background Technology

[0002] In existing technologies, binary packaging valves play a crucial role in the field of material packaging. They encapsulate materials within a bag, forming a sealed structure through the cooperation of the valve body and the can, isolating the material inside the bag from the propellant in both the can and the bag, ensuring pure material ejection. They also offer advantages such as fast filling speed, ease of use, and simple operation, making them widely used in the packaging of cosmetics, daily necessities, and industrial products, significantly improving product storage stability and user experience. However, current binary packaging valves on the market have some shortcomings in terms of structural design and sealing performance.

[0003] In existing technologies, a seal is required between the bladder and the valve body. However, the existing sealing structure is too simple, resulting in poor sealing performance and low assembly stability. On the one hand, during material flow and transportation, fluid is prone to overflow and direct contact with the sealing ring, accelerating its aging and deterioration, shortening its service life, and consequently reducing the overall durability and sealing stability of the packaging valve, affecting product safety and reliability. On the other hand, the bladder is prone to separating from the valve body during user operation, further reducing the overall lifespan of the binary packaging and compromising the user experience.

[0004] Therefore, in order to comprehensively improve the sealing performance of binary packaging male valves, simplify structural design, extend service life, and improve production and assembly efficiency, it is now urgent to improve them to further optimize product performance and market applicability. Summary of the Invention

[0031] Combination Figures 1 to 10The following content further illustrates the technical solution proposed in this application. This application adopts the following technical solution: a novel high-sealing double-headed double-bag binary packaging male valve, comprising a valve body X, a sealing cup Y disposed on the valve body X, and a bag assembly Z disposed on the valve body X. A first sealing mechanism 1 is provided between the valve body X and the bag assembly Z. The first sealing mechanism 1 includes a sealing seat 10 disposed on the valve body X, a connecting hole 11 disposed on the sealing seat 10, a first sealing gasket 12 disposed between the sealing seat 10 and the valve body X, and a fastening assembly 13 disposed between the connecting hole 11 and the valve body X. When the valve body X is inserted into the connecting hole 11, the valve body X is detachably connected to the sealing seat 10 via the fastening assembly 13. The bag assembly Z is disposed on the outer periphery of the sealing seat 10.

[0032] This application provides a novel high-sealing dual-head, dual-bladder, binary packaging male valve, comprising a valve body, a sealing cup disposed on the valve body, and a bladder assembly disposed on the valve body. A first sealing mechanism is provided between the valve body and the bladder assembly. The first sealing mechanism includes a sealing seat disposed on the valve body, a connecting hole disposed on the sealing seat, a first sealing gasket disposed between the sealing seat and the valve body, and a fastening assembly disposed between the connecting hole and the valve body. When the valve body is fitted into the connecting hole, the valve body is detachably connected to the sealing seat through the fastening assembly. The bladder assembly is disposed on the outer periphery of the sealing seat. By setting the first sealing mechanism, the sealing performance and assembly stability between the valve body and the bladder assembly can be significantly improved, preventing fluid overflow from contacting the sealing ring during fluid transportation, delaying the aging of the sealing ring, extending the service life of the male valve, preventing the bladder assembly from separating from the valve body, improving the user experience, and increasing production assembly efficiency. It has the advantages of simple structure, easy operation, low implementation cost, and ease of promotion and implementation.

[0033] In the actual assembly process, the first sealing gasket 12 is first pre-installed in the first mounting groove 102 of the sealing seat 10, then the valve body X is inserted along the axial direction of the connecting hole 11, and the valve body X and the sealing seat 10 are detachably fixed by the fastening assembly 13. Finally, the bag assembly Z is sleeved and fixed on the outer periphery of the sealing seat 10 to complete the overall assembly.

[0034] In actual implementation, the valve body X and the sealing seat 10 are positioned through the connecting hole 11. The first sealing gasket 12 is squeezed to form a radial sealing surface, preventing fluid from overflowing from the gap between the valve body and the sealing seat. At the same time, the fastening assembly 13 provides axial preload to ensure that the sealing gasket is always in a compressed state and to avoid loosening of the assembly.

[0035] In actual implementation, during fluid filling and ejection, the fluid in the bag assembly Z is transported through the flow channel of the valve body X. The sealing seat 10 is engaged with the valve body X and a closed-loop seal is achieved through the sealing gasket, which can prevent the bag from separating from the valve body and ensure that the fluid flows only along the preset flow channel.

[0036] In actual implementation, the inner wall of the connecting hole 11 and the surface of the fastening assembly are coated with a wear-resistant layer made of polytetrafluoroethylene (PTFE). By setting the wear-resistant layer, wear during assembly can be effectively reduced, the re-assembly accuracy of the fastening assembly can be improved, and the service life of the fastening assembly can be extended.

[0037] In this embodiment, the sealing seat 10 includes a base body 100, a connecting flange 101 disposed on one end of the base body 100 near the valve body X, and a first mounting groove 102 disposed on the connecting flange 101. The connecting hole 11 is disposed on the base body 100, and the first sealing gasket 12 is matched and disposed in the first mounting groove 102. When the valve body X is matched and extended into the connecting hole 11, the valve body X abuts against the first sealing gasket 12.

[0038] In the actual assembly process, the first sealing gasket 12 is first embedded in the first mounting groove 102 on the connecting protrusion 101. The size of the first mounting groove 102 is interference-fitted with the first sealing gasket 12 to achieve pre-fixation of the gasket and prevent displacement or detachment during assembly. Then, the valve body X is inserted along the axial direction of the connecting hole 11 on the base body 100, and the valve body is detachably installed on the base body.

[0039] Furthermore, when the valve body X is inserted to a preset depth, the fastening assembly 13 fixes the valve body X to the base body 100. The end face of the valve body X abuts tightly against the first sealing gasket 12. The axial pressure of the valve body X causes the first sealing gasket 12 to undergo elastic deformation, filling the gap between the valve body and the connecting flange, thus completing the initial sealing assembly.

[0040] During the filling and ejection of the material, the fluid pressure inside the bag assembly Z acts on the outer periphery of the sealing seat 10, while the radial positioning fit between the valve body X and the connecting hole 11 can block the leakage path of the fluid along the radial direction; under the action of fluid pressure, the first sealing gasket 12 undergoes further elastic deformation, and the end face of the first sealing gasket forms a tight sealing surface with the contact surface of the valve body X and the connecting flange 101, completely blocking the axial overflow channel of the fluid; the connecting flange 101 provides axial support for the first sealing gasket 12, avoiding excessive deformation of the gasket under high pressure and ensuring the long-term stability of the sealing structure.

[0041] In this embodiment, the valve body X includes a valve chamber 2, a connecting portion 3 located at one end of the valve chamber 2 near the bag assembly Z, a conveying hole 4 located on the connecting portion 3, a valve stem 5 located between the valve chamber 2 and the sealing cup Y, and a return spring 6 located between the valve stem 5 and the valve chamber 2. The fastening assembly 13 is located between the connecting portion 3 and the first sealing mechanism 1, and the connecting portion 3 can be matched and extended into the connecting hole 11.

[0042] In the actual assembly process, the first sealing gasket is first embedded into the first mounting groove of the sealing seat, and then the connecting part 3 of the valve body X is inserted along the axis of the connecting hole 11 of the sealing seat. The outer diameter of the connecting part 3 matches the inner diameter of the connecting hole 11 to achieve radial positioning. At this time, the fastening component 13 between the connecting part 3 and the first sealing mechanism 1 automatically fastens to fix the connecting part 3 and the sealing seat. At the same time, the end face of the connecting part 3 squeezes the first sealing gasket, causing it to elastically deform and fill the gap to form an initial seal.

[0043] Furthermore, the return spring 6 is then fitted onto the outer circumference of the valve stem 5 and installed together into the valve chamber 2. The sealing cup Y is then fixed to the outer circumference of the valve chamber 2, so that the return spring 6 is in a pre-compressed state. Under the action of the spring force, the valve stem 5 presses against the sealing surface of the valve chamber 2, blocking the passage between the valve chamber 2 and the outside, thus completing the overall assembly.

[0044] In actual implementation, when the user presses the valve stem 5, the valve stem 5 moves downward against the elastic force of the return spring 6, and the liquid inlet on the valve stem is separated from the sealing surface of the valve chamber 2, and the valve chamber 2 is in a connected state with the delivery hole 4; the material in the bag assembly Z enters the valve chamber 2 through the delivery hole 4 under the action of the propellant pressure in the tank, and is then sprayed out through the liquid inlet.

[0045] After the valve stem 5 is released, the return spring 6 releases its pre-compression force, pushing the valve stem 5 upward to return to its original position. The inlet on the valve stem then presses against the sealing surface of the valve chamber 2 again, thus preventing fluid from being ejected from the inlet.

[0046] In this embodiment, the fastening assembly 13 includes a snap-fit ​​ear 130 disposed on the inner wall of the connecting hole 11 and a snap fastener 131 disposed on the outer periphery of the connecting part 3. When the connecting part 3 is inserted into the connecting hole 11, the snap fastener 131 abuts against the snap-fit ​​ear 130 so that the valve body X is engaged with the sealing seat 10.

[0047] In this embodiment, the end of the snap-fit ​​ear 130 near the connecting part 3 is provided with a first inclined surface 132, and the end of the buckle 131 near the snap-fit ​​ear 130 is provided with a second inclined surface 133. When the connecting part 3 is inserted into the connecting hole 11, the first inclined surface 132 is used to guide the buckle 131 to the snap-fit ​​ear 130.

[0048] In this embodiment, the connecting part 3 is provided with a slot 134 above the buckle 131. The end of the slot 134 away from the buckle 131 is provided with a third inclined surface 135. When the connecting part 3 is inserted into the connecting hole 11, the buckle 131 abuts against the bottom of the snap ear 130, and the third inclined surface 135 fits against the second inclined surface 133.

[0049] In actual implementation, when the connecting part 3 of the valve body X is inserted into the connecting hole 11 of the sealing seat 10, the second inclined surface 133 of the buckle 131 contacts the first inclined surface 132 of the snap-fit ​​ear 130. Since the inclination angles of the first and second inclined surfaces match each other, the axial insertion force of the connecting part 3 is decomposed into radial elastic force through the inclined surface, which forces the buckle 131 to elastically contract towards the inside of the connecting part 3, thereby realizing blind insertion installation and improving assembly efficiency.

[0050] Specifically, the inclination angles of the first and second inclined planes are 30°-45°.

[0051] Furthermore, as the user continues to advance the connecting part 3, after the latch 131 passes the latch ear 130, the latch 131 expands radially under its own elastic restoring force, and its lower end face tightly abuts against the bottom of the latch ear 130, completing axial locking; at the same time, the third inclined surface 135 of the slot 134 on the connecting part 3 fits against the second inclined surface 133 of the latch 131, restricting the radial rebound of the latch 131 and further improving assembly stability.

[0052] During the fluid filling, ejection and storage process, the fluid pressure or external vibration of the bag assembly will generate axial separation force. At this time, the end face abutment structure of the buckle 131 and the snap ear 130 provides reverse support force to block the axial displacement of the connecting part 3 and the connecting hole 11. At the same time, the fit between the third inclined surface 135 and the second inclined surface 133 further disperses the force, avoids local stress concentration of the buckle leading to breakage, and ensures that the locking state remains stable.

[0053] In actual implementation, the entrance end of the first inclined plane 132 is provided with a rounded chamfer.

[0054] In this embodiment, the valve stem 5 includes a rod body A50 disposed between the valve chamber 2 and the sealing cup Y, an outlet A51 disposed on the rod body A50, and an inlet A52 disposed on the rod body A50 and communicating with the outlet A51. One end of the rod body A50 abuts against the return spring 6, and the other end protrudes from the sealing cup Y. The rod body A50 can move along the height direction of the valve chamber 2 so that the inlet A52 is closed or communicates with the valve chamber 2.

[0055] In the actual assembly process, the return spring 6 is first fitted onto the end of the rod A50 near the valve chamber 2. Then, the rod A50 is inserted into the axial hole of the valve chamber 2, so that one end of the return spring abuts against the inner wall of the valve chamber 2, and the other end abuts against the rod A50, forming a pre-compressed state. Subsequently, the sealing cup Y is fixed to the outer periphery of the valve chamber 2, and the end of the rod A50 away from the spring protrudes from the sealing cup Y. At this time, under the action of the spring force, the liquid inlet on the rod A50 is tightly fitted with the inner wall of the axial hole of the valve chamber 2, and the liquid inlet A52 is blocked by the inner wall of the valve chamber 2, and is in a closed state, completing the initial seal. When the user presses the end of the rod A50 protruding from the sealing cup Y, the rod A50 overcomes the spring force of the return spring 6 and moves downward along the height direction of the valve chamber 2. As the rod moves, the liquid inlet A52, which was originally blocked by the inner wall of the valve chamber 2, connects with the valve chamber, forming a fluid channel. Under the pressure of the propellant inside the tank, the fluid in the bag assembly first enters the valve chamber 2 through the conveying hole of the valve body connection, then flows into the internal flow channel of the rod A50 through the inlet A52, and finally sprays out from the outlet A51, completing the material conveying. After the rod A50 is released, the return spring 6 releases the pre-compression force, pushing the rod A50 to return to its original position along the height of the valve chamber. When the rod returns to its initial position, the inlet A52 is blocked again by the inner wall of the valve chamber 2, cutting off the fluid passage. At the same time, the sealing surface of the rod A50 is tightly fitted again with the inner wall of the axial hole of the valve chamber 2, restoring the initial sealing state and preventing fluid leakage.

[0056] In actual implementation, the reset spring is made of 316L stainless steel.

[0057] In this embodiment, the valve stem 5 also includes a limiting part 7 located on the outer periphery of the stem body A50. When the stem body A50 can move along the height direction of the valve chamber 2, the limiting part 7 abuts against the return spring 6.

[0058] In this embodiment, the limiting part 7 includes a plurality of limiting blocks 70 spaced apart around the outer periphery of the rod body A50, and a reinforcing rib 71 disposed between two adjacent limiting blocks 70.

[0059] In this embodiment, the limiting part 7 also includes an arc surface 72 disposed on the side of the limiting block 70 away from the rod body A50.

[0060] In actual implementation, the return spring 6 is sleeved on the outer periphery of the rod A50, so that one end of the return spring abuts against the inner wall of the valve chamber 2, and the other end abuts against the bottom of the limiting block 70. Multiple limiting blocks 70 arranged at intervals (3-8 evenly distributed around the circumference) together form an annular support surface, which can realize the radial positioning of the return spring and prevent the return spring from shifting during assembly.

[0061] In this embodiment, the valve body X further includes a second sealing mechanism 8 disposed between the valve chamber 2 and the valve stem 5. The second sealing mechanism 8 includes a second mounting groove 80 disposed at one end of the valve chamber 2 near the sealing cup Y, and a second sealing gasket 81 disposed in the second mounting groove 80. When the valve stem 5 is disposed on the valve chamber 2, the second sealing gasket 81 is located at the corresponding position of the liquid inlet A52 to seal the valve stem 5.

[0062] In actual implementation, when the user presses the valve stem 5, the valve stem moves downward along the height direction of the valve chamber 2, and the liquid inlet A52 moves away from the second sealing mechanism and connects with the valve chamber 2 (fluid can enter the stem flow channel through the liquid inlet); during this process, the second sealing gasket 81 is always tightly fitted to the outer periphery of the valve stem 5, enhancing the sealing surface fit and preventing fluid from overflowing from the gap between the valve stem and the valve chamber; after releasing the valve stem 5, the return spring pushes the valve stem upward to reset; when the valve stem resets to the initial position, the second sealing gasket 81 covers the corresponding area of ​​the liquid inlet, restoring the radial sealing state.

[0063] In this embodiment, the valve chamber 2 includes a valve seat 20 and a valve cavity 21 disposed on the valve seat 20. The reset spring 6 is disposed in the valve cavity 21. The valve stem 5 communicates with the valve cavity 21. The delivery hole 4 communicates with the valve cavity 21.

[0064] In actual implementation, a guide post is provided at the bottom of the valve cavity, and the bottom of the return spring is sleeved on the guide post. This can prevent the return spring from radially shifting or twisting when the valve stem is pressed; reduce friction and wear between the valve stem and the guide sleeve; and extend the service life of the return spring.

[0065] In this embodiment, a third sealing mechanism is also provided between the valve chamber 2 and the sealing cup Y. The third sealing mechanism includes a third mounting groove 90 provided between the sealing cup Y and the valve chamber 2, and a third sealing gasket 91 provided in the third mounting groove 90.

A first sealing mechanism is provided between the valve body and the bladder assembly.
