Description

Technical Field

[0001] This utility model belongs to the field of waterproof sealing of gas valves. Specifically, this utility model relates to a waterproof sealing structure for gas valves. Background Technology

[0002] Many existing gas valves lack waterproof sealing structures. Some intelligent gas valves have buttons and Type-C interfaces, which cannot be well adapted to general sealing structures. Gas valves are generally made of ABS material, and the gap between gas valves and ordinary sealing structures is relatively large, making it impossible to fit tightly. The waterproof sealing structure at the Type-C port of the valve cover is prone to leakage, resulting in poor waterproof rating and poor waterproof sealing effect.

[0003] A search revealed that Chinese patent CN221958288U, published on November 5, 2024, discloses a gas leak alarm device for a gas valve. This device includes a lower housing and an upper housing, which are bolted to the outside of the gas valve. A rotating shaft is vertically mounted through the top of the upper housing and rotatably via a seal. A screw block is located at the top of the rotating shaft, and a mounting plate is mounted at the bottom. Two limiting plates are symmetrically mounted on both sides of the mounting plate along its length. A gas concentration sensor is mounted on the top wall of the upper housing, and a controller is mounted on the outer surface of the upper housing. The gas concentration sensor is electrically connected to the controller, and a warning light and a horn are mounted on the outer surface of the controller. By mounting the lower and upper housings to the outside of the gas valve, the gas valve can be sealed. Therefore, even if a gas leak occurs, continuous leakage can be prevented, and the leak will be quickly detected by the gas concentration sensor, thus improving the detection efficiency and facilitating timely handling. However, this patent does not solve the problem of waterproof sealing. Utility Model Content

[0028] like Figure 1 As shown, a waterproof sealing structure for a gas valve includes a housing 1, a gas valve 2 disposed at the bottom of the housing 1, a waterproof mechanism 3 disposed on one side of the housing 1, and a waterproof cover 4 disposed at the top of the housing 1. By providing the waterproof mechanism 3 on one side of the housing 1 and the waterproof cover 4 on the top of the housing 1, a waterproof seal for the gas valve 2 is achieved.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the waterproof mechanism 3 includes a connecting plate 5, a first protrusion 6, and a second protrusion 7. The first protrusion 6 is disposed on the connecting plate 5, and the second protrusion 7 is disposed on the first protrusion 6. The connecting plate 5 and the housing 1 are formed by two-color injection molding. The first protrusion 6 is disposed on the connecting plate 5, and the second protrusion 7 is disposed on the first protrusion 6, forming an integral structure that serves to provide waterproofing and allows the entire waterproof mechanism 3 to be fixed to one side of the housing 1.

[0030] like Figure 6As shown, both the first protrusion 6 and the second protrusion 7 are annular protrusions. The inner diameter of the first protrusion 6 is smaller than that of the second protrusion 7. A first through hole 8 is provided on the other side of the housing 1. One end of the gas valve 2 is provided with a Type-C interface 9 that mates with the inner wall of the first protrusion 6, and the other end of the gas valve 2 is provided with a button 10 that mates with the first through hole 8. Both the first protrusion 6 and the second protrusion 7 are annular protrusions with shapes similar to the Type-C interface 9. The inner wall of the first protrusion 6 mates with the Type-C interface 9. The connecting plate 5, the first protrusion 6, and the second protrusion 7 are an integral structure with good waterproof sealing effect. The first through hole 8 is provided on the other side of the housing 1, through which the button 10 at the other end of the gas valve 2 passes. This allows for the installation of a waterproof and sealed housing 1 on the gas valve 2 without affecting its function.

[0031] The top of the housing 1 is provided with a second through hole 11. The gas valve 2 is provided with a rotating shaft 12, which passes through the second through hole 11. A handwheel 13 is provided at the end of the rotating shaft 12. The rotating shaft 12 of the gas valve 2 passes through the second through hole 11, and the handwheel 13 is provided at the end of the rotating shaft 12. This allows the gas valve 2 to be controlled by the handwheel 13 without disassembling the housing 1. In this embodiment, the gas valve 2 is a valve in the prior art.

[0032] like Figure 7 As shown, a rotating structure 14 is provided on the outside of the handwheel 13. The rotating structure 14 is provided with multiple sets of rotating grooves 15. A circular plate 16 is provided at the bottom of the waterproof cover 4. A protrusion 17 that cooperates with the rotating groove 15 is provided on the circular plate 16.

A baffle 19 that cooperates with the notch of the anti-foolproof structure 18 is provided on one side of the circular plate 16. A rotating mechanism 14 is provided on the outer side of the handwheel 13. The rotating mechanism 14 serves to fix the waterproof cover 4. The rotating structure 14 is a circular protrusion with a rotating groove 15. In this embodiment, three sets of rotating grooves 15 are provided. A circular plate 16 is provided at the bottom of the waterproof cover 4. The outer wall of the circular plate 16 is provided with three sets of protrusions 17. The protrusions 17 cooperate with the rotating grooves 15. The circular plate 16 is fixed in the rotating structure 14. A baffle 19 is provided at the notch of the circular plate 16 corresponding to the notch of the anti-foolproof structure 18. It is used to install the anti-foolproof structure 18 of the waterproof cover 4. The baffle 19 rotates to the limit position of the two notches to serve as a prompt.

[0033] The inner wall of the top of the housing 1 is provided with injection molding screw holes 20, which are connected to the gas valve 2 by bolts. Two sets of injection molding screw holes 20 are provided diagonally on the inner wall of the top of the housing 1. The injection molding screw holes 20 are connected to the circuit board on the top of the gas valve 2 by bolts, which serve to fix and support them.

[0034] The inner wall of the top of the shell 1 is provided with reinforcing ribs 21. The reinforcing ribs 21 on the inner wall of the shell 1 improve the structural strength and rigidity of the shell 1 and play a supporting and fixing role.

[0035] The bottom of housing 1 and the end of gas valve 2 are connected by bolts. The bottom of housing 1 has a screw hole for bolting to gas valve 2. The screw hole is located close to the inner wall of housing 1, which improves the sealing performance after housing 1 and gas valve 2 are connected.

[0037] The shell 1 is made of ABS plastic, the connecting plate 5 is made of TPV elastic plate, and the first protrusion 6 and the second protrusion 7 are TPV elastic blocks. The shell 1, made of ABS plastic, has good impact resistance and high strength. The connecting plate 5, the first protrusion 6 and the second protrusion 7 are made of TPV thermoplastic vulcanized rubber, which can serve as a cross-border fusion of rubber and plastic properties, combining the elasticity of rubber and the processability of plastic, so as to achieve a tight fit between the entire waterproof mechanism 3 and the shell 1.

[0038] The working principle of this utility model is as follows: The first protrusion 6 and the second protrusion 7 are both annular protrusions with shapes similar to the Type-C interface 9. The inner wall of the first protrusion 6 fits with the Type-C interface 9. The connecting plate 5, the first protrusion 6, and the second protrusion 7 are an integral structure, providing good waterproof sealing. A first through hole 8 is provided on the other side of the housing 1, through which the button 10 at the other end of the gas valve 2 passes. This allows for the installation of a waterproof and sealed housing 1 on the gas valve 2 without affecting its function. The housing 1 is made of ABS plastic, which has good impact resistance and high strength. The connecting plate 5, the first protrusion 6, and the second protrusion 7 are made of TPV thermoplastic vulcanized rubber, which can serve as a cross-border fusion of rubber and plastic properties, combining the elasticity of rubber and the processability of plastic. The housing 1 and the waterproof structure 3 are formed by two-color injection molding, ensuring both the overall rigidity of the housing and the waterproofness of the Type-C interface 9, achieving a tight fit between the entire waterproof mechanism 3 and the housing 1. The bottom of the housing 1 is bolted to the gas valve 2. The rotating shaft 12 on the gas valve 2 passes through the second through hole 11 on the top of the housing 1. A handwheel 13 is installed at the end of the rotating shaft 12. The circular plate 16 at the bottom of the waterproof cover 4 is aligned with the circular rotating structure 14 on the outside of the handwheel 13. The protrusion 17 on the circular plate 16 and the rotating groove 15 on the rotating structure 14 are aligned and tightened. An anti-foolproof structure 18 is provided on the outside of the rotating structure 14. A baffle 19 is set at the notch of the circular plate 16 corresponding to the anti-foolproof structure 18 for installing the anti-foolproof structure 18 of the waterproof cover 4.
