Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a gas hose joint sealer. Background Art

[0002] In recent years, with the popularization of gas, gas valves with gas hose joints have been widely used.

[0003] When the gas hose is not installed on the gas valve, once the user accidentally opens the valve, a large amount of gas will be discharged from the gas hose joint of the valve, which is extremely likely to cause a gas accident.

[0004] In the prior art, the gas hose joint of the valve is either exposed without any protection or uses a common rubber sleeve head that is extremely prone to aging and external force damage. Therefore, a gas hose joint sealer is needed now. Content of the Utility Model

[0005] The purpose of the utility model is to provide a gas hose joint sealer, which protects the gas hose joint of the valve by setting a rubber head sealer, avoiding the direct exposure of the gas hose joint of the valve to the outside, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a gas hose joint sealer, including a reducing union. A baffle is fixedly installed on the outer arc surface of the reducing union. The other end of the baffle is fixedly installed with a threaded pipe. A sealing nut is sleeved and installed at the position where the baffle fits the outside of the reducing union. A sealing ring is embedded and installed inside the sealing nut. A rubber inner ring is embedded and installed on the inner arc surface of the sealing ring.

[0007] A sealing plug is sleeved on the outside of the reducing union. One end of the sealing plug is installed with a connecting threaded rod, and the connecting threaded rod is threadedly connected with the sealing nut.

[0008] Preferably, a side groove is opened at the outer end of the threaded pipe. A hexagonal air hole is centrally penetrated through the side groove. A through hole is centrally penetrated through the baffle, and the through hole and the hexagonal air hole are communicated and installed.

[0009] Preferably, a group of circular holes with the same diameter as the baffle are penetrated through the side of the sealing nut that fits the baffle. A threaded groove larger than the diameter of the circular hole is opened on the other side of the sealing nut.

[0010] Preferably, the sealing ring is sleeved on the outside of the baffle, and the rubber inner ring fits the outer arc surface of the baffle. The sealing ring is located inside the sealing nut and abuts against one side of the circular hole.

[0011] Preferably, a storage and protection groove is provided inside the sealing plug and the connecting threaded rod. After the connecting threaded rod is threadedly installed with the sealing nut, the tapered adapter extends into the storage and protection groove.

[0012] Preferably, the end of the connecting threaded rod abuts against the other side of the sealing ring. The outer arc surface of the tapered adapter does not contact the inside of the storage and protection groove, and the end of the tapered adapter does not contact the bottom surface of the storage and protection groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The gas hose joint of the valve is threadedly connected with the threaded pipe joint, so that the end of the gas hose joint of the valve extends through the tapered adapter. The sealing nut sleeved on the outer arc surface of the tapered adapter can threadedly connect with the sealing plug to ensure the connection state between the sealing plug and the tapered adapter. At the same time, the sealing ring arranged during the installation of the sealing nut abuts against the sealing nut to limit the sealing nut. And during the process of threading and tightening the connecting threaded rod and the sealing nut, the connecting threaded rod rotates and abuts against the sealing ring to further squeeze the sealing ring to improve the sealing effect, thereby protecting the gas hose joint of the valve and preventing the gas hose joint of the valve from being directly exposed to the outside, which affects the service life of the gas hose joint of the valve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0023] As Figures 1 - 5 shown, the present utility model provides a gas hose joint closure, including a tapered joint 1. A baffle 2 is fixedly installed on the outer arc surface of the tapered joint 1. A threaded pipe 3 is fixedly installed at the other end of the baffle 2. A sealing nut 7 is sleeved at the position where the outer part of the tapered joint 1 fits the baffle 2. A sealing ring 10 is embedded in the sealing nut 7. A rubber inner ring 11 is embedded in the inner arc surface of the sealing ring 10. A sealing plug 12 is sleeved outside the tapered joint 1. A connecting threaded rod 13 is installed at one end of the sealing plug 12. The connecting threaded rod 13 is threadedly connected with the sealing nut 7.

[0024] A side groove 5 is opened at the outer end of the threaded pipe 3. A hexagonal air hole 6 is centrally penetrated through the side groove 5. A through hole 4 is centrally penetrated through the baffle 2. The through hole 4 and the hexagonal air hole 6 are connected and installed. The baffle 2 installed on the outer arc surface of the tapered joint 1 limits the sealing nut 7, and at the same time can also limit the gas hose joint of the valve to prevent the end of the gas hose joint of the valve from contacting the sealing nut 7, improving the protection of the gas hose joint of the valve. The threaded pipe 3 installed at the outer end of the baffle 2 enables the device to be stably connected to the gas hose joint of the valve, reducing the occurrence of gas leakage while ensuring the integrity of the device and the gas hose joint of the valve. The side groove 5 opened at the outer end of the threaded pipe 3 and the hexagonal air hole 6 opened at the center of the side groove 5 communicate with the through hole 4 opened at the center of the baffle 2, enabling the gas to pass through smoothly and be discharged.

[0025] A set of circular holes 9 with the same diameter as the baffle 2 are drilled through one side of the sealing nut 7 that fits the baffle 2. A threaded groove 8 larger than the diameter of the circular hole 9 is provided on the other side of the sealing nut 7. The circular holes 9 provided on one side of the sealing nut 7 ensure that the sealing nut 7 will not shake after being sleeved outside the baffle 2, and cooperate with the sealing ring 10 inserted inside the sealing nut 7 to reduce the gas leakage, greatly ensuring the safety of the device during use. The threaded groove 8 provided on the other side of the sealing nut 7 is used to connect with the connecting threaded rod 13 or connect with an external pipeline. When connecting with the connecting threaded rod 13, it can ensure that while the sealing plug 12 cooperates with the sealing nut 7 and the sealing ring 10 to protect the flare fitting 1, the situation of gas leakage is avoided.

[0026] The sealing ring 10 is sleeved outside the baffle 2, and the rubber inner ring 11 fits the outer arc surface of the baffle 2. The sealing ring 10 is located inside the sealing nut 7 and abuts against one side of the circular hole 9. The rubber inner ring 11 embedded inside the sealing ring 10 further improves the overall sealing performance of the device. The sealing ring 10 fits the inner wall of the threaded groove 8, while the rubber inner ring 11 fits the outer arc surface of the flare fitting 1, enabling the connecting threaded rod 13 to play a better role in preventing air leakage when threadedly connected with the sealing nut 7, greatly improving the safety of the device during use, and also ensuring the connectivity between the sealing plug 12 and the sealing nut 7, enhancing the protection of the flare fitting 1, and further enhancing the protection of the gas hose joint of the valve.

[0027] It should be noted that a storage protection groove 14 is provided inside the sealing plug 12 and the connecting threaded rod 13. After the connecting threaded rod 13 is threadedly installed with the sealing nut 7, the flare fitting 1 extends into the storage protection groove 14. The storage protection groove 14 provided on the sealing plug 12 and the connecting threaded rod 13 enables the flare fitting 1 to extend into the storage protection groove 14 when the connecting threaded rod 13 is threadedly connected with the sealing nut 7. The flare fitting 1 is protected by the sealing plug 12, avoiding damage to the flare fitting 1 during long-term use, and at the same time avoiding the situation of gas leakage caused by the exposure of the flare fitting 1 to the outside, greatly improving the safety of the device during use.

[0028] Specifically, the end of the connecting threaded rod 13 abuts against the other side of the sealing ring 10. The outer arc surface of the flare fitting 1 does not contact the inside of the storage protection groove 14, and the end of the flare fitting 1 does not contact the bottom surface of the storage protection groove 14. After the connecting threaded rod 13 in the sealing plug 12 rotates and abuts against one side of the sealing ring 10, it can protect the connecting threaded rod 13 and also improve the sealing performance of the device during use and the protection of the flare fitting 1. The flare fitting 1 does not contact the inner wall of the storage protection groove 14, avoiding compressive damage to the flare fitting 1 after the sealing plug 12 is threadedly connected with the sealing nut 7, so that the flare fitting 1 has sufficient space to be stored and protected.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
