Description

Technical Field

[0001] This utility model is a corrosion-resistant gas-sealing tee connector, belonging to the field of pipe fittings. Background Technology

[0002] Corrosion-resistant gas-sealed tee fittings are pipe fittings used to connect three gas pipelines, effectively preventing gas leakage and possessing corrosion resistance. Polyvinylidene fluoride (PVDF) has strong creep resistance, fatigue resistance, and chemical resistance, and can adapt to highly corrosive gas environments for a long time. Polytetrafluoroethylene (PTFE) has extremely high chemical stability, a low coefficient of friction, and good sealing performance. Therefore, T-type tee fittings made of PTFE are common pipe fittings. To improve the stability of the pipeline connection, two columns are installed on the tee fitting, and bolts are installed on the carrier after passing through the columns, thereby restricting the position of the tee fitting. Currently, the columns are connected to the tee fitting in a fixed manner, and the distance between the two columns is fixed. The distance between the two columns cannot be adjusted according to the distance of the threaded holes on the carrier, resulting in poor adaptability. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a corrosion-resistant gas-sealed tee connector to solve the problems mentioned in the background technology. This utility model realizes the adjustment of the distance between the two cylinders according to the distance of the threaded holes on the carrier, thereby improving the adaptability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant gas-sealed tee connector, comprising a straight pipe, a branch pipe connected to the straight pipe being installed at the middle of the outer surface of the straight pipe, two cylindrical supports symmetrically arranged about the branch pipe for inserting bolts being provided on the side of the straight pipe near the branch pipe, lugs being installed at both ends of the cylindrical supports, a screw being provided between the two lugs at the same end of the two cylindrical supports, the screw being connected to the branch pipe through a connector, a through hole being provided on one side of the lug, the end of the screw passing through the through hole, and adjusting nuts being provided on both sides of the lug along the length of the screw, the adjusting nuts being threadedly connected to the screw.

[0005] Furthermore, the connector includes two semicircular rings, and the branch pipe is fitted with two semicircular rings. The two semicircular rings form a ring structure. Both ends of the semicircular rings are connected and fixed with lugs. The two lugs on one semicircular ring are respectively fitted with the two lugs on the other semicircular ring. A small hole is opened on one side of the lug. The screw passes through the small hole. Two positioning nuts are threaded on the screw. The two lugs that fit together are arranged between the corresponding two positioning nuts.

[0006] Furthermore, the lug and the semicircular ring are integrally formed, and the lug is arranged along the radial direction of the semicircular ring.

[0007] Furthermore, a threaded head is fixedly connected to one end of the screw, and the threaded head and the screw are integrally formed. A threaded blind hole is opened on the side of the screw away from the threaded head, and the threaded head on one screw is threadedly connected to the threaded blind hole on another screw.

[0008] Furthermore, two reinforcing ribs are fixedly connected to one end of the support near the column, and the reinforcing ribs are fixedly connected to the column.

[0009] Furthermore, both ends of the straight pipe are threaded with a first pressure cap for pressing the plastic air tube, and the end of the branch pipe away from the straight pipe is threaded with a second pressure cap for pressing the plastic air tube.

[0010] Furthermore, the outer surface of the column is machined with an arc-shaped surface, which is in contact with the surface of the straight pipe.

[0011] The beneficial effects of this utility model are:

[0012] 1. Place the ring structure formed by the two semicircular rings onto the branch pipe, then insert the screw into the channel formed by the two matching small holes, and then use the positioning nut to restrict the relative position of the screw and the lug, thereby restricting the two semicircular rings on the branch pipe, thus completing the assembly of the screw and the branch pipe.

[0013] 2. Adjust the distance between the two cylindrical tubes. At this time, the relative position of the lug and the screw changes. When the distance between the two cylindrical tubes meets the distance requirement of the two threaded holes on the carrier, use two adjusting nuts to restrict the relative position of the screw and the lug. At this time, the position of the cylindrical tubes is restricted, so that the distance between the two cylindrical tubes can be adjusted according to the distance of the threaded holes on the carrier, thereby improving adaptability.

[0014] 3. Select an appropriate number of screws based on the distance between the two cylinders, and screw the threaded head of one screw into the threaded blind hole of another screw, and so on, to complete the assembly of multiple screws, thus eliminating the need to manufacture long screws.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a corrosion-resistant gas sealing tee connector, including a straight pipe 1, and a branch pipe 9 connected to the straight pipe 1 at the middle position of the outer surface of the straight pipe 1. Both the straight pipe 1 and the branch pipe 9 are components made of polytetrafluoroethylene material, which facilitates installation in gas transmission pipelines with high corrosiveness. Both ends of the straight pipe 1 are threaded with a first pressure cap 12 for pressing the plastic gas tube, and the end of the branch pipe 9 away from the straight pipe 1 is threaded with a second pressure cap 13 for pressing the plastic gas tube.

[0024] See Figures 1-3 Two cylindrical tubes 2 are symmetrically arranged about the branch pipe 9 on the side of the straight pipe 1 for inserting bolts. The arc-shaped surface of the outer surface of the cylindrical tube 2 fits into the surface of the straight pipe 1. Both ends of the cylindrical tube 2 are equipped with lugs 5. Two reinforcing ribs 4 are connected and fixed to the end of the lugs 5 near the cylindrical tube 2, so that the reinforcing ribs 4 are connected and fixed to the cylindrical tube 2, thereby improving the mechanical strength of the connection between the lugs 5 and the cylindrical tube 2.

[0025] See Figures 1-5A screw 6 is provided between two lugs 5 at the same end of the two cylindrical tubes 2. Two semi-circular rings 8 are fitted on the branch pipe 9, forming a ring structure. Both ends of the semi-circular rings 8 are connected and fixed with lugs 11. The lugs 11 and the semi-circular rings 8 are integrally formed. The lugs 11 are arranged along the radial direction of the semi-circular rings 8. The two lugs 11 on one semi-circular ring 8 are respectively fitted with the two lugs 11 on the other semi-circular ring 8. A small hole 16 is opened on one side of the lug 11. The screw 6 passes through the small hole 16. Two positioning nuts 10 are threaded on the screw 6. The two lugs 11 that fit together are set between the corresponding two positioning nuts 10. The ring structure formed by the two semi-circular rings 8 is fitted on the branch pipe 9. Then, the screw 6 is inserted into the channel formed by the two matching small holes 16. Then, the positioning nuts 10 are used to restrict the relative position of the screw 6 and the lugs 11, thereby restricting the two semi-circular rings 8 on the branch pipe 9, thus completing the assembly of the screw 6 and the branch pipe 9.

[0026] See Figures 1-3 The support lug 5 has a through hole 14 on one side, through which the end of the screw 6 passes. The support lug 5 has adjusting nuts 7 on both sides along the length of the screw 6. The adjusting nuts 7 are threadedly connected to the screw 6 to adjust the distance between the two cylindrical tubes 2. At this time, the relative position of the support lug 5 and the screw 6 changes. When the distance between the two cylindrical tubes 2 meets the distance requirement of the two threaded holes on the carrier, the two adjusting nuts 7 are used to restrict the relative position of the screw 6 and the support lug 5. At this time, the position of the cylindrical tubes 2 is restricted, so that the distance between the two cylindrical tubes 2 can be adjusted according to the distance of the threaded holes on the carrier, thereby improving adaptability.

[0027] See Figure 1 , Figure 2 and Figure 4 One end of the screw 6 is connected and fixed with a threaded head 3. The threaded head 3 and the screw 6 are integrally formed. The screw 6 has a threaded blind hole 15 on the side away from the threaded head 3. According to the distance between the two cylinders 2, select an appropriate number of screws 6 so that the threaded head 3 on one screw 6 is screwed into the threaded blind hole 15 on another screw 6. In this way, the assembly of multiple screws 6 is completed, so that there is no need to make a long screw 6.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
