[0002] Gas is a general term for gaseous fuels. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas and coal gas. Gas pipeline joints are essential connectors in the process of laying gas pipelines. They are used to seal and connect two gas pipelines. If the sealing of the gas pipeline joints is not good, gas leakage may cause major safety accidents.

DETAILED DESCRIPTION

[0023] See also Figure 1-4 , a gas engineering pipeline connection sealing joint, comprising a joint body 1, wherein a connecting mechanism 2 is arranged inside the joint body 1;

[0024] The connecting mechanism 2 includes four bidirectional threaded rods 201, the right end of each bidirectional threaded rod 201 is rotatably connected to the inner wall of the joint body 1, the left end of each bidirectional threaded rod 201 is fixedly installed with a first bevel gear 202, and the inner wall of the joint body 1 is rotatably connected to two rotating rods 205, and the bottom end of each rotating rod 205 is fixedly installed with a bearing 3, and the bottom surface of each bearing 3 is fixedly connected to the inner bottom wall of the joint body 1. The rotating rod 205 can be supported by the bearing 3, thereby preventing the rotating rod 205 from deviating during rotation, thereby increasing the stability of the rotating rod 205.

[0025] Two second bevel gears 206 are fixedly installed on the outer surface of each rotating rod 205, and the outer surface of each first bevel gear 202 is meshed with the outer surface of the second bevel gear 206. The outer surface of each bidirectional threaded rod 201 is threadedly connected to two movable blocks 203. A handle 4 is fixedly installed on the top of each rotating rod 205, and each handle 4 has anti-skid grooves 5 arranged at equal distances on the outer surface. The handle 4 can facilitate people to rotate the rotating rod 205. The anti-skid grooves 5 can increase the friction between the rotating rod 205 and the handle 4, thereby increasing the convenience of rotating the rotating rod 205.

[0026] The outer surface of each movable block 203 is slidably connected to the inner wall of the joint body 1, and an arc-shaped clamping plate 204 is fixedly installed on the side where each group of movable blocks 203 are close to each other. An air inlet pipe 208 and an exhaust pipe 207 are arranged inside the joint body 1. Two limit blocks 6 are fixedly installed on the inner bottom wall and the inner top wall of the joint body 1. The inner wall of each limit block 6 is rotatably connected to the outer surface of the bidirectional threaded rod 201. The bidirectional threaded rod 201 can be limited by the limit block 6, thereby preventing the bidirectional threaded rod 201 from deflecting, thereby increasing the stability of the bidirectional threaded rod 201.

[0027] A contact frame 209 is fixedly installed on one end of the intake pipe 208 close to the exhaust pipe 207, and a contact plate 210 is fixedly installed on one end of the exhaust pipe 207 close to the intake pipe 208. The front of the contact frame 209 contacts the back of the contact plate 210, the front of the contact plate 210 contacts the back of two of the arc-shaped clamping plates 204, and the back of the contact frame 209 contacts the front of the other two arc-shaped clamping plates 204. A rubber pad 7 is fixedly installed on the outer surface of each arc-shaped clamping plate 204, wherein the outer surfaces of two rubber pads 7 contact the outer surface of the intake pipe 208, and the outer surfaces of the other two rubber pads 7 contact the outer surface of the exhaust pipe 207. The rubber pad 7 can increase the contact area between the arc-shaped clamping plate 204 and the intake pipe 208 and the exhaust pipe 207, thereby preventing the intake pipe 208 and the exhaust pipe 207 from shaking and increasing the installation stability of the intake pipe 208 and the exhaust pipe 207.

[0028] A connecting ring 8 is fixedly installed on the back of the contact disc 210, and the outer surface of the connecting ring 8 is slidably connected to the inner wall of the contact frame 209. The connecting ring 8 can be inserted into the contact frame 209, thereby increasing the friction between the contact disc 210 and the contact frame 209, and improving the sealing between the intake pipe 208 and the exhaust pipe 207.

[0029] A rubber ring 9 is provided on the back of the connecting ring 8, the front of the rubber ring 9 contacts the back of the connecting ring 8, and the back of the rubber ring 9 contacts the inner wall of the contact frame 209. The rubber ring 9 can seal the gap between the connecting ring 8 and the contact frame 209, thereby preventing the gas from leaking from the gap, and further increasing the sealing between the intake pipe 208 and the exhaust pipe 207.

[0030] The working principle of the utility model is as follows: when in use, firstly, the air inlet pipe 208 and the exhaust pipe 207 are inserted into the joint body 1, so that the contact frame 209 and the contact disk 210 are docked, and the connecting ring 8 can be inserted into the contact frame 209, and the handle 4 is manually held to drive the rotating rod 205 to rotate, so that the rotating rod 205 can drive the second bevel gear 206 to rotate, and the second bevel gear 206 can drive the first bevel gear 202 to rotate, so that the first bevel gear 202 can drive the bidirectional threaded rod 201 to rotate, thereby driving the movable blocks 203 to approach each other, so that the arc clamping plate 204 can clamp and limit the air inlet pipe 208 and the exhaust pipe 207, and the arc clamping plate 204 can block the contact frame 209 and the contact disk 210. The rubber pad 7 can increase the contact area between the arc clamping plate 204 and the intake pipe 208 and the exhaust pipe 207, so that the intake pipe 208 and the exhaust pipe 207 are installed more tightly, and the gap between the connecting ring 8 and the contact frame 209 can be sealed by the rubber ring 9, so as to prevent the gas from leaking out of the gap. The arc clamping plate 204 can be driven to separate from each other by rotating the two-way threaded rod 201 in the opposite direction, so as to release the limit on the intake pipe 208 and the exhaust pipe 207, so that the joint body 1 and the intake pipe 208 and the exhaust pipe 207 can be quickly connected or disassembled, which reduces the complexity of the operation of the staff during installation, connection or disassembly, and increases the connection or disassembly efficiency, making the gas engineering pipeline connection sealing joint more practical.
