Preferably, the inner diameter of the gas inlet 4 and the gas outlet 5 is equal to the outer diameter of a commercially available household gas pipeline, so that the gas inlet 4 and the gas outlet 5 can be connected with the existing gas pipeline.
Preferably, the stent 2 is disposed at the maximum diameter of the body 1 to leave the largest gas delivery path.
Preferably, the sealing body 6 is made of foam material, can float on the water surface and does not react with the fuel gas.
Preferably, the maximum diameter of the main body 1 is 1.5-2 times of the maximum diameter of the sealing body 6, so as to keep a larger gas delivery passage.
Preferably, the diameter of the sealing body 6 is larger than or equal to that of the air inlet 4, so as to ensure that the sealing body 6 can completely block the air inlet 4.
Preferably, the number of the connecting rods 3 is at least 2, so that the bracket 2 is more stably fixed on the main body 1.
Preferably, a guide rod is arranged at one end of the sealing body 6 close to the air outlet 5, and the sealing body 6 can just fall into the bracket 2 after water is discharged.
The utility model has the advantages that: insert gas pipeline with this water joint, under the normal condition, sealed ball 1 is placed in side chamber 2, does not influence the conveying transportation of gas, and when the pipeline connects the mistake, water gets into gas pipeline and reachs water joint, and sealed ball 1 removes to air inlet 4 end because the effect of buoyancy, seals air inlet 4, and water can not get into follow-up gas pipeline. The utility model has the advantages of simple structure does not influence the transport of gas, and prevents that the refluence is effectual, and low in manufacturing cost and use cost can use repeatedly many times, long service life, can use widely.

Detailed Description
The present invention will be described in detail with reference to the following examples, but the scope of the present invention is not limited to the examples.
The utility model provides a domestic gas pipeline water joint, water joint constitute by main part 1, support 2, connecting rod 3 and seal 6, main part 1 and seal 6 all be the two toper forms of concatenation, main part 1 empty, air inlet 4 and gas outlet 5 set up respectively at the both ends of main part 1, air inlet 4 and the inside screw thread that is provided with of gas outlet 5, be connected air inlet 4 and gas outlet 5 with gas pipeline respectively, the gas gets into from air inlet 4, exports from gas outlet 5, support 2 be the ring form, connect inside main part 1 through connecting rod 3, seal 6 place on support 2, the diameter of support 2 is less than or equal to the maximum diameter of seal 6 to prevent that seal 6 from dropping from support 2, seal 6 be prepared by the material that density is less than the density of water, seal 6 can float on the surface of water when meeting water, and further block the air inlet 4 to prevent water from entering the subsequent pipeline to cause larger damage. The inner diameters of the air inlet 4 and the air outlet 5 are equal to the outer diameter of a commercially available household gas pipeline, so that the air inlet 4 and the air outlet 5 can be connected with the existing gas pipeline. The stent 2 is arranged at the maximum diameter of the main body 1 to keep the maximum gas delivery passage. The sealing body 6 is made of foam materials, can float on the water surface and cannot react with fuel gas. The maximum diameter of the main body 1 is 1.5-2 times of the maximum diameter of the sealing body 6 so as to keep a larger gas delivery passage. The diameter of the sealing body 6 is larger than or equal to that of the air inlet 4, so that the sealing body 6 can completely block the air inlet 4.
