Preferably, the pipe clamp assembly comprises an arc-shaped support, a through hole is formed in one end of the arc-shaped support, and a plurality of clamping grooves are formed in the side wall, far away from the through hole, of the arc-shaped support.

Preferably, the protection pad is made of elastic rubber.

Preferably, the valve body is provided with a corrosion protection layer on the outside.

Preferably, the heat insulation cotton is not limited to the material of zirconium-containing ceramic fiber cotton.

Compared with the prior art, the beneficial effects of the utility model are that:

1. according to the pipeline safety welding valve, the protection pad is arranged to be matched with the protection sleeve, so that the welding seam between the welding valve and the pipeline can be protected, the welding seam between the welding valve and the pipeline is prevented from being corroded, the pipeline is prevented from being leaked and damaged, and the safety and the service life of the welding valve are improved;

2. this pipeline safety welding valve through setting up thermal-insulated cotton cooperation baffle, can avoid when welding the welding valve to the pipeline on, the high temperature that the welding produced causes the damage to the protection pad to thermal-insulated cotton can shrink under the drive of medium in the pipeline, reduces the thickness of protection pad, reduces the resistance of protection pad to medium in the pipeline.
