Abstract
The utility model discloses a welding neck flange with clamping grooves. The welding neck flange with the clamping grooves comprises a flange plate and a neck tube on the flange plate and is of a symmetrical integrated structure, the flange plate and the neck tube of a cylindrical structure shares an inner hole, fillets are arranged at the joint of the neck tube and the flange plate, eight mounting holes for bolt fixing are formed in the flange plate in a uniform distribution mode, the two concave clamping grooves are formed in an opening position of the neck tube on a symmetrical straight line, formed in a hole-hole symmetry mode, of the eight mounting holes for bolt fixing, and a concave groove is circumferentially formed in the lower end of the inner hole. The welding neck flange with the clamping grooves has the advantages of simple structure, reasonable design, high internal strength and durability, long service life, good use effect and capability of enabling fixing to be more stably and firmly by the aid of the clamping grooves and the concave groove.
