Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a head convenient to weld comprises a head body 1, wherein the bottom of the head body 1 is provided with a ring-shaped shrinkage straight edge 2, the head body 1 and the shrinkage straight edge 2 are of an integrally formed structure, an annular frame 8 is arranged in an annular cavity of the shrinkage straight edge 2, the annular frame 8 is composed of a large ring 801 and a small ring 802, the large ring 801 and the small ring 802 are of the integrally formed structure, the large ring 801 is fixedly connected with the inner wall of the shrinkage straight edge 2, a plurality of limiting pins 4 penetrate through the shrinkage straight edge 2 and the annular frame 8, the limiting pins 4 are in sliding fit with the shrinkage straight edge 2 and the small ring 802, springs 9 and flanges 7 are arranged outside the limiting pins 4, the springs 9 are sleeved on the outer portions of the limiting pins 4, the flanges 7 are fixed on the inner wall of the limiting pins 4, and the limiting pins 4 are tightly attached to the inner wall of a pressure container.
Specifically, as shown in fig. 2, a rubber sleeve 3 is bonded to one side of the limit pin 4 close to the outer wall of the contraction straight edge 2, and the rubber sleeve 3 increases the friction force between the limit pin 4 and the inner wall of the pressure container, so that the seal head body 1 is more stably fixed.
