[0019] As Figures 1 to 7As shown, a stainless steel heavy sealing nut, which comprises a nut body fastening column 1 projected as a regular hexagon in the up-down direction, the upper end center of the nut body fastening column 1 is provided with a cylindrical mounting combined fastening thread hole 2 penetrating the whole lower end, which is the main body fastening matching hole when the nut is fastened. The upper and lower end faces of the nut body fastening column 1 are respectively provided with a symmetrical and integrally formed conical reinforced sealing stabilizing column 3 at the center position, which can guarantee higher structural strength on both sides and provide sufficient matching space for the sealing performance of the matching position. The size of the outer side end face of the reinforced sealing stabilizing column 3 is larger than that of the side end face close to the nut body fastening column 1, and the upper and lower end faces of the nut body fastening column 1 and the reinforced sealing stabilizing column 3 form an external sealing matching groove with the cross section opening outward, which has the effect of preventing the nut from being separated when the sealing assembly is matched at this position, and the installation operation is more convenient. The center position of the reinforced sealing stabilizing column 3 is provided with a conical inner side sealing matching groove 4 communicated with the mounting combined fastening thread hole 2, which can tightly connect with the inner side sealing assembly and guarantee better sealing safety. The taper of the inner side sealing matching groove 4 is opposite to that of the reinforced sealing stabilizing column 3, which ensures that the inner and outer sides form a sealing matching space preventing separation. The projection of the mounting combined fastening thread hole 2 in the up-down direction is located in the area of the projection of the inner side sealing matching groove 4 in the up-down direction, which guarantees more convenient internal fastening connection matching operation and prevents interference with the matching structure during fastening and matching.
