Stainless steel sealing tube joint

Abstract

The invention belongs to the technical field of pipeline joints, and particularly relates to a stainless steel sealing tube joint. The stainless steel sealing tube joint comprises a joint body and stainless steel tubes; threads are arranged on the outer wall of the stainless steel tube; the joint body is a rubber tube, the inner wall of the two ends of the joint body is provided with first threads, second threads are arranged in the middle of the inner wall of the joint body, the large diameter of the thread of the second threads is larger than that of the large diameter of the thread of the first threads, and the joint body can adapt to two stainless steel tubes with different diameters through the first threads and the second threads; clamping hoops are arranged on the outer wall of thejoint body in a sleeved mode; and the clamp hoops are fastened with the joint body and the stainless steel tubes which are matched together through bolt fasteners. According to the stainless steel sealing tube joint, the first threads and the second threads are arranged on the joint body, so that the tube joint can be connected with two stainless steel tubes with different diameters, and the use range is expanded; and meanwhile, the stainless steel tubes at the two ends of the tube joint can be tightly and firmly connected through the clamping hoops and supporting blocks which can be insertedinto each other, and the connection fastening performance is strong.

Description

technical field [0001] The invention belongs to the technical field of pipeline joints, in particular to a stainless steel sealed pipe joint. Background technique [0002] Stainless steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The basic alloying elements of stainless steel include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for the structure and performance of stainless steel. [0003] There are also technical solutions for stainless steel sealed pipe joints in the prior art. For example, a Chinese patent with application number 201721097209 discloses a stainless steel sealed pipe joint, including a joint body and a stainless steel pipe. The joint body includes a firs...
