For the public, the flange may be a relatively unfamiliar concept. In fact, the flange, also called flange or flange, is a part of the connecting pipe. It is connected to the end of the pipe, there are holes on the flange, and the bolts can pass through, so that the two flanges are tightly connected, and the flanges are sealed with gaskets. Flange connections are widely used in industrial pipelines. Due to the high requirements of the flange, the use of stainless steel production, so the cost is relatively high. Flange as a pipe connection device, has been widely used in all walks of life. However, in order to produce a high-strength flange, a large amount of raw materials and energy are often wasted in the prior art, which increases the production cost of the enterprise. At the same time, due to the wide range of applications of flanges, some fields require flanges to be resistant to both high temperature and low temperature, and the current flanges often cannot meet people's requirements. Flange is a kind of connector, generally used to connect the pipe end. Of course, there are also flanges at the equipment inlet and outlet for the connection between the two equipment. However, in the prior art, the flange has a single function.
In order to overcome the shortcomings of existing technology, technical personnel.A flange is provided to solve the problem that the function of the flange is relatively single.It uses the following technical solutions to achieve: the paragraphThe flange includes a fixed disc and a rotating disc, the fixed disc includes a first flange disc and a first sleeve, the rotating disc includes a second flange disc and a second sleeve, the first sleeve is sleeved on the outside of the second sleeve, the first sleeve and the second sleeve are coaxially rotatably connected, the side of the first sleeve is provided with a through hole, and the side of the second sleeve is provided with a limiting groove and a limiting hole, the limiting device is matched with the limiting slot and the limiting hole.
among them,The depth of the limit groove is less than the depth of the limit hole, and the limit groove is an arc-shaped groove. The number of the limiting slots is at least two, and the number of the limiting holes is at least two. The number of limit slots is greater than the number of limit holes. Limit slots between any two adjacent limit holes are evenly distributed. The at least two limiting holes are evenly distributed.this paragraphThe flange further includes two limit blocks, the two limit blocks are fixed on the side of the second sleeve, and all the limit slots and all the limit holes are located between the two limit blocks. The first flange is provided with a mounting hole. The second flange is provided with a mounting hole.
The new typeFlangehas the following advantages: The heat treatment process of the flange improves the hardness of the flange. The flange forging blank is covered with a mixture of water and plant ash, which can play a better heat preservation effect, reduce the defects of flange casting pores and slag holes, and improve The yield increases the low temperature resistance and high temperature resistance of the flange-50 - 60The normal use of the environment, so that the flange is more applicable.
