We have already introduced the main structure of the corrugated flexible metal hose, and the functions of each part are also different. Next, we will introduce the corrugated flexible metal hose in detail. Specific information about flexible metal hose connectors and their three categories.
Here is the content list:
l The role of the joint
l Threaded
l Flange type
l Quick installation
The function of the corrugated flexible metal hose connector is to first connect the mesh sleeve and the corrugated flexible metal hose as a whole. At the same time, the connector is the part that connects the flexible metal hose and the flexible metal hose or other pipe fittings and equipment. A flexible metal hose ensures that the medium works normally in the pipeline system. The material of flexible metal hose connector is usually the same as the material of flexible metal hose and mesh sleeve, mostly stainless steel. To reduce the production cost of flexible metal hoses, some flexible metal hoses with larger diameters can be made of carbon steel when transporting non-corrosive or non-corrosive media; for flexible metal hoses that work with corrosive media, the joints can be made of carbon steel. If corresponding measures are taken in the design to avoid contact between the flexible metal hose and the medium, it can also be made of carbon steel. The structure of flexible metal hose joints is roughly divided into three categories: screw type, flange type, and fast type.
For flexible metal hose joints with a diameter of less than 50 mm, flexible metal hoses are mostly threaded flexible metal hose joints under high working pressure. When the threads are tightened, the two flexible metal hose joints of The inner and outer taper surfaces are closely matched to achieve sealing. The structure has good airtightness, but the concentricity of the two mating parts must be ensured when installing the flexible metal hose connector. To solve the problems of repeated disassembly, assembly, and difficulty in concentricity that are often seen in practical engineering, the flexible metal hose joint can also be designed to match the cone and the ball head.
Flexible metal hose joints with a diameter of 25 mm or more are mainly flange-type flexible metal hose joints under normal working pressure, which are sealed in the form of tongue and groove fit. The flexible metal hose joint can be rotated in the radial direction, and the flexible metal hose loop flange, which can also be slid in the axial direction, connects the two bodies under the action of the tension of the fastening bolt. The structure has good sealing performance, but the flexible metal hose joint is difficult to process, and the sealing surface of the flexible metal hose joint is easily scratched. On special occasions where quick release is required, the holes through which the flexible metal hose fastening bolts pass can be cut to make a quick release flange.
Various flexible metal hose joints with a diameter of less than 100 mm generally adopt a fast type under the conditions of flexible metal hose that requires quick installation and unloading. It is usually sealed with an "O"-shaped sealing ring made of fluoroplastic or special rubber. When the handle is moved at a certain angle, the flexible metal hose, which is equivalent to the multi-threaded claw finger, is locked; the tighter the "O"-shaped sealing ring is pressed, the better the sealing performance. The flexible metal hose structure is most suitable for fire scenes, battlefields, and other occasions where quick loading and unloading are necessary. In a few seconds, the flexible metal hose can be connected or disconnected without any special tools.
