Throat clamp is a fastener used for connecting soft and hard pipes. There are many names in China, such as rubber hose clamp, pipe clamp, clamp, pipe clamp, etc. It is widely used in automobiles, tractors, forklifts, locomotives, ships, industrial machinery, petroleum, chemicals, pharmaceuticals, food, wine making, sewage treatment, purification and dust removal, ventilation systems, and is an ideal connecting fastener. According to the types, there are mainly American type throat hoop, German type throat hoop, single ear endless throat hoop, T-type throat hoop, R-type throat hoop, etc. The following is a brief introduction of the characteristics and functions of these types of throat hoop.
1. American type throat clamp, also known as conventional type throat clamp, is a widely used universal type throat clamp
Features: The rectangular hole slot on the steel strip provides a more powerful and accurate bite, and the torque is larger than that of the German throat hoop; The disadvantage is that there is a dead angle under the worm, which is easy to cause leakage
Applications: American type hose clamps are widely used, mainly in the automotive industry (air inlet system, radiator hose, heater hose connection, connection of pipe fittings such as turbocharger, diesel particulate filter, exhaust gas circulation system), fire protection, railway, white goods, agriculture, maritime, medical and food industries
2. The main difference between the German type hose clamp and the American type hose clamp is that it is non perforated. The non perforated and flanging design can protect the hose surface from damage
Features: balanced torque, uniform pressure, stable and safe fastening effect; The disadvantage is that there is a dead angle under the worm, which is easy to cause leakage
Application: It is usually used in the automobile industry, white goods, industry, mining, maritime and other industries, especially the connection of hoses. The corresponding materials can be selected according to the actual application environment
3. Single ear endless hose clamp
Features: 360 ° stepless design, the hose surface is compressed under uniform force, and it is sealed in all directions without dead angle; Cochlear design can compensate the size change of the fastener caused by temperature change, maintain a good fastening state for a long time, and effectively prevent leakage; Compact shape, simple installation, fast and safe.
Application: It is widely used in hose and plastic pipe, especially in beverage, automobile, ship, motorcycle, industry and other fields
Installation: The installation of this type of hose clamp requires the use of a special single ear electrode less pliers
Put the hose on a single ear stepless hose clamp of appropriate size, put it on the connecting device, place the hose clamp on the correct position, and then clamp the hose clamp with a single ear straight jaw pliers
When space is not allowed, side jaw pliers can be used to make them parallel to the pipe fittings during installation
4. T-type strong hose clamp
Features: The band has strong tension and large torque, and provides uniform sealing pressure. 360 ° free of dead angle can effectively prevent leakage. The band edge and inner side are rounded to protect the rubber hose. The welded structure improves safety and reliability
Application: T-type bolt hose clamp is used to provide leak free connection. Typical installation includes air inlet and hose of truck, automobile cooling valve pipe, turbine flange connection, motorcycle exhaust system, marine application, rubber hose of irrigation system, rubber hose and filter bag of water pump, etc
