The principle of torque wrench clicking sound

So far there are still many users don't understand what is torque wrench make clicking sounds, today small make up to you by the instrument under the principle of torque wrench clicking sound. Actually very simple, mainly divided into the following steps to understand: 1, the torque wrench in a 'click' sound of prompting has reached after you claim on the torque value; 2, 'clicking' issued by a torque wrench is produced by itself within the torque release structure, its structure is divided into pressure spring, release the joint torque, torque rod three structure of 3, first on the torque wrench set the required torque value ( By the spring set on the plunger pressure to release the joint torque) , locking torque wrench, began to tighten the bolt. When the bolt torque values ( When using a torque greater than the pressure of the spring) After, can produce effect disconnect to the moment. At the moment have a disconnect effect issued a joint percussion, wrench 'clicking' issued by a metal case. Thus to confirm the torque values reminder ( Actually as we arm joints bend into 15 degrees in iron pipe may encounter moment 'straight after the principle of steel tube) 。 Listen to the above steps to explain if I understand, if you don't understand, you are welcome to inquire. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = phone: + 86 - 595 - Fax: 22515230-0769 23394660 QQ: 63765035: postal address: 523808 songshan lake high-tech industrial development zone of science and technology of nine road no. 1
