The valve spring is a small tool that ensures that the valve is seated in time and fits tightly to prevent the valve from jumping when the engine vibrates and destroying its sealing performance. The function of the valve spring ensures that the valve is seated in time and fits tightly to prevent the valve from jumping when the engine vibrates, thereby destroying its sealing performance. The pre-compression force generated by pre-compression during installation is used to overcome the inertia force of the valve and its transmission member during the valve closing process, and eliminate the gap generated by the inertia force between the transmission members to realize its function.
1. Check the free length of the valve spring. Use the caliper side to measure the free length of the valve spring, the value should meet the standard value. If it does not meet, it should be replaced.
2. Check the verticality of the valve spring. Check the verticality of the valve spring with a square and a flat plate. The value should be in accordance with the standard value, otherwise it must be replaced.
3. Check the preload of the valve spring. Use a load cell to detect the preload of the valve spring, the value of which should meet the standard. If the preload is lower than the standard value, the valve spring should be replaced.
4. In order to prevent damage, it should be compressed the spring regularly.
