What should I do if the valve spring seat is broken?

With the development of society, people gradually move towards a well-off society, and every household has bought a car. After driving for a long time, you may encounter various problems, such as how to handle valve spring breakage? The following editor will tell you how to handle a broken valve spring seat.

The valve is one of the most important components in an engine. The valves are divided into intake and exhaust valves, with a appearance similar to a horn shape. The intake valve is made of intake manifold, fuel mixed heat resistant alloy steel, STELITE cobalt chromium tungsten alloy steel, and other materials. Valve springs are mostly made of medium carbon chromium vanadium steel wire or silicon chromium steel wire, providing sufficient stiffness and toughness for the spring to withstand frequent compression loads and maintain appropriate elasticity.

When the valve seat is twisted, the temperature of the valve sealing surface and the local pressure between the valve seats simultaneously increase. The sealing surface of the valve often has grooves, which can cause burns after being washed by high-temperature gas. When carbon deposits are severe on the valve sealing surface and valve seat, the heat transfer conditions deteriorate and are prone to deformation, leading to valve burns.

After the valve spring is broken, remove the broken spring and install the two broken sections in reverse to use. You can also find a piece of 1mm thick iron sheet and cut it into a circle 1mm larger than the spring diameter. Inside, cut a circular hole with a diameter 4mm smaller than the spring diameter. The outer edge is cut into 4mm long cracks every 6mm. Fold it every other section to form a double-sided spring seat groove, and then put the spring adjusting head into the iron groove for use. If the spring breaks into several knots, you can remove the intake and exhaust valve adjusting screws of the cylinder, keep the valve closed, and stop the cylinder from working.

The engine generates power by mixing air and oil into the engine cylinders, and then expels combustion exhaust gas. The mechanism responsible for the intake and exhaust of the four stroke engine is the valve.
