Between two fixed connecting rods in spring assembly is set, when spring cup pressing plate pushes valve spring cover, valve stem can smoothly enter
In the valve stem positioning cylinder valve stem positioning hole for entering spring assembly, when installing locking plate, two valve locking plates are first put into valve bullet
On the inside of spring lid；Valve disc is withstood with the strap of fixed chuck, the spring cup pressing plate of dismounting work department is pressed in valve spring cover
On, the flexible knob of adjustment so that valve spring cover is snapped down to valve stem middle and upper part adjusts flexible knob so that dismounting work again
Make portion integrally to move up, valve spring covers cunning under elastic force effect, two valve locking plates are as valve spring cover is together along along valve stem
Rise, by automatically into fixed position, that is, completing the installation of two valve locking plates during valve stem fixation bayonet socket, by increasing spring assembly,
Locking plate need not be adjusted repeatedly to enter fixed position when assembling locking plate and spring cup, substantially reduced valve installation time, carried
Rise engine valve assembling quality.
Inventive engine spiracle disassembling and assembling instrument is further described with reference to the accompanying drawings and examples.
