As further scheme of the invention：The accommodating chamber left side is provided with dismountable bonnet.
Compared with prior art, the beneficial effects of the invention are as follows：When using, hydraulic oil entered circulation from male connection
Road, and successively after damping hole, excessively ebb interval and accommodating chamber from internal thread interface outflow.
Starting stage, the damping hole alignment flow channels of spherical shell are guided, drive adjusting rod to move down by rotating regulation handle,
So that voussoir overcomes spring force to move down, and then extrude positioning core and support it to the right so that guiding spherical shell gradually part or
The damping hole of fixed spherical shell is fully closed, the effect of regulation damping is reached；Male connection and internal thread interface are set, it is and suitable
The oil path block matched somebody with somebody coordinates the external of the damping unit that can easily realize hydraulic control hydraulic valve, is convenient for changing, reduce maintenance difficulties and
Cost.
Comprehensive described, this new structure advantages of simple solves existing hydraulic control hydraulic valve internal damping by external mode
The shortcoming changed is difficult to, maintenance difficulties and cost is reduced, while damping can also be adjusted simply and easily, practicality is extremely strong.
