As further scheme of the invention：Dismountable bonnet is provided with the left of the accommodating chamber.
Compared with prior art, the beneficial effects of the invention are as follows：In use, hydraulic oil entered circulation from male connection
Road, and flowed out successively after damping hole, excessively ebb interval and accommodating chamber from internal thread interface.
Starting stages, 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, has the function that regulation damping；Male connection and internal thread interface are set, with fitting
The oil path block matched somebody with somebody coordinates the external of the damping unit that can realize hydraulic control hydraulic valve easily, is convenient for changing, reduce maintenance difficulties and
Cost.
Described in synthesis, this new structure advantages of simple, solves existing hydraulic control hydraulic valve internal damping by external mode
The shortcomings that being difficult to change, maintenance difficulties and cost are reduced, while can also simply and easily adjust damping, practicality is extremely strong.
