Abstract
The utility model relates to a kind of Hydraulic Poppet Valve, comprise valve body, axial position along valve body offers valve body hole, in described valve body hole, poppet valve core is installed, described poppet valve core comprises conical section, cylindrical section, arc section, described conical section is between cylindrical section and arc section, valve seat in described conical section and valve body forms linear sealing, groove is offered along conical section surface hoop, the diameter of described arc section is identical with the biggest place diameter of conical section, and described cylindrical section, conical section, arc section are one-body molded, and through Quenching Treatment.By having additional cylindrical section on poppet valve core, play leading role, can prevent poppet valve core generation radial direction from rocking, by arc section is arranged in the front end of poppet valve core, can liquid flow impact be reduced, play the effect of buffering, fluted by starting in conical section, impurity remaining in liquid stream can be stored, prevent it from producing spool face and scratch.
Description
Technical field
The utility model relates to hydrovalve technical field, particularly relates to a kind of Hydraulic Poppet Valve.
Background technique
Hydrovalve is the Automation Elements of a kind of pressure oil operation, and it is by the control of voltage distribution valve pressure oil, and usual and electromagnetic distributing valve combinationally uses, and can be used for the break-make of distant control water power plant oil, gas, water piping system.Be usually used in the oil circuits such as clamping, control, lubrication.Hydrovalve is the control unit in hydraulic system, and its function is the flow direction of liquid in hydraulic control system, pressure and flow, with make the operation mechanism of hydraulic actuator and driving thereof obtain required for moving direction, movement velocity and thrust etc.
The spool of hydraulic efficiency slide valve is divided into barrel valve, cone valve and ball valve, poppet valve core is because its good seal performance, therefore be widely used, but there is a very large problem in poppet valve core: in use, easy generation radial direction is rocked, and when spool is slided in valve body hole, noise improves, when liquid stream flows through cone valve mouth simultaneously, easily cause liquid flow impact.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Hydraulic Poppet Valve, by having additional cylindrical section spool on poppet valve core, play leading role, can prevent poppet valve core generation radial direction from rocking, by arc-shaped is arranged in the front end of poppet valve core, can liquid flow impact be reduced, play the effect of buffering.
The utility model is achieved through the following technical solutions:
A kind of Hydraulic Poppet Valve, comprise valve body, axial position along valve body offers valve body hole, in described valve body hole, poppet valve core is installed, described poppet valve core comprises conical section, cylindrical section, arc section, described conical section is between cylindrical section and arc section, and the valve seat in described conical section and valve body forms linear sealing, offers groove along conical section surface hoop.
As optimal technical scheme of the present utility model, the diameter of described arc section is identical with the biggest place diameter of conical section, and described cylindrical section, conical section, arc section are one-body molded, and through Quenching Treatment.
As optimal technical scheme of the present utility model, the cylindrical section upper end of described poppet valve core is provided with spring rod, is provided with spring at spring rod outer surface.
As optimal technical scheme of the present utility model, the shaft axis of described poppet valve core and valve body hole is located on the same line.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by having additional cylindrical section on poppet valve core, playing leading role, can prevent poppet valve core generation radial direction from rocking, by arc section is arranged in the front end of poppet valve core, can liquid flow impact be reduced, play the effect of buffering, fluted by starting in conical section, impurity remaining in liquid stream can be stored, prevent it from producing spool face and scratch.
