Hydraulic press throttle classified as followshydraulic fittings jic

The throttle is the structure of the most simple single most widely used flow control valve up the quantitative pump oil throttle spee d control loop or system, often in conjunction with the relief valve. In accordance with the form of manipulation of the barrier, the throttle can be divided into manual adjustment, accompanied by the throttle valve, mechanical moving parts of the trip file or cam control type trip throttle; throttle valve and check valve combination into way flow control valves, one-way trip throttle composite valvestainless steel hydraulic fittings

 

Working principle

Open the valve body inlet and outlet spool the left to open the axial triangle trough throttle channel, spool always snapping in putting on the action of the spring. Fluid flows from the inlet channels and the left end of spoolhydraulic components

Triangular slot into the channel from the outlet, outflow, leading to the act uator or tank. Adjust the handle through the push rod to the spool for axial movement can change with the flow in the orifice cross-sectional nep achieve the regulation of traffic
