When oil flows into from hydraulic fluid port one, when hydraulic fluid port two flows out, under the effect of oil pressure, promote piston to left movement, piston is made to be resisted against on ring-shaped step, now oil channel, axial bore, radial hole, side opening are communicated with oil-through hole, and oil enters in hydraulic fluid port two successively from hydraulic fluid port one after oil channel, axial bore, radial hole, side opening and oil-through hole.When oil flows into from hydraulic fluid port two, when hydraulic fluid port one flows out, under the effect of oil pressure, promote piston to left movement, make piston depart from ring-shaped step, spring is in compressive state, and now oil channel is communicated with flowing hole by throttle orifice, realizes throttling.
In above-mentioned one-way throttle pipe joint, the diameter of described throttle orifice is 0.8mm-1.5mm.
In above-mentioned one-way throttle pipe joint, be provided with fixing frame one in described hydraulic fluid port one, one end of above-mentioned spring acts on this fixing frame one, and its other end acts on piston.
In above-mentioned one-way throttle pipe joint, described fixing frame one is provided with the filter screen one for oil strain.
In above-mentioned one-way throttle pipe joint, in described hydraulic fluid port two, be provided with fixing frame two.
In above-mentioned one-way throttle pipe joint, described fixing frame two is provided with the filter screen two for oil strain.
Compared with prior art, this one-way throttle pipe joint has the following advantages:
Its reasonable in design, easy to process, filter screen one and filter screen two are set respectively in filler opening one and filler opening two, can be used for oil strain; Can effective guaranteed flow when oil enters into hydraulic fluid port two from hydraulic fluid port one, the object of throttling can be played when oil enters in hydraulic fluid port one from hydraulic fluid port two, thus effectively eliminate the phenomenon producing because system pressure is too high and acutely shake.
