Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figures 1 to 3, a kind of emulsion system feather valve, comprise valve body 1, described valve body 1 profile is cuboid, neutral position, side, described valve body 1 side has horizontal oil inlet hole 2, opposite side connects pilot valve 5, described oil inlet hole 2 connects emulsified liquid source, be positioned in described valve body 1 on oil inlet hole 2, lower both sides are respectively equipped with mounting hole and the delivery outlet of one-way valve 3 and relief valve 4, the spool of described one-way valve 3 and relief valve 4 is arranged in mounting hole, described oil inlet hole 2 is communicated with the inlet opening of one-way valve 3 and relief valve 4, the delivery outlet of described one-way valve 3 connects into emulsion system, the delivery outlet of described relief valve 4 connects emulsified liquid liquid tank, some tubules 6 are provided with by boring in described valve body 1, described oil inlet hole 2 is connected with the inlet opening of pilot valve 5 by tubule 6, the delivery outlet of described one-way valve 3 is communicated with the control end of pilot valve 5 by tubule 6, the output terminal of described pilot valve 5 is communicated with the delivery outlet of relief valve 4 by tubule 6.
The delivery outlet of described one-way valve 3 connects a threeway, and connects accumulator by threeway.
The mounting hole of described one-way valve 3 and relief valve 4 is furnished with stifled spiral shell 7 and seals.
Described valve body 1 is provided with two one-way valves 3 and two one-way valves 3 are parallel connection.
Described valve body 1 is provided with two relief valves 4 and two relief valves 4 are parallel connection.
In actual use, emulsified liquid enters from oil inlet hole 2, its pressure in oil inlet hole 2 is controlled by relief valve 4, and hydraulic oil enters hydraulic system through one-way valve 3, then control pilot valve 5 when the pressure of one-way valve 3 outlet end is excessive to open, now, emulsified liquid is entered emulsified liquid liquid tank by tubule 6 through pilot valve 5 by oil inlet hole 2, pressure is reduced, when Pressure Drop is closed to one-way valve 3 during one-way valve 3 cracking pressure, now pilot valve 5 is also closed simultaneously, pressurizes again in oil inlet hole 2 place, opens one-way valve 3 to system feed flow.
Owing to being integrated in by each spool on a valve body, coupled condition is stablized, and reaction velocity is fast, can be good at stablizing system pressure.
