Description
Technical field:
The utility model relates to a kind of hydraulic control one-way valve, refers in particular to a kind of big flow hydraulic control one-way valve that is used for the coal mine fully-mechanized mining working hydraulic support.
Background technology:
In the prior art, the structure of big flow hydraulic control one-way valve is varied.The hydraulic control one-way valve that is used for the coal mine fully-mechanized mining working hydraulic support at present, form by valve body, plinth, spring, valve cone, valve seat, push rod, end cap etc., external surface has inlet and liquid outlet and hydraulic control mouth, because being polyformaldehyde sealing or coal, sealing means grinds the pad rubber seal, so the life-span of valve is shorter, is generally 5,000 times.Hydraulic control one-way valve is the key that can coal mine fully-mechanized mining working hydraulic support column cavity of resorption locking, and sealing performance must be reliable.
The utility model content:
The purpose of this utility model is to provide a kind of big flow hydraulic control one-way valve, its sealing performance is reliable, life test (surpasses 6 times of GB settings) more than 30,000 times, and metered flow is 400L/min, can realize the locking of coal mine fully-mechanized mining working hydraulic support column cavity of resorption.
For achieving the above object, the solution that the utility model is taked is: a kind of big flow hydraulic control one-way valve, it comprises valve body, plinth, spring, valve cone, valve pocket, valve seat, big spring, big push rod, push rod, end cap, has working chamber in the valve body, valve outer surface has inlet and liquid outlet and hydraulic control mouth, plinth is to reserve the safety valve installation site, valve cone and valve base sealing are rigid seal, liquid outlet is opened the front at valve body, the liquid pass hole of valve pocket and valve seat is an inclined hole, valve body inner port and big push rod contact surface setting-in O-ring seals and polyurethane rectangular seal.
The utility model has adopted the mode of valve cone and valve seat rigid seal, has prolonged the application life of valve.When the needs setting prop, liquid flows from the inlet feed liquor, the liquid outlet fluid; Behind the hydraulic control mouth feed liquor, the stressed valve cone that backs down of push rod, liquid flows from the inlet feed liquor, and the liquid outlet fluid realizes two-way circulating.Because the liquid outlet of valve is in the front of valve body, the inner components valve pocket of valve and the liquid pass hole of valve seat adopt the inclined hole setting, reduce damping, augmented flow, and metered flow can reach 400L/min.Valve body inner port and big push rod contact surface adopt O-ring seals and the compound seal of polyurethane rectangular seal, and sealing performance is reliable, and the life-span is long.The valve bulk life time is tested more than 30,000 times and (is surpassed 6 times of GB settings), can realize the locking of coal mine fully-mechanized mining working hydraulic support column cavity of resorption.

Fig. 1 is the fragmentary cross-sectional view of overlooking of present embodiment.
Fig. 2 is main pseudosection.
Among the figure: 1, valve body, 2, plinth, 3, spring, 4, valve cone, 5, valve pocket, 6, valve seat, 7, big spring, 8, big push rod, 9, push rod, 10, end cap, 11, O-ring seals, 12, back-up ring, 13, O-ring seals, 14, O-ring seals, 15, the polyurethane rectangular seal, 16, O-ring seals, 17, back-up ring, 18, O-ring seals, A, liquid outlet, K, hydraulic control mouth, P, inlet.
The specific embodiment:
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of big flow hydraulic control one-way valve, it comprises valve body 1, plinth 2, spring 3, valve cone 4, valve pocket 5, valve seat 6, big spring 7, big push rod 8, push rod 9, end cap 10, has working chamber in the valve body 1, valve body 1 external surface has inlet P and liquid outlet A and hydraulic control mouth K, plinth 2 is to reserve the safety valve installation site, valve cone 4 is sealed into rigid seal with valve seat 6, liquid outlet A opens the front at valve body 1, the liquid pass hole of valve pocket 5 and valve seat 6 is an inclined hole, valve body 1 inner port and big push rod 8 contact surface setting-in O-ring seals 14 and polyurethane rectangular seals 15.Valve cone 4 and valve seat 6 rigid seals, its material is 3Cr13.
Present embodiment is the big flow hydraulic control one-way valve of FDYA400/50 type, rated pressure: 50MPa, metered flow: 400L/min, working media: the mixed liquor of 5% oil emulsion and 95% neutral water.
