Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of flush type one-way valve structures, including valve body 6, valve seat 1, spool 2 and spring base 3, institute
The center for stating 6 top of valve body offers the female mounting hole 1 of tool, and the lower central of valve body 6 offers connection mounting hole
One 7 centre bore 8；
The inside of the valve seat 1 be disposed with from top to bottom be interconnected and internal diameter be sequentially reduced mounting hole 2 14,
Valve chamber 10 and through-hole 1；The valve chamber 10 is connected to by mounting hole 2 14 with mounting hole 1, and passes through through-hole 1 and center
Hole 8 is connected to；The cross section of the mounting hole 2 14 is regular polygon, for the ease of carrying out dismounting operation by Allen wrench,
The cross section of the mounting hole 2 14 is preferably regular hexagon；
There is the matched external screw thread of internal thread with mounting hole 1, valve seat 1 to be matched by screw thread for the outside of the valve seat 1
Close the inside for being installed on mounting hole 1；The bottom of valve seat 1 and the bottom of mounting hole 1 abut against, and the bottom of valve seat 1 and peace
The bottom for filling hole 1 is planar structure；It is opened in the annular groove 9 of 1 bottom of valve seat and is equipped with and one 7 bottom surface phase of mounting hole
The sealing ring 5 of cooperation, in this way, 1 bottom plane of valve seat can cooperate with one 7 bottom plane of mounting hole with good sealing
Performance, will not be by between one 7 bottom of 1 bottom of valve seat and mounting hole from fluid that centre bore 8 enters to can guarantee
Clearance leakage.The sealing ring 5 is ED sealing rings can bear higher pressure, and can make valve due to using ED sealing rings
Whole structure is more readily processed, even if the bottom machining accuracy of the bottom of valve body 6 and mounting hole 1 can guarantee list if not high
Reliable sealing to valve bottom.
The spring base 3 is installed on the upper end of valve chamber 10 by screw-thread fit, and there are for spool 3 at the center of spring base 3
The through-hole 2 13 that top slides through, spring base 3 are provided through multiple overcurrents of its thickness direction around through-hole 2 13
Hole 15；Fluid is by flowing to the outside of valve body 6 when flowing hole 15 is opened for check valve in valve chamber 10, as a preferred embodiment, described
The quantity of flowing hole 15 is eight, and is uniformly distributed in around through-hole 2 13.
The spool 2 is arranged at the center of valve chamber 10, and the lower end of spool 2 has and matched with one 11 upper end of through-hole to beat
The boss 12 of through-hole 1 is closed on or off.The upper surface of the boss 12 is preferably annular plane structure.Under the boss 12
Portion is spherical structure, in this way, even if the machining accuracy of the valve chamber 10 and through-hole 1 inside valve seat 1 is not high, by spherical surface come with
The upper end of through-hole 1 matches the sealing performance that also can guarantee check valve.The top sliding of spool 2 is arranged in through-hole 2 13,
In this way, spool 2 can do the movement in axial direction always during being turned on and off through hole 1, it will not be relative to through-hole one
11, centre bore 8 generates radial deflection.
There is spring 4 to be set in the outside of spool 2 between boss 12 and spring base 3.
The course of work：When hydraulic oil is entered by centre bore 8 and is discharged by one 7 upper end of mounting hole,
The hydraulic oil entered in centre bore 8 by lower part acts on the lower surface of boss 12 by pressure, when pressure reaches energy
When overcoming 4 pressure value of spring, spool 2 is pushed to top, and during being somebody's turn to do, the top of spool 2 is slided in through-hole 2 13, to
Spool 2 only does the movement in axial direction, and when the lower surface of boss 12 is detached with the upper end of through-hole 1, check valve is opened, in
The hydraulic oil liquid that heart hole 8 comes flows to the outside on 6 top of valve body by eight flowing holes 15 above spring base 3.Work as hydraulic oil
When flowing to the lower part of centre bore 8 in advance by one 7 top of mounting hole, hydraulic oil is acted on by eight flowing holes 15 above spring base 3
In the upper surface of boss 12, under the action of hydraulic coupling, the spherical surface of 12 lower part of boss is only bonded with the upper end of through-hole 1, institute
Can effectively prevent the reverse circulated of hydraulic oil.
