The invention provides a kind of application method of above-mentioned hydraulic impulse valve, motor is in outside dynamic Control backspin
Turn, the rotating disk being fixed on motor axle is also rotated with, at the same time, under the fixation of end cap and pin, with oil clot
Will not rotate.Therefore rotating disk and with being relatively rotated between oil clot, and there is periodic duty process, periodic process is common
Divide 4 stages：
（1）The oil-filled stage：When the groove C on rotating disk with A1, A2 mouthful on oil clot with having overlap, hydraulic fluid port A from valve body is to delaying
The oil circuit for rushing chamber D is connected, and now oil circuit order is as follows：Oil duct A5 on hydraulic fluid port A, valve body, with cup-shaped hole E, the hydraulic fluid port on oil clot
Groove C on A1 and A2, rotating disk, with the ring-shaped step D1 on oil clot, valve body oil duct D2, cushion chamber D, the liquid warp from hydraulic fluid port A
Cross that above-mentioned oil circuit is oil-filled to cushion chamber D, the pressure in cushion chamber D is persistently raised, until in cushion chamber D pressure with come from hydraulic fluid port A
Pressure it is equal, above-mentioned Oil feeding process stops；
In such scheme, the hydraulic oil from hydraulic fluid port A enters in cup-shaped hole E, is formed to the axial thrust with oil clot, makes with oil clot
Compressed with rotating disk, so as to not have draining with the contact surface between oil clot and rotating disk, and the pressure of hydraulic fluid port A is higher, with oil clot and turned
Thrust between disk is bigger, and sealing effectiveness is better；
（2）The oil-filled holding stage：When the groove C that rotating disk continues to be rotated up thereon Chong Die with A1, A2 mouthful matched somebody with somebody on oil clot,
When now C grooves are not also overlap with B1, B2 mouthful matched somebody with somebody on oil clot, between cushion chamber D and hydraulic fluid port A, cushion chamber D and hydraulic fluid port B completely
In dissengaged positions, the pressure of cushion chamber D keeps constant；
（3）Drain the oil the stage：When the groove C that rotating disk continues to be rotated up thereon has overlap with B1, B2 mouthful matched somebody with somebody on oil clot, from valve body
On hydraulic fluid port B to cushion chamber D oil circuit connect, now oil circuit is as follows：Oil duct D2 on cushion chamber D, valve body, with the ring on oil clot
Oil duct B5, hydraulic fluid port B on groove C, oilhole B1 and B2, radial hole B3, annular groove B4, valve body on shape step D1, rotating disk, due to slow
The pressure of the pressure higher than hydraulic fluid port B of chamber D is rushed, liquid flows to hydraulic fluid port B by above-mentioned oil circuit from cushion chamber D, in the D of simultaneous buffering chamber
Pressure continuous decrease, until the pressure of cushion chamber D is equal with the pressure of hydraulic fluid port B, the above-mentioned process of draining the oil terminates；
（4）Drain the oil the holding stage：When the groove C that rotating disk continues to be rotated up thereon Chong Die with B1, B2 mouthful matched somebody with somebody on oil clot, this
When time slot C is not also overlap with A1, A2 mouthful matched somebody with somebody on oil clot, cut-out shape is completely between cushion chamber D and hydraulic fluid port A, hydraulic fluid port B
State, the pressure in cushion chamber D keeps constant；
By the aforementioned four stage, the pulse digit valve invented completes to be conveyed from its hydraulic fluid port A to the liquid of its hydraulic fluid port B, and has
There are pulse characteristicses, the volume or quality of the liquid for being conveyed are relevant with the volume of the rotating speed of motor and cushion chamber D.
The hydraulic compression formula hydraulic impulse valve that the present invention is provided, by end cap and with spring is set between oil clot, by end
The thrust of lid is passed to oil clot, makes to be in close contact with rotating disk with oil clot；In the oil-filled stage, the hydraulic oil from hydraulic fluid port A enters
Enter in cup-shaped hole E, hydraulic oil makes tightly to be forced together with rotating disk with oil clot, so as to match somebody with somebody to the axial thrust formed with oil clot
Contact surface between oil clot and rotating disk does not have draining, and the pressure of hydraulic fluid port A is higher, is got over the thrust between oil clot and rotating disk
Greatly, sealing effectiveness is better.
Beneficial effects of the present invention：Using the present invention, can both be realized effectively on the premise of hydraulic impulse control is realized
Sealing, can adjust the frictional force between flow block and rotating disk again, and output power of motor is also reduced to a certain extent.
Present invention is mainly applied to need to realize carrying out fluid Pulse Width Control, or pulsed flow can reach control purpose
Occasion, such as the occasion that pressure, flow to hydraulic system, position are controlled.

Groove C on A1 and A2, rotating disk, with the ring-shaped step D1 on oil clot, valve body oil duct D2, cushion chamber D, the liquid warp from hydraulic fluid port A
Cross that above-mentioned oil circuit is oil-filled to cushion chamber D, the pressure in cushion chamber D is persistently raised, until in cushion chamber D pressure with come from hydraulic fluid port A
Pressure it is equal, above-mentioned Oil feeding process stops；
In such scheme, the hydraulic oil from hydraulic fluid port A enters in cup-shaped hole E, is formed to the axial thrust with oil clot, makes with oil clot
Compressed with rotating disk, so as to there is no draining with the contact surface between oil clot and rotating disk；
（2）The oil-filled holding stage：When the groove C that rotating disk continues to be rotated up thereon Chong Die with A1, A2 mouthful matched somebody with somebody on oil clot,
When now C grooves are not also overlap with B1, B2 mouthful matched somebody with somebody on oil clot, between cushion chamber D and hydraulic fluid port A, cushion chamber D and hydraulic fluid port B completely
In dissengaged positions, the pressure of cushion chamber D keeps constant；
（3）Drain the oil the stage：When the groove C that rotating disk continues to be rotated up thereon has overlap with B1, B2 mouthful matched somebody with somebody on oil clot, from valve body
On hydraulic fluid port B to cushion chamber D oil circuit connect, now oil circuit is as follows：Oil duct D2 on cushion chamber D, valve body, with the ring on oil clot
Oil duct B5, hydraulic fluid port B on groove C, oilhole B1 and B2, radial hole B3, annular groove B4, valve body on shape step D1, rotating disk, due to slow
The pressure of the pressure higher than hydraulic fluid port B of chamber D is rushed, liquid flows to hydraulic fluid port B by above-mentioned oil circuit from cushion chamber D, in the D of simultaneous buffering chamber
Pressure continuous decrease, until the pressure of cushion chamber D is equal with the pressure of hydraulic fluid port B, the above-mentioned process of draining the oil terminates；
（4）Drain the oil the holding stage：When the groove C that rotating disk continues to be rotated up thereon Chong Die with B1, B2 mouthful matched somebody with somebody on oil clot, this
When time slot C is not also overlap with A1, A2 mouthful matched somebody with somebody on oil clot, cut-out shape is completely between cushion chamber D and hydraulic fluid port A, hydraulic fluid port B
State, the pressure in cushion chamber D keeps constant；
By the aforementioned four stage, the pulse digit valve invented completes to be conveyed from its hydraulic fluid port A to the liquid of its hydraulic fluid port B, and has
There are pulse characteristicses, the volume or quality of the liquid for being conveyed are relevant with the volume of the rotating speed of motor and cushion chamber D.
