Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawings
And embodiment, the present invention is further elaborated.Should be appreciated that described herein specifically
Embodiment only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, in one embodiment of the invention, described motor-driven plug-in mounting flow is watched
Take valve and include valve body 1, poppet valve core 2, with the gland 3 of fluid reflux mouth O, control spool 4, electricity
Machine bearing 5, attachment means, i.e. slip coupling 6, motor 7, nut 8, spring 9.Valve body 1
On have fluid inlet P, fluid issuing B and corresponding duct, control to have step and be loaded on cone on spool 4
In the inner chamber of spool 2, poppet valve core 2 has the ducts such as duct P1 and O1, control the step of spool 4
Matching with the duct on poppet valve core 2, there is screw thread the one end controlling spool 4, this threaded one end
Engage with nut 8 through gland 3, and be connected with the outfan of motor 7 by slip coupling 6,
This threaded one end can rotate and axial linear movement in slip coupling 6.Spring 9
Being arranged on the top of poppet valve core 2, its one end is connected with gland 3, and gland 3 seals with valve body 1 and is connected,
Motor support base 5 is arranged on gland 3, and motor 7 is arranged on motor support base 5.
The lumen segmentation of poppet valve core 2 is become epicoele and cavity of resorption by the step controlling spool 4.At inoperative shape
Under state, duct P1 and duct O1 be co-located in control spool 4 step in, fluid from P mouth through hole
Road P1 guides to, in the step of control spool 4, then flow in the O1 of duct, and through duct, O1 guides to gland
3, and flow out from fluid reflux mouth O, now, fluid flows into from P mouth, through duct P1, control valve
Core 4, duct O1, finally flow out from O mouth, define a complete fluid passage.In work
Under state, motor 7 rotates, and is rotated by slip coupling 6 band brake control valve core 4, simultaneously because
The effect of nut 8, controls spool 4 and produces axial linear movement.When controlling spool 4 at axis direction
When upwards producing displacement, duct P1 is introduced poppet valve core 2 cavity of resorption, by hole by the step controlling spool 4
Road O1 introduces poppet valve core 2 epicoele, and aforesaid fluid path is destroyed, and poppet valve core 2 stress balance is broken
Bad, poppet valve core 2 moves, until restoring balance, now, poppet valve core 2 completes control valve
The tracking of core 4, i.e. P mouth and the tracking to motor corner of the B mouth aperture.Control spool 4 in axis side
In time producing downwards displacement, in like manner.As long as accurately controlling rotating speed and the corner of motor, so that it may accurately control
P mouth processed and the aperture of B mouth and response time, thus it has been accurately controlled flow output, completed percentage
Control or SERVO CONTROL.
In the present embodiment, described motor can be various motor, including direct current, exchange, stepping,
The various motor such as servo.If employing motor, then this motor driving plug-in mounting serving volume valve is exactly
Digital plug-in mounting serving volume valve.
In the present embodiment, described control spool 4 can be three-way valve or cross valve.
In the present embodiment, the screw thread of described control spool 4 can be one start screw or multiple thread.
In the present embodiment, described attachment means is slip coupling, and it can also be to connect sliding sleeve,
Ensure that controlling the threaded one end of spool 4 rotates and the attachment means of axial linear movement
May be applicable to the present invention.
In the present embodiment, the fluid that this motor-driven plug-in mounting serving volume valve is suitable for is gas or liquid
Body.
In the present embodiment, described valve body 1 has at least two duct.
In the present embodiment, described nut 8 and gland 3 are two independent parts, it is also possible to will
The two is made of one.
Refer to Fig. 2, the present invention provides another kind of embodiment, the content of this embodiment and aforementioned enforcement
Example is essentially identical.Difference is: when valve body 1 is to lengthen valve body, can be by direct for motor 7
It is arranged on valve body 1, saves motor support base 5, provide cost savings.
Refer to Fig. 3, the present invention also provides for another kind of embodiment, the content of this embodiment and aforementioned reality
Execute example essentially identical.Difference is: when motor-driven plug-in mounting serving volume valve is small-sized plug-in mounting
Serving volume valve, when the power on poppet valve core 2 that acts on is little, this motor-driven plug-in mounting flow servo
In the way of valve directly can drive poppet valve core 2 to use motor 7.The most motor-driven plug-in mounting flow is watched
Taking valve and include valve body 1, poppet valve core 2, gland 3, motor support base 5, attachment means, i.e. slide shaft coupling
Device 6, motor 7, nut 8, spring 9.Fluid inlet P, fluid issuing B and phase is had on valve body 1
Answering duct, one end of poppet valve core 2 to have screw thread, this threaded one end is nibbled through gland 3 with nut 8
Closing, and be connected with the outfan of motor 7 by slip coupling 6, this threaded one end can slided
Rotate and axial linear movement in dynamic shaft coupling 6.Spring 9 is arranged on the top of poppet valve core 2,
Its one end is connected with gland 3, and gland 3 seals with valve body 1 and is connected, and motor support base 5 is arranged on gland
On 3, motor 7 is arranged on motor support base 5.
In a non-operative state, although poppet valve core 2 is by the pressure of fluid and the elastic force of spring 9, but
Due to the effect of the fastening force that nut applies, poppet valve core 2 is tightly pushed down P mouth, is not allowed fluid through P mouth
Flow out from B mouth.Under in working order, motor 7 rotates, and drives poppet valve core by slip coupling 6
2 rotate, simultaneously because the effect of nut 8, poppet valve core 2 produces axial linear movement, on axis
Producing displacement, now P mouth is opened, and fluid flows out from B mouth through P mouth.As long as accurately controlling motor
Rotating speed and corner, so that it may accurately control P mouth and the aperture of B mouth and response time, thus control accurately
Having made flow output, completed percentage controls or SERVO CONTROL, and plug-in mounting serving volume valve now is exactly pure
Electronic plug-in mounting serving volume valve.
In the present embodiment, motor-driven plug-in mounting serving volume valve employs spring 9 parts, its
Act primarily as the effect of Screw Thread Fit Clearance on nut and poppet valve core 2 that eliminates, but can not also be used this
Parts, reach cost-effective purpose.
The foregoing is only presently preferred embodiments of the present invention, be not used for limiting the enforcement model of the present invention
Enclose；If without departing from the spirit and scope of the present invention, the present invention is modified or equivalent,
All should contain in the middle of the protection domain of the claims in the present invention.
