Brief description of the drawings
Fig. 1 is the full closing state of one embodiment of the invention.
Fig. 2 is the full open state of one embodiment of the invention.
Fig. 3 is the structural representation of one embodiment of the invention.
Fig. 4 is the exploded view of one embodiment of the invention.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Referring to Fig. 1-Fig. 4, this new motorized needle valve, including provided with the intake tunnel 11 being sequentially communicated, regulation passage 12,
The valve body 1 of exhalant canal 13, valve body 1 is provided with needle 2 and moves back and forth for valve needle 2 to change the regulation water of passage 12
The motor 3 of flow, described one end of needle 2 is provided with the tapered needle 21 being flexibly connected with the regulation water inlet of passage 12, and the other end is set
There is screw channel 22, the correspondence screw channel 22 of motor 3 is provided with thread spindle 31, and thread spindle 31 is flexibly connected with screw channel 22.
By changing the taper of tapered needle 21, the amplitude of accommodation of motorized needle valve water-carrying capacity can be changed, according to actual use
Situation is adapted to the tapered needle 21 of different tapers.
In the present embodiment, motor 3 is stepper motor, and the angle of rotation of thread spindle 31 can be accurately controlled using stepper motor
Degree, then matching thread axle 31 pitch, realize the high precision movement of needle 2, make regulation passage 12 water-carrying capacity adjust it is more accurate
Really.
Further, the intake tunnel 11, regulation passage 12, constitute U-shaped water route between exhalant canal 13, needle 2 from
The side of exhalant canal 13 is stretched into regulation passage 12.
Further, the regulation passage 12, needle 2, thread spindle 31 are coaxially disposed, the structure being coaxially disposed make valve body 1,
Needle 2, the processing of thread spindle 31 and realization is easily installed, while the assembly precision between aforementioned components is more convenient for ensureing, made
The water-carrying capacity regulation for adjusting passage 12 is more accurate.
Further, the needle 2 includes connecting seat 23, shank 24, the tapered needle 21, shank 24, connecting seat 23
Composition needle 2 is sequentially connected, screw channel 22 is arranged in connecting seat 23.
Connecting seat 23, shank 24, the radial dimension of tapered needle 21 are reduced successively, and connecting seat 23 is provided with to be connected with thread spindle 31
Stress at the screw channel 22 connect, connecting seat 23 is larger, therefore the radial dimension of connecting seat 23 is maximum in needle 2, it is ensured that even
The intensity of joint chair 23, improves the durability of needle 2.
Further, seal ring assembly and the nut 41 for lock sealing coil assembly are provided with the valve body 1, it is described
Needle 2 sequentially passes through nut 41 and seal ring assembly, it is ensured that the sealing that valve body 1 and needle 2 are assembled.
Further, the seal ring assembly includes the first sealing ring 42 and the second sealing ring 43 being stacked, first
The sealing ring 43 of sealing ring 42 and second has Teflon to be fabricated by, and has the advantages that wearability is strong, service life is long.
Further, the valve body 1 is provided with the support 5 for being used for fixing motor 3.
Further, the needle 2 is provided with correspondence catch 61 on catch 61, support 5 or valve body 1 and is provided with the first fine motion
The microswitch 63 of switch 62 and second.
Referring to Fig. 1, needle 2 is moved to maximum position to completely close during regulation passage 12, and catch 61 presses the first fine motion
Switch 62.
Referring to Fig. 2, needle 2 is moved to minimum position to fully open during regulation passage 12, and catch 61 presses the second fine motion
Switch 63.
Catch 61 once presses to the first microswitch 62 or the second microswitch 63, i.e. needle 2 and is moved into maximum
Position or minimum position, the electric signal pressed pass to motor 3, and motor 3 is stopped operating, and motor 3 can only be turned round with valve needle 2
Rollback, such a control mode ensures that needle 2 can not cross maximum position or minimum position, also prevents from motor 3 from dallying to damage
Motorized needle valve.
Further, guide holder 51 for linear motion provided with needle 2 is limited in the support 5, motorized needle valve was run
Cheng Zhonghui produces certain vibration, causes needle 2 to swing, and guide holder 51 can limit the swing of needle 2, and limiting needle 2 can only
Axially moved along a straight line along it, it is ensured that the resistance to overturning of motorized needle valve.
Compared to old technology, the Flow-rate adjustment of this motorized needle valve is more linear, its flow curve back segment (i.e. needle 2 with
Adjust passage 12 distance it is increasing) Flow-rate adjustment effect still more significantly, realize being precisely controlled for motorized needle valve flow.
Above disclosed is only the preferred embodiments of the present invention, rather than limits with this claim of present invention
Protection domain, according to the equivalent variations made in the scope of the present invention, still belongs to the scope that the present invention is protected.
