Fig. 3 is the structural representation of the embodiment of the utility model one.
Fig. 4 is the exploded view of the embodiment of the utility model one.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.
Referring to Fig. 1-Fig. 4, this new motorized needle valve, including provided be sequentially communicated intake tunnel 11, regulation passage 12,
The valve body 1 of exhalant canal 13, valve body 1 is provided with needle 2 and moved back and forth for valve needle 2 adjusts the water of passage 12 to change
The motor 3 of flow, described one end of needle 2 are 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 corresponding 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 the pitch of matching thread axle 31, the high precision movement of needle 2 is realized, make the water-carrying capacity regulation of regulation passage 12 more accurate
Really.
Further, the intake tunnel 11, regulation passage 12, form 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 and installation of thread spindle 31 are easier to realize, while the assembly precision between aforementioned components is more convenient for ensureing, makes
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
It is sequentially connected and forms needle 2, 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
The screw channel 22 connect, the stress at connecting seat 23 is larger, therefore the radial dimension of connecting seat 23 is maximum in needle 2, ensures to connect
The intensity of joint chair 23, improve 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 assemble.
Further, the seal ring assembly includes the first sealing ring 42 and the second sealing ring 43 that are stacked, and first
The sealing ring 43 of sealing ring 42 and second has Teflon to be fabricated, and has the advantages of 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 catch 61, and catch 61 is corresponded on 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, when needle 2 is moved to maximum position to completely close regulation passage 12, catch 61 presses the first fine motion
Switch 62.
Referring to Fig. 2, when needle 2 is moved to minimum position to fully open regulation passage 12, 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 motor 3 from dallying to damage
Motorized needle valve.
Further, it is provided with the support 5 and limits the guide holder 51 for linear motion of needle 2, 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
Moved along a straight line along its axial direction, 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 preferred embodiment of the present utility model, rather than of the present utility model to limit with this
Claims, according to the equivalent variations made in scope of protection of the utility model, still belong to what the utility model was protected
