Description
Technical field
The utility model relates to a kind of flow regulator, is specifically related to a kind of flow regulator of numerical control electric gate.
Background technique
Self-operated flow control valve has flow set and regulates and keep constant flow two kinds of functions.And the realization of these two functions is completed by two-part component in valve.In flow set adjustment, mainly contain the valve of two kinds of structures in the market, one is pivoted housing formula switch-mode regulation structure, this structure relies on pivoted housing change its flow area in main valve body radial direction and change flow, certain interval must be had to be convenient to manually due to pivoted housing and valve body or use electric actuator to drive, the existence in this gap just makes leakage rate inevitably increase, therefore rotating sleeve is difficult to close completely.Another kind of structure is coning plug structure, and this structure can realize turning off but be exert pressure by screw rod due to it, and can only determine opening degree by number of turn-taking when controlling flow, flow indication is very indefinite.
After flow set is good, drive floating valve plug throttling, pressure regulation by pressure feedback by the effect of Regulation spring, diaphragm by second portion, keep constant flow constant.
Traditional self-operated flow control valve focuses on the performance ensureing that rate-of flow is constant, but cuts off rate-of flow completely under can not ensureing off state, thus does not have shutoff effect, and vent flow is still very large under many circumstances.In engineering, just must increase a shut-off valve like this, this will increase cost and installing space.
Model utility content
The utility model provides a kind of flow regulator of numerical control electric gate, to solve the malfunctioning technical problem of existing flow regulator Flow-rate adjustment.
In order to solve above technical problem, the technological scheme that the utility model is taked is:
A kind of flow regulator of numerical control electric gate, comprise safe screw mandrel, motor, train, safety bearing seat, safe screw, dynamic brake lining, quiet brake lining, position proximity switch, bolt and limit proximity switch, motor is connected to safe screw mandrel by train, safe screw mandrel is set with successively safety bearing seat and safe screw, train lower end is provided with screw mandrel, position proximity switch is provided with between train and safety bearing seat, dynamic brake lining is located at above safe screw mandrel, quiet brake lining is located at the safe screw mandrel left side, and limit proximity switch is located at below dynamic brake lining.
Preferably, the resolution of described position proximity switch is 0.5mm.
The utility model beneficial effect is embodied in: the moment of rotation one, decreasing adjust flux, because its frictional force smooth of plane machining is just very little, just to turn nested structure much little than traditional for moment of rotation, and this can save very large cost for the valve controlled by electric actuator.Two, the linear properties of flow and valve shaft corner improves, and because the hole in plane is easy to be processed into rule or gradual change form, make the corresponding flow that turns an angle, linear properties easily controls and realizes, and makes flow scale more regular.Three, the turn-off function that flow control valve had, this type of traditional valve does not possess turn-off function, and vent flow is very large, even if be adjusted to by flow minimum, still can not meet usage requirement.A cutting-off valve must be installed again additional when needs turn off rate-of flow, the application of Flow valve is restricted, installing space and overall cost also corresponding increase.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1 safe screw mandrel, 2 motors, 3 trains, 4 safety bearing seats, 5 safe screws, 6 dynamic brake linings, 7 quiet brake linings, 8 position proximity switches, 9 bolts, 10 limit proximity switches.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model comprises safe screw mandrel 1, motor 2, train 3, safety bearing seat 4, safe screw 5, dynamic brake lining 6, quiet brake lining 7, position proximity switch 8, bolt 9 and limit proximity switch 10, motor 2 is connected to safe screw mandrel 1 by train 3, safe screw mandrel 1 is set with successively safety bearing seat 4 and safe screw 5, train 3 lower end is provided with between safe screw mandrel 1 train 3 and safety bearing seat 4 and is provided with position proximity switch 8, dynamic brake lining 6 is located at above safe screw mandrel 1, quiet brake lining 7 is located at safe screw mandrel 1 left side, limit proximity switch 10 is located at below dynamic brake lining 6.
The resolution of position proximity switch 9 is 0.5mm.
When motor 2 drives train 3 to rotate, position proximity switch 8 detects safe screw 5, brake lining displacement (because pitch is constant, namely pulse signal is brake lining running position) pulse signal.After learning brake lining position, mass flow can be obtained by (2-1) formula.
In formula, Q-flow, K-filling index, g-gravity accleration, t-time, P-unit weight.
(2-1) formula also can obtain aperture under flow learning, reaches the object controlling flow.
Controlling method: after instrument or upper computer detection to umber of pulse, enforcing location flow control.
Limit proximity switch 10 for electrical equipment limit position control and arrange, to improve this system works reliability.
Last it is noted that above embodiment only illustrates the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
