Abstract
The utility model discloses an electronic vacuum valve, and is used for solving the problem that a valve rod is easy to damage because of manually controlling the valve rod to realize the opening and closing of the valve in the prior art. The electronic vacuum valve comprises a vacuum sleeve, a valve body, a valve rod, a valve core, a button switch, a controller, a signal amplifier and a servo motor, wherein the input end of the controller is connected with the button switch, and the controller is used for outputting a pulse signal; the signal amplifier is used for carrying out power amplification on the pulse signal; and the output end of the servo motor is connected with the top end of the valve rod through a coupler, and the controlling end of the servo motor is connected with the output end of the signal amplifier.
Description
Technical field
The utility model relates to the industrial control valve field, particularly a kind of electronic vacuum valve.
Background technique
Liquid oxygen (183 ℃), liquid nitrogen (196 ℃) and liquid argon (186 ℃) exist temperature very low, therefore, in these cryogenic liquides of transmission, require the necessary heat-insulating property of delivery line good, reduce as far as possible the heat exchange with external environment.Often open and use a large amount of needs in pipeline the adiabaticity that the control valve of closed procedure can destroy pipeline.201220228270.4 number Patent Application Publication a kind of Cryo Heat Insulation vacuum valve, the vacuum sleeve and the valve body that comprise vertical connection, the two ends of vacuum sleeve connect respectively the reducing shrouding, the inside of valve body is provided with valve rod, the top fastening flange connection set of valve body, the top of valve rod is through the top attended operation handle of flange connecting apparatus, the below, bottom of valve rod is provided with the cryogenic globe valve body, the bottom of valve rod is connected with the spool that extend into cryogenic globe valve body inside, the outer wall of valve rod is provided with sliding sleeve, be provided with the foamed thermal insulating layer in the cavity formed between the outer wall of sliding sleeve and valve body, the bottom outside of sliding sleeve is bolted on cryogenic globe valve body top, the two ends of cryogenic globe valve body are respectively equipped with the interface for the connecting conveying pipe road.Operating grip and valve rod in above-mentioned patent application are mechanical structure, need workman's execute-in-place, and the situation that valve rod damages, easily appear in the long experience accumulation of size needs for torsion during misoperation.
The model utility content
The utility model proposes a kind of electronic vacuum valve, solved in the prior art and realized valve opening and close, easily occur the problem that valve rod damages by the manual operation valve rod.
The technical solution of the utility model is achieved in that
A kind of electronic vacuum valve comprises: vacuum sleeve, valve body, valve rod and spool also comprise: push-button switch; The controller that input end is connected with described push-button switch, output pulse signal; Signal amplifier, carry out power amplification by described pulse signal; The actuating motor that output terminal is connected with described valve stem tip by coupling, control end is connected to the output terminal of signal amplifier.
Alternatively, described controller is single-chip microcomputer.
Alternatively, described push-button switch is normally closed push button switch.
The beneficial effects of the utility model are: by the opening and closing of push-button switch control valve, protection valve rod and spool are not subject to the damage of overburdening external force, have extended the working life of equipment.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The control block diagram that Fig. 1 is a kind of electronic vacuum valve of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment who obtains, and all belong to the scope of the utility model protection.
Electronic vacuum valve of the present utility model, comprise vacuum sleeve of the prior art, valve body, valve rod and spool, as shown in Figure 1, also comprises: push-button switch 10; The controller 20 that input end is connected with push-button switch 10, the receiving key control signal, export corresponding pulse signal according to turning on and off signal; Signal amplifier 30, carry out power amplification by pulse signal; Actuating motor 40, its output terminal is connected with the top of valve rod 50 by coupling, and control end is connected to the output terminal of signal amplifier, according to the pulse signal of controller 20, is operated.
Preferably, controller 20 is single-chip microcomputer, and push-button switch 10 is normally closed push button switch.
The beneficial effects of the utility model are: by the opening and closing of push-button switch control valve, protection valve rod and spool are not subject to the damage of overburdening external force, have extended the working life of equipment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
