Abstract
The invention provides an electronic vacuum valve to solve the problem that in the prior art, the open and close of a valve are achieved through a manual operational valve rod, and thus valve damage is easily occurred. The electronic vacuum valve comprises a vacuum sleeve pipe, a valve body, a valve rod and a valve core, and further comprises 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 outputs pulse signals. The signal amplifier conducts power amplification to the pulse signals. The output end of the servo motor is connected with the top end of the valve rod through a coupler, and the control end of the servo motor is connected to the output end of the signal amplifier.
Description
Technical field
The present invention 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 the adiabaticity that the control valve of closed procedure can destroy pipeline and in pipeline, use a large amount of needs.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 attended operation handle of flange connecting apparatus is passed on the top of valve rod, 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 that forms between the outer wall of sliding sleeve and the valve body, the bottom outside of sliding sleeve is bolted on cryogenic globe valve body top, and 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 the above-mentioned patent application are mechanical structure, need workman's execute-in-place, and the situation that valve rod damages appears in the long experience accumulation of size needs for torsion easily during misoperation.
Summary of the invention
The present invention proposes a kind of electronic vacuum valve, has solved in the prior art to realize valve opening and close, occur easily the problem that valve rod damages by the manual operation valve rod.
Technological scheme of the present invention 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 carries out power amplification with 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 invention has the beneficial effects as follows: by the opening and closing of push-button switch control valve, protection valve rod and spool are not subjected to the damage of overburdening external force, have prolonged the working life of equipment.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of a kind of electronic vacuum valve of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Electronic vacuum valve of the present invention comprises 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 is exported corresponding pulse signal according to turning on and off signal; Signal amplifier 30 carries out power amplification with pulse signal; Actuating motor 40, its output terminal is connected by the top of coupling with valve rod 50, and control end is connected to the output terminal of signal amplifier, operates according to the pulse signal of controller 20.
Preferably, controller 20 is single-chip microcomputer, and push-button switch 10 is normally closed push button switch.
The invention has the beneficial effects as follows: by the opening and closing of push-button switch control valve, protection valve rod and spool are not subjected to the damage of overburdening external force, have prolonged the working life of equipment.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
