Abstract
The utility model provides a can realize pressure control's butterfly valve, relates to valve body control technical field, including butterfly valve, cavity, controller, and pressure sensor, its characterized in that: install pressure sensor on the cavity, pressure sensor is connected to the controller through the wire, install the butterfly valve on the outlet duct of cavity, the butterfly valve passes through the wire and links to each other with the controller, and the control to the butterfly valve angle of release can be realized to the controller to gaseous flow in the control outlet duct. Through with butterfly valve and controller, pressure sensor is connected and forms a closed -loop with cavity, outlet duct, has realized the accurate control to chamber pressure, has solved chamber pressure unmanageable problem in the mobile atmosphere, at butterfly valve both ends installation clamp, can be convenient carry out the dismouting to the butterfly valve and maintain.
Description
Technical field
This utility model relates to valve body technical field, particularly to a kind of butterfly valve.
Background technology
In all multi-reaction chambers or cavity, need to keep cavity to be in certain pressure, when atmosphere in cavity
When being in flow regime, such as one end air inlet other end is given vent to anger, and will accurately keep cavity to be on the pressure side not easy
Control, be typically all and control air inlet body end pressure by pressure regulator valve, then given vent to anger by outlet side Valve controlling
Flow, but this control mode is in side when different periods needs to change pressure for cavity is not easy reality
Existing, and degree of accuracy can not meet related process requirement.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that Yi Zhongke
Realize pressure controlled butterfly valve.
Technical problem to be solved in the utility model uses following technical scheme to realize:
One can realize pressure controlled butterfly valve, including butterfly valve, and cavity, controller, pressure transducer,
Described cavity one end is connected with air inlet pipe, and the other end is connected with escape pipe, is provided with pressure on described cavity
Force transducer, described pressure transducer is wired to controller.It is provided with on the escape pipe of cavity
Butterfly valve, described butterfly valve is connected with controller by wire, and described controller can realize the control to butterfly valve angle of release
System, thus the flow of gas in controlling escape pipe.
Safeguarding butterfly valve for convenience, the Pipe installing at butterfly valve two ends has clip, to facilitate butterfly
Valve dismounts.
When gas enters cavity by air inlet pipe, react in cavity, subsequently by bank of tubes of giving vent to anger
Going out, when chamber pressure is controlled in a setting value by needs, it is real that first pressure transducer detects chamber pressure
Actual value, and signal is fed back to controller, signal that pressure transducer is transmitted by controller and setting
Value contrasts, and when actual value is more than or less than setting value, is slowly regulated by the angle of release size of butterfly valve
The flow velocity of eluting gas, finally makes the pressure that pressure transducer detects equal to setting value.
The beneficial effects of the utility model are: by by butterfly valve and controller, pressure transducer is connected also
Form a closed-loop path with cavity, escape pipe, it is achieved that the accurate control to chamber pressure, solve stream
Take offence the unmanageable problem of chamber pressure in atmosphere, clip is installed at butterfly valve two ends, can be easily to butterfly valve
Carry out dismounting to safeguard.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect
White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.
As it is shown in figure 1, one can realize pressure controlled butterfly valve, including butterfly valve 5, cavity 1, controller 4,
Pressure transducer 7, cavity 1 one end is connected with air inlet pipe 2, and the other end is connected with escape pipe 3, on cavity 2
Being provided with pressure transducer 7, pressure transducer 7 is connected to controller 4 by wire 6.Giving vent to anger of cavity 1
Being provided with butterfly valve 5 on pipe, butterfly valve 5 is connected with controller 4 by wire 8, and controller 4 can realize butterfly valve 5
The control of angle of release, thus the flow of gas in controlling escape pipe 3.
Safeguarding butterfly valve 5 for convenience, the Pipe installing at butterfly valve 5 two ends has clip 9, right to facilitate
Butterfly valve 5 dismounts.
When gas enters cavity 1 by air inlet pipe 2, react in cavity 1, pass through escape pipe subsequently
3 discharge, when needs by cavity 1 Stress control in a setting value time, pressure transducer 7 first detects chamber pressure
Actual value, and signal is fed back to controller 4, the signal that pressure transducer 7 is transmitted by controller 4 with
Setting value contrasts, when actual value is more than or less than setting value, by the angle of release size of butterfly valve 5 slowly
The flow velocity of regulation eluting gas, finally makes the pressure that pressure transducer 7 detects equal to setting value.
Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described
Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned
Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description
On the premise of spirit and scope, this utility model also has various changes and modifications, these changes and improvements
In the range of both falling within claimed this utility model.This utility model claims scope by appended power
Profit claim and equivalent thereof define.
