Feedback board, first end are fixed on the transmitter of the valve position, and second end passes through valve position screw rod;
When manual-operating mechanism driving stem moves up and down, valve position screw rod is also and then moved up and down, valve position screw rod band again Second end motion of dynamic feedback board so that feedback board generates angle on a horizontal, and changes according to the mobile angle of feedback board Become the curent change of valve position transmitter output, further adjusts the aperture of throttle valve.
Preferably, in the initial state, the first end Yu second end of feedback board are kept on a horizontal;Valve position is set at this time The output electric current of transmitter is 12mA, and sets throttle valve opening value as 50%.
Preferably, under drive of the feedback board in valve position screw rod, it is horizontal in the following, and forming 15 to be moved to original state When the angle of degree, throttle valve opening value is set as 0%, and the output electric current of valve position transmitter is 4mA.
Preferably, under drive of the feedback board in valve position screw rod, it is horizontal above to be moved to original state, and form 15 When the angle of degree, throttle valve opening value is set as 100%, and the output electric current of valve position transmitter is 20mA.
Preferably, include also control room, connect with valve position transmitter, to read the current information of valve position transmitter.
Preferably, the straight line that the rotary motion of the manual-operating mechanism is converted into valve rod moves up and down.
Preferably, valve position transmitter is fixed on the mounting plate being arranged in the hole that connecting bracket side opens up.
The utility model has the technical effect that automatic display throttle valve opening, aperture can with remote synchronization to Central Control Room, And accuracy of reading is high, meets site intelligent requirement.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under The utility model is described in more detail with reference to the drawings and specific embodiments in face, but limitation is not originally practical in any way Novel range.
As shown in attached drawing 1, attached drawing 2, the utility model includes: valve deck (2), is fixed on the upper of throttle body part (1) End, valve rod (3), first end sequentially pass through the valve deck (2) and throttle body part (1);Connecting bracket (4), surrounds The second end of the valve rod (3);Manual-operating mechanism (6), is fixed on the upper end of connecting bracket (4), even with the valve rod (3) It connects, moves down ovable valve stem (3) above;Valve position screw rod (5), is fixed in the hole opened up on the side of valve rod (3);Valve position pick-up Device (7) is fixed on the connecting bracket (4);Feedback board (9), first end are fixed on valve position transmitter (7), Second end passes through valve position screw rod (5);Control room (10) is connect with valve position transmitter (7), to read valve position transmitter (7) Current information.When manual-operating mechanism (6) driving stem (3) moves up and down, valve position screw rod (5) is also and then moved up and down, Valve position screw rod (5) drives the second end motion of feedback board (9) again, so that feedback board (9) generates angle on a horizontal, and according to The mobile angle of feedback board (9) changes the curent change of valve position transmitter (7) output, further adjusts the aperture of throttle valve.
As shown in Fig. 3, it first has to adjust mounting plate (8) up and down, makes the feedback board being set on valve position transmitter (7) (9) second end of first end and the feedback board (9) being arranged on valve position screw rod (5) is kept on a horizontal, state definition For original state.The output electric current and signal for setting valve position transmitter as the median 12mA of 4~20mA of transmitter output area, And it sets throttle valve and is in 50% aperture state.
As shown in Fig. 4, rotation manual operating mechanism (6), so that the straight line that rotary motion is converted into valve rod (3) is transported up and down It is dynamic.Under drive of the feedback board (9) in valve position screw rod (5), it is horizontal in the following, and forming 15 degree of angle to be moved to original state When spending, throttle valve opening value is set as 0%, and the output electric current of valve position transmitter is 4mA.When feedback board (9) is in valve position screw rod (5) under drive, when it is horizontal above to be moved to original state, and forming 15 degree of angle, set throttle valve opening value as 100%, and the output electric current of valve position transmitter is 20mA.
After the completion of setting, the difference of angle is rotated according to feedback board, the electric current of transmitter output also generates variation, at this time 4mA~20mA is 0%~100% opening value for having corresponded to throttle valve.
It is discussed in detail although the content of the utility model has passed through above-mentioned preferred embodiment, but it should be appreciated that above-mentioned Description be not considered as the limitation of the utility model.After those skilled in the art have read above content, for this reality It all will be apparent with novel a variety of modifications and substitutions.Therefore, the protection scope of the utility model should be by appended power Benefit requires to limit.
