Specific embodiment
In order to keep the present invention more obvious and easy to understand, the present invention is done furtherly below in conjunction with the drawings and specific embodiments
It is bright.
As shown in Fig. 1 and Fig. 2 combination, the mechanical aperture feedback device of the throttle valve that surges of the invention includes guide rail 3, gas
Pressure regulator valve mandril 4, gas pressure regulation valve support 5, gas pressure regulating valve 6 and aperture table E.
Wherein, guide rail 3 is mounted on piston rod 2, and can be moved together with piston rod 2, and gas pressure regulating valve 6 is fixed on gas
In body pressure regulation valve support 5, gas pressure regulating valve 6 is connected with gas pressure regulating valve mandril 4, and guide rail 3 and the gas pressure regulating valve mandril 4 connect
It connects, several gas source inlets is provided on gas pressure regulating valve 6, when gas pressure regulating valve mandril 4 moves (i.e. left and right along horizontal direction
It is mobile) when, by compressed air, the pressure of 6 output end of gas pressure regulating valve can change, so as to show opening for the throttle valve that surges
Degree.
Wherein, skewed slot, gas pressure regulation are provided on side (left side) surface of gas pressure regulating valve mandril 4 on guide rail 3
4 left part of valve mandril, which is placed in the skewed slot of guide rail 3, can carry out rolling movement.Wherein, the left side of gas pressure regulating valve mandril 4
It is provided with the crank block slider structure that rolling movement can be converted into linear motion or cam structure or gear & rack structure or ball
Screw structure etc., so that gas pressure regulating valve mandril 4 can side-to-side movement when guide rail 3 moves up and down.
As shown in Fig. 2, throttle valve working principle of surging are as follows: the handle of operation hand-operated direction valve B, the throttle valve that surges execution are opened
Pass movement, makes hydraulic oil enter oil cylinder, then the oil inlet of throttle valve toucher epicoele by hydraulic power source oil inlet, and flow control valve A is used
In the oil inlet speed for adjusting hydraulic oil, piston rod 2 is moved downward at this time.Wherein, the exit of gas pressure regulating valve 6 and aperture table E
Connection, open degree feedback are responsible for by gas pressure regulating valve D, and valve position is responsible for by aperture table E.
When piston rod 2 moves downward, the throttle valve opening that surges constantly reduces, while guide rail 3 is transported downwards with piston rod 2
Row, then the operation (close to the direction of 3 side of guide rail), the pressure of 6 output end of gas pressure regulating valve are continuous to the left for gas pressure regulating valve mandril 4
Reduce, so that the numerical value of aperture table E constantly reduces.When piston rod 2 runs to extreme position, the throttle valve that surges is closed, aperture
Table E shows that valve opening is 0 (minimum scale value).Wherein, the left side of gas pressure regulating valve mandril 4, which is provided with, to turn rolling movement
Change the crank block slider structure or cam structure or gear & rack structure or ball screw arrangement of linear motion into.
Similarly, when piston rod 2 moves upwards, the throttle valve opening that surges is continuously increased, at the same guide rail 3 with piston rod 2 to
Upper operation, then (direction far from 3 side of the guide rail) operation to the right of gas pressure regulating valve mandril 4, the pressure of 6 output end of gas pressure regulating valve
Constantly increase, so that the numerical value of aperture table E is consequently increased, when the operation of piston rod 2 to reverse limit position, surge throttle valve
It opens, aperture table E is shown as maximum scale value (such as maximum scale value is 100).
As an embodiment of the present invention, when live compressed air gas source pressure need to meet 60psi or more；Of the invention
Aperture table is used to show the aperture of the throttle valve that surges, is set as customizing pressure gauge, figure 0-100, then the scale institute
Corresponding pressure value is 0-60psi.Of the invention surging throttles stroke of valve as 40mm, and the aperture for the throttle valve that surges is linear.
As shown in Figure 1, when the throttle valve that surges is by standard-sized sheet to full pass process, the total 40mm of operation up and down of piston rod 2, by leading
Skewed slot on rail 3, gas pressure regulating valve mandril 4 or so run certain distance, such as 11mm, the compressed air gas of the distance and setting
Source pressure size is corresponding, when the throttle valve that surges for being directed to different trips, by adjusting the skewed slot gradient of guide rail 3, it is ensured that
The range ability of gas pressure regulating valve mandril 4 is 11mm.At the same time, the exit pressure levels of gas pressure regulating valve 6 will can constantly increase from 0
Up to 60psi, then the aperture meter reading with the outlet of gas pressure regulating valve 6 connection correspondingly can increase to 100 from 0.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
