圧との差によるフラツパの機械的変位をノズルの
背圧変位に変換するノズルフラツパ装置に関する
ものである。[Detailed Description of the Invention] The present invention relates to a nozzle flapper device that converts mechanical displacement of the flapper due to a difference between set pressure and measured pressure in a pneumatic regulator or the like into back pressure displacement of the nozzle.

るノズル２の背圧変化が出力として送出される。 FIG. 1 is a schematic configuration diagram of a conventional nozzle flapper device of this kind. This will be explained based on the figure. One end of a plate-shaped flapper 1 is swingably supported, and near the other end there is always a Nozzles 2 that supply a predetermined air pressure are provided facing each other. In addition, the free end of a lever 4, which is integrally provided on the rotatable input shaft 3 in substantially parallel to the flapper 1, includes:
Adjustment screw 5 is screwed in, and flapper 1
Between the lever 4 and the flapper 1, an adjusting screw 5 is inserted between the flapper 1 and the lever 4.
A bias spring 6 is attached that biases it toward the side.
When the input shaft 3 rotates due to the displacement of the input, the flapper 1 swings via the lever 4 and the adjustment screw 5, and a change in the back pressure of the nozzle 2 due to a change in the gap between its tip and the nozzle 2 is output. Sent as .

その調節が面倒で時間が掛かり、しかも正確な設
定値を得ることが難しいという欠点があつた。 However, in such a conventional nozzle flapper device, since the lever 4 is only fixed to the input shaft 3, the flapper 1 is moved unnecessarily by the force applied from the outside when adjusting the gap with the adjustment screw 5, and the adjustment All the while, noise is generated in the air output provided by the nozzle back pressure. Therefore, when making this adjustment, it is necessary to repeatedly adjust the adjusting screw 5 while checking the output.
The disadvantages are that the adjustment is troublesome and time consuming, and it is difficult to obtain accurate set values.

より前記欠点を除去することができる。 Therefore, in order to eliminate this drawback, an apparatus whose schematic configuration is shown in FIG. 2 was proposed. That is, in this device, the lever 4 and the flapper 1 are connected by a strap 7, and the adjustment screw 5 is screwed into a base 8 separate from the transmission system and has only an adjustment function. By doing this, when operating the adjustment screw 5, other external forces due to the forward and backward movement due to screw rotation do not apply to the flapper 1, so that the extra force does not affect the gap between the nozzle 2 and the flapper 1, and the adjustment is smooth. The above-mentioned drawbacks can be eliminated by providing reliable output and making it possible to make adjustments while reading this output.

The fixation of the flapper 1 tends to become unstable, and if this becomes unstable, the flapper 1 may rotate horizontally with the rotation of the adjustment screw 5, or the contact with the adjustment screw 5 may shift when the flapper 1 swings. , it is also susceptible to instrument vibration.

いノズルフラツパ装置を提供するものである。 The present invention was developed in view of the above points, and the central part of the flapper is shaped like a cross at the free end of a flexible member having two mutually orthogonal planes and one end fixed to a support member. By supporting the flapper via a pair of leaf springs and by providing a hand screw for adjusting the gap between the flapper and the nozzle between the flexible member and its fixed member, the flapper can be swung only in the direction of adjusting the gap. To provide a nozzle flapper device that is resistant to vibrations and free from unexpected disturbances.

る。 FIG. 3 is a schematic configuration diagram of a nozzle flapper device according to the present invention. In the figure, a flexible plate 12 as a flexible member formed in an L-shape having two mutually orthogonal planes is fixed in parallel to a bracket 11 fixed to the housing side of the instrument. Leaf springs 13 and 14 are fixed to the long and short sides of the flexible plate 12, respectively, so as to be substantially orthogonal to each other. On the other hand, the flapper 15 is bent at the center to form an N-shape, and one free end of the flap is bent at the center.
It is connected to a displacement member on the input side (not shown) by a strap 16. And this fratsupa 1
5 has both members perpendicular to each other at the center supported by the free ends of the leaf springs 13 and 14, respectively, and the free end on the opposite side to the input side faces the nozzle 17. . Further, a gap adjusting means between the flapper 15 and the nozzle 17 is provided between the flexible plate 12 and the bracket 11, which is a fixing member thereof. That is, bracket 11
An adjusting screw 18 is screwed into the , and its tip is pressed against the flexible plate 12 .By rotating the adjusting screw 18 and moving it forward and backward, the flexible plate 12 swings, and the leaf spring 13 , The flapper 15 supported through the flapper 14 is configured to swing to adjust the gap between its free end and the nozzle 17.

Since it swings around the support part 14, the gap between the flapper 15 and the nozzle 17 changes. Therefore, the back pressure of the nozzle 17 changes, and this back pressure change is delivered as an output. When adjusting the gap between the flapper 15 and the nozzle 17,
When the adjusting screw 18 is rotated to advance or retreat, the flexible plate 12 swings, and the flapper 15 integrated therewith swings to adjust the gap between the flexible plate 12 and the nozzle 17.

ることがない。 In the nozzle flapper device that operates in this way, the flapper 15 is made of flat leaf springs 13 and 14.
The flapper 15 is supported by the flexible plate 12 and does not deform in the width direction even if it deforms in the thickness direction, so the flapper 15 can only swing in the direction of adjusting the gap with the nozzle 17. , it will not swing in any other direction. Therefore, the adjusting screw 18
The flapper 15 is stable not only when adjusting the gap, but also during the swinging operation of the flapper 15, and there is no unexpected disturbance, and the output does not change even if a meter or the like vibrates.

れる。 As is clear from the above description, according to the present invention, a cross-shaped flexible member is formed at the free end of the flexible member, which has two mutually orthogonal planes at the center of the flapper of the nozzle flapper device and has one end fixed to the support member. By supporting the flapper through a pair of leaf springs and by providing a hand screw between the flexible member and its fixed member to adjust the gap between the flapper and the nozzle, the flapper can be stably supported and connected to the nozzle. Since it can only swing in the gap adjustment direction and will not shift laterally, there will be no unexpected disturbances not only when adjusting the gap between the flapper and the nozzle, but also during control operations.
It is extremely resistant to vibrations and operates reliably, and it is easy to adjust the gap to obtain accurate set values.
