[0017] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0018] A kind of Figure 1-2 The high-precision valve position display thrust plate device shown is used in conjunction with a valve. It includes a thrust plate bracket 2 for dynamically sealing and positioning the valve stem 8. The lower end of the thrust plate bracket 2 is fixedly connected to a mounting plate 4. The valve stem 8 extends into the range of the mounting plate 4. A connecting block 10 is axially slidably provided in the mounting plate 4. The valve stem 8 passes through the connecting block 10 and is fixedly positioned therewith.

[0019] A fixed ruler 5 is fixed to the mounting plate 4 in the axial direction, and a readable movable ruler 6 is slidably fitted on the fixed ruler 5. The readable movable ruler 6 is positioned on the connecting block 10, wherein the connecting block 10 has an axial slide groove and an adjusting slider 13 slidably fitted in the axial slide groove. The adjusting slider 13 has a long hole along the axial direction. The adjusting slider 13 can be adjustably positioned on the connecting block 10 through the long hole and the slider screw 12, and a positioning pin 14 is also provided on the adjusting slider 13. An extended positioning portion that can be axially perpendicular to the adjusting slider 13 is extended from the side of the readable movable ruler 6, and a transverse strip hole is provided on the extended positioning portion, and the positioning pin 14 is fitted in the transverse strip hole.

[0020] Here, the valve stem 8 is cooperatively connected with the valve power stem.

[0021] The valve stem 8 is positioned on the thrust plate bracket 2 through the thrust plate 1, and the thrust plate 1 is fixedly connected to the thrust plate bracket 2 by the first bolt 9; the mounting plate 4 has a pair of guide rails facing each other and symmetrically arranged with the valve stem 8 as the center of symmetry. After the valve stem 8 passes through the thrust plate bracket 2, it is threadedly fitted with the connecting block 10, and the two sides of the connecting block 10 are slidably fitted on the guide rails.

[0022] The thrust plate 1 applies axial thrust to the valve stem 8. Its structure and principles are well known in the prior art and are not further elaborated in this embodiment. The mounting plate 4 can be a hollowed-out structure, or it can be a split hollowed-out structure. This hollowed-out structure facilitates the operator's positioning and adjustment of the readable movable ruler 6 and data reading. The following description focuses on the split hollowed-out structure.

[0023] Mounting plates 4 consist of two left and right panels, each secured to the underside of the thrust plate bracket 2 by mounting plate fixing screws 3. Guide rails are integrally formed on each mounting plate 4 to ensure structural stability. Connecting block 10 slides on both sides of the guide rails. Connecting block 10 is also fixed to the valve stem 8. In this case, while threadedly engaged with the valve stem 8, a flat key 15 is provided between the two to enhance positional stability.

[0024] In order to improve the convenience of assembly, the connecting block 10 is also designed as a split structure. The connecting block 10 is divided into two left and right parts with the plane where the pair of guide rails are located as the dividing surface. The left and right parts are fastened together by a second bolt 11.

[0025] The adjustment slider 13 in this case is an L-shaped structure, with the vertical portion of the L-shaped structure slidingly fitting within the axial slot. A long hole is provided in the vertical portion, and a threaded positioning hole is provided in the axial slot. The slider screw 12 locks and positions the adjustment slider 13 through the threaded positioning hole, and the adjustment slider 13 can be adjusted up and down as needed. A positioning pin 14 is provided on the horizontal portion of the L-shaped structure, cooperating with a horizontal strip hole on the extended positioning portion of the readable movable ruler 6 to prevent rigid obstruction between the connecting block 10 and the readable movable ruler 6 during the axial movement of the valve stem 8. The cooperation between the horizontal strip hole and the positioning pin 14 ensures synchronous axial movement between the readable movable ruler 6 and the valve stem, thereby ensuring accurate data measurement of the readable movable ruler 6.

[0026] Finally, the surface of the fixed ruler 5 is sprayed with a layer of magnetic induction material, on which scale values ​​are set, and its two ends are fixed to the mounting plate 4 by fixed ruler fixing screws 7; the readable movable ruler 6 is a magnetic induction electronic ruler, which is placed on the fixed ruler 5 and slides on it. As for the magnetic induction electronic ruler, its measurement principle and structure are already very mature in the existing technology. In this case, it is combined with it for synchronous displacement measurement of the valve stem 8. The functional buttons on it, such as the 0-point calibration button 6-1, the measurement unit selection button 6-2, the display 6-3 and the start switch 6-4, all belong to the existing technology. At the same time, a signal transmitting end is provided on the readable movable ruler 6 to connect the signal with the external smart terminal. The remote control of signal transmission and reception, and connection with the smart terminal to obtain data is widely used in the existing technology and has almost become common knowledge. Therefore, the working principle and structure of the magnetic induction electronic ruler will not be redundantly described here.
