Description

Technical Field

[0001] This utility model relates to the field of amplifier equipment technology, specifically to an amplifier for a smart locator. Background Technology

[0002] Amplifiers are widely used in various devices such as communications, broadcasting, radar, television, and automatic control. Amplifiers are often used in smart positioners. By adding an amplifier, the signal strength received by the positioner can be significantly improved, thereby improving the positioning accuracy. However, in existing positioner amplifiers, the double-hole diaphragm is subjected to the greatest impact and stretching when the valve seat moves. After long-term use, the double-hole diaphragm is prone to deformation, which leads to damage to the amplifier function and inability to control accurately. Utility Model Content

[0003] In existing amplifiers, the double-hole diaphragm is subjected to the greatest impact and stretching when the valve seat moves, and the double-hole diaphragm is prone to deformation, which leads to damage to the amplifier function and inability to accurately control defects. This utility model provides an amplifier for an intelligent positioner, which can reduce the impact and stretching of the double-hole diaphragm, making the double-hole diaphragm less prone to deformation, and its amplifier function is less likely to be damaged, making it easier to control accurately.

[0004] This utility model provides the following technical solution:

[0005] It includes a top cover and a bottom cover. The bottom cover has a stepped internal cavity with an annular groove for matching components on its cavity end face. The top cover is bolted to the bottom cover, forming an amplifier working cavity. The amplifier working cavity has a double-hole diaphragm structure. The double-hole diaphragm structure includes a first double-hole diaphragm, a second double-hole diaphragm, a single-hole diaphragm, a voltage stabilizing ring, and a flat pressure ring. The bottom cover has a slidingly connected valve seat and valve core in its internal cavity. The first double-hole diaphragm, the flat pressure ring, the second double-hole diaphragm, and the voltage stabilizing ring are sequentially attached to form a double-hole diaphragm assembly, which is fitted onto the valve seat. A small pressure plate and a large pressure plate are installed at the outwardly protruding end of the valve seat. A spacer is provided between the small pressure plate and the valve seat, and the spacer is fitted onto the valve seat. The spacer formed by the first double-hole diaphragm, the second double-hole diaphragm, the spacer, and the flat pressure ring constitutes a compartment.

[0006] Its further features are:

[0007] A single-hole diaphragm is provided in the gap between the small pressure plate and the large pressure plate. The single-hole diaphragm is fitted onto the protruding part of the large pressure plate. One end face of the single-hole diaphragm is attached to the end face of the pressure stabilizing ring, and the other end face is attached to the driving pressure ring. The end of the driving pressure ring extends into the top cover and presses the non-porous diaphragm against the inner wall of the top cover.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] The two double-hole diaphragms distribute the driving force borne by the central moving component at its extreme position, reducing the tensile impact on the double-hole diaphragms during amplifier operation. The double-hole diaphragms are less prone to deformation, and the double-hole diaphragm design reduces the valve seat and valve core misalignment caused by long-term use, increases the stability of the central moving component, makes the amplifier function less likely to be damaged, and facilitates precise control by the operator.

[0010] The compartment formed by the space enclosed by the first double-hole diaphragm, the second double-hole diaphragm, the spacer ring, and the flat pressure ring increases damping, making the amplifier system more stable and reducing amplifier overshoot, thus increasing the amplifier's service life.

[0011] The spacer ring has an anti-surge function. By adjusting the tolerance between the valve seat and the spacer ring, the compartment exhaust buffering effect can be achieved. Attached Figure Description

[0021] This utility model provides, for example Figure 1 An amplifier for a smart locator is shown, comprising a top cover 1 and a bottom cover 2, see Figure 7The bottom cover 2 has a stepped internal cavity with an annular groove for matching components on its cavity end face. The top cover 1 is bolted to the bottom cover 2, forming an amplifier working cavity. A double-hole diaphragm structure is provided within the amplifier working cavity. This double-hole diaphragm structure includes a first double-hole diaphragm 6, a second double-hole diaphragm 15, a single-hole diaphragm 5, a voltage stabilizing ring 4, and a flat pressure ring 14. A valve seat 8 and a valve core 9 are slidably connected within the internal cavity of the bottom cover 2. The first double-hole diaphragm 6, the flat pressure ring 14, the second double-hole diaphragm 15, and the voltage stabilizing ring 4 are sequentially fitted together to form a double-hole diaphragm assembly, which is then fitted onto the valve seat 8. A small pressure plate 10 and a large pressure plate 11 are fitted onto the outwardly protruding end of the valve seat 8. (See...) Figure 5 A spacer 12 is provided between the small pressure plate 10 and the valve seat 8. The spacer 12 is fitted onto the valve seat. The space enclosed by the first double-hole diaphragm 6, the second double-hole diaphragm 15, the spacer 12, and the flat pressure ring 14 forms a compartment A.

[0022] See Figure 3 A single-hole diaphragm 5 is provided in the gap between the small pressure plate 10 and the large pressure plate 11. The single-hole diaphragm 5 is fitted onto the protruding part of the large pressure plate 11. One end face of the single-hole diaphragm 5 is attached to the end face of the pressure stabilizing ring 4, and the other end face is attached to the driving pressure ring 13. The end of the driving pressure ring 13 extends into the top cover 1 and presses the non-porous diaphragm 7 against the inner wall of the top cover 1.

[0023] Working principle of this utility model:

[0024] Adjusting the pressure B in the nozzle back pressure chamber drives the non-porous diaphragm 7 to reciprocate the entire moving part, thereby sealing or disengaging the valve core 9 from the valve seat 8. This controls the inflation and deflation of the cylinder and adjusts the valve opening. The two double-hole diaphragms share the driving force of the central moving component at its limit position and are not prone to deformation. The arrangement of the first double-hole diaphragm 6, the second double-hole diaphragm 15, the spacer 12, and the flat pressure ring 14 forms a compartment A, which increases damping and reduces overshoot. The length of the valve seat 8 improves guidance and increases the initial concentricity of the valve seat and valve core assembly.
